Germ-free vacuum packing device applicable to irregular block-shaped meat

Abstract

The invention relates to a germ-free vacuum packing device applicable to irregular block-shaped meat. The packing device comprises an air filter device and a germ-free working cabin, wherein a vapor sterilizing trough, a weighing device and a vacuum packing machine are also arranged inside the germ-free working cabin, the vapor sterilizing trough is fixed on the outer side of a material inlet and a material outlet of the germ-free working cabin; the weighing device is arranged inside the germ-free working cabin to be close to the material inlet; and the vacuum packing machine is fixedly arranged on the right side of the weighing device to be close to the material outlet of the germ-free working cabin. Due to adopting the germ-free vacuum packing device integrating the germ-free technology and the vacuum packing technology, meat materials with irregular shape can be segmented, weighed and vacuum packed in a germ-free environment, so that the natural flavor of the meat can be maintained.

Description

technical field [0001] The invention relates to food preservation technology, and relates to an aseptic vacuum packaging device, in particular to an aseptic vacuum packaging device suitable for irregular block-shaped meat products. Background technique [0002] The concentration of microorganisms in natural air is about 10 to 100 billion per cubic meter. The concentration of microorganisms in meat production workshops is higher than that in natural air due to the enrichment of nutrients required for the growth and reproduction of microorganisms. The filling, weighing and sealing of stuffed products such as sausage and ham in meat products have a high degree of automation, and can be completed in a closed environment, and it is easy to realize aseptic vacuum packaging. However, the weighing, filling, and vacuuming of irregular block-shaped meat materials such as meat pieces and ribs are usually completed in an exposed environment, and the degree of secondary pollution is seri...

AI Technical Summary

Problems solved by technology

However, the weighing, filling, and vacuuming of irregular block-shaped meat materials such as meat pieces and ribs are usually completed in an exposed environment, and the secondary pollution is serious.

At present, high temperature and high pressure (121°C, 30 minutes) sterilization is commonly used at home and abroad, but this method is not easy to maintain the original flavor of the product; packaging food under aseptic conditions is also a feasible method, but at present The function of the aseptic operation box is simple, the space is small, and only simple packaging can be carried out

For example, CN201800971U discloses a disinfection and sterilization treatment device for an aseptic packaging system, which includes an air filter device and a sterile working cabin. The air is sent into the sterile working cabin through the air filtering device. The nozzle and ultraviolet lamp, the atomizing nozzle is connected to the hydrogen peroxide device. This sterilization treatment device has a good aseptic operation function, but it can only carry out simple normal pressure packaging in it, and cannot simultaneously complete weighing and vacuum under aseptic conditions. All-in-one operation
