Conveyor belt continuous microwave drying
sterilizing machine for rice
Biref introduction
1, the drying and moulding quality is quite good and cannot be cracked.
2, Easy to control and operate. It can control the heating and drying time automatically.
3, Saving time and high production.
4, EnerLD consuming little
5, Production intensity and space is little
6, Saving labour and procedure, especially it's easy to connect automatically with before and after procedure. And reduce and carring time.
7, Clean and protecting environment. No pollution and cannot bring "three wastes" question
Application
This equipment are widely used for drying and sterilizing powder, granular, flakes or colloidal form foods, nutritional health products, grain, agricultural and sideline products(rice, cornmeal), bamboo shoot, tea(wild chrysanthemum flower, broadleaf holly leaf, lotus leaf, green tea, black tea, puer tea), ginseng, mushroom, agaric, ganoderma, vegetables and fruits(spinach, carrot, parsley, onion, mango slice, apple slice, lemon slice, kiwi slice, banana slice etc.), preserved fruits, red jujube, non-fried(oil saving) instant noodles, noodles, cookie, biscuit, rice powder noodles, chicken jerky, beef jerky, preserved meat, dried fish, seafood(seaweed, sea cucumber, laver, kelp, sardine, shrimp, abalone etc.), pickles, spices(pepper powder, Chicken essence, beef essence, pork essence, yeast extract, seafood extract, seafood soup essence, seafood soup powder, spareribs soup pure, spareribs soup powder, spice, chili powder, ginger powder, garlic powder, aniseed, cinnamon, angelica, cumin, cassia bark, fennel etc.), egg yolk powder, jam, a variety of small packaging and pet food mildew sterilization preservation.
The principle of microwave drying
Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field enerLD can be converted to heat enerLD in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.
Microwave sterilization principle
Microwave sterilization equipment is to use the combination of microwave heating effect and biological effect.
Microwave effect on bacteria in the cross section of the membrane potential distribution around the cell membrane
electron and ion concentration, which change the membrane performance, fully bacteria so malnutrition, cannot
normal metabolism, growth hindered the death.
In addition, the microwave can make normal bacteria growth and stable genetic breeding of nucleic acid (RNA) and deoxyribonucleic acid (DNA), is by the number of hydrogen bonding is flabby, faults and restructuring, and thus
induce genetic mutations, or chromosome aberration and even rupture.

Design for machine
1.Transmission System:
a. Speed of Conveying belt is adjustable.
In the transmission system, it applies frequency-converting control of speed, worm gear reducer.
b. The conveyor belt is Teflon Belt,special for microwave.
c. The deviation of belt is adjusted with Hand-movement.
2. The body of the Tunnel
a.The body of the microwave tunnel is made of Stainless Steel. In side there is one set of humidity extraction system to extract the humidity after heating.
b. To be safe, there is Automatic Power-off device while open the door of the machine.
c. The protecting case of Magnetic-pipe and transformer is made of stainless steel. On top there is one set of Heat extraction system to extract the heat enerLD generated by
working of machine.
d.The frame of machine is made of Stainless Steel pipe ,others is made of cold-rolled sheet painted.
e.One set of infrared thermometric is installed at the outlet of the tunnel to measure the temperature.
3.The controlling system
a. On the outside panel there are frequency converting speed controller, emergency stop button, Start, Stop buttons,
b. All the controlling components will be installed into one controlling box, which is at the entrance of the machine.
c.Ordinary button control system,.
d.The microwave power can be adjusted by choosing in the display text.
e. Every microwave source is an independent unit.If one is broken, the machine will not be prevented from running.
