Description

Technical Field

[0001] This utility model relates to the field of cocoa production and processing technology, and in particular to a cocoa shell and flesh separator. Background Technology

[0002] The fruit of the cocoa tree is a drupe, oval or oblong in shape, initially pale green, later turning deep yellow or nearly red. The fruit contains many seeds, flattened seeds of an oblong nut. The cocoa butter extracted from it has a unique aroma and melting properties.

[0003] Cocoa beans can be separated from their kernels through shell breaking and separation. For example, Chinese Patent Publication No. CN205865898U discloses a cocoa bean shelling device, belonging to the field of agricultural crop shelling technology. It includes a feeding mechanism, a shell breaking mechanism, a vibrating screen, and a shell suction machine. The feeding mechanism includes a conveyor belt with several hoppers. The shell breaking mechanism includes a shell and several shell breaking rollers. The shell breaking rollers are rack and pinion type. The vibrating screen is sloped. The shell suction machine includes several suction ports and bellows connecting the suction ports, with a fan and a shell outlet connected to the bellows. The suction ports are evenly arranged, and the distance between each suction port and the vibrating screen is the same. Its advantages are: thorough shell breaking and kernel separation, while improving the screening rate of cocoa bean shells and kernels and reducing losses.

[0004] In practice, plump cocoa fruits usually mean that they contain more nutrients and have greater commercial value. Some separation equipment cannot screen cocoa fruits of different sizes after separating the shell and flesh. Because of the different sizes of the cocoa fruits, some cocoa fruits cannot be processed effectively, which may lead to waste of raw materials. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cocoa shell and meat separator, including a frame, a shell breaking mechanism is provided at the top of the frame at the feed inlet, and a vibrating screen and a negative pressure device are respectively provided inside the frame below and next to the shell breaking mechanism.

[0008] The machine frame has a discharge port on the discharge side of the vibrating screen, and several pairs of screening rods are located at the discharge port. The spacing between a pair of screening rods is adjusted by a fixing component to screen cocoa beans of different particle sizes.

[0009] Furthermore, the fixing component includes a limiting block, the frame is provided with an inclined surface at the discharge port, and the screening rod is rotatably connected to the inclined surface by a number of pairs of T-shaped rods, and the top of one of the adjacent T-shaped rods is slidably connected to the limiting block through a limiting part.

[0010] Furthermore, a spring is sleeved around the T-shaped rod, with both ends of the spring abutting against the limiting block and the top protrusion of the T-shaped rod, respectively.

[0011] Furthermore, the screening rod has several limiting grooves distributed around its circumference at one end of the through hole, and the limiting block engages with the limiting grooves through the limiting protrusion at the bottom.

[0012] Furthermore, it also includes a rotating component and a double-ended screw. A guide groove is provided on the opposite side between the pair of screening rods, and the rotating component is rotatably connected to the other end of the pair via a groove. The rotating components on both sides are threadedly connected to the two ends of the double-ended screw.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A cocoa shell and meat separator includes a frame 1, a shell breaking mechanism 2 is provided at the top of the frame 1 at the feed inlet, and a vibrating screen 3 and a negative pressure device 4 are respectively provided inside the frame 1 below and next to the shell breaking mechanism 2.

[0024] The frame 1 has a discharge port on the discharge side of the vibrating screen 3, and several pairs of screening rods 5 are located at the discharge port. The spacing between a pair of screening rods 5 is adjusted by a fixing component 6 to screen cocoa beans of different particle sizes.

[0025] In some embodiments, the shell-breaking mechanism 2 consists of several sets of synchronously rotating shell-breaking rollers. After the dried cocoa fruit is shelled by the shell-breaking mechanism 2, the vibrating screen 3 conveys the shell and fruit through the vibration generated by the guide plate and the vibrating motor. On the other hand, the vibration makes the shell and fruit tumble, which facilitates the negative pressure device 4 to absorb and separate the shell.

[0026] Specifically, the surface of the guide plate is also provided with deceleration protrusions, which slow down the conveying speed of the shell and the fruit, thereby further improving the separation efficiency of the shell.

[0027] Furthermore, the fixing component 6 includes a limiting block 61, the frame 1 has an inclined surface at the discharge port, and the screening rod 5 is rotatably connected to the inclined surface by several pairs of T-shaped rods 62, and the top of one of the adjacent T-shaped rods 62 is slidably connected to the limiting block 61 by a limiting part 63.

[0028] It should be added that the limiting part 63 includes a limiting groove and a limiting rod. The limiting block is disposed on the periphery of the T-shaped rod 62, and the limiting groove is disposed in the central through hole of the limiting block 61. The limiting groove and the limiting block are slidably connected, and the limiting block 61 is circumferentially locked in sequence, so that the limiting block 61 achieves the function of fixing the screening rod 5 under the action of the spring 64.

[0029] Furthermore, a spring 64 is sleeved around the T-shaped rod 62, with both ends of the spring 64 abutting against the limiting block 61 and the top protrusion of the T-shaped rod 62, respectively.

[0030] More specifically, the screening rod 5 has several limiting grooves 65 distributed around its circumference at one end through hole, and the limiting block 61 is engaged with the limiting grooves 65 by the limiting protrusion at the bottom.

[0031] It is worth mentioning that one end of a pair of screening rods 5 is rotatably connected to a T-shaped rod 62, and the other end is adjusted in distance from a pair of rotating parts 66 to a double-headed screw 67. Therefore, if the ends of the screening rods 5 cannot be locked when the pair of screening rods 5 are rotatably connected to the rotating parts 66, they will swing randomly.

[0032] Specifically, the spacing between the ends of a pair of screening rods 5 away from the T-shaped rod 62 is adjusted. As the spacing gradually decreases, the size of the cocoa fruit particles being screened also gradually decreases.

[0033] In general, it also includes a rotating component 66 and a double-ended screw 67. A guide groove 51 is provided between the pair of screening rods 5 on opposite sides, and the rotating component 66 is rotatably connected to the other end of the rods 5 through a groove. The rotating components 66 on both sides are threadedly connected to the two ends of the double-ended screw 67 respectively.

[0034] Finally, the vibrating screen 3 is rotatably connected to a baffle 31 on the side of the discharge port. The baffle 31 is positioned above the limiting block 61. The end face of the baffle 31 is provided with a guide 32 between two adjacent sets of screening rods 5. The guide 32 has an inverted triangular structure.

[0035] In specific operation, the baffle 31 is set above the limiting block 61, so that the baffle 31 can cooperate with the guide 32 to allow the cocoa fruit to pass over the limiting block 61 and be directly transported through the guide trough 51.

[0036] Specifically, by setting the guide 32, the fruit can be prevented from being discharged from the frame 1 along the large gap between two adjacent sets of screening rods 5.

[0037] Working method: During operation, the dried cocoa fruit is poured into the shell-breaking mechanism 2 from the feed port of the frame 1 for shell-breaking processing. The shelled cocoa fruit and cocoa fruit enter the vibrating screen 3 for conveying. During the conveying process, the cocoa fruit and cocoa fruit are tumbled by vibration, and the negative pressure device 4 cleans the fruit shell.

[0038] Then, according to the size of the fruit to be screened, the distance between the ends of a pair of screening rods 5 is adjusted. The limiting block 61 is pulled upward and slids. When the limiting protrusion is disengaged from the limiting groove 65, the double-headed screw 67 is rotated and the rotating parts 66 on both sides slide along the double-headed screw 67 to achieve the function of relative movement to adjust the distance between a pair of screening rods 5. After that, under the action of the spring 64, the limiting protrusion of the limiting block 61 is inserted into the limiting groove 65 to fix the screening rods 5.

[0039] Finally, the fruit enters the feed trough 51 through the baffle 31 and guide 32, and slides along the feed trough 51 under the gravity of the inclined plane, so that fruits of different particle sizes fall at different positions on the screening rod 5 for screening.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
