Chili Powder Microwave Sterilization Machine


1. The principle of microwave drying

Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.    

2. The principle of microwave sterilization

The Microwave Sterilization is the result of the role of the microwave thermal effects and biological effects. Affect the membrane around the electron and ion concentration microwave distribution of the cross-section of potential bacterial membrane permeability of the cell membrane, thus changing the energy, bacteria, therefore malnutrition can not be normal metabolism, growth and development hampered by death. From a biochemical perspective, the normal growth and reproduction of bacteria nucleic acid (RNA) and deoxyribonucleic acid (DNA) is closely connected to the curl macromolecules by the number of hydrogen bonds, microwave cause hydrogen bonds the slack, breaking and reorganization, and induce genetic gene or chromosomal aberrations, or even broken. The Microwave Sterilization is the use of the electromagnetic field effects and biological effects play a role in the killing of microorganisms. Practice has proved that using microwave device to maintain the sterilization temperature, sterilization time, product quality, product shelf-life and energy-saving aspects have a clear advantage.


3. Application

This machine fits for drying and sterilizing powders, granular, sheet-like or gel-like food, and additive, spices, flavoring, medicine, raw material of herbal medicine, nutritional health products, agricultural & sideline products, non-fired(or oil saving)instant noodles, noodles, rice powder needles, soy products, beef jerky, preserved meat, dried fish, tea, tobacco and so on; and for drying, peeling and baking almond, peach kernel, groundnut kernels, chestnut and so on; and for puffing of leisure food, pachyrhizus chips, potato chips, dried shrimps, fish maw and so on;  and for thawing the frozen fish, poultry; and for drying beans; and for drying and desulfurating and deoxidizing the metallurgical chemical products; and for drying printing and dyeing products, ceramics, glass, chemical fiber, cotton yarn, wood, leather, bamboo products, insulation materials, building materials, wood , cork, alveolate, cardboard,corrugated cardboard, and so on.

4. Drying and Sterilizing Features

  1. Fast heating. Microwave heating is completely different with traditional heating mode. It makes heating medium become heater, do not need heat transfer process. Although thermal conductivity is poor materials, also can achieve heating temperature in a very short time.
  2. Save energy and efficiency. Because materials contain water absorb microwave easily and fever, so in addition to a small amount of transmission loss outside, almost no other loss, so high thermal efficiency, save energy.
  3. Heating even. No matter how shape of each part of the body, microwave heating all can make the object and evenly infiltration and electromagnetic wave list to produce the heat. So heating good uniformity, won’t appear the endogenous phenomenon focal.
  4. Mouldproof, sterilization, fresh. Microwave heating has thermal and biological effect, can sterilize and mould proof  in low temperature.Due to heating rapidly, the time is short, can maximum limit save material activity and the vitamin original colour and lustre and nutrition of food.
  5. Craft is advanced, control easily. Microwave heating just have the basic conditions of water, electricity, as long as control power, can realize microwave heating or terminate immediately, use microwave equipment can process automation control of heating process and heating process specification.
  6. Covers less area, safety and harmless. Because microwave can be controlled in made of metal heating indoor and wave, so microwave leak is few, no radiation hazards and harmful gases, do not produce the waste heat and dust pollution; Neither polluting food, also do not pollute the environment.


5. Drying and Sterilizing Features


  1. The equipment use advanced production technology,adopt Panasonic magnetron,long life,best effect;
  2. Adopt 304# stainless steel, compact structure,no energy dissipation,save energy;
  3. Tunnel type design,cover small area,fast drying and sterilizing speed,can continuous production;
  4. Drying and sterilizing at the same time,one equipment has many usages
