continuous microwave vacuum drying

This equipment Batch Microwave Dryer & Vacuum Dryer is mainly used in drying fish, medicine, sesame, vegetables, fruit, seafood, flowers,such as ginseng, red ginseng, ginseng, angelica, cordyceps sinensis, honeysuckle, conventional, schisandra, astragalus and konjac, yam, maize seed, tobacco seeds, pumpkin, onion, spinach, brake, wild, carrots, celery, cowpea, chili, beans, tomatoes, mushrooms, mushrooms, agaric, garlic, ginger, raisins, kiwi fruit, banana, litchi, longan, apple, hawthorn, persimmon, scallops, dried fish, kelp,vinasse, chrysanthemum, rose dry food processing, etc.Microwave Batch Microwave Dryer & Vacuum Dryer is a sort of electromagnetic wave which frequency is 300GHZ. The water molecule in medium material is polar molecule, under the effect of the repaid change of electromagnetic field, Shandong Leader Machinery Co.,ltd. is polarity orientation will alter with the changes of external electric field with high-speed, causing the movements and friction of molecule, so that the microwave field energy continuous microwave vacuum drying can be converted to heat energy in medium to rise the temperature of materials, accomplishing heating, puffing and a series of physical processes and so Shandong Leader Machinery Co.,ltd. microwave is achieved.

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 energy application
• high-speed control of the energy transport
• short processing times, i.e. suitable for automated manufacturing

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

continuous microwave vacuum drying

This machine Batch Microwave Dryer & Vacuum Dryer is mainly used in all kinds of drying heat sensitive materials, such as polysaccharides, high starch, oil and other materials. In addition, continuous microwave vacuum drying can also be used for the drying, dehydration and concentration of many oxidizable materials.When the equipment continuous microwave vacuum drying is running first by microwave microwave generator, the Fed can input device for microwave heater; material is sent to the transmission system of the heater,Shandong Leader Machinery Co.,ltd. the moisture in the material in the microwave energy under the effect of temperature and evaporation, Batch Microwave Dryer & Vacuum Dryer dry eye to water vapor by eliminating wet pumping system. The bacteria in the material are killed by the biological and thermal effects produced by the microwave electromagnetic field. Because Shandong Leader Machinery Co.,ltd. microwave is directly acting on the material, the drying temperature is low and the speed is fast. The loss of the effective components in the medicine is very small.
