Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer coating equipment, in particular to an organic fertilizer production coating equipment. Background Art

[0002] As the main way of livestock and poultry manure fertilizer utilization, organic fertilizer has the characteristics of improving soil and enhancing soil nutrient vitality. The processing technological process of organic fertilizer includes processes such as pretreatment (raw material crushing and mixing), fermentation and composting, crushing, screening, adding bacteria and coating, and packaging. Coating coats a semi-permeable or poorly soluble film on the surface of fertilizer particles to slowly release nutrients, so as to achieve the effect of controlled release of nutrients according to the growth situation of crops. There are many types of coating materials, mainly including sulfur, polymer, resin, paraffin, silicon-based materials, etc. These film-forming substances wrap on the surface of water-soluble granular fertilizers to avoid direct contact between fertilizers and soil and crop roots. Water enters the film to dissolve nutrients, the osmotic pressure rises, promoting nutrients to diffuse through the film into the soil solution, or slowly release outward through small holes in the film, and are continuously absorbed and utilized by crops, reducing the loss of soluble nutrients such as phosphorus loss and ammonia volatilization loss, which is beneficial to improving fertilizer utilization rate. In the prior art, in order to improve the nutrient slow-release effect of fertilizers, composite film fertilizers are designed, that is, multiple layers of films with different properties are formed on the surface of fertilizers to form a difference in nutrient slow-release speed. The coating machine is a key equipment for adding bacteria and coating and determining the granulation properties of granular organic fertilizers. At present, in the actual production process, drum-type coating machines are widely used. The drum-type coating machine processes film layer powder materials, nutrient solutions, and adhesive solutions added to the drum onto the surface of fertilizer particles into a film by rotation. The existing drum-type coating machines have a single-stage design of the drum, which often does not support the composite film process, and the mechanism for adding materials is single, and it is impossible to add adaptive nutrient solutions or film layer powder materials according to the requirements of the composite film process for different film-forming stages.
