KBT1200 Series – Medium to Large Capacity Freshness Solution. Advanced Freshness Technology for Continuous Food Production
High Efficiency. Stable Output. Automated Rotary Design.
The KBT1200 Series Rotary Modified Atmosphere Packaging Machine is designed for medium to large production capacities, delivering stable, continuous MAP tray sealing with a rotary mold system. It is suitable for packaging food products in pre-made plastic containers of various sizes and shapes, including trays, bowls, and cups (rectangular, square, round, triangular, etc.).
By replacing ambient air inside the package with a controlled gas mixture, the KBT1200 Series can extend product shelf life by 50%–500%, while preserving natural color, texture, and taste—without artificial preservatives.
Core Selling Points:
Rotary Mold System: Enables continuous operation with higher efficiency than linear or single-station machines.
Medium to High Capacity Output: Ideal for growing food factories and central kitchens.
Clean Label Preservation: Extends freshness naturally without chemical additives.
Flexible Automation Options: Standard automatic tray unloading, optional automatic tray loading.
The KBT1200 Series applies the proven Vacuum – Gas Filling – Sealing MAP process:
Vacuum: Air is evacuated from the tray to remove residual oxygen.
Gas Filling: Pure gas or a precise mixture of food-grade gases (N₂, CO₂, O₂, or others) is injected.
Sealing: The tray is hermetically sealed with top film to lock in the modified atmosphere.
Compared with traditional gas flushing methods, this process ensures higher gas purity, reduced gas consumption, and more consistent shelf-life performance.
Rotary Automation: Rotary molds combined with conveying belts allow smooth tray transfer and stable rhythm.
Reliable Vacuum Performance: Equipped with a BUSCH vacuum pump for consistent vacuum efficiency.
High Hygiene Standard: Food-grade SUS304 stainless steel construction meets strict food safety regulations.
Precision Control: Mitsubishi PLC, servo motors, and temperature control ensure sealing accuracy and stability.
The KBT1200 Rotary MAP Packaging Machine is widely used across fresh and semi-fresh food sectors:
Beef, pork, lamb, chicken
Maintains fresh color and extends shelf life
Fresh fish fillets, shrimp, shellfish
Prevents deformation and protects delicate textures
Cooked meals, convenience foods, deli products
Pastries, desserts, and portioned fresh foods
