Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying machines, in particular to a rapid drying machine for fresh coffee fruits. Background Art
[0002] As one of the three major beverages in the world, coffee is becoming more and more popular, and it is gradually associated with fashion and modern life. During the processing of coffee beans, the raw coffee beans need to be dried. The color of coffee beans varies from light to dark. Through deep roasting, the coffee beans burst open, the volume doubles, and the weight decreases by nearly 1 / 4. Volatile flavor oils are gradually generated during the roasting process, so that various flavors achieve a perfect balance.
[0003] When drying fresh coffee fruits, the existing dryers usually use a heating structure to heat the air to form hot air, and blow the hot air to the fresh coffee fruits to dry them. For example, Chinese patent publication number CN214047513U discloses "a double-heating rolling coffee fruit quick-drying dryer", which uses solar hot air from the inside to the outside to dry, and infrared rays from the inside to the outside to assist, accelerate drying, dry quickly, save time, and shorten the processing process of 5-10 days to within 7-8 hours. In the production process, water vapor is heated and evaporated, and there is no other unnecessary smoke, dust and other pollutants, so it is truly clean and environmentally friendly.
[0004] However, in actual use, since the hot air blown out by the fan is not guided, a large part of the hot air blows to different corners of the chassis, causing the chassis to absorb a large amount of heat, resulting in a slow heating process of the coffee beans, which cannot be heated quickly, and causing a large heat loss of the equipment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A quick dryer for fresh coffee fruit is designed, comprising a chassis with a feed inlet and a discharge port and a drum with air holes, the drum is rotatably arranged in the chassis, a heating device is arranged on one side of the chassis, a heat conduction pipe is connected to the output end of the heating device, the other end of the heat conduction pipe passes through the chassis, a fan matched with the heat conduction pipe is arranged in the chassis, an air outlet is arranged at the upper end of the fan, a guide cover matched with the drum is fixedly arranged in the chassis, an adjustment plate matched with the fan and the guide cover is arranged in the chassis, and a partition matched with the heat conduction pipe is also arranged in the chassis.

[0011] Furthermore, far-infrared heating tubes matching the partition and the drum are arranged at intervals in the chassis, and the far-infrared heating tubes are equipped with graphene heating strips.
[0012] Furthermore, the discharge port is provided with a door shaft rotatably connected to the chassis, and a baffle matching the discharge port is fixedly provided on the door shaft.

[0013] Furthermore, a PLC control device is provided on the chassis, and the PLC control device is electrically connected to the heating device and the fan. A temperature sensor electrically connected to the PLC control device is provided in the chassis.
[0014] The utility model provides a quick drying machine for fresh coffee fruit, which has the following beneficial effects:
[0015] In the utility model, the hot air blown out by the fan is concentratedly guided to the drum part by setting the guide cover and the adjustment plate to heat the coffee beans in the drum, thereby reducing the diffused hot air, so that the hot air with a higher temperature blown out by the fan can contact the drum to the maximum extent, and flow between the drum and the guide cover as the drum rotates, so that most of the heat in the new hot air is directly transferred to the fresh coffee fruits;
[0016] Secondly, in the utility model, by controlling the angle of the adjustment plate, the flow direction of the hot air is adjusted. When the hot air blown out by the fan has a large power, the adjustment plate can be moved close to the inner wall of the chassis to prevent the hot air from deviating from the deflector cover and being unable to be guided by the deflector cover.
