How to make professional animal feed

In the field of animal husbandry, homemade feed can not only effectively control costs, but also accurately adjust nutrition according to the growth stage of animals. This article will systematically explain the whole process from raw material selection to pellet forming, especially for the selection and operation points of feed pellet machine.

Scientific ratio of raw materials

The basis of high-quality Animal feed lies in the ratio of raw materials. It is recommended to use corn (45%), soybean meal (22%), and wheat bran (18%) as the main ingredients, with 5% fish meal and 10% premix. Different livestock species need to adjust the formula parameters: poultry needs to increase the calcium-phosphorus ratio, and ruminants should add fiber. When processing through the feed pellet machine, it is recommended to control the moisture content of the raw materials in the range of 12-15% to ensure the forming rate.

Core Processing Process

Raw material pretreatment:

crush to 2-3mm particle size, sieve to remove impurities

Mixing and stirring:

use a double-shaft paddle mixer, coefficient of variation ≤5%

Tempering and maturation:

pass 90℃ steam for 30 seconds, starch gelatinization degree reaches 85%

Pellet forming:

selection of die hole diameter of feed pellet machine (poultry feed 3-5mm/pig feed 4-8mm)

Cooling and drying:

countercurrent cooler to reduce the particle temperature to room temperature ±5℃

Key parameters of feed pellet machine

When choosing a feed pellet machine, focus on:

Die roller gap (0.1-0.3m m)

Spindle speed (250-350rpm)

Capacity matching (home use 50kg/h, industrial grade 1t/h or more)

Power configuration (7.5kW motor can meet the needs of small and medium-sized farms)

Key points of quality control

Finished feed should meet the following requirements:

Pellet hardness ≥8kg/cm² (tested with a hardness tester)

Powder content <1% (determined by vibration screening)

Water stability >2 hours (fresh water immersion test)

It is recommended to calibrate the roller pressure of the feed pellet machine every month and replace the worn ring die in time, which can extend the life of the equipment by more than 30%. Manufacturers usually equip modern feed pellet machines with PLC control systems, enabling automatic adjustment of temperature and feed amount.

By combining scientific formulas with professional equipment, homemade Animal feed can reduce breeding costs by 18-25%. The rational use of feed pellet machines can not only improve feed conversion rate, but also effectively inactivate pathogenic microorganisms during the high-temperature pelleting process. Experts recommend that farmers choose suitable models based on actual production capacity requirements and establish a complete quality traceability system.
