Description

Technical Field

[0001] The present application relates to the technical field of tomato processing, and in particular to a tomato skin and seed separation device. Background Art

[0002] In the tomato paste production process, the tomato fruit and its juice undergo a fine pulping and crushing process in a pulper, followed by centrifugation. This process effectively separates the tomato juice from the peel and seeds. The separated tomato juice is then transported to an evaporation system for further processing, such as concentration; the tomato skins and seeds are discharged from the pulper's outlet as residue. Under the current production model, tomato seeds and skins are not fully developed and utilized. For example, the unsaturated fatty acids and vitamin E in tomato seeds, as well as the vitamin C and lycopene in tomato skins, are not effectively extracted. This results in the by-product value generated during tomato processing not being fully tapped and effectively converted into concrete economic benefits. Summary of the Invention

[0040] The following will clearly and completely describe the technical solutions of this application in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The following combination Figures 1-6 , describing the tomato skin and seed separation device provided in the embodiments of the present application.

[0042] Reference Figure 1 As shown, the present embodiment provides a tomato skin and seed separation device comprising a mixing tank 200, a circulating water tank 600, a separation tank 300, and a salvaging assembly 400. The mixing tank 200 is connected to the slag outlet of a pulper 100. Specifically, during the production and processing of ketchup, the tomato fruits are pulped and crushed by the pulper 100. The pulped tomato juice is separated and transported to an evaporation system for further processing such as concentration. The tomato skins and seeds are discharged from the slag outlet of the pulper 100 and fall into a screw conveyor, which then transports them to the mixing tank 200.

[0043] The circulating water tank 600 is connected to the water inlet of the mixing tank 200 and is used to inject water into the mixing tank 200 to disperse the tomato skins and seeds in the water. Specifically, a stirring shaft is installed in the mixing tank 200, and the stirring shaft is used to disperse the tomato skins and seeds in the water. In some embodiments, an aeration tube is installed at the bottom of the mixing tank 200, with aeration holes spaced apart. The outer end of the aeration tube is connected to a blower, which blows air into the mixing tank 200 through the aeration holes, thereby facilitating the dispersion of the tomato skins and seeds in the water.

[0044] The separation tank 300 is connected to the discharge port of the mixing tank 200. The separation tank 300 separates the tomato skins and seeds into layers by generating a vortex. Specifically, a feed channel is provided on the sidewall of the separation tank 300, and the feed channel is arranged tangentially to the separation tank 300. In this way, water containing the tomato skins and seeds flows into the separation tank 300 tangentially through the feed channel, thereby forming a fixed vortex in the separation tank 300. Due to the significant difference in density and size between the tomato skins and tomato seeds, the vortex gradually separates the tomato skins and tomato seeds into distinct layers within the separation tank 300. The tomato skins, due to their relatively light weight, slowly float to the upper region of the separation tank 300, while the tomato seeds, due to their greater density, gradually settle to the bottom of the separation tank 300.

[0045] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the salvage assembly 400 is used to salvage tomato peels from the upper layer of the separation tank 300. In some specific embodiments, the salvage assembly 400 includes a hollow cylinder 410, a central rod 420, branch rods 430, and a filter 440. Rotating seats 450 are spaced apart along the circumference of the lower end of the hollow cylinder 410. The rotating seats 450 are mounted to the lower end of the hollow cylinder 410 via a rotating shaft. The rotating seats 450 can rotate about the horizontal rotating shaft to achieve upside-down rotation. The rotating seats 450 are formed with cylindrical grooves 451. Each cylindrical groove 451 is slidably mounted with a branch rod 430. The branch rods 430 can slide axially along the cylindrical groove 451. The cylindrical grooves 451 have openings formed in their sidewalls. Portions of the sidewalls of the branch rods 430 are positioned outside the openings and are spaced apart with hanging rings. The filter 440 is secured to the hanging rings via ties. The center rod 420 is disposed within the hollow cylinder 410, and the lower end of the center rod 420 is rotatably connected to the upper ends of the branch rods 430 via a pin. When the center rod 420 moves downwardly along the axial direction of the hollow cylinder 410, it drives each branch rod 430 to slide downwardly along the axial direction of the corresponding cylindrical slot 451, and each branch rod 430 diverges in all directions, thereby extending the filter 440 below the hollow cylinder 410. When the center rod 420 moves upwardly along the axial direction of the hollow cylinder 410, it drives each branch rod 430 to slide upwardly along the axial direction of the corresponding cylindrical slot 451, and each branch rod 430 converges toward the center, thereby shrinking the filter 440 into the hollow cylinder 410.

[0046] The salvage assembly 400 also includes a support platform 460, a first lifting module 470, a movable base 480, and a second lifting module 490. The support platform 460 is rotatably mounted on a fixed frame via a central axis 461. The central axis 461 is connected to the output end of a motor via a pulley and a belt, and the motor can drive the support platform 460 to rotate around the central axis 461. The first lifting module 470 is disposed on the support platform 460, and the movable base 480 is connected to the slider of the first lifting module 470. The hollow cylinder 410 is fixed to the movable base 480. The first lifting module 470 can drive the movable base 480 to move up and down as a whole, thereby achieving the lifting of the hollow cylinder 410. The second lifting module 490 is mounted on the movable base 480. The slider of the second lifting module 490 is connected to the upper end of the center rod 420. The second lifting module 490 can drive the center rod 420 to move up and down within the hollow cylinder 410.

[0047] Reference Figure 4 As shown, a blocking brush 500 is provided at the lower end of the hollow cylinder 410 . When the filter screen 440 is retracted into the hollow cylinder 410 , the blocking brush 500 is used to brush off the tomato skins on the filter screen 440 .

[0048] In some embodiments, the tomato skin and seed separation device further includes an enzyme injector 700. The outlet of the enzyme injector 700 is connected to the mixing tank 200 and is used to inject enzymes, such as pectinase, into the mixing tank 200 to pre-treat the tomato skins and seeds. Pectinase can break down the pectin in the tomato cell walls, weakening the bond between the tomato pulp and the skin and seeds, thereby facilitating separation of the pulp from the skin and seeds. This prevents excessive pulp from adhering to the tomato skin, which would otherwise weigh the tomato down, facilitating subsequent separation.

[0049] In some embodiments, the tomato skin and seed separation device further includes a first dewatering screen 800, a second dewatering screen 900, and an induced draft fan. The inlet of the first dewatering screen 800 is connected to the outlet of the separation tank 300. Tomato seeds flowing out of the outlet of the separation tank 300 enter the first dewatering screen 800 for dehydration. The salvaging assembly 400 can shake the salvaged tomato skins onto the second dewatering screen 900 for dehydration. The outlets of the first and second dewatering screens 800 and 900 are respectively connected to the circulating water tank 600, and the dewatered water continues to flow back into the circulating water tank 600. The induced draft fan is used to introduce low-temperature drying air into the first and second dewatering screens 800 and 900. Low-temperature air drying prevents the oxidation and deterioration of nutrients such as unsaturated fatty acids and vitamin E in the tomato seeds at high temperatures, and prevents the loss of vitamin C and lycopene in the tomato skins at high temperatures.

[0050] The workflow of this application:

[0051] The tomato skins and seeds discharged from the pulping machine 100 enter the mixing tank 200, where water is introduced according to a specific ratio to uniformly mix the tomato skins and seeds with the water. Continuous stirring is performed by mechanical force, allowing the tomato seeds and skins, which were originally adhered to each other, to be fully dispersed in the water to form a mixed material.

[0052] The mixed material is conveyed into the separation tank 300 by a screw pump, where a fixed vortex is formed. Due to the significant difference in density and size between the tomato skins and tomato seeds, the vortex gradually separates the tomato skins and tomato seeds into distinct layers within the separation tank 300. The tomato skins, being relatively light, slowly float to the upper area of ​​the separation tank 300, while the tomato seeds, due to their higher density, gradually sink to the bottom of the separation tank 300.

[0053] The second lifting module 490 moves, driving the central rod 420 to move downward along the axial direction of the hollow cylinder 410, driving each branch rod 430 to slide downward along the axial direction of the corresponding cylindrical groove 451. Each branch rod 430 diverges in all directions, thereby expanding the filter screen 440.

[0054] The first lifting module 470 moves upward, driving the movable base 480 and the hollow cylinder 410 on the movable base 480 to move upward as a whole, and the tomato skin is fished out by the stretched filter 440;

[0055] The supporting platform 460 rotates around the central axis 461, driving the movable base 480 and the hollow cylinder 410 on the movable base 480 to move as a whole to above the second dewatering screen 900;

[0056] The second lifting module 490 moves upward along the axis of the hollow cylinder 410, driving the central rod 420 to slide upward along the axis of the corresponding cylindrical slot 451. The branch rods 430 converge toward the center, thereby tightening the filter 440. At the same time, the blocking brush 500 at the lower end of the hollow cylinder 410 brushes the tomato peels on the filter 440 down to the entrance of the second dehydration screen 900, so that they can reach the second dehydration screen 900 smoothly.

[0057] The tomato seeds and water at the bottom of the separation tank 300 enter the first dewatering screen 800 .

[0058] The induced draft fan introduces low-temperature drying gas into the first dehydration screen 800 and the second dehydration screen 900 respectively, so that the tomato seeds and tomato skins are air-dried at low temperature in the first dehydration screen 800 and the second dehydration screen 900 and then discharged to the corresponding temporary storage bin through the screw conveying pump.
