Abstract

The invention discloses a central bidirectional-circulating temperature control and humidity control drier. The central bidirectional-circulating temperature control and humidity control drier comprises a box body (2), a central heating system, a bidirectional hot air circulating system, a skip car and skip tray system, an automatic control system and a humidity discharging system, wherein the central heating system, the bidirectional hot air circulating system, the skip car and skip tray system and the automatic control system are mounted inside the box body (2); the humidity discharging system is mounted on the box body (2). The central bidirectional-circulating temperature control and humidity control drier disclosed by the invention is reasonable in structural design, convenient to operate, high in automation degree, high in work efficiency, capable of realizing small appearance and color difference of a dried medicinal material, uniform in drying degree, energy-saving, environment-friendly, applicable to drying of different medicinal materials and high in practicability.

Description

technical field [0001] The invention relates to a drying machine, in particular to a middle-mounted two-way circulation temperature-controlling-humidity-controlling drying machine suitable for drying and processing production of Chinese herbal medicines. Background technique [0002] Most Chinese herbal medicines are thermally unstable materials, usually requiring a longer drying time at a lower temperature. Traditional hot air circulation dryers are one-way circulation, and the blower is mostly installed on the upper end or one side of the drying chamber. Studies have shown that the wind speed distribution of the fan top-mounted tunnel dryer is very uneven. And there are two areas with relatively small wind speed in the upper part of the drying chamber. It is easy to cause uneven drying and mildew. As a result, the drying degree, appearance and color of the dried materials will be greatly different, and the rate of high-quality dried products is low. The most concentrate...
