Microwave betel nut expander | microwave betel nut dryer | microwave betel nut dryer new process characteristics, the principle of microwave heating inside and outside at the same time, in a short period of time, the information speed produces expansion effect, so that betel nut shell expansion, internal brazing dimension changes, making it soft, loose, significantly increase the taste and flavor. The granules are plump, natural in color, beautiful in appearance, and have the function of insecticide and sterilization. The characteristics of microwave extrusion baking are high energy conversion efficiency and fast heating speed. The microwave oven itself does not heat, but the microwave energy penetrates the material, causing the polar molecules in the material to friction with each other and generate internal heat. The liquid inside the processed material is instantaneously heated, vaporized, pressurized and expanded, and the macromolecule material in the component is denatured by the expansion force of gas, and becomes a multi-microporous material with network structure characteristics and stereotyping. The principle of microwave thermal effect accompanied with microwave puffing and baking. Microwave sterilization is carried out under both thermal and non-thermal effects of microwave. Compared with conventional temperature sterilization, microwave sterilization can achieve satisfactory sterilization at lower temperature and in a very short time. Generally, the sterilization temperature is about 80 C, the treatment time is 3 - 5 minutes, and the nutrient composition can be maintained to the maximum.

2), easy to use and operate. Microwave power and speed of transmission belt can be steplessly adjusted without thermal inertia. It can be switched on and off immediately, which is simple and easy to control. Improve the production environment. Microwave equipment has no waste heat radiation, no dust, no noise, no pollution, and is easy to achieve the detection standard of food hygiene. The puffing effect was obvious. The rapid heating effect of microwave makes the water molecules inside the material vaporize rapidly and achieve the purpose of expansion.

4), low temperature sterilization and less loss of nutrients.
