Description

Technical Field

[0001] The utility model relates to the technical field of fruit juice production and processing, in particular to a vacuum degassing tank for fruit juice production and processing. Background Art

[0002] During the production and processing of juice, due to the presence of oxygen, carbon dioxide and other gases in the intercellular spaces of the fruit, these gases can enter the juice in a dissolved state or be absorbed on the surface of pulp particles and colloids during the processing of juice. Therefore, the juice needs to be degassed to prevent oxidation of the juice and extend the storage period of the juice, which involves the use of vacuum degassing tanks.

[0003] For example, publication number CN211659327U discloses a vacuum degassing tank for food processing, comprising a tank body, wherein the tank body is provided with an exhaust mechanism for vacuum degassing, wherein the interior of the tank body is provided with a degassing chamber, wherein a tank cover is fixedly engaged with the top of the tank body, wherein a feed pipe is fixedly connected to the top of the tank cover, wherein the feed pipe penetrates the tank cover and extends to the bottom thereof, wherein a connecting pipe is screwedly fixedly connected to the inner wall of the feed pipe, wherein the other end of the connecting pipe is fixedly connected with an extension pipe; wherein the travel of the juice in the degassing chamber is increased, thereby making the degassing time of the juice uniform, allowing the gas contained in the juice to fully dissipate, and the induced draft fan works to induce the gas generated by the juice to a condensation box for condensation and cooling treatment, thereby making the moisture contained in the air and the aromatic substances in the juice combine to form a liquid that enters the juice, thereby avoiding the loss of the aromatic substances in the juice and ensuring the quality of the juice;

[0004] The vacuum degassing tank for juice production and processing in the utility model lacks the function of stirring the juice. After the juice gathers at the bottom of the tank, there is still a certain amount of air in the liquid, resulting in low overall degassing efficiency of the juice. At the same time, there is a lack of drainage structure on the inner wall of the tank, which causes the juice to easily adhere to the surface of the tank after spraying and degassing, which is not conducive to the subsequent unloading of the juice and the cleaning and maintenance of the tank.
