tunnel stevia leaves microwave dryer
Product Description
What's microwave
Microwave are a form of electromagnetic with frequencies between 300MHz and 300GHz,generated by magnetrons under the combined force of an electric and a magnetic field perpendicular to each other.
Working principle
The magnetron produce microwave ,the microwave penetrate the material ,the water molecule (hydrone) fricition,geeting the result of heating and sterilization.
Application range
(1) Food
Such as tea leaves,fruits, vegetables,nut,spice , etc.
(2) Herb
Tablet, pills, powder, capsule, oral liquid, the medicine bottle sterilization ,etc.
(3) Chemical
Glass fiber,chemical raw material, Talc, alumina , foam rubber, etc
(4) Other material
Snacks food puffing, Lady nail drying ,material's sterilization ,kill pest ,etc
Heating feature
(1) fast heating speed , high efficient ,only 2-6mins heating, save cost,
(2) From the surface to the inside uniform and thoroughly heating.
(3) Low temerature heating , keep the color and original nutrition of the material,kill the bacterial and pest at the same time.
(4) Easy to control ,only 1-3 people are enough to operate it .
(5) No environmental pollution.
