Dry-wet mixing granulation process of acetaldehyde tetramer granules

Abstract

The invention relates to the technical field of agricultural medicines, in particular to a dry-wet mixing granulation process of acetaldehyde tetrahydrate granules. The process comprises the followingsteps: mixing pregelatinized starch, flour, corn flour, fine bran, fish meal, sodium cyclamate, acetaldehyde tetrahydrate, a forming agent, a feed additive, edible oil and water according to a certain proportion; jointly adding the raw materials obtained after mixing to the inner side of heating gelatinization equipment so that the raw materials are effectively gelatinized; adding the gelatinizedraw materials into a screw extrusion pelletizer for producing screw extrusion particles; conveying the particles to a belt type drying machine through a belt conveyor to be subjected to continuous drying treatment; and conveying the dried particles into the cooling equipment so that the processes of effective cooling treatment and dry-wet mixing granulation of the raw materials are realized, thegeneration of dust can be effectively inhibited, and the temperature of the product can be effectively reduced when the product is produced, and thus the loss of effective components of the product iseffectively reduced, and the attractivity and the palatability are good.

Description

technical field [0001] The invention relates to the technical field of agricultural medicines, in particular to a dry-wet mixing granulation process for metaldehyde granules. Background technique [0002] Snails belong to the phylum Molluscs and class Gastropoda. Common species include gray snails and homotype snails. They mainly damage more than 10 kinds of cruciferous vegetables such as Chinese cabbage, Chinese cabbage, cabbage, and cauliflower, as well as beans, lettuce, and lettuce. , melons, etc., harm crops by eating plant stems and leaves, and the harm is the greatest at the seedling stage. In recent years, snails have become more and more harmful to vegetables. In order to seek new local control agents, the effect of metaldehyde granules on gray snails Control effect: Metaldehyde is a highly selective molluscicide, 6% denser, light blue in appearance, softens with water, has a special fragrance, and is very attractive. When the snail is attracted by the attractant t...

Problems solved by technology

[0004] The purpose of the present invention is to provide a dry-wet mixing granulation process for metaldehyde granules, to solve the problem that the raw materials proposed in the above-mentioned background technology will produce dust when mixing materials, and the temperature of the ring film granulation is 60-130 Celsius, and metaldehyde will depolymerize and decompose when it reaches 60 degrees Celsius, thus losing the effective cost of the product
