Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biological fermentation and extraction, and particularly relates to an enzymatic hydrolysis device applied to corn steep liquor. Background Art
[0002] Enzymatic hydrolysis is the process of breaking down macromolecular compounds into small molecular compounds. It is an important part of biological fermentation. During the enzymatic hydrolysis process, time, stirring, temperature, pH value, etc. are important control indicators.
[0003] Currently, enzymatic hydrolysis equipment primarily consists of an enzymatic hydrolysis tank, along with temperature control and feeding equipment. The enzymatic hydrolysis tank is a vertical stainless steel tank with an internal stirring device. During the enzymatic hydrolysis of corn slurry, fixed components and precipitates within the mash precipitate, resulting in stratification within the tank. Excessive stirring can affect the enzymatic hydrolysis process, resulting in poor results.
[0004] Application number: 2023205859088, discloses an enzymolysis device with an improved structure, an enzymolysis device with an improved structure, comprising an enzymolysis tank, the enzymolysis tank being provided with a discharge port and a feed port, the enzymolysis device also comprising a stirring member arranged in the enzymolysis tank, the stirring member comprising a first drive motor, a stirring rod, a screw rod and a limiting cover, the first drive motor being arranged above the enzymolysis tank, the screw rod being arranged in the enzymolysis tank and one end of the screw rod being connected to the first drive motor, the limiting cover being sleeved on the screw rod and the inner wall of the limiting cover abutting against the outer wall of the screw rod, the stirring rod being annularly arranged on the outside of the limiting cover, the spiral rod and the limiting cover ensuring that the raw materials can be cyclically flipped up and down, the stirring rod ensuring that the raw materials can be flipped in the horizontal direction, and ultimately ensuring that the raw materials can be flipped up and down, left and right during enzymolysis, thereby making the enzymolysis more sufficient.
[0005] The above scheme uses a spiral rod and a limit cover to ensure that the raw materials can be circulated up and down. The vibration amplitude of the spiral rod is large, which affects the enzymatic hydrolysis effect. In addition, some additives need to be added during the enzymatic hydrolysis process, generally by pipe dripping. Due to slow stirring, the additives cannot be quickly and evenly distributed in the solution, which is inconvenient to use. Utility Model Content
