Fertilizer coating process

Abstract

The invention belongs to the technical field of fertilizer coating production, and particularly relates to a fertilizer coating process, a coating machine used in the fertilizer coating process comprises a machine shell, a rotating motor and a fixed pipe; a working cavity is formed in the machine shell; a fixed pipe is fixedly connected to the interior of the working cavity; the front end face ofthe machine shell is fixedly connected with a rotating motor; a fertilizer box is fixedly connected to the position, close to the rear end face of the shell, of the right side face of the shell. According to the fertilizer coating device, rapid coating of the surfaces of fertilizer particles is effectively realized, a fertilizer layer is uniformly sprayed on the surface of the coating adhesive plate, then a coating solution is sprayed, and the problems of extrusion collision and stacking between the fertilizer particles are avoided, so that the coating thickness of the surfaces of the fertilizer particles is relatively uniform. If the coating thickness needs to be controlled, repeated coating can be carried out for multiple times, so that the coating thickness is effectively controlled, and the quality stability of the coated fertilizer is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer coating production, in particular to a fertilizer coating process. Background technique [0002] Coated fertilizers, also known as coated fertilizers and film fertilizers, are fertilizers made of semi-permeable or impermeable film substances that wrap quick-acting fertilizer particles. The purpose of the coating is to make the quick-acting nutrients inside the coated fertilizers It is released slowly to prolong the fertilizer effect, and the release rate depends on the type, thickness, particle size, fertilizer solubility, soil temperature, soil moisture content and soil microbial activity of the coating, and the thickness of the coating is the coating fertilizer One of the key points of prolonging the fertilizer effect is that different crops have different requirements for the fertilizer effect time. In order to make the fertilizer effectively adapt to different crops and make full use of the...

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art and solve the prior art, when coating the fertilizer, a coating machine needs to be used. The coating machine of the prior art adds the coating solution to the fertilizer particles, and then stirs the fertilizer particles , so that the surface of the fertilizer particles adheres to the uniform coating solution. In addition, through the high-pressure tank, the high pressure of the high-pressure tank sprays the coating solution inside the high-pressure tank through the external nozzle and sprays it on the surface of the fertilizer particles to achieve The surface of the fertilizer particles is quickly coated, but the fertilizer particles in the above method are stacked and squeezed on each other. During the coating process, the fertilizer particles collide with each other, and the film thickness uniformity of the coating solution on the surface of the fertilizer particles is poor. , and it is difficult to control the thickness of the coating, which causes problems such as difficult control of the fertilizer effect time of the coated fertilizer. The present invention proposes a fertilizer coating process
