For a long time, RICHI has accumulated rich experience in the pellet production lines construction, and has established cooperative relations with thousands of customers in more than 130 countries and regions, providing complete solutions for animal feed mill plants, aqua feed production lines, wood pellet production line, and agricultural waste biomass pellet production lines, organic fertilizer production line, cat litter production lines, etc., and provide services covering the entire life cycle of products.
The client of this organic fertilizer business project, Qingdao Chunyao Environmental Technology Co., Ltd., is an organic fertilizer company for agro fertilizer products, invested 5 million yuan (785,000 USD) to lease local land to build an organic fertilizer production project. The leased land covers an area of 840m², and the main construction content is a new factory building with a construction area of 840m².
After the agro fertilizer company project is completed and put into production, it can produce 4,406 tons of fertilizer per year. The main raw materials required for the agriculture fertilizer company project are livestock manure from farms and sewage sludge from domestic sewage treatment plants.
The agro fertilizer products of the bio fertilizer company project mainly produce farmland fertilizers, tobacco leaf fertilizers and garden fertilizers based on actual orders. The sewage treatment plant sludge is only used for the production of garden fertilizers, not as raw materials for the production of farmland fertilizers and tobacco leaf fertilizers.
The sludge is provided by the local sewage treatment plant, and the rest of the raw materials are purchased locally; the organic fertilizer granulator machine uses extrusion granulation, no heating, and no boiler.
The main raw and auxiliary materials of the bio fertilizer company project are detailed in the table below:
|Name||Dosage||Maximum storage capacity||Remarks|
|Sludge||12960t/a||1300t||Purchased from a water plant|
|Chicken manure and pig manure after fermentation||8640t/a||900t||Procured from the farm, in bulk|
|Note: The moisture content of chicken manure and pig manure is 80%. Sludge moisture content is 80%.|
The product of this pig chicken manure fertilizer complete production line project is fertilizer. The main products and production scale are shown in the following table:
|Note: The evaporation water capacity of the heating barrel of the organic fertilizer company project is 6000kg/h, and the 3 feeding tanks have 24t water content of 19.2t, so 3 batches can be processed a day, then the raw material processing capacity = 24t×3×20 %×300=4320t. In addition, if 2% water is added to the granulation process, the annual output of fertilizer=4320+4320×2%=4406t|

The organic fertilizer company project builds a new closed production workshop. The organic fertilizer production line workshop is divided into feeding tanks, belt conveyors, heating barrels, pelletizers, and packaging stations from west to east.
Three feeding tanks in the feeding area have a radius of 0.85m, a height of 1.5m, and an area of about 9m2; the belt conveyor is 3m in length, the heating barrel is 8m in length, and the diameter is 1.8m; the pig chicken manure organic fertilizer machine is 3m in length and 2m in width, the packaging station has a length of 5m and a width of 3m.
The total length of the pig chicken manure organic fertilizer production line is 24.1m, the width is 4.7m, and the height is 1.8m. The bio fertilizer company project workshop has a length of 60m, a width of 14m, and a height of 8m. Therefore, the organic fertilizer company project's fertilizer production line is feasible to install in the workshop.
|Organic fertilizer equipment name||Model||Quantity|
|Heating barrel||Φ1.8m, length 8m||1|
|Organic fertilizer pellet machine||/||1|
The water used for the 1.5-2tph small pig chicken manure organic manure production plant project is mainly water used for granulation, preparation of biological deodorant and domestic water for employees.
After the organic fertilizer company project's dried dry powder enters the granulator, it needs to add 2% water to be extruded and granulated. The amount of dry powder is 4320t, and the amount of water added for granulation is 86.4m³/a.
In this organic fertilizer company project, the spraying of biological deodorant is used in the workshop to reduce odor pollution. The water consumption for the preparation of biological deodorant is about 48m3/a. The bio fertilizer company project has a labor quota of 10 people.
There is no boarding and lodging in the organic fertilizer company factory. The domestic water quota refers to the "Building Water Supply and Drainage Design Code" (GB50015-2003 (2009)), the domestic water quota of industrial enterprises and the "Urban Resident Water Consumption Standard" (GB/T50331) -2002), the water consumption standard is calculated as 50L/person·day, and the annual working day is 300 days, the domestic water consumption is 150m³/a.
To sum up, the total water consumption of the bio fertilizer company project is 284.4m³/a, which is uniformly supplied by the municipal water supply pipe network.
All the biological deodorants of the bio fertilizer company project are lost and are not discharged; all the water added for organic fertilizer pellet equipment granulation enters the product; the project wastewater is mainly the domestic sewage of the employees.
The amount of domestic sewage generated is calculated at 85% of the water consumption, and the amount of domestic sewage is 127.5t/a. After the domestic sewage is collected in the septic tank in the organic fertilizer pellet plant area, it is regularly cleaned out for composting.
The electricity for the chicken manure pig manure organic fertilizer production project is provided by the municipal power supply network.
The production heat of the bio-organic manure fertilizer production line project adopts electric heating.

Purchased chicken manure, pig manure, and water plant sludge will not fall to the ground after being transported by tanker to the factory, and will not be stacked in the fertilizer manufacturing plant, but will be directly pumped into the feeding tank through a pipeline connection.
The feeding process Airtight. Chicken manure and pig manure are purchased from farms around the plant, and sludge is purchased from water plant sludge.
After batching in a certain proportion through the automatic metering system, it is conveyed to the heating barrel by a belt. After the materials in the heating barrel are fully stirred, they are continuously heated.
The temperature is controlled at 60°C. The heating method is electric heating. The raw materials with a moisture content of 80% are completely dried, and the process from feeding to discharging is completely closed.
The dried material in the heating barrel is in a dry powder state, and the discharge port of the heating barrel is connected with the conveyor belt of the chicken manure organic fertilizer machine granulator, and the dry powder material is automatically transported to the fertilizer granulator machine.
The metering system of the organic fertilizer pellet making machine controls the amount of water, adding 2% of water and the dry powdery materials, fully mixing them, and extruding them into pig chicken fertilizer pellets.
The granular fertilizer is discharged from the discharge port of the animal manure pellet granulator, and the processed pelleted chicken pig manure is bagged for sale. The product of the agriculture fertilizer company project will not be delivered to the ground and will be transported out of the car after being bagged.
The raw materials and products of the agriculture fertilizer company project are not piled up in the factory, so that they are Nissan Nissan. The gas outlet of the feeding tank of the agriculture fertilizer company project is connected to the gas collecting pipeline, and the gas collecting hood is set above the outlet of the heating barrel.
The malodorous gas generated during the feeding, stirring and drying process is collected through the pipeline and gas collecting hood to a set of activated carbon adsorption device after treatment, the exhaust gas is discharged through a 15m high exhaust tube.
