Sealed fermentation device for alcohol production

Abstract

This utility model relates to the field of alcohol production fermentation technology and discloses a sealed fermentation device for safe alcohol production. It mainly includes a fermentation tank with a suction pipe and pump at the top for suctioning and recovering carbon dioxide produced during fermentation and maintaining negative pressure inside the tank. A single-exit valve ensures one-way air intake, preventing contamination from external impurities. The tank is externally wrapped with an insulation layer of insulating material, and a tubular heat exchanger is installed outside the tank. Material is drawn from the tank by a bottom circulation pump and fed into the external heat exchanger for heat exchange, achieving precise temperature control and providing a stable environment for alcohol fermentation. This utility model effectively solves the shortcomings of existing devices in gas handling and temperature control, improving the safety and purity of the fermentation process and ensuring fermentation results and product quality.
