Technical Field

Belongs to the field of traditional Chinese medicine processing, and particularly relates to a device for steaming/de-enzyming and drying picked traditional Chinese medicines.

Background

The Chinese medicinal materials are important components of Chinese medicine treasury and play an important role in human health for thousands of years. Due to the characteristics of nature, small toxic and side effects and the like, the traditional Chinese medicinal materials have obvious advantages in treating stubborn diseases and chronic diseases for a long time and gradually move to the world.

The collected Chinese herbal medicines and Chinese herbal medicines are not only used as fresh medicines but also dried and processed for storage. The drying process is an important link influencing the quality and economic value of the traditional Chinese medicinal materials, and the drying effect directly influences the use, quality and appearance of the product. The traditional Chinese medicinal materials of grass, leaves, stems and the like of plants are subjected to processing procedures including steaming, drying and the like before use, and a great number of medicinal materials need to be subjected to enzyme deactivation.

The 'de-enzyming' is an important link of the primary processing of the medicinal materials and influences the properties and the quality of the medicinal materials.

At present, the main processing methods of the traditional Chinese medicinal materials comprise: steaming, generally, a steamer is placed on a boiling water pot for steaming, steam generated by a high-pressure boiler directly acts on the traditional Chinese medicinal materials for steaming, and the traditional Chinese medicinal materials are directly placed in an aluminum pot for boiling; the method for deactivating enzyme in the producing area mainly comprises the step of directly acting steam generated by a high-pressure boiler on the Chinese medicinal materials for deactivating enzyme. In addition, the high-temperature high-humidity gas jet impact technology can also be used for steaming/de-enzyming traditional Chinese medicinal materials, but the technology can only steam one layer of materials once, and the processing efficiency is too low. In the drying aspect, part of farmers still adopt a natural airing or shade drying mode, but the required period is long, and the mildewing is easily caused; drying in a drying room used by cooperative society requires a large amount of coal resources at first, and the produced sulfides remain in the Chinese medicinal materials.

The steaming/water-removing and drying of the traditional Chinese medicinal materials are completed in stages, materials are generally required to be transferred from steaming equipment to drying equipment for continuous operation, the labor and the processing time are consumed in the actual production, if the continuous processing of the steaming equipment and the drying equipment can be realized, firstly, the labor and the time can be saved, and the waste heat after the steaming can be utilized in the early stage of drying, so that the energy consumption is reduced. The high temperature and high humidity gas jet impact technology is a novel high efficiency steaming/enzyme deactivation processing technology, and the gas jet impact drying technology can reduce the boundary layer on the surface of the material so as to increase the heat transfer coefficient, and the effect is superior to that of hot air drying.

Chinese patent CN201210057429.5 discloses an incline charging tray formula gas jet impact dryer, the hot gas flow is through left and right sides cavity evenly distributed and jet to the material surface of placing in the slope tablet, the material loading is big, it is even to be heated, but this equipment only can regard as the desiccator to use and air duct system is one-way circulation system, the charging tray angle needs to be adjusted manually, humidity only can adjust through the vapor that the material produced in drying process in addition, there is the function singleness, the operation is hard, or occupy defects such as the place is great.

Therefore, the continuous processing equipment and the processing method of the Chinese medicinal materials are provided aiming at the problems.
