Organic fertilizer usually uses chicken manure, pig manure, cow manure, and sheep manure as the main raw materials, using aerobic composting equipment, adding fermentation and decomposing bacteria, and composting technology to produce organic fertilizer.
The benefits of organic fertilizer:
1. Comprehensive nutrient fertility, soft, slow-release fertilizer effect, long-lasting and lasting stability;
2. It has the activity of activating soil enzymes, promoting root development and enhancing photosynthesis;
3. Improve the quality of crops and increase yield;
4. It can increase soil organic matter content, improve soil aeration, water permeability, and fertility retention, and reduce environmental pollution caused by chemical fertilizers.
Organic fertilizer processing process:
It is mainly divided into three processes: pre-treatment, fermentation, and post-treatment.
1. Pre-treatment:
After the compost raw materials are transported to the storage yard, they are weighed on a scale and sent to the mixing and mixing device, where they are mixed with the production and domestic organic wastewater in the factory, compound bacteria are added, and the compost moisture and carbon-nitrogen ratio are roughly adjusted according to the composition of the raw materials. Enter the fermentation process.
2. Fermentation: The mixed raw materials are sent to the fermentation tank and piled into a fermentation pile for aerobic fermentation.
3. Post-processing:
The fertilizer particles are sieved, sent to the dryer for drying, and then packed and stored for sale.
The entire process includes:
Raw material ingredients → crushing → raw material mixing → raw material granulation → granule drying → granule cooling → screening → fertilizer packaging → storage.
1. Raw material ingredients:
The raw materials are allocated in a certain proportion.
2. Raw material mixing:
Stir the prepared raw materials evenly to improve uniform fertilizer efficiency.
3. Raw material granulation:
The uniformly stirred raw materials are sent to the organic fertilizer granulation equipment for granulation.
4. Granule drying:
The manufactured particles are sent to the dryer of the organic fertilizer equipment, and the moisture contained in the particles is dried to increase the strength of the particles and facilitate storage.
5. Particle cooling:
After drying, the temperature of the dried fertilizer particles is too high and easy to agglomerate. After cooling, it is convenient to store and transport in bags.
6. Fertilizer packaging:
The finished fertilizer granules are packaged and stored in bags.
The main processing equipment of organic fertilizer:
1. Fermentation equipment: trough type stacker, crawler type stacker, self-propelled stacker, chain plate type stacker
2. Crushing equipment: semi-wet material crusher, chain crusher, vertical crusher
3. Mixing equipment: horizontal mixer, pan mixer
4. Screening equipment: drum screen, vibrating screen
5. Granulation equipment: stirring tooth granulator, disc granulator, extrusion granulator, drum granulator, and round-throwing machine
6. Drying equipment: drum dryer
7. Cooling equipment: rotary cooler
8. Auxiliary equipment: quantitative feeder, pig manure dehydrator, coating machine, dust collector, automatic quantitative packaging machine
9. Conveying equipment: belt conveyor, bucket elevator.
What are the issues to consider when purchasing organic fertilizer equipment?
1. Mixing and mixing: Even mixing of raw materials is to improve the uniform fertilizer effect content of the overall fertilizer particles. A horizontal mixer or a pan mixer can be used for mixing;
2. Agglomeration and crushing: the agglomerated raw materials that are evenly stirred are crushed to facilitate subsequent granulation processing, mainly using chain crushers, etc.;
3. Raw material granulation: feed the raw materials into the granulator for granulation. This step is the most important part of the organic fertilizer production process. It can be used with a rotating drum granulator, a roller squeeze granulator, and organic fertilizer. Granulators, etc.;
5. Screening: The fertilizer is screened into qualified finished particles and unqualified particles, generally using a drum screening machine;
6. Drying: The granules made by the granulator are sent to the dryer, and the moisture in the granules is dried to increase the strength of the granules for storage. Generally, a tumble dryer is used;
7. Cooling: The temperature of dried fertilizer particles is too high and easy to agglomerate. After cooling, it is convenient to store and transport in bags. A drum cooler can be used;
8. Coating: The product is coated to increase the brightness and roundness of the particles to make the appearance more beautiful, usually with a coating machine;
9. Packaging: The finished pellets are sent to the electronic quantitative packaging scale, sewing machine and other automatic quantitative packaging and sealing bags through the belt conveyor for storage.
