AI Technical Summary
The lack of a dedicated treatment device for coffee roasting fumes in existing technologies means that conventional air filtration equipment cannot effectively handle grease, dust, and coffee flakes.
A coffee bean roasting flue gas treatment device was designed, comprising a heater, an air purifier, and a cooler. The heater treats the flue gas at high temperature to vaporize the oils and coffee skin, a three-way catalytic converter purifies the gas, and finally the cooler cools and discharges the gas.
It effectively purifies the smoke from roasting coffee beans, removing oils and coffee skin, and reducing the taste and temperature of the emitted gases.

Abstract
Description
Technical Field
[0001] This utility model relates to a device for treating coffee bean roasting flue gas. Background Technology
[0002] Fresh coffee beans need to be roasted using a coffee roaster. After roasting, the beans are ground and extracted to obtain coffee liquid. The roasting process produces a large amount of fumes containing oils, dust, and coffee skin. These fumes need to be treated before being released. However, there are currently no air treatment devices on the market specifically designed to treat coffee roasting fumes, so conventional air filtration equipment fails to effectively remove the oils from these fumes.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a coffee bean roasting flue gas treatment device that can treat the flue gas generated during coffee bean roasting before discharging it.
[0005] To achieve the above objectives, this utility model provides a coffee bean roasting fume treatment device, which includes a heater, an air purifier, and a cooler disposed inside the body. The body is provided with an air inlet and an air outlet. The air inlet is connected to the input end of the heater, the output end of the heater is connected to the input end of the air purifier, the output end of the air purifier is connected to the input end of the cooler, and the output end of the cooler is connected to the air outlet.
[0006] In one or more embodiments, the heater includes a housing, a ceramic core, and a heating wire. The ceramic core is disposed inside the housing, and multiple through-holes are distributed on the ceramic core. The heating wire is arranged in a circuitous manner on the multiple air channels, and there are gaps between the heating wire and the air channels for gas to pass through.
[0007] In one or more embodiments, the air purifier is a three-way catalytic converter, and the output end of the heater is connected to the output end of the air purifier by a flange.
[0008] In one or more embodiments, the interior of the machine body defines an upper region and a lower region, with the heater and air purifier disposed in the upper region and the cooler disposed in the lower region. The air purifier and the cooler are connected by a fan casing, which is vertically arranged.
[0009] In one or more embodiments, the cooler includes a radiator and a cooling fan. The radiator has an air inlet and an air outlet. The air inlet is connected to the output of an air purifier, and the air outlet is connected to an air outlet. The cooling fan is located on one side of the radiator.
[0010] In one or more embodiments, an exhaust fan is provided on the air outlet.
[0011] Compared with the prior art, the advantages of this utility model are: the input flue gas is treated at high temperature by the heater, and the grease, dust and coffee coating are rapidly vaporized in the high temperature environment. Then, the gas is deodorized by the air purifier and finally cooled down by the cooler before being discharged directly. Attached Figure Description

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0016] See appendix Figure 1-3 This application provides a coffee bean roasting fume treatment device, which includes a heater 2, an air purifier 3, and a cooler 4 disposed inside a body 1. The body 1 is provided with an air inlet 5 and an air outlet 6. The air inlet is used to allow the fume generated by the coffee roaster to enter. The air inlet 5 is connected to the input end of the heater 2, the output end of the heater 2 is connected to the input end of the air purifier 3, the output end of the air purifier 3 is connected to the input end of the cooler 4, and the output end of the cooler 4 is connected to the air outlet 6. When the fume enters the heater, the high temperature of the heater will burn the oils and coffee coat in the fume, causing them to vaporize. Then, the air purifier will purify the odor in the fume, and finally, the fume will be directly discharged after being cooled by the cooler. This treatment device can effectively purify the fume generated from roasting coffee beans.
[0017] The heater 2 includes a housing 21, a ceramic core 22, and a heating wire 23. The ceramic core 22 is located inside the housing 21 and has multiple air channels 7 that run through it. The heating wire 23 is arranged in a meandering manner on the multiple air channels 7. There is a gap between the heating wire 23 and the air channels 7 that allows gas to pass through. The heating wire heats the ceramic core, so that the flue gas passing through is heated quickly.
[0018] The air purifier 3 is a three-way catalytic converter. The output end of the heater 2 is connected to the output end of the air purifier by a flange 8 to ensure a tight connection between the heater and the air purifier.
[0019] The body 1 is divided into an upper region and a lower region. The heater 2 and the air purifier 3 are located in the upper region, and the cooler 4 is located in the lower region. The air purifier 3 and the cooler 4 are connected by a fan shell 9, which is vertically arranged. The upper and lower regions can prevent the heat from the heater from radiating to the cooler.
[0020] The cooler 4 includes a radiator 41 and a cooling fan 42. The radiator has an air inlet and an air outlet. The air inlet is connected to the output end of the air purifier 3, and the air outlet is connected to the air outlet 6. The cooling fan 42 is located on one side of the radiator 41. During the process of air passing through the radiator, the radiator can exchange heat with the air, thereby reducing the temperature of the exhaust air. The cooling fan can dissipate heat and cool the radiator.
[0021] An exhaust fan 10 is provided on the air outlet 6, which can guide the air inside the cooler to be discharged.
[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
