The main indicators of the filtration drying process of barley brewer’s spent grains for industrial drying, as well as the parameters of the necessary drying equipment, were calculated. To compare the effectiveness of the filtration method of drying barley brewer’s spent grain, the drying was calculated for a similar technical task in a rotary dryer. It was found that filtration drying can reduce the required drying time by more than 10 times while increasing the specific energy consumption for removing 1 kg of moisture by 16.8% compared to drying in the rotary dryer.
