They belong to the flavonoid compounds and mostly exist in the form of glycosides, also known as anthocyanins. Anthocyanins, as a natural edible pigment, are widely found in a variety of fruits and vegetables. They not only give fruits and vegetables bright colors, but also play an important role in human health. Anthocyanins are widely used in the field of ice cream production. Existing fresh fruit ice cream is added with berry juices such as blackberry, raspberry, and blueberry. The remaining pomace is rich in a large amount of anthocyanins.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] The following describes an embodiment of the present invention based on its overall structure.

[0021] An extraction device for extracting anthocyanins from pomace, such as Figures 1 to 11 As shown, it includes a preliminary crushing mechanism 1, the top of which is fixedly connected to a first motor 2, the preliminary crushing mechanism 1 includes a shell 101, the first motor 2 is fixedly connected to the top of the shell 101, an upper bin body 102 is opened at the top of the inner wall of the shell 101, the bottom end of the shell 101 is connected to a sedimentation bin 111, the bottom end of the upper bin body 102 is connected to multiple groups of rolling bins 103, the inner wall of each group of rolling bins 103 is respectively sleeved with a group of rolling rollers 104, the top of each group of rolling rollers 104 is respectively fixedly connected to a group of connecting shafts 105, the top of the connecting shafts 105 extends out of the top of the shell 101, the top of each group of connecting shafts 105 is respectively slidably sleeved with a group of sliding columns 109, the tops of the multiple groups of sliding columns 109 are fixedly connected to a pulley group 110, the first motor 2 is fixedly connected to the top of the shell 101, and the upper end of the upper bin body 102 is connected to the bottom of the upper bin body 102. The output end of the machine 2 is fixedly connected to the input end of the pulley group 110, and each group of connecting shafts 105 is fixedly sleeved with a group of upper disk bodies 106 at one end outside the shell 101. The top of the shell 101 is fixedly connected to multiple groups of lower disk bodies 107, and each group of lower disk bodies 107 is rotatably sleeved on the outside of a group of connecting shafts 105. The outer walls of the upper disk body 106 and the lower disk body 107 are respectively fixedly connected with two groups of protrusions 108, and the side walls of the shell 101 are connected with two groups of feeding ports 112, and the two groups of feeding ports 112 are connected to the interior of the upper warehouse body 102. The inner wall of each group of feeding ports 112 is rotatably connected with a group of cutting blades 113, and the side walls of the feeding ports 112 are fixedly connected with a second motor 114, and the output end of the second motor 114 is fixedly connected to one end of the cutting blade 113.

[0022] The first motor 2 drives the pulley set 110, so that the pulley set 110 drives multiple sets of sliding columns 109 to rotate, so that the multiple sets of sliding columns 109 respectively drive multiple sets of connecting shafts 105 to rotate, and the connecting shaft 105 drives the rolling roller 104 to rotate during the rotation process, and drives the upper disk body 106 to rotate during the rotation of the rolling roller 104, and the upper disk body 106 drives the two sets of protrusions 108 connected thereto to rotate, and when the protrusion 108 at the bottom end of the upper disk body 106 contacts the protrusion 108 at the top end of the lower disk body 107, the upper disk body 106 is pushed and moves upward, so that the upper disk body 106 drives the connecting shaft 105 to slide upward, and the connecting shaft 105 drives the rolling roller 104 to move upward, and the protrusion 108 at the bottom end of the upper disk body 106 slides over the protrusion 108 at the top end of the lower disk body 107. At this time, under the effect of deadweight Down, the crushing roller 104 falls and resets, and drives the connecting shaft 105 and the upper disk body 106 to reset. After the pomace and the extract are placed in the feeding port 112, the cutting blade 113 is driven to rotate by the second motor 114, so that the cutting blade 113 cuts the pomace, so that the pomace is preliminarily crushed, and then the pomace falls into the upper bin body 102. In the process of the cutting blade 113 cutting the pomace, the speed at which the pomace enters the upper bin body 102 is slowed down, thereby avoiding excessive pomace from accumulating above the crushing bin 103 at one time. After the pomace enters the upper bin body 102, the pomace falls into the crushing bin 103, and then rotates and moves up and down through the crushing tube, so that the pomace is ground by the crushing roller 104, so that the pomace is crushed more thoroughly, and then the pomace falls into the filtering bin 301.

[0023] Please refer to Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The inner wall of the shell 101 is fixedly connected with a secondary crushing mechanism 3, and the secondary crushing mechanism 3 includes a filter bin 301, which is fixedly connected to the inner wall of the shell 101, and the filter bin 301 is located below the upper bin body 102, and a filter screen is arranged at the bottom end of the filter bin 301, and a first support frame 302 is rotatably connected to the bottom end of the filter bin 301, and a square hole 303 is opened at the top of the first support frame 302, and a square column 304 is slidably sleeved on the inner wall of the square hole 303, and an auger 305 is fixedly connected to the top of the square column 304, and the top of the auger 305 extends out of the shell 101, and the top of the auger 305 is connected to the first support frame 302. The output end of the motor 2 is coaxially connected, and the top of the first support frame 302 is fixedly connected to a rotating ring 306, and the inner wall of the rotating ring 306 is rotatably connected to a material transfer pipe 307, and the material transfer pipe 307 is sleeved on the outside of the auger 305. The top of the material transfer pipe 307 is connected to the upper warehouse body 102, and the internal sliding sleeve of the first support frame 302 is provided with multiple groups of side sliding frames 308, and the side walls of each group of side sliding frames 308 are respectively rotatably connected to a group of first pressure rollers 309, and the bottom end of the first support frame 302 is slidably connected to multiple groups of lower sliding frames 310, and the bottom end of each group of lower sliding frames 310 is respectively rotatably connected to a group of second pressure rollers 311.

[0024] The auger 305 is driven to rotate during the rotation of the pulley group 110, so that the auger 305 drives the square column 304 to rotate, and the square column 304 drives the first support frame 302 to rotate, so that the first support frame 302 drives the side sliding frame 308 and the lower sliding frame 310 to rotate, and the first support frame 302 drives the pomace inside the filter bin 301 to rotate during the rotation, and the pomace is made to adhere to the inner wall of the filter bin 301 under the action of centrifugal force, and the first pressing roller 309 and the second pressing roller 311 are driven to rotate by the side sliding frame 308 and the lower sliding frame 310, thereby driving the side sliding frame 308 and the lower sliding frame 310 to slide under the action of centrifugal force, so that the first pressing roller 309 and the second pressing roller 311 are close to the inner wall of the filter bin 301 and the filter screen, so that the inner wall of the filter bin 301 The pomace is crushed by the first pressing roller 309 and the second pressing roller 311, so as to further grind the pomace. Since the bottom end of the filter bin 301 is conical, the pomace will slowly gather toward the bottom inside the filter bin 301, so that the pomace passes through the filter screen. During the crushing process of the second pressing roller 311, the pomace that is fine enough passes through the filter screen, so that the pomace enters the sedimentation bin 111 and mixes with the extract. Then the pomace is precipitated at the bottom of the sedimentation bin 111. The pomace filtered by the filter screen is gathered at the bottom of the feed pipe 307. Then, through the rotation of the auger 305, the pomace moves upward from the feed pipe 307 into the loading bin under the push of the auger 305, so that the pomace enters the crushing bin 103 again and is crushed again, thereby ensuring that the pomace is broken into a sufficiently fine size and ensuring the extraction effect of anthocyanins.

[0025] Please refer to Figure 2 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 The bottom end of the filter bin 301 is fixedly connected with a slapping mechanism 4, and the slapping mechanism 4 includes a rotating column 401, which is fixedly connected to the bottom end of the first support frame 302, and the outer wall of the rotating column 401 is sleeved with a moving ring 402, and the side wall of the moving ring 402 is hinged with multiple groups of connecting rods 403, each group of connecting rods 403 is provided with a torsion spring at the contact position with the moving ring 402, and the outer wall of each group of connecting rods 403 is slidably sleeved with a group of rotating arms 404, and the end of each group of rotating arms 404 is fixedly connected with a group of rubber blocks 405, and the outer walls of the multiple groups of rotating arms 404 are hinged with a second support frame 406, and the second support frame 406 is fixedly connected to the bottom end of the filter bin 301, and the outer wall of the rotating column 401 is provided with a spiral groove 407, and a reset groove 408 is provided between the two ends of the spiral groove 407, and the inner wall of the moving ring 402 is fixedly connected with a slider 409, and the slider 409 extends to the inner wall of the reset groove 408.

[0026] The rotating column 401 is driven to rotate during the rotation of the first support frame 302. The rotating column 401 drives the spiral groove 407 and the reset groove 408 to rotate during the rotation. During the rotation of the spiral groove 407, the slider 409 slides from the bottom end of the reset groove 408 into the spiral groove 407. Then, as the spiral groove 407 rotates, the slider 409 is pushed, so that the slider 409 drives the moving ring 402 to rise. During the rising process of the moving ring 402, the connecting rod 403 drives the rotating arm 404 to flip. During this process, the connecting rod 403 twists the torsion spring. As the slider 409 slides to the end of the spiral groove 407, the slider 409 slides into the reset groove 408. At this time, the resilience of the torsion spring drives the connection to flip and reset in the opposite direction, so that the moving ring 402 is 02 descends and drives the slide groove to slide to the bottom end of the reset groove 408. The above process is repeated continuously during the continuous rotation of the rotating column 401, so that the rotating arm 404 continuously flips up and down, thereby causing the rotating arm 404 to drive the rubber block 405 to flip back and forth continuously, so that the rubber block 405 continuously beats the outer wall of the filter bin 301, causing the filter bin 301 to vibrate, so that the fruit residue inside the filter bin 301 is affected by the centrifugal force, and the fruit residue is close to the inner wall of the filter bin 301, but when the rubber block 405 hits the filter bin 301, the fruit residue on the inner wall of the filter bin 301 will gather to the bottom of the filter bin 301, preventing the fruit residue from accumulating on the inner wall of the filter bin 301 and being unable to enter the sedimentation bin 111.

[0027] When in use, the pomace and the extract are fed into the feeding port 112 so that the pomace is initially crushed by the cutting blade 113. Then, after the pomace enters the crushing bin 103, the crushing roller 104 rotates and moves up and down so that all the pomace is crushed by the crushing roller 104, thereby improving the crushing effect of the pomace. Compared with the traditional technical solution of cutting and crushing the pomace by high-speed rotation, the pomace can be ground so that the pomace can be crushed into powder, thereby ensuring the extraction effect of anthocyanins. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
