CAC membrane composting turner process
- Ground hardening
After hardening the site with concrete, and leaving a slope of 5‰ in the length to harden, the pipe laying part is grooved with a width of 20cm and a depth of 20cm. If it is not hardened, the machine cannot work normally (forklifts will damage the ground when they are building piles or clearing manure after fermentation, forming a ditch, which is easy to accumulate water), and at the same time, the aeration pipes are easily damaged (it is easy to remove the pipes during mechanical operations). damage, it needs to be replaced continuously, resulting in economic losses).
- Retaining Wall Construction
In order to make the fermentation pile easier to form, the material to be fermented more evenly, to prevent rainwater from pouring back and also to facilitate the composting operation of forklift trucks, each membrane composting equipment should build 2 retaining walls with a height of 1.0 meters.
- Pipe laying
Assemble the various parts of the aeration pipe and make holes in the pipe.
- Install intelligent control system
Connect the sensor to the control cabinet and power up the device.
- Build a heap
The excipients such as manure and straw are mixed evenly according to the appropriate proportion of composting, and the moisture content is controlled at about 65%.
Stack the mixed material on the aeration pipe, with a height of 1.8-2 meters, and then start to lay the membrane body. In the process of laying the membrane body, the edge pressing treatment is carried out. Use a crimping bag or a compactor to compact the edge of the nanomembrane to keep the edge air-tight.
- Sensor installation
There are two mounting holes on the sides of the membrane to insert the sensor into the stack.
- High temperature aerobic fermentation process
After the stacking material is pretreated and stacked, it will enter the aerobic fermentation process. Due to the addition of bacterial agents, aerobic microorganisms will accelerate the decomposition of organic matter in the material, and the aerobic decomposition will proceed rapidly. It rises quickly, usually for 2-3 days, and the temperature of the pile rises from normal temperature to about 60 °C.
Keep the temperature at about 60°C for 7 days (if the temperature of the heap exceeds 75°C, it must be cooled in time to make it down to about 70°C), and the continuous and stable high temperature can completely inactivate the pathogenic microorganisms in the material, and remove the eggs and weed seeds. Completely kill and achieve harmless treatment. After the high temperature fermentation is completed, the material is completely odorless; after entering the high temperature aerobic fermentation for 12 days, the material is completely decomposed and meets the harmless requirements. After 15-20 days, the fermentation is complete. Fermented and decomposed organic fertilizers can be directly applied to the soil to increase soil organic matter content, improve crop resistance, or add corresponding substances as needed to sell as commercial organic fertilizers.
- Aging process
After the nano-film high-temperature aerobic fermentation is completed, the moisture content of the material can generally be reduced to about 40%. Use a forklift to transport the fermented materials to the aging workshop for aging. The purpose of aging is to further decompose and stabilize the undegraded macromolecular organic matter in the material to meet the needs of subsequent products. The aging cycle is generally 7-14 It can also be flexibly adjusted according to product needs.
Powdered Organic Fertilizer Production Line
Pulverization: In the process of fermentation and aging, the decomposed clinker has many large particles, which need to be pulverized by a pulverizer, and then enter the screening.
Screening: There are plastic bags, bricks and other impurities in the crushed rotted clinker, which need to be screened by a drum sieving machine, and the qualified powdery rotted clinker is left for the next process.
Dynamic batching: the qualified rot clinker after screening, because the raw materials are different, the content of organic matter and mineral elements in the material is different, through the test, the corresponding substances are added to the dynamic batching machine for those with low content of organic matter and mineral elements, and then enter the next process.
Stirring: After dynamic batching, the materials and nutrients are processed by a double-shaft mixer
