Description
Technical Field
[0001] This utility model relates to the field of fruit pulp separation machine technology, and in particular to a jujube pulp separation machine for jujube juice processing. Background Technology
[0002] In the jujube juice processing industry, the efficient separation of jujube pulp and pit is a key process to ensure product quality and production efficiency. Traditional devices typically use a single spiral blade to transport jujubes, which are then separated from the pulp through friction in a perforated cylinder. However, during the separation process, the jujubes tend to accumulate at the bottom of the cylinder due to gravity, with some jujubes overlapping each other and failing to make sufficient contact and friction with the perforations on the inner wall of the cylinder. This results in incomplete pulp separation of these jujubes, further reducing the utilization rate of raw materials. Therefore, improvements are needed to address these issues. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a jujube pulp separation machine for jujube juice processing.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a jujube pulp separator for jujube juice processing, comprising a housing, a support fixedly connected to the bottom surface of the housing, a guide box provided on the top surface of the housing, a feed hopper provided at one end of the top surface of the guide box, a protective box installed on the outer wall of one end of the housing, a motor installed inside the protective box, a main shaft rotatably disposed inside the housing coaxially fixed to the output shaft of the motor, a separation component provided on the outer wall of the main shaft, a screening component for screening jujubes of different sizes installed inside the guide box, a double-opening door installed on one end of the housing, a discharge port opened on the bottom surface of the housing, and a pulp collection tray movably provided at the lower end of the support below the discharge port.
[0005] Preferably, the screening assembly includes an inclined screen plate fixed to the upper end of the inner wall of the guide box. The higher end of the inclined screen plate is located at the end of the feed hopper. The top surface of the inclined screen plate has multiple sets of fruit drop holes of varying sizes, which are distributed step by step along the inclined direction. The box body is provided with a first feed inlet for small fruit diameter, a second feed inlet for medium fruit diameter, and a third feed inlet for large fruit diameter at the lower end of each set of fruit drop holes.
[0006] Preferably, the separation assembly includes a filter cartridge fixed to the inner wall of the housing. Two partitions are equidistantly arranged inside the filter cartridge, dividing the interior of the filter cartridge into three compartments. The three compartments are respectively connected to a first feed inlet, a second feed inlet, and a third feed inlet. A first rotating column, a second rotating column, and a third rotating column are sequentially arranged in the three compartments and are coaxially fixed to the main shaft. The shaft diameters of the first rotating column, the second rotating column, and the third rotating column decrease progressively. Spiral blades are coaxially fixed to the outer walls of the first rotating column, the second rotating column, and the third rotating column.
[0007] Preferably, the outer walls of the first rotating column, the second rotating column, and the third rotating column are evenly provided with multiple pulp fixing grooves, each adapted to small, medium, and large fruit diameters.
[0008] Preferably, the filter cartridge has three filter cartridge doors hinged to one end facing the box door, and the three filter cartridge doors correspond to the three compartments inside the filter cartridge. The outer wall of the filter cartridge is provided with limit switches at each of the three filter cartridge doors.
[0009] Preferably, an elastic scraping strip is provided between the blade of the spiral blade and the inner wall of the filter cylinder. One end of the elastic scraping strip is fixed to the edge of the spiral blade, and the other end of the elastic scraping strip extends into the filter hole of the filter cylinder through elastic deformation.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of an inclined screen plate with fruit drop holes, a first feed inlet, a second feed inlet, and a third feed inlet, uses the inclined screen plate to guide the jujubes to slide at an inclined angle. Jujubes of different sizes fall through the corresponding fruit drop holes to the appropriate feed inlets, facilitating accurate grading of jujubes according to fruit diameter and improving grading accuracy. This provides a suitable separation environment for jujubes of different sizes. Furthermore, through the cooperation of a rotating column with spiral blades and a pulp fixing groove, the spiral blades push the jujubes to move stably along the chamber, while the pulp fixing groove limits and fixes the jujubes, preventing them from overlapping and ensuring sufficient contact and friction between the jujubes and the inner wall of the filter cylinder. This improves the contact between the jujubes and the filter cylinder, enabling uniform and comprehensive pulp separation. Ultimately, this solves the problem of incomplete pulp separation caused by the accumulation and overlapping of jujubes in existing devices, thus improving the thoroughness of pulp separation and raw material utilization.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 4This utility model discloses a jujube pulp separator for processing jujube juice, comprising a housing 1, a support 2 fixedly connected to the bottom of the housing 1, a guide box on the top of the housing 1, a feed hopper 3 at one end of the top of the guide box, a protective box installed on the outer wall of one end of the housing 1, a motor 11 installed inside the protective box, a main shaft 12 rotatably mounted inside the housing 1 and coaxially fixed to the output shaft of the motor 11, a separation component on the outer wall of the main shaft 12, a screening component for screening jujubes of different sizes installed inside the guide box, a double-opening door 4 installed on one end of the housing 1, a discharge port on the bottom of the housing 1, and a pulp collection tray 5 movably mounted on the support 2 at the lower end of the discharge port; the housing 1 and the support 2 are made of 304 stainless steel, with high structural strength and corrosion resistance. The device is corrosion resistant and meets food processing hygiene standards, providing stable support for the equipment. Motor 11 uses a Y132S-4 type three-phase asynchronous motor, providing stable power output and enabling forward and reverse rotation control, providing reciprocating driving force for the separation components. The pulp collection tray 5 facilitates the centralized collection of pulp after separation, reducing material waste. These components together form the basic framework of the device, providing complete structural support for the core functions of jujube screening, pulp separation, and collection. The screening component includes an inclined screen plate 6 fixed to the upper end of the inner wall of the guide box. The higher end of the inclined screen plate 6 is located at the end of the feed hopper 3. The top surface of the inclined screen plate 6 has multiple sets of fruit drop holes, ranging in size, distributed progressively along the inclined direction. The housing 1 is located below each set of fruit drop holes. The system is equipped with a first feed inlet 8 for small-diameter fruits, a second feed inlet 9 for medium-diameter fruits, and a third feed inlet 10 for large-diameter fruits. The inclined screen plate 6 is made of 304 stainless steel, with a smooth surface that prevents material adhesion. Its inclined structure utilizes gravity to guide the jujubes as they slide, and the different sizes of fruit drop holes enable precise grading. The first feed inlet 8, second feed inlet 9, and third feed inlet 10 correspond to jujubes of different diameters, ensuring that the graded jujubes enter the appropriate compartments, improving the targeting of subsequent separation. The separation assembly includes a filter cylinder 7 fixed to the inner wall of the housing 1. Two partitions are equidistantly arranged inside the filter cylinder 7, dividing its interior into three compartments. These three compartments are connected to the first feed inlet 8, the second feed inlet 9, and the third feed inlet 10, respectively. The chamber is equipped with a first rotating column 13, a second rotating column 14, and a third rotating column 15, which are coaxially fixed to the main shaft 12. The shaft diameters of the first rotating column 13, the second rotating column 14, and the third rotating column 15 decrease progressively. The outer walls of the first rotating column 13, the second rotating column 14, and the third rotating column 15 are all coaxially fixed with spiral blades 16. The filter cylinder 7 is made of 304 stainless steel, and the filter hole diameter is adapted to the fruit pulp separation requirements, ensuring that the fruit pulp can be smoothly discharged and blocking the fruit pit. The three chambers correspond to different feed inlets, and the shaft diameters of the rotating columns decrease progressively to meet the separation space requirements of jujubes of different sizes. The spiral blades 16 rotate with the main shaft 12 in both directions, pushing the jujubes to move back and forth and generating squeezing and kneading force to enhance the fruit pulp separation effect.
[0015] In this invention, the outer walls of the first rotating column 13, the second rotating column 14, and the third rotating column 15 are evenly provided with multiple fruit pulp fixing grooves, each adapted to small, medium, and large fruit diameters. The size of the fruit pulp fixing grooves matches the diameter of the jujubes in the corresponding compartments, which can limit and fix the jujubes, preventing them from overlapping during reciprocating movement and ensuring that each jujube can fully contact and rub against the inner wall of the filter cylinder 7, thus improving the thoroughness of fruit pulp separation. Three filter cylinder doors 18 are hinged to the end face of the filter cylinder 7 facing the door 4. The three filter cylinder doors 18 correspond to the three compartments inside the filter cylinder 7, and limit switches 17 are rotatably provided on the outer wall of the filter cylinder 7 at each of the three filter cylinder doors 18. The filter cylinder doors 18 are made of 304 stainless steel. Made of stainless steel, it has good sealing performance to prevent leakage of fruit pits or pulp during the detachment process; the limit switch 17 can quickly lock or unlock the filter cylinder door 18, which facilitates the separate cleaning of fruit pits in each compartment after operation and is easy to operate; there is an elastic scraper between the blades of the spiral blade 16 and the inner wall of the filter cylinder 7. One end of the elastic scraper is fixed to the edge of the spiral blade 16, and the other end of the elastic scraper extends into the filter hole of the filter cylinder 7 through elastic deformation; the elastic scraper is made of food-grade silicone material, which has good elasticity and strong wear resistance and will not damage the inner wall of the filter cylinder 7; it moves synchronously with the spiral blade 16 in forward and reverse directions, which can clean the residual fruit pulp in the filter hole in real time, avoid filter hole blockage, ensure smooth discharge of fruit pulp, and improve the continuity of operation.
[0016] Working Principle: In use of this invention, jujube raw materials are fed into the guide box from the feed hopper 3. The raw materials fall onto the inclined screen plate 6 and slide along the surface with the help of the inclined angle of the screen plate. During the process, jujubes of different sizes fall through the corresponding fruit drop holes. Small-diameter jujubes enter the first chamber of the filter cylinder 7 through the first feed inlet 8, medium-diameter jujubes enter the second chamber through the second feed inlet 9, and large-diameter jujubes enter the third chamber through the third feed inlet 10, achieving precise grading of jujubes according to fruit diameter. Subsequently, the motor 11 starts, driving the main shaft 12 and the first rotating column 13, the second rotating column 14, and the third rotating column 15 in the three chambers to perform reciprocating forward and reverse rotation. The spiral blades 16 on the outer wall of each rotating column rotate synchronously forward and reverse, pushing the jujubes back and forth along the length of the chamber on the one hand, and generating a reverse kneading force on the other hand. At the same time, each rotating column... The pulp fixing groove on the column limits and fixes the jujubes, preventing them from overlapping during movement and ensuring that each jujube can fully contact and rub against the inner wall of the filter cylinder 7. Under the combined action of squeezing, kneading and friction brought about by the reciprocating forward and reverse rotation, the jujube pulp quickly separates from the pit. The separated pulp falls through the filter holes of the filter cylinder 7 to the bottom of the box 1, and finally falls into the pulp collection tray 5 through the discharge port for centralized collection. During the operation, the elastic scraping strip on the edge of the spiral blade 16 rotates forward and reverse synchronously with the blade, and extends into the filter holes of the filter cylinder 7 through elastic deformation to clean the residual pulp in real time and prevent the filter holes from clogging. After the operation is completed, open the box door 4 of the box 1, unlock the limit switch 17 on the door of the filter cylinder 7, and open the filter cylinder doors 18 of the three corresponding compartments respectively to remove the pits in each compartment and complete the cleaning. At this point, the device is in use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
