Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a coffee fruit spin-drying and conveying machine. Background Technology

[0002] After washing, coffee cherries carry a lot of moisture on their surface and usually need to be spun dry within a specific time to ensure that the quality and flavor of the coffee beans are not affected. If they are not dried in time, the high humidity environment will cause the coffee beans to continue to ferment, which may produce unpleasant flavors or even cause the coffee beans to spoil.

[0003] Currently, there is no dedicated coffee cherry dehydrator. In existing technology, the drying of coffee cherries is usually achieved by using other types of centrifugal dryers. However, since mature coffee cherries are about 1.5-2 cm in diameter and are round or slightly oval in shape, and because the specifications of other types of dryers are not entirely suitable for drying coffee cherries, there is a problem of incomplete moisture removal in actual use. Summary of the Invention

[0004] The purpose of this invention is to provide a coffee fruit spin-drying and shoveling machine that can not only be adapted to the surface moisture spin-drying treatment of coffee fruits, but also avoid the situation of incomplete moisture spin-drying.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A coffee cherry spin dryer includes an adjustable tilt support frame and a control cabinet mounted on one side of the upper end of the support frame. The upper end of the support frame has fixed seats with arc-shaped upper ends at both the front and rear ends. Each fixed seat has several equally spaced rollers rotatably connected to its upper end. A spin dryer assembly is rotatably connected between the upper ends of two fixed seats. The spin dryer assembly includes two concentric first mesh cylinders arranged from the inside out, a second mesh cylinder rotatably connected to the first mesh cylinders, spiral blades fitted on the outer wall of the first mesh cylinders and in contact with the inner wall of the second mesh cylinders, a connecting shaft fitted on the inner wall of the first mesh cylinders with both ends extending outwards, and positioning rings respectively located at the front and rear ends of the outer wall of the second mesh cylinders. The front and rear ends of the first mesh cylinders are closed, and each positioning ring engages with the upper end of the corresponding fixed seat. A cover is fitted between the outer walls of the two fixed seats to cover the spin-drying assembly, with an opening at its lower end. An air blowing assembly is fitted over the spin-drying assembly at the upper end of the inner wall of the cover. A material conveying assembly is rotatably connected to the front end of the upper end of the support frame. A heating fan is installed at the bottom of the inner wall of the support frame. One air outlet of the heating fan is connected to the air blowing assembly through a first air outlet pipe, and the other air outlet is connected to the material conveying assembly through a second air outlet pipe. A throwing assembly is provided at the rear end of the upper end of the support frame. The second mesh cylinder is rotatably connected to the throwing assembly. A toothed ring is provided at the front end of the outer wall of the second mesh cylinder. A driving assembly for driving the first and second mesh cylinders to rotate is provided at the front end of the upper end of the support frame.

[0006] By adopting the above technical solution, when using the device, first turn on the power, operate the control cabinet, and make the drive component and heating fan work. The drive component drives the first screen cylinder and the second screen cylinder to rotate. Then, the coffee cherries to be processed are poured into the front end of the spin dryer through the feeding component. Then, the coffee cherries are conveyed backward through the gap between the first screen cylinder and the second screen cylinder by the spiral blades. The moisture on the surface of the coffee cherries is spun off by centrifugal force. At the same time, the hot air generated by the heating fan enters the spin dryer through the first air outlet pipe and the second air outlet pipe respectively, and the hot air spun off the moisture on the coffee cherries. After being spun dry, the coffee cherries are conveyed into a slinging assembly. The slinging assembly then transports the spun-dry coffee cherries outwards for easy collection and subsequent processing. If there is still residual moisture on the surface of the processed coffee cherries, the support frame is tilted so that the height of the conveying assembly is lower than that of the slinging assembly, increasing the time the coffee cherries spend in the spun-drying assembly and thus allowing the moisture to be spun out more thoroughly. During the spun-drying process, the cover prevents the water from splashing everywhere, allowing the water to flow downwards for easy handling by staff.

[0007] A further embodiment of the present invention is that the support frame includes a fixed base plate, a support column disposed opposite to one end of the fixed base plate, an electric push rod disposed opposite to the other end of the fixed base plate, a connecting seat rotatably connected to the upper ends of the support column and the electric push rod, and a support plate disposed on the upper end of the connecting seat.

[0008] By adopting the above technical solution, the tilt angle of the support plate can be flexibly controlled to control the drying of coffee cherries. By slowing down the movement speed of the coffee cherries, their time in the drying assembly can be increased. The combined effect of wind force and centrifugal force can improve the drying effect on the surface moisture of the coffee cherries.

[0009] A further feature of the present invention is that: both the front and rear ends of the upper end of the fixed base plate are provided with U-shaped fixing frames, which are used to provide support when the support plate is horizontally positioned.

[0010] By adopting the above technical solution, the force on the electric actuator is avoided when it is not working or when the support plate is working horizontally, thus extending its service life.

[0011] A further feature of the present invention is that a water guide plate is provided at the upper end of the support frame between the two fixed seats, and the water outlet of the water guide plate is inclined downward toward one side of the support frame.

[0012] By adopting the above technical solution, it is convenient to collect and process the water that falls off the coffee fruit, and place it on the water support plate to flow around.

[0013] A further provision of the present invention is that: both the front and rear ends of the upper part of the inner wall of the cover are provided with limiting components that contact the outer wall of the positioning ring and are used to fix the spin-drying assembly; the limiting components include limiting blocks with a U-shaped lower end and a plurality of limiting rollers rotatably connected to the lower end of the limiting blocks.

[0014] By adopting the above technical solution, the stability of the spin-drying component during operation can be increased, deformation of the spin-drying component caused by centrifugal force can be avoided, and the force on the connection of the fixed base can be reduced.

[0015] A further configuration of the present invention is as follows: the air blowing assembly includes two fixed air rings arranged opposite each other, a plurality of air guide tubes distributed at equal intervals between the two fixed air rings and communicating with them, and a plurality of air blowing nozzles communicating with the inner wall of the air guide tubes.

[0016] A further configuration of the present invention is as follows: the material conveying assembly includes a fixed shell with a rear opening, a material conveying hopper communicating with the upper front end of the outer wall of the fixed shell, a baffle plate arranged in a U-shape and cooperating with the front end of the inner wall of the fixed shell, and an air blowing pipe arranged at the rear end of the inner wall of the baffle plate, the air blowing pipe communicating with another air outlet of the heating fan through a second air outlet pipe.

[0017] By adopting the above technical solution, the baffle plate can not only prevent the coffee cherries from falling and piling up, but also facilitate the blowing of air from the air pipe to disperse the water on the surface of the coffee cherries, making it easier to dry them.

[0018] A further embodiment of the present invention is that the throwing assembly includes a centrifugal fan, a connecting pipe communicating with the front end of the outer wall of the centrifugal fan, a baffle plate disposed at the rear end of the outer wall of the connecting pipe, a throwing pipe communicating with the air outlet of the centrifugal fan, and a guide pipe rotatably connected to the free end of the throwing pipe.

[0019] By adopting the above technical solution, not only can the centrifugal fan generate wind to throw the dehydrated coffee cherries outward, but it can also further dry the residual moisture on the surface of the coffee cherries. Furthermore, the rotatable feed tube allows workers to collect the processed coffee cherries at any angle, improving its applicability.

[0020] A further configuration of the present invention is as follows: the drive assembly includes a mounting frame, a drive motor mounted on the upper end of the outer wall of the mounting frame, a rotating shaft rotatably connected to the lower rear end of the outer wall of the mounting frame, a gear and a first pulley mounted on the outer wall of the rotating shaft, a second pulley mounted on the outer wall of the drive motor's power output shaft, and a belt disposed between the first pulley and the second pulley.

[0021] In summary, the present invention has the following beneficial effects: Firstly, this invention can not only adapt to the surface moisture drying treatment of coffee berries, but also avoid the situation of incomplete moisture drying during the drying process. Moreover, a single drive motor can drive the first and second mesh cylinders to rotate. The cooperation between the first and second mesh cylinders can not only increase the conveying effect of coffee berries, but also increase the contact area between coffee berries and wind, thus accelerating the drying effect. Secondly, the spin-drying component of the present invention can not only prevent coffee berries from accumulating in large quantities during spin-drying, but also allow them to be conveyed in an orderly manner. At the same time, the combination of centrifugal force and wind force enhances the effect of spin-drying the surface moisture of the coffee berries. Thirdly, the support frame of the present invention can flexibly control the tilt angle of the support plate by controlling the drying of coffee cherries, thereby increasing the time the coffee cherries spend in the drying assembly by slowing down their movement speed, and improving the drying effect on the surface moisture of the coffee cherries through the combined action of wind force and centrifugal force. Fourth, the throwing component of the present invention can not only throw the dehydrated coffee cherries outward by the wind force generated by the centrifugal fan, but also further dry the residual moisture on the surface of the coffee cherries. In addition, the rotatable guide tube allows workers to collect the processed coffee cherries at any angle, improving its applicability. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] Example, refer to Figure 1-8 A coffee berry spin dryer includes an adjustable tilting support frame 1 and a control cabinet 74 mounted on one side of the upper end of the support frame 1.

The material conveying assembly 4 includes a fixed shell 41 with an open rear end, a material conveying hopper 42 that is connected to the upper part of the front end of the outer wall of the fixed shell 41, a baffle plate 43 that is U-shaped and fitted at the front end of the inner wall of the fixed shell 41, and an air blowing pipe 44 that is annular and located at the rear end of the inner wall of the baffle plate 43. The fixed shell 41 is inserted into the front end of the second mesh cylinder 22 without affecting the normal rotation of the second mesh cylinder 22.

[0031] A heating fan 45 with two air outlets is installed at the bottom of the inner wall of the support frame 1. One air outlet of the heating fan 45 is connected to the air blowing assembly 31 through the first air outlet pipe 46, and the other air outlet is connected to the air blowing pipe 44 in the material conveying assembly 4 through the second air outlet pipe 47. A throwing assembly 5 is provided at the rear end of the upper end of the support frame 1. The throwing assembly 5 includes a centrifugal fan 51, a connecting pipe 52 connected to the front end of the outer wall of the centrifugal fan 51, a baffle 53 set at the rear end of the outer wall of the connecting pipe 52, and a centrifugal fan 51. The outlet of the blower 51 is connected to the throwing pipe 54 and the guide pipe 55 which is rotatably connected to the free end of the throwing pipe 54. There is a gap between the impeller of the centrifugal blower 51 and the inner wall of its housing to facilitate the conveying of coffee berries. There is a gap between the lower end of the baffle 53 and the lower end of the connecting pipe 52 to facilitate the coffee berries reaching the bottom of the inner wall of the centrifugal blower 51 housing. The connecting pipe 52 is sleeved on the rear end of the outer wall of the second mesh cylinder 22 and rotatably connected to it. A toothed ring 26 is provided at the front end of the outer wall of the second mesh cylinder 22.

[0032] A drive assembly 6 for driving the first mesh cylinder 21 and the second mesh cylinder 22 to rotate is provided at the front end of the upper end of the support frame 1. The drive assembly 6 includes a mounting frame 61, a drive motor 62 mounted on the upper end of the outer wall of the mounting frame 61, a rotating shaft 63 rotatably connected to the lower rear end of the outer wall of the mounting frame 61, a gear 64 and a first pulley 65 mounted on the outer wall of the rotating shaft 63, a second pulley 66 mounted on the outer wall of the power output shaft of the drive motor 62, and a belt 67 that is fitted between the first pulley 65 and the second pulley 66. A pull rod is provided in the middle of the inner wall of the connecting pipe 52. The first mesh cylinder 21 is supported by a connecting shaft 24 located between the power output shaft of the drive motor 62 and the pull rod. The rotating shaft 63 is rotatably connected between the mounting frame 61 and the outer wall of the corresponding fixed seat 16. The heating fan 45, the drive motor 62 and the centrifugal fan 51 are all electrically connected to the control cabinet 74.

[0033] Usage: First, power on the device and operate the control cabinet 74 to activate the drive assembly 6 and the heating fan 45. The drive motor 62 drives the first mesh cylinder 21 to rotate via the connecting rod, and simultaneously drives the gear 64 on the rotating shaft 63 to rotate via the second pulley 66 and belt 67. The gear 64, through its meshing gear ring 26, drives the second mesh cylinder 22 to rotate. The air generated by the heating fan 45 is delivered through the first air outlet pipe 46 and the second air outlet pipe 47 to the air blowing assembly 31 and the air blowing pipe 44 of the material conveying assembly 4, thereby achieving air blowing into the material conveying assembly 4 and the spin-drying assembly 2. Then... The coffee cherries to be processed are poured into the front end of the spin dryer 2 through the feed hopper. The baffle plate 43 not only prevents the coffee cherries from piling up and falling, but also blows the airflow from the air pipe 44 to initially disperse the surface of the coffee cherries. Then, the spiral blades 23 convey the coffee cherries backward through the gap between the first screen cylinder 21 and the second screen cylinder 22. The moisture on the surface of the coffee cherries is shaken off by the combination of centrifugal force and wind force. As the first screen cylinder 21 and the second screen cylinder 22 rotate, the conveying effect of the coffee cherries is accelerated, and they can also rotate in the spiral blades 23 to increase the contact area with the flowing air.

[0034] After being spun dry, the coffee cherries are conveyed into the throwing assembly 5. The baffle 53 not only prevents the coffee cherries from contacting the impeller of the centrifugal fan 51, but also allows the coffee cherries to reach the bottom of the inner wall of the centrifugal fan 51. This facilitates the blowing of the coffee cherries towards the throwing pipe 54 by the air generated by the centrifugal fan 51. The air generated by the centrifugal fan 51 then transports the spun-dry coffee cherries out through the throwing pipe 54 for easy collection and subsequent processing. The guide pipe 55 can be flexibly adjusted according to the worker's position and the tilt angle of the support plate 15. If there is still residual moisture on the surface of the processed coffee cherries, the support frame 1 can be tilted so that the height of the conveying assembly is lower than the height of the throwing assembly 5, increasing the time the coffee cherries spend in the spun-drying assembly 2, thus making the moisture more thoroughly spun dry. During spun-drying, the cover 3 prevents the water from splashing everywhere, making it easy for the water guide plate 73 to collect the water and facilitate worker handling.

[0035] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make inventive modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
