[0002] Raw material mixing is a key step in dairy production. Before dairy production, rennet needs to be added to form curd. The curd is then cut into curd particles by a dairy raw material mixing device. The mixing device further stirs the curd particles to separate the whey in the curd particles, causing the curd particles to shrink and become firmer, until the curd particles reach the ideal texture.

[0003] The existing dairy product raw material mixing device includes a horizontal knife assembly and a vertical knife assembly. The horizontal knife assembly has multiple horizontal blades, and the vertical knife assembly has multiple vertical blades. The horizontal knife assembly and the vertical knife assembly are moved in the raw material tank to cut the curd and stir it. However, the blade density of the existing horizontal knife assembly and the vertical knife assembly cannot be adjusted, and only curd particles of a fixed size can be cut. Since curd particles of different sizes are required when producing different types of dairy products or adjusting the production process, blades of different densities need to be customized, which reduces the efficiency of dairy product production.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment 1: The present invention provides a technical solution: a raw material mixing device for dairy product production, such as Figure 1 As shown, it includes a raw material tank 101, a bracket 102 is fixed on the raw material tank 101, a double-shaft stirring mechanism 400 is arranged under the bracket 102, a horizontal knife assembly 200 is installed on one output shaft 401 of the double-shaft stirring mechanism 400, and a vertical knife assembly 300 is installed on the other output shaft 401.

[0022] like Figure 1 、 2 As shown, the vertical knife assembly 300 includes a vertical knife seat 301, which is detachably fixed under the output shaft 401. A plurality of vertical support rods 302 are detachably provided under the vertical knife seat 301, and the vertical support rods 302 are used to cut curd particles.

[0023] like Figure 1 、 3As shown in Figure 4, the cross-knife assembly 200 includes a cross-knife seat 201, which is detachably fixed to the output shaft 401. The vertical branch of the L-shaped rod 202 is fixed under the cross-knife seat 201. The lower end of the transverse rod 203 is slidably provided on the transverse branch of the L-shaped rod 202. The upper end of the transverse rod 203 is fixed under the slider 204. The slider 204 is threadedly connected to the screw 205. The screw 205 is rotatably provided on the cross-knife seat 201. The screw 205 is coaxially fixed with a worm 206, and the worm 206 is meshed with the worm gear 206. 10. The worm gear 210 is rotatably arranged on the cross-knife seat 201. A wire reel 207 is coaxially fixed to the worm gear 210. One end of a rope 208 is fixed to the wire reel 207. A pin 209 is fixed at the corner of the L-shaped rod 202. The other end of the rope 208 is passed around the pin 209 and fixed to the transverse rod 203. A transverse support rod 211 is detachably arranged between the L-shaped rod 202 and the transverse rod 203. The transverse support rod 211 is used to cut curd particles. The transverse rod 203 can press the transverse support rod 211 onto the L-shaped rod 202.

[0024] The vertical support rods 302 are detachably fixed under the vertical knife seat 301. By adjusting the number of vertical support rods 302, the density of the cutting parts (i.e., the vertical support rods 302) of the vertical knife assembly 300 used to perform the cutting action can be adjusted. At the same time, the detachable connection method facilitates the cleaning of the vertical support rods 302. The horizontal support rods 211 are clamped under the horizontal knife seat 201 by the L-shaped rods 202 and the transverse rods 203. By adjusting the number of transverse support rods 211, the density of the cutting parts (i.e., the transverse support rods 211) of the transverse knife assembly 200 used to perform the cutting action can be adjusted. At the same time, the detachable connection method facilitates the cleaning of the transverse support rods 211. Since the density of the vertical support rods 302 and the transverse support rods 211 can be adjusted, it is convenient to cut curd particles of different sizes according to production conditions, thereby improving production efficiency.

[0025] The upper end of the transverse rod 203 is fixed on the slider 204, and the slider 204 is driven by the screw 205. By rotating the screw 205, the slider 204 is moved, and then the upper end of the transverse rod 203 is moved, and then the transverse support rod 211 is clamped. One end of the rope 208 is fixed to the bottom end of the transverse rod 203, and the other end of the rope 208 is fixed to the winding drum 207. By rotating the winding drum 207 to tighten the rope 208, the lower end of the transverse rod 203 is moved, and then the transverse support rod 211 is further clamped. By moving the upper end and the lower end of the transverse rod 203, the transverse support rod 211 can be fully clamped, making the cross-blade assembly 200 more stable.

[0026] The cable reel 207 is fixed on the worm gear 210, and the worm gear 210 is driven by the worm 206. The worm 206 is fixed on the lead screw 205. The rotation of the lead screw 205 drives the worm 206 to rotate and then drives the worm gear 210 to rotate, and then drives the cable reel 207 to rotate. The rotation of the lead screw 205 can drive the slider 204 to move. Through the above structure, the rotation of the lead screw 205 can drive the cable reel 207 to rotate, and then synchronously move the upper and lower ends of the transverse rod 203 to facilitate clamping the transverse support rod 211.

[0027] In order to facilitate the disassembly of the horizontal knife seat 201 or the vertical knife seat 301, Figure 2 、 3 As shown, a connecting plate 103 is fixed under each output shaft 401, two screws 104 are fixed under the connecting plate 103, and mounting seats 105 are respectively fixed on the vertical knife seat 301 and the horizontal knife seat 201. Each mounting seat 105 has two through holes, and the screw 104 can be inserted into the corresponding through holes of the mounting seat 105. The screw 104 is threadedly connected to a nut 106 at a position below the mounting seat 105.

[0028] In order to facilitate the removal of the vertical support rod 302, as shown in FIG. Figure 2 As shown, a plurality of mounting holes 303 are provided on the vertical knife seat 301 , and a vertical support rod 302 is slidably provided in the mounting hole 303 . One end of the vertical support rod 302 can be inserted into the raw material tank 101 , and a blocking piece 304 is fixed to the other end.

[0029] When installing the vertical support rod 302, after inserting the vertical support rod 302 into the mounting hole 303, the vertical support rod 302 descends under the action of its own weight until the blocking piece 304 presses the vertical knife seat 301, and the vertical support rod 302 is installed on the vertical knife seat 301. When removing the vertical support rod 302, it is only necessary to pull the vertical support rod 302 upward from the mounting hole 303.

[0030] like Figure 3 、 4 As shown, two winding drums 207 are symmetrically fixed on the worm gear 210, and two pins 209 are symmetrically fixed at the corners of the L-shaped rod 202. One end of the rope 208 is fixed to one winding drum 207, and the other end is wrapped around a pin 209 and wound around the transverse rod 203, and then wrapped around another pin 209, and finally fixed to the other winding drum 207.

[0031] The rotation of the worm gear 210 can drive the two winding drums 207 to rotate at the same time, thereby driving the rope 208 to be tightened on the winding drum 207, and then driving the transverse rod 203 wrapped with the rope 208 to move. Since the rope 208 drives the transverse rod 203 to move by being wound on the transverse rod 203, the part of the rope 208 in the raw material tank 101 is connected to the transverse rod 203 in a simple way, and there is no need to add additional structure to the transverse rod 203, thereby reducing sanitary dead corners.

[0032] In order to reduce sanitary blind spots, the L-shaped rod 202 has a circular cross section.

[0033] In order to reduce sanitary blind spots, the cross section of the transverse rod 203 is circular, and a ring is fixed to the bottom end of the transverse rod 203 , which is slidably arranged on the horizontal branch of the L-shaped rod 202 .

[0034] In order to make the cross rod 211 more stably clamped by the L-shaped rod 202 and the traverse rod 203, as shown in FIG. Figure 3 As shown, the horizontal support rod 211 is blade-shaped, and semicircular notches are opened at both ends of the horizontal support rod 211. The semicircular notches can be stuck on the vertical support of the transverse rod 203 or the L-shaped rod 202.

[0035] In order to facilitate the rotation of the lead screw 205, as Figure 4 As shown, a hexagonal head 212 is fixed on the lead screw 205 , and the hexagonal head 212 can be adapted to a wrench. The hexagonal head 212 can be rotated using the wrench, thereby rotating the lead screw 205 .

[0036] like Figure 1 、 5 As shown, the double-output shaft stirring mechanism 400 includes a main motor 405, which is fixed on the bracket 102, and a rotating box 402 is fixed to the output end of the main motor 405. Two output shafts 401 are arranged to rotate under the rotating box 402. One output shaft 401 is driven by a sub-motor 406, and the sub-motor 406 is fixed on the rotating box 402. Since the rotating box 402 can rotate infinitely and thus drive the sub-motor 406 thereon to rotate infinitely, an electric slip ring 407 is used in this embodiment to transmit power to the sub-motor 406. The electric slip ring 407 is installed under the bracket 102. The power transmission of the electric slip ring 407 belongs to the existing technology and will not be described in detail. The other output shaft 401 is driven by a driven pulley 403, which is rotatably arranged in the rotating box 402. A driving pulley 404 is fixed to the output end of the sub-motor 406. The driving pulley 404 is rotatably arranged in the rotating box 402, and the driving pulley 404 is connected to the driven pulley 403 by a belt.

[0037] The main motor 405 can drive the rotating box 402 to rotate, and then drive the output shaft 401 to revolve. The sub-motor 406 can directly drive one output shaft 401 to rotate, and can also drive the active pulley 404 to rotate, and then drive the driven pulley 403 to rotate through the belt, and then drive the other output shaft 401 to rotate. The rotation of the output shaft 401 can drive the horizontal knife assembly 200 and the vertical knife assembly 300 to rotate. The horizontal knife assembly 200 can cut the curd horizontally, and the vertical knife assembly 300 can cut the curd vertically. The cooperation of the horizontal knife assembly 200 and the vertical knife assembly 300 can fully cut the curd and stir it.

[0038] Working process: When adjusting the density of the cross-blade assembly 200, first remove the cross-blade seat 201 from the output shaft 401, and then loosen the cross-blade assembly 200. During the loosening process, the slider 204 is driven to move by rotating the screw 205, and then the transverse rod 203 is driven to move, thereby increasing the distance between the transverse rod 203 and the vertical branch of the L-shaped rod 202. The rotation of the screw 205 can drive the worm 206 to rotate, and then drive the worm wheel 210 to rotate, and then drive the winding drum 207 to rotate, and then loosen the rope 208, so that the transverse rod 203 no longer presses the transverse support rod 211, and completes the work of loosening the cross-blade assembly 200.

[0039] After completing the work of loosening the cross blade assembly 200 , the density of the cross bars 211 of the cross blade assembly 200 is reduced by increasing the number of cross bars 211 , and the density of the cross bars 211 of the cross blade assembly 200 is increased by reducing the number of cross bars 211 .

[0040] Subsequently, the reversing screw 205 drives the slider 204 to move in the opposite direction, and then drives the transverse rod 203 to move in the opposite direction, thereby reducing the distance between the transverse rod 203 and the vertical branch of the L-shaped rod 202. The reversal of the screw 205 can drive the worm 206 to reverse, and then drive the worm wheel 210 to reverse, and then drive the winding reel 207 to reverse, and then tighten the rope 208, so that the transverse rod 203 presses the transverse support rod 211, completing the density adjustment work of the transverse knife assembly 200, and then the transverse knife seat 201 is installed back on the output shaft 401.

[0041] When adjusting the density of the vertical knife assembly 300, first remove the vertical knife seat 301 from the output shaft 401, and then reduce the density of the vertical support rods 302 of the vertical knife assembly 300 by increasing the number of vertical support rods 302, and increase the number of vertical support rods 302 by inserting the vertical support rods 302 into the mounting holes 303 of the vertical knife seat 301, and increase the density of the vertical support rods 302 of the vertical knife assembly 300 by reducing the number of vertical support rods 302, and reduce the number of vertical support rods 302 by pulling the vertical support rods 302 out of the mounting holes 303 of the vertical knife seat 301. After completing the density adjustment of the vertical knife assembly 300, install the vertical knife seat 301 back on the output shaft 401.

[0042] Embodiment 2: Another aspect of the present invention provides a mixing process using a raw material mixing device for dairy product production according to the embodiment, comprising the following steps: S1. Adjustment: Adjust the number of horizontal support rods 211 of the horizontal blade assembly 200 and the number of vertical support rods 302 of the vertical blade assembly 300 according to the working conditions; S2, prepare, install the horizontal blade assembly 200 and the vertical blade assembly 300 respectively on the output shaft 401 of the double-output shaft stirring mechanism 400; S3, stirring, starting the double-shaft stirring mechanism 400 to stir the dairy product in the raw material tank 101; S4, cleaning, remove the horizontal knife assembly 200 and the vertical knife assembly 300 for cleaning.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
