The invention discloses a batch-type granular fertilizer controlled-release coating device and a production process. The batch-type granular fertilizer controlled-release coating device comprises a material distribution bin, a conveyor belt, a material distribution hopper, stirring tanks, a hot air device, a transfer material bin and a vertical elevator, the bottom of the material distribution hopper is provided with two material outlets, and granular fertilizer can be uniformly distributed into the two stirring tanks by rotating a movable cover plate. The stirring efficiency in the stirring tanks is guaranteed, heat loss in the stirring tanks is prevented through baffles, and therefore the surfaces of fertilizer particles can be evenly wrapped with a polymer coating agent, the production quality of the granulated fertilizer is guaranteed, the decomposition and release time of the fertilizer is prolonged through coating, and the utilization rate of fertilizer nutrients is increased, and the purpose of prolonging the shelf life of the fertilizer and promting increase in agricultural output. The coating agent used in the production process of the device does not need to be conveyed through a pipeline, the link of cleaning with a special organic cleaning agent is omitted, the production cost is reduced, organic dissolution is prevented from polluting the environment, and the device is low in investment, quick in effect and easy to operate.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to an intermittent granular fertilizer controlled-release coating device and a production process. Background technique [0002] Fertilizers are fertilizers made by chemical and physical methods that contain one or several nutrients needed for the growth of crops. Also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc., are not edible. They have the following common characteristics: simple ingredients, high nutrient content; fast fertilizer effect, strong fertilizer; some fertilizers have acid-base reaction; generally do not contain organic matter, and have no effect of improving soil and fertilizing. There are many types of chemical fertilizers, and their properties and application methods are quite different. [0003] By coating, wrapping, adding inhibitors, etc., the de...
