Processing method of radix paeoniae alba powder

Abstract

The invention discloses a processing method of radix paeoniae alba powder. Grinding and drying equipment is adopted as processing equipment. Carrots are added from a hopper on an outer circulating pipe feeding opening, after being crushed by a centrifugal fan impeller of a main mill, the carrots enter an auxiliary mill through a first-stage inner circulating pipe, and after being crushed by a centrifugal fan impeller of the auxiliary mill, the carrots enter the main mill through a second-stage inner circulating pipe to be crushed again; materials are crushed to the required particle size in acirculating manner, powder enters a cyclone dust collector through a feed pipe of the auxiliary mill to achieve airflow drying, wet air is discharged out through a bag dust collector, the materials return to the main mill through the outer circulating pipe to be crushed and absorb water of other materials, and after the materials are crushed and dried to be qualified, a valve of an ash discharge opening of the cyclone dust collector is closed; the powder is collected by the bag dust collector, and in the crushing and drying process, airflow guided in by the inner circulating pipes impacts on akinetic energy recovery impeller to achieve kinetic energy circulating utilization; and the materials are not bonded in the crushing process, low energy consumption is achieved, the work temperatureis controllable, the property of radix paeoniae alba can be kept easily, and the defects in existing methods are overcome.

Description

technical field [0001] The invention relates to a processing method of white peony powder, which belongs to the technical field of dry crushing of materials. Background technique [0002] The medicinal part of Radix Paeoniae Alba is the perennial root, which is sour and bitter in nature and slightly cold. Dried and crushed again, the processing loss is large, the heat generated in the crushing process is accumulated, and the high crushing temperature reduces the medicinal properties of Radix Paeoniae Alba. Contents of the invention [0003] The equipment adopted in the processing method of Radix Paeoniae Alba powder of the present invention is grinding and drying equipment, and described grinding and drying equipment comprises main mill, auxiliary mill, first-level internal circulation pipe, secondary internal circulation pipe, external circulation pipe, Cyclone dust collector, bag filter, the main mill includes a centrifugal fan and a feed pipe, the outlet of the feed pi...
