Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a coffee bean roasting device. Background Technology

[0002] Freshly picked coffee cherries need to be washed, peeled, and processed before they can be made into coffee beans. After peeling and sorting, the coffee beans need to be roasted. Roasting is a crucial step in determining coffee quality, and the most important aspect is ensuring the beans are thoroughly roasted, both inside and out. Current coffee roasting equipment typically places a fixed number of coffee beans into the roasting apparatus for roasting. This is a static process, and because of the large number of beans, uneven heating can easily occur, leading to some beans being overheated and scorched, thus affecting the quality of the coffee beans.

[0003] To address the aforementioned issues, a utility model patent with authorization announcement number CN212937840U discloses a balanced coffee bean roasting device. This device, through a vibration device and an upper and lower roasting structure, enables the coffee beans to be roasted evenly on both the upper and lower sides, effectively preventing the coffee beans from being overheated and burnt in certain areas.

[0004] However, in actual use, the device cannot utilize the waste heat generated during baking, resulting in energy waste and failing to meet the energy-saving requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a coffee bean roasting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coffee bean roasting apparatus includes a roasting chamber with a lid on its left side, a discharge pipe at the lower right end of the roasting chamber, and a feeding box at the upper end of the roasting chamber, which is connected to the roasting chamber via the feeding pipe. An end cap is installed on the left side of the feeding box. A drying mechanism is located on the left side of the roasting chamber for supplying hot air into the roasting chamber. A dispersing mechanism is located on the left side of the lid for stirring the coffee beans in the roasting chamber and the feeding box.

[0008] As a preferred embodiment, the drying mechanism includes a drying chamber with several electric heating tubes distributed inside it. A drying tube is also installed on the drying chamber, with the other end of the drying tube penetrating the chamber cover and communicating with the baking chamber. A drying pump is also installed on the drying tube.

[0009] As a preferred embodiment, the baking oven is also equipped with a circulation pipe, the other end of which is connected to the feeding box. The feeding box is also equipped with a return pipe, the other end of which is connected to the dehumidification box on the drying oven. The dehumidification box is connected to the drying oven through an auxiliary pipe.

[0010] As a preferred embodiment, a dehumidification box is inserted into the dehumidification box.

[0011] As a preferred embodiment, the dispersing mechanism includes a dispersing component for dispersing coffee beans in the roasting oven and a stirring component for dispersing coffee beans in the feeding box.

[0012] As a preferred embodiment, the dispersion assembly includes a dispersion rotating shaft rotatably mounted on a box cover, a spiral dispersion paddle mounted on the dispersion rotating shaft, a dispersion seat mounted on the left side of the box cover, and a dispersion motor mounted on the dispersion seat for driving the dispersion rotating shaft to rotate.

[0013] As a preferred embodiment, the stirring assembly includes a stirring shaft rotatably mounted on the end cover, a stirring paddle mounted on the stirring shaft, a first dispersing pulley mounted on the dispersing shaft, a second dispersing pulley mounted on the stirring shaft, and a dispersing belt fitted between the first dispersing pulley and the second dispersing pulley.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: The air inside the drying chamber is heated by an electric heating element, and then the hot air is delivered to the roasting chamber by a drying pump to dry the coffee beans inside. Subsequently, the hot air enters the feeding box through a circulation pipe, pre-drying the coffee beans there. This allows for the secondary utilization of the heat source, reducing energy waste and better meeting energy-saving requirements. This invention has a reasonable structure and can reuse the residual heat from roasting, effectively reducing energy waste and better meeting energy-saving needs. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example: Please refer to Figures 1-4 A coffee bean roasting apparatus includes: a roasting chamber 1, a chamber cover 11 installed on the left side of the roasting chamber 1, a discharge pipe 12 provided at the lower right end of the roasting chamber 1, and a feeding box 13 installed at the upper end of the roasting chamber 1. The feeding box 13 and the roasting chamber 1 are connected by a feeding pipe. Both the discharge pipe 12 and the feeding pipe are equipped with solenoid valves. An end cap 14 is installed on the left side of the feeding box 13; a drying mechanism 3, located on the left side of the roasting chamber 1, for supplying hot air into the roasting chamber 1; and a dispersing mechanism 2, installed on the left side of the chamber cover 11, for stirring the coffee beans in the roasting chamber 1 and the feeding box 13. In this embodiment, a feeding hopper 15 is provided on the feeding box 13, and a detachable hopper cover is provided at the upper end of the feeding hopper 15.

[0022] The working principle of this utility model is as follows: In specific use, coffee beans with drying are added to the roasting oven 1, while coffee beans to be dried are stored in the feeding box 13. Then, the coffee beans are dried by the drying mechanism 3. At the same time, the dispersing mechanism disperses the coffee beans to improve the drying effect, speed up the drying efficiency, and effectively reduce energy waste.

[0023] As a further embodiment, the drying mechanism 3 includes a drying chamber 31, in which several electric heating tubes are distributed and installed. A drying tube 32 is also installed on the drying chamber 31, with the other end of the drying tube 32 penetrating through the chamber cover 11 and communicating with the baking chamber 1. A drying pump 33 is also installed on the drying tube 32. A circulation pipe 34 is also installed on the baking chamber 1, with the other end of the circulation pipe 34 communicating with the feeding box 13. A return pipe 35 is also installed on the feeding box 13, with the other end of the return pipe 35 communicating with the dehumidification box 37 on the drying chamber 31. The dehumidification box 37 is connected to the drying chamber 31 through an auxiliary pipe 36.

[0024] The working principle of the drying mechanism 3 is as follows: During drying, the air in the drying chamber 31 is heated by an electric heating tube. Then, the hot air is delivered to the roasting chamber 1 by the drying pump 33 to dry the coffee beans in the roasting chamber 1. Subsequently, the hot air enters the feeding box 13 through the circulation pipe 34 to pre-dry the coffee beans in the feeding box 13. This enables the secondary utilization of the heat source, reduces energy waste, and better meets the energy-saving requirements. Then, the hot air enters the dehumidification box 37 through the return pipe 35, and finally returns to the drying chamber 31 through the auxiliary pipe 36.

[0025] As a further embodiment, a dehumidification box 38 is inserted into the dehumidification box 37. In this embodiment, the dehumidification box 38 contains a desiccant for drying the return air.

[0026] As a further embodiment, the dispersing mechanism 2 includes a dispersing component for dispersing coffee beans in the roasting oven 1 and a stirring component for dispersing coffee beans in the feeding box 13. The dispersing component includes a dispersing rotating shaft 22 rotatably mounted on the box cover 11, a spiral dispersing paddle 23 mounted on the dispersing rotating shaft 22, a dispersing seat 21 mounted on the left side of the box cover 11, and a dispersing motor 24 for driving the dispersing rotating shaft 22 to rotate mounted on the dispersing seat 21. The stirring component includes a stirring rotating shaft 28 rotatably mounted on the end cover 14, a stirring paddle 29 mounted on the stirring rotating shaft 28, a first dispersing pulley 25 mounted on the dispersing rotating shaft 22, a second dispersing pulley 26 mounted on the stirring rotating shaft 28, and a dispersing belt 27 fitted between the first dispersing pulley 25 and the second dispersing pulley 26.

[0027] The working principle of the dispersing mechanism 2 is as follows: During dispersing, the dispersing motor 24 is started, which drives the dispersing rotating shaft 22 to rotate, thereby realizing the rotation of the spiral dispersing paddle 23. This disperses the coffee beans in the roasting box 1, improving the drying effect. After drying, the spiral dispersing paddle 23 can transport the coffee beans to the discharge pipe 12 for easy discharge. At the same time as the dispersing rotating shaft 22 rotates, it drives the first dispersing pulley 25 to rotate. Through the dispersing belt 27, the second dispersing pulley 26 rotates, which in turn drives the stirring rotating shaft 28 to rotate. This causes the stirring paddle 29 on the stirring rotating shaft 28 to move the coffee beans in the feeding box 13, improving their pre-drying effect.
