Industrial Microwave Freeze Dryer Machine
Industrial microwave freeze dryer machine is an emerging microwave freeze dryer machine. When drying, the microwave energy directly acts on the medium molecules to convert into heat energy, and the microwave itself has strong penetrability. The dried objects can be heated simultaneously inside and outside, so when using microwave heating, there is no external ripening. In the case of life, heat conduction is not required, so the heating rate is very fast, and regardless of the shape of the object to be heated, the microwave is extremely strong, and the temperature inside and outside of the object to be heated is almost uniform, and the heating is uniform, which greatly improves. Dry quality and dewatering effect.
The microwave itself is not hot, and the electromagnetic energy absorbed by the object is converted into heat energy, so that the heating object itself becomes a heating element. Heat conduction, convection heat transfer, and infrared radiation heating are three conventional heating methods. Conduction is one of the most used in our daily life. We often use heat conduction in our daily life. The heat is used to contact the surface of the heated object with a heat-absorbing metal as a medium to form heat conduction. Convection is the conduction between fluids. In the life, boiling water with a kettle is the realization of convection. When the water is opened, the convection of hot water and cold water can be seen. Radiation and thermal radiation are also a way of heat transfer. Thermal radiation must have a higher temperature heat source to transfer heat between the object and the object, such as me. When we stand next to the heater, we can feel the burning sensation to the body, which is to use heat radiation to heat.
The microwave heating is to heat the heated object by electromagnetic, so that compared with the conventional heating method, not only the heating time is short, but also the external factor is not needed to heat the object, and the microwave heating does not need to be preheated, and the microwave heating speed itself Quickly, this aspect is directly omitted in the preheating process, which not only ensures the taste of the food, but also reduces the loss of nutrients in the food itself, which is more suitable for the processing of some high temperature resistant foods.
With the continuous development of society, China's industry and agriculture are also making progress, and microwave drying technology is becoming more and more mature, in the process of industrial and agricultural development. Also played an indispensable role. The advantage of microwave drying technology is that microwave drying greatly reduces the heating time compared with the traditional drying method, and the microwave has strong penetrability and higher thermal efficiency. For this reason, microwave drying can evenly heat the dried object. . Not only that, the microwave sterilization ability is stronger, meets the requirements of modern food hygiene, and the time is short, no professional operation is required, and the labor intensity of workers can be reduced, and it is more suitable for mass production of food processing plants. For example, in real life, seasoning manufacturers and manufacturers of ceramics have integrated microwave drying technology into actual production.
Microwave drying technology is now relatively mature. In the food industry, the maturity of microwave drying technology has solved the problems in the food industry. The application of microwave drying technology in the food industry has achieved remarkable results. The importance of drying equipment in China has also increased. The variety of drying equipment has increased. The more diversified, the wider the scope of application, the quality of products has been greatly improved, directly affecting people's lives, and constantly improve people's quality of life, and researchers of microwave technology should always pay attention to the development of microwave drying technology. In the process of development, we must also find problems in time and make changes to strive to improve the application of microwave drying technology in the food industry, continuously improve the production level of the food industry, and upgrade our country's food industry to a New height.
