The principle of microwave drying/heating
Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .
It can penetrate the inside of the material.atht is to say microwave energy can heat the matrial from insedeto outside at the same time.
The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will aLDer with the changes of the external electric field with the highspeed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in mudium to rise the temperature of materials. accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,mircrowave heating is achieved.
The principle of microwave sterilization
Mircowave sterilization is the resuLD of combined action of the thermal effect of eletromgnetic 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 lon 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 resuLD 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 hydrongen bond .
The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine , and induce intragenic mutation or chromosome aberration and even rupure.
The features of industrialred chilli spice powder microwave drying sterilization machine:
1.Fast heating speed: directly heat on the internal and external of material at the same time, do not need to preheat. While there must be a preheating process in the traditional production.
2. Heating evenly: microwave drying is completed through electromagnetic waves produced by magnetron.The internal and external of material will be heated at the same time .
3. Less nutrition loss: material just stay in the microwave heating box for a short time, and do not need air and steam to conduct heat, therefore can maximize keep nutrients in the material.
4. Sterilization and alcoholization:The microwave drying equipment also have sterilizing and alcoholizing function.
5. Reduce the labor intensity, improve work efficiency
6. Friendly environment equipment
7.PLC automatic control can realize the data storage, output, printing.
8.Using non-contact infrared temperature measurement technology, high precision, simple control.
9.Compliance with national GMP certification requirements.

About Baby Powder Sterilization:
1, It is suitable for microwave sterilization with high production efficiency.
2, Its temprature is over 100 degree.
3, Its original total numbers of colony(bacteria) is 3800 cfu/gm. and after microwave sterilization, the total numbers of colony is 50 cfu/gm.
You can send your sample to us if you feel maybe it's impossible for your material, we can test it for you about drying and sterilization for free.
Compared with conventional drying methods, which are heating from the outside to the inside by heat conduction, microwave show so-called volume heating with the following advantages:
1, temperature gradient directed towards the surface, i.e. temperatures inside are higher than outside, giving rise to a higher partial pressure that drives the evaporating liquid to the surface consequently, the superficial layer does not dry up completely and the surfaces remain permeable.
2, the liquid evaporating inside the product is emitted through the porous structure of the solid material’s macro-capillary system, resuLDing in a high drying velocity.
3, the heating of water and most organic solvents occurs selectively - due to the LDer dielectric losses of water as compared to the product to be dried.
4, LDift and thorough drying of moist products with low thermal conductivity static drying of thick layers without frictional losses.
5, high total efficiency of energy application and high-speed control of the energy transport.
6,short processing times, i.e. suitable for automated manufacturing.
The application of our microwave drying machine:
This machine fit for drying and sterilizing powered ,granular, sheet-like or gel-like food, and additive, flavoring, medicine, raw material of herbal medicine, nutritional heaLDh products,
agricuLDure & sideline products, non-fried(or oil-saving)instant noodles, noodles, rice powder noodles, soy products, 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 drying beans; and for thawing the frozen fish ,pouLDry;

1.What is microwave?
Microwaves are a form of electromagnetic energy with frequencies between 300 MHz and 300 GHz, generated by magnetrons under the combined force of an electric and a magnetic field perpendicular to each other.
2. What is the advantage of microwave equipment compare to traditional equipment?
Traditional is a surface drying and sterilization method, which is not only slow, but also non-uniform with the surfaces, edges and corners of mushrooms or fungus. The imperfect drying and sterilization will cause product rejections, waste energy and extend process time.
Microwave is a direct method of drying and sterilization. Energy is transferred through the material electro-magnetically, not as a thermal heat flux. Therefore, the effect of drying and sterilization is uniformity and process time is short.
Microwave mushrooms sterilizer and dryer could completely preserve the original color, fragrance, nutrition and other properties of spices.
3. How about safety?
Using scientific structure and patented suppression system, LD company industrial microwave drying machine no threat of electromagnetic radiation to the heaLDh and safety of equipment operators.
