Reduce water content of beans with rotary dryer

Abstract

Drying (drying) of solids means the separation of small amounts of water or other liquids from solids. One of the rotary kiln dryer (rotary dryer) which consists of a sleeve-shaped rotating cylinder, horizontally, or tilted slightly downward toward the exit, and equipped with DCS (Distributed Control System) which aims to control the manufacturing process continuously or batch-oriented. Materials used in this lab is nuts - the grain, corn and soybeans. In this lab for each - each material performed three variables. Each variable with the same weight of 1000 gr. Drying performed at 50°C, 55°C, 60°C. From lab work in getting the rate of drying is increasingly rising. For the grain at 50°C of 34,12 lb/ft2h, at 55°C of 48,82 lb/ft2h and 60°C of 66,77 lb/ft2h. As for corn at 50°C of 2,131 lb/ft2h, at 55°C of 4,66 lb/ft2h and 60°C of 9,789 lb/ft2h. And for soybeans at 50°C of 3,555 lb/ft2h, 55°C of 4,886 lb/ft2h and 60°C of 9,114 lb/ft2h. Similarly, with water levels rising yawn on the material. For the grain at 50°C at 14%, temperature 55°C by 15%, and 60°C of 15,7%. As for corn at 50°C by 2,5%, temperature 55°C by 5%, and 60°C by 7%. And for soybeans at 50°C at 2%, temperature 55°C by 2,5%, and 60°C by 3,5%. The higher the temperature and the more weight then the weight of the dried material is yawn H2O and the drying rate will further go up. The rate of drying is directly proportional to the temperature and proportional to the weight of the yawn H2O.
