With the development of production technology, more and more drying equipments have emerged, and artificially controllable heat sources and mechanical ventilation and dehumidification methods have gradually replaced ancient methods and their effects have become increasingly prominent. Divided according to the operating pressure of the equipment can be divided into: atmospheric pressure type and vacuum type two types of equipment drying equipment. This article will focus on analyzing the development of vacuum drying equipment. What is vacuum drying equipment? Vacuum drying equipment is designed to dry heat-sensitive, easily decomposable and easily oxidized materials. It can be filled with inert gas. In particular, some of the components with complex composition can also be quickly dried. Low oxygen content when drying under low pressure can prevent oxidation and deterioration of the material to be dried. It can dry dangerous materials that are flammable and explosive. It can vaporize the moisture in materials at low temperature, and it is easy to dry heat-sensitive materials. It can recover the materials in the dried materials. Valuable and useful ingredients; can prevent the release of toxic and hazardous substances from the dried material and can be an environmentally friendly type of "green" drying. China's drying equipment development process The first continuous vacuum freeze-drying equipment made in China was successfully developed by Shenyang Refrigeration Technology Institute in 2000. The vacuum chamber adopts a rectangular structure. There is a spacer between the in-out silo and the drying chamber. The in-out silo is provided with an automatic weighing system, which can determine the drying rate, the amount of water output and the final drying degree of the freeze-dried food. Two external water traps work alternately to achieve continuous catching and melting. After more than ten years of development, at present, China's drying equipment industry has begun to enter a more mature stage, can better meet the actual needs of users in various fields, in view of the "green" advantages of vacuum drying equipment, applications are increasingly widespread. In terms of food and drug drying, the demand for vacuum drying equipment of larger specifications will gradually increase, and the market prospect is very large. However, on an overall level, the development of vacuum drying equipment is relatively slow, and the technical level and concept of use are relatively backward. Vacuum drying equipment development is not balanced In the drying of crops, the continuous vacuum drying equipment plays an important role, but the amount of dried grain is large. Continuous drying equipment must be used. The cost of vacuum drying is too high. Therefore, the frequency of vacuum drying equipment used in agriculture Not high. In the field of food drying, food materials are abundant, and the production of freeze-dried products is large. Continuous freeze-dried food equipment appears earlier than vacuum drying equipment. Danish ATLAS Corporation produced CONRADTM 800 continuous freeze-drying equipment in 1985. For freeze-dried coffee production, it also means that vacuum drying equipment has no advantage over time. As can be seen from the above, the development of vacuum drying equipment is not balanced, especially for domestic products in China, it is more necessary to strengthen research and development in technology, but also to expand the promotion of products, so that consumers understand and in-depth understanding of the product, let it The use can be more comprehensive. Have you seen all the inflatable toys that people launch around Christmas every year? Christmas inflatable toys are one of the most popular and beautiful ways. You can use them to decorate your lawn to show your Christmas spirit.
