“A fat white man lives in a hemp house with red curtains.” I’m sure you’ve all guessed this riddle. Yes, the answer to this riddle says peanuts. Peanut is a kind of nut with rich yield and wide consumption in China, also known as “groundnut”, “mud bean” and so on. It is rich in nutrients, there are many ways to eat, it is also a good companion food, it’s a snack food that most people like.
The harvest season of peanuts is cloudy and rainy, so they cannot be dried in time, so they can only be piled together. If it is not dried in time, peanut is prone to mildew, which produces aflatoxin with strong carcinogenicity. In order to solve this problem, the Leader Microwave Equipment Company researched microwave drying technology, and finally developed and made peanut microwave drying equipment according to the drying characteristics of peanuts.
Advantages of peanut microwave drying equipment：
1.Simple equipment, advanced technology
Compared with the conventional drying method, peanut microwave drying equipment does not need boiler, pipeline system, coal yard and transportation vehicle, as long as it has the basic conditions of water and electricity, no special requirements on the plant, less investment, quick results, advanced technology.
2.Drying time is short and speed is fast
Conventional thermal drying and sterilization is the transfer of heat from the surface of an object to its interior by means of heat conduction, convection or radiation. It often takes a long time for the interior of the object to reach the required drying degree and sterilization temperature. However, peanut microwave drying and sterilization equipment is the dielectric material itself loss of electric field energy and heat, so the microwave heating treatment time is greatly shortened, under a certain power density intensity, generally as long as tens of seconds, a few minutes can achieve satisfactory results.
3.Dry evenly and thoroughly
Conventional thermal drying and sterilization start from the surface of the material, and then transfer to the interior of the material through heat conduction. Peanut microwave drying machine with penetrating performance, the surface and internal function at the same time, to ensure that the internal and external temperature with the required value, so drying, sterilization uniform and thorough.
4.Easy to control and easy to achieve automatic production
Peanut microwave drying treatment equipmentis simple to operate, easy to control, no thermal inertia, according to the requirements of different food technology specifications for processing, reduce production operators, reduce production costs.
5. Maintain nutrient content
Peanut microwave drying machine has thermal effect of rapid warming and non-thermal effect of double sterilization, compared with conventional thermal drying, sterilization can be in a lower temperature and a shorter time to obtain the desired drying, sterilization effect. Can retain more food nutrients and color, aroma, taste, shape and other flavors.

Working principle of peanut microwave drying equipment：
Microwaves are electromagnetic waves of frequencies from 300 MHZ to 300 Gigahertz. The dielectric material is composed of active and non-active molecules. Under the action of electromagnetic field, these active molecules change from the original random distribution to the positivity orientation of the electron field. Under the action of high-frequency electromagnetic fields, these orientations change according to the change of alternating electromagnetic fields, which causes the motion and friction effect of molecules to generate heat. At this time, the field energy of alternating electromagnetic field is transformed into the thermal kinetic energy in the medium, making the temperature of the medium rise continuously, thus achieving the drying effect.
The microwave drying equipment of peanut adopts new technology, which solves the existing problems of peanut drying, can maintain the quality of peanut well, and can also be applied to the drying of agricultural products such as tobacco, mushroom and pepper. In addition, there are scented tea microwave drying equipment, vegetable microwave drying equipment, food microwave drying equipment in the market have good development, their promotion potential is huge, and is worthy of our trust!
