SPRAY TYPE
FREEZE-DRYING EQUIPMENT
The SEIES company produces spray-type freeze-drying equipment for the lyophilization of berries, fruits, vegetables and other food products (dairy, meat, fish products)
Case manufacturing options:
Polymer composite, the inner surface of the chamber is made of stainless steel AISI 304
Completely made of stainless steel
Painted steel
Equipment with infrared heating is available with the following loading volumes:
250, 500, 750 уstandard kg of raw materials*
Depending on the humidity and type of raw material, fraction and temperature, the time for direct lyophilization ranges from 8 to 36 hours.
Drying cycle - approximate 1 day
*Фактический объём загрузки может отличаться, так как зависит от влажности и фракции загружаемого сырья. Под объемом загрузки подразумеваются два параметра - льдоёмкость десублиматора (т.е. десублиматор может на себя вобрать 500, 700 и т.д. литров льда) и площадь полок для сырья из расчета 10 кг на кв.м. (площадь полок составит 50 и 75 кв.м. для объема загрузки 500, 750 кг).

TECHNOLOGICAL CHAIN FOR LIQUID PRODUCTS LYOPHILIZATION
For contact type equipment
Preparing the liquid

Pouring liquid onto trays.
Typically produced by humans,
resulting in reduced purity levels

The liquid is supplied into the chamber automatically by a pump
3
Freezing liquids on trays.
The time depends on the thickness of the layer.
Trays are deformed due to an increase in the volume of liquid during freezing, which leads to a sharp decrease in heat transfer and, as a result, an increase in drying time

Freezing as a separate stage is not required - evaporative freezing occurs inside the chamber in a vacuum at injection speed, no additional time is required

Lyophilization
The time depends on the thickness of the layer. When the layer thickness is more than 5 mm, local high-pressure zones with water in the liquid phase appear - this reduces the quality of the resulting product

Lyophilization
Time is minimal and predictable, because product granule size does not exceed 500 microns

Collection of freeze-dried product from trays is usually done manually with spatulas, which leads to a decrease in the level of cleanliness
The finished product is automatically fed into the receiving hopper
6
Grinding of freeze-dried product. The finished product requires grinding - bringing it to a homogeneous fraction
No grinding is required - the freeze-dried product is a scattering of spherical granules of approximately homogeneous fraction
7
Packaging of the finished product
