Seven Advantages of Microwave Vacuum Drying Equipment

- May 07, 2019 -

In recent years, China has taken the lead in developing vacuum microwave equipment, and through unremitting efforts, completed the development of industrial microwave vacuum drying equipment. It provides a new and efficient drying equipment for pharmaceutical engineering, biological engineering, chemical engineering, material engineering and deep processing of agricultural and sideline products.

Let's analyze the advantages of microwave vacuum drying equipment: (P>

1) High-efficiency conventional vacuum drying equipment uses steam to heat, needs to heat from inside to outside, slow heating speed needs to consume a lot of coal, and microwave vacuum drying equipment uses electromagnetic wave heating, does not need heat transfer media, directly heating to the inside of the object, heating speed. Fast, 1 kW microwave can heat water at room temperature to 100 C in 3 - 5 minutes, which avoids the shortcomings mentioned above. Therefore, it has the advantages of high speed, high efficiency, shorter drying period and lower energy consumption. Compared with conventional drying technology, it can increase work efficiency more than four times. Advantages of drying methods in industrial microwave knowledge popularization series.

2. Heating is uniform because microwave heating is used to heat the material from inside to outside at the same time. The temperature difference between inside and outside of the material is very small, and the inconsistency between inside and outside heating in conventional heating will not occur, resulting in the effect of expansion, conducive to crushing and greatly improving the drying quality.

3, easy to control, easy to continuous production and automation. Because microwave power can be adjusted quickly and without inertia, it is easy to control in real time, and can adjust the temperature arbitrarily between 40 and 100 degrees Celsius.

P>4, small spare volume, easy installation and maintenance, not occupying too much space. Microwave vacuum drying equipment is of good quality. Microwave vacuum drying equipment can prolong the shelf life of food, preserve the original flavor and nutrients of food, retain the physiological activity of raw materials, enhance the function of health food, and increase the added value of agricultural products. Compared with conventional methods, the quality of processed products has been greatly improved. Microwave vacuum drying equipment has the efficacy of disinfection and sterilization, and the product is safe and hygienic. Long shelf life.

P>7. The economic benefit of microwave vacuum drying equipment is remarkable. Traditional drying takes a long time, slow speed, high energy consumption and high processing costs. Microwave heating can save a lot of energy and improve the speed of heating and drying. This is because microwave has penetrability. When heating an object, it does not need any media, and it can heat both inside and outside the material at the same time. According to the data at home and abroad, the speed and efficiency of heating materials with microwave equipment is 4-20 times higher than that of conventional heating methods.
