Airsour air source heat pump dryer, for example, the unit is built-in intelligent segmented constant temperature and humidity process, in each stage of dried purple potatoes, the temperature fluctuations in the drying room is very small, the drying environment and the outside world isolation, is conducive to the accurate application of the baking process. And the whole intelligent operation, through the control panel and mobile devices, you can control the dryer with one key, which greatly saves labor costs.
Meanwhile, Airsour air source heat pump dryer adopts closed drying, which is favorable to the formation and accumulation of aroma-causing substances of purple potatoes. The layout of the hot air system is reasonable, the temperature is evenly distributed, effectively avoiding the phenomenon of incomplete local drying, and the quality of purple potatoes has been significantly improved.
