Abstract: In one aspect, a multi-layered fertilizer includes a layer-by-layer coated fertilizer layer and a coating layer, wherein the fertilizer layer is separated from the coating layer, and one of the fertilizer layers is a fertilizer core; the fertilizer layer contains at least one of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, the coating layer is polyurea formaldehyde, which includes at least a polyurea formaldehyde having two to five carbon atoms. It can better control the release of nitrogen, phosphorus, potassium, calcium, magnesium and zinc in the fertilizer to meet the different nutrient requirements of different crops at different growth stages. The fertilizer can be prepared by a reactor, a slurry tank, a powdering tank and supporting facilities, which can control the amount of each layer of fertilizer and its position in the entire fertilizer granules according to a design procedure.

Abstract: A continuous chemical reactor may include a primary reaction unit and at least one secondary reaction unit. The primary reaction unit has a stirring device and a first temperature regulating device, and a feed inlet provided at an upper portion thereof. The secondary reaction unit is sleeved outside the primary reaction unit, and a reaction chamber is formed therebetween. By adding reaction materials to the primary reaction unit via the feed inlet and adjusting the temperature of the reaction materials by the first temperature regulating device, the reacted materials enter the reaction chamber, and the heat generated in the reaction chamber can be used to adjust the temperature of the materials in the primary reaction unit to more effectively use the heat, and the product after reaction can be discharged from a discharge hole at the lower end of the secondary reaction unit, thereby achieving continuous production.
