High-voltage electric field and low-temperature plasma cold sterilization production line equipment

Abstract

The invention discloses high-voltage electric field and low-temperature plasma cold sterilization production line equipment. The high-voltage electric field and low-temperature plasma cold sterilization production line equipment comprises a machine case, a rack, a conveyor belt mechanism, high-voltage electric field and low-temperature plasma cold sterilization core devices, a high-voltage transformer, a high-voltage control cabinet, high-voltage electric field shielding doors and a control device. The high-voltage electric field and low-temperature plasma cold sterilization core devices are arranged in the machine case above the rack and 2 to 5 groups of the high-voltage electric field and low-temperature plasma cold sterilization core devices are arranged at a certain distance along a movement direction of the conveyor belt mechanism; each high-voltage electric field and low-temperature plasma cold sterilization core device is composed of a plurality of groups of high-voltage electrode assemblies which are arrayed in one row in parallel at an equal distance; the high-voltage electric field shielding doors are arranged at an entrance and an exit of a sterilized packaging part on the rack respectively in a hoistable manner. The high-voltage electric field and low-temperature plasma cold sterilization production line equipment is used for carrying out a plurality of times of low-temperature plasma continuous sterilization treatment on a packaging product; the sterilization time is short, the effect is good, and the efficiency is high; a sterilization procedure is accurate and controllable, is simple to operate and can be adaptive to automatic production requirements of large-scale cold sterilization and fresh-keeping packaging of foods.

Description

technical field [0001] The invention relates to the technical field of food sterilization, in particular to a high-voltage electric field low-temperature plasma cold sterilization production line equipment. Background technique [0002] Compared with the currently widely used food sterilization technology, the high-voltage electric field low-temperature plasma cold sterilization technology is an important breakthrough in the food cold sterilization and fresh-keeping packaging technology; this technology can be perfectly combined with the MAP modified atmosphere fresh-keeping packaging technology, and the low-temperature plasma can sterilize the packaged products The treatment will not produce secondary pollution, and the plasma that produces the sterilizing effect comes from the gas inside the package, which will not produce chemical residues and has high safety; although the voltage used is very high, the current is small, the sterilizing process is very short and no heat wi...
