High Tech Screen Printing Conveyor Dryer/Tunnel Dryer and Screen Printing Machine

Description

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.

Features

Different heating and circulation method is available for choice.
Length , width and layer quantity of belt is designed based on production requirement.
The machine pre-dehydration process could remove massive moisture on leaf surface, thus reduced the drying strength, and reduced the energy consumption.
Special hot air drying system, increase material penetrability and drying rate.
The adjustment of belt speed and the different section temperature control, it guaranteed the drying time and material quality and color.
Strong magnetism iron removal device is available for choice, it could remove metal impurities effectively.
