Pht 321: factors affecting dehydration

4. size, shape and arrangement of stacking of the raw material 5. temperature, relative humidity and velocity of air used for drying 6. rate of heat transfer on the surface of the food 7. pre-treatment of the raw material prior to drying (peeling, blanching, sulphuring etc.)

sep 23, 2020 sep 23, 2020 the higher the temperature of the hot air, the more heat energy it contains, and the lower the relative humidity of the hot air, the stronger the ability to absorb and carry water, which is very conducive to drying, and the drying heat efficiency is also high. in many drying equipment, when other conditions remain unchanged, the dehydration capacity of the dryer is

1, the size of the towel dryer heater power. the greater the heat power of the heater, the more heat energy is generated per unit time, the easier it is to dry the clothes. the most common heating methods for the dryer are electric heating, steam heating, gas heating, and the heat power is in unit time.

factors affecting the drying rate are as follows: • air temperature surrounding the pellets—at higher temperatures, air can hold more water, and the diffusion rate in the pellets is faster. • air dew point—lower air dew point lowers the air moisture content and provides a larger driving force for water migration from the pellet to the air.

drying efficiency. the efficiency of the drying operation is an important factor in the assessment and selection of the optimum dryer for a particular task. there are three groups of factors affecting drying efficiency: * those related to the environment, in particular, ambient air conditions; *

factors affecting dehydration. important factors affecting the rate of drying are: 1. initial moisture content of the raw material. 2. composition of raw material. 3. initial load of the food kept in drier. 4.
