Cost performance of Microwave sterilization drying equipment and other dry sterilization equipment
1. The microwave sterilization drying equipment heating speed
Conventional heating, such as flame, hot air, heating, steam, etc., is using the principle of heat transfer heat from the heated objects outside into the inside, gradually make material center temperature, called external heating.
To attain the required temperature center, need a certain amount of time, the time needed for the poor thermal conductivity of material is longer.
Microwave sterilization drying is the heating material as heating element, the province is called internal heating mode, do not need to heat transfer process, inside and outside the heating at the same time, so in more time to achieve the effect of heating.
2. The microwave drying equipment uniform heating
Conventional heating, to improve the heating speed, requires higher heating temperature, easy to produce coke endogenous phenomenon.
Microwave heating, the object can usually even penetration of electromagnetic wave, the parts to generate heat, so the uniformity is greatly improved.
3. The microwave energy efficient equipment
In microwave heating, microwave energy can only be heated objects attract and heating, heating chamber wall and heated indoor air and the corresponding container will not heat, so heat effect is extremely high, produce environment has improved significantly.
4. Microwave equipment is easy to control
Microwave heating the thermal inertia of small, if with microcomputer control, are particularly suitable for automatic control of heating process and heating process.
Microwave powder industry application
The product description
Microwave chemical powder drying machine is according to the special requirements of powder industry, carries on the unique design of high-efficiency powder microwave drying equipment.

2, materials microwave drying equipment (battery powder materials)
Ternary material is nickel cobalt manganese acid lithium Li (NiCoMn) O2, ternary composite cathode material precursor products, is the cobalt nickel salt, salt, manganese salt as raw materials, in the proportion of nickel cobalt manganese can according to the actual need to adjust.
Our company developed equipment used in batteries ternary material drying, dry, dry efficiency is superior to conventional methods, no dust pollution, video monitoring equipment production process, the drying temperature automatic adjustment control, is suitable for industrialized production requirements.
This equipment is also suitable for 3 yuan, cobalt acid lithium battery materials, lithium iron phosphate, nickel hydroxide, graphite, lithium carbonate, rubber accelerator, calcium carbonate, zirconium silicate, manganese ore, mannitol, silicon carbide and other materials drying, has started large-scale use.
3, rubber accelerator microwave drying equipment
This is my company professional for domestic rubber additives manufacturers custom a energy-efficient drying equipment.
By microwave drying equipment, high efficiency, easy operation, all the production of stainless steel plate can be used in dry rubber additives, corrosion resistance is strong, can be used in the large majority of dry powder chemical products, can also be used for other chemical, pharmaceutical, building materials industries such as dry powder, granule materials.
Have with the series of products are: dry starch, glucose, fish meal, sugar, sugar, wine trough, feed, gluten, plastic resin, coal powder, dye, etc.
Microwave drying can also be used as rubber fertilizer additives for rubber dryers, methaqualone dedicated dryer, calcium phosphate special dryers.
Microwave plasma applications
The low temperature plasma (temperature is 2000 ~ 50000 k) has been widely used, the industry has become an important means of technology, such as using plasma arc cutting, welding, spraying;
Manufacture all kinds of new light source and display;
Thermoelectric conversion directly MHD power generation, etc.
In the chemical engineering department, plasma chemistry has become a new field of very active.
In the microelectronics industry, plasma etching and deposition was widely applied.
Above situation shows that low temperature plasma has gradually penetrated into many areas, shows a broad prospect.
the excitation with microwave plasma has the following advantages:
1. A higher degree of ionization and decomposition
2. The electron temperature and ion temperature on the ratio of the gas temperature is very high, in the carrier gas to keep the right temperature.
This feature, in the case of vapor deposition, can make the temperature of the substrate will not too high.
3. Can maintain plasma under high pressure.
4. No internal electrode in plasma container, no any matter beyond the working gas, are clean, no pollution.
Plasma generator can keep long life.
5. Plasma can adopt the method of magnetic confinement, the constraint within the space in, microwave and magnetic circuit can be compatible.
6. High safety factor.
High voltage source and plasma generator isolation from each other, this is a dc plasma cannot achieve.
Microwave leakage is small, easy to achieve the radiation safety standards.
It is difficult to achieve high frequency induction plasma.
7. The microwave generator is stable, easy to control.
8. Microwave plasma, in many cases is a relatively quiet plasma, unlike dc discharge with high noise level.
Microwave excitation plasma a variety of forms:
1. The microwave transmission line and the cavity.
2. The edge field slow wave structure.
3. The near-field microwave antenna.
4. Stimulate plasma column and waveguide coaxial base surface wave base surface wave plasma column.
5. Using electron cyclotron resonance plasma.
