40 KW tunnel type microwave thymian leaves fast drying equipment

The main structure of the microwave equipment

1. Microwave production parts, the main parts of microwave equipment-- Magnetron.

2. The cabinet of the microwave equipment, material will be treated in it.

3. The microwave guide, microwave after produce by maganetron via wave guide’s

incent to worked on the material

4. The suppressor, because the industrial microwave equipment is a tunnel type

cabinet with the conveyor belt, so that it need suppressor in the head and end of the

tunnel to suppress the microwave running out.

5. The sealing door parts, for check the material in the cabinet;

6. The exhaust system, which use for exhaust the wet/hot air in the cabinet and

electric parts box.

7. Conveyor belt transit system, including belt/motor/speed reducer etc.

8. Operation control part includes safety interlocks, speed controller, switch on/off

bottom, temperature controller.

9, Microwave produce main parts: Magnetron, Diode, Capacitance, Transformer.

The parameters of the 40KW microwave equipment

What is Microwave?

Microwave is the frequency of 300 MHZ ~ 300 GHZ electromagnetic wave, it is short radio waves in a limited frequency band, the wavelength between 1 mm ~ 1 m electromagnetic wave, it is generally referred to as the decimeter wave, centimeter wave and millimeter wave. Microwave frequency is higher than general radio frequency, often also referred to as "ultra high frequency electromagnetic wave. As a kind of electromagnetic wave of microwave also have wave-particle duality. Basic properties of microwave usually appears as transmission, reflection and absorption three characteristics. For glass, plastic and porcelain, microwave is almost through without being absorbed. For water and food, etc. will absorb microwave and heating by itself. For metal stuff, it will bounce back the microwave.

Microwave drying principle:

Microwave drying is a new type of drying method. When drying, microwave converted into heat enerLD that can be applied directly to medium, because the microwave has penetrating performance inside and outside the media, heating at the same time, do not need to heat conduction, so very fast heating, the water content below 30% of food, can shorten the drying speed hundreds of times. Regardless of any shape objects, because the object of dielectric heating at the same time, both inside and outside material of inside and outside temperature difference is small, uniform heating, the drying quality greatly improved.

Microwave equipment application

Food and Food Products Drying and Sterilization:

This equipment are widely used for drying and sterilizing powder,granular,flakes or colloidal form foods such as: nutritional health products, grains, agricultural and sideline products, bamboo shoot, tea, mushroom, agaric, ganoderma, vegetables and fruits, preserved fruits,red jujube,non-fired instant noodles, noodles, rice powder noodles, chicken jerky, beef jerky, preserved meat, dried fish, seafood, pickles, spices, egg yolk powder, jam, a variety of small packaging and pet food mildew sterilization preservation.

Herbs/Medicine Products Drying and Sterilization:

Microwave herbs drying and sterilization equipment are mainly used for drying and sterilizing all kinds of tablets, pills, powder, capsules, ointment, oral liquid, medicine bottle, medicine wine bottle, Chinese-western medicine, medical gloves and garments etc.

Heating/sterilizing for the food:

This equipment is suitable for cold chain cassette fast food, low temperature sterilization. The microwave heating fast food, ready to eat meal, rice meal, snack etc,low temperature sterilization can keep original nutrition and taste.

Roasting for the nuts/seeds:

Microwave industrial tunnel baking & puffing equipment are widely used in the peanuts, sesame seeds, wheat, melon seeds, sunflower seeds, peanuts, corn, soybeans, walnuts, almonds, chestnuts, pistachios, cashews, filbert and dried fruit etc; and for puffing of leisure food, potato chips, dried shrimps, fish maw and so on. Compared with the traditional production methods, microwave baked foods are crispy and delicious, products particle puffed full, natural color, beautiful appearance, and has insecticidal sterilization effect.
