Drying device for algal protein feed preparation

Abstract

The invention discloses a drying device for algal protein feed preparation, relates to the technical field of feed preparation and aims to improve an existing drying device so as to improve the dryingquality of the existing drying device. According to key points of a technical scheme of the drying device, a plurality of conveying belts are arranged in the horizontal direction in a drying box, theconveying belts are distributed in the vertical direction, the conveying directions of every two adjacent conveying belts are opposite, the conveying belts which perform conveying clockwise deflect leftwards, and the conveying belts which perform conveying counterclockwise deflect rightwards; compression rollers are arranged above each conveying belt, the rotating linear velocity of the compression rollers is equal to the conveying velocity of the conveying belt, and scraping plates located below ends of the conveying belts are arranged in the drying box; and an air supply pipe used for supplying air from a feeding port to a discharging port is arranged in the drying box, and a heating pipe is arranged at one end, close to the feeding port, of the air supply pipe. The drying device achieves the effect of improving the drying quality.

Description

Technical field [0001] The invention relates to the technical field of feed preparation, in particular to a drying device for preparing seaweed protein feed. Background technique [0002] There are as many as tens of thousands of algae in the ocean, including 10 phyla of Chlorophyta, Phaeophyta, Cyanophyta, Rhodophyta, etc. These algae are rich in seaweed polysaccharides, protein, fat, vitamins, minerals, and Physiologically active substances with special effects are a raw material library for food, feed and medicine. [0003] The existing Chinese patent with application number CN200410024541.4 discloses a method for processing seaweed protein feed, which includes the following steps: selecting kelp residue as the main raw material, calcifying the kelp residue to obtain calcified flocs, and combining the calcified flocs Dehydration, drying, and pulverization are performed to obtain the main raw material powder as the primary finished product; and appropriate seaweed is selected as...

Problems solved by technology

[0004] In the above scheme, it is necessary to perform multiple drying operations on various intermediate products, which has a relatively large impact on product quality and production efficiency. Therefore, how to improve the quality of drying and crushing is a problem that needs to be studied

[0005] The existing drying technology transfers the material to the high-temperature box through the conveyor belt, and evaporates the moisture in the material through high temperature, but this method only uses high temperature to dry the material, the drying efficiency is low, the drying effect is not good, the processing time is short, and the material is not dry enough. Thorough; long processing time will easily lead to browning of seaweed protein raw materials through Maillard reaction, resulting in a serious decline in product quality
