AI Technical Summary

Technical Problem

In the current soy milk production process, the generation of bubbles damages the taste and flavor of the soy milk. At the same time, the introduction of vacuum equipment increases the system complexity, cost and energy consumption.

Method used

By controlling the liquid level, the material and water are kept at a level higher than the discharge port during the feeding process, preventing air from entering the grinding device and achieving deoxygenated grinding.

Benefits of technology

No vacuum equipment is needed, which reduces system complexity and energy consumption, reduces foam generation, reduces cleaning difficulty and spill risk, and improves the taste and flavor of soy milk.

Abstract

The application discloses an oxygen-isolating double-wall-breaking grinding system, which comprises a feeding container, a feeding device and a grinding device. The feeding container is configured to obtain material and water. The feeding device comprises a shell and a feeding member arranged in the shell. The grinding device is configured to grind the material and water. The feeding container has a discharge port in communication with the shell. When the feeding member delivers the material and water to the grinding device, the liquid level in the feeding container is always higher than the discharge port, so that air cannot enter the grinding device through the feeding device. Compared with the prior art, the oxygen-isolating double-wall-breaking grinding system does not need a vacuumizing device, and oxygen isolation is realized only by liquid level control, so that the cost is reduced, the structure is more compact, and the required energy consumption is lower. The whole grinding system is isolated from air, foam generated in the grinding process is reduced, and thus the cleaning difficulty and the overflow risk are reduced.
