6. Application Scenarios and Industry Adaptation

6.1 Common Application Scenarios for Both Models

• On-site Testing: Both models are portable (equipped with trolley cases with good shock resistance and waterproof performance), and suitable for on-site testing scenarios such as grain purchasing sites, feed raw material receiving sites, and food processing raw material inspection sites. The simple sample pretreatment and short detection time (12 minutes for the entire process) enable rapid on-site detection and timely feedback of results.

• Laboratory Testing: They can be used in the laboratories of enterprises and testing institutions for daily detection work. The large storage capacity, data transmission, and printing functions facilitate the management and archiving of detection data, and meet the needs of laboratory standardized testing.

6.2 Industry Adaptation

• Grain Industry: Suitable for local grain depots, grain production enterprises, etc. It can detect fungal toxins in grain (rice, corn, wheat, barley, sorghum, etc.) to ensure the quality and safety of grain storage and processing.

• Feed Industry: Applicable to feed factories and various animal husbandry and breeding enterprises. It can detect fungal toxins in feed and its raw materials, preventing the impact of feed contaminated by fungal toxins on the health of breeding animals and ensuring the safety of animal products.

• Food Processing Industry: Suitable for flour mills, food processing plants, etc. It can detect fungal toxins in raw materials (such as flour, edible oils, milk, etc.) used in food processing, ensuring the safety of food products.

• Testing and Supervision Industry: Applicable to third-party testing institutions and government supervision departments at all levels. It can provide rapid and accurate detection data for food safety testing and supervision work, improving the efficiency of testing and supervision.

6.3 Model-specific Adaptation Advantages

• HM-LZ1 Adaptation Advantages: The 10.1-inch large touch screen makes the operation and display more intuitive, which is more suitable for scenarios where multiple operators need to view and operate the instrument at the same time. The single-channel design is more cost-effective for small-scale detection needs (such as small feed factories with low daily detection volume).

• HM-LZ2 Adaptation Advantages: The 6 independent detection channels can simultaneously detect multiple samples or multiple projects, which is more suitable for scenarios with large detection volume and high detection efficiency requirements (such as large grain depots, third-party testing institutions with heavy testing tasks). The 7-inch touch screen is compact and easy to carry, and the integrated incubation and detection design further improves the detection efficiency.
