Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean equipment, in particular to a coffee bean stirring device. Background Art

[0002] Coffee beans refer to the fruit of the plant used to make coffee. The coffee fruit is composed of two oval seeds facing each other, and the connecting side is flat, which is called flat beans. But there are also beans composed of one round seed, which are called round beans. The taste of the beans is no different. The beans have different tastes depending on the growing areas. The factors affecting the taste are the variety of coffee trees, the nature of the soil where they grow, the climate and altitude of the cultivation garden, the caution of picking the fruits, and the process of bean processing. Coffee is a beverage made from roasted and ground coffee beans. As one of the three major beverages in the world, it is the same as cocoa and tea as the main beverages popular in the world.

[0042] An extension column 12 is provided at one end of the fixed column 11 away from the positioning column 9. The outer side of the extension column 12 is also rotatably connected to the cooling scraper 13. The inner side of the extension column 12 is rotatably connected to the synchronous shaft 21, and the synchronous shaft 21 is fixed to the corresponding cooling scraper 13, so that the rotation of the synchronous shaft 21 can drive the corresponding cooling scraper 13 to rotate at the same time. For details, please refer to Fig. 9 In the figure, the center position of the cooling scraper 13 and the fixed column 11 is the position for the rotating shaft 10 to pass through, and the center position of the extension column 12 is the position for the synchronization shaft 21 to pass through. The synchronization shaft 21 is slidably connected with the rotating shaft 10, so that the synchronization shaft 21 can translate and slide inside the rotating shaft 10, and the rotation of the rotating shaft 10 can drive the synchronization shaft 21 to rotate synchronously. The outer side of the adjacent end of the fixed column 11 and the extension column 12 is threadedly connected with an adjusting sleeve 22, so that the rotation of the adjusting sleeve 22 drives the fixed column 11 and the extension column 12 to move towards or away from each other. The outer side of the adjusting sleeve 22 is evenly fixed with anti-slip bumps, which makes it easy to drive the adjusting sleeve 22 to rotate.

[0043] The use process of a coffee bean stirring device provided by the utility model is as follows: when the coffee beans enter the interior of the heating and stirring barrel 3 through the feeding barrel 2 for heating and roasting, and enter the interior of the cooling barrel 5 for cooling after heating and roasting, the heated coffee beans are located at the top of the filter plate in the cooling barrel 5 at this time, and the rotating column 8 is driven to rotate by the operation of the stepping motor, and the rotation of the rotating column 8 drives the positioning column 9 to rotate synchronously through the synchronous plate 14, so that the rotation of the positioning column 9 drives the corresponding cooling scraper 13 to rotate through the fixed column 11, and then the coffee beans on the top of the filter plate are stirred and cooled by the rotation of multiple cooling scrapers 13, and at the same time, according to the different diameters of the filter plate, the adjusting sleeve 22 can be rotated, so that the rotation of the adjusting sleeve 22 drives the threaded extension column 12 to move away from the fixed column 11, and at the same time, the synchronous shaft 21 inside the extension column 12 is extended and slid inside the rotating shaft 10, so that the position of the extension column 12 and the cooling scraper 13 on the extension column 12 can be adjusted as needed;

[0044] When it is necessary to rotate the cooling scraper 13 to adjust the angle between the cooling scraper 13 and the filter plate to adapt to the cooling of coffee beans of different thicknesses, the positioning column 9 is pulled to allow the stepper motor to drive the rotation of the rotating column 8, so that the synchronous plate 14 at the bottom of the positioning column 9 is located at the center of the synchronous groove. At this time, the positioning column 9 is pulled to allow the positioning column 9 to rise and drive the synchronous plate 14 to disengage from the inside of the synchronous groove. When the synchronous plate 14 disengages from the synchronous groove of the sliding connection, the bottom of the transmission bevel gear 19 contacts the bottom end of the inside of the positioning column 9. At this time, the stepper motor drives the rotation of the rotating column 8, allowing the rotating column 8 to pass through the synchronous groove. The block 16 drives the support column 18 and the transmission bevel gear 19 to rotate, so that the rotation of the transmission bevel gear 19 drives the multiple adjustment bevel gears 20 to rotate, and the rotation of the adjustment bevel gear 20 drives the corresponding rotating shaft 10 to rotate, so that the rotation of the rotating shaft 10 drives the corresponding cooling scraper 13 to rotate, so that the multiple cooling scrapers 13 are adjusted at the same time. The angle between the cooling scraper 13 and the filter plate is smaller, the more suitable it is for cooling less coffee beans on the filter plate, and the larger the angle between the cooling scraper 13 and the filter plate, the more suitable it is for cooling thicker coffee beans on the filter plate.
