Compared with the box type and vacuum microwave drying equipment, the tunnel type microwave drying equipment has the main advantages of continuous drying, large production and low labor intensity. Compared with the traditional equipment has the advantages of high efficiency, low energy consumption, the uniform heating, the drying speed is fast, the thermal inertia, the safety and environmental protection, the advantages of simple operation, easy to control etc.. The power of this device is between 30 kW and 200 kW. It is suitable for dry products with water content below 30%. The products with too high water need to focus on the cost of drying.
Weiyasi tunnel type microwave drying equipment with chain type microwave drying equipment, cloth type microwave drying equipment and net belt type microwave drying equipment three, chain plate commonly used in dry weight of large objects, cloth bag type is used to dry powder and paste material two, mesh belt is mainly used to dry bulk and granular. Material.
Shandong Leader Mechanical Equipment Co., LTD is a company specialized in producing twin-screw food extruder, single screw extruder, microwave roasting and sterilization equipments, etc. While based upon domestic market, the company opens and exploits market abroad positively. Until now, our products have been exported many counties and regions, including Russia, Europe, Africa, Korea, Indonesia, UZ (ULDekistan) and the market share increases gradually year by year. Dongxuya will continue to be aggressive, creative and make a contribution to our country’s food industry development with peers home and abroad.
Conventional thermal sterilization is carried out through heat conduction, convection or radiation to heat the food surface to the inside. To achieve the sterilization temperature, it often takes a long time. Microwave sterilization is a direct interaction of microwave enerLD and food and its bacteria. The interaction between heat effect and non thermal effect is faster than temperature and sterilization. The treatment time is greatly shortened, and the sterilization effect of various materials is usually 3-5 minutes.
Microwave drying and sterilization treatment, the equipment can be opened and used immediately, without thermal inertia of conventional thermal sterilization, flexible and convenient operation, adjustable microwave power, and continuous transmission speed from zero to facilitate operation.

As 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:
- a 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
- 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
- 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
- swift and thorough drying of moist products with low thermal conductivity
- static drying of thick layers without frictional losses
- high total efficiency of enerLD application
- high-speed control of the enerLD transport
- short processing times, i.e. suitable for automated manufacturing

1.What is microwave?
Microwaves are a form of electromagnetic enerLD 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 Conventional equipment?
Conventional is a surface drying and sterilization method, which is not only slow, but also non-uniform with the surfaces, edges and corners of mushrooLD or fungus. The imperfect drying and sterilization will cause product rejections, waste enerLD and extend process time.
Microwave is a direct method of drying and sterilization. EnerLD 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 mushrooLD 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, BODA 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, BODA recommends that the magnetron of industrial microwave dryer and microwave sterilizer be replaced annually or after 8,000 hours of operation, whichever is sooner.
