A kind of drying equipment for the production of hydroxypropyl methylcellulose

Abstract

The invention discloses a drying device used for the production of hydroxypropyl methyl cellulose, and relates to the technical field of hydroxypropyl methyl cellulose production. The invention includes a cyclone dust collector, a hot air supply module and a support frame, the peripheral sides of the cyclone dust collector and the hot air supply module are fixedly connected with the support frame, and one end of the air inlet of the hot air supply module is fixedly connected with the cyclone dust collector; The refining mechanism, the drying main machine and the two symmetrically arranged drying auxiliary machines, the refining mechanism, the drying main machine and the peripheral sides of the two drying auxiliary machines are all fixedly connected with the supporting frame, and one end of the discharge port of the two drying auxiliary machines is fixedly connected with the refining mechanism. . Through the design of the hot air supply module, the refinement mechanism, the drying auxiliary machine and the drying main machine, the present invention enables the device to quickly complete the drying operation of hydroxypropyl methylcellulose in an automated manner, and the device becomes traditional when drying. The static drying structure of the drying device is a cyclic multiple drying mechanism.

Description

technical field [0001] The invention belongs to the technical field of hydroxypropyl methylcellulose production, and particularly relates to a drying device used for the production of hydroxypropyl methylcellulose. Background technique [0002] Hydroxypropyl methylcellulose is a semi-synthetic, inactive, viscoelastic polymer, often used in ophthalmology as a lubricant, or as an adjuvant or excipient in oral drugs, commonly found in various Different kinds of goods. As a food additive, hypromellose can play the following roles: emulsifier, thickener, suspending agent and a substitute for animal gelatin. Hydroxypropyl methylcellulose is white or off-white powder, and its production process is refined cotton crushing—etherification and alkalization—filtering—drying—crushing—packing in the factory—mixing—packing and leaving the factory. In the production and preparation process of hydroxypropyl methyl cellulose, the use of drying device is an indispensable step, and hydroxypro...
