Grinding, degassing and discharging tank for juice production

Abstract

The invention discloses a grinding and degassing discharge tank for fruit juice production, which comprises a discharge cylinder, a juice degassing tank, a grinding hopper, a grinding roller and a nitrogen storage tank, and the bottom side of the juice degassing tank is welded on a frame The inner wall of the upper end of the juice degassing tank is welded with a grinding hopper, the fruit juice degassing tank on the upper part of the grinding hopper is set as a juice distribution cavity, the juice degassing tank on the lower part of the grinding hopper is set as a stirring cavity, the juice A rotating shaft is installed vertically in the middle of the degassing tank, and the rotating shaft passes through the through hole of the rotating shaft in the middle of the grinding hopper; it effectively prevents the juice from being oxidized when sprayed into the juice distribution chamber, contacting oxygen, etc., improves the stability of the juice quality, and has a good grinding effect; It is convenient for oxygen, carbon dioxide and other gases in the pulp cell gap of the juice to escape; to avoid the precipitation and stratification of the pulp in the juice, to improve the uniformity of the juice, to facilitate the degassing treatment of the gas in the juice; to realize the rapid discharge of the juice.

Description

technical field [0001] The invention relates to the technical field of fruit juice production equipment, in particular to a grinding, degassing and discharging tank for fruit juice production. Background technique [0002] In the production of fruit juice, due to the presence of gases such as oxygen and carbon dioxide in the intercellular space of the fruit, it can enter the fruit juice in a dissolved state during the fruit juice processing process, or be absorbed on the surface of the pulp particles and colloids. During the pulp crushing process, The contact surface between the fruit juice and the atmosphere increases, which increases the gas content, so degassing is required, especially in turbid juices, degassing can reduce or avoid the oxidation of juice components; methods to reduce the change of juice color and flavor, and degassing are Vacuum method, nitrogen exchange method and antioxidant method, etc.; vacuum method is that the juice is dispersed into a thin film or...

Problems solved by technology

[0003] However, when the existing fruit juice vacuum degassing equipment is in use, due to the negative pressure caused by the vacuum, the juice is not smooth during the discharge process.

When the fruit juice is added to the degassing tank, because the fruit juice contains pulp with different particle sizes, it not only affects the effect of degassing, but also may cause blockage during discharge. Chinese patent (authorized announcement number: CN206284305U) discloses a Juice degassing equipment, although all can realize the degassing treatment of juice; however, after the juice is passed into the degassing tank, it cannot effectively treat the pulp with different particle sizes in the juice, and only filters through the filter frame for a long time. Time to filter out the large-grained pulp will cause blockage, resulting in production interruption; and the filtered large-grained pulp cannot be ground into small particles to enter the degassing process

[0004] During the degassing process, the lack of necessary stirring process will cause the gas such as oxygen and carbon dioxide in the pulp cell space of the juice to be unable to escape from the static juice, and it will easily lead to precipitation and stratification of the juice, resulting in the loss of pulp in the juice. Small particles are unevenly distributed up and down, which affects the quality of juice production; and the juice is discharged directly through the discharge pump. Once the juice is immersed in the pump body, it will not only cause the juice to be polluted, but also cause the pump body to corrode; it is not suitable for juice discharge, unable to achieve quantitative discharge output of juice
