The advantages and disadvantages of organic fertilizer fermentation mode are as follows
At present, organic fertilizer fermentation methods are: tank, trough, stack and tank heating.
1. Tank fermentation: advantages: strong controllability, good fermentation effect, low investment cost, and the cycle is generally 7-10 days. Disadvantages: sufficient space is needed and the cost of civil engineering is relatively high.
2. Tropugh fermentation: advantages: strong controllability, good fermentation effect, low cost of Zi input, and the cycle is generally 7-10 days. Disadvantages: sufficient space is needed and the cost of civil engineering is relatively high.
3. Stacking fermentation: advantages: the original fermentation method, the fermentation effect is general, the cycle is generally 10-15 days. Disadvantages: large floor area.
4. Tank heating fermentation: advantages: stable sealing performance, strong mobility, good fermentation effect, the cycle is generally 3-5 days. Disadvantages: high equipment investment cost.
The fermentation equipment of organic fertilizer includes: self-propelled compost windrow turner, spiral compost windrow turner, trough type compost windrow turner and chain type compost windrow turner. 
Animal manure processing equipment can process animal manure into organic fertilizer in a short time, so it is also called organic fertilizer production equipment. When the equipment system is working, the feces of livestock and ingredients are sent to the mixing mixer according to the specified proportion for mixing and mixing to make it uniform. The mixture is further mixed by the screw conveyor and sent to the host pressurized mixer. The temperature of the mixture in the machine is raised by the pressure friction of the pressurized mixer, killing or inhibiting low-temperature bacteria, killing ascaris eggs and harmful bacteria, and then providing appropriate air and water, Create suitable conditions for thermophilic bacteria fermentation, complete the rapid fermentation, then crush and loosen it through a grinder, and finally send it to the storage yard for stacking to become organic fertilizer.
