Spray drying device for preparing protein small peptide chelated zinc

Abstract

The invention provides a spray drying device for preparing protein small peptide chelated zinc, which comprises a box body mechanism, an upper cover mechanism, a base mechanism and a wall scraping mechanism, the upper cover mechanism and the base mechanism are fixedly connected to the upper end and the lower end of the box body mechanism respectively, and the upper cover mechanism and the base mechanism form a closed container with the box body mechanism; an air heater is fixedly mounted on the side wall of the box body mechanism and is communicated with the box body mechanism; the lower end of the upper cover mechanism is rotationally connected with a rotating mechanism, and atomization mechanisms are installed on the two sides of the rotating mechanism. According to the device, the infrared distance meter fixedly installed on the upper cover body is used for detecting the distance between the wall scraping mechanism and the upper cover body, the feeding amount of materials is controlled according to continuous changes of the shortest distance, then the atomization amount in the box body mechanism is controlled, and the situation that in the drying process, drying is not complete due to too much atomization amount, and drying is not complete can be effectively prevented. The powder which is completely dried is attached to the inner wall of the box body mechanism, so that the drying efficiency of the device is kept to the maximum.

Description

technical field [0001] The invention relates to the technical field of spray drying equipment, in particular to a spray drying device for preparing small protein peptide chelated zinc. Background technique [0002] Spray drying is a drying process in which the raw material liquid is put into an atomizer to separate into droplets, and hot air or other gases are in direct contact with the droplets to obtain powder-shaped products. Spray drying technology has a very special purpose, which greatly simplifies and shortens the process and time of the semi-finished or finished product of the extract, and greatly improves the production efficiency. In the prior art, when preparing protein small peptide chelated zinc, it is usually necessary to use The protein small peptide chelated zinc extract in the spray drying tower is dried. Since the protein small peptide chelated zinc in the state of nanoparticles is small in size, it is easy to attach to the inner wall of the spray drying to...

Problems solved by technology

Spray drying technology has a very special purpose, which greatly simplifies and shortens the process and time of the semi-finished or finished product of the extract, and greatly improves the production efficiency. In the prior art, when preparing protein small peptide chelated zinc, it is usually necessary to use The protein small peptide chelated zinc extract in the spray drying tower is dried. Since the protein small peptide chelated zinc in the state of nanoparticles is small in size, it is easy to attach to the inner wall of the spray drying tower, and it is inconvenient to clean and it will reduce the efficiency of the spray drying device. The drying efficiency also increases the waste rate of the drying device. At the same time, because the extract is easy to form a vortex on the edge of the atomizing nozzle, the incompletely dried extract is easy to adhere to the atomizing nozzle and cause blockage.
