China new tech high effective microwave
packed China new tech high effective microwave packed snack food sterilizing equipment sterilizing equipment
1, What is microwave?
Microwave is a kind of high frequency wave, transform at a speed of 2.4 billion times per second, cause high speed wheel pendulum motion of water molecules, they mutual friction produces a great quantity of heat. So that reached the effect of heating.
2, How does microwave heating/drying/sterilizing for the China new tech high effective microwave packed snack food sterilizing equipment ?
Microwave heating is a progress of relying on object to absorb microwave energy, converts it into heat energy, make its heating whole. while at the same time completely different from other conventional heating methods. Traditional heating mode is according to the principle of heat conduction, convection and radiation heat from the outside to inside, microwave heating technique and traditional heating mode is different, it is through the heated body internal dipole molecule high frequency reciprocating motion, the internal friction make the materail raise up the temperature from inside to outside totally.
Microwave sterilizing principle for the China new tech high effective microwave packed snack food sterilizing equipment products:
1. The heating effect of the microwave energy: in a certain intensity under the action of microwave field, insects and bacteria in food experience by molecular polarization, absorption of microwave energy to heat up, making it the protein denaturation, lose their biological activity.Plays a role of quick heat sterilization microwave thermal effect mainly.
2. Can microwave non-thermal effect: high frequency electric field makes the membrane potential, polar molecule structure change, make the protein and physiological active substances in microbial mutation, and loss of energy or death.In sterilization by conventional physical sterilization no special effect, is also one reason for killing bacteria.
3. The microwave sterilization, keeping fresh is the result of the combination of microwave thermal effect and non-thermal effect.Therefore, microwave sterilization temperature is lower than the conventional method, under normal circumstances, the conventional method of sterilization temperature to 120 ℃ to 130 ℃, time of about 1 hour, and microwave sterilization temperature to 70 ℃ to 105 ℃, only about 90-90 seconds.
3, Application of the mcirowave equipment for the China new tech high effective microwave packed snack food sterilizing equipment drying sterilizing progress:
1) Drying for the dog food.
2) Sterilizing for the dog food.
4, The advantages of the mcirowave equipment for China new tech high effective microwave packed snack food sterilizing equipment progres:
Compare with the traditional drying methods (air, steam, electric heating, etc.), microwave equipment has the following significant "high quality, high efficiency, energy saving, environmental protection" features:
(1) No need heat transfer, the material heating from inside to outside by itself.
(2) Heating very fast, 3-5mins is ok. So that it is suitable for the tea leaves concentration
harvest season.
(3) Clean heating, no need burn the coal /wood etc. So that it can be installed in the city center,
No air pollution.
(4) Multi function, one equipment can do all of these works: drying/sterilizing/puffing.
5, The main parts of the microwave equipment:
Microwave heating equipment includes the following parts:
1. Produce microwave parts, mainly by the microwave generator, microwave tube;
2. The furnace and furnace cavity, with reflective microwave materials, can produce a
microwave resonance;
3. The furnace and microwave agitation or dispersion device;
4. The sealing door parts, to prevent microwave leak;
5. Operation control part includes safety interlocks.
Now mass produced microwave equipment mainly is tunnel type with the conveyor belt.
6, Main parts of the mcirowave source(producer):
The producer of hte mcirowave--magnetron.
Cooling fan for the magnetron and the transformer.
The transformer, capacitance, cilicon.
