Drying equipment for production of hydroxypropyl methylcellulose

Abstract

The invention discloses drying equipment for production of hydroxypropyl methylcellulose, and relates to the technical field of production of the hydroxypropyl methylcellulose. The drying equipment comprises a cyclone dust remover, a hot air supplying module and a support framework, wherein the circumferential sides of the cyclone dust remover and the hot air supplying module are fixedly connectedwith the support framework; and one end of an air inlet of the hot air supplying module fixedly communicates with the cyclone dust remover. The drying equipment also comprises a thinning mechanism, adrying main machine and two symmetrically-arranged drying auxiliary machine, wherein the circumferential sides of the thinning mechanism, the drying main machine and the two drying auxiliary machineare fixedly connected with the support framework; and one end of a discharging hole of each of the two drying auxiliary machines fixedly communicates with the thinning mechanism. According to the drying equipment for production of the hydroxypropyl methylcellulose disclosed by the invention, through design of the hot air supply module, the thinning mechanism, the drying auxiliary machines and thedrying main machine, the device can quickly and completely perform drying operations of the hydroxypropyl methylcellulose in an automatic manner, and when the device performs drying, a static type drying structure of a conventional drying device can be changed into a circulating type multi-time drying mechanism.

Description

technical field [0001] The invention belongs to the technical field of hydroxypropyl methylcellulose production, and in particular relates to a drying equipment used for the production of hydroxypropyl methylcellulose. Background technique [0002] Hydroxypropyl methylcellulose is a semi-synthetic, inactive, viscoelastic polymer. It is often used as a lubricant in ophthalmology, or as an excipient or excipient in oral medicine. It is commonly found in various different kinds of goods. As a food additive, hypromellose can play the following roles: emulsifier, thickener, suspending agent and substitute for animal gelatin. Hydroxypropyl methylcellulose is white or off-white powder, and its production process is refined cotton pulverization-etherification and alkalization-press filtration-drying-crushing-in-factory packaging-mixing-packaging for delivery. In the production and preparation process of hydroxypropyl methylcellulose, the use of drying equipment is an indispensable...
