A Thermoforming Modified Atmosphere Packaging (MAP) machine is a specialized piece of equipment used in the food industry for packaging products in a way that extends their shelf life and maintains quality. Here's an overview of how it works and its key components:
1. Thermoforming process:
- Forms plastic film into a desired shape to create the base tray
- Uses heat and vacuum pressure to shape the film
2. Product loading:
- Products are loaded into the formed cavities on the bottom film
3. Gas flushing:
- Removes air from the package
- Replaces with a modified atmosphere (usually CO2, N2, O2)
4. Top film application:
- A second sheet of film is applied over the product-loaded trays
5. Sealing:
- The two films are sealed together under controlled conditions
- Creates an airtight package
6. Cooling:
- Rapid cooling helps set the seal and maintain package integrity
Key features and benefits:
- Extends product shelf life by controlling oxygen levels
- Maintains product freshness and appearance
- Reduces waste and increases distribution possibilities
- Allows for customized atmosphere mixtures
- Can incorporate labels or printed information on packages
- High production speeds for large-scale operations
Common applications include:
- Meat and poultry products
- Seafood
- Dairy products
- Fruits and vegetables
- Ready meals and prepared foods
Equipment Characteristics
1. The frame body is made of high-strength alloy aluminum one-time formation, and is formed by high-precision gantry planing and gantry milling. Compared with the steel structure and normal aluminum plate structure, it has remarkable features such as high mechanical strength, stable structure, no deformation, good precision and so on.
2. This machine adopts imported German BUSCH vacuum pump, which has the features of high pumping efficiency, high vacuum degree, low noise, stable and reliable quality, long service life, etc., and the pumping speed is fast.
3. Equipped with American Banner photoelectric switches, it can package light film and color film, reduce the cost and make the product more upscale.
4. The equipment can be configured with automatic coding system according to the user's requirements, and the printing of packaging date and parameters can be completed at one time during packaging, without manual coding, improving work efficiency.
5. The equipment is equipped with an edge material recycling system, which ensures the hygienic requirements of the user's production environment.
6. The control system of this machine adopts the world renowned Japanese Mitsubishi 10-inch color large-screen touch screen, Omron programmable logic controller (PLC) control stepping system, Mitsubishi servo motor, high operating precision, all actions coordinated automatically and stably, which ensures reliable operation of the machine and easy to use. Push-button switch adopts French "Schneider" electrical company products, with beautiful appearance, safe and reliable operation.
