What are the advantages and features of microwave drying equipment?

Any drying method has its own advantages and disadvantages. Compared to conventional heating drying methods, microwave drying technology has always had unparalleled advantages. However, does this drying method also have disadvantages? Boda Microwave analyzes the characteristics of microwave drying and unravels the mysteries of its advantages and disadvantages.

1. Uniform heating refers to the simultaneous heating of materials from the inside out. The temperature difference between the inside and outside of the materials is very small, which does not cause inconsistent heating between the inside and outside during conventional heating, resulting in a puffing effect that is beneficial for crushing and greatly improving the drying quality.

2. Small size, convenient installation and maintenance, without occupying too much space.

3. When steam is used for heating, it needs to be heated from the inside to the outside. The slow heating speed requires a lot of coal. However, this equipment uses electromagnetic wave heating, which does not need heat transfer media, and directly heats to the inside of the object. The heating speed is fast. The 1 kW microwave energy can heat Water heating at normal temperature to 100 ℃ within 3-5 minutes, avoiding the above shortcomings. Therefore, the speed is fast, the efficiency is high, the drying cycle is greatly shortened, and the energy consumption is reduced. Compared with conventional drying techniques, it can improve work efficiency by more than four times.

4. Good quality, microwave drying equipment can extend the shelf life of food, preserve the original flavor and nutritional components of food, retain the activity of raw materials, enhance the functionality of health food, and increase the added value of agricultural products. Compared with conventional methods, the quality of the processed products has significantly improved.

5. Easy to control, convenient for continuous production and automation. Due to the characteristics of fast adjustment of microwave power and no inertia, it is easy to control in real-time and can adjust the temperature arbitrarily between 40 ℃ and 100 ℃.

6. This equipment has significant economic benefits, as traditional drying requires a long time, slow speed, high energy consumption, and high processing costs. Using microwave heating can save a lot of energy and improve the heating and drying speed. This is because microwaves have penetrability and do not require any media when heating objects, and can simultaneously heat both inside and outside the material. According to domestic and foreign data, using microwave equipment to heat materials has a speed and efficiency that is 4-20 times higher than conventional heating methods.

7. Microwave drying has both thermal and biological effects, and can sterilize and prevent mold at lower temperatures. Due to fast drying speed and short time, it can maximally preserve the activity of materials, vitamins, original colors and nutrients in food.

8. Safe and harmless

Due to the fact that microwave energy is controlled to operate in metal made drying rooms and waveguides, there is minimal microwave leakage, no radiation hazards or harmful gas emissions, no waste heat or dust pollution, and neither does it pollute food nor the environment.
