AI Technical Summary

Technical Problem

Existing off-site sterilization tank cooling components have poor cooling performance, the coolant absorbs heat slowly, and are inconvenient to use.

Method used

It adopts a jacketed directional liquid cooling assembly, using a diaphragm pump to deliver coolant to the spiral flow channel. The coolant rises to the top in the spiral flow channel and flows out, then flows in the opposite direction to the surface of the cooling tank and circulates below the partition ring. Combined with springs, conical blocks and sealing discs, high-pressure gas supply is achieved, eliminating the need for an external gas source.

Benefits of technology

It improves heat exchange efficiency, enables rapid cooling, simplifies the gas supply process, and enhances the efficiency and convenience of the cooling components.

Abstract

This application discloses a jacketed directional liquid cooling assembly, relating to the field of jacketed fermenters. It includes a tank body, a stirring device, a discharge port, a feed port, a jacket, a cooling assembly, a gas outlet pipe, and a gas limiting assembly. A diaphragm pump delivers coolant to a spiral flow channel. When the coolant rises to the top of the spiral flow channel, it flows out through an opening at the top and then naturally flows down through the gap between two adjacent spiral flow channels by gravity. This achieves cooling of the tank's outer surface by two coolants flowing in opposite directions, improving heat exchange efficiency. The flowing coolant can return to the bottom of the separating ring for the next cooling cycle. A spring, a conical block, and a sealing disc ensure sealing before the gas pressure reaches the required level. Once the gas pressure reaches the required level (sterilization complete), high-pressure gas is directly delivered to the diaphragm pump through an inclined pipe, eliminating the need for an external gas source.
