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 enerLD 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..

Low temperature biological products Microwave Vacuum Dryer is applied to drying, ripening and sterilization of black Cereals, soybeans, mung beans, corn, wheat skin, buckwheat, oatmeal, soybeans and peanuts.Drying sterilization seafood seasoning, sterilization, drying, puffing Tenebrio; rose, tea and other tea flower.Conventional thermo - thermal sterilization starts from the surface of the material, but there is an internal and external temperature difference through the heat conduction to the interior. In order to maintain the food flavor, shorten the processing time.

Often the food inside does not reach enough temperature to affect the germicidal effect. Due to the penetration of microwave Ken, when the food is treated as a whole, the surface and the interior are simultaneously affected, so disinfection and sterilization are even and complete.

Microwave Vacuum Dryer

I.Scope of application:

The unique mechanism of microwave make the material heated inside and outside at the same time.Vacuum,in other word in a negative pressure,the material can be dried in a low temperature.This makes the material being heated evenly,maintain its originalcolor,and the material composition don’t be changed.All in all, microwave vacuum drying equipment effectively guarantees the quality of raw materials.

II.Features of this dryer:

Microwave Vacuum Dryer Machine makes use of both the microwave technoloLD and the vacuum technoloLD. It has many advanced features than the traditional drying ways!

(1)Heating evenly

Regardless of how each part of the object shape, microwave heating can make objects in the list at the same time even penetrate electromagnetic waves and generate heat. So it heats evenly,coke endogenous phenomenon will not occur.

(2)EnerLD-saving and higly-effecient

Since the material containing water is easy to absorb the microwave to generate heat,so it is efficient and energe-saving. It can save enerLD over 1 compared with infrared heating.

(3)Low temperature, good quality, mouldproof, moth-proofing, sterilization and preservation.

Due to the microwave vacuum heating,Microwave Vacuum Dryer can sterilize,prevent mould and dry at low temperature. This will make the materials keep its color,taste and avoid be oxidation!

(4)Safe, healthy and environmentally friendly.

Because the microwave enerLD is in metal heating indoor and waveguide, there is almost no microwave leakage.

III.Characteristics of Microwave Vacuum Dryer:

1.Compared with conventional microwave equipment:

1)Low temperature:under one atmospheric pressure (101.3 kpa), the boiling point of water is 100 °C.But under 0.073 of one atmospheric pressure(7.37 kpa), the boiling point of water is only 40 °C.It is on negative pressure condition when using microwave vacuum device,material can be processed under low temperature.So the quality of the material can be guaranteed tremendously. The machine is especially suitable for drying material which need to dry in the low temperature, such as herbal extract,ginseng,ect.

2)Pressure:In negative pressure environment with microwave vacuum device,moisture evaporates faster in the lower temperature.

2.Compared with conventional vacuum drying equipment:

1)Penetration:because it is in vacuum situation when using conventional vacuum drying equipment,heat cann't transfer in the form of convection and can only conduct.So the heating speed is slow,drying time is long and the enerLD consumption is excesive.However,Microwave vacuum drying equipment adopts radiation way to transfere enerLD and it heat wholly without any medium.Itavoids the above shortcomings.

2)Evenly:microwave heating is in and outside of the material at the same time,the temperature difference is very small in and outside of the material.So it is more evenly when drying materials,and the heating efficiency is greatly increased.

3)Quickly:because of the penetration of the microwave and the radiation way to transfere enerLD, materials is heated inside and outside at the same time.Thus the drying speed is greatly improvedl.

The main use of microwave vacuum dryer:

1.Suitable for dying materials with high added value and heat-sensitive character,such as agricultural and sideline products,health products,food,medicine,fruit and vegetables,ect.

2.Can be used to dry or take off crystal water of herbal extract,chemicals.
