Description

Continuous sterilization system

Technical Field

The invention relates to the technical field of sterilization devices, in particular to a continuous sterilization system.

Background

With the rapid development of the food industry, the technical requirements for assembly line equipment in the field of food machinery are increasing day by day. The existing continuous sterilization system comprises a bottle and can sterilization device, a bottle and can conveying device, a can erecting device, a can body single-row device and a detection turnover device.

When the cauldron that disinfects among the current sterilizing equipment carries out steam sterilization to the bottle jar, at first let in hot water in to the cauldron that disinfects, hot water begins to carry the bottle jar in to the cauldron that disinfects after advancing the water level of setting for in the cauldron that disinfects, and the bottle jar passes through hydrothermal cushioning effect and constantly gets into in the cauldron that disinfects, and the product preheats through hot water, and along with the product of putting into more and more, the hot-water liquid level constantly risees in the cauldron that disinfects, and hot water can be discharged the cold air in the cauldron that disinfects. When the product is subjected to steam sterilization, hot water in the sterilization kettle needs to be emptied, and then steam is injected into the sterilization kettle. In the prior art, hot water entering a sterilization kettle is recycled, and the hot water can continuously exchange heat with the outside through a pipeline in the conveying process, so that part of heat is dissipated into the air; the hot water gets into disinfect the cauldron after and disinfect the cauldron and disinfect the product in the cauldron and carry out the heat exchange, the lower cover device setting of cauldron of disinfecting is at normal atmospheric temperature inslot, and the heat in the cauldron of disinfecting can scatter and disappear along with the heat exchange of the water in lower cover device and the normal atmospheric temperature basin, causes the temperature drop in the cauldron of disinfecting, and hydrothermal temperature drop, the method that generally adopts for solving above-mentioned problem is: after cold air in the sterilization kettle is discharged through the hot water, steam is introduced into the sterilization kettle to discharge the hot water, and then the discharged hot water is heated to reach the temperature required by the next discharge of the cold air in the sterilization kettle, so that the energy consumption is increased.

The bottle after the bottle sterilizing device disinfects discharges from the cauldron that disinfects and carries cooling in to the basin, and conveyor in current basin and the basin is the straight line and arranges, occupies great space on length direction, requires that the workshop place must have sufficient length, does not solve above-mentioned problem, sets up the conveyor in basin and the basin into the form that the bend was carried, but through the turn, the product after disinfecting distributes inhomogeneously.
