Industrial Dehydrator Freeze Drying Equipment Vacuum Low Temperature Dryer
Product Application:
Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process that involves freezing the product and lowering pressure, removing the ice by sublimation.
The vacuum dryer is composed of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying box, water trap (cold trap), refrigeration unit, vacuum pump, heating/cooling device, etc.
The difference between vacuum drying and freeze drying:
Vacuum drying mainly for raw products that not very heat sensitive.
Freeze drying mainly for areas where nutrition is need to preserve.
Brief description of freeze-drying process:
(1) Pretreatment process
For different materials to be dried, the pretreatment methods are different. According to the characteristics of raw materials, corresponding processing methods are adopted, such as pre-treatment of vegetable freeze-drying, in addition to sorting, cleaning and cutting of raw materials, blanching is also required. The blanched vegetables need to be cooled quickly, and after cooling and draining, they can be plated. For the pre-treatment of fruits, the main purpose is to protect the color, and the processing techniques are different.
(2) Pre-freezing process
There are two methods of pre-freezing: vacuuming, self-evaporative freezing and freezing with quick-freezing equipment. According to the nature of the material, select the pre-freezing rate. The pre-freezing process directly affects the quality of materials.
(3) Sublimation drying
Sublimation drying is carried out in a vacuum device, so it is very important to maintain a suitable vacuum during the sublimation drying process.
(4) Post-treatment process
Vacuum freeze-dried food is generally porous and loose, with a large surface area, easy to absorb moisture.
Advantages of Vacuum Freeze Drying Machine:
Freeze-drying causes less damage to the substance than other dehydration methods using higher temperatures. Nutrient factors that are sensitive to heat are lost less in the process as compared to the processes incorporating heat treatment for drying purposes.
Freeze-drying does not usually cause shrinkage or toughening of the material being dried. In addition, flavours, smells, and nutritional content generally remain unchanged, making the process popular for preserving food.
Freeze-dried products can be rehydrated (reconstituted) much more quickly and easily because the process leaves microscopic pores. The pores are created by the ice crystals that sublimate, leaving gaps or pores in their place. This is especially important when it comes to pharmaceutical uses. Freeze-drying can also be used to increase the shelf life of some pharmaceuticals for many years.
