Study on the influence of feed grinder on feed quality and quality control method

The feed grinder plays a crucial role in the feed processing by directly impacting feed quality. Below is a study on the influence of feed grinders on feed quality and corresponding quality control methods:

Particle Size Control

The feed grinder can crush feed materials into desired particle sizes, which significantly affects digestibility, absorption, and feed uniformity. Controlling particle size involves adjusting parameters such as blade clearance and screen aperture. Quality control methods include regular inspection and calibration of equipment to ensure blade wear meets specifications, and using appropriate screen apertures.

Control of Feed Quality Loss

During feed grinding, friction and heat generation can lead to nutrient and active substance losses. Measures to minimize quality loss include controlling grinder speed and temperature to prevent excessive friction and heat accumulation, selecting appropriate blade materials and designs to reduce thermal and mechanical damage to the feed, and optimizing grinding processes to reduce repeated grinding cycles.

Uniformity of Feed Composition Control

The operational effectiveness of the feed grinder directly influences the uniformity of various components in the feed. Uneven grinding can affect the nutritional balance of the feed and the growth performance of animals. Quality control methods include:

Regular inspection and calibration of equipment to ensure uniform wear of blades and proper condition of screens.

Selecting appropriate grinding process parameters, including feed rate and screen aperture, to ensure uniform feed grinding.

Equipping suitable mixing equipment to thoroughly blend ground feed with other components and enhance feed uniformity.

Feed Safety Control

Quality control of feed grinders also includes ensuring the safety of feed. Feed may contain microorganisms, harmful substances, etc., which can be detrimental to animal health. Quality control methods include:

Regular cleaning and disinfection of grinders to prevent the growth of bacteria, mold, etc.

Adopting appropriate feed processing techniques such as drying, cooking, etc., to eliminate microorganisms and remove harmful substances.

Strict adherence to feed safety standards and regulations to ensure compliance with relevant legal requirements.

In conclusion, the feed grinder plays a crucial role in feed quality control. Effectively controlling particle size, minimizing quality loss, ensuring feed composition uniformity, and guaranteeing feed safety enhance feed quality. This improvement boosts nutritional value, digestibility, and productivity of livestock and poultry.
