Two new 0.5 square meter freeze-drying machines have arrivedfreeze dryerThere are various drying methods, such as sun drying, boiling drying, drying, spray drying and vacuum drying, but common drying methods are usually carried out at temperatures above 0 ℃ or higher. The products obtained from drying generally have problems of volume reduction and texture hardening. Most of the volatile components are lost, and some heat sensitive substances undergo denaturation and deactivation. Some substances even undergo oxidation. Therefore, there is a significant difference in the characteristics of the dried product compared to before drying. The freeze-drying method is basically carried out below 0 ℃, that is, in the frozen state of the product. Only when the residual moisture content of the product is reduced in the later stage, can the product be raised to a temperature above 0 ℃, but generally not exceeding 40 ℃. Under vacuum conditions, when water vapor sublimates directly, the drug remains in the frozen ice shelf, forming a sponge like porous structure. Therefore, its volume size remains almost unchanged after drying. Before reuse, simply add injection water and it will dissolve immediately. Working principle of freeze dryer; The amount of water vapor in compressed air is determined by the temperature of the compressed air: while keeping the pressure of the compressed air basically constant, reducing the temperature of the compressed air can reduce the water vapor content in the compressed air, and excess water vapor will condense into liquid. A freeze dryer uses refrigeration technology to dry compressed air based on this principle. Therefore, the refrigerated dryer has a refrigeration system.Freeze drying (hereinafter referred to as freeze-drying) is a method of preserving substances by first freezing them into a solid state, and then sublimating the water from the solid state to a gaseous state to remove the water. Working principle of freeze dryer; The amount of water vapor in compressed air is determined by the temperature of the compressed air: while keeping the pressure of the compressed air basically constant, reducing the temperature of the compressed air can reduce the water vapor content in the compressed air, and excess water vapor will condense into liquid. A freeze dryer uses refrigeration technology to dry compressed air based on this principle. Therefore, the refrigerated dryer has a refrigeration system.The freeze dryer has a wide range of applications, high work efficiency, long service life, and many advantages. How to operate it specifically? Taking tea as an example, the process is as follows: once the tea leaves are dried, they are put into the vacuum drying chamber one by one, the drying chamber door is closed, the refrigeration is turned on, the vacuum is turned on, the oil pump is turned on, the electric heating is set, the time is set, the drying is completed, the vacuum pump is stopped, the electric heating is stopped, the oil pump is stopped, the vacuum is released, the tea leaves are defrosted, and the next round of work is carried out.Our company has a large reserve of vacuum freeze dryers, including food type freeze dryers and pharmaceutical type freeze dryers, with a complete range of models and sizes. Food type freeze dryer is suitable for vegetables, fruits, meat, fruits, flowers, tea, cat food, food, etc; The pharmaceutical vacuum freeze dryer is mainly produced by Dongfulong brand and is suitable for products such as traditional Chinese medicine, western medicine, chemical drugs, etc.The company's existing equipment is a second-hand vacuum freeze dryersecond-handfreeze dryersecond-handDongfulong Freeze Drying Machine Second hand vacuum dryersecond-handfreeze dryersecond-handDongfulong freeze dryersecond-handFood type freeze dryerVarious models are available for logistics and delivery.Freeze dryer is suitable for drying high-end raw materials, traditional Chinese medicine decoction pieces, biological and wild vegetables, dehydrated vegetables, food, fruits, chemicals, pharmaceutical intermediates and other materials. Freeze vacuum drying is a new type of box structure developed by combining the refrigeration system, vacuum system, thermal oil heating system, and dehumidification system in a vacuum freeze dryer, which greatly utilizes the storage space inside the box for freeze-drying.Vacuum freeze dryer is suitable for drying high-end raw materials, traditional Chinese medicine decoction pieces, seafood, wild vegetables, dehydrated vegetables, food, fruits, chemical drug intermediates and other materials.The vacuum freeze dryer combines the refrigeration system, vacuum system, thermal oil heating system, and dehumidification system into a new type of box structure, which greatly utilizes the storage space inside the box for freeze-drying and vacuum drying, and can make the dried powder have good dispersibility. The process of freeze-drying involves the absence of impurities mixed into the object, which can maintain the original and active components of the material and prevent damage to its shape.
