Various factors affect the cooling and drying process of material particles. The energy in the air and particles and the amount of water in the particles and air directly affect the cooling and drying process. The methods of heat and mass transfer are also used: conditions, convection, absorption, and adsorption Etc. significantly affect the cooling and drying process. The type of cooler used in the drying equipment and the heat and mass transfer method of the cooler design used will affect the cooling and drying process of the feed particles.
In addition, the cooling rate should not be too fast: a dry shell will form on the surface of the particles, which will hinder the migration of water from the particles and keep the particle core soft and moist. Once the particles with this soft and moist core reach equilibrium, the particles will become brittle and produce excessive fines.
The factors affecting the cooling performance of the tube bundle dryer particles can be summarized as: cooler type, air flow rate, air temperature, air humidity, particle flow rate, particle temperature, particle moisture content and particle size.https://www.stordworkshop.com/
