DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0039] The full-range stirring structure 7 includes a stirring rod 71 fixedly mounted on the bottom end of the output shaft of the driving motor 4 and the stirring rod 71 passes through the cover plate 6. A positioning ring 72 is rotatably connected to the outer side of the stirring rod 71. A rotating ring 73 is rotatably connected to the outer side of the positioning ring 72. A circular ring 78 is rotatably connected to the bottom end of the rotating ring 73. A rotating sleeve 79 is fixedly mounted on the bottom end of the circular ring 78. A connecting rod 718 is welded between the bottom end of the inner wall of the rotating sleeve 79 and the bottom end of the outer side of the stirring rod 71. A first electric telescopic rod 710 is symmetrically embedded and installed at the bottom end of the rotating ring 73. A movable connecting rod 718 is movably connected to the stirring rod 710 and is clamped and installed at the bottom end of the first electric telescopic rod 710. An inner ring 711 is arranged on the outside of the inner ring 71, and a middle ring 712 is rotatably connected to the outer side of the inner ring 711, and an outer ring 713 is rotatably connected to the outer side of the middle ring 712. The bottom end of the rotating ring 73 is located between the two first electric telescopic rods 710, and two second electric telescopic rods 714 are installed thereon, and the fixed ends of the second electric telescopic rods 714 pass through the middle ring 712. An inner ring 715 is clamped and installed on the movable ends of the second electric telescopic rods 714. The outer side of the inner ring 715 is rotatably connected to an outer ring 716 movably connected to the outer side of the stirring rod 71, and a plurality of memory metal sheets 717 are equidistantly welded between the outer ring 716 and the outer ring 713.

[0040] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the outer side of the rotating sleeve 79 is provided with matching grooves at equal intervals, and the memory metal sheet 717 is located inside the matching grooves. The shape of the memory metal sheet 717 is arc-shaped, which can facilitate the placement of the memory metal sheet 717.

[0041] like Figure 6 and Figure 5 As shown, the top edges of the inner ring 711, the middle ring 712, the outer ring 713, the inner ring 715 and the outer ring 716 are provided with inclined angles, the tops of the inner ring 711, the middle ring 712 and the outer ring 713 are combined into an inclined surface, and the tops of the inner ring 715 and the outer ring 716 are combined into an inclined surface;

[0042] By guiding objects at the edge of the inclined surface, objects are prevented from remaining on the inner ring 711, the middle ring 712, the outer ring 713, the inner ring 715 and the outer ring 716, thereby facilitating the collection and removal of subsequent objects.

[0043] like Figure 3 and Figure 4 As shown, the top of the rotating ring 73 is equidistantly embedded with a clamping joint 74, and a fixing ring 77 is sleeved between the tops of the plurality of clamping joints 74, and the fixing ring 77 is fixedly installed at the bottom end of the cover plate 6;

[0044] The installation between the rotating ring 73 and the cover plate 6 can be facilitated, the installation difficulty between the cover plate 6 and the rotating ring 73 can be changed, and the positioning between the cover plate 6 and the rotating ring 73 can be facilitated.

[0045] like Figure 3 and Fig. 9 As shown, spring rods 75 are symmetrically embedded in the clamp joint 74, and an extrusion strip 76 is clamped and installed between one end of the two spring rods 75. The top edge of the extrusion strip 76 is rounded. The top of the clamp joint 74 is conical, and the bottom of the clamp joint 74 is cylindrical.

[0046] It is convenient to increase the squeezing force between the rotating ring 73 and the cover plate 6, prevent the rotating ring 73 and the cover plate 6 from shaking with each other, and further increase the stability of the rotating ring 73 and the cover plate 6 after connection.

[0047] like Figure 5 and Fig. 9 As shown, a blade 720 is installed on the outside of the stirring rod 71 at a position inside the rotating ring 73, a plurality of connecting holes 719 are equidistantly provided inside the stirring rod 71 and the rotating ring 73, and an air outlet is provided in the connecting hole 719 located inside the stirring rod 71 for exhausting gas, and an air inlet is equidistantly provided on the outside of the rotating sleeve 79;

[0048] In addition, air inlets are equidistantly provided on the outside of the rotating sleeve 79 to form an air inlet channel. When the stirring rod 71 rotates, the blades 720 are driven to rotate. When the blades 720 rotate, the gas is driven to flow along the inside of the multiple connecting holes 719, and the rice is bubbled and stirred by the flowing gas.

[0049] like Figure 5 and Figure 8 As shown, a fixing plug 721 is clamped and installed at the bottom end of the stirring rod 71 at an inner position of the connecting hole 719, and a conical hole is opened inside the fixing plug 721, and the top diameter of the conical hole is larger than the bottom diameter.

[0050] It is convenient to block the gas without hindering the flow of the gas, so that the gas flows along different positions inside the connecting hole 719, thereby generating bubbles inside the immersion tank 3.

[0051] like Figure 1 and Figure 2 As shown, a circular hole is formed at the top of the cover plate 6, and the bottom end of the telescopic column 5 is located inside the circular hole;

[0052] The installation between the telescopic column 5 and the cover plate 6 is facilitated, and the installation difficulty between the cover plate 6 and the telescopic column 5 is changed, thereby preventing the cover plate 6 from rotating.

[0053] A processing technology for extracting rice protein from rice comprises the following steps:

[0054] Raw material preparation: select high-quality rice, wash and remove impurities, and soak it in clean water in the soaking tank 3 for 4-6 hours to increase the moisture content of the rice, and stir it through the full-range stirring structure 7;

[0055] Raw material preparation: grind the soaked rice into particles of 100-200 meshes to increase the surface area of ​​the rice for subsequent extraction;

[0056] Raw material extraction: Mix the crushed rice and water in a certain proportion (e.g., 1:10), extract the protein by enzymatic method, select enzyme (protease) to react under suitable temperature and pH conditions, and the reaction time is 1-2 hours;

[0057] Raw material separation: The extract and the solid residue are separated by centrifugation, and the supernatant is collected. At this time, the supernatant contains rice protein and other soluble components.

[0058] Concentration: The supernatant is concentrated to remove small molecules to obtain a concentrated rice protein solution.

[0059] Drying: The concentrated protein solution is spray dried or freeze dried to obtain rice protein powder. The temperature is controlled during the drying process to maintain the activity and nutritional components of the protein.

[0060] Working principle: During the actual use of the device, the rice is put into the soaking tank 3, and then the cover plate 6 is installed. At this time, the cover plate 6 enters the fixing ring 77 and enters the outside of the clamping joint 74, and at the same time, the tension of the spring rod 75 drives the extrusion strip 76 and the inner wall of the fixing ring 77 to fit together, and then the telescopic column 5 is pulled, and the movable end of the telescopic column 5 enters the circular hole at the top of the cover plate 6, thereby completing the fixing of the position of the cover plate 6, further achieving the purpose of fixing the rotating ring 73, changing the difficulty of fixing the rotating ring 73, thereby facilitating the operation of the stirring structure inside the full-range stirring structure 7, and further facilitating the stirring of the objects inside the soaking tank 3;

[0061] Then, the driving motor 4 is started. When the driving motor 4 is running, it drives the stirring rod 71 to rotate. When the stirring rod 71 rotates, it drives the rotating sleeve 79 to rotate through the connecting rod 718. When the rotating sleeve 79 rotates, it drives the memory metal sheet 717 to rotate. When the memory metal sheet 717 rotates, it drives the outer ring 713 to rotate around the middle ring 712 and the outer ring 716 to rotate around the inner ring 715. When the memory metal sheet 717 rotates, the rice inside the soaking tank 3 is stirred. Then, when the first electric telescopic rod 710 is running, it drives the inner ring 711 to descend. At this time, the inner ring 711 drives the outer ring 713 to descend through the middle ring 712. At this time, when the second electric telescopic rod 714 is not running, the memory metal sheet 717 is squeezed from top to bottom and enters the bottom of the soaking tank 3. At the same time, the stirring range is expanded. Similarly, when the second electric telescopic rod 714 is running, it drives the inner ring 715 to rise. When the inner ring 715 rises, it drives the outer ring 716 to rise. At this time, the first electric telescopic rod When 710 is not in operation, the memory metal sheet 717 is squeezed upward from the bottom and enters the top of the soaking tank 3, and the stirring range is expanded. Then, when the first electric telescopic rod 710 and the second electric telescopic rod 714 are synchronously operated, the upper and lower ends of the memory metal sheet 717 are synchronously pressed together, so that the memory metal sheet 717 is expanded from the middle to the outside, and then the middle of the soaking tank 3 is stirred, which can ensure that the water in the rice is uniformly penetrated into each grain of rice during the soaking process, avoid insufficient or excessive water absorption of some rice, and prevent the rice from settling at the bottom of the tank, ensuring that all rice can fully contact the water. The uniform water penetration and good rice state are conducive to the subsequent protein extraction, improve the quality and yield of the final product, and accelerate the water penetration speed, thereby shortening the soaking time, improving the overall process efficiency, and preventing the adhesion between rice grains, keeping the rice in a loose state, which is convenient for subsequent processing and extraction;

[0062] When the stirring rod 71 rotates, the blade 720 is driven to rotate. When the blade 720 rotates, the gas is driven to enter the connecting hole 719 along the air inlet of the rotating ring 73, and enters the soaking tank 3 along the air outlet at the edge of the connecting hole 719 under the action of the blocking of the fixed plug 721, so that bubbles are formed in the soaking tank 3 for stirring, and the material is prevented from accumulating on the outside of the stirring rod 71, so as to facilitate the subsequent removal of the rice.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
