The tolerance temperature of red beans is high, so it is also a materials that is easier to dry. According to the calculation, if you use a set of 3P drying and dehumidification integrated host to configure a 10 cm polyurethane thermal insulation drying room with a length of 3.5 meters, a width of 2.2 meters, and a height of 2.2 meters, you can load 300-350 kg of red beans for drying in one time. During the drying process, the initial temperature can be set to 60 °C, and the maximum temperature can be set to 70 °C. Drying a batch of red beans takes 15-18 hours to complete. Continuous heating and continuous dehumidification should be carried out in parallel.
