Auxiliary facilities of 125 t/h compound feed mill

Public works

The water used in the factory comes from the municipal water supply network for production and domestic use, which can meet the needs of this 125t/h compound feed mill project.

Domestic water

There are 80 employees. There is a canteen and accommodation in the factory. The water consumption for employees is calculated as 120L/person·d, and the water consumption in the canteen is calculated as 25L/person·meal. The domestic water consumption is 11.6m3/d, that is, 3480m3/a.

Domestic sewage generated amount is calculated based on 80% of the water consumption, then the domestic sewage production volume is 9.28m3/d, that is, 2784m3/a. After being pre-treated by grease traps and septic tanks, domestic sewage enters the sewage treatment plant through the municipal sewage pipe network for treatment.

The 125t/h compound feed mill project is equipped with a 3t/h gas boiler, the steam supply is 3t/h, the boiler operating time is calculated as 1350h/a, the steam generated by the boiler is used for direct heating, and direct heating consumes steam. This evaluation is based on the total amount of steam generated.

Consumption calculation, steam production is 13.5t/d, 4050t/a. Soft water needs to be used when boiler water is used. The soft water production process is ion exchange resin method. The treatment scale is 4m3/h. The preparation rate is calculated as 75%.

When preparing boiler soft water required amount of tap water is 5400t/a, and the amount of concentrated water produced is 1350t/a. This part of the concentrated water is mainly clean sewage with high salt content, which is directly discharged into the sewage treatment plant for treatment.

General layout

Combined with the existing site conditions, the floor plan of the 125t/h compound feed mill is designed with the best aniaml feed production processes (logistics, people flow, information flow, energy flow) and production process engineering.

The overall layout emphasizes the rationality of logistics and reduces the return, crossover, and round-trip of logistics. Wait for efficient handling; reduce inventory and work-in-progress, shorten stagnation and waiting for materials; choose appropriate loading and unloading handling methods and machinery.

The overall layout follows the principles of intensive and compact land use, reasonable functional zoning, smooth process flow, and short transportation lines.

The building layout is combined with the shape of the land, fully considering the requirements for sunlight, ventilation, and fire protection, and at the same time, it is coordinated with the surrounding environment.

When laying out the general layout, strictly follow the relevant provisions of the "Code for Fire Protection Design of Buildings" .

125 t/h compound feed mill process design

01

Raw material receiving (unloading, feeding):

Incoming bulk corn and soybean meal are unloaded in the unloading shed. After being unloaded into the grain pit, they are lifted into the silo by the elevator for use. There are four 1500t corn silos and six 250t soybean meal silos.

During production, the silo is transported and lifted to the production workshop by a bucket elevator. Bags of wheat, bran and other auxiliary materials are stored in the warehouse after incoming materials.

During production, bagged wheat, bran, sub-flour, rapeseed meal, cottonseed meal and other auxiliary materials pass through independent feeding (flip-type closed air feeding port) receiving systems. After receiving the materials, they are transported to the screening process by pipelines.

Due to the nature of the work, , personnel ratio and equipment settings, and the receipt of raw and auxiliary materials is not carried out at the same time.

02

Impurity removal and crushing (sieving, magnetic separation, crushing):

During production, corn kernels and soybean meal are transported to the cylindrical primary cleaning screen and permanent magnetic screen in the production workshop respectively by a closed conveying system, and auxiliary materials such as wheat, bran, secondary flour, rapeseed meal, cotton meal, etc. are transported through scraper conveyors and elevators. Transported to cylindrical primary cleaning screen and permanent magnetic screen.

After the initial cylindrical cleaning screen and permanent magnetic screen remove impurities, it enters the crusher. The screening is mainly to remove sand, gravel, plastic and other impurities in the raw materials. The magnetic separation is mainly to remove some magnetic impurities in the raw materials and protect the safety of equipment and feed.

After screening and magnetic separation, the raw materials enter the crusher for crushing and are then lifted to the batching bin by bucket elevators to wait for batching.

03

Ingredients:

Multi-bin digital batching is used, and five closed batching bins are set up. The total capacity of the batching bins is about 750 cubic meters. The measured materials are grouped according to their physical characteristics or weighing range, and each group is equipped with a corresponding measuring device.

04

Mixing:

Continuous mixing process is used in this 125t/h compound feed mill. The continuous mixing process is to continuously measure various feed components at the same time and mix them into a stream containing various components in a certain proportion according to customer and product requirements. When the stream enters the mixer, it is continuously Mix to form a uniform stream.

The mixed finished powder can be granulated as needed, or can be directly packed into the finished product warehouse or packed into a bulk finished product warehouse and loaded on a bulk truck for shipment.

05

Granulation:

The materials mixed by the mixer enter the animal livestock poultry feed pellet machine through the feeder, add steam (the steam is provided by the natural gas boiler and transported through the steam pipeline) for high-temperature quenching and tempering (the temperature is about 60~80°C), and then go through the pressure of the animal feed pelletizer. Molding rollers squeeze out pelletized feed.

06

Cooling:

After pelleting, the pellets have a large moisture content and a high temperature. Under these conditions, the pellet feed is prone to deformation, breakage, mildew and adhesion. Use a cooler (air cooling) to cool down and air-dry the materials.

07

Crumbling:

After the granular feed is cooled, part of the feed is sent to the crusher to break the long pellets into products that meet the product specifications according to the customer's pellet size requirements.

08

Screening, inspection and packaging:

The cooled granular feed or cumbled feed is sorted through a grading screen, and the finished products are inspected. Those that pass the inspection are automatically packaged by the packaging machine, and then sent to the finished product warehouse for storage. Unqualified feed pellets are re-pelletized.

09

Inspection:

For products, inspection equipment such as near-infrared spectrometers can be used to measure conventional indicators such as protein, fat, moisture, ash, and cellulose in feed. At the same time, amino acids, fatty acids, peroxide values, acid values, and biogenic amines in feed can also be measured.
