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.
