02

Crushing section

The materials to be crushed (corn, soybean meal) are fed from the top feed port through the feeder matched with this machine, and enter the crushing chamber from the left or right through the feed guide plate. They are struck by the high-speed rotating hammer and rubbed by the sieve plate.

Under the action, the materials are gradually crushed, and are discharged from the base outlet through the screen holes under the action of centrifugal force and air flow.

03

Ingredients and mixing

Batching: After automatic PLC measurement, various materials are transported through the auger into the batching scale in proportion to ensure that the material weight tolerance is within the range allowed by the feed company.

Mixing: After automatic batching, the materials enter the mixing system to fully mix various materials with a mixing uniformity of over 93%. This section is a key to ensure feed quality.

This section of 3*25 t/h animal feed mill in Vietnam uses a high-efficiency double-shaft paddle mixer, and multiple liquid addition devices can be set up according to the needs of the formula. During the mixing process, the flow rate and optimal time of liquid addition are controlled by a microcomputer to ensure that the liquid raw materials and solid phase raw materials are fully mixed evenly.

In order to reduce cross-contamination of feed raw materials and improve the working environment, a pulse bag dust filter is installed on the hand feeding device to return the dust of the added raw materials to the original process line. The mixed ultra-fine powdered feed enters the subsequent expansion and granulation process.

The Vietnam Compound Feed Market size is expected to grow from USD 11.54 billion in 2023 to USD 15.30 billion by 2028, at a CAGR of 5.80% during the forecast period (2023-2028).

Growing livestock share in agricultural output and accelerating disposable income of consumers are the significant factors driving the compound feed market in the country.

The increasing demand for meat and meat-based products is among the prime factors driving the demand for compound feed in the country.

The demand for higher-quality meat at lower prices has been witnessing an upward trend in Vietnam. Economic growth has boosted the consumers' purchasing power, most of which is directed to the consumption of livestock meat. For instance, per capita, meat consumption has increased from 49.9 kg in 2020 to 51.3 kg in 2021. The increase in meat consumption increases the demand for compound feed, contributing to market growth.

Along with this, the Vietnamese, agencies, and ministries have introduced several schemes in the past, such as the livestock development strategy, to augment the government livestock sector, which resulted in an increment in production and meat consumption.

According to Law on Animal Husbandry, there is a need to apply science and technology in livestock production to improve the productivity, quality, efficiency, and competitiveness of the animal husbandry sector, to ensure food safety, epidemic safety, environmental protection, and to cope with climate changes.

Moreover, Vietnam's import demand for corn and grain by-products for animal feed has been growing. Corn account for the majority, while the rest will be wheat and barley, reflecting the trends of the meat industry. Therefore, the favorable government policies for animal husbandry and the demand for meat strengthen the compound feed market in the country during the forecast period.
