Description

Technical Field

[0001] The present invention relates to the technical field of turnover systems, and particularly to an automated sterilization turnover system for canned foods. Background Art

[0002] The traditional sterilization process for diced tomatoes uses water bath sterilization, which includes a degassing tank, a sterilization tank, and a cooling tank. After pre-sealing, canned foods enter a 20-meter-long degassing tank to heat up and degas, which takes about 45 minutes. After heating up, they enter the sterilization tank, where steam is directly injected into the tank, and the steam is controlled by a regulating valve to heat the water to a predetermined temperature. Then, the diced tomato products are sterilized by being conveyed through a mesh chain, which takes about 1.5 hours. Then, they enter the cooling tank, where they are cooled by circulating cooling water, which takes about 1 hour. After that, they are sealed. The whole process takes 3 hours and 15 minutes. Moreover, during the sterilization and cooling sections of the water bath sterilizer, the production water consumption is large. If product leakage occurs during transportation, it is easy to cause water quality pollution, and at the same time, it will leave marks on the product appearance, affecting the product quality. In addition, the water bath sterilizer has low efficiency and low steam utilization rate, resulting in increased gas consumption and a significant increase in cost. Not only that, the whole equipment is large in volume and occupies a large area. The specifications of the degassing tank are 2000*1800*20000mm, the specifications of the sterilization tank are 3000*1200*30000mm, and the specifications of the cooling tank are 3000*1200*26000mm. The total length of the whole facility reaches 56 meters, and the equipment occupies 30% of the factory building area. During the water bath sterilization process, there is a situation of backflow, which requires arranging multiple people to hold the cans, with a large working intensity. Therefore, the labor cost of traditional equipment is relatively high, the labor intensity is relatively large, and it will increase the cost required for construction investment.

[0088] When T4 < ΔT, the fourth preset correction coefficient m4 is selected to correct Ai, and after correction, it is Ai(ai * m4, bi * m4).

[0089] Specifically, a preset correction coefficient is selected according to the relationship between the real-time pressure ΔT of the steam in the high-pressure sterilizer and the pressures T of the steam in each preset high-pressure sterilizer to correct the working conditions in the i-th preset working condition matrix Ai, so as to ensure that the amount of steam in the high-pressure sterilizer can achieve the purpose of normal disinfection and sterilization and improve the sterilization efficiency.
