Description

Technical Field

[0001] This utility model relates to the technical field of coconut processing equipment, specifically a high-efficiency dehydration device for coconut jelly. Background Technology

[0002] Dehydration is a crucial step in coconut processing, directly affecting the coconut's shelf life, taste, and subsequent processing efficiency. Currently, coconut dehydration mainly employs methods such as natural sun-drying, centrifugal dehydration, or hot air drying.

[0003] Traditional methods of dehydrating coconut jelly often have many shortcomings. While the common method of natural sun-drying is low-cost, it is highly susceptible to weather conditions, has a long drying cycle, and is inefficient, making it difficult to meet the needs of large-scale production. In addition, some simple mechanical dehydration equipment may only remove water through a single means such as squeezing, which is not only insufficient in dehydration but also easily causes physical damage to the coconut jelly, affecting its integrity and taste.

[0004] In equipment with ventilation and drying functions, uneven airflow distribution often occurs, leading to inconsistent drying of coconuts. Some coconuts may become over-dried and deteriorate in texture, while others may retain too much moisture, which is detrimental to subsequent processing and storage. Furthermore, traditional equipment lacks an effective sorting mechanism during the dehydration process, making it impossible to classify coconuts of different sizes and moisture contents, further affecting the overall efficiency and quality of dehydration. Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The existing technology mentioned above has shortcomings and defects, namely, its inability to classify and process coconuts of different sizes and moisture contents, which affects the overall efficiency and quality of dehydration.

[0006] The present invention discloses a high-efficiency coconut dehydration device, including a dehydration box, a cylinder arranged horizontally inside the dehydration box, a rotating shaft rotatably mounted at the axis of the cylinder, a fixed frame mounted on the rotating shaft, a screening component mounted on the fixed frame, a drying component mounted on one side of the dehydration box, a feed inlet at the upper end of the dehydration box, a discharge outlet at the lower end of the dehydration box, and a shielding component between the discharge outlet and the cylinder.

[0007] Furthermore, the screening component includes multiple filter plates, which are evenly distributed around the circumference of the rotating shaft. The filter plates are mounted on the fixed frame, and each filter plate has a through hole of different size. The through holes on the upper end of the filter plate are distributed in descending order of size around the rotating shaft.

[0008] Furthermore, the air-drying assembly includes a hot air box and a filter screen. The hot air box is installed on the dehydration box and a fan is provided on the hot air box. A heating element is installed on the side of the hot air box near the dehydration box, and the filter screen is installed on the cylinder on one side of the heating element.

[0009] Furthermore, an air outlet pipe is provided on the side of the dehydration tank away from the hot air box, and a filter screen is provided between the air outlet pipe and the cylinder, with the filter screen installed on the cylinder.

[0010] Furthermore, the shielding assembly includes a baffle that is slidably mounted on the dehydration tank, and one side of the baffle is connected to the dehydration tank via a telescopic cylinder.

[0011] Furthermore, guide rods are provided at both ends of the baffle, the guide rods are installed on the dehydration tank, and the baffle is slidably disposed with respect to the guide rods.

[0012] Furthermore, two arc-shaped plates are provided between two adjacent filter plates, and the two arc-shaped plates are respectively installed at both ends of the fixing frame. The filter plates are connected to the fixing frame by fixing bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a fixed frame on the rotating shaft and installing multiple circumferentially evenly distributed filter plates with different through-hole sizes to form a screening component, can classify and process coconuts of different sizes and moisture contents, avoiding the impact of individual differences in coconuts on the overall dehydration efficiency and quality. At the same time, combined with the hot air box, fan, heating element and reasonably set filter screen in the air drying component, the hot air can act on the coconuts more evenly, solving the problem of uneven air distribution in traditional ventilation and drying equipment, ensuring that the coconuts are relatively uniformly dried, making the dehydration of coconuts more thorough, improving the overall dehydration efficiency and quality, and facilitating subsequent processing and storage.

[0014] 2. This utility model utilizes a combination of screening and air drying methods to minimize physical damage to the coconuts and maintain their good taste and integrity. Furthermore, its shielding components, with the help of sliding baffles, telescopic cylinders, and guide rods, can flexibly control the discharge situation and are not affected by weather factors during natural drying. It can operate stably in different environments and meet the requirements of large-scale production for coconut dehydration. Attached Figure Description

[0017] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Please see Figure 1 , Figure 2 The present invention relates to a high-efficiency dehydration device for coconut jelly, comprising a dehydration tank 1, wherein a cylindrical cylinder 2 is arranged horizontally inside the dehydration tank 1. The cylindrical cylinder 2 is made of 304 stainless steel and the surface is polished to reduce friction damage between the coconut jelly and the cylinder wall and to improve corrosion resistance. A rotating shaft 3 is rotatably installed at the axis of the cylindrical cylinder 2, and a servo motor is installed at one end of the rotating shaft 3. The speed of the servo motor can be adjusted by a controller. The servo motor is installed on the dehydration tank 1.

[0019] See Figure 2 , Figure 3 As shown, a fixed frame 4 is provided on the rotating shaft 3, and a screening component is provided on the fixed frame 4. The screening component includes a filter plate 5. Multiple filter plates 5 are provided and are evenly distributed around the circumference of the rotating shaft 3. The filter plates 5 are installed on the fixed frame 4. The edges of the filter plates 5 are rounded to prevent scratching the surface of the coconut when turning the coconut. Two arc-shaped plates 7 are provided between two adjacent filter plates 5. The two arc-shaped plates 7 are respectively installed at both ends of the fixed frame 4.

[0020] See Figure 2 , Figure 3As shown, the curvature of the arc plate 7 perfectly matches the curvature of the inner wall of the cylinder 2, and food-grade silicone strips are pasted on the edge of the arc plate 7 to fit tightly against the inner wall of the cylinder 2, further preventing the coconuts from slipping out of the gap between the filter plate 5 and the cylinder 2 during the turning process. The filter plate 5 is connected to the fixing frame 4 by fixing bolts. Each filter plate 5 is provided with a through hole 6, and the through hole 6 on each filter plate 5 is of a different size.

[0021] In this embodiment, the size of the through holes 6 at the upper end of the filter plate 5 is distributed from large to small around the rotating shaft 3. A drying assembly is provided on one side of the dehydration box 1. The drying assembly includes a hot air box 13 and a filter screen 16. The hot air box 13 is installed on the dehydration box 1. A fan 15 is provided on the hot air box 13. The fan 15 is a centrifugal fan. The air volume can be adjusted by a frequency converter to ensure that the hot air forms a stable airflow in the cylinder 2.

[0022] In this embodiment, a heating element 14 is installed on the side of the hot air box 13 near the dehydration box 1. The heating element 14 is a carbon fiber heating element, which provides uniform heating and a fast temperature rise. The power is adjustable to meet the dehydration needs of coconuts with different water contents. A filter screen 16 is installed on the cylinder 2 on one side of the heating element 14. The filter screen 16 has a double-layer structure, with an inner layer of stainless steel wire mesh and an outer layer of activated carbon filter screen. This can prevent coconut fragments from entering the hot air box 13 or the air outlet 17, and can also absorb the odors generated during the dehydration process.

[0023] In this embodiment, an air outlet 17 is provided on the side of the dehydration tank 1 away from the hot air box 13. A filter screen 16 is provided between the air outlet 17 and the cylinder 2. The filter screen 16 is installed on the cylinder 2. An inlet 8 is provided at the upper end of the dehydration tank 1. A flow control valve is installed at the inlet 8 to adjust the feeding speed according to the real-time amount of coconuts in the device, so as to avoid insufficient screening due to excessive feeding at one time. An outlet 9 is provided at the lower end of the dehydration tank 1. The outlet 9 is conical to facilitate the collection of dehydrated coconuts.

[0024] See Figure 2 , Figure 4 As shown, a shielding assembly is provided between the discharge port 9 and the cylinder 2. The shielding assembly includes a baffle 10, which is slidably installed on the dehydration box 1. A rubber sealing strip is provided at the contact part between the baffle 10 and the dehydration box 1 to prevent water from leaking from the discharge port 9 during the dehydration process. One side of the baffle 10 is connected to the dehydration box 1 by a telescopic cylinder 12.

[0025] The stroke of the telescopic cylinder 12 can be precisely controlled by a solenoid valve to achieve stepless adjustment of the baffle 10, meeting the discharge requirements of different amounts of coconuts. Guide rods 11 are provided at both ends of the baffle 10. The guide rods 11 are installed on the dehydration box 1. The baffle 10 and the guide rods 11 are slidably arranged. The surface of the guide rods 11 is coated with grease to reduce the frictional resistance when the baffle 10 slides.

[0026] The implementation principle is as follows: During the feeding stage, the coconuts to be dehydrated enter the device through the feed port 8 at the top of the dehydration box 1 and fall directly into the cylinder 2 horizontally set inside the dehydration box 1. At this time, the shielding component is in the closed state, which prepares for the subsequent screening and dehydration process. During the screening and turning stage, the rotating shaft 3 at the axis of cylinder 2 starts to rotate, driving the fixed frame 4 and screening components fixed on the rotating shaft 3 to rotate synchronously. The screening components consist of multiple filter plates 5 evenly distributed around the circumference of the rotating shaft 3. The arc-shaped plates 7 at both ends of adjacent filter plates 5 form a relatively closed area to prevent the coconuts from slipping off the edges of the filter plates 5 during turning. Since the size of the through holes 6 on each filter plate 5 is distributed from large to small along the circumference of the rotating shaft 3, as the filter plates 5 rotate, the coconuts roll on the filter plates 5 under the action of gravity and centrifugal force: larger coconuts cannot pass through the small diameter through holes 6 and will remain on the filter plate 5 with large through holes 6; smaller coconuts will fall onto the next suitable filter plate 5 through the through holes 6 of the corresponding size, realizing the accurate classification of coconuts of different sizes and water contents, and avoiding the impact of individual differences on the subsequent dehydration effect. During the air-drying and dehydration stage, the air-drying components are activated simultaneously with the sorting and classification. The fan 15 on the hot air box 13 draws in outside air, which is heated by the heating tube 14 to form hot air. This hot air is then blown evenly into the cylinder 2 through the filter screen 16 installed on the side of the cylinder 2. Since the coconuts have been sorted and dispersed on different filter plates 5, and the hot air circulates within the cylinder 2, the hot air enters from the side of the hot air box 13, is heated by the coconuts, and is discharged from the exhaust pipe 17 on the other side of the dehydration box 1. The filter screen 16 between the exhaust pipe 17 and the cylinder 2 also prevents the coconuts from clogging the pipe. The hot air can act evenly on each coconut, solving the problem of inconsistent drying caused by uneven airflow in traditional equipment. During this process, the rotation of the filter plate 5 continuously drives the coconuts to turn over, ensuring that all sides of the coconuts can come into contact with the hot air, resulting in more thorough dehydration. At the same time, it avoids physical damage to the coconuts caused by squeezing or other methods, maintaining their integrity and taste. During the discharge stage, once the coconuts have reached the preset dehydration standard, the discharge port 9 is flexibly opened by controlling the telescopic cylinder 12 to drive the baffle 10 to slide along the guide rod 11, based on the classification of coconuts on different filter plates 5. Since the screened coconuts have been classified according to size and moisture content, the opening and closing degree and time of the baffle 10 can be controlled to achieve separate or centralized discharge of different types of coconuts, meeting the needs of subsequent processing for coconut classification. The entire process is unaffected by weather and can operate continuously and stably, meeting the requirements of large-scale production.
