The freeze-drying method is in fact a adjust in water material and its transfer process. A large volume of water made up of biological merchandise first frozen into a reliable, and then in a vacuum state solid ice immediately sublimated into h2o vapor, drinking water vapor condensate in the condenser into the frost, dry frost soon after the conclude of the discharge. In the freeze-dried box to get the essential freeze-dried products.

Freeze-dried foods will deliver you the rewards as follows:

• Maintain meals first shade, smell, taste, condition and protein, vitamins.

• natural, no preservatives, with excellent preservation capabilities.

• In the package deal in very good condition, has a very long shelf lifestyle and a corresponding shelf cycle.

• Can be stored at place temperature, removing the want for complex cold chain, which does not call for cold storage / refrigerated transportation, chilly container sales and family refrigerators.

• Food accounts for most of the weight of the drinking water has been removed, so the light-weight excess weight, straightforward to transport.

• rehydrated rapidly and effortlessly consumed.

• It will give you the ultimate high additional value and economic positive aspects.

The freeze-dried products of biological items need to have to have a particular physical kind uniform coloration, experienced residual moisture content material, very good solubility, substantial survival charge or efficiency, lengthy shelf life. Consequently, not only the seedling process and the freeze-drying following the preservation of manage. Much more importantly, the freeze-drying approach of each and every phase of the parameters of a thorough handle in buy to get substantial-quality goods. Freeze-drying curve and timing is the basic foundation for the freeze-drying method handle.
 

Pre-freezing velocity
Pre-freezing speed Most equipment can not be managed so that the rate of pre-freezing can only be identified by the pre-freezing temperature and the packing time, and the fee of pre-freezing is necessary. The freeze-drying box first drops to a decreased temperature before the item Into the box demand the fee of pre-freeze is gradual, then the product into the box soon after the freeze-drying box to amazing.
 
Pre-frozen least temperature
This temperature relies upon on the eutectic temperature of the product and the pre-freezing minimal temperature need to be lower than the eutectic temperature of the item.
 
Pre-frozen time
The quantity of the solution is massive, the container is not thick at the conclude of the container, not the item is put immediately on the freeze-drying box layer, and the freeze-drying ability of the freeze-drying box is bad, and amongst every single board layer and each board layer Portion of the machine in between the massive temperature difference, the requirements of the pre-freezing time longer. In order to freeze all the bottles of the merchandise in the box, it is usually necessary to sustain a time of 1 to 2 hrs right after the temperature of the sample reaches a predetermined minimum temperature.
 
Condenser cooling time
Condenser needs in the pre-freezing interval, the pre-freeze has not but finished, before the vacuum began to cool down. How considerably time to be determined by the cooling functionality of the condenser machine. Needs in the pre-freeze end of the vacuum when the temperature of the condenser to get to -forty ºC or so. Great equipment typically half an hour just before the beginning of cooling.
The cooling of the condenser is generally continued from the commencing right up until the conclude of the freeze. The temperature ought to often be under -40 ° C.
 
Vacuum time
Pre-freeze is the commencing of the time to start the vacuum, requiring about fifty percent an hour in the vacuum can attain 1 × 10-four mbar.
Vacuum at the exact same time, but also freeze-drying box among the vacuum valve to open up when the vacuum pump and vacuum valve open up the same till the finish of the freeze.
 
Pre-freeze the stop of the time
The pre-freezing end is the procedure of the freeze-drying box freezer, which typically stops the procedure of the freezer while evacuating or vacuuming the specified requirements.
 
CZPTt heating time
It is typically considered that the time to start off heating (in truth, the vacuum began to sublimate). The start of the heating was achieved right after the vacuum reached 1 × 10-1 mbar (near to 1 x 10-1 mm Hg). Some freeze-drying machines had been instantly turned on by means of a vacuum relay, i.e., the air degree was 1 x ten-one mbar , Some of the freeze-drying equipment is in the vacuum following half an hour to commence heating, then the vacuum has arrived at 1 × 10-1 mbar or even larger.

The overall time of freeze drying
The complete time of freeze-drying is pre-freezing time, additionally the time of sublimation and the second stage of work. The complete time is identified and the freeze-drying stop time is also decided.
This time according to the item range, the variety of bottle, packing, loading, device performance, and many others. to choose, the basic work of a long time in the cold, about eighteen-24 hours, some specific items consider a few days time.
