Embodiment Construction

[0014] Referring to the accompanying drawings, one-step granulation of traditional Chinese medicine drying production process: First, the quantitatively dried auxiliary material particles are added from the particle outlet [6], and enter the drying chamber [7] from the upper part, and the filtered air is heated by the heater and then from the hot air inlet. [3] Enter the drying chamber [7]; after the hot air enters, the added dry particles will form a fluidized bed, and the auxiliary particles will be heated to the specified temperature to start the air compressor. After the liquid medicine is pressurized by the compressed air in the storage tank, The nozzle [1] is mixed with compressed air and atomized, and the sprayed liquid medicine is absorbed in the material of the fluidized bed; at the same time, the motor [5] is driven to drive the stirring blade [2] through the stepless speed control box [4] to stir The leaves are constantly stirred, and the particles in the fluidized b...

Abstract

A drying and producing process of traditional Chinese medicine through one-step granulating is mainly characterized in that quantitative dried auxiliary material particles are added from a particle outlet and enter a drying chamber from a hot air inlet after heated by filtered air; the added dried particles form a fluidized bed through hot air; after the auxiliary material particles are heated to a designated temperature, a pressurized liquid medicine is mixed and atomized with compressed air through a nozzle in a storage tank; the sprayed liquid medicine is absorbed in materials of the fluidized bed, an agitating blade agitates the mixture continuously, particles are increased gradually on a fluidized bed layer dried by the hot air to the particle outlet; and finally, the particles are discharged out of a drying tower. According to the drying and producing process of traditional Chinese medicine through one-step granulating, a spray drying method, a fluid bed drying technique and an agitating method are combined, a one-step drying and granulating process of a traditional Chinese liquid medicine is realized.

Description

technical field [0001] The invention relates to a production process for drying and granulating traditional Chinese medicinal liquid by adopting spray drying and fluidized bed drying technologies. Background technique [0002] At present, the thorny problem in the production of traditional Chinese medicine is the drying and granulation of traditional Chinese medicine liquid, especially the dry granulation of traditional Chinese medicine extract or lower concentration. In addition to heat sensitivity, most of the extracts still have unmanageable viscosity, and they will go through a viscous change process during the drying process from liquid to solid. Directly drying Chinese medicine liquid into dry granules is a mainstream direction of Chinese medicine processing. The traditional commonly used method mainly uses spray drying, which takes a long time in the drying process, the efficiency is relatively low, and the particles are too fine. [0003] The use of special one-ste...
