[0001] This utility model relates to the technical field of agricultural product deep processing equipment, and in particular to an integrated drying and packaging machine for dried fruit. Background Technology

[0002] As a tropical snack food that combines flavor and nutrition, dried jackfruit requires two core processing steps: drying and dehydration, and quantitative packaging. However, the traditional processing model currently used in the industry has many technical pain points and cannot meet the needs of large-scale and standardized production.

[0003] In traditional processing, drying and packaging processes rely on independent equipment. The packaging accuracy depends on manual weighing, which is affected by the operator's experience and skill level. The packaging weight error often exceeds ±5 g, which does not meet the standardization requirements of food processing and is prone to secondary contamination, further affecting product quality.

[0004] Therefore, existing technologies still have shortcomings and deficiencies, and there is an urgent need for an integrated equipment that combines drying and packaging functions with high packaging accuracy to meet the actual needs of industrial processing of dried jackfruit. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated drying and packaging machine for dried fruit, which solves the technical problem that the drying and packaging processes in traditional processing rely on separate equipment and have low packaging accuracy.

[0007] A drying oven, wherein the top of the drying oven is provided with a first feed inlet and a second feed inlet;

[0008] The storage component includes a main feeder and a replenishing feeder fixedly disposed inside the drying chamber. The top opening of the main feeder corresponds to the first feed inlet, and the top opening of the replenishing feeder corresponds to the second feed inlet.

[0009] A weighing and dispensing platform is located directly below the replenishing component and is used to receive and weigh the dried fruit.

[0010] A conveying mechanism is located inside the drying chamber, directly below the main feeder, and is used to convey the dried fruit in the main feeder to the weighing and dispensing platform.

[0011] The replenishing component is used to replenish dried fruit to the weighing and dispensing platform when the weighing value of the weighing and dispensing platform does not reach the preset weight.

[0012] Preferably, an intake fan is fixedly installed on one side of the outer wall of the drying oven, and an exhaust fan is fixedly installed on the other side of the outer wall. A dehumidification device is installed at the intake fan.

[0013] Preferably, a sealing element is fixedly provided on the air inlet side of the air inlet fan, the dehumidification device is installed inside the sealing element, a fixing frame is fixedly provided on the side of the sealing element away from the air inlet fan, and a filter screen is fixedly provided at the fixing frame.

[0014] Preferably, it further includes a support frame, the support frame including four support legs, the four support legs being fixedly connected by a fixing ring, and the main feeder being fixedly mounted on the support frame through the fixing ring.

[0015] Preferably, the conveying mechanism is a conveyor belt, which is mounted on the support legs of the support frame.

[0016] Preferably, a limiting ring is fixedly provided on one of the support legs of the support frame, and the material replenishing component is fixedly provided to the support frame through the limiting ring.

[0021] Compared to the aforementioned background technology, the fruit drying and packaging integrated machine provided by this utility model has a weighing and packaging platform inside the drying chamber, which can integrate the drying and packaging operations of dried jackfruit. The dried jackfruit in the main feeding unit is automatically and continuously conveyed to the weighing and packaging platform through the conveying mechanism, providing the main part of the packaging weight. When the weighing value of the weighing and packaging platform is close to the preset value, a small amount of small-sized material is released by the replenishing component to supplement the weight and make fine adjustments to the packaging weight. This avoids the problem of excessive replenishment when using large pieces of material, thereby ensuring that the weight of each package is highly accurate and can meet the needs of large-scale and standardized production.

[0029] 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.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This utility model provides an integrated drying and packaging machine for dried fruit, which can integrate the drying and packaging operations of dried jackfruit. The main feeding component 12 provides the main part of the packaging weight, and the packaging weight can be finely adjusted by the supplementary feeding component 13, ensuring that the weight of each package is highly accurate and can meet the needs of large-scale and standardized production.

[0032] It should be noted that the processing object in this embodiment is dried jackfruit, but this device can also be used for drying and packaging similar dried fruits such as dried papaya and dried mango, and has a certain degree of versatility.

[0033] Please refer to this as well. Figures 1 to 5 The fruit drying and packaging integrated machine provided by this utility model includes:

[0034] Drying chamber 1, the top of drying chamber 1 is provided with a first feed inlet 17 and a second feed inlet 18;

[0035] The storage assembly includes a main feeder 12 and a replenishing feeder 13 fixedly installed inside the drying chamber 1. The top opening of the main feeder 12 corresponds to the first feed inlet 17, and the top opening of the replenishing feeder 13 corresponds to the second feed inlet 18.

[0036] The weighing and dispensing platform 15 is located directly below the material replenishment unit 13 and is used to receive dried fruit and weigh it.

[0037] The conveying mechanism is located inside the drying chamber 1, directly below the main feeding component 12, and is used to convey the dried fruit inside the main feeding component 12 to the weighing and dispensing table 15.

[0038] The replenishing component 13 is used to replenish dried fruit on the weighing and dispensing platform 15 when the weighing value of the weighing and dispensing platform 15 does not reach the preset weight.

[0039] Specifically, the drying oven 1 is a closed box structure, made of stainless steel, with a wall thickness of 2.5 mm, and dimensions of 80 cm long × 50 cm wide × 60 cm high; a door 2 is hinged on one side of the drying oven 1.

[0040] The main feeding unit 12 and the replenishing unit 13 are respectively equipped with a large-capacity storage tank and a small-capacity storage tank. Both the large-capacity storage tank and the small-capacity storage tank are made of food-grade PP material. The large-capacity storage tank has a diameter of 30 cm and a height of 60 cm (volume 63L), and the small-capacity storage tank has a diameter of 20 cm and a height of 40 cm (volume 25L). A valve (5 cm in diameter) is installed at the bottom of both the main feeding unit 12 and the replenishing unit 13. The material falling rate (0-100 g / s) can be controlled by adjusting the valve opening. The first feed port 17 has an inner diameter of 18 cm and a height of 10 cm, and the second feed port 18 has an inner diameter of 10 cm and a height of 8 cm. The first feed port 17 and the second feed port 18 are respectively connected to the main feeding unit 12 and the replenishing unit 13.

[0041] In use, first open the door 2 of the drying chamber 1, and evenly spread the jackfruit raw material to be dried in the drying chamber 1. Then close the door 2 to dry the jackfruit raw material. After drying, the dried jackfruit is sorted into simple categories. Whole or large pieces are fed into the main feeding component 12 through the first feeding port 17, and small pieces or fragments are fed into the replenishing component 13 through the second feeding port 18. Open the valve at the bottom of the main feeding component 12 and adjust the opening to control the feeding speed. At the same time, start the conveying mechanism to smoothly transport the jackfruit falling from the main feeding component 12 to the weighing and dispensing platform 15. The weight of the material is monitored in real time by the weighing and dispensing platform 15. When the weight value is close to the preset value, close the valve of the main feeding component 12 and stop the conveying mechanism. At this time, open the valve of the replenishing component 13 and add a small amount of small-sized jackfruit to the weighing and dispensing platform 15 until the weight reaches the standard.

[0042] This setup integrates the drying and packaging of dried jackfruit. The dried jackfruit in the main feeder 12 is automatically and continuously conveyed to the weighing and packaging station 15 via a conveying mechanism, providing the main portion of the packaging weight. When the weighing value of the weighing and packaging station 15 is close to the preset value, a small amount of small-sized material is released through the replenishing component 13 to supplement the weight and make a fine adjustment to the packaging weight. This avoids the problem of over-filling when using large pieces of material, thus ensuring that the weight of each package is highly accurate.

[0043] In some embodiments, an inlet fan 3 is fixedly installed on the outer wall of one side of the drying oven 1, and an exhaust fan 4 is fixedly installed on the outer wall of the other side. A dehumidification device 5 is installed at the inlet fan 3.

[0044] Please refer to this as well. Figures 1 to 4 Both the intake fan 3 and the exhaust fan 4 are 120 W axial flow fans, symmetrically installed on the upper part of the two side walls of the drying chamber 1. The intake fan 3 can draw outside air into the drying chamber 1, and the air flows in the drying chamber 1, carrying away the moisture evaporated from the jackfruit. The dehumidification device 5 can continuously reduce the humidity of the air in the chamber, prevent back dampness, and ensure drying efficiency and quality. The exhaust fan 4 exhausts the humid air out of the chamber, forming an effective air circulation.

[0045] In addition, a check valve is installed on the exhaust side of the exhaust fan 4. By setting the check valve, it is possible to prevent outside air from flowing back into the drying chamber 1 from the exhaust fan 4.

[0046] Optional, please refer to them as well. Figures 1 to 4 The dehumidification device 5 uses a semiconductor dehumidification module with a dehumidification capacity of 0.8 L / day, and is connected to an external controller. A humidity sensor is also installed inside the drying chamber 1. The dehumidification device 5 can be automatically started and stopped by the controller based on the feedback from the humidity sensor inside the chamber, so as to stabilize the relative humidity inside the chamber at 30%-40% and prevent the dried jackfruit from becoming damp again.

[0047] In some embodiments, a sealing element 6 is fixedly provided on the air inlet side of the air inlet fan 3, the dehumidification device 5 is installed inside the sealing element 6, a fixing frame 8 is fixedly provided on the side of the sealing element 6 away from the air inlet fan 3, and a filter screen 7 is fixedly provided at the fixing frame 8.

[0048] Please refer to the details as well. Figures 2 to 4 The sealing element 6 is a rectangular structure formed by four sealing plates. The sealing plates are made of silicone and have dimensions of 52 cm long × 62 cm wide and 4 mm thick. A 5 mm wide elastic sealing strip is pasted on the edge of the sealing element 6. It is connected to the drying box 1 by magnetic attraction and is located on the air inlet side of the inlet fan 3. The dehumidification device 5 is installed on the inside of the sealing element 6.

[0049] The fixed frame 8 is a rectangular frame structure, and the filter screen 7 is made of 304 stainless steel mesh with a mesh size of 0.8 mm and dimensions of 70 cm in length and 45 cm in width. The filter screen 7 is connected to the fixed frame 8 by clips. After installation, the filter screen 7 is a certain distance away from the inlet fan 3 (e.g., 10 cm) to ensure that all air entering the drying chamber 1 is filtered by the filter screen 7, intercepting dust particles and ensuring cleanliness.

[0050] In some embodiments, the fruit drying and packaging integrated machine provided by this utility model further includes a support frame 9, which includes four support legs and a fixing ring 11 fixedly connected between the four support legs. The main feeding component 12 is fixedly mounted on the support frame 9 through the fixing ring 11.

[0051] Please refer to this as well. Figures 4 to 5 The support frame 9 is made of stainless steel and includes four support legs arranged in a rectangular array. The four support legs are fixedly connected to a fixing ring 11. The main feeder 12 is limited and fixed by the fixing ring 11. A fastening bolt can be threaded onto the fixing ring 11. By tightening the fastening bolt, one end of the fastening bolt can abut against the main feeder 12, further improving the reliability of the fixation.

[0052] After the main feeder 12 is fixed to the support frame 9 by the fixing ring 11, its bottom outlet is a certain distance away from the conveying mechanism, for example, the gap is maintained at 4 cm, so that the material can fall smoothly. The bottom of each of the four support legs is equipped with an adjustable foot, the height of which can be adjusted from 50 to 80 cm. The distance between the outlet of the main feeder 12 and the conveying mechanism can be adjusted as needed by adjusting the foot.

[0053] In some embodiments, the conveying mechanism is a conveyor belt, which is mounted on the support legs of the support frame 9.

[0054] Please refer to this as well. Figures 4 to 5The conveying mechanism is a conveyor belt installed on the support frame 9, located below the discharge port of the main feeder 12. The conveyor belt is made of food-grade PU material, with a width of 25 cm, a length of 120 cm, and a thickness of 1.8 mm. The surface has diamond-shaped anti-slip embossing with a height of 0.8 mm. The conveyor belt is equipped with a 100 W geared motor, which drives the conveyor belt to work. The conveying speed is adjustable (0.5-2 m / min).

[0055] Optionally, a tensioning mechanism is provided between the support frame 9 and the conveyor belt. The tension of the conveyor belt can be adjusted through the tensioning mechanism to prevent slippage during conveying.

[0056] After long-term use, the conveyor belt may become loose due to wear, causing slippage during conveying and affecting the stability of material conveying. The conveyor belt is installed on the support frame 9 by two spaced rollers. The tensioning mechanism can adjust the distance between the two rollers, thereby adjusting the tension of the conveyor belt. It can be adjusted without disassembling the conveyor belt, without the need for professional maintenance, reducing the equipment failure rate.

[0057] In some embodiments, a limiting ring 14 is fixedly provided on one of the support legs of the support frame 9, and the feeding component 13 is fixedly provided on the support frame 9 through the limiting ring 14.

[0058] Please refer to this as well. Figures 4 to 5 Limiting rings 14 are fixedly connected to two supporting legs on one side of the support frame via connecting rods. The replenishing component 13 is limited and fixed by the limiting rings 14. Fastening bolts can be threaded onto the limiting rings 14. By tightening the fastening bolts, one end of the bolt abuts against the outer wall of the replenishing component 13, further improving the reliability of the fixation and ensuring load-bearing stability. After the replenishing component 13 is fixed to the support frame 9 by the limiting rings 14, its bottom outlet is a certain distance from the weighing and dispensing platform 15 for easy replenishment.

[0059] In some embodiments, the drying oven 1 is further provided with a base 16, which is located below the side of the support frame 9 where the limiting ring 14 is provided, and the weighing and dispensing platform 15 is fixedly installed on the top of the base 16.

[0060] Please refer to this as well. Figures 4 to 5 The base 16 is located on one side of the support frame 9, at the end of the conveying direction of the conveying mechanism. The material in the main feeder 12 can be conveyed forward by the conveying mechanism until it falls on the weighing and dispensing platform 15, providing the main part of the dispensing weight. The replenishing component 13 is located above the weighing and dispensing platform 15. When the weighing value of the weighing and dispensing platform 15 is close to the preset value, a small amount of small-sized material is released by the replenishing component 13 to replenish the weight and make fine adjustments to the dispensing weight, ensuring that the weight of each dispensing is highly accurate.

[0061] In this embodiment, the base 16 is made of cast iron, with a 5 mm thick silicone anti-slip pad attached to the bottom. The anti-slip pad has a Shore hardness of 60-70 degrees, which can increase the friction with the bottom surface of the drying oven 1 and prevent the equipment from shifting due to vibration during operation. The surface of the base 16 is coated with a wear-resistant coating with a thickness of 0.1-0.2 mm, which is easy to clean and wear-resistant, reducing dust accumulation during processing.

[0062] In some embodiments, the weighing and dispensing platform 15 includes an electronic scale and a dispensing tray. The electronic scale is fixedly mounted on the top of the base 16, and the dispensing tray is mounted on the electronic scale.

[0063] Specifically, the electronic scale has a weighing range of 0-5 kg ​​and a weighing accuracy of ±1 g. It can be fixed to the top of the base 16 with bolts. The dispensing tray is made of PP material (30 cm long × 25 cm wide × 5 cm high), with a Teflon non-stick coating on the inner wall. It can be connected to the electronic scale with clips for easy disassembly and cleaning. The electronic scale is equipped with a weight-reaching audible and visual alarm device. When the weight of the material in the dispensing tray reaches the preset value, an alarm will be triggered immediately to remind the operator.

[0064] In some embodiments, both the first feed port 17 and the second feed port 18 are hinged with a sealing cover, the sealing cover is made of transparent material, and the edge of the sealing cover is provided with a sealing ring.

[0065] The sealing cover is located at the first feed inlet 17 and the second feed inlet 18, and is connected to the top outer wall of the drying chamber 1 via a hinge. Specifically, a transparent acrylic cover can be used, allowing operators to observe the remaining material in the main feeder 12 and the replenishment feeder 13 through the transparent cover, facilitating timely replenishment. A 3 mm thick silicone sealing ring is attached to the edge of the sealing cover, ensuring a tight seal against the feed inlets after closing, preventing dust from entering.

[0066] The sealing cap can open to a maximum angle of 180°. This 180° opening angle prevents the sealing cap from blocking the feed inlet. Operators can quickly load the material using a shovel or funnel. The smaller hinge angle improves loading efficiency and makes it easier to load large quantities of dried jackfruit from the feed inlet.

[0067] In some embodiments, the sidewalls of the main feeder 12 and the replenishing feeder 13 are provided with scale lines.

[0068] Both the main feeding component 12 and the replenishing component 13 have scale lines pasted on their side walls. The scale lines are in "L" units, clearly marking capacity nodes such as 10L, 20L, and 30L. With the help of the transparent sealing cap, the remaining amount of material can be judged more accurately.

[0069] When observing only through the transparent sealing cap, it is easy to misjudge the amount of material due to visual errors. The scale line can provide a quantitative reference. When the material drops to the lowest scale line, the operator can replenish the material in time, avoiding production line shutdown due to insufficient material and improving processing continuity.

[0070] This utility model provides an integrated fruit drying and packaging machine. The drying chamber 1 uses an inlet fan 3, an exhaust fan 4, and a dehumidification device 5 to control humidity and prevent dust, ensuring drying quality. The main feeding unit 12 and the replenishing unit 13 store materials separately. The main feeding unit 12 makes fine adjustments to the packaging weight to ensure accurate packaging. The entire device has a stable structure and is easy to operate. All parts in contact with materials are made of food-grade materials, meeting food safety standards. It can be widely used in jackfruit drying workshops, agricultural cooperatives, and food production enterprises to meet the needs of large-scale processing.

[0071] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0072] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
