Description

Technical Field

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

[0002] After fermenting and washing the coffee beans, the main purpose of drying is to remove excess moisture from the beans. The moisture content of the green beans usually needs to be reduced to between 10% and 12% to prevent mold and spoilage while maintaining the flavor and quality of the coffee beans.

[0003] For example, the coffee bean processing drying device disclosed in Authorization Publication No. CN212754178U includes a base with a drying box fixedly connected to the base, a cover plate movably connected to the top of the drying box, and a support plate fixedly connected to the interior of the drying box. The support plate has a plurality of air holes, the top openings of which are smaller than the size of the coffee beans. By adopting this technical solution, the beneficial effects of this utility model are: the coffee beans are dried by heating with an electric heating plate and blowing air with a fan driven by a first motor, which is unaffected by weather conditions and has higher drying efficiency.

[0004] Although the above patent is not affected by weather conditions and has higher drying efficiency, the moisture in the coffee beans will evaporate into water vapor during drying. The above device is not equipped with a structure to remove water vapor, so the water vapor will accumulate in the equipment and cannot be effectively discharged, which may affect the drying efficiency. Utility Model Content

[0005] The purpose of the present invention is to provide a drying device for coffee bean processing to solve the problems raised in the above background technology.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. A drying device for processing coffee beans is used in conjunction with an air pump, a cooling box, a cold water pipe, a drain pipe and an exhaust pipe. During drying, moisture in the coffee beans is evaporated by high-temperature air. While drying at high temperature, the air pump inside the shell is started. After the air pump is started, water vapor is sent into the cooling box. At the same time, cooling water circulates in the cold water pipe. The cooling water absorbs the heat of the water vapor and is recycled, and the water vapor is condensed and discharged from the drain pipe. In this way, during drying, water vapor can be prevented from flowing back into the drying box, which affects the drying efficiency.

[0018] 2. This kind of drying device for processing coffee beans is used in conjunction with an inner frame, a ceramic support plate, an electric push rod, movable block one, movable block two and a lower hopper. During the drying process, the motor is started, and the motor drives the vibration block to rotate. When the vibration block rotates, the inner frame vibrates. The coffee beans inside the inner frame are vibrated, which can increase the contact area with the high-temperature air, thereby improving the drying efficiency. After drying, the electric push rod is started, and the electric push rod controls the ceramic support plate close to the lower hopper to flip downward, so that the coffee beans on the ceramic support plate slide into the lower hopper and are discharged, thereby achieving the purpose of facilitating and quickly unloading.

[0028] In this embodiment, during processing, coffee beans to be dried are placed into the inner frame 3 through the feeding port 17, and the electric heating tube 16 is started. The electric heating tube 16 heats the air inside the drying box 1, and the high-temperature air evaporates the moisture in the coffee beans. Simultaneously with the high-temperature drying, the air pump 5 inside the outer shell 2 is started. After the air pump 5 is started, the water vapor is sent to the cooling box 6. At the same time, cooling water circulates in the cold water pipe 7. The cooling water absorbs the heat of the water vapor and is then recycled. The water vapor is condensed and discharged from the drain pipe 8. In this way, during drying, the water vapor can be prevented from flowing back into the drying box 1, thereby affecting the drying efficiency.

[0030] In this embodiment, during the drying process, the motor 10 is started, and the motor 10 drives the vibration block 11 to rotate. When the vibration block 11 rotates, it vibrates the inner frame 3. The coffee beans inside the inner frame 3 are vibrated, which can increase the contact area with the high-temperature air, thereby improving the drying efficiency. After drying, the electric push rod 14 is started, and the electric push rod 14 controls the ceramic support plate 4 to flip downward at one end close to the lower hopper 15, so that the coffee beans on the ceramic support plate 4 slide into the lower hopper 15 and are discharged, thereby achieving the purpose of facilitating and quickly unloading.

[0031] Working principle: During processing, the coffee beans to be dried are placed into the inner frame 3 from the feeding port 17, and the electric heating tube 16 is started. The electric heating tube 16 heats the air inside the drying box 1, and the moisture in the coffee beans is evaporated by the high-temperature air. While drying at high temperature, the air pump 5 inside the outer shell 2 is started. After the air pump 5 is started, the water vapor is sent to the cooling box 6. At the same time, cooling water circulates in the cold water pipe 7. The cooling water absorbs the heat of the water vapor and is recycled, and the water vapor is condensed and discharged from the drain pipe 8. In this way, during drying, the water vapor can be prevented from flowing back into the drying box 1, which affects the drying efficiency. During the drying process, the motor 10 is started, and the motor 10 drives the vibration block 11 to rotate. When the vibration block 11 rotates, the inner frame 3 is vibrated. The coffee beans inside the inner frame 3 are vibrated, which can increase the contact area with the high-temperature air, thereby improving the drying efficiency. After drying, the electric push rod 14 is started, and the electric push rod 14 controls the ceramic support plate 4 close to the lower hopper 15 to flip downward, so that the coffee beans on the ceramic support plate 4 slide into the lower hopper 15 and are discharged.
