Description

Technical Field

[0001] This utility model relates to the field of food processing machinery, and in particular to a quantitative feeding device for a coffee roaster. Background Technology

[0002] In the coffee roasting process, the precision and automation of the feeding process directly affect the roasting quality and production efficiency.

[0003] Current coffee roaster feeding methods primarily rely on manual operation, which has several significant drawbacks: First, manual feeding makes it difficult to precisely control the amount of coffee beans added, leading to fluctuations in the amount of material fed each time, resulting in unstable roasting quality and failing to meet standardized production requirements. Second, manual feeding requires a large amount of manpower and is limited by operating speed, making it difficult to match the pace of modern large-scale roasting production lines and increasing enterprise labor costs. Third, traditional devices lack an effective airflow control structure; the airflow generated by the blower during operation can easily backflow into the feed hopper, causing material splashing and inaccurate weighing, resulting in material waste and affecting the equipment's metering accuracy. To address the aforementioned problems of large errors, low automation, and airflow backflow interference in manual feeding, a quantitative feeding device for coffee roasters is proposed. Utility Model Content

[0006] Preferably, the feeding pipe includes a three-way pipe body that is fixedly connected between the coffee bean metering feeding mechanism and the connecting pipe head by two sets of hexagonal bolts in the upper and rear flanges, a rotating rod that is rotatably installed in the through hole at the upper end of the three-way pipe body, and a windproof thin plate that is rotatably sleeved on the rotating rod and branched into the three-way pipe body.

[0007] Preferably, the windbreak plate is not perpendicular to the inner wall of the branch pipe in the closed state of the three-way pipe body, and the horizontal tilt angle is sixty degrees.

[0009] Preferably, a perforated bent pad is welded and installed on the lower surface of the blower.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-5 As shown in the figure, a quantitative feeding device for a coffee roaster in this embodiment includes a feeding hopper support frame 1. A coffee bean feeding hopper 2 is fixedly installed inside the feeding hopper support frame 1. A control box 3 is welded to one side of the coffee bean feeding hopper 2. A coffee bean quantitative feeding mechanism 4 is fixedly connected to the lower flange of the coffee bean feeding hopper 2 by a set of hexagonal bolts. A feeding mechanism controller 5 is welded to one corner of the coffee bean quantitative feeding mechanism 4. A feeding pipe 6 is fixedly connected to the lower flange of the coffee bean quantitative feeding mechanism 4 by a set of hexagonal bolts. A connecting pipe head 7 is fixedly connected to the rear flange of the feeding pipe 6 by a set of hexagonal bolts. A blower 8 is fixedly connected to the rear end of the connecting pipe head 7 by screws.

[0023] Specifically, this quantitative feeding device, through its integrated design of precise quantitative feeding, automated conveying, and anti-backflow control, solves the problems of inaccurate measurement, low manual efficiency, and airflow interference in traditional feeding methods. It improves the stability and standardization of roasting production while reducing labor costs and material waste. Specifically, the quantitative feeding of coffee beans is achieved through the vibration and weighing structure of the quantitative feeding mechanism 4, realizing precise measurement of coffee beans, avoiding errors from manual feeding, and ensuring consistent material quantity for each roasting, laying the foundation for stable roasting quality. Automated feeding and conveying combines the airflow conveying of the blower 8 with the structural design of the feeding pipe 6 to achieve automated transfer of coffee beans from the storage hopper to the roaster, reducing manual intervention and improving production efficiency. Anti-backflow and airflow control are crucial for the feeding process. The baffle plate 603 inside pipe 6 automatically closes the upper branch pipe during air blowing, preventing airflow from impacting the quantitative feeding mechanism 4 and the feed hopper 2 at a 60-degree angle, thus avoiding material splashing or weighing inaccuracies. The feed hopper support frame 1 supports and fixes the coffee bean feed hopper 2, ensuring the structural stability of the entire feeding device. The coffee bean feed hopper 2 stores coffee beans to be roasted, providing a material source for the quantitative feeding mechanism. The control box 3 contains electrical components used to control the operation of the entire quantitative feeding device. The coffee bean quantitative feeding mechanism 4 achieves quantitative output of coffee beans through its internal vibrating feeding structure and weighing structure, ensuring accurate material quantity fed into the roaster each time. The feeding mechanism controller 5 controls the operation of the coffee bean quantitative feeding mechanism 4 in real time, adjusting the feeding speed and quantitative parameters.

[0024] See appendix Figure 1-4 As shown, the feeding pipe 6 includes a three-way pipe body 601 fixedly connected between the coffee bean metering feeding mechanism 4 and the connecting pipe head 7 by two sets of hexagonal bolts in the upper and rear flanges, a rotating rod 602 rotatably installed in the through hole at the upper end of the three-way pipe body 601, and a windproof thin plate 603 rotatably sleeved on the rotating rod 602 and in the branch pipe on the three-way pipe body 601.

[0025] The windbreak plate 603 is not perpendicular to its inner wall when it is closed inside the branch pipe of the three-way pipe body 601, and the horizontal tilt angle is sixty degrees.

[0026] Specifically, the three-way pipe body 601 connects the quantitative feeding mechanism 4 and the blower 8 to form a material conveying channel. Its upper branch pipe receives a quantitative amount of coffee beans, and its rear end is connected to the blower. The rotating rod 602 supports the wind baffle plate 603 and makes it rotatable, controlling the opening and closing of the branch pipe. When the blower 8 is working, the wind baffle plate 603 rotates to close the upper branch pipe of the three-way pipe body 601, and fits against the inner wall at a horizontal tilt angle of 60 degrees to prevent the airflow from blowing back into the quantitative feeding mechanism 4 and the feed hopper 2, thus avoiding affecting the subsequent discharge accuracy.

[0027] See appendix Figure 1As shown, a square perforated gasket is welded and fixed to the lower end of the feed hopper support frame 1.

[0028] Specifically, a square perforated gasket is welded to the lower end of the feed hopper support frame 1, which can be fixed to the equipment base or workbench with bolts to enhance the installation stability;

[0029] See appendix Figure 1 As shown, a perforated bent pad is welded and installed on the lower surface of the blower 8.

[0030] The blower 8 has a fan rotation direction and a blower direction on its surface.

[0031] Specifically, the connecting pipe head 7 connects the feeding pipe 6 and the blower 8 to ensure smooth airflow. It is also fixed with flanges and bolts to ensure sealing. The blower 8 blows air into the three-way pipe body 601 through the connecting pipe head 7, forming airflow power to transport a fixed amount of coffee beans along the feeding pipe 6 to the roaster. A perforated bent pad is welded to the lower surface to fix the blower and prevent it from vibrating and shifting during operation. The fan rotation direction and the blowing direction are marked on the surface to facilitate confirmation of the airflow direction during installation and ensure conveying efficiency. The perforated bent pad welded to the lower surface of the blower 8 fixes the blower 8 in a suitable position to prevent it from vibrating and shifting during operation. The front end of the three-way pipe body 601 is connected to the conveying pipe of the roaster by bolts and flanges.

[0032] During initial preparation, turn on the feeding mechanism controller 5, and set the feeding speed and quantitative parameters of the coffee bean quantitative feeding mechanism 4 according to the roasting production requirements to ensure that the amount of material fed into the roaster each time is accurate. Add the coffee beans to be roasted into the coffee bean feed hopper 2 to ensure that the coffee bean storage is sufficient to meet the production requirements for a certain period of time.

[0033] During the feeding operation, turn on the power switch of the control box 3 to start the control system of the entire quantitative feeding device, so that each component enters the operating state. Start the coffee bean quantitative feeding mechanism 4 through the feeding mechanism controller 5. The internal vibration feeding structure and weighing structure start working. According to the set quantitative parameters, the coffee beans are accurately measured and conveyed to the upper branch pipe of the three-way pipe body 601 of the feeding pipe 6. Start the blower 8. The blower 8 blows air into the three-way pipe body 601 through the connecting pipe head 7 to form airflow power. At this time, the wind baffle 603 rotates at a horizontal tilt angle of 60 degrees under the action of airflow to close the upper branch pipe of the three-way pipe body 601, and fits against the inner wall to prevent the airflow from blowing back into the quantitative feeding mechanism 4 and the feeding hopper 2, so as to avoid affecting the subsequent discharge accuracy. At the same time, the quantitative coffee beans are conveyed to the roaster along the feeding pipe 6 under the push of the airflow.

[0034] When the feeding process is finished, or when the coffee bean storage in the coffee bean feed hopper 2 is insufficient, first turn off the coffee bean metering feeding mechanism 4 to stop the metering of coffee beans; then turn off the blower 8 to stop the airflow and complete the feeding operation.

[0035] The operation process of this utility model is as follows: When installing and fixing, align the square perforated shim at the lower end of the feed hopper support frame 1 with the corresponding hole on the equipment base or workbench, use bolts to pass through the hole of the shim and the corresponding hole, and tighten the bolts to ensure that the feed hopper support frame 1 is installed firmly and provides stable support for the entire feeding device.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
