Continuous microwave dryer workingprinciple
The radiation of microwave puffing technology is through the electromagnetic energy transmission, the water molecules absorb microwave energy, molecular severe vibration of the gain kinetic energy, gas temperature inside material has rocketed, internal steam formation rate is higher than the rate of migration, make the material in the vapor pressure gradient, when pressure exceeds the capacity of the organization structure, can make material rapidly expanded through the pressure.Microwave puffing technology is the technology development direction, the material in the manufacturing process of short heating time, overcome the Fried expanded product oil problem, microwave puffing equipment is heated evenly, high thermal efficiency, good product quality, equipment cover an area of an area small, easy to control and the advantages of energy-saving, environmental protection, therefore, the microwave puffing prospects are very broad.
Features of Continuous microwave dryer
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.
Application of Continuous microwave dryer
Microwave to dry chemical material, usable range can be used in the iron ore class (limonite, magnetite, hematite, ilmenite, vanadium titanium magnetite, ferrous sulfide nickel, pyrrhotite and pyrite, pyrite, pyrite magnets, etc.), copper (chalcopyrite, bornite, tetrahedrite, cuprous oxide, copper oxide), manganese (soft manganese ore, manganese ore, manganese ore, manganese carbonate, etc.), lead, antimony class (galena, push lead antimony sulfur, etc.) aluminum class (such as diaspore, soft diaspore, sanshui diaspore monohydrate) and other kinds of mineral rapid drying.
