5)Safety and easy clear.
6)Improve working conditions: PLC touch screen control, automatically operation
The function of high-efficient tunnel mircowave drying equipment for broad bean :
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.
The features of high-efficient tunnel mircowave drying equipment for broad bean :
1, the working principle:
microwave is issued by the microwave generator, formed a strong magnetic field in the microwave sterilization 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 sterilization.
2, 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. Withpreventing microwave leakage detection device can realize the automatic alarm function.
3, Power control:
Packet control microwave system, achieved a high degree of automation and humanization ideaindustrial microwave equipment according to set program automatic adjustment output microwaveintensity;
4, Temperature control:
Using the real-time temperature measuring precision in the drying process, according to the settemperature requirements, automatic regulated microwave field strength. Configure automatic smokesensing device, overheat burning , automatic shutdown. realized the process requirements andequipment self protection function;
5, Variable frequency speed regulation:
The transmission speed variable frequency adjustable, adjusted the best effect by combining thematerial properties and microwave intensity. Implanted into the automation program, realized theautomatic operation. Not only can improve the product quality, but also can save the manpower cost.
6, Mechanical system:
||Microwave leakage( mW/cm2 )
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:
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.
LD Machinery provides a full range of services and technical support for industrial microwave systems. The services include custom installations, preventive equipment maintenance, equipment upgrades and modifications and microwave system repair.

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.
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, LD recommends that the magnetron of industrial microwave dryer and microwave sterilizer be replaced annually or after 8,000 hours of operation,
