Lentinula edodes /mushroom dryer

Main features of microwave drying & sterilization equipment

1.  Rapid drying

Microwave heating does not need the progress of heat conduction, wich make the material itself become a heating unit.

2.  Symmetrical heating

Because of no restrictions on the shape of the material, the materials is heated even, and theres is no adjust outside or unheated inside.

3.  Energy saving and efficient

The microwave drying can save one third energy of the far-infrared drying

4.  Mildewprooding/sterilizing/keeping fresh

Microwave drying with thermal and biological effects can sterilize and resist rot under lower temperature.

5.  Advanced craftwork and easy control

With the use of graphic operation terminal and PlC, you can realize programmable autocontrol of heating progress.

6.  Safety and innocuity.

There is no harmful radioactivity or harmful gas, or waste heat or dust pollution, so neither could microwave heating contaminate food nor pollute the enviroment.

I. General Description

1.Dry temperature:adjustable

2.Type of Feeding:continuous

3.Type of Control:control panel

II. The Features of Design

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 energy generated by

working of machine.

d.The material of machine is made of Stainless Steel.

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.

f. Every magnetron has an overheating protection device.
