Small Microwave Low-temperature Vacuum Drying Machine/Batch Vacuum Dryer

 Working Principle and Main Feature:

1. The machine adopts vacuum pump for sucking the air and moisture from the inner machine, make the raw materials are under vacuum situation for heating and fast drying.
2. When the temperature is fixed, and increases the vacuum rate of the inner machine, it will help to make the drying more faster.
3. When the temperature is fixed, and increase the vacuum rate, it will also make the drying faster.
4. If increase both vacuum rate and temperature degree, then the drying speed will be faster.
5. The machine can be equipped with condenser for Solvent recovery which contains in raw materials.

Product Technical Features Of Microwave Dryer Machine:

1. Under the condition of vacuum, low evaporation temperature of the water, realized the low temperature drying, intact for processing materials of the original color, flavor and nutrition, avoid the material in the active ingredient of the oxidation, products after good water; 
2. Microwaves penetrate to the material internal, rotary vacuum cavity system relative levels of rotary motion drive material, the material is heated more evenly, fast drying, its running cost is much lower than the vacuum freeze-drying, saving energy and reducing consumption, health, environmental protection; 
3. The perfect mechanical and electrical integration design, the real-time monitoring of multiple sensors, PLC program control, infrared temperature measurement, according to the system safe and reliable; 
4. Can be set overtemperature alarm, implementation of closed-loop control, strictly control the material temperature low water cut stage.
5. High voltage transformer adopted in the secondary cooling system to ensure that the equipment can work 24 hours continuously.

Application:

Microwave industrial tunnel baking&puffing equipment are widely used in the peanuts,sesame seeds,wheat,melon seeds,sunflower seeds,peanuts,corn,soybeans,walnuts,almonds,chestnuts, pistachios,cashews,filbert and dried fruit etc;and for puffing of leisure food,pachyrhizus chips,potato chips,dried shrimps,fish maw and so on.Compared with the traditional production methods,microwave baking foods are crispy and delicious,puffed full of particles,natural color, beautiful appearance,and has insecticidal sterilization effect.
