Гранулы через дозирующий диск (вместо блока загрузки порошка):
Гранулы под действием тяготения опускаются в дозирующее отверстие. При изменении стадии гранулы не изменяются до тех пор пока не наполнится дозирующая ёмкость. Потом дозирующая ёмкость закрывается. Когда блок с капсулой становится для обмена, открывается заслонка и гранулы поршнем уплотняют в капсулы.
Характеристики системы: 140 ударов/мин

Atmospheric freeze-drying with
active hydrodynamics
… is alternative process to classical vacuum freeze-
drying
The process has two stages: • the initial freezing at spraying of the solution• the sublimation of frozen particles at their fluidization
The initial freezing is done in a freezing cabinet, which is equipped with an ultrasonic nozzle that is capable of producing particles of 150 mm. The freezing temperature inside the cabinet was held at –60C. The 15% aqueous solution of mannitol is sprayed top-down against a cold air stream.
At sublimation drying stage of the process the frozen particles are held by fluidization, and this was performed in the modified Glatt apparatus. The process was carried out at a drying temperature of about -20ºC. The average time of the process was about 3 hours.
The main stages and description of the process
• intensive heat and mass transfer, high moisture removal rate due to active hydrodynamic regime
• reduced time of the process
• energy effectiveness in comparison with classical freeze drying under vacuum
• better control of the residual moisture content and temperature, important for pharmaceutical products
• product size and shape design for manufacturing of solid dosage forms and production of injection and inhalation dosage form
• possibility of continuous operation
The advantages of the atmospheric freeze drying with active hydrodynamics
The properties of the pharmaceutical products
• preserved of natural structure and nutrients
• pre-specified particle size (nano- or microparticles)
• high porosity
• high specific and internal surface area of particles
• solubility and bioavailability
• free flowing powder
• spherical particle shape
• …

Atmospheric Spray Freeze Drying as an Alternative
Advantages:
The result is a highly porous free flowing powder (pellets) with instant solubility properties.
The high porosity of the pellets (up to 85%) and the nanostructured internal surface is ideal for the formulation of novel drug delivery systems for the lung.
Atmospheric Spray Freeze Drying as an Alternative
Advantages:
Process is faster due to the better heat transfer and has a lower variability.
It is possible to combine the advantages of Nano- and Microtechnology.
Atmospheric Spray Freeze Drying as an Alternative
Advantages:
ideal for the preparation of nanocomposite pellets for low water soluble drugs to enhance bioavailability of the drug.
ideal for the formulation of temperature and structure sensitive drugs such as Biologicals i.e. Pharmaproteins such as Interferons, Insulin.

The drying kinetics
The driving force of process:
The drying rate: J = ∙X
The effective mass transfer coefficient: = Nu∙D/l
1 > 2 V
The main influencing factor on the value of the driving force of atmospheric freeze drying is the flow of injected heat into the product, and outflow of water at sublimation.

The mathematical model solution
• The solution of equations system allowed to investigate the hydrodynamic and temperature regimes (gas and particle velocities, temperature, void volume etc.), heat and mass transfer in any point of the apparatus, as well as to determine the drying rate.
• Moreover, on the basis of the mathematical model it is possible to find parameters for stable operation of a dryer, for example the height of a fountain.
