Description

Technical Field

[0001] This invention relates to the field of fruit juice processing technology, and more particularly to a dicing device for producing high-viscosity fruit juice concentrate. Background Technology

[0002] Fruit juice is a beverage made from the liquid obtained from fruits through physical methods such as pressing, centrifugation, and extraction. It retains most of the nutrients found in fruits, such as vitamins, minerals, sugars, and pectin, a type of dietary fiber. Regular consumption of fruit juice can aid digestion, promote bowel regularity, and supplement nutritional deficiencies in the diet. In the fruit juice production and processing industry, to facilitate pressing fruits into juice, the washed and peeled fruits are generally first diced or sliced.

[0003] Currently, to increase the viscosity of fruit juice, thickening powder is typically added during the pressing process, which greatly improves the taste. However, when adding thickening powder, it often only adheres to the surface of the top layer of fruit pieces inside the juicer. This results in the juice being difficult to mix evenly with the thickening powder during continuous pressing, ultimately affecting the inconsistent taste of the produced fruit juice beverage. Therefore, this application proposes a dicing device for producing high-viscosity fruit juice concentrate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dicing device for producing high-viscosity fruit juice concentrate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dicing device for producing high-viscosity fruit juice concentrate includes a processing box, a dicing plate slidably connected inside the processing box, and multiple dicing slots at the upper end of the dicing plate. Multiple powder injection grooves are also provided on the side walls of the dicing plate, with each pair of adjacent powder injection grooves positioned on either side of an adjacent dicing slot. The powder injection grooves communicate with the dicing slots via powder inlets. A powder storage tank is connected to the powder injection grooves via powder injection pipes, and an electromagnetic control valve is installed inside the powder injection pipes. The powder storage tank contains food-grade translucent thickening powder. Multiple drive grooves are provided on the side walls of the dicing plate, and an air injection mechanism for injecting air into the powder injection grooves is installed in each drive groove. The dicing plate is raised and lowered by a lifting mechanism.

[0007] Preferably, the gas injection mechanism includes a piston plate that is slidably connected in a sealed manner within the drive groove, and a one-way air inlet is provided at the top of the drive groove. The drive groove is connected to the inside of the powder injection groove through a one-way air outlet. An arc-shaped push plate is fixedly connected to the piston plate by a connecting rod. A moving mechanism that causes the arc-shaped push plate to reciprocate is installed inside the processing box.

[0008] Preferably, the moving mechanism includes two drive plates fixedly connected to the bottom of the processing box, and multiple arc-shaped protrusions are provided on the opposite side walls of the two drive plates, and the multiple arc-shaped protrusions are distributed at equal intervals along the drive plates. The piston plate is fixedly connected to the inner wall of the drive groove by a first spring vibrator.

[0009] Preferably, the lifting mechanism includes a telescopic cylinder installed on the upper end of the processing box, two top rods are fixedly connected to the upper end of the dicing plate, the upper ends of the two top rods are fixedly connected to a top plate, and the telescopic end of the telescopic cylinder is fixedly connected to the top plate.

[0010] Preferably, an arc-shaped spring sheet is fixedly connected to the inner bottom of the powder injection groove, and a second spring vibrator is also fixedly connected to the inner bottom of the powder injection groove. A striking ball is fixedly connected to the upper end of the second spring vibrator, and the natural frequency of the second spring vibrator is the same as that of the first spring vibrator.

[0011] Preferably, both the second spring oscillator and the striking ball are located inside the arc-shaped spring sheet.

[0012] Preferably, two guide rods are fixedly connected to the inner wall of the drive groove, and the guide rods slide through the piston plate in a sealed manner.

[0013] The present invention has the following beneficial effects:

[0014] 1. By setting multiple powder storage tanks on the upper side of the dicing plate and adding thickening powder into the powder injection tank through the powder injection pipe, during the process of dicing fruit in the dicing grid of the dicing plate, the air injection mechanism continuously blows the thickening powder falling into the powder injection tank onto the side wall of the diced fruit. This ensures that each diced fruit can be coated with thickening powder, and the juice produced can have a uniform taste when pressed into juice.

[0015] 2. By setting up an arc-shaped spring, a first spring oscillator, a second spring oscillator, and a striking ball, the first spring oscillator and the second spring oscillator, which have the same natural frequency, can resonate, which can force the striking ball to continuously strike the arc-shaped spring. This can bounce up some of the thickening powder that has fallen on the arc-shaped spring, so that the thickening powder can be fully utilized and waste can be avoided. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0024] Example 1:

[0025] Reference Figure 1-3 A dicing device for producing high-viscosity fruit juice concentrate includes a processing box 1, a dicing plate 3 slidably connected inside the processing box 1, and multiple dicing slots 7 opened at the upper end of the dicing plate 3. Multiple powder injection grooves 17 are also opened on the side wall of the dicing plate 3, and every two adjacent powder injection grooves 17 are arranged on both sides of adjacent dicing slots 7. The powder injection grooves 17 are connected to the dicing slots 7 through powder inlets 21. The powder injection grooves 17 are connected to a powder storage tank 18 through powder injection pipes 19, and an electromagnetic control valve is installed in the powder injection pipes 19. The powder storage tank 18 contains food-grade translucent thickening powder. Multiple drive grooves 8 are opened on the side wall of the dicing plate 3. An air injection mechanism for injecting air into the powder injection grooves 17 is installed in the drive grooves 8, and the dicing plate 3 is driven to rise and fall by a lifting mechanism.

[0026] The gas injection mechanism includes a piston plate 9 that is slidably and sealed within a drive groove 8. Two guide rods 12 are fixedly connected to the inner wall of the drive groove 8, and the guide rods 12 slidably penetrate the piston plate 9. Specifically, by setting the guide rods 12, the lateral stable movement of the piston plate 9 can be ensured.

[0027] Reference Figure 3 Furthermore, a one-way air inlet 13 is provided at the top of the inner side of the drive groove 8, and the drive groove 8 is connected to the inside of the powder injection groove 17 through a one-way air outlet 14. It should be noted that the one-way air inlet 13 only allows air to flow into the drive groove 8 from the outside of the cutting plate 3 in one direction, while the one-way air outlet 14 only allows air to flow from the inside of the drive groove 8 into the powder injection groove 17. In actual installation, one-way shut-off valves with corresponding flow directions can be installed in the one-way air inlet 13 and the one-way air outlet 14.

[0028] Piston plate 9 is fixedly connected to arc-shaped push plate 11 via connecting rod 24. A moving mechanism is installed inside processing box 1 to reciprocate the arc-shaped push plate 11. The moving mechanism includes two drive plates 22 fixedly connected to the bottom of processing box 1. Multiple arc-shaped protrusions 23 are provided on the opposite sidewalls of the two drive plates 22, and these protrusions are evenly distributed along the drive plates 22. Piston plate 9 is fixedly connected to the inner wall of drive groove 8 by a first spring vibrator 10. Specifically, by providing multiple evenly spaced arc-shaped protrusions 23 on the sidewalls of drive plates 22, when the dicing plate 3 passes through the drive plate 22 (refer to...), Figure 1 and Figure 3 The right side of the drive groove 8 is in a vertically connected state, allowing the drive plate 22 to pass through. The arc-shaped protrusion 23 periodically pushes the top arc-shaped push plate 11, thereby continuously pushing the connecting rod 24 and the piston plate 9. Under the action of the first spring oscillator 10, the piston plate 9 moves back and forth laterally.

[0029] The lifting mechanism includes a telescopic cylinder 4 mounted on the upper end of the processing box 1. Two top rods 5 are fixedly connected to the upper end of the dicing plate 3, and a top plate 6 is fixedly connected to the upper ends of the two top rods 5. The telescopic end of the telescopic cylinder 4 is fixedly connected to the top plate 6. Specifically, the telescopic cylinder 4 can drive the top plate 6 to move up and down, which in turn drives the dicing plate 3 to move up and down via the top rods 5, using the dicing slots 7 on the dicing plate 3 to dice the fruit slices.

[0030] In this invention, after the washed, peeled and sliced ​​fruit is placed into the processing box 1 through the inlet 2, the telescopic cylinder 4 is activated to drive the top plate 6 to move up and down. The top plate 6 then pushes the dicing plate 3 to move up and down synchronously through the top rod 5. The dicing grid 7 on the dicing plate 3 can cut the fruit slices into pieces of fruit cubes.

[0031] When the dicing plate 3 moves down, the electromagnetic control valve in the powder injection pipe 19 is opened for a period of time, and the thickening powder in the powder storage tank 18 can fall into the powder injection groove 17 in a certain amount. At the same time, the drive groove 8 will pass through the drive plate 22 below. Each arc-shaped protrusion 23 on the side wall of the drive plate 22 can pass through one side of the arc-shaped push plate 11 in sequence. Whenever an arc-shaped protrusion 23 contacts the arc-shaped push plate 11, it will push the arc-shaped push plate 11 to move towards the powder injection groove 17. When the arc-shaped protrusion 23 leaves the arc-shaped push plate 11, the first spring vibrator 10 can push the piston plate 9 and the connecting rod 24 to make the arc-shaped push plate 11 move back to its original position. Therefore, when the dicing plate 3 moves down and passes through the drive plate 22, the piston plate 9 can move back and forth left and right under the action of each arc-shaped protrusion 23 and the first spring vibrator 10.

[0032] by Figure 3 For example, when the piston plate 9 moves to the right, air can be drawn into the left side of the piston plate 9 through the one-way air inlet 13. When the piston plate 9 moves to the left, the drawn-in air can be blown out through the one-way air outlet 14. The airflow blown out through the one-way air outlet 14 can carry the thickening powder falling from the powder injection pipe 19 through the powder conveying port 21 and blow it into the cutting grid 7. In this way, when the thickening powder is blown onto the side walls of each layer of cut fruit pieces in the cutting grid 7, each cut fruit piece can be evenly coated with the thickening powder. Finally, when all the fruit pieces are pressed into juice, the juice squeezed from each fruit piece can be fully and evenly mixed with the thickening powder, which can greatly improve the viscosity of the juice and ensure that the juice squeezed from all the fruit pieces has a consistent taste.

[0033] Example 2:

[0034] Reference Figures 4-5 Unlike Embodiment 1, the inner bottom of the powder injection tank 17 is fixedly connected with an arc-shaped spring piece 20. It should be noted that, as... Figure 5 As shown, the curved spring 20 has a large coverage area, which allows the thickening powder that falls from the powder injection tube 19 and is not blown away by the airflow to fall above the curved spring 20.

[0035] The powder filling tank 17 also has a second spring oscillator 15 fixedly connected to its bottom, and a striking ball 16 fixedly connected to the upper end of the second spring oscillator 15. The second spring oscillator 15 has the same natural frequency as the first spring oscillator 10. Specifically, since the second spring oscillator 15 and the first spring oscillator 10 are very close, when the first spring oscillator 10 is pushed to vibrate and extend, the second spring oscillator 15 with the same natural frequency also vibrates and extends accordingly, causing the striking ball 16 to continuously strike the arc-shaped spring sheet 20, so as to bounce up the thickening powder falling on the arc-shaped spring sheet 20. Furthermore, the striking ball 16 can be made into a hollow structure to reduce the weight of the striking ball 16, thereby reducing the vibration resistance of the second spring oscillator 15. Both the second spring oscillator 15 and the striking ball 16 are located inside the arc-shaped spring sheet 20.

[0036] As can be seen from Embodiment 1, when the dicing plate 3 moves downward, the piston plate 9, connecting rod 24, and arc-shaped push plate 11 in the drive groove 8 will reciprocate left and right. Correspondingly, the first spring oscillator 10 will also continuously extend and retract, vibrating in the horizontal direction. Since the second spring oscillator 15 has the same natural frequency as the first spring oscillator 10, referring to... Figure 5 Furthermore, the first spring oscillator 10 and the second spring oscillator 15 are very close together, so the second spring oscillator 15 can resonate synchronously and extend and retract vertically. This causes the striking ball 16 above the second spring oscillator 15 to move up and down continuously. The striking ball 16 will continuously strike the arc-shaped spring 20 above. Some of the thickening powder falling from the powder injection tube 19 will not be blown to the side wall of the fruit pieces by the airflow, but will fall onto the arc-shaped spring 20. When the striking ball 16 continuously strikes the arc-shaped spring 20, the thickening powder that has fallen onto the arc-shaped spring 20 can be bounced up again and blown onto the surface of the fruit pieces by the airflow. On the one hand, the fallen thickening powder can be fully utilized to avoid waste; on the other hand, it can also ensure that each layer of cut fruit pieces is fully coated with thickening powder, ensuring that the pressed juice has a good viscous texture.

[0037] It is also worth mentioning that when the dicing plate 3 is moved upward and reset, the drive groove 8 will pass through the drive plate 22 again. As mentioned above, the arc-shaped push plate 11 can be pushed back and forth by the arc-shaped protrusion 23 on the side wall of the drive plate 22 again, so that the above action can be repeated. During the upward movement of the dicing plate 3, the electromagnetic control valve in the powder injection pipe 19 closes and stops the falling thickening powder. This can effectively and thoroughly blow the previously falling thickening powder and coat the outside of each layer of fruit pieces, further ensuring that all fruit pieces can be coated with thickening powder.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
