High Pressure Processing (HPP) technology, a revolutionary breakthrough in non-thermal sterilization, is propelling the food industry into a new era of safety and quality with its core equipment, the 612L ultra-high pressure HPP sterilization equipment. This technology destroys the cell structure of microorganisms under ultra-high pressure (600 MPa), achieving highly efficient sterilization at room temperature while maximizing the preservation of nutrients and flavor compounds. It has become the preferred solution for the production of liquid foods, ready-to-eat meats, and high-end health products.

I. Technical Principles and Structural Innovation

The 612L sterilization equipment employs the isostatic pressure principle. A high-pressure pump compresses the pressure-transmitting medium (usually water) to the target pressure, uniformly applying it to the packaged product. The core of the equipment consists of a triple structure: 1. Pressure vessel: Utilizing a high-strength stainless steel multi-layer winding design and equipped with a self-tightening sealing system, it can withstand over 10,000 pressure cycles; 2. Intelligent control system: Integrating PLC and HMI human-machine interface, it achieves multi-parameter coordinated control of pressure, temperature, and time, with an error range of ±0.5%; 3. Safety protection module: Includes rupture discs, mechanical interlocks, and real-time audible and visual alarm devices, meeting ASME PED certification standards.

Laboratory data shows that after processing at 600MPa pressure for 3 minutes, the kill rate of pathogenic bacteria such as E. coli O157:H7 and Salmonella reaches 6log, and the vitamin C retention rate exceeds 95%, far exceeding the effect of traditional pasteurization (Food Engineering 2025).

II. Industry Application Scenarios Analysis

1. Cold-pressed juice sector: After processing a certain brand of NFC orange juice with the 612L equipment, the shelf life was extended to 120 days, the sensory scores for color and flavor improved by 32%, and the product premium increased by 40%. The key lies in the high-pressure environment that inactivates pectin esterase, delaying precipitation and stratification (see Figure 1).

2. Sterilization of Pre-cooked Foods: For ready-to-eat protein products such as chicken breast, the equipment induces myofibrillar protein dissociation through pressure, increasing product tenderness by 25%, and ensuring microbiological indicators meet FDA 21 CFR 114 standards. Actual testing at the 2025 Asian Food Exhibition showed that Listeria monocytogenes was not detected in the treated product.

3. Sterilization of Pharmaceutical Culture Media: In the biopharmaceutical field, the equipment can achieve terminal sterilization of culture media, avoiding component denaturation caused by gamma rays or ethylene oxide. A case study from a vaccine company shows that the potency retention rate of tetanus toxoid culture media after sterilization reached 99.8%.

III. Economic Benefits and Sustainable Development

Compared to traditional high-temperature sterilization lines, the 612L equipment has significant advantages: Energy Consumption Ratio: Power consumption per unit capacity reduced by 57% (Data source: China Food Machinery Equipment Network 2026 Annual Report) Carbon Emissions: 83 kg CO₂ equivalent reduced per ton of product Overall Cost: Based on an annual production scale of 5000 tons, the investment payback period is only 2.3 years.

However, it should be noted that the equipment has special requirements for packaging materials, requiring the use of high-strength PET/EVOH composite film, which increases packaging costs by approximately 0.12 yuan per piece.

IV. Technological Boundaries and Future

Evolution Currently, the equipment faces two major challenges:

1. Spore-killing requires a combination of pressure and temperature synergy (e.g., 800 MPa + 60℃);

2. Pressure decay occurs when processing high-solids products.

The industry is exploring pulsed pressurization technology (PHPP) and ultrasonic-assisted solutions. A laboratory in the Netherlands has achieved a spore kill rate of 4 log. According to the International High Pressure Food Association, the global HPP equipment market is projected to exceed $4.2 billion by 2028, with the Asia-Pacific region accounting for 38%.

With the explosive growth in consumer demand for "clean labels," 612L ultra-high pressure HPP sterilization equipment is redefining the threshold of food safety. Its technological extensibility extends beyond sterilization; its potential applications in texture reconstruction and active ingredient extraction may give rise to a new generation of food processing paradigms.
