Microwave Drying & Sterilizing Equipment

Main 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 sterilizing and oral liquor, pickles, a variety of small packaging food; and for thawing the frozen fish, poultry; and for drying beans; and for drying and desulfurating and deoxidizing the metallurgical chemical products; such as oxalate cobalt, sulfur powder, mid-ammonium tungstate, nickel hydroxide, bluestone, iron core, magnetic core and magnetic resonance organ, magnetic boards, disk, alveolate ceramic, plaster 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.

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 molecule.so 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.

The principle of microwave sterilizing

Microwave sterilizing is the result of combined action of the thermal effect of electromagnetic fields and the biological effect.Thermal effect of microwave on the bacteria denatures the protein of bacteria ,and make the bacteria lost the condition of nutrition,reproduction and survival so as to die .The biological effects of microwave on the bacteria is that the microwave electric field changes the potential distribution of cross-section of the bacterial cell membrane and impacts the concentration of electron and ion around the membrane ,and changes the permeability of cell membranes ,therefore the bacterium become innutrient and lost normal metabolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,as a result they are dead.Moreover ,nucleic acid genetic(RNA) and deoxyribose acid (DNA),which decide the normal growth and stability of bacterial,are curly-shaped macromolecule made of a number of linked compactly hydrogen bond .The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome aberration and even rupture.

  1. Main features of microwave drying&sterilization equipment

Microwave drying is totally different from conventional heating method. Microwave drying does not need the process of heat conduction, which make the material itself become a heating unit. Therefore, the materials of poorer heat conduction can also be to reach the heating temperature in a very short period.

  1. Symmetrical drying
  2. No matter what the shape of each part of objects is, microwave drying is the object that make the electromagnetic waves infiltrate to the exterior and interior of the material symmetrically at the same time to produce heat energy. Because of no restrictions on the shape of the material, the materials is heated even, and there is no adjust outside or unheated inside.
  3. Energy saving and efficient
  4. The material containing water is easy to absorb microwave heat, therefore, there is no other heat loss besides a small amount of transmission loss. So there are higher thermal efficiency and more energy saving. The microwave heating can save one third energy of the far-infrared heating.

  1. Mildew proofing/sterilizing/keeping fresh

Microwave heating with thermal and biological effects can sterilize and resist rot under lower temperatures. As the heating speed is faster and the process time is shorter, the microwave heating can reserve furthest the activity and vitamin in material, and the original color and the nutritional ingredient.

  1. Advanced craftwork and control
  2. By controlling the microwave power, you an realize heating and termination immediately; With the use of graphic operation terminal and PLC, you can realize programmable auto control of heating process.
  3. Safety and innocuity

The microwave work in the heating-room and the waveguide pipe made of metal, which can prevent the leakage of the microwave. There is no harmful radioactivity of harmful gas, or waste heat or dust pollution, so neither could microwave heating contaminate food nor pollute the environment.
