The JKGK-1100A operates in a cyclical manner using a crawler conveyor belt, enabling continuous batch sealing of products. The operator only needs to place the packaged bags containing the materials on the conveyor belt, and the machine will automatically complete the entire process of conveying, vacuuming, sealing and unloading. Compared to traditional single/double chamber vacuum machines, its advantages include no need for manual opening of the lid; adjustable worktable angle; timed conveyor belt movement; and automatic opening and closing of the vacuum chamber lid.
