When herbal medicines are dried using a mesh belt dryer, drying temperature control is crucial to maintaining the quality and efficacy of the herbal medicines. Generally speaking, the drying temperature of herbal medicines should be controlled between 60℃ and 80℃. The exact temperature depends on the type and characteristics of the herb. For example, Chinese herbal medicines containing volatile oils are suitable for drying at a temperature of 45-65°C, while juicy fruits are suitable for drying at a temperature of 65-90°C.
During the drying process, in addition to temperature control, humidity control also needs to be paid attention to. Control the humidity by adjusting the ventilation volume to ensure that the herbs are evenly heated during the drying process and avoid over-drying or over-humidity.
In addition, drying time is also an important factor affecting the quality of herbal medicines. Generally speaking, the drying time of herbs needs to be controlled within 48 hours, and the specific time depends on the type of herbs and the efficiency of the drying equipment. During the drying process, the status of the herbs needs to be checked regularly to ensure that their dryness meets the requirements.
In short, when using a mesh belt dryer to dry herbal medicines, it is necessary to comprehensively consider the type, characteristics and performance of the drying equipment, and reasonably control the drying temperature and humidity, as well as the drying time, to ensure the quality and efficacy of the herbal medicines. . At the same time, in order to ensure the drying effect and stability, the drying equipment needs to be repaired and maintained regularly.
