Abstract
Description
Technical Field
[0001] This utility model relates to the field of food preservation and packaging technology, and in particular to a low-temperature plasma sterilization and modified atmosphere packaging device for fresh meat. Background Technology
[0002] Fresh meat is susceptible to microbial contamination and oxidation during processing, storage, and transportation, leading to quality degradation and shortened shelf life. Among existing preservation technologies, modified atmosphere packaging (MAP) has become the mainstream method by regulating the gas composition within the packaging to inhibit microbial growth and oxidation reactions.
[0003] However, after fresh meat is packaged by modified atmosphere packaging machines, existing equipment mostly adopts the mode of direct transfer after single packaging. Operators need to frequently pick up and put away individual products, which not only increases the labor intensity but also increases the risk of contamination. Furthermore, if the packaged fresh meat is not processed in time, it is exposed to a non-sterile environment during temporary storage, making it susceptible to cross-contamination and affecting the safety of the final product.

[0007] The placement rack includes a support frame, a disinfection rack is provided on the top of the support frame, a placement slot is provided on the support frame, a storage board is placed in the placement slot, and multiple ultraviolet disinfection lamps are evenly arranged longitudinally at the bottom of the disinfection rack.
[0008] In addition, a preferred structure is that a viewing window is provided on the front surface of the insulation shell, and a discharge port and a feed port are respectively provided on both sides of the insulation shell, with plastic curtains provided for both the discharge port and the feed port.
[0009] In addition, a preferred structure is that the temporary storage rack includes a mounting plate, which is fixedly connected to the side wall of the workbench. Support plates are symmetrically arranged at the bottom of the mounting plate, and guide rollers are provided on the upper surface of the mounting plate, with the guide rollers located on one side of the conveyor belt.
