Description

Technical Field

[0001] The utility model belongs to the technical field of enzyme preparation activation, and in particular relates to an enzyme preparation heat preservation and stirring device. Background Art

[0002] Enzyme preparations refer to biological products with catalytic functions after the enzymes have been purified and processed. They are mainly used to catalyze various chemical reactions in the production process. They have the characteristics of high catalytic efficiency, high specificity, mild action conditions, reduced energy consumption, and reduced chemical pollution. The activity of enzyme preparations is affected by temperature, pH value, and enzyme concentration. Only at the appropriate temperature, pH value, and substrate concentration can the activity of enzyme preparations be good and the catalytic efficiency be high.

[0003] For example, a Chinese patent (authorization announcement number: CN 214060522 U) discloses a circulation pipeline temperature control device for enzyme preparation production, including a fermentation tank, wherein the four corners of the lower end of the fermentation tank are fixedly equipped with supporting feet, the middle of the lower end of the fermentation tank is fixedly equipped with a stirring device, the inner side wall of the fermentation tank is fixedly equipped with a pure air introduction device, the upper end of the fermentation tank is fixedly equipped with a feeding device, the four corners of the fermentation tank are fixedly equipped with temperature sensors, the side wall of the fermentation tank is embedded with an electric heating rod, the left bottom end of the fermentation tank is fixedly equipped with a control box, and the left side of the control box is fixedly equipped with a liquid crystal display screen; a stirring device is arranged in the tank body in this scheme, and nozzles are evenly arranged around the tank wall to allow the material in the tank to contact with the air more fully and increase the dissolved oxygen efficiency. A corrugated hose and a water tank are arranged at the feed inlet. After adding materials, the corrugated hose is placed in the water tank to prevent bacteria from entering the tank body. Electric heating rods are arranged on both sides of the tank body to adjust the temperature in the tank body in time and improve the fermentation efficiency.

[0004] However, in the above scheme, only the ambient temperature of the enzyme preparation is adjusted, and the activity of the enzyme preparation will still be affected by the pH value, substrate concentration and reaction time. The temperature is transferred to the tank through the tank wall, which will cause uneven heating and cause local enzyme preparation to be inactivated during the heating process. The mixing tank is a relatively closed environment, and conventional cleaning tools cannot enter the mixing tank. Cleaning inside the mixing tank is also a difficulty. Utility Model Content
