Description

Technical Field

[0001] This invention relates to the field of jujube processing equipment technology, specifically to a batch cutting and peeling equipment and method for jujubes. Background Technology

[0002] Jujube is an important specialty economic fruit in my country, ranking first in the world in both yield and processing volume. The jujube peel is rich in polyphenols, dietary fiber, and natural antioxidants, while the pulp is rich in sugars, amino acids, and minerals, making it widely used in food, health products, and medicinal and edible products. However, the tough and tightly adhered jujube peel, irregular fruit shape, high sugar content, and strong surface stickiness make it difficult to directly adapt to traditional fruit and vegetable peeling equipment. In the deep processing of jujubes, the peeling process affects the effectiveness of subsequent sugaring, drying, grinding, and extraction processes, and also determines the product's appearance quality and yield. Incomplete peeling leads to uneven drying and color deviation; excessive peeling results in fruit pulp loss and reduced sweetness. Therefore, efficient, uniform, and low-damage jujube peeling technology has become one of the technological bottlenecks in the food equipment field in recent years. Currently, the mainstream peeling method commonly used by jujube processing enterprises is still wet sand milling. This method usually involves placing jujubes and abrasives such as quartz sand into a centrifugal rotating mill. The peel is removed through the combined action of high-speed friction and water washing. Although it can achieve batch processing, prolonged water washing will wash away the sugar and soluble active ingredients on the surface of the jujubes. In addition, some fruits will lose pulp due to uneven grinding, resulting in a decrease in yield. At the same time, the high-sugar wastewater generated by wet milling requires complex treatment before discharge, increasing operating costs, and by-products such as jujube peel particles cannot be recycled.

[0003] In addition, the mainstream methods for peeling jujubes both domestically and internationally also include three main categories: biochemical methods, thermophysical methods, and mechanical methods. Biochemical peeling technology: Chemical methods rely on alkaline solutions to break pectin glycosidic bonds at high temperatures, destroying the nutritional components of the fruit pulp; although enzymatic methods are gentle, enzyme preparations are expensive, the reaction rate is slow, making them unsuitable for large-scale production, and waste liquid treatment is complex, posing environmental and food safety risks. Thermophysical peeling technology: such as the vacuum pulsed infrared peeling device for jujubes disclosed in patent CN109619605A, which uses infrared heating and vacuum pulse to achieve thermal expansion and contraction peeling. Although there is no watering, jujubes are highly heat-sensitive and easily char. The equipment has high energy consumption, complex structure and high cost, which is not conducive to promotion. Mechanical peeling technology: such as the rotary grinding / peeling device disclosed in patents CN222171195U and CN211608165U, which uses wire brushes and friction rollers in combination with spray washing, relies on water medium for cooling, resulting in sugar loss, peel scraps that cannot be recovered, and the fruit body is easily over-weared, requiring an additional drying process, which has high energy consumption and cost. Existing jujube peeling technologies generally suffer from problems such as complex peeling equipment structure or poor applicability, inability to recover peel by-products, poor peeling uniformity, and high energy consumption and cost.

[0004] In summary, there is an urgent need for a new type of jujube peeling equipment and method to solve the above-mentioned defects. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a batch cutting and peeling device and method for jujubes, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A batch cutting and peeling device and method for red dates includes a base support, an outer cylinder, a cutting unit, and a cutting assembly. The base support has a mounting platform on top, a drive unit in the middle, an outer cylinder on top of the mounting platform, and the outer cylinder is fixedly connected to the base support. The cutting unit is in the middle of the outer cylinder, a cutting assembly is located at the bottom inner side of the cutting unit, and a chip removal mechanism is located at the bottom inner side of the outer cylinder. The cutting unit is coaxially distributed with the outer cylinder, and the cutting unit rotates in the opposite direction to the cutting assembly. The cutting unit includes an inner cylinder, a feeding rib, and a first cutting tool. The inner cylinder has a cylindrical hollow structure, with a feeding port at the top and a fixed connection between the bottom of the inner cylinder and the rotating shaft of the drive unit. Feeding ribs are provided on the inner side of the inner cylinder in a ring arrangement. A first cutting tool mounting hole is provided on the side of the inner cylinder, and a first cutting tool is provided above the first cutting tool mounting hole. Multiple sets of first cutting tool mounting holes and first cutting tools are arranged in a ring with staggered arrangement. The cutting assembly includes a cutter disc, which is rotatably connected to the inner cylinder. The middle part of the cutter disc is connected to the drive unit. Multiple second cutting tool mounting holes are evenly provided above the cutter disc, and a second cutting tool is provided above the second cutting tool mounting holes.

[0007] Furthermore, the inner cylinder has a discharge port on the outer side of the bottom and a jujube discharge pipe on the inner side of the inner cylinder. A jujube discharge channel is formed inside the jujube discharge pipe. A jujube discharge port is formed at one end of the jujube discharge channel and the other end of the jujube discharge channel is connected to the discharge port.

[0008] Furthermore, a discharge hopper is provided on the side of the outer cylinder, and a discharge port is provided on the outer side of the bottom of the inner cylinder. The jujube scraper slides in close contact with the chip removal mechanism.

[0009] Furthermore, the second blade is inclined, and multiple sets of dander collection holes are opened in the middle of the blade disc.

[0010] Furthermore, the chip removal mechanism includes a receiving tray, a chip outlet, and a chip trough. The receiving tray is fixedly connected to the outer cylinder, and a chip collection channel is formed between the receiving tray and the mounting platform. A chip outlet is provided in the middle of the receiving tray, and a chip trough is provided on the side of the receiving tray.

[0011] Furthermore, the chip removal mechanism also includes a chip scraper, which is mirror-distributed and fixedly connected to the drive unit shaft. The edge of the chip scraper slides against the top surface of the mounting platform and the inner wall of the outer cylinder.

[0012] Furthermore, the bottom of the mounting platform is provided with a shavings discharge hopper, which is inclined, and the top surface of the mounting platform is provided with a shavings discharge port, which is correspondingly set with the shavings discharge hopper.

[0013] A method for batch peeling and cutting red dates, the peeling method comprising the following steps: S1, Parameter Preset: Depending on the type of jujubes being processed, such as grey jujubes, select the appropriate tools for peeling, adjust the tool tilt angle, and set the speed of the cutting unit and cutting components. S2. Feeding and loading: The jujubes are continuously fed into the inner cylinder by a screw feeder, and the feeding speed of the jujubes is controlled to keep the amount of jujubes in the inner cylinder at 1 / 2 of the volume. S3, peeling: The inner cylinder rotates, and the feeding ribs drive the jujubes to roll evenly, so that the jujubes come into contact with the high-speed rotating blades at multiple angles, thus achieving the peel cutting of the jujubes. S4. Fruit peel and debris collection: The shavings generated during cutting are thrown towards the inner wall of the outer cylinder through the shavings collection hole under the action of centrifugal force. After being peeled off by the scraper, they are guided into the shavings discharge port and discharged from the shavings discharge hopper. S5, Red Date Filling: After peeling, the jujubes are discharged from the outlet through the jujube discharge pipe along the inner cylinder to the interlayer between the outer and inner cylinders and fall onto the top surface of the receiving tray. They are then discharged from the discharge hopper by the jujube scraper.

[0014] Furthermore, the cutting tools in S1 include cutting tool one and cutting tool two, which are used to cut and peel the jujubes. The specific steps are as follows: cutting tool one and cutting tool two, which are of the same model as the jujubes, are fixed above cutting tool mounting hole one and cutting tool mounting hole two by screwing or snapping. During the installation process, the micro-tilt angle of the cutting tools is adjusted so that the peeling depth of the jujubes is controllable and the peeled surface of the jujubes is uniform, effectively reducing damage to the fruit flesh and keeping the fruit intact.

[0015] Furthermore, the jujube scraper and scraper plate in S4 and S5 collect fruit peel debris and discharge jujube fruit by rotating. The jujube scraper and scraper plate are inclined and have a brush at the bottom.

[0016] This invention provides a batch cutting and peeling device and method for jujubes. Compared with the prior art, it has the following advantages: Dry peeling is achieved without continuous rinsing, which avoids the loss of sugar and soluble active ingredients in red dates from the source, while eliminating the need for subsequent drying, thus reducing energy consumption and processing costs. The dual-rotation collaborative mechanism of "low-speed inner cylinder rotation + high-speed cutter head cutting" is adopted. Combined with the inner cylinder guide structure and the micro-tilt design of the cutter, the jujubes are made to contact the cutter evenly from multiple angles. The peeling depth is controllable and the surface is uniform, which effectively reduces damage to the fruit pulp, keeps the fruit intact, and improves the product yield. By using centrifugal separation of peels and dry collection structure with scraper, the jujube peel particles are centrally recycled and utilized, increasing the added economic value of by-products, while avoiding the generation of sugary wastewater and reducing environmental treatment costs. The equipment adopts a purely mechanical structure, requiring no chemical reagents, heat sources, or complex vacuum systems. It has a simple structure, small footprint, and low cost and maintenance. Furthermore, it can be adapted to different jujube varieties by adjusting the rotation speed and changing the cutting tools, making it suitable for continuous and large-scale production. It has strong industrial applicability and promotional value. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0020] To address the technical problems in the background section, the following is provided: a batch cutting and peeling device and method for jujubes: Combination Figures 1-6As shown, the present invention provides a batch cutting and peeling device and method for jujubes, including a base support 1, an outer cylinder 3, a cutting unit 4, and a cutting assembly 5. The base support 1 has a mounting platform 11 on its top, providing support for the entire device. The base support 1 is constructed of welded steel and has leveling feet at the bottom to ensure stable operation. Its height and internal space are adapted to the installation layout of various functional systems. A drive unit 2 is located in the middle of the base support 1. The outer cylinder 3 is fixedly connected to the base support 1. The cutting unit 4 is located in the middle of the outer cylinder 3. The inner bottom of the cutting unit 4... The outer cylinder 3 is equipped with a cutting assembly 5, and a chip removal mechanism 6 is provided at the bottom of the inner side of the outer cylinder 3. The cutting unit 4 is coaxially distributed with the outer cylinder 3, and the cutting unit 4 rotates in the opposite direction to the cutting assembly 5. The cutting unit 4 includes an inner cylinder 41, a material guide rib 42, and a cutting tool 43. The inner cylinder 41 has a cylindrical hollow structure, and a feeding port is opened at the top of the inner cylinder 41. The bottom of the inner cylinder 41 is fixedly connected to the rotating shaft of the drive unit 2. The inner side of the inner cylinder 41 is provided with a material guide rib 42, which is arranged in a ring. The material guide rib 42 can be replaced with a guide spiral blade or a contoured labyrinth structure. The spiral angle of the guide spiral blade is 10°. When the inner cylinder 41 is low... During high-speed rotation, the jujubes are evenly distributed and form a rolling motion trajectory through their own structural guidance, allowing the jujubes to contact the high-speed rotating cutter at multiple angles, achieving three-dimensional dynamic cutting. The inner cylinder 41 has a cutter mounting hole 1 on its side, and a cutter 1 43 is positioned above the cutter mounting hole 1. Multiple sets of cutter mounting holes 1 and cutter 1 43 are arranged in a staggered ring. The cutting assembly 5 includes a cutter disc 51, which is rotatably connected to the inner cylinder 41. The middle of the cutter disc 51 is connected to the drive unit 2. Multiple cutter mounting holes 2 are evenly distributed above the cutter disc 51, and a cutter 2 52 is positioned above the cutter mounting holes 2. Each set of cutters... The blade 52 is tilted at a 1°–3° angle relative to the blade disc 51 to ensure that it only contacts the peel layer of the jujube and avoids damaging the flesh. The blade type can be adapted according to the jujube variety, including blades, serrated blades, piercing blades, etc., which are easy to change quickly. The blades can be replaced with equal-height suspended elastic support blades, or a multi-stage cutting blade combination of serrated blades and fine blades can be used. For example, four sets of coarse blades are set (3° angle) and four sets of fine blades are set (1° angle). By adjusting the speed ratio between the inner cylinder 41 and the blade disc 51, the blade type and the tilt angle, the equipment can be adapted to the peeling needs of different varieties and sizes of jujubes. By combining the cutting unit 4 and the cutting component 5, dry peeling of jujubes can be achieved without continuous rinsing, thus avoiding the loss of sugar and soluble active ingredients in the jujubes from the source. At the same time, the subsequent drying process is eliminated, reducing energy consumption and processing costs. Meanwhile, the dual-rotation synergy mechanism of the low-speed rotation of the inner cylinder 41 and the high-speed cutting of the cutter head 51, combined with the guiding structure of the inner side of the inner cylinder 41 such as the feeding rib 42 and the micro-tilt design of the cutter, allows the jujubes to contact the cutter evenly from multiple angles. The peeling depth is controllable, the fruit surface is uniform, effectively reducing damage to the fruit pulp, maintaining the integrity of the fruit, and improving the product yield. Drive unit 2 includes two independent motors: an inner cylinder 41 drive motor and a cutter head 51 drive motor, along with corresponding gear transmission mechanisms. The motors are variable frequency speed control motors, connected to an external control system via wires, allowing for precise speed adjustment. The inner cylinder 41 drive motor is connected to the bottom shaft of the inner cylinder 41 via a coupling, driving the inner cylinder 41 to rotate at low speed (10–30 r / min). The cutter head 51 drive motor is connected to the shaft of the cutter head 51 via a belt transmission mechanism, driving the cutter head 51 to rotate at high speed (300–800 r / min). Alternatively, the drive system can use a single motor with a gear differential to achieve differential rotation between the inner cylinder 41 and the cutter head 51, simplifying the structure and facilitating maintenance. In this embodiment, an outlet 44 is provided on the outer side of the bottom of the inner cylinder 41, and a jujube discharge pipe 7 is provided on the inner side of the inner cylinder 41. A jujube discharge channel is formed inside the jujube discharge pipe 7. A jujube discharge outlet is formed at one end of the jujube discharge channel, and the other end of the jujube discharge channel is connected to the outlet 44. The jujube discharge pipe 7, together with the outlet 44, can guide the peeled jujubes into the interlayer between the outer cylinder 3 and the inner cylinder 41, so that the jujube scraper 45 can discharge them later. In this embodiment, a discharge hopper 31 is provided on the side of the outer cylinder 3. The discharge hopper 31 is used to discharge the peeled fruit pushed by the jujube scraper 45. A discharge port 44 is provided on the outer side of the bottom of the inner cylinder 41. The jujube scraper 45 slides in contact with the chip removal mechanism 6. The jujube scraper 45 is evenly arranged around the inner wall of the outer cylinder 3. The jujube scraper 45 is made of elastic and wear-resistant rubber material. One end is in contact with the inner wall of the outer cylinder 3, and the other end is inclined towards the center. like Figures 2-7 As shown, based on the above implementation plan, this implementation plan further provides the following: To ensure that the peels and jujubes are separated and discharged separately, facilitating the recycling of the jujube peels, this implementation plan provides the following: The second cutter 52 is inclined, and multiple sets of skin collection holes 53 are opened in the middle of the cutter head 51. The skin collection holes 53 facilitate the collection of red date skins generated during the peeling of red dates inside the inner cylinder 41 into the skin collection channel. The diameter of the skin collection holes 53 is smaller than the minimum particle size of red dates and larger than the maximum particle size of skins. In this embodiment, the chip removal mechanism 6 includes a receiving tray 61, a chip outlet 62, and a chip trough 63. The receiving tray 61 is fixedly connected to the outer cylinder 3. A chip collection channel is formed between the receiving tray 61 and the mounting platform 11. The receiving tray 61 has a chip outlet 62 in the middle and a chip trough 63 on the side. The chip outlet 62 and the chip trough 63 are designed to allow the chips to fall into the chip collection channel, which facilitates the subsequent collection and discharge of jujube chips. With the cooperation of the chip collection channel and the jujube discharge channel, the jujube and chip can be separated and discharged in a dual-flow path. As an improvement to the above solution, the chip removal mechanism 6 also includes a chip scraper 64. The chip scraper 64 is distributed in a mirror image. The chip scraper 64 is fixedly connected to the rotating shaft of the drive unit 2. The edge of the chip scraper 64 slides against the top surface of the mounting platform 11 and the inner wall of the outer cylinder 3. The chip scraper 64 is made of elastic and wear-resistant rubber. The chip scraper 64 is inclined. The rotating chip scraper 64 can push and collect the jujube peels in the chip collection channel. The bottom of the mounting platform 11 is provided with a shavings discharge hopper 13, which is inclined. The top surface of the mounting platform 11 is provided with a shavings discharge port 12, which is correspondingly set with the shavings discharge hopper 13. When the jujube shavings pushed by the scraper 64 pass through the shavings discharge port 12, they will be discharged from the equipment by the shavings discharge hopper 13. By using centrifugal separation of jujube peels and a dry collection structure with a scraper plate 64, the jujube peel particles can be centrally recycled and utilized, increasing the added economic value of by-products while avoiding the generation of sugary wastewater and reducing environmental treatment costs.

[0021] A method for batch peeling and removing the skin from jujubes, comprising the following steps: S1, Parameter Preset: Depending on the type of jujubes being processed, such as grey jujubes, select the appropriate tool for peeling, adjust the tool tilt angle (e.g., adjust the tool micro-tilt angle to 2°), set the rotation speed of the cutting unit 4 and the cutting component 5, set the inner cylinder 41 rotation speed to 20 r / min, and the cutter head 51 rotation speed to 500 r / min. The cutting tools include cutting tool 43 and cutting tool 52, which are used to cut and peel the jujubes. The cutting tool 43 and cutting tool 52, which are of the same model as the jujubes, are fixed above the cutting tool mounting hole 1 and cutting tool mounting hole 2 by screwing or snapping. During the installation process, the micro-tilt angle of the cutting tools is adjusted to make the peeling depth of the jujubes controllable and the peeling surface of the jujubes uniform, effectively reducing damage to the fruit flesh and keeping the fruit intact. S2. Feeding and loading: The jujubes are continuously fed into the inner cylinder 41 by the screw feeder, and the feeding speed of the jujubes is controlled so that the amount of jujubes in the inner cylinder 41 is kept at 1 / 2 of the volume. This ensures that the jujubes have enough space to tumble, so as to ensure uniform peeling, improve processing consistency, reduce collision and squeezing between jujubes, and avoid contact between a single jujube and the high-speed blade for a long time. S3, peeling: The inner cylinder 41 rotates, and the feeding ribs 42 drive the jujubes to roll evenly, so that the jujubes come into contact with the high-speed rotating blades 52 at multiple angles. With the angled blades of the blades, the peel can be cut precisely without damaging the flesh. S4. Fruit peel and debris collection: The shavings generated during cutting are thrown towards the inner wall of the outer cylinder 3 through the shavings collection hole 53 under the action of centrifugal force and fall into the shavings collection channel. After being peeled off by the scraper 64, they are guided into the shavings discharge port 12 and discharged from the shavings discharge hopper 13. S5, Red Date Filling: After peeling, the jujubes are discharged from the outlet 44 through the jujube discharge pipe 7 along the inner cylinder 41 into the interlayer between the outer cylinder 3 and the inner cylinder 41 and fall onto the top surface of the receiving tray 61. They are then discharged from the discharge hopper 31 by the push of the jujube scraper 45. The jujube scraper 45 and the scraper 64 collect fruit peel debris and discharge the jujubes by rotating. The jujube scraper 45 and the scraper 64 are inclined and have brushes at the bottom.
