Description

Technical Field

[0001] This utility model belongs to the technical field of jujube processing machinery, specifically relating to a jujube peeling device. Background Technology

[0002] Red dates are a nutritious fruit with important edible and medicinal value, and they are also an important specialty agricultural product. Before further processing red dates (such as red date jam, date paste, etc.), their skin needs to be removed. Furthermore, if eaten directly, the hard skin of red dates affects the taste and can also hinder digestion; therefore, peeled red dates are more popular.

[0003] Traditional peeling methods mainly rely on manual cutting with knives or rubbing, which is not only inefficient but also easily damages the fruit flesh. Some methods use alkaline solutions for peeling, which is complex and can affect the quality of the fruit flesh. Furthermore, these methods are difficult to meet the needs of large-scale processing and pose problems such as high labor intensity and safety hazards. Therefore, there is an urgent need for a jujube peeling machine to replace manual peeling and significantly improve peeling efficiency.

[0004] There are currently two main types of jujube peeling equipment. One type removes the jujube skin by friction, while the other type softens the skin with high-pressure steam, causing it to burst and fall off. The former type, which removes the skin by friction, is more convenient to use, while the latter type, which removes the skin by steam, can prevent the jujube flesh from being ground away, but the process is more complicated.

[0005] In the prior art, Chinese patent document CN222171195U describes a jujube peeling device, including a base, a rubbing disc rotatably mounted on the base, and the rubbing disc being connected to a drive device mounted on the base. A baffle is fixed on the base to cooperate with the rubbing disc, and the baffle is equipped with a feeding and discharging system. Both the inner wall of the baffle and the rubbing disc have rough surfaces. This jujube peeling device has the following shortcomings: First, the jujube peels are inconvenient to collect for secondary use. During processing, the jujube peels accumulate directly at the bottom of the base, which is messy and not clean enough. Second, the peeled jujubes are inconvenient to remove from the baffle. Third, the degree of peeling needs to be manually observed and judged, which is not convenient to use. Fourth, during the peeling process, jujube peel particles easily adhere to the rubbing disc, causing a decrease in the peeling capacity of the rubbing disc and an increase in load, which is not conducive to energy saving.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] In one embodiment, a jujube peeling device is provided, such as... Figure 1-3As shown, the jujube peeling equipment includes a frame 10, which is welded from angle steel or square steel. A peeling processing chamber 20 is mounted on the frame 10. The interior of the peeling processing chamber 20 is used to polish the jujube skin. A pulsator 30 is located at the bottom inner side of the peeling processing chamber 20. The pulsator 30 rotates to continuously tumble the jujubes inside the peeling processing chamber 20. A pulsator shaft 40 is located within the frame 10, and the pulsator 30 is mounted on the pulsator shaft 40. A power device 50 is mounted on the frame 10 to drive the pulsator shaft 40 to rotate, thereby driving the pulsator 30 to rotate. The inner wall of the peeling processing chamber 20 and the surface of the pulsator 30 are both friction surfaces. Metal burrs can be created by punching holes in the inner wall of the peeling processing chamber 20 and the surface of the pulsator 30, or by using quartz sand processing to create a rough surface for the inner wall of the peeling processing chamber 20 and the pulsator 30. The frame 10 is provided with a jujube skin storage compartment 60 located below the impeller 30. The jujube skin storage compartment 60 is used to store the jujube skin that has been worn off from the jujubes. The jujube skin storage compartment 60 is formed by a skin plate 11 arranged around the frame 10 and a bottom plate 12 arranged in the frame 10.

[0040] like Figure 3 As shown, the base plate 12 includes an inclined jujube peel slide section 121. The upper edge of the jujube peel slide section 121 is welded to the inner side of the skin plate 11 on the right side of the frame 10. A horizontal plate section 122 for stacking jujube peels is provided on the lower side of the jujube peel slide section 121. Jujube peels that fall onto the jujube peel slide section 121 will slide onto the horizontal plate section 122. The lower side of the jujube peel slide section 121 transitions to the horizontal plate section 122 via a vertical plate section 123. The front and rear sides of the horizontal plate section 122, the jujube peel slide section 121, and the vertical plate section 123 are all welded to the inner sides of the skin plates 11 on the front and rear sides of the frame 10. Figure 2 As shown, a date peel outlet 124 is provided on the side of the frame 10, located on the upper side of the horizontal plate 122. An insert plate 125 is provided on the outside of the date peel outlet 124. Insert plate grooves 1251 are provided at both ends of the outside of the date peel outlet 124, and the insert plate 125 is inserted into the insert plate grooves 1251.

[0041] By setting up 60 jujube peel storage bins to uniformly store the jujube peels that have been polished, it is convenient to collect the jujube peels for secondary use, such as making feed or fertilizer. Furthermore, the collected jujube peels do not pile up directly at the bottom of the base, keeping the workshop clean and hygienic.

[0042] Furthermore, such as Figure 3As shown, a bushing 126 is provided on the jujube peel slide 121. The bushing 126 passes through and is welded to the middle of the jujube peel slide 121. The impeller shaft 40 passes through the bushing 126. A leather cup 127 is provided between the upper side of the bushing 126 and the impeller shaft 40. An annular groove is provided in the middle of the upper side of the bushing 126. The lower part of the leather cup 127 is set in the annular groove. The leather cup 127 is made of food-grade material and can be made of silicone. A seal is formed between the leather cup 127 and the impeller shaft 40.

[0043] like Figure 3 As shown, the power unit 50 is located on the lower side of the jujube peel slide 121 in order to make full use of the space inside the frame 10. The power unit 50 includes a variable frequency motor 51, which is connected to the impeller shaft 40 through a transmission mechanism 52. Here, the transmission mechanism 52 is a belt drive mechanism, and the speed of the variable frequency motor 51 can be adjusted according to the needs.

[0044] Furthermore, such as Figure 3 As shown, in one embodiment, a sensor bracket 71 is provided on the top of the peeling processing chamber 20, and a sensor 70 for identifying the degree of peeling is provided on the sensor bracket 71. The sensor bracket 71 is an iron plate welded to the outer side of the top of the peeling processing chamber 20. The sensor 70 is located directly above the center of the peeling processing chamber 20. The sensor 70 can be a camera or a laser sensor that can identify color. The peeled jujube flesh is light brown, while the unpeeled flesh is red. The degree of peeling can be determined by identifying the color through the sensor.

[0045] like Figure 1 As shown, a controller 80 is also mounted on the rack 10. The variable frequency motor 51 and the sensor 70 are electrically connected to the controller 80. The controller 80 has a touch screen and a keypad, which can adjust the speed of the variable frequency motor 51. After the signal collected by the sensor 70 is sent to the controller 80, the controller 80 can analyze it to determine whether to stop the variable frequency motor 51. The controller 80 stores software for image analysis or analysis of LiDAR-acquired signals. This software is provided by the manufacturer of the purchased sensor; for example, it can use a camera module from Imaging Precision, model DFM61BUC02-ML.

[0046] Combination Figure 3 and Figure 4 As shown, the impeller 30 includes a disc 31, on which multiple impeller blades 32 are provided. Jujube peel through holes are distributed on both the disc 31 and the impeller blades 32. The diameter of the jujube peel through holes is about 3mm. These holes are used to prevent jujube peel from adhering to the disc 31 and the impeller blades 32 and thus hindering the rotation of the impeller 30. They also allow the jujube peel to fall into the jujube peel storage compartment 60 below.

[0047] This jujube peeling equipment is equipped with sensors that can automatically identify the degree of peeling, eliminating the need for manual observation and judgment, making it more convenient to use. Furthermore, by incorporating jujube peel perforations on the impeller 30, the amount of jujube peel particles adhering to the impeller 30 during the peeling process is reduced, preventing a decrease in the impeller 30's peeling capacity and avoiding excessive load on the impeller 30 due to carrying a large amount of jujube peel, thus contributing to energy conservation.

[0048] Furthermore, in another embodiment, such as Figure 3 As shown, the peeling processing chamber 20 includes a cylindrical inner liner 21. Both the inner liner 21 and the impeller 30 are die-cast using quartz sand and food-grade resin to ensure compliance with food processing requirements. The outer side of the inner liner 21 is equipped with a stainless steel outer shell 22. An annular top plate 23 is located on the top of the stainless steel outer shell 22. The center of the annular top plate 23 is the jujube inlet 24. A jujube pulp output channel 25 is located at the bottom side of the peeling processing chamber 20. A sealing head 90 is installed in the jujube pulp output channel 25. Figure 5 As shown, the sealing head 90 includes an inner disc 91 and an outer cover 92. A connecting rod 93 is provided between the inner disc 91 and the outer cover 92. The inner side of the inner disc 91 matches the inner side of the peeling processing chamber 20. The inner side of the inner disc 91 is also a rough surface. When the sealing head 90 is placed in the jujube pulp output channel 25, the inner disc 91 can ensure that the inner wall surface of the peeling processing chamber 20 maintains a complete annular polishing surface. The outer cover 92 matches the outer opening of the jujube pulp output channel 25. A sealing disc 921 for sealing the outer port of the jujube pulp output channel 25 is provided on the inner side of the outer cover 92.

[0049] When the sealing head 90 is opened, the peeled jujube pulp can be output from the jujube pulp output channel 25 under the rotation of the impeller 30. A container can be placed outside the jujube pulp output channel 25 to receive it. Furthermore, the lower end of the jujube pulp output channel 25 is lower than the top surface of the impeller's disc 31, so that the jujube pulp particles can be completely output from the jujube pulp output channel 25 by the impeller 30, avoiding the retention of some jujube pulp on the disc 31. This makes it easier to remove the peeled jujubes from the peeling processing chamber 20 without manual removal.

[0050] Furthermore, such as Figure 3 As shown, the frame 10 is provided with an upper bearing seat 13 and a lower bearing seat 14 for mounting the impeller shaft 40. The upper bearing seat 13 is close to the bottom of the impeller 30, and the lower bearing seat 14 is located on the lower side of the jujube peel storage compartment 60. Both the upper bearing seat 13 and the lower bearing seat 14 are provided with bearings that match the impeller shaft 40. The upper bearing seat 13 and the lower bearing seat 14 are fixed to the frame 10 by support rods. By setting the upper bearing seat 13 and the lower bearing seat 14, the stability of the impeller shaft 40 is ensured.

[0051] Combination Figure 3As shown, the frame 10 of the jujube peeling machine has an inner step, and the peeling processing chamber 20 is supported on the inner step. The jujube pulp output channel 25 is inserted into the frame 10 and the peeling processing chamber 20. The peeling processing chamber 20 and the jujube pulp output channel 25 can be removed from the frame 10 for cleaning. The impeller blades 32 of the impeller 30 are inclined spirals, which can evenly turn the jujubes. The inner liner 21 is made of high-hardness quartz sand with a particle size of 0.5-1.5mm and a wear resistance life of ≥2000 hours. The variable frequency motor 51 has a rated power of 1.2-2.0kW and supports variable frequency speed regulation. In addition to detecting the degree of peeling, the sensor 70 can also detect the size of the jujubes, so that the controller 80 can control the speed of the variable frequency motor 51 to match the friction intensity with the size of the jujubes. The higher the speed, the stronger the friction. The operation interface on the controller 80 supports preset processing modes.

[0052] The performance parameters of this jujube peeling machine are as follows: peeling rate: 95%~98%; fruit pulp integrity rate: ≥90%; processing capacity per unit time: 100~300kg / h; suitable jujube diameter: 18mm~38mm; noise level: ≤65dB; power consumption: ≤1.8kWh / h; equipment dimensions: length 1200mm × width 800mm × height 1000mm; weight: approximately 180kg.

[0053] The equipment specifications can be adjusted according to processing needs.

[0054] The industrial version of the jujube peeling machine has a 50L peeling chamber, suitable for large-scale food processing plants, processing up to 50kg of jujubes per batch in 5 minutes. The rural cooperative version has a 30L processing chamber, a portable design, and can process 30kg of jujubes per batch, suitable for agricultural product processing cooperatives. The home version has a 5L processing chamber and a 400W power, suitable for home kitchens, agritourism businesses, and specialty restaurants.

[0055] The jujube peeling machine adopts a safe and environmentally friendly design concept for all components, is made of food-grade materials, and meets national food machinery safety standards.
