Self-cleaning quantitative output type spray drying device

Abstract

The invention discloses a self-cleaning quantitative output type spray drying device. The self-cleaning quantitative output type spray drying device comprises a self-cleaning system, a quantitative output system, an air inlet system, a drying system and an exhaust system. Liquid materials enter the device through a drying system, viscous materials are collected to the bottom of the drying tower under the action of the rotary scraper blade and the vibration exciter in the drying process and are accurately metered and transported under the action of the screw rod, and the self-cleaning system has a rear-end dust removal function. The material recovery rate is increased, accurate metering, collection and output of materials are achieved under the action of the screw, the screw shell and the pump, the self-cleaning system solves the problem that the spray drying device adheres to the wall, the automation level of the device is improved, the labor cost of continuous industrial production is reduced, and the device is reasonable in design, easy to achieve and suitable for popularization and application. The method is suitable for further optimization and upgrading of the whole technological process.

Description

technical field [0001] The invention relates to the technical field of spray drying, in particular to a self-cleaning and quantitative output spray drying device. Background technique [0002] Spray drying is a drying process that applies fluidization technology to the drying of fluid liquid materials. It has developed rapidly in recent decades and is widely used in food, medicine, chemical and other industries. [0003] The principle of spray drying is to use the atomizer located at the top of the spray drying tower to disperse liquid materials with certain fluidity such as suspensions and emulsions into small droplets with a particle size of 10-60um, and to make the small droplets flow in a parabola The route is scattered in the drying tower and moves freely in the drying tower. Due to the high dispersion, the small mist droplets have larger free energy and surface area, and the water vapor pressure on the surface is larger than that of the plane water vapor under the same...

AI Technical Summary

Problems solved by technology

[0004] The way of collecting materials in the existing spray drying device is mainly to collect most of the granular materials by placing a material collection bottle at the bottom of the drying tower. In large-scale industrial production, the materials after spray drying need to be treated twice or directly. Filling becomes a product, which leads to the inability to accurately measure materials and consumes a lot of manpower and material resources in the transportation process. With the development of social industry and the acceleration of the automation process of intelligent machinery and equipment, the existing technology can no longer meet the needs of social and industrial development, and The problem of sticking to the wall of the spray drying device has become an important obstacle to prevent the technological progress of the industry
