Biological Fertilizer Production

Parameter Selection

The whole process can be simply divided into four processes: pretreatment, primary tank fermentation, secondary tank aging, powdered organic fertilizer production and granular organic fertilizer production.

The finished material goes into the horizontal crusher at the same time for grinding. The crushed material is sent to the screening machine through the belt conveyor for screening, the material on the screen is returned to the crushing process for crushing, and the material under the screen meets the standard and is packed into the finished product.

Product Description

Biofertilizer production line have complete nutritional elements, which can improve soil and improve soil compaction caused by the use of fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. After the beneficial microorganisms in bio organic fertilizers enter the soil, they form a symbiotic and proliferative relationship with the microorganisms in the soil, inhibiting the growth of harmful bacteria and transforming them into beneficial bacteria. They interact and promote each other, playing a synergistic role in the population. During the growth and reproduction process, beneficial bacteria produce a large amount of metabolic products, promoting the decomposition and transformation of organic matter, and can directly or indirectly provide various nutrients and stimulating substances for crops, Promote and regulate crop growth. Improve soil porosity, permeability and exchangeability, plant survival rate, and increase beneficial bacteria and soil microorganisms and populations. At the same time, the advantage of beneficial microbial communities in the formation of crop roots is that they can inhibit the proliferation of harmful pathogens, enhance crop resistance and disease resistance, and reduce the disease index of continuous cropping crops. Continuous application can greatly alleviate continuous cropping obstacles. Reducing environmental pollution, safe and non-toxic for humans, livestock, and the environment, is an environmentally friendly fertilizer.

Tank fermentation process:

The whole process can be simply divided into four processes: pretreatment, primary tank fermentation, secondary tank aging, powdered organic fertilizer production and granular organic fertilizer production.

Pretreatment: After the compost raw materials are transported to the yard, they are weighed by the scale and sent to the mixing mixing device, mixed with the production and living organic wastewater in the plant, added microbial strains, and the fertilizer moisture and carbon nitrogen ratio are coarse adjusted according to the raw material composition, and then mixed into the tank fermentation process.

Single tank fermentation: The mixed raw materials are sent to the primary fermenter by belt conveyor, and evenly laid to the tank through the distributor. The fan is used to force ventilation from the bottom of the fermentation tank to provide oxygen, and the pile is turned over at the same time to control the fermentation temperature at 50 ~ 65℃ for aerobic fermentation. The fermentation cycle of this project is 8 days, with one pool of raw materials entering and one pool of semi-finished products leaving every day.

After the fermented semi-finished product is discharged, it is ready to enter the next process. Secondary aging: The material output from the fermenter is sent to the aging tank by belt conveyor. When the moisture content of the material drops below 40%, it will be aged for more than 15-20 days. During the aging period, the trough turning machine will be used to turn the material. Thermophilic microorganisms gradually began to dominate, and further decomposed residual organic matter that was difficult to decompose. However, the activity of microorganisms generally declined, the calorific value of the pile decreased, the temperature decreased, the organic matter tended to be stable, the oxygen demand was greatly reduced, and the compost entered the post-maturing stage, when the temperature stabilized at 40℃ and the moisture dropped to 30%, the compost matured and humified.

Production process requirement:

1. The general dosage of bacterial strains is 0.2% -0.5%.

2. Raw materials and requirements: main materials: fruit dregs, dry bagasse, edible fungus dregs, distiller's grains, brewer's grains, sugar dregs, vinegar dregs, starch dregs, cassava dregs, citric acid dregs, soy sauce dregs, monosodium glutamate dregs, powder dregs, bean curd dregs, medicine dregs, oil dregs, Youbing (Deep-fried round and flat dough-cake) dregs, bran, cotton rapeseed dregs, moldy feed, sludge, sugar refinery brewery dregs, slaughtering leftovers, hogwash (swill) water, leftovers, human and animal feces and other bulk materials.

3. Auxiliary materials and requirements: various crops such as straw, leaves and weeds, melon vines, rice straw, pine shells, peanut shells, sawdust, husk powder, and bran can be dried, crushed, and high carbon.

4. Raw and auxiliary material ratio: main material: auxiliary material=5:1-3:1.

5. The moisture content should be controlled between 60% and 65%, and the material should be grasped by hand to form a ball that just flows out of the water.

6. Mix all bacterial strains, main ingredients, and auxiliary materials evenly as required.

7. The environmental temperature is above 15 ℃, and the amount of material piled up at a time shall not be less than 4 square meters. The pile shall be made into a pile with a width of 1.5-2m, a height of about 0.6m, and an unlimited length, and air holes shall be punched through the pile with a rod.

8. When the stack temperature rises to 50 ℃, it begins to tip over once a day. If the stack temperature exceeds 65 ℃, it will tip over again. The temperature should be controlled below 70 ℃, and too high a temperature can affect nutrients.

9. Maturity sign: The pile temperature decreases, the material is loose, there is no original odor of the material, there is a slight ammonia smell, and white hyphae are produced inside the pile.

10. Mature raw fertilizer: directly used to produce commercial organic fertilizer, bio organic fertilizer, organic inorganic compound fertilizer, bio organic inorganic compound fertilizer, etc.
