Abstract
Description
Technical Field
[0001] This utility model relates to the field of nut drying technology, and in particular to an air-source heat pump type macadamia nut drying device. Background Technology
[0002] Macadamia nuts, also known as macadamia nuts, have a fragrant, crisp, and smooth kernel with a unique creamy aroma. They are considered among the world's highest quality edible nuts, rich in protein, oils, minerals, and vitamins, offering excellent benefits for human growth and development, strengthening the body, and preventing disease. Due to their unique nutritional value and taste, macadamia nuts are highly sought after in the market. However, to maintain their quality, timely drying after harvesting is essential. Traditional drying methods, such as natural sun-drying and coal-fired drying, have many drawbacks, including requiring large spaces, being highly susceptible to weather conditions, easily attracting dust and other bacterial impurities, and difficulty in controlling the drying temperature.
[0003] Currently, air source heat pump drying technology, as a highly efficient, environmentally friendly, and energy-saving drying method, utilizes low-grade heat energy from the air for drying. Through complex processes such as compression, condensation, evaporation, and throttling of the heat pump system, heat energy is transferred to the items in the drying chamber, thereby achieving a rapid and uniform drying effect. Given the numerous advantages of air source heat pump drying technology, it has been widely used in the field of macadamia nut drying. However, in the actual drying process, the applicant has still discovered some shortcomings: the nuts tend to clump together in the container, making it difficult to ensure uniform heating, thus affecting the final drying effect of the entire batch of nuts. Therefore, this application provides an air source heat pump macadamia nut drying device to meet these needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an air-source heat pump type macadamia nut drying device to solve the problem of uneven heating in existing nut drying processes.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] An air-source heat pump type macadamia nut drying device includes a cylinder and an air-source heat pump body mounted on one side of the cylinder to blow hot air into the cylinder. A drying frame is embedded in the top of the cylinder, and a horizontal arm is mounted on the top of the cylinder. A shaft extending into the drying frame is vertically rotatably mounted at the bottom of the horizontal arm. A shaft block is connected to the bottom end of the shaft. A baffle is arranged radially along the shaft on the side wall of the shaft block. A drive motor for driving the shaft to rotate is mounted on the top of the horizontal arm.
[0007] Optionally, the dials are provided in pairs, with the bottoms of the pair of dials bent in the same direction of rotation.
[0008] Optionally, a toothed bar is vertically arranged on the top of the dial plate, and multiple toothed bars are arranged side by side.
[0009] Optionally, the hot gas output end of the air source heat pump body is covered with a gas guide cover, and a through hole communicating with the gas guide cover is opened at the bottom of the side wall of the cylinder.
[0010] Optionally, a wire mesh plate is provided at the bottom of the drying frame.
[0011] Optionally, the top of the cylinder body on the side away from the through hole is provided with a slot that allows the drying frame to be pulled out horizontally, and a handle is provided on the side wall of the drying frame.
[0012] Optionally, a bracket for supporting the drying frame is fixed at the middle position of the cylinder.
[0013] Optionally, a ball is provided at the top of the toothed rod.
[0014] Optionally, a support plate is provided at the bottom of the outer side wall of the cylinder, and an electric push rod is vertically installed on the top of the support plate. The cross arm is fixedly assembled to the telescopic end of the electric push rod.
[0015] Optionally, a pair of pallets and electric push rods are provided, with the pair of pallets and electric push rods symmetrically distributed on both sides of the cylinder body, and the two ends of the cross arm are fixedly connected to the telescopic ends of the pair of electric push rods respectively.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, nuts are placed into the drying frame through an air source heat pump and a mesh plate. The air source heat pump is started and blows hot air into the cylinder through the through holes. The hot air is blown onto the nuts through the mesh plate at the bottom of the drying frame, which can be used to dry the nuts. The drying method of continuously blowing hot air through the mesh plate is more conducive to the heat drying of the nuts.
[0018] By setting up the paddles, the drive motor is started to rotate the shaft, which in turn drives a pair of paddles to rotate via the shaft block. This paddles can move the nuts in the drying frame. The curved structure at the bottom of the paddles can also turn the nuts in the drying frame. The turned nuts are then separated by the multiple toothed rods at the top of the paddles, which can greatly loosen the nuts in the drying frame, ensuring that the nuts are heated evenly and improving the uniformity and drying effect of the nuts.
[0019] Through the slots opened on the cylinder and the electric push rods set on both sides of the cylinder, the drying frame is pushed horizontally into the cylinder from the slots and supported horizontally by the bracket. At this time, it can be used for drying nuts. Activating the electric push rod pushes the horizontal arm to rise, the paddle plate disengages from the drying frame, and the drying frame is pulled out of the cylinder from the slot, so that the dried nuts can be collected, which is convenient for the loading and unloading of nuts.

[0034] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of this utility model provides an air-source heat pump type macadamia nut drying device, including a cylinder 1 and an air-source heat pump body 2 mounted on one side of the cylinder 1, capable of blowing hot air into the cylinder 1. A drying frame 4 is embedded in the top of the cylinder 1, and a mesh plate 6 is provided at the bottom of the drying frame 4. The hot air output end of the air-source heat pump body 2 is covered with an air guide shroud 3. A through hole 15 communicating with the air guide shroud 3 is opened at the bottom of the side wall of the cylinder 1. Nuts are put into the drying frame 4, and the air-source heat pump body 2 is started to blow hot air into the cylinder 1 through the through hole 15. The hot air is blown onto the nuts through the mesh plate 6 at the bottom of the drying frame 4, which can be used to dry the nuts. The drying method of continuously blowing hot air through the mesh plate 6 is more conducive to the heat drying of the nuts.
[0035] like Figures 1 to 4 As shown, a horizontal arm 5 is horizontally mounted above the cylinder 1. A shaft 9 extending into the drying frame 4 is vertically rotatably mounted at the bottom of the horizontal arm 5. A shaft block 10 is connected to the bottom end of the shaft 9. A paddle plate 11 is radially arranged on the side wall of the shaft block 10 along the shaft 9. A drive motor 12 for driving the shaft 9 to rotate is mounted at the top of the horizontal arm 5. When the drive motor 12 is started, the shaft 9 rotates. The shaft 9 drives a pair of paddle plates 11 to rotate through the shaft block 10, which can move the nuts in the drying frame 4 so that the nuts are heated evenly.
[0036] like Figures 2 to 5 As shown, a pair of levers 11 are provided, with their bottoms bent in the same direction of rotation. Multiple toothed rods 17 are vertically arranged on the top of each lever 11. Utilizing the bent structure at the bottom of the levers 11, the nuts inside the drying frame 4 can be turned over. The turned nuts are then dispersed by the multiple toothed rods 17 on the top of the levers 11, significantly improving the even heating of the nuts and enhancing the drying uniformity and effect. A ball 18 is provided at the top of each toothed rod 17 to prevent it from puncturing the nuts.
[0037] like Figures 2 to 5 As shown, the top of the cylinder 1 on the side away from the through hole 15 has a slot 13 that allows the drying frame 4 to be pulled out horizontally. A handle 16 is provided on the side wall of the drying frame 4. A bracket 14 for supporting the drying frame 4 is fixed in the middle of the cylinder 1, which facilitates the removal or insertion of the drying frame 4 into the cylinder 1. A support plate 7 is provided at the bottom of the outer side wall of the cylinder 1. An electric push rod 8 is vertically installed on the top of the support plate 7. A cross arm 5 is fixedly assembled to the telescopic end of the electric push rod 8. There is a pair of support plates 7 and electric push rods 8. The pair of support plates 7 and electric push rods 8 are symmetrically distributed on both sides of the cylinder 1. The two ends of the cross arm 5 are fixedly connected to the telescopic ends of the pair of electric push rods 8 respectively. After the nuts are dried, the electric push rod 8 is activated to push the cross arm 5 up, and the lever 11 disengages from the drying frame 4, so that the drying frame 4 can be pulled out of the cylinder 1 from the slot 13 for easy collection of the dried nuts.
[0038] The working principle of the technical solution provided by this utility model is as follows:
[0039] In use, nuts are placed into the drying frame 4, and then the drying frame 4 is horizontally pushed into the cylinder 1 from the slot 13 and supported horizontally by the bracket 14. At this time, the air source heat pump 2 is started and blows hot air into the cylinder 1 through the through hole 15. The hot air is blown onto the nuts through the mesh plate 6 at the bottom of the drying frame 4, which can be used to dry the nuts. Further, a pair of electric push rods 8 are started to retract, driving the horizontal arm 5 to move down, so that the paddle plate 11 is embedded in the drying frame 4 and contacts the mesh plate 6. Then, the drive motor 12 is started to drive the shaft 9 to rotate. The shaft 9 drives the pair of paddle plates 11 to rotate through the shaft block 10, which can paddle the nuts in the drying frame 4. With the bending structure at the bottom of the paddle plate 11, the nuts in the drying frame 4 can be flipped. The flipped nuts are separated by the multiple toothed rods 17 at the top of the paddle plate 11, which can greatly loosen the nuts in the drying frame 4, ensuring that the nuts are heated evenly and improving the drying uniformity and drying effect. After the nuts are dried, start the electric push rod 8 to push the horizontal arm 5 up, and the paddle plate 11 will disengage from the drying frame 4. At this time, the drying frame 4 can be pulled out of the cylinder 1 from the slot 13, and the dried nuts can be collected.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
