AI Technical Summary

⚠Technical Problem

Existing stirring systems face challenges in maintaining a uniform mixture during discharge and minimizing air entrainment, particularly when the liquid level decreases, leading to uneven mixing and quality issues such as concentration variations and oxidation.

⚗Method used

A stirring system with a rotatable stirring blade that adjusts its rotation speed based on the liquid level, incorporates a suppression mechanism to minimize uneven mixing and air entrainment, and includes features like baffles, negative pressure, and discharge assistance to maintain uniformity.

🎯Benefits of technology

The system ensures a uniform mixture discharge while reducing air entrainment, preventing quality deterioration and concentration variations, even as the liquid level decreases.

Abstract

To provide a stirring system that can maintain a uniform mixture even when dispensing the mixture while rotating stirring blades in a stirring tank, and can reduce air entrainment into the mixture.SOLUTION: Provided is a stirring system in which rotatable stirring blades 2 are arranged in a stirring tank 1 and a mixture is discharged (B) from a bottom part of the stirring tank, the stirring system being characterized by having suppressing means that allows the mixture to be discharged (B) while rotating the stirring blades 2 and suppresses the mixing unevenness of the mixture discharged by the stirring blades 2 as the height of the liquid level (LEV) of the mixture in the stirring tank 1 is lowered. For example, rotation adjusting means 5 is provided that adjusts the rotational speed of the stirring blades 2 according to the amount (liquid level LEV) of liquid remaining in the stirring tank 1.SELECTED DRAWING: Figure 3
