Food vacuum packaging machine with sterilization function

Abstract

The invention discloses a food vacuum packaging machine with a sterilization function. The food vacuum packaging machine comprises a bottom plate, an ultraviolet sterilization mechanism and a high-temperature instantaneous sterilization mechanism, wherein a supporting column, a vacuum mechanism, a main controller and a conveying belt are arranged on the upper portion of the bottom plate, a power source of the conveying belt is driven by a motor, and the supporting column is arranged on one side of the main controller. According to the food vacuum packaging machine, two vacuum machines are arranged, negative pressure is provided for the whole processing environment, a vacuum environment is extracted for a packaging bag sleeved with a steel belt, so that food is further protected, the bacterial activity is reduced, and sterilization work is completed indirectly; the ultraviolet sterilization mechanism and the high-temperature instantaneous sterilization mechanism are arranged, and the food is sterilized through ultraviolet irradiation sterilization and high-temperature instantaneous steam sterilization, so that the storage life of the food is prolonged, and the food safety is improved; and signals are transmitted to the main controller through an infrared displacement sensor and a temperature detector, so that the displacement speed of the conveying belt and a first heater can beconveniently controlled, the overall working precision is improved, and then the sterilization performance is improved.

Description

technical field [0001] The invention relates to the production field of food-grade vacuum packaging machines, in particular to a food vacuum packaging machine with a sterilization function. Background technique [0002] Food vacuum packaging Put food into the packaging bag, extract the air in the packaging bag, and complete the sealing process after reaching the predetermined vacuum degree. In the food industry, vacuum packaging is very common. Various cooked products such as chicken legs, ham, sausages, grilled fish Chips, beef jerky, etc.; pickled products such as various pickles, soy products, preserved fruits and other foods that need to be kept fresh are more and more vacuum-packed. The food that has been vacuum-packed has a long shelf life, greatly extending the shelf life of food . [0003] Food sterilization is to take food raw materials and processed products as the object, through the main factor causing food deterioration---microbial sterilization and sterilizati...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing food vacuum packaging machines and food sterilization equipment adopt the splicing method, that is, the same equipment generally does not have the above two functions, the processing technology is relatively complicated, and most of the existing sterilization equipment is in a conventional environment. During the process, bacteria in the air may still multiply on the food, therefore, a food vacuum packaging machine with sterilization function is needed
