Product plan

The product produced by this 10-15t/h livestock and poultry feed mill plant in Uzbekistan project is livestock and poultry feed. The product plan of this project is shown in the table below.

Project composition and construction content

This 10-15t/h livestock and poultry feed mill plant in Uzbekistan project uses the newly built factory building in the factory area as the production site. The project does not involve new land use. The main construction content is the construction of the 2-6F factory building of the production workshop, the installation and commissioning of the production line and equipment.

The project volume is small and there is no civil engineering. This poultry livestock feed production line project builds a new factory building to renovate its interior and install equipment, and at the same time builds a 6-story feed production workshop. The main components of this project are shown in the table below.

Main production equipment

The main production equipment of this 10-15t/h livestock and poultry feed mill plant in Uzbekistan project is detailed in the table below.

Note: The hourly capacity of the livestock and poultry feed mill plant in Uzbekistan is 10-15 tons, the annual working days are 300 days, and the working hours are 16-24 hours a day, so the annual output of feed is 108,000 tons.

Considering the abnormal situations such as equipment maintenance and normal overhaul, its capacity is less than the expected capacity, which is basically matched with the designed annual production of 100,000 tons of feed, and can meet the production needs of products.

Main raw and auxiliary materials

The annual consumption of main raw and auxiliary materials and energy used in this 10-15t/h livestock and poultry feed mill plant in Uzbekistan project is shown in the table below.

Material balance analysis

The material balance of this 10-15t/h livestock and poultry feed mill plant in Uzbekistan project is shown in the table below.

Animal feed production Process design of this project

Based on the customer's raw materials and feed types, the feed production process we designed for the customer is mainly divided into raw material unloading, transportation, impurity removal, crushing, batching, mixing, granulation, and packaging sections.

The raw material receiving and storage section combines manual and mechanical receiving methods.

After the packaged raw materials are transported to the factory by car, they are unloaded manually and transported to the raw material warehouse by forklift for partitioned stacking; corn, soybean meal, wheat bran, flour, puffed soybeans, rice bran, and additives are transported to the factory by car in bagged form and unloaded directly to the raw material warehouse; soybean oil is received by tank trucks and then pumped to oil storage tanks for storage.

Since the dust-producing raw materials used in this 10-15t/h livestock and poultry feed mill plant in Uzbekistan project are all in bagged form, the amount of dust generated in the unloading and storage links is not considered.

Raw material transportation and impurity removal:

Impurities in feed raw materials not only affect the quality of feed products but also directly affect feed processing equipment and personal safety. In severe cases, the entire equipment may be damaged, affecting the smooth progress of feed production.

Therefore, before the raw materials are crushed, the raw materials (mainly corn, soybean meal, wheat bran, flour, puffed soybeans, rice bran) need to be cleaned of coarse impurities and metal impurities inside the raw materials through fences, primary cleaning screens, and permanent magnetic drums.

The raw materials are lifted to the sixth-floor primary cleaning section by the production workshop elevator. The raw materials entering the material pit are cleaned of larger impurities by the fence at the feed inlet, and then transported by scraper conveyors and self-cleaning elevators through primary cleaning screens and permanent magnetic drums to remove coarse impurities and metal impurities inside the raw materials.

The raw materials entering the screen drum, the raw materials passing through the screen holes, enter the permanent magnetic drum through the material pipe, and then enter the silo through the distributor. The debris or agglomerated raw materials that do not pass through the screen holes are separated into the waste pipe and taken out by workers for separate treatment.

Crushing:

The qualified raw materials are fed according to the production plan and then sent to the crushing bin by the elevator. The granular raw materials that need to be crushed in this project include corn, wheat bran, soybean meal, etc.

The material to be crushed enters the crushing bin after initial cleaning, is fed through the top feed port of the feeder, and enters the crushing chamber of the crusher to the left or right through the feed guide plate.

Under the impact of the high-speed rotating hammer and the friction of the screen plate, the material is gradually crushed and discharged from the base outlet through the sieve holes under the action of centrifugal force and airflow. The raw material is crushed and the outlet temperature is generally 7-12°C. The fineness of the raw material can be controlled by the size of the screen (about 1.5mm-2mm).

The 10-15t/h livestock and poultry feed mill plant in Uzbekistan project uses a high-frequency speed-regulating crusher, which has the characteristics of good sealing, good stability and low noise.

PLC automatic batching:

A scraper conveyor is set under the crusher. The crushed raw materials are transported to the collecting hopper by the scraper conveyor, and then sent to the batching bin by the self-cleaning elevator and distributor; the first batching section of the project has a total of 22 batching bins with a total volume of 300m3.

Various raw materials are input into the computer according to the formula, and the computer automatically weighs and batches according to the program.

The raw materials in the batching bin are automatically batched, and the central control system monitors the weighing sensor signals, etc., and the materials are batched into the double-shaft paddle mixer through the batching scale bucket; the small materials are added separately after being mixed, and are added manually. The project is equipped with a small material calibration scale.

Mixing:

The batched materials are automatically put into the mixer and mixed for 3 minutes.

Conditioning:

Steam is used for conditioning. Conditioning is the most important link in the granulation process. The quality of the granular feed is directly determined by the quality of the granular feed. The purpose of conditioning is to condition the prepared dry powder into a powdered feed with a certain amount of moisture and humidity that is conducive to granulation, mature the material, improve the suitability, increase the digestibility, and inactivate miscellaneous bacteria. The conditioning temperature is 75-90℃ and the time is 180 seconds.

The prepared powder enters the conditioner cylinder through the automatic feeder, and the powder is thrown up and pushed by the rotating conditioner blades to continuously mix with the high-pressure steam sprayed into the conditioner cylinder, causing the starch in the powder to gelatinize and the protein to denature. The high-temperature steam can also play a sterilizing role.

Granulation:

The powder is directly lifted into the powder bin without crushing, and the mixed material is lifted into the granulation bin, granulated by the livestock poultry feed pellet machine, and the prepared pellet feed is cooled to room temperature by the wind cooler.

The cooled feed is graded, measured, packaged, and put into storage. Feed products that do not need to be packaged are transported to the product storage area for temporary storage or directly transported by downstream merchants. Since the finished feed pellets of this livestock and poultry feed mill plant in Uzbekistan project are relatively large, bulk pellet transportation and storage dust are not considered.

After production, the finished product needs to be tested. The test items include moisture, crude protein, crude ash, calcium, total phosphorus, arsenic, lead, aflatoxin, etc. The reagents used are sulfuric acid, hydrochloric acid, sodium hydroxide, ethanol, etc.
