Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a device for peeling jujubes. Background Technology

[0002] Red dates, belonging to the genus Ziziphus of the family Rhamnaceae, originated in China and have a cultivation history of over 8,000 years. Since ancient times, they have been listed as one of the "Five Fruits" (chestnut, peach, plum, apricot, and date). They are rich in protein, vitamin C, vitamin P, as well as nutrients such as calcium and phosphorus. Among them, the vitamin C content ranks among the highest of fruits, earning them the title of "King of Vitamins." In the process of processing red dates, it is sometimes necessary to peel them, which requires the use of red date peeling processing equipment.

[0003] For example, a vacuum pulsed infrared peeling device and method for jujubes, disclosed in CN109619605A, includes a heating chamber, a vacuum system, an infrared heating system, and a control system. This device can effectively achieve intelligent adjustment of the vacuum level in the heating chamber, enabling rapid peeling of jujubes. Moreover, the peeled jujubes have no water stains on their outer surface and are clean. However, this vacuum pulsed infrared peeling device and method for jujubes requires the use of a lot of equipment and structures, such as a vacuum tank, a condenser unit, and a touch screen, to achieve the peeling of jujubes, resulting in high operating costs and subsequent maintenance.

[0004] For example, a jujube peeling machine with publication number CN205455893U includes a frame. This invention uses a steel brush on the inner wall of an abrasive outer cylinder and a spiral abrasive inner cylinder to peel jujubes faster. Moreover, it uses mechanical peeling instead of chemical peeling, which not only ensures the edible quality of the peeled jujubes but also improves processing efficiency, making it very valuable. However, this jujube peeling machine, using a steel brush and a spiral abrasive inner cylinder, can only scrape the jujube skin into small chunks. These small chunks formed by the jujube skin will be distributed to various locations inside the device under the movement of the jujube flesh and the impact of water flow, which is not conducive to subsequent cleaning work.

[0005] For example, a portable fresh jujube peeling and pitting machine with publication number CN107114807A uses a peeling cylinder with bristles on the inner wall for peeling. As the peeling cylinder rotates continuously, the bristles inside constantly brush the jujube skin, thus achieving the function of peeling cleanly and with extremely high efficiency. However, this portable fresh jujube peeling and pitting machine can only peel one jujube at a time, and the operator still needs to operate it manually throughout the process, which results in low work efficiency and a high degree of labor intensity. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a jujube peeling processing device, which solves the problems of high operating costs and subsequent maintenance of existing jujube peeling devices, which are not conducive to subsequent cleaning work, have low work efficiency, and require a high level of labor.

A fixed frame is fixed to the bottom end of the first bracket, and a second bracket is configured in the inner frame of the fixed frame. A first pressure roller is rotatably connected to the inner wall of the second bracket.

[0009] Preferably, an adjustment mechanism is installed on the first bracket;

[0010] The adjustment mechanism includes a first base fixedly connected to the outer wall of the first bracket, a first motor fixedly connected inside the first base, the output shaft of the first motor connected to a threaded rod via a coupling, and the threaded rod rotatably connected to the first bracket via a bearing, a second vertical plate threadedly connected to the outer circumference of the threaded rod, and the top outer wall of the second vertical plate slidably connected to the sliding groove of the first bracket, and the bottom end of the second vertical plate fixedly connected to the second bracket.

[0011] Preferably, the sealing element includes a discharge pipe fixedly connected to the inner wall of the opening of the workbench, a pair of locking blocks fixedly connected to the inner wall of the discharge pipe, a piston disposed below the locking blocks, and the piston being adapted to the inner wall of the discharge pipe, and a push rod fixedly connected to the bottom end of the piston.

[0012] Preferably, a winding mechanism is installed at the end of the plastic film furthest from the storage box;

[0013] The winding mechanism includes a pair of third vertical plates fixedly connected to the worktable surface, a winding roller rotatably connected between the pair of third vertical plates, a first pulley fixedly connected to the front end of the winding roller, a second base fixedly connected to the outer wall of the front end of the third vertical plate, and a second motor fixedly connected to the second base. The output shaft of the second motor is fixedly connected to a second pulley, and the second pulley is rotatably connected to the first pulley via a belt.

[0014] Preferably, a collection mechanism is installed at the top of the workbench;

[0015] The collection mechanism includes a collection box adapted to the groove of the workbench surface. A scraper is fixed to the inner wall of the collection box. A second electric push rod is fixed to the top plate at the top of the scraper. A third bracket is fixed to the telescopic end of the second electric push rod. A second pressure roller is rotatably connected to the inner wall of the third bracket.

[0016] Preferably, a pair of first stop bars are fixed to the top of the third bracket, and the first stop bars are adapted to the corresponding through holes in the top plate.

[0017] Preferably, handles are fixed to the front and rear outer walls of the collection box.

[0018] Preferably, a plurality of second stops are fixedly connected to the top of the first bracket, and the outer wall of the second stops is adapted to the corresponding through hole of the top plate.

[0019] Preferably, the plastic film has the same width as the storage box and the fixing frame.

[0020] Beneficial effects

[0021] This invention provides a jujube peeling and processing device, which has the following beneficial effects:

[0022] Through the coordinated operation of the storage box, plastic film, vacuum pump, sieve plate, and first pressure roller, when the storage box is under negative pressure, the plastic film can better adhere the jujubes to the sieve plate. Then, the first pressure roller squeezes the jujubes, which can separate the jujube skin from the flesh. The jujube skin can adhere better to the plastic film rather than the sieve plate, and the jujubes are not easy to run away when squeezed. Therefore, the jujube peeling effect is better, the use cost and later maintenance cost are relatively low, and a large number of jujubes can be peeled at one time, resulting in higher processing efficiency and lower labor intensity.

[0023] Through the coordinated operation of the scraper, winding roller, second pressure roller, collection box, and plastic film, the plastic film itself has a certain degree of elasticity. Since the skin of the jujube is attached to the plastic film and the flesh of the jujube is attached to the sieve plate, the plastic film expands under pressure, which allows the jujube skin to adhere better. When the plastic film is wound up by the winding roller, the scraper and the second pressure roller can scrape off the jujube skin adhering to the plastic film, thus preventing the jujube skin from blocking the sieve plate and making it easier for subsequent jujube peeling and skin cleaning.

The first pulley 19 drives the take-up roller 18 to rotate, so that the take-up roller 18 can perform unwinding and winding of the plastic film 5.

[0046] In this embodiment, a collection mechanism is further provided on the top of the workbench 1;

[0047] The collection mechanism includes a collection box 24 adapted to the groove of the workbench 1. A scraper 25 is fixedly connected to the inner wall of the collection box 24. A second electric push rod 26 fixedly connected to the top plate 7 is provided at the top of the scraper 25. A third bracket 27 is fixedly connected to the telescopic end of the second electric push rod 26. A second pressure roller 28 is rotatably connected to the inner wall of the third bracket 27.

[0048] A groove is machined on the surface of the workbench 1 so that the collection box 24 can be limited by the groove. A scraper 25 is installed on the collection box 24. The top of the scraper 25 is flat to avoid tearing the plastic film 5.

[0049] In this embodiment, the top end of the third bracket 27 is fixedly connected with a pair of first stop rods 29, and the first stop rods 29 are adapted to the corresponding through holes of the top plate 7.

[0050] Several through holes are machined inside the top plate 7, so that the first stop 29 can limit and support the third bracket 27 through the corresponding through holes in the top plate 7.

[0054] In this embodiment, the plastic film 5 is configured to have the same width as the storage box 2 and the fixing frame 10;

[0055] This allows the fixing frame 10 to better press the plastic film 5 onto the storage box 2, preventing easy air leakage.

[0056] It is worth noting that the electrical structures and other components involved in this application can be selected according to the user's needs, as long as they meet the requirements of this application. At the same time, the corresponding control methods and circuit connections are all existing technologies, which can be fully implemented by those skilled in the art, so they will not be described in detail here.

[0057] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0058] Example: When this device is needed, first connect the external power supply and control circuits of each electrical component. Then, place the washed, pitted, halved, and heated dates onto the sieve plate 3 with the skin side facing up. Next, start the second motor 21, which drives the first pulley 19 to rotate via the second pulley 22 and belt 23. The first pulley 19 drives the take-up roller 18 to rotate, causing it to unwind. The operator can then place the plastic film 5 over the storage box 2. Finally, start the first electric actuator 8, which is equipped with... The second stop lever 35 moves the first support 9, causing the first support 9 to move the fixed frame 10 until the fixed frame 10 presses the plastic film 5 onto the storage box 2. At the same time, the first support 9, in conjunction with the second vertical plate 16 and the second support 11, drives the first pressure roller 12 to squeeze the plastic film 5 and the dates on the sieve plate 3. Then, the vacuum pump 4 is started to evacuate the air from the storage box 2. When the plastic film 5 is subjected to negative pressure inside the storage box 2, the dates can be pressed onto the sieve plate 3 more effectively. After that, the first motor 14 is started to output... The output shaft drives the threaded rod 15 to reciprocate regularly, so that the threaded rod 15, in conjunction with the first bracket 9, drives the second vertical plate 16 to move. The second vertical plate 16 then drives the first pressure roller 12 to move through the second bracket 11. In this way, the first pressure roller 12 can squeeze the jujubes. Because the plastic film 5 itself has a certain elasticity, and the skin of the jujube is attached to the plastic film 5 while the flesh of the jujube is attached to the sieve plate 3, when the plastic film 5 is squeezed and expands, it can better adhere the jujube skin. The jujube flesh will then separate from the jujube skin through the sieve plate 3. At the same time, the plastic film 5 keeps the jujubes attached to the sieve plate 3, and the jujubes... When squeezed by the first pressure roller 12, it is not easy to run away. After the jujube squeezing is completed, the piston 33 can be pulled down by the push rod 34. This creates a downward suction force in the storage box 2, which allows the jujube pulp blocked in the holes of the sieve plate 3 to continue to move downward. Then, the fixed frame 10 is raised to restore the pressure inside the storage box 2 to normal. In this way, the jujube peeling process is completed using only electrical appliances such as motors and electric push rods. The cost of use and subsequent maintenance is relatively low. Moreover, a large number of jujubes can be peeled at one time, resulting in higher processing efficiency and lower labor intensity.

[0059] When the jujube peeling operation is completed, the jujube skin is still attached to the plastic film 5. The second electric push rod 26 can be activated, which, together with the first stop rod 29, moves the third support 27 downward. The third support 27 then moves the second pressure roller 28, pressing the plastic film 5 onto the scraper 25. The operator holds the end of the plastic film 5 away from the take-up roller 18 and starts the second motor 21, which works with the take-up roller 18 to perform the take-up operation. In this way, the scraper 25 can scrape the jujube skin attached to the plastic film 5 into the collection box 24 for collection, thus preventing the jujube skin from blocking the sieve plate 3 and facilitating the subsequent jujube peeling and skin cleaning work.
