High efficiently cocoa bean tunnel dryer/ microwave drying machine
The working principle of High efficiently cocoa bean tunnel dryer/ microwave drying machine:
The working principle is that microwave is issued by the microwave generator, formed a strong magnetic field in the microwave drying cavity. The water molecules in the material produced high speed reciprocating motion by the polarity change in the magnetic field, friction heat, and then for the purpose of drying and sterilization.
1) Machine material: food-grade SUS304 stainless steel
2) Energy-saving more than 30%
3) High production efficiency
4) Improve product quality: nice color and good taste
5) Safety and easy clear.
6) Improve working conditions: PLC touch screen control, automatically operation
The features of High efficiently cocoa bean tunnel dryer/ microwave drying machine:
1, Control modes:
PLC control, man-machine interface operation, high automation degree.
The console is arranged in the feeding end equipment, using PLC and image monitoring technology (monitoring points: intermediate operating cavity), realized the visualization of the drying process. With preventing microwave leakage detection device can realize the automatic alarm function.
2, Power control:
Packet control microwave system, achieved a high degree of automation and humanization idea industrial microwave equipment according to set program automatic adjustment output microwave intensity;
3, Temperature control:
Using the real-time temperature measuring precision in the drying process, according to the set temperature requirements, automatic regulated microwave field strength. Configure automatic smoke sensing device, overheat burning , automatic shutdown. realized the process requirements and equipment self protection function;
4, Variable frequency speed regulation:
The transmission speed variable frequency adjustable, adjusted the best effect by combining the material properties and microwave intensity. Implanted into the automation program, realized the automatic operation. Not only can improve the product quality, but also can save the manpower cost.
5, Working state display and monitoring (electrical elements, motion device, current, voltage etc) :
In the event of fault point, automatic protection operation. For fault recovery, started by the operating personnel.
6, Setting the emergency switch, circuit arranged in neat rows, obvious marks, line machine.

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, 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, resulting in a high drying velocity.
3, the heating of water and most organic solvents occurs selectively - due to the greater dielectric losses of water as compared to the product to be dried.
4, swift 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:
1. The flavorings spice,
2. Subsidiary agricultural products, deep processing products of fruit, vegetable
3. Various dried meat, like beef, pork, chicken, duck, fish etc.
4. The grain, the deep manufactured products
5. Sterilization of beverage and the wine, the meat, the marine product, the roasted seeds and nuts, and etc.
6. Chemical material, medicine tablet
7. Powder for various material.

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, GREAT company industrial microwave drying machine no threat of electromagnetic radiation to the health and safety of equipment operators.
4.What about maintenance?
In addition to downtime for cleaning and inspection, conventional sterilizers and heat exchangers need periodic servicing with an expensive inventory of parts and a highly trained labor force. For microwave dryer and sterilizer, the only part that requires maintenance is the magnetron. In the event of a malfunction or misuse through incorrect operation, this can easily be replaced in less than thirty minutes. Generally, GREAT recommends that the magnetron of industrial microwave dryer and microwave sterilizer be replaced annually or after 8,000 hours of operation,
