3.1 Product Name

Hengmei Intelligent Manufacturing Programmable Quantitative Sealing Machine

3.2 Product Model

HM-FKJ

3.3 Product Overview

The HM-FKJ programmable quantitative sealing machine is an intelligent packaging equipment driven by an intelligent circuit, equipped with a dedicated internal heating roller. It is specially designed for sealing 51-well quantitative plates and 97-well quantitative plates. When used with microbial detection reagents, it provides a simple, rapid and accurate quantitative detection solution for total coliforms, fecal (thermotolerant) coliforms and Escherichia coli.

The 51-well and 97-well quantitative plates matched with the machine are designed based on the traditional Most Probable Number (MPN) statistical model, which can quantitatively detect water sample results. This method can replace and outperform traditional methods (such as membrane filtration and multiple-tube fermentation) for microbial detection in water.

As a core component of the enzyme substrate method detection device, the HM-FKJ sealing machine, together with 51-well/97-well quantitative detection plates, 100mL quantitative bottles and enzyme substrate method detection reagents, forms a complete detection system. It is applicable to the detection of various water samples, including drinking water, source water, bottled water, reclaimed water, secondary water supply, pipeline water, wastewater, food processing water, livestock water and medical water.

The machine adopts the enzyme substrate method, which is a standard method included in GB 5750-2006 for E. coli detection and is currently the most advanced method for E. coli detection in water. Compared with traditional detection methods, it has the advantages of fewer operation steps, lower requirements on the experimental environment, shorter detection time (only 24 hours), and low false positive rate, making it widely applicable to daily water sample monitoring and emergency monitoring.

4. Core Technologies and Functional Features

4.1 Core Technologies

• Intelligent Circuit Control Technology: The machine is driven by an intelligent circuit, which can accurately control the operation of the heating roller, sealing pressure and sealing time. It ensures the stability and consistency of the sealing effect, avoiding problems such as liquid leakage and hole breakage, and the reliability of the sealing process meets the standard of "no liquid leakage, no hole breakage".

• Optimized Heating Roller and Temperature Control Algorithm: The dedicated internal heating roller has an optimized layout of heating elements. Combined with a high-precision temperature control algorithm, it can quickly reach the set temperature (preheating time ≤ 3 minutes) and maintain a stable temperature during the sealing process. This not only improves the sealing efficiency (sealing speed of 10 seconds per plate, sealing time for 51-well/97-well plates ≤ 12 seconds per piece) but also reduces energy consumption, achieving the effect of high efficiency and energy saving.

• Human-Machine Interaction Interface Technology: The machine is equipped with an intuitive and easy-to-understand touch screen interface and a large LCD display window. It supports clear display of working parameters (such as sealing time, temperature) and equipment status, and allows users to easily set and adjust parameters. At the same time, it is equipped with a backspace key for parameter correction, facilitating user operation.

• Fault Self-Diagnosis and Protection Technology: The machine has a built-in fault self-diagnosis system, which can automatically detect abnormal conditions (such as overload, short circuit) during operation and issue error prompts through the display window. It is also equipped with multiple safety protection measures, including overload protection and short circuit protection, to prevent equipment damage and ensure the safety of operators.

• MPN Statistical Model Matching Technology: The sealing machine is precisely matched with 51-well and 97-well quantitative plates designed based on the MPN statistical model. The sealing process ensures the integrity of the well structure and the tightness of the plate, avoiding external contamination of the sample during the culture process, and ensuring the accuracy of the MPN quantitative calculation results of the final water sample.

4.2 Functional Features

• High Efficiency and Energy Saving: The optimized layout of heating elements and temperature control algorithm not only shorten the preheating time (≤ 3 minutes) and improve the sealing speed (10 seconds per plate, sealing time for 51-well/97-well plates ≤ 12 seconds per piece) but also reduce energy consumption, adapting to the needs of high-frequency continuous operation in large-scale detection scenarios.

• Simple Operation: The touch screen interface and large LCD display window make parameter setting and status monitoring intuitive and easy. Users can master the operation after simple training. The machine is also equipped with a backspace key for parameter adjustment, a quantitative plate counting function (convenient for counting the number of sealed plates), an automatic energy-saving function (reducing energy consumption when idle), and a one-key drainage function (facilitating daily maintenance), further simplifying the operation process.

• Safety and Reliability: It has multiple safety protection measures, including overload protection and short circuit protection, to prevent equipment failure caused by abnormal current or voltage. The outer cover temperature during operation is < 40℃, avoiding scalding risks to operators. The machine has high stability, with a service life of more than 5 years and the ability to detect more than 50,000 samples, ensuring long-term stable operation.

• Low Environmental Requirements: Unlike traditional detection methods (such as multiple-tube fermentation and membrane filtration) that require a clean laboratory, the HM-FKJ sealing machine, when used with the enzyme substrate method, has no special requirements on the experimental environment. It can be used in on-site emergency detection and field detection scenarios, improving the flexibility of application.

• Rapid Detection Support: The machine cooperates with the enzyme substrate method to shorten the detection time of total coliforms, fecal coliforms and Escherichia coli in water to 24 hours, which is much shorter than the 2-3 days of membrane filtration and 3-5 days of multiple-tube fermentation. It can quickly provide detection results, which is of great significance for emergency response to public safety incidents and real-time monitoring of water quality.

• Wide Detection Range Adaptability: It can be used with 51-well quantitative detection plates (detection range: 0-200 MPN/100mL for undiluted water samples) and 97-well quantitative detection plates (detection range: 0-2419 MPN/100mL for undiluted water samples), meeting the detection needs of different concentration levels of microorganisms in water samples.
