Circulating device for enhancing sterilizing effect of tube array type juice sterilizing and filling machine

Abstract

The invention discloses a circulating device for enhancing a sterilizing effect of a tube array type juice sterilizing and filling machine. A conventional tube array type juice sterilizing and filling machine cannot realize low-temperature short-cycle operation; the short-cycle operation can ensure that juice can reach a sterilizing temperature before filling; however, part of the juice usually cannot reach the sterilizing temperature during production, and the filled juice has risk of microorganism pollution. According to the circulating device, a low-temperature juice backflow tube is arranged between a juice heating system and a secondary juice cooling system; a cyclic steering valve capable of implementing the operation according to a temperature instruction is arranged in the low-temperature juice backflow tube. Therefore, a system starts the cyclic steering valve to work if the temperature of the juice is lower than a set temperature point in a production process, so that the juice cannot reach the secondary juice cooling system and flows back to the juice heating system through a primary juice cooling system to form a new cycle; pollutions, which are possibly caused by a fact that the juice cannot reach the sterilizing temperature, to the subsequent system are avoided, and the possible risk in the quality of a product is reduced.

Description

technical field [0001] The invention relates to a circulation device for improving the sterilization effect of a tubular fruit juice sterilizing and filling machine, and belongs to the technical field of fruit juice sterilizing and filling equipment processing. Background technique [0002] In the fruit juice sterilizing and filling process of fruit juice production enterprises, the commonly used equipment is the tube-type sterilizing filling machine. The principle of the tube-type sterilizing filling machine is: the juice is heated in the heating tube until the temperature reaches 95- 130°C, after 90-120 seconds under this condition, the sterilization effect will be achieved, the hygienic indicators in the juice will meet the requirements, and the product will not deteriorate and produce gas during storage. However, in actual production, the existing tube-and-tube sterilizing filling machine has defects, and cannot realize low-temperature short-cycle operation. The short cy...
