3.What are the Advantages of Microwave Drying?
1, uniform and thorough: high water content of the part, absorb more microwave, generate more heat, and vice versa, the less; at the same time, the product is heated inside and outside the whole, no thermal inertia, no heat transfer loss, fast drying speed. The microwave directly penetrates the product, radicalizes the water molecules, generates heat, the internal temperature is also slightly higher than the external temperature, can try to avoid the temperature gradient and produce "shell" and slow evaporation of moisture shortcomings.
2, simple control: because the microwave power can be quickly adjusted and no inertia characteristics, combined with PLC automatic control system in a timely manner, easy to adjust the process parameters and determine.
3、Improve the quality: dry in a low temperature oxygen-free environment, to better ensure the quality of the product.
4、Keep the original colour: Due to the short drying time of microwave, it solves the problem of long traditional drying time and high humidity which easily lead to the change of colour of the products, especially for precious herbs, Chinese medicine extracts, seafood products, etc. It is an ideal drying method.
5, energy saving and environmental protection: compared with conventional electric heating and drying methods, microwave drying can generally save points 50%, the equipment uses microwave radiation energy transfer, is the overall heating of the medium. No other heat transfer medium is required. Avoid the disadvantages of slow heat transfer under vacuum conditions, so the speed is fast, high efficiency, drying cycle is greatly shortened, energy consumption is reduced. There is no noise, no toxic gas or liquid emissions, and it is an environmentally friendly drying technology.
4. Which Drying Method is the Best?
The common drying methods include natural drying, boiling, drying, spray drying, freeze drying, etc. With the development and supply of the social level, some new drying technology and equipment are slowly developed and researched, microwave drying technology is the best drying method nowadays.
Traditional drying technology has more or less disadvantages and shortcomings, microwave drying technology from the theoretical point of view, can solve all the drying requirements, its emergence has solved many drying problems, such as small moisture drying, viscous material drying, embryo, making pieces of drying, filter cake drying, uniform drying, deep drying, fast drying, energy-saving drying and a series of high requirements of drying.
5. Why is Microwave Drying So Efficient?
Microwave drying and sterilisation equipment is the result of the combined effect of the thermal and biological effects of the electromagnetic field.
Microwave has the ability to penetrate and heat the medium inside and outside at the same time, without the need for heat conduction, so the heating speed is very fast, for moisture content of less than 30% of the food, the drying speed can be reduced by hundreds of times.
6. How does Moisture Content Affect Microwave Heating?
Generally speaking, the amount of moisture content in food affects the heating effect of the microwave oven. Food with a high moisture content will heat up faster.
Microwaves are actually just a mechanism for converting electrical energy into shortwave energy. It selectively targets the water molecules in the food, causing them to vibrate and release heat quickly.
7. How Microwave Drying Machine Works
The microwave drying machine works by first generating microwaves from a microwave generator and then sending the material through a conveyor system to a heater where the water in the material is heated up and evaporated by the microwave energy and the water vapour is removed through a dehumidification system to achieve drying.
The bacteria in the material are killed by the biological and thermal effects of the microwave electromagnetic field. As the microwave is directly on the material, so the drying temperature is low, fast and the loss of the active ingredients in the drug is very small.
8. Can you microwave powder?
If you want a microwave powder, make sure that the substance is not electrically conductive, that it is insulating, and that it does not burn or evaporate when heated, as this can be dangerous.

10. How to dry wood in a microwave
The main principle of drying wood in a microwave is that by increasing the temperature of the wood, the moisture in the wood evaporates and moves outwards in the air at a certain flow rate, causing the moisture to leave the wood quickly.
Microwave drying equipment allows the wood to be placed in a microwave electromagnetic field, where the electromagnetic losses caused by the interaction between the microwaves and the moisture in the wood are converted into heat energy to heat the wood.
During the drying process, the moisture content of the wood has the characteristic of being high inside and low outside, so its absorption of microwave energy gradually decreases from the inside to the outside, thus making the wood have the same temperature gradient and moisture content gradient inside. When microwave drying, as long as the wood is in the microwave penetration range, the wood is heated inside and outside at the same time, so that a fast and uniform drying effect can be achieved.
11. Microwave Drying Machine Process
Microwave drying equipment mainly uses microwave technology to dry a variety of materials, microwave is a very strong penetrating wave, can be directly on the inside of the material, the internal and external heating at the same time, the material can achieve rapid and uniform drying. The maximum temperature of microwave drying equipment can reach 200°C, while the drying time can be effectively reduced from the previous unit of "days" to "hours", the specific drying temperature and drying time depends on the type of material to be dried. The exact drying temperature and time depends on the type of material to be dried.
12. How to Troubleshoot Microwave Drying Machine
1. Raw materials on fire: raw materials cannot be sucked away, resulting in the dryer catching fire, the main reason may be that the microwave drying equipment power is too small, unable to achieve the drying effect, forced to heat, resulting in raw materials on fire.
2. Materials can not be thoroughly dried at one time: microwave dryer is too small, too much material material in the microwave dryer, or because the operator of the microwave drying equipment operator error, incorrect use of microwave dryer and lead to.
3. Uneven drying of materials: may be due to improper use of microwave drying equipment or material caking under the influence of low temperature. For the former, the operator's skills training must be strengthened so that they can master the operating skills. For the latter, the material should be crushed before drying.
13. Limitation of Microwave Drying Machine
1. High cost: Generally speaking, the investment cost of microwave drying equipment is relatively large, for some large materials is obviously not cost-effective, can not achieve a large number of drying.
2. Uneven heating: In the drying process, the mutual interference between microwaves and the reflective effect of the inner wall of the drying equipment cavity makes the energy density distribution in the electromagnetic field space different, resulting in uneven heating of the material, easy to damage the material material structure. In the later stages of drying, the material will also be carbonised due to local overheating.
14. What is loss on drying?
In the process of drying materials using microwave drying equipment, the water in the material will be evaporated and the weight of the material will be reduced, so the drying loss refers to the weight loss, caused by the water and any kind of volatile substances that can be volatile under certain conditions, which is inevitable in the drying process.
It is worth noting that microwave drying equipment can be customised in terms of drying time and temperature to achieve the desired end product, while retaining most of the nutrients in the raw material, without destroying the nutritional content of the raw material.
15. Supporting equipment to buy with microwave drying equipment
Microwave drying equipment is a very high use rate of equipment, especially in the food processing industry is very widely used, can provide manufacturers with very high drying efficiency and drying quality, dried materials rich in nutrients, high quality.
Today's microwave drying equipment has been fully automated production method, if manufacturers want to further improve the production process, you can use the feeder, conveyor, cooler and packaging machine and other equipment to further improve the drying quality of materials.
16. How to Dry Leaves in Microwave?
Place the leaves to be dried on a tray and place them in the microwave oven for about 30 seconds on a medium heat. Be careful not to dry the leaves for too long at one time or at too high a temperature, as this may cause the leaves to lose too much moisture and catch fire.
