乾燥室中的低溫乾燥指溫度不超過45度。低溫乾燥類似於室溫乾燥。與高溫乾燥相比，低溫乾燥需要更長的乾燥時間。低溫乾燥可保持材料的原有品質，價格與成本高於高溫乾燥，且低溫乾燥能有效防止因天氣潮濕導致材料發霉。乾燥室在乾燥過程中使用低溫乾燥，以保留材料的原始香氣與活性，並確保材料能完全乾燥，乾燥後的材料口感良好。
當乾燥室使用高溫乾燥時，乾燥溫度通常大於40度。乾燥時間短，成本低，且不受天氣影響。乾燥材料的品質通常不及低溫乾燥。以高溫乾燥的產品通常價格低、產量高、利潤高。
Low-temperature drying and high-temperature drying should be used in combination in the drying room, and different drying processes should be selected according to different materials. Such as tea drying, we can use low-temperature drying.
low-temperature drying and high-temperature drying in the drying room are used in stages, which can be high temperature first and then low temperature, or low temperature first and then high temperature. Not only can the drying cost be reduced, but the drying quality can also be improved. Such as grape drying and blueberry drying.
