This utility model discloses a sealing device for pre-
processed meat, belonging to the technical field of sealing equipment. The technical solution includes a base plate, a sealing
barrel, and a lid fitted over the sealing
barrel. The sealing
barrel is located on top of the base plate, and the lid and sealing barrel are connected by a snap-fit. A through groove is provided on one side of the lid. A
vacuum pump is located on the top of the base plate. A
pipe is fixedly embedded on one side of the sealing barrel, passing through the through groove. A one-way valve is installed on the
pipe, and a flexible hose is fixedly connected to the
vacuum pump. The beneficial effects of this utility model are: the design of the
vacuum pump, and the connection between the vacuum pump and the sealing barrel via the
pipe and flexible hose, allows for vacuuming of the sealing barrel by controlling the vacuum pump during use, reducing the
oxygen concentration within the sealing barrel. This enables vacuum preservation of the meat, maximizing the inhibition of aerobic microbial growth and effectively delaying
fat oxidation and meat discoloration.
