How can we optimize the analysis of core nutritional parameters for each batch of agricultural products entering storage at lightning speed? This is always a practical challenge for animal feed production managers.

The operation of physico-chemical testing laboratories always faces the pressure of maintaining a narrow error range. We need standardized hardware tools to ensure data consistency.

This article provides a list of specialized equipment to help your testing laboratory perfectly meet the TCVN 1525 2001 standard. The synchronization of physico-chemical technology will improve inventory efficiency and optimize costs.

1. Vietnamese National Standards (TCVN) on Animal Feed Testing

1.1 Soxhlet Extraction Principle for Quantitative Crude Fat Determination

Gravimetric analysis plays a crucial role in assessing the quality of raw materials. National Standard TCVN 1525 2001 specifies the technical procedure for determining the crude fat content in animal feed. This standard for substrate separation is entirely equivalent to the international standard ISO 6492:1999.

The extraction process requires the use of diethyl ether or petroleum ether solvents with a boiling temperature range of 40°C to 60°C. The organic solvent will dissolve and separate free lipids from the coarse structure of the sample. Adherence to this temperature range prevents the denaturation of the carbon structure of the fat.

1.2 The Importance of Internal Sample Control Data

Physicochemical analysis data records are the scientific basis for pricing input agricultural products. A quality control system helps you establish allowable error limits between parallel measurement batches. This ensures consistency in the formula of the aquaculture feed production plant.
On the other hand, these data serve as objective evidence for quality inspections. Maintaining data integrity enhances the brand’s competitive position in the market. This is a strategic step for the lab to achieve ISO 17025 competency certification.

2. Near-Infrared (NIR) Technology for Grain Analysis

2.1 Mechanism of Near-Infrared Spectral Light Absorption

Near-Infrared (NIR) spectroscopy technology provides a non-destructive quantitative solution for sample analysis. When light passes through the grain, characteristic chemical bonds such as C-H, O-H, and N-H absorb energy at selective wavelengths. The analyzer applies optical algorithms to extract and analyze these absorption spectral bands.
The system automatically converts the signal pulse into percentage content of crude protein, crude fat, crude fiber, and moisture. The entire analysis cycle takes place entirely in its raw state without the need for chemical wetting. Therefore, this dynamic method completely eliminates the risk of human error.

2.2 The Granolyser’s High-Speed ​​Multi-Parameter Measurement Capability

To optimize the raw material acceptance process, we need a synchronized wide-range hardware solution.
