Product Name: Modified Atmosphere Packaging (MAP) Machine
I. Product Overview
The Modified Atmosphere Packaging (MAP) Machine is a high-end preservation equipment widely used in the final packaging stage of poultry processing. It is designed to preserve the original color, texture, and nutritional value of fresh poultry products by modifying the atmospheric composition around the meat. As global consumers increasingly demand fresh, non-frozen meat, this machine has become a core component of industrialized cold-chain logistics. Its structural design emphasizes high automation, precision gas mixing, and compliance with the most rigorous international food safety guidelines, representing the advanced trend in modern food engineering.
II. Functions & Workflow
The core function of the MAP machine is to replace the air inside the food tray with a precisely calculated mixture of protective gases, typically Carbon Dioxide, Nitrogen, and Oxygen. The workflow begins with the placement of poultry portions into trays, which then enter a vacuum chamber. After extracting the air, the system injects the customized gas mixture and immediately seals the tray with a high-barrier film. This process solves the problem of rapid oxidation and microbial spoilage common in traditional packaging. By inhibiting aerobic bacteria and mold, the system ensures that the poultry remains “fresh-slaughtered” in appearance and taste for a much longer period, avoiding weight loss and maintaining the integrity of the product during transport.
III. Materials & Build Quality
To meet the stringent hygiene requirements of meat packing halls, the entire frame and casing of the MAP machine are constructed from premium SUS304 stainless steel. All contact components are made from food-grade materials that are resistant to corrosion and chemical sanitizers. The internal molds are high-precision components made from high-strength aluminum alloy or stainless steel, treated for anti-stick properties to ensure smooth film release. The machine is specifically designed to operate reliably in the cold and damp environments of packaging workshops, featuring high-quality electrical components housed in waterproof enclosures to ensure a long operational lifespan and ease of maintenance.
