Brief description of grass cattle pellet feed making process flow

1. Receiving raw materials
   After weighing with a truck, the raw materials are unloaded to the unloading pit using a hydraulic flap, and the canned raw materials are transported into the warehouse by a forklift.
2. Storage of raw materials
   There are two types of silos in grass feed mills: silos and room-type silos. The main raw materials, such as corn and other cereal raw materials, have good fluidity and are not easy to agglomerate.
   They are mostly stored in silos, while auxiliary materials, such as bran, soybean meal and other powdered raw materials, have poor scattering properties. After being stored for a period of time, they are easy to agglomerate and difficult to discharge. They are stored in room-type silos.
3. Feeding and transportation of raw materials
   Powdered feed auxiliary materials such as bran, soybean meal and other raw materials are manually fed at the feeding port of the raw material warehouse, and the raw materials are transported by bucket elevators.
4. Screening and impurity removal
   Impurities in feed raw materials not only affect the quality of feed products but also directly affect the feed processing equipment and personal safety. In severe cases, the entire equipment may be damaged, affecting the smooth progress of feed production, so they should be removed in time.
   Feed cleaning equipment is mainly screening equipment, which removes large and long debris such as stones, mud, and sack pieces from the raw materials.
5. Crushing of raw materials
   This 20-25t/h cattle feed grass alfalfa pellet production line in UK project adopts a secondary crushing process, equipped with two hammer-type crushers. By adjusting the gap between the hammer and the screen, coarse crushing and fine crushing are achieved. After crushing, it enters the batching bin to wait for batching.
6. Batching process
   This process flow includes batching with one bin and one scale, batching with multiple bins and several scales, and batching with multiple bins and one scale. The measured materials are grouped according to the weighing range, and each group is equipped with a corresponding metering device.
7. Mixing process
   Batch mixing process is adopted to mix various mixed components according to the proportion of the formula, and send them to the periodically working "batch mixer" for batch mixing. This mixing method is more convenient to change the formula, and there is less mixing between each batch. It is a commonly used mixing process at present.
   The opening and closing operations are relatively frequent, so most of them adopt automatic program control. The mixing process adds feed additives according to product requirements and mixes them in a double-shaft paddle high-efficiency mixer, then sends them to the pelleting section via a scraper conveyor.
   The double-shaft paddle high-efficiency mixer in this process is a fully enclosed machine, and feed additives and other small materials are manually added at the small material addition port in the workshop.
8. Tempering and granulation
   It aims to improve the maturity of feed, improve the digestibility and utilization of nutrients, and kill some harmful substances. Tempering is the most important link in the pelleting process. The quality of tempering directly determines the quality of pellet feed.
   The purpose of tempering is to temper the prepared mixture into a powdered feed with a certain amount of moisture and humidity that is conducive to pelleting. The moisture content of the mixture is 10%.
   At present, cattle feed grass feed production line complete the tempering process and replenish moisture by adding steam. Generally, 60kg of saturated steam (containing 6% moisture) is required for each ton of feed tempering. Granulation ensures that the fully tempered raw materials are pressed into pellets suitable for animal consumption, thereby improving breeding efficiency.
9. Cooling and screening
   During the pelleting process, high-temperature and high-humidity steam is introduced and the material is squeezed to generate a large amount of heat, so that the moisture content of the pellet feed is as high as 16% and the temperature is as high as 75℃-85℃ when it just comes out of the cattle feed grass pellet machine.
   Under such conditions, the pellet feed is easy to deform and break, and it will also cause sticking and mildew during storage. The moisture content must be reduced to below 12% and the temperature must be reduced to below 8℃ higher than the air temperature.
   It is necessary to use a countercurrent pellet cooler combined with a fan for cooling. No heating is required during the cooling process. Natural wind is used throughout the process, and 4% of the moisture is carried out by wind.
10. Screening
    After the pellet feed is processed by the crushing process, a part of the powder clots and other materials that do not meet the requirements will be produced.
    Therefore, the crushed pellet feed needs to be screened into products with neat particles and uniform size. The screening equipment of this 20-25t/h cattle feed grass alfalfa pellet production line in UK project is equipped with a rotary vibrating grading screen.
11. Packaging process
    The grass feed pellets are sent to the packaging system to fill the products into woven bags, packaging bag conveyors and fixed packaging units.

What are the prospects for cattle and sheep grass feed pellet processing in the UK?

The British cattle and sheep feed processing industry developed steadily in the first half of the 1980s, with grassland and pasture occupying a dominant position in feed production.

The economic income of grassland is about three times the output value of horticultural products, showing its important position in the national economy. The prospect of grass pellet feed processing in the UK is very broad and has significant development potential.

Market demand and economic benefits

The market demand for grass pellet feed is large, especially in winter, when natural forage is reduced and its nutritional value is reduced, the demand for grass pellet feed is more urgent. Processing grass pellet feed can significantly improve the feed conversion rate and obtain more meat, eggs, and milk with less forage grass, thereby reducing breeding costs and improving economic benefits.

In addition, grass pellet feed processing can also drive the development of related industries, such as the production and sales of feed pellet mills, further promoting economic growth.

Technical requirements and equipment needs

The key technology for processing grass pellet feed is to adjust the moisture content of the raw materials. The optimal moisture content range is 14%-16% for leguminous forage and 13%-15% for grassy grass. A pellet feed mill is used during the processing. The grass meal is stirred and squeezed during the pelletizing process.

The temperature of the pellets coming out of the sieve reaches about 80°C. After cooling, the moisture content generally does not exceed 11%-13%, which is suitable for long-term use. Storage without moldy deterioration‌.

Policy support and environmental benefits

The government's emphasis on environmental protection and resource reuse also provides policy support for grass pellet feed processing. Processing waste straw and other resources into feed not only turns waste into treasure, but also reduces environmental pollution, which is in line with the concept of sustainable development‌.

In addition, grass pellet feed is small in size, has less dust, is easy to store and transport, and is beneficial to the health of humans and animals.

In summary, grass pellet feed processing not only has huge market demand and significant economic benefits, but also has the advantages of environmental protection and sustainable development, and has a very broad prospect.

Driven by market demand and trade agreements, the British cattle and sheep feed processing industry has broad development prospects. As environmental protection and health standards improve, the industry will pay more attention to eco-friendly production methods to adapt to the needs of the international market.
