Main feed production Process design

The main process of this 4t/h livestock and fish feed processing line in Netherlands project includes raw material receiving and cleaning section, crushing section, batching and mixing section, granulation section, and finished product packaging section. The following is a detailed introduction to the process design of this production line:

1. Raw material receiving and cleaning section

The main materials (excluding edible oil) and premix purchased for this fish and livestock feed production line project are all packaging raw materials, transported by car and stacked in the raw material room.

After the raw materials are purchased, they must be inspected and qualified before they can be used. After the raw materials arrive at the factory, the purchasing staff will notify the quality control staff. The quality control staff will sample the raw materials according to regulations and first conduct an appearance inspection on the raw materials.

If there is mildew and insect damage and it exceeds the company's acceptance standards, it should be returned. The raw materials that have passed the appearance inspection will be sent to the laboratory for inspection and operation according to regulations.

If the inspection results meet the specified standards, the purchase is agreed. The quantity of bagged raw materials should be counted after unloading.

For raw materials that have passed the inspection, impurities are removed by primary screening and permanent magnetic drums when they are used.

The purpose of raw material cleaning is to remove impurities in the raw materials. Impurities not only affect the growth of animals, but also easily cause pipelines and equipment to be blocked, and even damage equipment (screens, ring molds, etc.).

This 4t/h livestock and fish feed processing line in Netherlands project uses primary cleaning screens and permanent magnetic drums for raw material cleaning.

The main equipment for raw material cleaning includes feeding hoppers and fences, scrapers, self-cleaning elevators, primary cleaning screens, permanent magnetic drums, rotary distributors, etc.

The raw materials of this project are fed manually. Workers unpack the bagged raw materials and pour them into the feeding port. A fence is set at the feeding port to prevent large pieces of material from entering and damaging the equipment. After the raw materials enter the feeding hopper, they are scraped into the elevator by the scraper, lifted to a certain height, and then enter the primary cleaning screen and permanent magnetic drum in turn to remove large particles and magnetic impurities such as screws.

This 4t/h livestock and fish feed processing line in Netherlands project has two manual feeding ports. The granular materials in the raw materials need to go through the crushing section, and the powder materials do not need to go through the crushing section.

Feed port I only feeds raw materials that do not need to be crushed, etc., and directly feeds them into the mixing and batching section after feeding. Raw materials fed into feed port II are sent to the silo to be crushed after impurities are removed through a distributor.

2. Crushing section

The raw materials that have passed the inspection and have been initially cleaned enter the crusher from the silo to be crushed through the buffer bucket.

According to the design plan, this project is equipped with a crusher, which is interconnected with the silo to be crushed through a pneumatic tee and a pneumatic gate. The aperture of the crusher screen plate needs to be adjusted for different raw materials.

The feed amount should be adjusted in time during the crushing process. When replacing the sieve plate daily, the wear of the hammer should be checked and the hammer should be replaced or adjusted in time. During crushing, the direction of the crushed material should be confirmed to confirm whether it has reached the designated batching bin to avoid cross-bin.

This 4t/h livestock and fish feed processing line in Netherlands project is equipped with a feed crusher, a pulse bag dust collector, and a muffler at the air outlet.

After crushing, the raw materials are sent to the batching bin of the batching and mixing section.

3. Batching and mixing section

Batching is the process of feeding and measuring various types of feed raw materials according to the formula requirements using a specific batching device. Batching technology is a key link in the feed production process.

Before batching, the batcher should verify the formula and adjust the size of the material column according to the thickness of the spiral to reduce the batching error. In the batching process, different parameter coefficients should be set according to the characteristics of each raw material to ensure the accuracy of the batching. This animal feed production line project uses an electronic batching scale, which has the characteristics of fast weighing speed, high batching accuracy, and stable performance.

The batching sequence refers to the following principles: according to the coarseness of the material particle size, the coarse particles should be batched first and the fine particles should be batched later; according to the specific gravity of the material, the small specific gravity should be batched first and the reverse should be batched later; according to the amount, the large amount should be batched first and the reverse should be batched later.

The uniform mixing of feed raw materials is the prerequisite for the uniform distribution of nutrients in the feed. Feeding animals with unevenly mixed feed will cause animal nutritional deficiencies on the one hand, and on the other hand, it will cause animals to eat excessive amounts of drugs and even cause poisoning.

The premix of this 4t/h livestock and fish feed processing line in Netherlands project is fed manually. Workers unpack the bagged raw materials and pour them into the feeding port. Edible oil is sprayed in through a nozzle through a pipe to facilitate uniform mixing.

Put the prepared raw materials into the mixer, add premix and edible oil according to the process requirements. The mixing efficiency and uniformity of the mixer determine the quality of the finished product.

After the best mixing uniformity is achieved, the mixture is put into the buffer bucket and enters the next process. Mixing is a process in which the various material components are stirred and mixed after the feed products are metered and formulated, so that they are blended and evenly distributed.

4. Granulation Section

This 4t/h livestock and fish feed processing line in Netherlands project uses steam granulation (ring die granulation) for granulation only.

Steam granulation is to subject the mixed raw materials to high-temperature steam conditioning and animal feed granulator extrusion, and then to cooling and screening to obtain finished granules.

Conditioning is to heat and wet the feed to gelatinize the starch and soften the material so that the animal feed pellet mill can improve the quality and efficiency of granulation, improve the palatability and stability of the feed, and improve the digestibility and absorption rate of the feed. After the material is processed by the finished product inspection screen, it enters the granulation bin.

According to the process requirements, the specified environment is selected and the steam pressure and temperature are adjusted. The modulation temperature is not less than 75°C and the steam pressure is not less than 0.4Mpa. The raw materials for steam granulation need to be screened by the finished product inspection screen to remove impurities to avoid damaging the ring die. The main process is as follows: conditioning-granulation-cooling.

Cooling adopts high-volume countercurrent cooling, separated by a cyclone dust collector, and equipped with a wind shutoff.

5. Finished product packaging section

After granulation, the granular materials need to be graded by a vibrating screen. According to the different particle size classification, they are divided into three layers.

The large particles on the top layer need to be crushed for the second time, the middle layer enters the finished product warehouse, and the bottom layer returns to the granulation warehouse for re-granulation.

The materials in the finished product warehouse are automatically weighed and packaged, and put into storage. The packaging line is equipped with a pulse bag dust collector.

General layout

This 4t/h livestock and fish feed processing line in Netherlands project can be divided into three major blocks according to the functional layout of the buildings: the office area is an independent building with one floor, located in the north gate area of the seed farm; the production workshop is located about 100m south of the factory gate, a building on the east side of the factory road, with a frame-type multi-story structure, divided into three parts: boiler room, finished product area and processing area.

The finished product area is located in the south of the workshop, the boiler room is located in the east of the workshop, and the processing area is located in the north of the workshop; the raw material area of this project is a separate workshop, located in the east of the factory road and north of the production workshop, mainly used for raw material warehouses.

The factory road of this project is north-south oriented. The processing room adopts reinforced concrete structure with 4 floors and a height of 20.5m. The process adopts crushing first and then batching, batching by computer, intermittent mixing process, and all production is controlled by computer. The materials are produced by self-flowing from top to bottom to reduce lifting.

How to build an animal livestock and fish feed processing line in Netherlands?

‌Building a livestock and fish feed processing line in Netherlands requires the following steps:

1. ‌Determine the production scale and demand:
   First, it is necessary to determine the processing scale of the feed factory, which is usually based on the capacity of the batching and mixing system.
   For example, the single-shift output can be calculated by the mixing amount per batch, the number of batches, the working time and the number of days.
   For example, if the mixing amount per batch is 1 ton, 10 batches are mixed per day, and the working days are 250 days, the annual output is 20,000 tons.
2. ‌Choose the right equipment:
   Choose a brand of equipment with guaranteed and stable quality, and choose the right specifications and models according to actual needs. The selection of equipment should take into account its production efficiency, energy consumption and maintenance cost.
3. ‌Rational layout of equipment‌:
   Equipment layout should avoid material backlog and cross contamination, ensure smooth cooperation between equipment, and facilitate maintenance and upkeep‌.
4. ‌Optimize production process‌:
   The production process should be scientific and reasonable to ensure smooth connection and coordination between each link, reduce energy consumption and material waste‌.
5. ‌Introduce intelligent technology‌:
   Use advanced intelligent technology to realize automatic control and data collection of equipment, improve production efficiency and product quality, and reduce production costs‌.
6. ‌Consider environmental protection and safety‌:
   When planning the plant area, factors such as logistics distance, safety regulations, and prevention of mutual interference need to be considered.
   At the same time, the overall layout of the feed mill should vary according to the changes in production nature, scale and process flow, and the building should usually account for 30-35% of the total area of the plant‌.

Through the above steps, an efficient, intelligent and environmentally friendly livestock and fish feed processing line in Netherlands can be established to meet the needs of modern animal husbandry.
