1.5-2 T/H Concentrated Feed Mill In Chile

Origin of the 1.5-2 t/h concentrated feed mill in Chile project

The client of this concentrated feed mill in Chile project originally ran a small livestock and poultry feed factory. Based on the prospects and profit margins of the concentrated feed market, the customer removed the original livestock and poultry feed production line and set up a concentrated feed production line in the existing factory.

The project covers a total area of approximately 1,744m2 and will produce 4,200t of concentrated feed per year after completion.

environmental protection investment

The environmental protection investment of this concentrated feed mill in Chile project is mainly used for waste gas, waste water, noise, solid waste, etc. The environmental protection investment accounts for about 0.6% of the total investment. The details of the main environmental protection investment of the project are shown in the table below.

Item Environmental protection equipment name
Exhaust gas Low nitrogen burner, ozone deodorization, bag dust collector, activated carbon adsorption, exhaust pipe
Wastewater Sewage treatment station, septic tank (anti-seepage)
Noise Shock absorbing pads, soundproof windows, etc.
Solid waste Solid waste temporary storage room, hazardous waste temporary storage room

process flow of 1.5-2t/h concentrated feed mill in Chile

  1. Activation: The strain is diluted with water, the test tube strain is activated, and then enters the Erlenmeyer flask for fermentation. The culture temperature is 28°C and the cycle is 3 days.
  2. Expansion culture: Equipment: 50-500L fully automatic fermentation tank, prepare nutrient liquid culture medium, sterilize (sterilize at 121°C for 20 minutes), the project uses 1 (1t/h) natural gas steam boiler for sterilization Treatment, natural cooling and then inoculation and culture, the secondary liquid fermentation cycle is 48 hours.
  3. Premixing treatment: After the solid matrix is soaked, the mixing ratio (rice, bran, rice bran, bean hulls, etc.) is the solid culture medium, and the fully automatic sterilization equipment is sterilized for 10 minutes at a temperature of 100°C. The material has high humidity and no particles are produced during the mixing process.
  4. Solid-liquid two-phase fermentation: Cool the solid culture medium to below 40°C, inoculate the secondary liquid for propagation. After the bacteria are cultured at room temperature, the culture temperature is 25-30°C, and the cycle is 5-7 days.
  5. Drying treatment: The materials after two-way fermentation are slightly dried by a dehumidifier, and no waste gas is produced.
  6. Crushing: Add a certain proportion of soybean meal and put it into the crusher for crushing.
  7. Mixing: After the materials are crushed and mixed by a mixer, the finished product is obtained.

Public works


Water supply

Project water includes production water (solid matrix soaking water, dilution bacterial powder water, boiler water, fermentation tank and other equipment cleaning water, laboratory water) and domestic water.



The project wastewater mainly includes production wastewater (solid matrix soaking wastewater, boiler drainage, fermentation tank and other equipment cleaning wastewater, laboratory wastewater, pure water preparation concentrated water) and domestic sewage.

The total production wastewater production of the concentrated feed mill in Chile project is 614.8t/a. After being treated by a set of underground integrated sewage treatment stations (biological treatment processes) in the factory area, it passes through the municipal sewage pipe network and is finally discharged into the sewage treatment plant for treatment.

The domestic sewage production volume is calculated as 85%, and the discharge volume is 127.5t/a. After treatment by septic tank (anti-seepage), it is discharged into the municipal sewage pipe network, and finally discharged into the sewage treatment plant for treatment.

Environmental management of concentrated feed mill in Chile


1.Waste gas control measures

Production facilities Pollution production link Pollutant type Pollution prevention facilities
Natural gas steam boiler Sterilize Particulate matter, SO2, NOx, Ringelmann blackness Low-nitrogen combustion technology, boiler + 1 15m exhaust pipe P1.
Fermenter fermentation stench Integrated exhaust in a confined space + activated carbon adsorption device treatment + 15m high exhaust cylinder P2.
Crushing and mixing Crushing and mixing particulates Gas collecting hood + bag dust collector + exhaust tube P3.

Noise sources and noise reduction measures

The noise in this concentrated feed mill in Chile project mainly comes from natural gas steam boilers, air compressors, fans, sewage treatment station supporting equipment and other equipment. The noise source intensity is 65-80dB(A).

In order to reduce the impact on the surrounding acoustic environment, the project can consider noise prevention and control measures from the aspects of sound insulation and noise reduction. Specific governance measures that can be taken are as follows:


Solid waste management measures

The solid waste generated during the operation of the 1.5-2t/h concentrated feed mill in Chile project mainly includes: waste packaging materials, sewage treatment station sludge, dust collected by dust collectors and ground dust, waste reverse osmosis membranes, waste activated carbon and domestic garbage.

General solid waste

Hazardous waste

A separate small workshop is set up for the fermentation process of the project. The odor generated during the fermentation process is exhausted through the entire closed space and then enters the activated carbon adsorption device for treatment. After treatment, it is discharged through a 15m high exhaust pipe P2.

The fermentation waste gas generated in the project is small. Based on 5kg/a, every 100kg activated carbon absorbs 20kg of waste gas pollutants to reach saturation. Therefore, approximately 25kg/a of activated carbon must be used in this project.

The 1.5-2t/h concentrated feed mill in Chile project is equipped with a 30kg activated carbon adsorption box, and the activated carbon is replaced approximately once a year. The amount of waste activated carbon produced is about 0.035t/a.

The collection and storage process of hazardous waste must be managed according to the following requirements:

Domestic garbage

The 1.5-2t/h concentrated feed mill in Chile project has a labor capacity of 10 people, and domestic waste is calculated at 0.5kg per person per day. Domestic waste is generated annually at RMB 15/a, which is regularly cleared and transported by the local environmental sanitation department.

In addition to 1.5-2t/h concentrated feed mill in Chile, Richi Machinery also exported livestock and poultry feed pellet production lines, wood pellet production lines and other projects to Chile.
