Temperature control system for liquor fermentation pit

Abstract

The invention discloses a temperature control system for a liquor fermentation pit. The temperature control system comprises a pit pool, a water supply tank, and a controller, a plurality of first temperature sensors are arranged at different positions of sidewalls of the pit, the top of the pit is provided with two servo motors, each servo motor is engaged with a transmission connecting rod, the transmission connecting rods extend into the pit, the outsides of the transmission connecting rods are provided with a plurality of mutually-sleeved telescoping sleeves, the bottom ends of the last telescoping sleeves are respectively provided with a tooth-shaped temperature-control plate, a tooth-shaped area of one tooth-shaped temperature-control plate and a gap area of the other tooth-shaped temperature-control plate are arranged in an opposite manner, the width of the gap area is greater than the tooth-shaped area, the tooth-shaped area of the tooth-shaped temperature-control plate is provided with a plurality of through holes, the inner part of one tooth-shaped temperature-control plate is provided with heating resistance wires, the inner part of the other tooth-shaped temperature-control plate is provided with a cooling circulating water pipeline, the bottom of each telescoping sleeve is provided with limiting steps, and the inner sides of the limiting steps are provided with sealing layers. According to the temperature control system, the temperature control is uniform and accurate.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a liquor cellar temperature control system. Background technique [0002] Liquor solid-state fermentation is a process in which a cellar is used as a carrier, fermented grains are used as a raw material, natural inoculation, and a variety of microorganisms act synergistically. A series of complex material and energy metabolism processes are carried out in the three phases of solid, liquid, and gas (grass, fermented liquid, and fermented gas) in the cellar. The research shows that temperature has an important influence on the fermentation production of fermented grains. Temperature has an important influence on the growth and metabolism of various microorganisms in the fermentation process of fermented grains. The high-temperature accumulation fermentation process can enrich the types and quantities of microorganisms in the cellar, and can increase the types and contents of micro...

Problems solved by technology

Therefore, controlling the fermentation temperature in the liquor cellar is of great significance to the product quality of the refined liquor. However, the existing methods for controlling the fermentation temperature in the liquor cellar are all to roughly control the entire cellar, and the effect of temperature control is not ideal. There is still room for improvement in yield and quality
