Freeze dryer details to customers.pdf
Freeze dryer is also called freeze dryer. A freeze dryer is a freeze-drying device that first freezes water-containing substances into a solid state, and then sublimates the water in it from a solid state to a gaseous state to remove moisture and preserve the substance. The vacuum freeze-drying technology used by the freeze dryer has a wide range of applications in the fields of bioengineering, pharmaceutical industry, material science and deep processing of agricultural and sideline products.
Especially for the mini household freeze dryer, the applicable materials are: vegetables, fruits, dairy products, etc., which makes the freeze dryer more widely applicable.

The freeze dryer has many uses and a wide range of applications, so there are quite a few types of freeze dryers. Freeze dryers are mainly divided into: medical freeze dryers, food freeze dryers and experimental freeze dryers according to their uses.
Pharmaceutical freeze-drying has been developed to a certain extent, and many larger pharmaceutical factories have freeze-drying equipment. In terms of injections, freeze-drying technology is widely used, which improves the quality and storage period of medicines, and brings benefits to both doctors and patients. There are not many varieties of freeze-dried drugs, the product price is high, and the drying process is not advanced.
Food freeze dryers utilize the basic principle of freeze drying which is based on the three-state change of water. Under the high vacuum state, using the principle of sublimation, the water in the pre-frozen material can be directly sublimated into water vapor in the ice state without melting the ice, so as to achieve the purpose of freeze drying. Vacuum freeze-drying can be performed on solid, liquid and other substances. Because the drying process has been carried out under low temperature and vacuum state, the body shape, color and nutritional content of the original food substance can be kept basically unchanged after the freeze-drying process.
Laboratory freeze dryers are divided into bell type freeze dryers, small in-situ freeze dryers, etc. according to the development, among which bell type freeze dryers are divided into: ordinary type, gland type, multi-manifold type and multi-manifold pressure type. cover type. The in-situ pre-freeze dryer is an upgraded freeze-drying machine based on the bell-type freeze-drying machine. It has the functions of in-situ pre-freezing, process setting and modification, data recording and storage, and freeze-drying curve. It is an experimental freeze-drying process. Developed freeze dryer. Usually the amount of freeze-dried materials in the laboratory is relatively small, so the design of laboratory vacuum freeze-drying machines is designed and produced according to small size. Compared with conventional methods, laboratory lyophilizers have the following advantages: Many heat-sensitive substances will not be denatured or inactivated. Laboratory freeze dryers have been widely used in environmental protection testing and scientific research, and play a very key role in the analysis and detection of environmental protection samples. At the same time, the small laboratory freeze-drying machine is also suitable for freeze-drying experiments of biological samples, freeze-drying experiments of industrial materials, freeze-drying experiments of fine chemical samples, and rare earth freeze-drying scientific research.
Freeze-drying is a drying technology using the principle of sublimation. It is a process in which the dried material is quickly frozen at low temperature, and then the frozen water molecules are directly sublimated into water vapor in a suitable vacuum environment.
The freeze dryer first freezes the dried items below the triple point temperature, and then directly sublimates the solid water (ice) in the items into water vapor under vacuum conditions, and removes them from the items to dry the items. The equipment adopts high-efficiency radiation heating, and the material is heated evenly; it adopts high-efficiency water-trapping cold trap, which can realize rapid defrosting; adopts high-efficiency vacuum unit, which can realize oil-water separation; adopts parallel centralized refrigeration system, multi-channel on-demand cooling, working conditions It is stable and beneficial to energy saving; artificial intelligence control is adopted, with high control precision and convenient operation.
The freeze dryer is composed of a vacuum system, a refrigeration system, an electrical instrument control system, and a heating system. The main components are condenser, vacuum pump, heating/cooling device, drying box, refrigeration unit, etc.
