Drying rate formula

WebJul 4, 2024 · Energy in drying is in the form of heat, and heat is the simplest form of energy and travels from hotter to cooler medium. Heat leaving away from the system towards surrounding gives the negative heat transfer rates and vice versa. Generally, heat transfer is: Q = mC_ pT . Where, Q=Heat transfer KJ m=Mass of fruit material (kg) WebDrying of grain involves exposing grain to air with low relative humidity which will lead to evaporation of the moisture in the grain and then the moisture’s removal away from the grain. The process includes: moisture removal monitoring drying periods (pre-heating, constant rate, falling rate) increasing drying rate at 18% MC uniform drying
