[0029] Example:
[0030] This embodiment provides a coffee fruit drying device for coffee production, referring to Figure 1, including a hollow drum 3, the drum 3 is horizontally placed on a bracket, the drum 3 can rotate horizontally around an axis, the coffee berries are placed in the drum 3, the drum 3 can be driven by a motor to rotate around the axis, so that the coffee berries inside are turned over, wherein a drainage component 2 is installed below the drum 3, and a hot air pipe 1 is installed at the end of the drainage component 2 facing away from the drum 3. The hot air pipe 1 is equipped with a fan and an electric heating wire, which can generate a temperature-carrying airflow required for drying, and the airflow will first enter the drainage component 2, and the drainage component 2 is provided with an air outlet 22 at one end facing the drum 3, and the airflow passes through the air outlet 2 2 is discharged from the drainage assembly 2, one end of the drainage assembly 2 having an air outlet 22 is arranged close to the outer wall of the drum 3, and a slit 32 is provided on the side wall of the drum 3, so that the airflow discharged from the air outlet 22 will directly enter the drum 3 through the slit 32, and a small part of the airflow will escape into the atmosphere, thereby improving the utilization rate of hot air. At the same time, because the drainage assembly 2 is located directly below the drum 3, the coffee cherries will also gather at the lower inner side of the drum 3, and when the air is discharged, it can fully contact the coffee cherries, and the accumulated coffee cherries will be blown upward and thrown, thereby further improving the drying efficiency.
[0031] In a further embodiment, referring to Figure 2 The drainage component 2 includes a main body 31, which is cylindrical and has a space for accommodating coffee fruits. A material opening is opened on the circumferential side wall of the main body 31. The main body 31 can rotate, and the material opening is vertically upward for adding coffee fruits. The material opening is inclined downward and avoids the position of the drainage component 2 to facilitate the discharge of coffee fruits. A cover plate 33 is detachably installed at the material opening of the main body 31. The cover plate 33 prevents the coffee fruits from leaking out during drying.
[0032] In a further embodiment, referring to Figure 2 The cover plate 33 and the main body 31 can form a complete cylindrical shape. The cover plate 33 is arc-shaped to ensure that it is in close contact with the top surface of the drainage component 2, so as to avoid a large amount of hot air leakage when the cover plate 33 is rotated to the position of the drainage component 2. An end shaft 34 is installed at one end of the cover plate 33, and the end shaft 34 enables the cover plate 33 to rotate around the axis. In addition, the end shaft 34 is rotatably connected to the main body 31, so that the cover plate 33 can be opened but not fall off. When discharging coffee berries, it can be used as a guide plate to ensure that the coffee berries are smoothly guided away from the main body 31 and the drainage component 2, so as to facilitate bagging in an open space. A blind hole is provided at one end of the cover plate 33 away from the end shaft 34, and a through hole is provided at the main body 31 corresponding to the blind hole. A pin rod 35 matching the blind hole is inserted in the through hole. The swing end of the cover plate 33 can be connected to the main body 31 through the detachable pin rod 35, so as to ensure stability during use, and can also be quickly disassembled for easy use.
[0033] In a further embodiment, referring to Figure 3The drainage component 2 includes a hollow frame 21, which is rectangular in shape, and the long side of the hollow frame 21 is equal to the left and right lengths of the main body 31, and the distance between the long side of the hollow frame 21 and the two end surfaces of the main body 31 is consistent. With this summary design, the air outlet 22 can fully cover the internal space of the main body 31, ensuring that all coffee fruits can be directly blown by hot air.
[0034] In a further embodiment, referring to Figure 4 The hollow frame 21 is provided with a plate 24 at the air outlet 22. The plate 24 is also long on the left and right and short on the front and back, which is compatible with the inside of the hollow frame 21 and is installed in the middle of the air outlet 22 to evenly guide the hot air and ensure that it passes through the long strip gap between the plate 24 and the inner wall of the hollow frame 21 for even air discharge. The long side length of the plate 24 is consistent with the long side length of the hollow frame 21, which can ensure that the short side of the plate 24 is fixedly connected to the inner wall of the hollow frame 21, and the middle part of the plate 24 is bent away from the main body 31, which can ensure that the airflow in the middle is guided to the front and rear sides, ensuring smooth and even wind and avoiding excessive changes in the edge of the plate 24, which may cause loud noise when the airflow passes through.
[0035] In a further embodiment, referring to Figure 4 There is a wind clearance between the long side of the plate body 1 24 and the inner wall of the hollow frame 21. The wind clearance is in a strip shape, which is convenient for the hot air to be blown into the slit 32 smoothly. Two plate bodies 25 are installed on the inner side of the hollow frame 21 above the wind clearance. The plate bodies 25 serve as guides. The two plate bodies 25 are respectively fixedly connected to the inner walls of the hollow frame 21, and the scattered hot air can be gathered to the middle. A wind clearance is formed between the bottom surface of the plate body 25 and the top surface of the plate body 1 24. A larger flow rate airflow is formed by reducing the diameter, which increases the flow rate of the hot air entering the slit 32, ensuring that the accumulated coffee cherries can be blown in smoothly and the coffee cherries are thrown up, thereby ensuring the smooth drying.
[0036] In a further embodiment, the plate body 25 is inclined, and the end of the plate body 25 close to the plate body 1 24 is bent toward the plate body 1 24 , and the concave shape of the middle part of the plate body 1 24 can carry the coffee berries and debris that fall from the slit 32 , which are first guided by the plate body 25 and then collected and received by the plate body 1 24 to avoid entering the hot air duct 1 below.
