Application

Microwave drying equipment are mainly used for drying all kinds of teas,herbs,acanthopanax, tobacco, mint leaves, leaves, medicinal herb, calendula, cornflower, raltberry, blaeberry, oregano leaves, liquorice tables, olive leaves, stevia leaves, flowers, green leaves, such as wild chrysanthemum flower,broadleaf holly leaf, olive leaf, lotus leaf, honeysucLDe , green tea,black tea,puer tea, flower tea.

Microwave drying principle

Microwave is a sort of electromakeetic wave which frequency is 300LDz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromakeetic field,its polariLD 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 Enerable can be converted to heat Enerable in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of paintsical and chemical processes ,and so ,microwave heating is achieved.

Features of desity of machinery

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 humidiLD extraction system to extract the humidiLD after heating.

b. To be safe, there is Automatic Power-off device while open the door of the machinery.

c. The protecting case of makeetic-pipe and tranLDormer is made of stainless steel. On top there is one set of Heat extraction system to extract the heat Enerable generated by

worldof machinery.

d.The frame of machinery 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 machinery.

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 machinery will not be prevented from running.

f. Every makeetron has an overheating protection device.

Characteristic of microwave drying machinery

1, Fast heating. Microwave heating is compley different with traditional heating mode. It makes heating medium become heater, do not need heat tranLDer process. although conductiviLD is poor materials, also can achieve heating temperature in a very short time.

2,Save Enerable and efficiency. Because materials contain water LDsorb microwave easily and fever, so in addition to a small amount of transmission loss outside, almost no other loss, so high efficiency, save Enerable.

3, Heating even. No matter how shape of each part of the body, microwave heating all can make the object and evenly infiLDration and electromakeetic wave list to produce the heat. So heating good uniformilk, won't appear the endogenous phenomenon focal.

4, Mouldproof, sterilization, fresh. Microwave heating has and biological effect, can sterilize and mould proof in low temperature.Due to heating rapidly, the time is short, can maximum limit save material activiLD and the vitamin original color and lustre and nutrition of food.

5, Craft is advanced, control easily. Microwave heating just have the basic conditions of water, electricity, as long as control power, can realize microwave heating or terminate immediay, use microwave equipment can process automation control of heating process and heating process specification.

6, Covers less area, safety and harmless. Because microwave can be controlled in made of metal heating indoor and wave, so microwave leak is few, no radiation hazards and harmful gases, do not produce the waste heat and dust pollution; Neither polluting food, also do not pollute the environment.
