Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer processing, in particular to an organic fertilizer drying device used for drying organic fertilizer. Background Art

[0002] Organic fertilizer refers to fertilizer made from animal excrement or animal and plant residues and other byproducts rich in organic matter as the main raw materials, which are fermented and decomposed. Organic fertilizer has the functions of improving soil, fertilizing soil, increasing soil nutrient vitality, purifying soil ecological environment, and ensuring high-quality, high-yield and high-efficiency vegetables. It is an irreplaceable fertilizer for facility vegetable cultivation. In the process of producing organic fertilizer, it needs to be dried for easy storage and transportation, and it can reduce pollution to the environment.

[0003] When processing existing organic fertilizers, the raw materials are usually placed in a heating box for baking. The water in the raw materials is heated to become water vapor and escape from the heating box. The solid matter left in the heating box is the finished organic fertilizer. However, since there is no ventilation equipment in the heating box, the water vapor in the raw materials will accumulate in the heating box, affecting the drying speed. Utility Model Content
