China top quality black tea microwave tunnel drying /sterilizing machine
The specification of China top quality black tea microwave tunnel drying /sterilizing machine :
1)Machine material: food-grade SUS304 stainless steel 2)Energy-saving more than 30% 3)High production efficiency 4)Improve product quality: nice color and good taste 5)Safety and easy clear. 6)Improve working conditions: PLC touch screen control, automatically operation
The features of China top quality black tea microwave tunnel drying /sterilizing machine :
1, theworking principle:
microwave is issued by the microwave generator, formed a strong magnetic field in the microwave sterilization cavity. The water molecules in the material produced high speed reciprocating motion by the polarity change in the magnetic field, friction heat, and then for the purpose of sterilization.
2, Control modes:
PLC control, man-machine interface operation, high automation degree.
The console is arranged in the feeding end equipment, using PLC and image monitoring technology(monitoring points: intermediate operating cavity), realized the visualization of the drying process. Withpreventing microwave leakage detection device can realize the automatic alarm function.
3, Power control:
Packet control microwave system, achieved a high degree of automation and humanization ideaindustrial microwave equipment according to set program automatic adjustment output microwaveintensity;
4, Temperature control:
Using the real-time temperature measuring precision in the drying process, according to the settemperature requirements, automatic regulated microwave field strength. Configure automatic smokesensing device, overheat burning , automatic shutdown. realized the process requirements andequipment self protection function;
5, Variable frequency speed regulation: The transmission speed variable frequency adjustable, adjusted the best effect by combining thematerial properties and microwave intensity. Implanted into the automation program, realized theautomatic operation. Not only can improve the product quality, but also can save the manpower cost.

we made a such successful case for Baby powder:
Baby Powder Sterilization:
1, It is suitable for microwave sterilization with high production efficiency.
2, Its temprature is over 100 degree.
3, Its original total numbers of colony(bacteria) is 3800 cfu/gm. and after microwave sterilization, the total numbers of colony is 50 cfu/gm.
You can send your sample to us if you feel maybe it's impossible for your material, we can test it for you about drying and sterilization for free.
Advantages
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:
1, 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.
2, 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.
3, 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.
4, swift and thorough drying of moist products with low thermal conductivity static drying of thick layers without frictional losses.
5, high total efficiency of energy application and high-speed control of the energy transport.
6,short processing times, i.e. suitable for automated manufacturing.
The application of our microwave drying machine:
1. The flavorings spice,
2. Subsidiary agricultural products, deep processing products of fruit, vegetable
3. Various dried meat, like beef, pork, chicken, duck, fish etc.
4. The grain, the deep manufactured products
5. Sterilization of beverage and the wine, the meat, the marine product, the roasted seeds and nuts, and etc.
