[0001] This utility model relates to the field of cocoa bean processing technology, specifically a cocoa bean drying device. Background Technology

[0002] Drying is a crucial step in the cocoa bean processing, directly affecting the quality, shelf life, and subsequent processing effectiveness. High-quality drying effectively removes excess moisture from cocoa beans, inhibits microbial growth, and preserves their unique flavor and nutrients.

[0003] According to CN211316887U, a raw material drying device for chocolate processing is disclosed. This technology discloses a device comprising a drying rack, a conveyor belt, a cover plate, and a drying pipe. The drying rack has a conveying trough, and the conveyor belt is placed in the conveying trough, with both ends of the conveyor belt fitted onto a drive shaft. The cover plate is located on the upper side of the drying rack, with an air inlet and an air outlet on the upper side of the cover plate, and an air supply pipe on the lower side of the cover plate. The air supply pipe is connected to the air inlet and the air outlet at both ends, respectively. The air inlet is connected to a hot air pipe, and the air outlet is connected to an exhaust pipe. The drive shaft is mounted on the walls of the drying trough at both ends, and a drive motor is connected to the drive shaft. The drive motor is electrically connected to a controller. This invention uses a conveyor belt to move the raw material, which is then dried by the upper air supply pipe during the movement, resulting in high drying efficiency and good drying effect.

[0004] However, in the aforementioned comparative documents, the heating method is mostly unilateral heating, which results in uneven heating of the upper and lower surfaces of the cocoa beans, easily leading to localized over-drying or under-drying, seriously affecting product quality. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a cocoa bean drying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a support frame and a heating component for heating gas. A drying chamber is fixedly mounted on the top of the support frame, and a conveyor belt is fixedly mounted on the support frame. The heating component is mounted on the drying chamber. An upper conveyor pipe is fixedly connected inside the drying chamber, and an upper nozzle is fixedly mounted on the upper conveyor pipe. A lower conveyor pipe is fixedly connected inside the support frame. A guide pipe is fixedly connected between the lower conveyor pipe and the upper conveyor pipe. The guide pipe is fixedly inserted through the drying chamber and the support frame. A lower nozzle is fixedly mounted on the lower conveyor pipe, and the lower conveyor pipe is located inside the conveyor belt.

[0007] Preferably, the heating assembly includes a heating box fixedly connected to the top of the drying oven, and a heating wire is fixedly connected inside the heating box to heat the transmitted gas.

[0008] Preferably, a heat-conducting cylinder is fixedly connected inside the heating box, and an auger is fixedly connected inside the heat-conducting cylinder to fully heat the gas.

[0009] Preferably, a fan is fixedly installed on the top of the drying box, and an air outlet pipe is fixedly connected to the air outlet of the fan. The heating box is connected to the air outlet pipe to transmit airflow to the heating component.

[0010] Preferably, a diversion pipe is fixedly connected to the upper transmission pipe, the diversion pipe is fixedly connected through the top of the drying box, and a top pipe is fixedly connected to the diversion pipe. The top pipe is fixedly connected to the center of the top of the heating component to facilitate the transmission of hot air.

[0011] Preferably, the air inlet of the fan is fixedly connected to an air inlet hood, a first filter screen is fixedly connected inside the air inlet hood, and a second filter screen is fixedly connected inside the air inlet hood. The first filter screen and the second filter screen are arranged left and right to separate impurities in the gas during the transmission process.

[0012] Preferably, a flat plate is fixedly connected to the support frame, and ventilation holes are provided on the conveyor belt to ensure that cocoa beans are evenly distributed on the conveyor belt.

[0013] This invention provides a cocoa bean drying device. It has the following beneficial effects:

[0014] The heating components heat the flowing airflow. The heated gas is then transported to the interior of the upper conveyor pipe via the combined use of the top pipe and the branch pipe. The conveyor belt facilitates the laying and transport of cocoa beans. The upper conveyor pipe, upper nozzle, lower conveyor pipe, and lower nozzle work together to evenly dry the cocoa beans on top of the conveyor belt, forming a three-dimensional heating mode. This ensures that each cocoa bean receives sufficient and uniform drying treatment, guaranteeing the quality of the dried cocoa beans.

[0015] The heating wires work together to raise the temperature inside the heating chamber. The combined use of the heat-conducting cylinder and the auger slows down the gas flow, thus ensuring that the gas is fully heated.

[0016] By using the first and second filters together, impurities in the gas during the transmission process are separated, preventing impurities from adhering to the surface of the cocoa beans and ensuring the cleanliness and drying quality of the cocoa beans. Attached Figure Description

An upper conveyor pipe 9 is fixedly connected inside the drying chamber 2 and is located above the conveyor belt 3. Multiple upper nozzles 10 are fixedly mounted on the upper conveyor pipe 9 and are evenly distributed on the upper conveyor pipe 9. A lower conveyor pipe 12 is fixedly connected inside the support frame 1 and is located below the upper conveyor pipe 9. A guide pipe 11 is fixedly connected between the lower transmission pipe 12 and the upper transmission pipe 9. The guide pipe 11 is fixedly connected through the drying chamber 2 and the support frame 1. A lower nozzle 13 is fixedly installed on the lower transmission pipe 12. The lower transmission pipe 12 is located inside the conveyor belt 3. Two sets of lower nozzles 13 are provided. The two sets of lower nozzles 13 are inclined on the lower transmission pipe 12. The airflow is heated by the heating component 6. Some of the hot air remains in the upper transmission pipe 9, and the other part of the hot air is transmitted to the interior of the lower transmission pipe 12 through the guide pipe 11. Then, the hot airflow is discharged through the upper nozzle 10 and the lower nozzle 13 respectively, forming a three-dimensional heating mode to ensure that each cocoa bean can be fully and evenly dried.

[0025] The heating assembly 6 includes a heating box 61 fixedly connected to the top of the drying oven 2. Heating wires 63 are fixedly connected inside the heating box 61. There are four heating wires 63, which are evenly distributed inside the heating box 61. When the heating wires 63 are in operation, the temperature inside the heating box 61 rises accordingly.

[0026] A heat-conducting cylinder 62 is fixedly connected inside the heating box 61. The heat-conducting cylinder 62 is mainly made of copper and has good thermal conductivity. An auger 64 is fixedly connected inside the heat-conducting cylinder 62. The auger 64 makes the gas flow upward in a spiral, which facilitates the full heating of the upward-flowing gas.

[0027] Reference Figure 2-4 A fan 4 is fixedly installed on the top of the drying box 2. The fan 4 is located on one side of the top of the drying box 2. The air outlet of the fan 4 is fixedly connected to the air outlet pipe 5. The heating box 61 is connected to the air outlet pipe 5. After the fan 4 is running, the gas is transmitted to the bottom of the heating box 61 through the air outlet pipe 5.

[0028] Reference Figure 2-4 A diversion pipe 8 is fixedly connected to the upper transmission pipe 9. The diversion pipe 8 is fixedly connected to the top of the drying box 2. A top pipe 7 is fixedly connected to the diversion pipe 8. The top pipe 7 is fixedly connected to the center of the top of the heating component 6. There are two diversion pipes 8. The two diversion pipes 8 are symmetrically distributed with the central axis of the top pipe 7 as the center. The airflow heated by the heating component 6 is transmitted to the upper transmission pipe 9 through the top pipe 7 and the diversion pipe 8.

[0029] Reference Figure 4 The air inlet of the blower 4 is fixedly connected to the air inlet cover 14. The air inlet cover 14 is fixedly connected to the first filter screen 15 and the second filter screen 16. The diameter of the filter holes on the first filter screen 15 is larger than the diameter of the filter holes on the second filter screen 16. The first filter screen 15 and the second filter screen 16 are arranged side by side. The first filter screen 15 and the second filter screen 16 filter the gas in sequence, separating impurities in the gas during the transmission process and preventing impurities from adhering to the surface of the cocoa beans.

[0030] Reference Figure 1 A flat plate 17 is fixedly connected to the support frame 1. The flat plate 17 is set at an angle, which allows the cocoa beans to be evenly spread on the conveyor belt 3, ensuring that each cocoa bean can be fully and evenly dried. The conveyor belt 3 is provided with ventilation holes to facilitate the circulation of hot air.

[0031] Working principle:

[0032] like Figure 1-4 As shown:

[0033] Outside gas first enters the intake hood 14. Inside the intake hood 14, the first filter 15 and the second filter 16 separate and filter impurities in the gas, removing dust, particulate matter, and other impurities to ensure the cleanliness of the gas entering subsequent systems. The filtered gas, under the action of the fan 4, enters the fan 4 through its inlet and then is transmitted to the outlet duct 5 through the fan 4's outlet. The outlet duct 5 then delivers the airflow to the heating assembly 6. The heating wire 63 heats the transmitted gas, and the heat-conducting cylinder 62 and its auger 64 further enhance the heating, ensuring the gas is fully heated, uniform, and sufficient. The heated gas then passes through the top pipe 7, which is fixedly connected to the center of the top of the heating box 61. Entering the diversion pipe 8, the gas is transmitted through the upper transmission pipe 9 and then sprayed downwards through the upper nozzle 10 fixed on the upper transmission pipe 9, acting on the cocoa beans on the conveyor belt 3. Another part of the hot airflow is transmitted from the upper transmission pipe 9 to the lower transmission pipe 12 through the guide pipe 11. The lower transmission pipe 12 is located inside the conveyor belt 3. After being transmitted through the lower transmission pipe 12, the hot airflow is sprayed upwards through the lower nozzle 13 fixed on the lower transmission pipe 12, heating and drying the cocoa beans from below the conveyor belt 3. The flat plate 17 fixedly connected to the support frame 1 ensures that the cocoa beans are evenly distributed on the conveyor belt 3. At the same time, the ventilation holes opened on the conveyor belt 3 facilitate the flow of hot air from the top and bottom, ensuring that the cocoa beans are evenly heated and fully dried.

[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
