[0036] Embodiment 1

[0037] The present embodiment relates to a jujube pulp cleaning device, which can improve the problem of water pollution in the processing of jujube kernels. The jujube pulp cleaning device includes a pre-cooling bin for pre-freezing the jujubes to be cleaned of pulp, and also includes a conveying part and a cleaning unit. Among them, the conveying part receives the jujubes output from the pre-cooling bin to carry the jujubes; the cleaning unit is located on the path of the jujubes, and includes a cutting part, a scraping part and a brushing part arranged in sequence, so as to sequentially constitute the operation of cutting the peel of the jujube, scraping the pulp and brushing the remaining pulp.

[0038] Based on the above design concept, an exemplary structure of the sour jujube pulp removal device of this embodiment is as follows: Figure 1 , Figure 2 and Figure 3 shown.

[0039] In order to efficiently remove the pulp of the sour jujube without water washing, the equipment of this embodiment adopts an assembly line configuration structure, including a removal unit 6 that sequentially performs operations such as scratching the peel of the sour jujube, scraping the pulp, and brushing off the remaining pulp, so that the sour jujube located on the conveying part 5 and in a moving state is processed. The removal unit 6 includes a scratching part 2, a scraping part 3, and a brushing part 4 that are sequentially arranged on the traveling route of the sour jujube.

[0040] The configuration structure of the conveying part 5 can be flexibly designed, for example, a conveyor belt can be used. However, in order to make the overall space of the device more compact, in this embodiment, Figure 2 and Figure 3 As shown, the conveying part 5 is configured as a cylinder, arranged horizontally, and is provided with a driving shaft 50 driven by an external motor. The driving shaft 50 drives the conveying part 5 to rotate as a whole to carry the sour jujubes to move along the outer peripheral surface of the conveying part 5.

[0041] At the same time, the cleaning unit 6 is arranged around the conveying part 5, and an annular cleaning space is formed between the cleaning unit 6 and the peripheral surface of the conveying part 5. Figure 3The rotation direction indicated by the middle arrow is in the annular cleaning space. The scratching part 2, the scraping part 3 and the brushing part 4 are sequentially arranged on the inner wall of the cleaning unit 6 along the rotation direction of the conveying part 5. At the same time, in order to prevent the sour jujube from rolling down from both sides of the conveying part 5, side plates 501 are arranged on both sides of the outer peripheral surface of the conveying part 5.

[0042] The conveying part 5 is designed to be cylindrical, and the cleaning unit 6 is arranged in cooperation so that the whole device has a cylindrical structure, which is beneficial to reducing the manufacturing cost of the device, saving its floor space, and improving the operating efficiency of the device.

[0043] like Figure 3 As shown, the inner wall of the cleaning unit 6 faces the outer peripheral surface of the conveying part 5, and a cleaning space is formed between the two, and the sour jujube is restricted to move in the cleaning space. Restricting the sour jujube to move in the cleaning space has a certain positioning effect on the sour jujube, which is conducive to the smooth progress of the scratching, scraping and cleaning operations.

[0044] At the same time, if Figure 2 As shown, the outer peripheral surface of the conveying part 5 carrying the sour jujube is densely covered with a plurality of protruding structures 500, and the sour jujubes scattered on the outer peripheral surface of the conveying part 5 are blocked and moved between adjacent protruding structures 500. By densely covering a large number of protruding structures 500 on the working surface of the conveying part 5, the sour jujubes are restricted in their positions, which can effectively prevent them from being scratched, scraped and rolled randomly during cleaning.

[0045] In conjunction with the above structure, the height of the cleaning space is generally designed to be between 1 and 2 times the diameter of the sour jujube. More preferably, the cleaning spaces corresponding to the cutting part 2, the scraping part 3 and the brushing part 4 should be configured in a form in which the height can be adjusted separately. For example, the height of the cleaning space corresponding to the cutting part 2 is adjusted to 1 to 2 times the diameter of the sour jujube, and can be adaptively adjusted according to the size of the sour jujube to be processed; the height of the cleaning space corresponding to the scraping part 3 is adjusted to about 1.5 times the diameter of the sour jujube; in the cleaning space corresponding to the brushing part 4, since it is basically for cleaning the jujube pits, the height of the cleaning space of this section should be adjusted to 1 to 2 times the diameter of the jujube pits.

[0046] According to the above adjustment requirements, the inner wall of the cleaning unit 6 can be divided into sections, and each section of the inner wall can be adjusted along the radial direction of the cleaning unit 6. In this way, the sour jujube or the jujube pit can be spread on the working surface of the conveying part 5, so that all the sour jujube or the jujube pit can be processed by the operation, thereby improving the operation effect of the equipment.

[0047] When starting to process sour jujube, Figure 1 and Figure 3As shown, the sour jujube should first be cooled and frozen to break the fiber tissue of the sour jujube pulp, which is conducive to the subsequent pulp removal operation. The jujube inlet 100 of the precooling warehouse 1 receives the sour jujube to be processed and enters the precooling warehouse 1. The sour jujube can be cooled to -60°C in the precooling warehouse 1 by liquid nitrogen or ethanol, etc., to complete the precooling treatment of the sour jujube.

[0048] Afterwards, the sour jujube is discharged through the lower jujube port 101 of the pre-cooling chamber 1 and enters the cleaning space through the inlet 601 of the device. As the conveying part 5 is rotating, with the help of the blocking effect of the protruding structure 500, the sour jujube intermittently rolls along the conveying part 5 along the annular cleaning space. Under the action of the surface of the conveying part 5, the sour jujube is intermittently rolled, which realizes the turning of the sour jujube, so that all parts of the surface of the sour jujube can be cleaned by the cleaning unit 6.

[0049] like Figure 3 As shown, preferably, the entrance 601 is arranged at the upper left of the device, and a blocking brush 602 is arranged in the cleaning space below the entrance 601. The blocking brush 602 can be installed and fixed on the inner wall of the cleaning unit 6 to prevent the sour jujube from falling against the traveling direction.

[0050] As the conveying part 5 rotates, the sour jujubes pass through the cutting part 2, the scraping part 3 and the brushing part 4 in sequence. The cutting part 2, the scraping part 3 and the brushing part 4 can all be arranged on the inner wall of the cleaning unit 6, and are arranged at a certain angle respectively, and have a certain travel distance. The angle distribution size can be adjusted according to the process conditions of each processing link.

[0051] A plurality of densely arranged cutting knives 200, scraping knives 300 and brushes 400 are respectively provided on the cutting part 2, the scraping part 3 and the brushing part 4 and are located in the cleaning space, so as to respectively complete the skin breaking, pulp scraping and cleaning operations of the sour jujube, and achieve an ideal pulp cleaning effect.

[0052] Preferably, the scratching tool 200 is a steel needle or a blade arranged along the moving direction of the sour jujube; the scraping tool 300 is a scraper, or a structure similar to the scraper on a grater can be adopted; the brush 400 is a hard bristle brush or a steel brush, and a food-grade stainless steel brush, or a hard plastic brush or a brown brush should be selected, because the pulp brushed off can also be used for other food processing. Preferably, a steel brush is used for the final cleaning work, which can minimize the residual pulp on the surface of the jujube pit, which is conducive to improving the overall processing effect of the equipment.

[0053] The above-mentioned cutting blade 200, scraping blade 300 and brush 400 and other working parts are preferably arranged in a gradually dense manner along the moving direction. The gradually dense arrangement is conducive to the progressive implementation of each working link and to improving the overall pulp removal effect.

[0054] At the same time, in order to collect the removed pulp in real time for subsequent processing, the scraping part 3 and the brushing part 4 are both provided with chambers for accommodating the removed pulp. Specifically, the scraping part 3 is provided with a pulp chamber 512, and the pulp scraped by the scraping tool 300 enters the pulp chamber 512 through the scraper outlet 301 of the scraping tool 300, and then is discharged through the pulp outlet 522 located on the right side of the device for collection. The brushing part 4 is provided with a residual flesh chamber 513, and at the same time, the brushes 400 are arranged in multiple rows arranged at intervals, and the inner wall of the cleaning unit 6 between each row is provided with a brush outlet 401, and the pulp brushed by the brush 400 enters the residual flesh chamber 513 through the brush outlet 401, and then is discharged through the residual flesh outlet 523 located at the lower right of the device for collection. In this way, the performance of the equipment can be greatly improved, and the effect of improving efficiency through continuous operation can be achieved.

[0055] Based on the above structure, in addition to the pulp outlet 522 and the residual flesh outlet 523 for discharging the removed pulp on the outer peripheral surface of the cleaning unit 6, a jujube kernel outlet 524 for discharging the jujube kernel is also provided. Preferably, the jujube kernel outlet 524 is provided at the bottom of the cleaning unit 6 and is connected to the tail section of the cleaning space. The sour dates processed through various operation links become jujube kernels and fall through the jujube kernel outlet 524 for collection. Meanwhile, in order to prevent the jujube kernels from adhering to the surface of the conveying part 5 and continuing to move with the conveying part 5, a blocking brush 603 can be provided in the cleaning space on the left side of the jujube kernel outlet 524. The blocking brush 603 can be a brush fixed on the inner wall of the cleaning unit 6. By cleaning the surface of the conveying part 5, the adhering jujube kernels are swept off; at the same time, the surface of the conveying part 5 after being cleaned continues to undergo the next processing process.

[0056] By providing an outlet for the removed pulp and a date pit outlet 524 for the date pit, the equipment can discharge the processed materials online. The arrangement position of each outlet is convenient for receiving and collecting each material, which can greatly improve the continuous operation performance and processing efficiency of the equipment.

[0057] The sour jujube pulp cleaning equipment described in this embodiment, by sequentially arranging a cutting part 2, a scraping part 3 and a brushing part 4 on the conveying part 5, makes the sour jujube go through the steps of pre-cooling, skin breaking, pulp scraping and brushing in sequence, and completes the pulp cleaning operation of the sour jujube under the process condition of no water washing, which not only has good processing efficiency, but also can improve the problem of water pollution in the process of sour jujube pit processing.

[0058] Embodiment 2

[0059] This embodiment also relates to a jujube pulp removal device, which is conducive to improving the problem of water pollution in the processing of jujube kernels. The jujube pulp removal device of this embodiment adopts the same design concept as the first embodiment, and an exemplary structure thereof is as follows: Figure 4 shown.

[0060] In the equipment of this embodiment, the conveying part 5 is in the form of a conveyor belt, and the conveyor belt of the conveying part 5 is driven by the roller on the driving shaft 50. Side plates 501 are arranged on both sides of the conveyor belt to prevent the hawthorns from rolling down. At the same time, the conveying part 5 is configured to be placed in sequence and have three groups with a height difference. The three groups of conveying parts 5 are respectively configured with a cutting part 2, a scraping part 3 and a brushing part 4. Among them, the first group is provided with a pre-cooling bin 1, and the hawthorns discharged from the pre-cooling bin 1 enter the first group of conveying parts 5 and are processed by the cutting part 2 arranged above it. After that, the hawthorns fall from the end of the first group of conveying parts 5 into the conveying part 5 of the second group, and are processed by the scraping part 3 arranged above it; and then enter the conveying part 5 of the third group for processing by the brushing part 4.

[0061] It should be noted that the travel speed and overall length of the conveyor belt of each group of conveying parts 5 can be flexibly set to suit the characteristics of different processing links. Preferably, the travel speed of each group of conveyor belts of the three groups of conveying parts 5 should be set gradually higher in sequence to respond to the different speed requirements of the cutting part 2, the scraping part 3 and the brushing part 4; for example, the speeds of the cutting part 2 and the scraping part 3 are slower, while the speed of the brushing part 4 is faster.

[0062] The above-mentioned cutting part 2, scraping part 3 and brushing part 4 form a cleaning space between the conveyor belt surface of the conveying part 5. The height of the cleaning space, the cutting tool 200 on the cutting part 2, the scraping tool 300 and the pulp cavity 512 on the scraping part 3, and the brush 400 on the brushing part 4 can all be set with reference to the contents of Example 1 and will not be repeated here.

[0063] Above the conveying part 5 of the second group, a pulp cavity 512 is arranged inside the scraping part 3, and the pulp outlet 522 of the pulp cavity 512 discharges the pulp from one side of the conveying part 5, and a pulp bin 502 can be arranged below the pulp outlet 522 to collect the pulp. On one side of the conveyor belt of the third group of conveying parts 5, a shorter side panel 501 can be arranged, and at the same time, each row of brushes 400 on the brushing part 4 can be arranged obliquely, and the pulp brushed by each row of brushes 400 is discharged from one side of the conveying part 5 along the oblique setting direction of the brushes 400, and collected by the residual pulp bin 503 below. Below the tail of the third group of conveying parts 5, a jujube pit bin 504 can be placed to collect the processed jujube pits.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
