10680*820*1750mm betel nut microwave belt type dryer
This machine is a kind of continuous tunnel drying equipment, it is very convinent to used in industrial batch production.
Definition:
Conventional heating such as flame, hot air, steam drying is using the principle of heat conduction, the heat
from the material external incoming internal, gradually increase the center temperature of the object, called
the external heating.The center part to reach the needed temperature requires a certain amount of time,
poor heat conductivity objects requires longer time. The time of these traditional methods of drying is longer,
larger power consumption, heating is not uniform, flip up and down, large labor intensity, and microwave drying characteristics, microwave energy can penetrate the material, inside and outside can be heated at the same
time, the frequency is 2450MHZ, with every second 2400000000 5 ten million second oscillation, water
molecules are the same is a million times oscillation, molecular mutual friction, then the heat produced. So
self heating

Application:
Our product-microwave equipment used in food, spices, food additives, nuts; sponge, chemical material, paper, wood material,herbs, tea etc
Microwave drying characteristics: drying time is short, strong the smell of the product; drying temperature is
low, uniform, bright color of the product; selective heating. Because the water molecules in the microwave
absorbing the best part of high water content, absorb more microwave power than the water content of the
lower part.
This is the selective heating, the use of this feature can be uniformly heated and uniform drying; dehydration
direction of water vapor from inside to outside. Therefore, microwave drying has puffed role, the subsequent
crushing of great help; energy efficient.
Microwave sterilization features: time, speed: conventional thermal sterilization is through conduction,
convection, or radiation will spread to the internal heat from the food surface. To achieve the sterilization
temperature, often takes a long time. Microwave sterilization is the direct interaction between microwave
energy and food as well as bacteria and other microbes, thermal effects and non-thermal effects together to achieve rapid heating sterilization, processing time is greatly reduced, the
bactericidal effect of the various materials within 3-5 minutes.
Low-temperature sterilization to keep the nutrients and flavor.
Operating principal:
This microwave source adopts continuous microwave magnetron as its microwave oscillation source. The
continuous magnetron is a kind of cross-field microwave radio tube, the direct current field and
the stationary magnetic field are vertical. The anode of the magnetron is a complex system of resonance.
The anode block consists of many little resonant cavity. Between them there is inductance coupling, so the
anode block is the crossover network of microwave. The electron eradiated from the cathode of the magnetron
will firstly be affected by the direct current field and curl like an angle. While the electrons are moving from
the cathode to the anode, the contrail of their movement is like a swing vibration. Under the condition
of synchronism between high frequency field and electron cloud, the electron contrail will rise toward the
anode direction and form electron spoke. Among the spoke, while the electrons are carrying through
synchronistically, they will change the potential energy into high frequency energy and increase the high
frequency breadth. After themagnetron is started, the direct current which is instored in the resonance
cavity will be changed into super-high frequency energy, finally, microwave source of enough power will exported through wave-guide.
structure and characteristics:
The multifunction microwave sterilizing and drying equipment is the upgrading and updating products
of the common continuous microwave one. it may adopt cutting-edge technical means according to
customers requirement, collocated with PLC human-machine interface auto-control system, it is
convenient to set arts and crafts parameters like temperature, power, speed, time and failure warning.
Inside the human-machine interface, the equipment running mimic diagram, the instructions
of equipment operation, the failure maintenancem, knowledge-reading, the enterprises brief introduction
is available for the customers reference.
We can manufacture the Non-standard equipment according to the requirement of customers
Microwave heating and drying, sterilization characteristics:
1.Heated rapidly, uniformly
Without heat conduction process, in an instant it can penetrate into the material is heated, the penetration depth of a few centimeters or even tens of centimeters, seconds to minutes microwave into heat. Microwave selective heating, and will allow more uniform heating.
2.Efficiently
Material containing moisture can easily absorb microwave heat, therefore, almost no other losses in addition to a small amount of transmission loss. Microwave heating compared with the far-infrared heating, saving energy 1/3 to 2/3.
3Anti-virus sterilization preservation
Microwave heating with thermal effects and biological effects, therefore, at lower temperatures, anti-virus bacteria and bacteria; can save the material activity and food vitamins, color and nutrients.
4.Advanced technology, continuous production
As long as the microwave power to heat or to terminate. Transmission system to ensure continuous production, saving capabilities.
5. safe
The microwave energy is to control the metal is heated indoor wave tube work, microwave leakage is effectively suppressed. Radiation hazards and harmful emissions, does not produce waste heat, neither contaminate food, do not pollute the environment
