MAGNETIC DRIVENONION PEELERTYPE OP-120

The Magnetic Driven Onion Peeler operates as follows:

- The onions are fed into the hopper and are trans-

ported up via adjustable fingers. A wiper system

assures that onions are singulated before they are

positioned in cups which move into the peeling

section.

- An operator has to position the onion horizontally

in the cup, after which the onion is topped and

tailed via the topand tail knives that dynamically

follow the shape of the onion. As the onion moves

through the peeling section it is kept in the cup via

an adjustable pressure system.

- An incision cutting mechanism makes a horizontal

incision at the back and at the front of the onion to

ease the removal of the outer skin of the onion.

The depth of the cutting can be set to cut one or

morelayers depending on the required quality.

After the horizontal incisions have been made the

Magnetic Driven peeling wheel takes the onion off

the cup and rotates the onion, completely frictionless,

in a double horizontal Magnetic Driven onion holder.

All rotating, clamping and opening actions of the

Magnetic Driven peeling wheel occur completely

frictionless, based on magnetism, without springs,

belts or other components.

The technology used in nowadays fruit- andvegetable processing machinery is based on classic mechanics. Motion and action inside the machine is achieved by springs, friction drive belts, and other moving components.

All causing wear and requiring frequent maintenance. FTNON Dofra has applied a technologyusing permanent super magnetism, eliminating the use of wires, tubes, belts and springs resulting in a machine running with frictionless components, tremendously reducing the costs of maintenance.

Product description

NEW

While rotating the onion around its own axes, another

incision is made around the entire circumference of

the onion. The incision depth can be regulated so

that either one or more layers can be cut.

A directed jet of air, limiting the air consumption,

blows the cut skins from the onions. The waste is

transported to a waste hopper via a funnel.

The out-feed of the peeler has an adjustable

centrifugal fan, which keeps the loose skins in the

machine and separates them from the peeled onions.

Economic impact

Characteristics in shortThe Magnetic Driven onion peeler has a significant

positive impact on the following cost factors that

determine the economic return of an onion peeler

in his process:

- The yield of the onion peeling process is higher

(up to 90% reduction of onions lost during peeling

due to centrifugal forces in the conventional

peeling process).

- The human labor costs for daily cleaning and

periodical maintenance are less since the Magnetic

Driven peeling wheel consists of far less components

and is thus much easier to clean and requires far

less time to maintain.

- The onions to be peeled can have a far wider

range in diameter without having to adjust the

machine’s setting due to the better processing

control of the Magnetic Driven peeling wheel.

Less time for machine setting, less time for onion

grading results in a higher economical return.

- Components moving with friction (belts, springs,

arms etc.) are replaced by frictionless operating

super magnets which highly increase the reliability

of the machine and give a longer “up time”.

- Machine components are placed with more space

between them, in a more open con-struction,

greatly improving the hygiene of the machine and

the ease and effectiveness of cleaning.

InnovationThe uniqueness of this product lays in the application

of a technology that is completely new. Because of

the application of this new technology machines

can be build and maintained easier with less compo-

nents, are more hygienic because of less components

that are easier accessible, are more sustainable since

permanent super magnets do not wear and run

without friction and the technology is used to replace

components that do wear (springs, belts, moving

components

John de Groot, CEO of FTNON Dofra“We realized that if we wanted to offer our clients a good solution to the inconveniences of today’s machines, we had to look at machine engineering from a complete different perspective. Avoid springs that can break, avoid metal arms that can tear, avoid belts that can stretch, avoid friction that causes wear, reduce the number of components to increase hygiene and make maintenance easier.Quite a challenge. But we have realized huge improvement on all these issues via the application of atechnology using super magnetism. It took us three years of dedicated research and development which was subsidized by the European union. The results are impressive.”

TechnologyFTNON Dofra has developed and applied a

technique using permanent super magnets. Using

this technology Dofra is able to position, rotate,

clamp and release onions in a machine environment,

based on the physical position of the onion in the

machine. Frictionless!! The machine is equipped with

various kinds of super magnets which were researched

by Dofra for a period of three years under subsidy of

the European community. The related technology

of applied super magnetism in food processing

machinery is patented worldwide by FTNON Dofra.

QualityIn the same workspace as before, productivity is

increased by 50% as the capacity of the machine

increased by 50% due to the applied super magnets.

The super magnets that are applied in the onion

holders have been constructed in such manner that

big onions do not get crushed and smaller onions

do not get lost, without leaving deep (holding)

marks in the onion.

The onion that leaves the Magnetic Driven onion

peeler has an identical quality as a hand peeled

onion. For quality aspects on maintenance and

hygiene see Productivity.

ProductivityThe Magnetic Driven peeling wheel works with

6 onion holders compared to 4 onion holders in

conventional onion peelers, increasing the peeling

capacity with 50%. The Magnetic Driven peeling

wheel moves with more onion holders at a lower

rotational speed. This results in a better control of

the onion peeling process with up to a stunning

90% reduction of onions that are lost during the

peeling due to centrifugal forces in the conventional

peeling process. The conventional peeling wheel

in an onion peeler consists of some 600 parts.

The Magnetic Driven peeling wheel consists of

around 150 components. This greatly reduces the

complexity of maintenance and thus the costs of

maintenance. As the construction of the Magnetic

Onion peeling wheel is an open construction with

rounded components and without the conventional

springs and belts it is far more hygienic and easier

and faster to clean.

SustainabilityAll components that move and have friction, such as

friction belts, springs, arms moving on a curve disk,

have wear and require periodical replacement, using

up the earth’s resources. The permanent super

magnets used by FTNON Dofra have a permanent

magnetic field, with no loss of strength, no wear.

The clamps are driven by magnets, opening and

closing the clamps completely frictionless, thus no

wear. The rotation of the onion in the onion clamp

holder is done by magnets, without physical contact,

thus completely frictionless with no wear. If ever a

technology excels in sustainability, it is the super

magnetism technology patented worldwide

by FTNON Dofra.
