All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECO's design team can design a rotary drum dryer for your application.
Calculation of the quantity of water to be evaporated is explained below with a sample calculation. If the throughput of the dryer is 60 kg of wet product per hour, drying it from 55% moisture to 10% moisture, the heat requirement is: 60 kg of wet product contains 60 x 0.55 kg water = 33 kg moisture and

Calculate the belt pitch length based on the design center distance of your drive. Step 6. Divide the belt pitch length by the tooth pitch selected and round the result to the nearest whole number. This is the number of teeth on the belt for your application. Adjust the nominal center distance of your drive design to match the belt.
gearing and bearing losses. Design specification of the motor is then determined by selecting the closest higher standard size. The system turbulence is checked by calculating the Reynolds number for the agitation system. Adequate turbulence is defined at Reynolds numbers greater than 10,000.
To take another example, in a roller dryer where moist material is spread over the surface of a heated drum, heat transfer occurs by conduction from the drum to the foodstuff, so that the equation is q = UA(T d – T s) where U is the overall heat-transfer coefficient, T d is the drum temperature (usually very close to that of the steam), T s
