Mushroom residue, flat mushroom residue, and other mushroom residues are a large amount of waste generated after harvesting mushrooms in large mushroom planting bases. In some places, they are called mushroom sticks. In early processing, many mushroom planting bases used mushroom sticks as combustibles, which not only causes pollution but also wastes resources. Since the maturity of production line technology and processing technology for bio organic fertilizers, mushroom residue and other mushroom residues have been used as one of the raw materials for organic fertilizer processing.
Mushroom residue requires a fermentation and maturation process, and pure mushroom residue cannot be used as organic fertilizer. It also requires the addition of poultry and livestock manure, sludge filter mud, etc. Generally, the ratio of poultry and livestock manure to mushroom residue is 7:3, which can ensure the organic matter content and fertilizer efficiency.

Equipment and process flow for mushroom residue and mushroom rod fermentation of organic fertilizer:
1. Preparatory work: Weigh and divide the livestock and poultry manure (with a moisture content of 70%) that needs to be disposed of; Prepare microbial agents.
2. Production technology: Mix animal manure and bacterial strains in a 1:10000 ratio, and then mix them. Then reverse glue is applied to the Fangzi Sunshine Board Room, allowing solar energy to pass through the Sunshine Board to increase the room temperature of the fermentation workshop and accelerate the increase in the starting temperature of the fermentation materials. There are ventilation holes at the top to facilitate the emission of water vapor and other gases generated during material fermentation. The walls on all sides are of brick and concrete structure, with doors and windows reserved.
3. There are two fermentation tanks built in the fermentation workshop, with a length of 18-25m and a width of 2.5m. The edges of the tanks are made of bricks and covered with cement. When fermenting in a fermentation tank for 4-5 days, flip the fermented material from one tank into two tanks. It usually takes about 20-25 days from feeding to discharging.
4. Process equipment and processes. The poultry and livestock manure (such as cow manure, sheep manure, chicken manure, etc.) that has been pretreated by an organic fertilizer composting machine is directly transported to the raw material silo (or raw material mixer).
5. Transport to the disc homogenizer and control the feeding speed through a frequency converter.
6. Transported to a specialized organic fertilizer screening machine, the special design can completely solve the problem of screen adhesion.
7. The screened large particles are crushed by an organic fertilizer crusher and sent to a disc homogenizer.
8. The qualified products after screening are transported to the fully automatic packaging scale for weighing, packaging, and storage.
Basically, after working through a series of processing techniques and equipment, the organic fertilizer raw materials mixed with mushroom residue can be processed into organic fertilizer, which can be put into the market for sale as powdered organic fertilizer.
