AI Technical Summary
In existing steak coating devices, air may remain between the steak and the packaging film during the sealing process, resulting in a loose coating effect.
A combination of a ring-shaped vacuum pumping mechanism and a hot-pressing mechanism is used. The air between the membranes is extracted by a vacuum pump, and the upper and lower membranes are tightly bonded by the hot-pressing mechanism. The membranes are then heat-fused together by a ring-shaped hot-pressing head.
This achieves a tight bond between the steak and the film, ensuring the coating effect, preventing moisture loss and bacterial contamination, and improving the quality of automated coating processes.
