30kw rice powder/albumen powder/spices powder drying and

sterilizing equipment

Function:

Herbs, spices, spice powder, food powder, grain powder, tea leaves, fruits, nuts, beans, grain, wood, board, paper drying / sterilizing.

1, 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.

2, Microwave drying principle

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 drying is achieved.

3, Microwave dryer and sterilizer mainly used on the products:

1. Spices :chilli powder, garlic slices, ground pepper, ginger powder, curry powder,

cinnamon, vanilla, cardaamun, myristica fragrans ,radix angelicae,

Rhizoma Kaempferiae, medlar, cumin, root of hairy asiabell, fennel.

2, food: egg powder, grain powder, beans, nut, small packed snack, beef jerky, dryed sea food, marmalade, etc.

6. Microwave drying 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, Mould proof, 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 color 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.
