Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect heated type. Often, indirect heated dryers are used when product contamination is a concern.
1)Tunnel-type Microwave Dryer is made of high-quality 304# stainless steel.Fully meet with medicine machinery requirements.
2)Low-temperature drying and sterilization,which can keep original flavor and good color sense.
3)Penetration:Tunnel-type Microwave Drying Machine adopts radiation way to transfer energy and it heat wholly without any medium.
4)Heating evenly:microwave heating is in and outside of the material at the same time,the temperature difference is very small in and outside of the material.So it is more evenly when drying materials,and the heating efficiency is greatly increased.
5)Quickly and saving energy.
