Beef, chicken, pork and other meat sauces prepared by high-temperature biological enzyme reaction, etc., have high nutritional value and are easily digested and absorbed by humans. This meat sauce usually needs to be dried at a low temperature to ensure its unique flavor and traditional drying method. It requires a high temperature and a long time, so that the dried meat sauce has a large loss of flavor, thereby reducing its value.
Vacuum microwave low-temperature drying has the characteristics of fast drying speed, generally completed in 1 hour, low energy consumption and large output.
Vacuum microwave drying equipment is a comprehensive high-tech drying equipment combining microwave energy application technology and vacuum drying technology. It solves the problem of uniform drying of materials under static condition. The equipment has high safety and stability and is dry. Low temperature, high quality, short time, high efficiency, high yield, low cost, etc. It is a high quality, fast low temperature drying equipment.
The evaporation temperature of the water during the drying process is directly related to the atmospheric pressure. The lower the boiling point of the atmospheric pressure, the boiling temperature of the water is 100 degrees at one atmosphere, and the boiling point of the water is reduced to 30 when the vacuum is less than -0.08 MPA. -40 degree. Therefore, under vacuum, the material can be dried quickly at lower temperatures.
Conventional heating is carried out by conduction, convection and radiation. Under vacuum, air convection is difficult to carry out. Only by conduction to provide heat to the material, the surface of the dried paste material is dried and hardened to form a "solid" outer casing, external The heat is difficult to enter, and the internal moisture is difficult to discharge. Therefore, the drying speed is slow. The benefit is low. The cycle is long. The temperature is not easy to control and directly affects the dry quality of the material.
Vacuum microwave drying is the use of microwave energy to heat the material under vacuum. In the microwave field, the material absorbs microwave energy and generates self-generated heat. The heating speed is fast, the heat energy distribution is uniform, the heat energy utilization rate is high, and the water is quickly discharged. At the same time, The transmission of microwave energy in the vacuum state will not be affected, the material can be quickly heated by the microwave as a whole, without loss of energy, the material will not form a hard outer shell during the drying process, and the gas during drying is easy to discharge and the drying temperature is low. The speed is fast. The quality is high. The active ingredients of the medicine can be more retained.
Vacuum microwave drying is the overall heating of the material, the drying process and the quality controllability are strong, changing the traditional way to calculate the drying amount by the paving area, and directly calculating the drying yield of the equipment by the loading amount. therefore. The vacuum microwave drying equipment has completely changed the traditional drying technology. It not only has low temperature, fast and uniform drying characteristics, but also has high controllability. It can greatly improve the quality, save energy by 80%, and the drying speed is ten times faster. The rate is almost 100%, no reduction in environmental pollution, greatly improving the economic efficiency of enterprises, and becoming an advanced modern drying equipment.
