With the progress of the times, the increasing complexity and variety of products has also increased the functionality of packaging. The wave of high technology has pushed packaging to a higher level of development, and modified atmosphere packaging (MAP) technology will undoubtedly have a place in the era of intelligent packaging. As some food and fruit/vegetable preservation products are increasingly becoming the mainstream of food consumption and occupy an ever-growing share of the domestic and international markets, applying MAP technology to food preservation can greatly extend the shelf life of food, thus having great market potential.
The principle of the compound gas modified atmosphere preservation packaging machine is a new type of food and fruit/vegetable preservation packaging equipment developed based on vacuum packaging machines and nitrogen flushing packaging machines. Its most prominent feature is solving the problem of significant damage to the taste and quality of food after vacuum packaging and high-temperature sterilization, as well as the issue of requiring sterile packaging for nitrogen flushing which involves a large investment. Through compound gas modified atmosphere packaging, it ensures the original taste and flavor of the food, preserving its natural essence and appearance.
The MAP-1Z350 fully automatic gas modified atmosphere preservation packaging machine produced by Shanghai Ju Gang Machinery Manufacturing Co., Ltd. adopts integrated control of machinery, electricity, and pneumatics. The automatic control system consists of a world-leading Japanese Omron programmable logic controller (PLC) and touch screen (programmable human-machine interface) along with relevant electrical components. Operations such as gas mixing, gas replacement, thermal sealing and cutting, thermal seal film winding/unwinding, and material mold conversion are all automatically controlled by a microcomputer. The user interface is friendly, and each step of the packaging process can be freely adjusted and set according to need via the touch screen. All actions and parameters are set, modified, and controlled by the PLC, making the operation convenient, reliable, and reducing the failure rate. The frame and other components are all made from food-grade 304 stainless steel, meeting food hygiene requirements.
