Products

Cutting edge reliability

Food and beverage processes require high reliability. All ABB drives undergo extensive testing prior to customer delivery. Furthermore, to increase reliability, drives can be equipped with varnished circuit boards.

Minimized operational and maintenance costs

An ABB drive will pay for itself through energy cost savings relatively quickly. By using the correct process speed, the energy is saved, scrap material is reduced, and quality costs are kept under control. For example, the high electrical costs of operating cold storages can be reduced by varying the motor’s speed. Smooth, accurate and fast control of process speed reduces mechanical wear. The reliability of ABB drives reduces downtime leading to increased process output.

Drives for harsh conditions

With combustible dust found in fl our and grain handling industries, the risk of ignition is high. Special requirements are set for machine surface temperatures, bearings and critical components. For these special protection areas ABB offers ATEX and dust ignition proof (DIP) certifi ed drives and motors.

Freedom to interface with plant control systems

ABB drives offer the widest range of serial link/ fi eldbus as well as ethernet communication. Fieldbus technology enables process equipment to integrate with plant control systems. This improves the process control as well as knowledge/information collection from the process. ABB drives can be equipped with most of the commercial fi eldbus systems and have the widest variety of protocols.

Fast response to increased processing demands

ABB drives’ fl exible application macros, together with state-of-the-art motor control features, ensure accurate and fast response times to process fl ow demands. For example, the application control macro for pumps commands the drive to start additional pumps in response to pressure drops, should there be a surge in demand. As well as dedicated pump control, the drive provides a pre-pressurization for process start-ups.

ABB industrial drives - regenerative drives, 5.5 to 2500 kW, 230 to 690 V

The regenerative drives feature an inbuilt active supply unit that allows full power in motoring and generating modes. Transition between the modes is quick due to the ultra-fast Direct Torque Control

(DTC). Regenerative drives with extensive adaptation capabilities are suitable for all demanding applications where braking is needed, such as centrifuges and many conveyors.

Energy effi ciency

Signifi cant energy savings as braking energy is returned back to the supplying electrical network, rather than wasted as heat as with traditional braking.

Uninterrupted performance

Thanks to DTC, the transition from motoring to braking (generating) is very fast. These kinds of fast torque changes, dynamic braking and superior speed and torque control are all possible. The active supply unit and DTC can lower the risk of blown fuses or other component damages due to voltage drops in the network.

Boosted motor voltage

An active supply unit allows the motor output voltage to be boosted, to guarantee full motor voltage even when the supply voltage is below nominal. This helps in motor selection, as network fl uctuations need not be considered.

Cam disk

Electronic cam disk function simulates the operation of a mechanical cam. Together with a synchronous gear, the cam disk enables a master and follower position. When the master rotates, for example to 65 degrees, the follower runs at 90 degrees in relation to the master. DriveCam, a graphical programming tool, determines the values.

Positioning

16 sets of position references are featured. Fieldbus enables an unlimited number of positions.

Synchronizing

An optical link from one drive to another drive transfers the reference from the master drive to the follower. Encoder feedback can also be selected from the load side and adjusted with the electrical encoder gear function.

Cyclic corrections

There are several modes for cyclic corrections. For example, if the position between two conveyors (master- follower set-up) has to be corrected, actual positions are read by sensors. This information is used to correct the position by adjusting the speed of the follower drive.

Control locations

Two different control locations can be selected by digital inputs or fi eldbus. This means that control mode (speed, torque, positioning, synchronizing) can be selected online.

Biscuit maker achieves 100 percent reliability target

ChallengeLU Finland Ltd produces Domino, the country’s leading brand of biscuit.

Weighing of ingredients for the biscuit fi llings is critical and must be very accurate. Screw conveyors dose the fl our and sugar, needed to make these fi llings, onto the weighing scales. The company needed an AC drive to achieve accurate acceleration and deceleration ramps and speed references for the screw conveyor so to give the required dosing.

The fi lling of the biscuits is a continuous operation and needs an AC drive capable of high static speed accuracy. The process can not tolerate any speed rippling or fl uctuation. A good, initial fast speed ramp is important to prevent waste at start-up.

SolutionTo meet these needs, two ABB general machinery drives are installed. One drive controls the screw conveyors that dose and sift the fl our and sugar needed to make the fi lling.

The other one is the main drive controlling the speed of the fi lling conveyor. The controlled motor is a 2.2 kW, 400 V ABB induction motor, with a speed of 1,430 rpm. The motor runs the belt conveyor on the fi lling machine through a belt transmission.

■

Benefi tAri Ylitalo, engineering supervisor at LU Finland Ltd. explains the benefi ts brought by the ABB drives: “The reliability of the control is the most important feature to ensure a continuous fl ow in the process. The new ABB drives have been in operation for almost a year now and fully meet our requirement for 100 percent reliability. We feel it is fundamental to keep abreast of the new developments in control technology, because even the slightest new advance might turn out to be a decisive improvement for our process.”

Dairy plant improves its washing process

Challenge With 15 production plants, Valio is Finland’s leading manufacturer of dairy products. Hygiene is of overriding importance to the company and the tanks and pipes used in dairy production are cleaned before each use.

Valio needed an effective system to control the motors driving the pumps in the washing process. The plant uses a variety of different types and combinations of washes, with all wash recipes stored in the plant automation system.

The clean-in-place (CIP) wash cleans the pipes with a wash solution taken from a reservoir, circulates it in the pipes and returns to the reservoir using return pumps. In the CIP wash, the nominal load in the pipes is a fl ow of wash solution which is approximately 30 cubic meters per hour. The average fl ow is about half of the nominal fl ow.

The fl ow rate and pressure in the pipes stay constant for most of the wash cycle, varying only during drainage periods and when the wash solution is being changed.

SolutionTwo ABB general machinery drives are installed in the CIP10 and CIP11 wash lines for pipes. The drives control the wash pressure pumps. The ABB general machinery drives control the speed of the wash pumps through a speed reference supplied by the automation system as a 4-20 mA current signal to the analogue input of the drive.

■

■

Benefi tThe ABB drives’ communication facilities made them easy to integrate with the plant’s process automation system and PLCs.

Since the drives were installed in the wash lines, they have run non-stop with no problems and Valio has not needed to interfere with their operation in any way.

“The number one concern for our pumps and drives is 100 percent reliability to ensure full-time process availability. The ABB general machinery drives run trouble-free since they were put into service and we are completely satisfi ed with these drives,” says Matti Salmi, process manager.

If one of the drive supply phases fails, the drive does not simply stop operating – it gives an alarm and continues at a reduced output, allowing the problem to be noted and addressed.

The drives save space as they are about half the size of the previous drives.

Canning line boiler plant gains 14 percent effi ciency

ChallengeFood producer Heinz needed to replace the existing boiler plant at its site in Wigan, UK. The boiler plant was at the end of its operational life and unable to meet the latest environmental regulations for fl ue emissions.

The Wigan factory produces over 1.3 billion cans of food a year, requiring the generation of 100 tonnes of steam every hour for both space heating and sterilization of canned foods.

The plant operates six days a week and although steam demand is consistent, it ramps up slowly over a period of 36 hours and ramps down over a period of 24 hours. It also varies from summer to winter, when there is a greater demand for heating and more soup is produced.

SolutionTo take account of these variations in demand and to meet the latest environmental regulations, the new energy center has four boilers installed, each with two gas fi red burners supplied by Hamworthy Combustion. The burners are fi tted with fans to push air into the fl ame.

The eight fans are each controlled by 55 kW ABB standard drives which vary the speed of the fans to control the amount of air injected, depending on whether a high or low fl ame is needed. Heinz specifi ed AC drives for use on the plant so that it could take account of the variations in demand.

■

■

Benefi tThis ability to vary the fl ame to match steam demand is expected to make the energy center 14 percent more effi cient than the old steam plant, which relied on mechanical dampers to choke off the air supply. AC drives are more responsive than mechanical dampers, which tend to introduce a time lag when demand changes direction.

Reducing the energy used also cuts the levels of nitrous oxide emissions, allowing Heinz to meet its obligations under the environmental legislation.

Refrigeration temperature control saves 5,667 USD per month

Challenge JMC Ventilation Refrigeration, based in Washington state, USA, specializes in the design and manufacture of custom ventilation and refrigeration systems for potato and onion storage.

Company founder Joel Micka says: “Each potato and onion variety has its own temperature and humidity requirements for optimum quality and our systems need to hold very accurate settings – within a tenth of a degree – to allow food storage up to 12 months.”

SolutionJMC uses ABB standard drives to control fan-motor speed and airfl ow, keeping temperature and humidity at precise settings. The drives enable the fans to run more effi ciently by matching air volume precisely to demand. When air demand decreases, the AC drive slows the motor down, saving energy and helping farmers maximize their sales margins.

Because storage facilities are often located many miles from the main offi ces, the new systems provide safety and effi ciency through remote control and monitoring. Says Micka: “With the old systems using traditional motor contactors, if the motor current increased to a level that was too high, it would trip and shut down the motor and then shut down the whole system until someone checked on the building and restarted it.”

■

■

Benefi tIn a typical installation, used in an onion store, six 18.6 kW drives use about 19.2 kWh at 100 percent speed. If the fans are reduced to 50 percent speed in the winter, when storage volumes are down and the outside temperatures are low, each of the fans use about 2.8 kWh. All six fans at 50 percent speed use less energy than one fan at 100 percent speed. If the six fans are kept at 50 percent during a one month period, savings of 70,848 kWh or 5,667 USD per month can be made.

With the optional intelligent Ethernet module, the drives can be monitored remotely, either through a modem or via the Internet, allowing faults to be quickly diagnosed and solved. Communications can be set up to send an alert via e-mail to the operators to warn them when a fault trip occurs.

Bakery saves 2,500 GBP on energy

ChallengeNorthern Foods uses compressed air in many of the processes at its Riverside Bakery in Nottingham, UK. As part of the company’s continuing efforts to cut energy costs, Northern Foods decided to investigate its compressed air system.

James Whieldon, maintenance analyst for Northern Foods, says: “Our monitoring and targeting software gives us profi les of the compressors and indicated that there were defi nite opportunities to improve the amount of energy they were using.”

SolutionAn energy appraisal by an ABB Drives Alliance partner, confi rmed the energy use fi gures recorded by Northern Foods and the use of a 45 kW ABB standard drive was recommended.

There are three compressors in total: two 30 kW fi xed-speed assist compressors and a 45 kW duty compressor. The drive was fi tted on this compressor, which is in operation all the time. One of the fi xed speed 30 kW compressors is used to top up the pressure when demand increases, while the other is on standby in case one of the others goes down.

Because two out of the three compressors are always running, it was essential to ensure that the fi xed-speed assist compressor only came online when the duty compressor, fi tted with the AC drive, could provide no more air, that is, when it is running at full-speed.

This was achieved by installing a pressure sensor to provide accurate system pressure feedback for the drive’s inbuilt PID controller.

■

■

Benefi tNorthern Foods is saving nearly 2,500 GBP annually on its compressed air system since installing the ABB drive.

Says Whieldon: “We calculate the actual payback time of the project is 1.5 years, achieving an annual saving of 2,450 GBP. But with energy prices rising, the monetary savings will increase.”

Refrigeration pumping system saves 30,000 GBP per year

ChallengeNorthern Foods bakery in Nottingham, UK, produces chilled, pre-prepared foods for supermarkets, using large refrigeration units to store both the ingredients and the fi nished products. The refrigeration units are fed by cooling water pumped by three 75 kW motors.

Soft-start control panels have been used to control the motors since the plant was built in the early 1980s. However, as part of a wide-ranging energy saving plan, Northern Foods was keen to fi nd a way to improve the energy effi ciency of the pumping system.

SolutionA preliminary energy survey of the motors was conducted by the local ABB Drives Alliance partner. The existing soft-start control panels were removed and three 55 kW ABB industrial drives supplied in control panels.

Also supplied was a 4-20 mA analog temperature sensor connected to the drives’ integral PID controller, which uses the return temperature of the chilled water as its feedback signal. When the plant is working hard, the requirement for chilled water increases and the pumps run faster. When the plant is idling at weekends and holidays, the pumps run at a minimum speed, as the return temperature of the chilled water is already cool.

To save space, the drives are side mounted inside the control panels. The drives were installed individually which meant no lost production time as two out of three ran at any one time.

■

■

Benefi tAverage power reduction was found to be 65.2 percent per pump, giving estimated energy cost savings per year of 30,000 GBP with a payback time of 10 months. As well as the energy saving benefi ts, the system also provides accurate control of the chilled water temperature to the plant.

Says Northern Foods’ engineering manager Vernon Humphries: “Our ABB Drives Alliance partner could handle the entire project, from investigating and justifying the plans, to supplying, installing and commissioning. We are very pleased with the ABB drives and they have performed above expectations since installation.”

However, much of the power it used was being wasted. The fan sucked air through the dryer at a rate controlled by a damper in the pipeline. During normal operation, this damper was 95 percent closed, so most of the fan’s energy was being used to suck the air through the narrow constriction.

The fan was badly oversized because the dryer was previously used to process vacuum salt crystals, which are much smaller than the spherical, 2-3 mm diameter particles in granular salt. The fi ne crystals created a far bigger pressure drop across the dryer than today’s coarse product.

The challenge was to fi nd a way of cutting the energy wasted by the dryer because of the oversized fan.

SolutionAn energy survey by the local ABB Drives Alliance partner was carried out to determine what potential savings could be achieved. The solution was to replace the single oversized fan with a smaller version equipped with speed control.

The original fan motor was rated at 337 kW, but the calculations carried out by the ABB Drives Alliance partner showed that 132 kW should be enough to create the draft needed by the dryer.

■

■

Benefi tThe energy saving on the fan equates to over 1.6 GWh a year, a cut of over 60 percent. For an investment of just 20,000 GBP, Salt Union is saving over 100,000 GBP a year.

At Salt Union, energy-saving initiatives are not confi ned to the process. Even the small amount of waste heat now produced by ABB’s AC drive is being put to work warming up the switch room in winter.

Tomato machinery OEM praises drive reliability

ChallengeCatelli Food Beverage CFT, based in Parma, Italy, is one of the world leaders in the manufacture of machinery for making tomato based products.

Because the tomato campaign is relatively short, running for 50 days between July and September, ensuring maximum uptime of its processing machinery is a key requirement. The company needs reliable AC drives to power and control its machinery. It purchases over 300 ABB drives each year, rated from 1.5 to 315 kW.

SolutionA typical tomato production line uses up to 10 drives for a variety of pumping applications including volumetric, extraction, transfer and mono pumps.

The key ingredient that Catelli Food Beverage CFT look for in its drives selection is reliability, as its machinery controls all phases of the production cycle, from raw material to fi nished product. This has given the company the leading position in the manufacture of continuous evaporators, having working capacities up to 13,000 tonnes per day of raw product, working non-stop over several weeks, without any loss in effi ciency.

The company believes that ABB’s motor control platform, Direct Torque Control (DTC), is instrumental in this particular application. Because mono pumps are of the screw-type, they require a high starting torque and current to overcome the friction. Without DTC the motor would burn out and the pump would fail to start.

■

■

Benefi tMany pumps suffer from solidifi cation of the ingredients resulting in machine stoppage. Using an ABB drive, allows the pump to be restarted at a gradual speed, thereby avoiding the damage that would otherwise be incurred if the pump was started with maximum load. Maintenance costs are therefore reduced.

“We have never experienced failures with ABB drives and for this reason we will continue to use the ABB industrial drive range,” says Mr. Alessio Lazarri, technical director at Catelli Food Beverage CFT.

“We have been using ABB drives and motors for over 15 years. We have plenty opportunity to use drives from other manufacturers. But ABB has always been leaders with technology and is always available to service our equipment and needs in general.”

Unusually for an original equipment manufacturer (OEM), Catelli Food Beverage CFT views the energy saving benefi ts of ABB drives as a key factor in the sales of its machinery.

Sugar centrifuge cycle times improved by 20 percent

ChallengeThe Sugar Cane Growers Cooperative of Florida is a 54-member sugar farmers’ cooperative. At its Belle Glade plant, 24,000 tons of sugar cane are ground daily, producing on average 350,000 tons of raw sugar annually. During the October through April harvest season, the plant operates 24 x 7.

The Cooperative decided to replace the drive control on a Titan 1750 centrifuge, which has a 450 hp (335 kW) motor. The existing drive was outdated, tripped frequently and was expensive to repair, resulting in shutdowns. Because space was scarce, the Cooperative wanted a drive system with a compact footprint that would work with the existing OEM-supplied control confi guration.

SolutionHummel Industrial Sales of Fort Lauderdale supplied an ABB regenerative drive for speed and torque control – the fi rst of its kind installed in a sugar-processing facility. It offers a compact drive, regenerative capability and exact motor sizing.

Installation time was shortened because ABB matched the existing control system from the OEM without using any relays, outside control interfaces, or PLC’s. “The ABB regenerative drive was able to power the motor and match the input power supply precisely, eliminating any additional spikes or fl uctuations,” says Chris Visage of Hummel Industrial Sales. “Because the throughput has increased, the co-op will be able to use the existing motor to the fullest, instead of dissipating much of the energy, which was the case with their prior drive.”

■

■

Benefi tThe drive provides precise and rapid motor-speed response based on exact variations of the centrifuge load. This cut the centrifuge cycle time from 44 to 32 seconds, a 20 percent improvement. Direct Torque Control (DTC) enables rapid deceleration at the end of the cycle, saving valuable seconds in unload and reload operations. Additional time and energy savings are realized, as the energy from the spinning centrifuge, which turns the motor into a generator, is recovered and transferred via the drive to an adjacent centrifuge. The ABB drive’s small footprint also results in space savings of 40 percent.

Whereas the previous unit failed at least once a year, costing thousands of dollars in replacement parts and crippling the production line, the new drive is highly reliable. Reliability was important in addition to a drive that could re-capture the power lost when the centrifuge recycled.
