Introduction to box-type modified atmosphere packaging machine
The box-type modified atmosphere packaging machine is a device that completes sealing and packaging by automatically vacuuming and filling with a specific mixed gas. It is widely used in food, medicine and other industries to extend the shelf life of products and improve packaging quality.
1. Working principle
The working process of the box-type modified atmosphere packaging machine is as follows: after the product is placed in a prefabricated box, the equipment sends the box into the sealing mold through a chain. The mold rises, attaches the upper film to the sealing surface of the box, first vacuums, and then fills with nitrogen, carbon dioxide and other mixed gases according to user needs, then performs hot pressing sealing and cutting, and finally exhausts the gas and lowers the mold to complete the packaging. The whole process is highly automated to ensure packaging efficiency and quality.
2. Equipment classification
Fully automatic modified atmosphere packaging machine: suitable for boxed and bowled products, suitable for small-volume food industries. After manual box placement, the box is automatically taken out, with an output of 600-1000 boxes/hour.
Continuous box-type modified atmosphere packaging machine: also suitable for boxed and bowled products, but designed for large-volume food industries. After the box is placed manually, it works automatically and continuously, and the output can reach 1000-3000 boxes/hour.
Skin packaging machine: It is mainly used for skin packaging of meat, seafood and poultry, and the output is customized according to the size of the box.
3. Technical features
Highly automated: The equipment adopts imported programming control system, color simulation touch screen, electrical appliances, pneumatic valves and solenoid valves and other components, which are convenient and reliable to control and have low failure rate.
Efficient production: After the packaging box filled with items is introduced into the conveyor, it can automatically and continuously complete the processes of vacuuming, inflation, hot pressing sealing, slitting, and pushing out the finished packaged products, with high production efficiency.
High packaging quality: The photoelectric system ensures the integrity of the cover film pattern, and has a box-free shutdown protection function to ensure the quality of the finished product.
Excellent material: The main components such as the frame are made of SUS304 stainless steel, which meets the hygiene requirements.
Flexible mold: The mold shape can be configured according to the packaging box shape selected by the user, and it has strong adaptability.
4. Application field
Box-type modified atmosphere packaging machine is widely used in vegetables, fruits, cold fresh meat, seafood, cooked food products and other fields. For example, in the packaging of fresh meat, by filling a specific proportion of carbon dioxide, nitrogen and oxygen, the shelf life can be extended and the color and taste can be maintained. In the packaging of fruits and vegetables, by adjusting the gas composition, respiration can be reduced, and the ripening and decay process can be delayed.
5. Equipment advantages
Extend shelf life: By accurately controlling the gas composition in the package, reducing the oxygen content, increasing the proportion of inert gases such as carbon dioxide and nitrogen, inhibiting the growth of microorganisms, and extending the shelf life of the product.
Improve packaging efficiency: high degree of automation, reducing manual operations, and improving production efficiency.
Save labor costs: only a small number of operators are needed to complete production tasks, reducing the labor costs of enterprises.
Increase product added value: exquisite packaging design can increase product attractiveness and added value, which is conducive to brand building and promotion.
Environmental protection and energy saving: using advanced packaging materials and technologies to reduce pollution to the environment and save energy resources.
