[0002] As one of the three major beverages in the world, the coffee we drink daily is made from coffee beans and various cooking utensils. Coffee beans refer to the kernels inside the fruit of the coffee tree, which are then roasted using appropriate methods. They taste bitter. After the raw coffee beans are picked from the coffee tree, they first need to go through multiple processing steps such as peeling, degumming, grading and screening, drying, storage, shelling, polishing, etc., and then after roasting, they become the raw coffee beans we can buy on the market.

[0003] Please refer to the drying device for coffee processing with announcement number CN220369446U. This patent provides a toggle mechanism inside the drying device to toggle and tumble a large amount of coffee beans, thereby improving the overall drying efficiency. A collection component is also provided inside to facilitate the rapid collection of the dried coffee beans, thereby improving the collection efficiency of the coffee beans and reducing manual operations.

[0004] However, although the above patent can realize the drying of coffee beans and the collection of dried coffee beans, the collection box for collecting coffee beans is blocked by the sealing plate during the drying process, and the finger hole for opening the sealing plate is located deep in the dried coffee beans. Therefore, when it is necessary to open the sealing plate to collect the coffee beans, it is difficult to operate the sealing plate, and the high temperature of the residual coffee beans can easily burn the operator. In addition, in order not to block the heating tube, the volume of the collection box is not too large. Therefore, the collection box can only collect a limited number of coffee beans, which can easily lead to the inability of the coffee bean drying device to dry a large number of coffee beans. In view of this, the present application proposes a small-grain coffee processing raw material dryer. Utility Model Content

An air outlet pipe 10 extending into the interior of the hot air blower 4 is provided at the bottom of the hot air box 6, facilitating the downward flow of air driven by the rotation of the fan blade 8 and heating the air by the electric heating wire 9.

[0027] Among them, a sealing gasket 11 slidably adapted to the air outlet pipe 10 is fixedly connected to the inner side of the limiting cylinder 401, facilitating the prevention of hot air from flowing upward through the gap between the air outlet pipe 10 and the limiting cylinder 401 by the provided sealing gasket 11.

[0030] The beneficial effects of the above embodiments are as follows:

[0031] For this small - grain coffee processing raw material dryer, hot air can be delivered to the hot air blower 4 through the heating assembly, and the hot air blower 4 can deliver hot air to the coffee beans in the drying cylinder 1 through the micro air holes inside it. Combining with the turning effect of the turning blades 5 and the lever 12 on the outer side of the hot air blower 4 during rotation, the contact efficiency between the coffee beans and the hot air can be effectively improved, thereby realizing the uniform heating of the coffee beans and effectively improving the drying efficiency.

[0032] And after drying is completed, the baffle 13 can be pulled outwards to open the material dropping openings 201 on the fixing plate 2, facilitating the downward movement of the dried coffee beans through the material dropping openings 201, so as to discharge the drying cylinder 1, making it convenient to collect the dried coffee beans.

[0033] The working principle of the above embodiment is:

[0034] When using the dryer for processing raw materials of small-grain coffee, the baffle 13 needs to be pushed into the drying cylinder 1 first, and the rotating limit plate 15 is made to resist the side of the operating plate 14 away from the baffle 13, so that the baffle 13 covers the drop opening 201 on the fixed plate 2; then the feeding pipe 17 can be used to put the coffee beans to be dried into the drying cylinder 1;

[0035] After that, the rotary motor 7 can be operated to drive the fan blades 8 to rotate, so as to drive the air in the hot air box 6 to flow downward, and the arranged electric heating wire 9 can heat the air in the hot air box 6, so as to achieve the effect of producing hot air, and make the hot air flow to the hot air cylinder 4 through the air outlet pipe 10, and the hot air entering the hot air cylinder 4 can flow outward evenly through the micro air holes arranged inside the hot air cylinder 4, so as to facilitate the heating of the coffee beans in the drying cylinder 1;

[0036] During this process, the rotating motor 3 can also be operated to drive the hot air cylinder 4 to rotate, so that the coffee beans can be turned by the rotation of the turning blades 5 and the lever 12, thereby effectively improving the contact efficiency between the coffee beans and the hot air, thereby achieving uniform heating of the coffee beans and enhancing the drying efficiency of the coffee beans;

[0037] When the coffee beans are dried, the limiting plate 15 can be rotated to offset the operating plate 14. At this time, the baffle 13 can be pulled out to open the drop opening 201 on the fixed plate 2, so that the dried coffee beans can flow downward. The collection operation of the dried coffee beans can be achieved by simply providing a receiving structure at the bottom of the drying cylinder 1.
