A.  Summary

HG Model Dryer is a new model, which is widely applied to the drying/flaking process of sticky and pasted materials. With reliable performance, it enjoys great popularity in foodstuff, pharmaceutical, chemical and other fields.

B.  Work Principle

The work principle of HG Model Dryer is to let the liquid or slurry materials form thin film on the surface of the roller heated either by steam or other heating media. It features a bigger heating surface area, higher heat efficiency and even heating. Moreover, the heating time is rather short which lasts about 10~15 seconds, so the machine is particularly suitable for the applications of drying of heat-sensitive materials. The products finish being dried once the roller turns a circle, meanwhile the scrapers are performed to wipe down the products. The products coming out from the surface of the roller will be in contact with the raw materials again to form/and stack up another thin film for being dried repeatedly. 

C.  Configuration: 

HG Model Roller Scraper Dryer consists of the roller, the support, the feeding device (the upper feeding or the bottom feeding by soaking), driving unit, hopper, induced draft fan and scraper device. 

D.  Features: 

1) Using steam or thermal oil as the heating medium, it features big heating area and high heat efficiency and being evenly heated.

2) The drying ratio is high and temperature gradient is big, which enables the surface of the material films to keep higher evaporation strength.

3) It also features shorter drying time, about 10~15 second, which is quite suitable for heat-sensitive materials. 

4) It also features easy operation and easy maintenance.

The Model No. is HG1500-2500(the pictures only show the main machine), the main construction material is SS304.  It is a Single Roller Type, with steam jacket for heating.
