Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable processing technology, specifically relating to a high-efficiency passion fruit peeling device. Background Technology

[0002] Passion fruit, a tropical fruit rich in vitamins, amino acids, and bioflavonoids, has its pulp and juice widely used in food processing industries such as beverages, jams, and jellies. However, the passion fruit peel is tough and contains bitter components. If it is not thoroughly removed before processing, it will not only affect the taste of the product but may also increase impurities in the finished product due to the inclusion of fibers from the peel. Therefore, "peeling" has become a key pre-processing step in the deep processing of passion fruit. As the food industry develops towards large-scale and automated production, the market has placed higher demands on the efficiency, separation accuracy, and operational continuity of passion fruit peeling technology. However, existing peeling technologies still have many problems to be solved.

[0003] Traditional passion fruit peeling relies heavily on manual labor, with workers using knives to cut the peel and manually separating the pulp from the skin. While this method allows for direct control over the peeling process, it has significant limitations: Firstly, manual processing is extremely inefficient, with each worker handling only 80-120 passion fruits per hour on average, far from meeting the daily raw material processing needs of 1-3 tons for small and medium-sized food processing plants. Secondly, manual contact with raw materials poses hygiene risks and fails to meet aseptic standards for food processing. Furthermore, the repetitive nature of the process leads to worker hand fatigue, increasing labor costs and management complexity, and is gradually becoming unsuitable for the pace of modern production.

[0004] To address the drawbacks of manual peeling, semi-automatic peeling equipment has emerged in the industry, primarily divided into two types: cutting and friction. Cutting equipment uses rotating blades to cut open the passion fruit shell, then uses a brush roller to assist in separating the peel from the pulp. However, this technology has significant drawbacks: the blades are prone to uneven cutting depth due to the varying sizes of the passion fruit; if the cut is too shallow, the peel cannot be separated, while if it is too deep, the pulp will be shredded. Furthermore, the peel fragments produced during cutting easily get stuck in the gaps between the blades and the brush, requiring frequent machine stops for manual cleaning, severely impacting operational continuity. Friction equipment utilizes the protrusions on the inner wall of the roller to create friction with the passion fruit, causing the peel to crack and fall off. However, this method has poor peeling thoroughness, resulting in significant material waste. Additionally, juice seeps out during the friction process, easily forming clumps inside the roller, requiring frequent rinsing and maintenance, increasing water consumption and subsequent cleaning costs.

[0005] Furthermore, existing automated equipment typically uses single-layer, fixed filters, which are easily clogged by fruit pulp fibers during use, requiring frequent disassembly and cleaning, further reducing production efficiency. Additionally, the lack of independent power and compression chambers means the motor and transmission components are directly exposed to the compression environment, increasing the risk of juice leakage and electrical component failure, resulting in a high equipment failure rate. In summary, current passion fruit peeling technology fails to meet the demands of the food processing industry for large-scale, low-loss production in terms of efficiency, continuity, raw material utilization, and equipment stability. Developing a highly efficient, automated, and easy-to-maintain peeling device has become an urgent need for the industry.

Utility Model Content

[0007] This invention provides a highly efficient passion fruit peeling device, which aims to solve the technical problems mentioned in the background section.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A high-efficiency passion fruit peeling device includes a housing, an extrusion mechanism, and a feeding mechanism. The housing is horizontally divided into an upper chamber and a lower chamber by a partition. The lower chamber has a discharge port.

The outer side of the slider extends to the outside of the groove and is provided with a rack. The rack is meshed with the power assembly. The power assembly is located in the power chamber.

[0012] Preferably, the two sides of the second partition are respectively provided with a feed inlet and a clearance outlet at the upper end of the extrusion chamber and the power chamber.

[0013] Preferably, the bottom of the extrusion chamber is provided with a bottom groove that matches the bottom plate of the L-shaped unloading component, the bottom groove is provided with a juice guide port, and the bottom plate is provided with a filter screen.

[0014] Preferably, the power assembly includes a motor, a shaft, and gears.

[0027] 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.

[0028] Example

[0029] like Figures 1 to 3 As shown, a high-efficiency passion fruit peeling device includes a housing 1, an extrusion mechanism 2, and a guiding mechanism 3. The housing 1 is horizontally divided by a partition 4 to form an upper chamber 11 and a lower chamber 12. The lower chamber 12 is provided with a discharge port 121. The upper chamber 11 is vertically divided by a partition 5 to form an extrusion chamber 111 and a power chamber 112. The extrusion mechanism 2 is located in the extrusion chamber 111. The guiding mechanism 3 includes an L-shaped unloading component 31 and a power assembly 32. The partition 5 is vertically provided with a chute 51. The outer side of the L-shaped unloading component 31 is provided with a slider 311 that cooperates with the chute 51. The outer side of the slider 311 extends to the outside of the chute 51 and is provided with a rack 6. The rack 6 is meshed with the power assembly 32. The power assembly 32 is located in the power chamber 112.

[0030] Compared to traditional manual peeling and semi-automatic equipment, this device uses an integrated design that separates passion fruit juice and peel through extrusion, effectively improving work efficiency and eliminating the need to stop the machine to clean the peel, thus meeting the daily processing needs of small and medium-sized processing plants for small batches of raw materials.

[0031] In this embodiment, the two sides of the partition 2 5 are respectively provided with a feed inlet 7 and a clearance opening 8 at the upper end of the extrusion chamber 111 and the power chamber 112. The feed inlet 7 and the clearance opening 8 are used for feeding passion fruit and providing space for the L-shaped unloading component to slide upward out of the power chamber, preventing interference between components. In use, passion fruit is introduced into the feed inlet 7 from the external storage device and squeezed and crushed by the extrusion mechanism 2. Then the juice and peel are separated. The power component 32 drives the L-shaped unloading component 31 to slide upward out of the clearance opening 8, and the peel on the L-shaped unloading component 31 is separated.

[0032] In this embodiment, the bottom of the extrusion chamber 111 is provided with a bottom groove 100 that matches the bottom plate 312 of the L-shaped unloading component 31. The bottom groove 100 is provided with a juice guide port 200, and the bottom plate 312 is provided with a filter screen 300. The filter screen 300 can be a 100-mesh filter screen. The bottom groove 100 ensures that the extrusion surface is flat and avoids the problem of local unextrusion caused by the deviation of the passion fruit. Combined with the filter screen 300 of the bottom plate 312, the juice recovery rate is improved. At the same time, the filter screen 300 can intercept fruit pulp fibers and fruit peel fragments, significantly improving the purity of the juice. The cost of subsequent filtration processes is effectively reduced, and the waste of raw materials and impurities in the finished product are effectively reduced.

[0033] In this embodiment, the power assembly 32 includes a motor 321, a rotating shaft 322 and a gear 323. The motor 321 is located outside the power chamber 112 and its output end is connected to the rotating shaft 322. The rotating shaft 322 is rotatably connected inside the power chamber 112 and is provided with a gear 323, which meshes with the rack 6.

[0034] In this example, the feeding mechanism 3 is driven by the meshing transmission of gear 323 and rack 6, and the L-shaped unloading component 31 is automatically raised and lowered by motor 321. There is no need for manual opening of the box door to clean the fruit peels, which not only reduces the labor intensity of workers, but also avoids the hygiene hazards caused by manual contact with raw materials, and meets the aseptic standards of food processing. In addition, the power component 32 can be equipped with torque overload protection, which will automatically stop the machine when the fruit peels block it, reducing the risk of equipment failure and reducing the frequency of manual maintenance.

[0035] Please see the return Figure 1 and Figure 2 The extrusion mechanism 2 includes a cylinder 21 and an extrusion block 22. The cylinder 21 is located in the extrusion chamber 111, and its telescopic end is connected to the extrusion block 22. The extrusion block 22 is slidably connected in the extrusion chamber 111 via a slide rail 400. The extrusion block 22 is made of 316L stainless steel and is passivated to resist corrosion from the acidic juice of passion fruit. The slide rail 400 is a self-lubricating linear guide to reduce friction loss. The power component 32 is located in the power chamber 112 to prevent corrosion of electrical components caused by juice leakage.

[0036] The working principle of this utility model:

[0037] This utility model provides a high-efficiency passion fruit peeling device. In specific use, passion fruit is put into the feed port 7 at the upper end of the extrusion chamber 111 and falls onto the lower bottom plate 312 of the L-shaped unloading part 31. At this time, the L-shaped unloading part 31 is in the initial position, and its lower bottom plate 312 is precisely fitted with the bottom groove 100 at the bottom of the extrusion chamber 111 to form a flat extrusion bearing surface, ensuring that the passion fruit is placed stably and avoiding displacement during extrusion.

[0038] When cylinder 21 is activated, it pushes the extrusion block 22 along the slide rail 400 toward the passion fruit until appropriate extrusion force is applied. Under pressure, the passion fruit peel breaks, and the pulp and juice seep out. After being filtered by the filter screen 300 of the bottom plate 312 of the L-shaped unloading part 31, the juice passes through the juice guide port 200 on the bottom tank 100 and flows into the lower chamber 12 along the guide channel. Finally, it is discharged from the discharge port 121 of the lower chamber 12 to the external collection device, completing the initial separation of juice and peel. The peel remains on the L-shaped unloading part 31.

[0039] After the extrusion and separation are completed, the cylinder 21 drives the extrusion block 22 to reset; at the same time, the motor 321 of the power assembly 32 is started, the motor 321 drives the rotating shaft 322 to rotate, and the gear 323 on the rotating shaft 322 rotates synchronously. Through the meshing transmission between the gear 323 and the outer rack 6 of the slider 311 on the L-shaped unloading part 31, the L-shaped unloading part 31 is driven to slide upward along the slide groove 51 of the partition plate 2 5; when the L-shaped unloading part 31 rises to the clearance opening 8 at the upper end of the power chamber 112, its top extends out of the box body 1, and the operator can directly clean and collect the retained fruit peels to realize fruit peel recycling;

[0040] After the fruit peel is cleaned, the motor 321 reverses, the gear 323 drives the rack 6 to reverse the transmission, and the L-shaped unloading part 31 slides down the slide groove 51 to reset and re-fit with the bottom groove 100 of the extrusion chamber 111. At this time, the device returns to the initial state and new passion fruit can be added to repeat the above process to achieve continuous peeling operation.

[0041] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
