Description

Technical Field

[0001] This utility model relates to the field of coffee degumming technology, and in particular to a coffee fruit degumming machine. Background Technology

[0002] In China, coffee processing typically employs a wet process. This process removes residual sugars and gums from the surface of the coffee beans after peeling. Fermentation involves soaking the peeled coffee beans in a pool of water to dilute the surface sugars and gums, then stirring, removing them, and drying them to obtain dried coffee beans. In the primary processing of coffee, the removal of gums from the fresh coffee cherries is a crucial step in improving the quality of the finished product; its efficiency and precision directly impact the subsequent fermentation and drying processes.

[0003] However, most existing coffee cherry degumming machines use a single scraper or stirring blade structure, which cannot completely cover and remove the gum layer from different parts of the fruit, resulting in inconsistent degumming levels and affecting the consistency of the finished product. Furthermore, existing coffee cherry degumming machines do not take into account the structural strength of the device during use, making their service life and stability during use less than ideal. Therefore, a coffee cherry degumming machine is provided to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coffee fruit degumming machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coffee fruit degumming machine, comprising a fruit degumming box, wherein a feed inlet is provided at the bottom of one end of the fruit degumming box, a discharge outlet is provided at the top of the other end of the fruit degumming box, a sieve frame is provided inside the fruit degumming box, several support rods are provided on the outer circumference of the sieve frame, a degumming component is provided inside the sieve frame, a switch door is provided on one side of the fruit degumming box, and a transmission box is provided on the top of the fruit degumming box.

[0006] As a further description of the above technical solution: the fresh fruit degumming box includes a box body disposed at the bottom of the transmission box, a base frame disposed at the bottom of the box body, an mounting plate disposed at the inner bottom of the box body, a feeding frame disposed at the top of the mounting plate and connected to the feeding port, a limiting plate disposed at the top of the feeding frame and cooperating with the screen frame, a discharge frame disposed at the inner top of the box body and connected to the discharge port, a water supply pipe disposed on one side of the discharge frame, and the top center of the box body... The equipment is equipped with a transmission hole that mates with the transmission box. The top of the box has several docking holes. A base frame is provided at the bottom of the box to enhance the stability of the equipment. The mounting plate, feeding frame, and limiting plate standardize the internal structure and facilitate component replacement. The limiting plate prevents the screen frame from shifting, improving transmission and screening accuracy. The discharge frame and water pipe collect the degummed coffee cherries in the discharge frame and rinse them with water pipe to improve the degumming effect and keep them clean and prevent clogging.

[0007] As a further description of the above technical solution: the screen frame includes an annular screen plate disposed on the top of the limiting plate. A plurality of screen holes are provided on one side of the annular screen plate. A plurality of mounting frames are provided in the middle of the annular screen plate, and the mounting frames cooperate with the support rods. Sleeve rings are provided at the top and bottom of the annular screen plate. Through the arrangement of the annular screen plate and screen holes, the annular structure of the annular screen plate ensures that the material can be evenly distributed on the screen mesh. The arrangement of the screen holes improves the material throughput and effectively removes adhesive residues. The sleeve rings at the top and bottom enhance the rigidity and fit of the screen frame, preventing shaking. Simultaneously, the cooperation between the mounting frames and the support rods strengthens the rigid support force of the annular screen plate during use, improving stability during degumming.

[0008] As a further description of the above technical solution: the degumming assembly includes a transmission rod inserted inside the feed frame. Several auxiliary rods and an inclined plate are arranged on the outer circumference of the transmission rod, and the inclined plate cooperates with the annular screen. A spiral plate is arranged at the bottom of the transmission rod, and the spiral plate cooperates with the feed frame. By setting the transmission rod to pass through the feed frame, it provides a propulsive force for the degumming of fresh coffee cherries, and drives the operation of the entire degumming system. The cooperation of the auxiliary rods and the inclined plate utilizes the inclined plate to tumble and scrape the material on the screen, destroying the pectin structure of the fresh coffee cherries. The auxiliary rods enhance the stirring effect and improve the uniformity of degumming. The spiral plate is responsible for pushing the material from the bottom to the upper discharge port to achieve continuous propulsion.

[0009] As a further description of the above technical solution: a drive motor is installed inside the transmission box. The rotating shaft of the drive motor is matched with the transmission hole, and the drive motor is connected to the transmission rod. Several support frames are provided at the bottom of the transmission box. The support frames are connected to the docking holes by bolts. By setting the linkage of the drive motor, transmission hole and transmission rod, the drive motor's rotating shaft transmits force to the transmission rod through the transmission hole to adjust the speed and force, adapting to different coffee cherries' viscosity. The support frames are connected to the docking holes by bolts, which stabilizes the transmission box. The bolted connection allows for quick replacement or maintenance of the transmission box.

[0010] This utility model has the following beneficial effects:

[0011] This invention relates to a coffee cherry degumming machine, which combines a base frame and a mounting plate. The base frame reinforces the overall equipment's shock resistance during operation, while the mounting plate standardizes the installation of internal components, facilitating future replacement and maintenance. The support rod and limiting plate work together to prevent the screen frame from shifting during operation, avoiding misalignment of the annular screen and resulting in screening failure. The combination of the support rod and mounting frame enhances the overall rigidity of the screen, making the equipment more stable and extending its lifespan. A continuous drive chain is formed by a transmission motor, transmission holes, transmission rods, and a spiral plate. The transmission motor adjusts the power output to handle coffee cherries with varying viscosity. The transmission rod not only propels the material but also drives the entire stirring system. With the combined action of the auxiliary rod and the inclined plate, a triple effect of scraping, tumbling, and stirring is achieved, greatly enhancing the degumming ability. The spiral plate ensures that the coffee cherries are fed from the bottom upwards, making the degumming process continuous and preventing accumulation.

[0012] This invention relates to a coffee cherry degumming machine. By incorporating an annular screen, the material is ensured to be evenly distributed on the screen, preventing concentrated accumulation. Screen holes improve sieving efficiency and prevent gum residue. A ring reinforces the vertical rigidity of the annular screen, preventing vibration-induced detachment or positional shift. The combination of the discharge frame and water pipe allows for centralized discharge of degummed coffee cherries, facilitating subsequent collection or further processing. The water pipe directly rinses the discharge port and the cherries, preventing gum residue and improving equipment cleanliness and thorough degumming. Furthermore, the transmission box support frame is connected to the mating holes via bolts, allowing for quick disassembly, replacement, or maintenance of the transmission box.

A water pipe 17 is provided on one side of the discharge frame 16, which can be flushed with water during operation and discharged in conjunction with the screen holes 42. After the degumming process is completed, the material is discharged through the discharge port 3 located at the other end of the top of the box 11. At the same time, the support frame 82 at the bottom of the transmission box 8 is connected to the docking hole 19 at the top of the box 11 by bolts, realizing the stable assembly of the power system and the structural box. The transmission motor 81 is also equipped with a wireless controller, which can flexibly adjust the speed and torque according to the gum thickness and moisture state of different varieties of coffee cherries, improving the adaptability and control accuracy of the system.
