Pelleting equipment

Abstract

The invention discloses a pelleting equipment, which comprises a fluidization tower. The bottom part of the fluidization tower is provided with a discharge hole and the top part of the fluidization tower is provided with a gas outlet. The gas outlet is connected to the inlet of a fan via a pipeline, and the outlet of the fan is connected to the pipeline; the outlet of the pipeline is arranged at the inner part of the fluidization tower orienting downward, and the outlet faces upward. The inside of the fluidization tower is provided with a spray nozzle which is connected to a high-pressure water tank via a pipeline. The pipeline connected to the inlet of the fan is further connected with a feeding screw conveyor. The pelleting equipment disclosed by the invention has the following advantages: (1) high production efficiency; (2) the materials absorb water automatically to form granules, which can be fully disintegrated into the water after being dried.

Description

technical field [0001] The invention relates to a pesticide processing equipment for processing powder pesticides into granules, and belongs to the field of chemical machinery. Background technique [0002] With the improvement of people's living standards, in the current society that advocates green environmental protection and "sustainable development" as the theme, protecting the environment and achieving sustainable development has become a common understanding of people, and the use of agricultural products is also moving towards the direction of high efficiency and low toxicity. develop. The dosage forms of pesticide products have developed from powders and emulsifiable concentrates to environmentally friendly dosage forms such as suspension concentrates, granules, emulsions in water, and microemulsions. [0003] Water-dispersible granules are granular dosage forms that can quickly disintegrate and disperse into a high-suspension solid-liquid dispersion system after e...

AI Technical Summary

Problems solved by technology

[0005] ①Extrusion granulation, due to excessive extrusion of the original drug, this method tends to make the granules too tightly bonded. After drying, the granules are difficult to disintegrate in water, causing the pesticide to settle at the bottom of the water in the form of granules.

[0006] ②Swinging granulation is to mix, pulverize and mix the original drug and additives, and then add water. If the water is not added uniformly or the amount of water is too much, it is easy to cause part of the powder to clump and block the granulation mesh, and the production efficiency is very low. Moreover, powder agglomeration will cause serious waste of raw materials

[0007] ③Spray drying granulation, this granulation method consumes a lot of energy and is not suitable for heat-sensitive products
