DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below through specific embodiments in combination with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention in any way. The accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding and are not intended to limit the present invention in any way.

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0033] As mentioned in the background art, oatmeal bases are often removed during production due to the rough texture of the solid matter after grinding, especially after sterilization, which easily reacts with protein to form flocculation. These solid matter contains a large amount of dietary fiber and protein, resulting in low dietary fiber content in existing oatmeal drinks.

[0034] For the reasons mentioned above, please refer to the attached Figure 1 -Attached Figure 3 The present invention provides a grinding and mixing device for oat enzymolysis, comprising a mixing tank body 2, which is placed on a support 1 in a horizontal arrangement and a heating pipe 14 is provided at the bottom of the mixing tank body 2;

[0035] The grinding hopper 4 is provided on the side of the upper end of the mixing tank body 2 and is communicated with the interior of the mixing tank body 2;

[0036] The feed baffle 5 is movably arranged in the grinding hopper 4 to prevent splashing during grinding;

[0037] The stirring assembly is arranged in the mixing tank body 2 to facilitate stirring and mixing the materials inside;

[0038] The grinding roller 15 is arranged in the grinding hopper 4 to grind the material before it enters the mixing tank 2.

[0039] Please see the attached Figure 4 Specifically, an interlayer is provided at the bottom of the mixing tank body 2 , and the heating pipe 14 is arranged in the interlayer and in contact with the mixing tank body 2 .

[0040] Please see the attached Figure 7 In order to facilitate the placement of the heating pipe in the interlayer of the mixing tank body and to facilitate heating the mixing tank body, the shape of the heating pipe is an arc-shaped coil.

[0041] The ends of the heating pipes extend to the outside of the mixing tank 2 and are connected to an external heat source, such as steam or an electric heating wire.

[0042] Please see the attached Figure 4 and attached Figure 6 Specifically, the stirring assembly includes a stirring rod 11, a support rod 12 and a stirring blade 13. The stirring rod 11 is coaxially installed in the mixing tank body 2 and one end is extended to the outside of the mixing tank body 2 and connected to the driving device 9. The other end of the stirring rod 11 has a center hole. The support rod 12 is evenly arranged on the stirring rod 11 inside the mixing tank body 2 and is connected to the center hole of the support rod 12. The stirring blade 13 is spirally distributed and arranged at the outer end of the stirring rod 11 and fixed on the support rod 12.

[0043] According to the above technical features, a central hole is opened at one end of the stirring rod, and at the same time, the support rod is communicated with the central hole of the stirring rod, which is convenient for introducing gas or liquid into the mixing tank body, so as to facilitate cooling the internal oats or facilitating cleaning the inside.

[0044] Please refer to the attached Figure 2 and the attached Figure 4 . Specifically, a transmission mechanism 10 (shown as a chain transmission mechanism in the attached drawing) is provided on the stirring rod 11 outside the mixing tank body 2, and the transmission mechanism 10 is connected to the grinding roller 15 inside the grinding hopper 4.

[0045] According to the above technical features, setting the transmission mechanism can facilitate driving the stirring mechanism and the grinding roller to move synchronously through the driving device, which is convenient for stirring the internal materials and can also perform grinding at the same time.

[0046] Furthermore, the grinding rollers can be set to two and are meshed and driven by gears. Any one of the grinding rollers is connected to the transmission mechanism. A filter plate can be provided in the grinding hopper below the grinding rollers, which can effectively prevent larger oats from falling into the mixing tank body due to not participating in grinding or having larger particles after grinding, which may affect enzymatic hydrolysis.

[0047] Please refer to the attached Figure 6 . Specifically, the top of the grinding hopper 4 is cylindrical and the lower end is conical. An insertion hole is opened on the side surface of the cylindrical end of the grinding hopper 4, and the feed baffle 5 is inserted into the grinding hopper 4 from the insertion hole.

[0048] Specifically, the cross-sectional shape of the feed baffle 5 is arched. When the feed baffle 5 is inserted into the grinding hopper 4, there are gaps on both sides of it and the inner wall of the grinding hopper 4 that are convenient for material falling.

[0049] It can be seen from the attached Figure 6 that a hand-held handle is provided at one end of the feed baffle, which is convenient for pulling it out.

[0050] Please refer to the attached Figure 1 . Specifically, a removable cover plate 3 is placed on the top of the mixing tank body 2 movably.

[0051] By setting the removable cover plate, it is convenient to clean the inside.

[0052] Please refer to the attached Figure 3 . Specifically, a discharge port is opened on the side of the mixing tank body 2, and a discharge chute plate 6 is provided at the discharge port. There is a discharge baffle 7 at the discharge port. One end of the discharge baffle 7 is hinged to the top of the discharge port, and a control member 8 is rotatably provided at the other end of the discharge baffle 7. The control member 8 is threadedly connected to the discharge chute plate 6.

[0053] Specifically, the control members are a control rod and a handwheel. The control rod is threadedly connected to the discharge chute plate. When the control rod rotates on the discharge chute plate, its end will push or pull the discharge baffle to rotate around the hinge point, thereby opening or closing the discharge port.

[0054] When the mixing device grinds and enzymatically hydrolyzes oats, first, the rotation of the control member 8 drives the movement of the discharge baffle 7 to block the discharge port. Then, the drive device 9 is started to drive the grinding roller 15 and the stirring assembly to move. At the same time, the feed baffle 5 is inserted into the grinding hopper 4. Enzymes are put into the mixing tank body 2 through the opening at the top of the mixing tank body 2 or fall into the mixing tank body 2 after being put into the grinding hopper 4. Then, the cover plate 3 is placed at the opening at the top of the mixing tank body 2 to prevent the material from flying out with the rotation of the stirring assembly. Then, oats can be put into the grinding hopper 4 and fall onto the grinding roller 15 through the gap between the feed baffle 5 and the inner wall of the grinding hopper 4 under the action of gravity for grinding. The ground oat grains or oat powder enter the interior of the mixing tank body 2 to be mixed with the enzyme for an enzymatic hydrolysis reaction. During the mixing process, the internal material can be heated through the heating pipe fitting 14 to facilitate enzymatic hydrolysis. Finally, after high-temperature enzyme inactivation, cold air is introduced into the interior for cooling. Finally, the discharge baffle 7 is opened through the control member 8 to discharge, thus completing the enzymatic hydrolysis, mixing, and enzyme inactivation process of oats, effectively improving the dietary fiber of oats and reducing the sugar content.

[0055] During the enzymatic hydrolysis process, α-amylase and amylopectinase are added for the first enzymatic hydrolysis. After being treated by enzyme inactivation (high-temperature enzyme inactivation is sufficient), the temperature is lowered to 50 - 65 °C, and glucosidase is added for the second enzymatic hydrolysis. After the second enzyme inactivation, slag removal treatment (this slag removal method can adopt the existing conventional method) is carried out to obtain a high-fiber oat base material.

[0056] The above description is a detailed description of the preferred and feasible embodiments of the present invention. However, the embodiments are not used to limit the patent application scope of the present invention. Any equivalent changes or modified variations completed under the technical spirit disclosed by the present invention shall fall within the patent scope covered by the present invention.
