Description

Technical Field

[0001] This utility model belongs to the technical field of biological fermentation extraction equipment, specifically relating to a concentration device for extracting enzymatically hydrolyzed corn protein through corn steep liquor fermentation. Background Technology

[0002] To extract enzymatically hydrolyzed corn protein through corn steep liquor fermentation, the fermentation broth needs to be concentrated. High-temperature concentration will damage the protein structure and affect product quality, while low-temperature concentration will take a long time and result in low efficiency.

[0003] Application No. 2023225622732 discloses a device for concentrating edible fungus polysaccharide extract, including a concentration tank. A first support base is fixedly connected to the bottom of the concentration tank. A heating coil is sleeved on the surface of the concentration tank. A fixed plate is sleeved inside the concentration tank, and the fixed plate is arranged in a ring. Two scrapers rotate inside the concentration tank, both of which are located at the bottom of the fixed plate. A rotating mechanism for rotating the two scrapers is provided inside the concentration tank. A heat-insulating tank is provided on the surface of the concentration tank, and a second support base is fixedly connected to the bottom of the heat-insulating tank. A heating mechanism for heating the inside of the heat-insulating tank is provided on the surface of the concentration tank. A drainage mechanism is provided at the bottom of the heat-insulating tank. This invention, through the design of the heat-insulating tank, can recover excess water vapor during the heating and concentration process inside the concentration tank, and then use this vapor to heat the inside of the storage tank, thus making the device more energy-efficient and avoiding resource waste.

[0004] The above solution, which uses heating and water vapor recovery, can improve work efficiency to a certain extent. However, when applied to corn protein solutions, the heating coil has a low adjustable temperature, which affects work efficiency.

[0005] Currently, corn gluten concentration equipment suffers from low operating efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the technical problem of low working efficiency in existing corn protein concentration devices, and to provide a concentration device for corn gluten fermentation extraction and enzymatic hydrolysis of corn protein, thereby overcoming the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A concentration device for extracting enzymatically hydrolyzed corn protein by fermentation of corn steep liquor includes a concentration tank; an aeration disc is provided at the bottom of the concentration tank; a negative pressure pipe is provided at the top of the concentration tank; the aeration disc extends out of the concentration tank through a main pipe and is equipped with a corresponding heating box, a filter box and a blower; a horizontally distributed mesh plate is provided at the top of the concentration tank, and the four sides of the mesh plate are connected to the inner wall of the concentration tank; multiple movable small balls are provided on the mesh plate.

[0009] Furthermore, the aeration disc uses multiple interlocking annular tubes, which are connected and communicated through branch pipes; the aeration disc is provided with air holes around its perimeter.

[0010] Furthermore, the heating box is equipped with heating wires and a temperature controller.

[0011] Furthermore, the filter box is equipped with multiple sets of dust filter elements.

[0012] Furthermore, the aeration discs are arranged and distributed according to the shape of the bottom of the concentration tank.

[0013] This invention uses hot air contact concentration, which can quickly drive liquid evaporation and effectively solve the technical problem of low working efficiency in the prior art. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. In this description, it is obvious that the embodiments described below are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example 1, according to Figure 1-2 A concentration device for extracting enzymatically hydrolyzed corn protein from corn steep liquor fermentation includes a concentration tank 1; an aeration disc 5 is provided at the bottom of the concentration tank; a negative pressure pipe 4 is provided at the top of the concentration tank; the aeration disc extends out of the concentration tank through a main pipe 6 and is equipped with a corresponding heating box 7, a filter box 8, and a blower 9; a horizontally distributed mesh plate 3 is provided at the top of the concentration tank, and the mesh plate is connected to the inner wall of the concentration tank on all four sides; multiple movable small balls 2 are provided on the mesh plate.

[0019] The aeration disc 5 is made of multiple interlocking annular tubes, which are connected and communicated through branch pipes 11; the aeration disc is provided with air holes 10 around its perimeter.

[0020] The heating box 7 is equipped with heating wires and a temperature controller.

[0021] The filter box 8 is equipped with multiple dust filter elements.

[0022] When in use, the solution is transported to the concentration tank 1, and then the blower 9 and the heating box 7 are turned on. The clean airflow enters the aeration plate and then emerges in the form of bubbles. It is then discharged through the negative pressure pipe 4. When the bubbles stack up, they are further raised by being crushed by the screen and small balls.

[0023] The heating box 7 controls the liquid temperature in the concentration tank 1 to within 70 degrees Celsius, which does not affect the protein structure. Compared with stirring evaporation, vacuum evaporation, etc., the efficiency of this application is greatly improved.

[0024] In Example 2, the aeration discs 5 are arranged and distributed according to the shape of the bottom of the concentration tank.

[0025] The bottom of the concentration tank is arc-shaped and tapered, and the aeration disc has more than 5 interlocking annular pipes distributed in a stepped manner.

[0026] In Example 3, a condenser is installed on the negative pressure pipe 4 to collect water and connect it to the fan for circulation, thereby maintaining the cleanliness of the airflow and reducing solution contamination.

[0027] For some common structures of the concentration tank, such as the inlet and outlet, they will not be marked or described in detail. For common mechanical connection methods and electrical components, such as the working methods of the fan and heating wire, they will not be described in detail.

[0028] This invention utilizes hot air contact concentration, which can rapidly drive liquid evaporation, effectively solving the technical problem of low work efficiency in existing technologies.

Those skilled in the art should understand that, and this should be clear to those skilled in the art, all modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection of this utility model.
