Description

Technical Field

[0001] The utility model belongs to the technical field of drying devices, and in particular relates to a sucralose airflow drying device. Background Art

[0002] Sucralose, as a high-sweetness, low-calorie sweetener, has been widely used in the food processing field due to its excellent stability and safety. In its production process, drying is a key step to ensure product quality and efficiency. However, the currently commonly used sucralose drying equipment, such as fluidized bed dryers and spray dryers, although they meet production needs to a certain extent, still have many shortcomings.

[0003] Although the fluidized bed dryer can effectively dry the materials, its thermal efficiency is relatively low, resulting in high energy consumption, which is not conducive to the energy conservation, emission reduction and cost control of the enterprise. Although the spray dryer has high drying efficiency, it has large equipment investment, complex operation, and high technical requirements for operators, which increases the operating cost and labor cost of the enterprise.

[0004] In addition, if the solid waste residues such as gangue generated during the production of sucralose are not cleaned up in time, they will not only occupy production space and affect production efficiency, but may also have an adverse effect on product quality. At present, there are two main ways to clean up waste residues: manual cleaning and mechanical cleaning. Although the manual cleaning method is flexible, it is inefficient and labor-intensive, which is not conducive to the long-term operation of the enterprise. Mechanical cleaning methods, such as using gangue rakes, can significantly improve the cleaning efficiency, but most of the existing gangue rakes use mechanical transmission, which has a complex structure and high maintenance cost, and is prone to dust generation during the cleaning process, causing environmental pollution.

[0005] Therefore, developing a new type of equipment that can not only efficiently dry sucralose, but also effectively clean up the waste residue generated during the production process, while reducing energy consumption and environmental pollution has become an urgent problem for current sucralose production companies to solve. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the above-mentioned defects of the prior art and provide a sucralose airflow drying device, which has the advantages of high thermal efficiency, low energy consumption, small equipment investment, simple operation, high efficiency in cleaning waste residues, and no pollution.

The centrifuge is connected to the airflow dryer, and the airflow dryer is connected to the pulverizer. The airflow dryer includes a drying box, an airflow system, and a slag rake device. The slag rake device includes a slag rake shaft, and the slag rake shaft is arranged inside the drying box. A rake bucket is fixedly connected to the slag rake shaft, and the airflow system is connected to the body of the drying box. The drying box is a cylindrical structure with a drying chamber inside. A feed port is provided at the top of the drying chamber, and a discharge port is provided at the bottom.

[0008] Preferably, a speed reducer is arranged on the shaft of the scraper, the shaft of the scraper is connected to a driving sprocket, a driving chain is arranged on the driving sprocket, and the driving chain is connected to a driving motor.

[0013] Preferably, the heat exchanger is also provided with an air outlet and an air inlet.

[0014] Preferably, the air inlet is connected to a filter, and the filter is connected to a fan. The filter is used to filter impurities in the air. The heat exchanger is used to heat the air. Under the action of the fan, the air is filtered by the filter, enters the heat exchanger for heating, and then enters the drying chamber from the bottom of the drying box to dry the sucralose.

[0015] Preferably, the rake bucket is in an arc shape, and its front end is a toothed structure. The rake bucket is arranged in the drying chamber for cleaning the waste residue. The rake bucket is in an arc shape, and its front end is provided with a toothed structure, so as to better clean the waste residue. The drive chain connects the rake machine shaft and the drive sprocket, and the drive sprocket is driven by a drive motor. The drive motor is connected to the drive sprocket through a reducer to reduce the rotation speed and increase the torque.

[0016] The sucralose airflow drying device described in the utility model, when working, first, starts the driving motor, and the motor drives the sprocket to rotate through the reducer. The driving sprocket drives the rake shaft to rotate through the driving chain, and then the rake bucket fixedly connected to the rake shaft moves inside the drying box. Then the sucralose to be dried is added into the drying chamber through the feed port at the top of the drying box. At the same time, the fan is started, and the air is sucked in by the fan and filtered for impurities through the filter. The filtered air enters the heat exchanger, and the air is heated by the steam introduced by the steam inlet. The heated air is discharged through the air outlet and enters the drying chamber from the bottom of the drying box to dry the sucralose. The waste gas or moisture generated during the drying process is discharged through the air outlet provided on the drying box. During the drying process, the rake bucket moves continuously in the drying chamber, and the design of its arc and toothed structure helps to better clean the waste residue generated during the drying process. The waste residue is discharged through the discharge port at the bottom of the drying box. When the sucralose in the drying chamber reaches a predetermined drying degree, the fan, the driving motor and other equipment are turned off. The dried sucralose is discharged through the discharge port at the bottom of the drying box, completing the entire drying process. The dried sucralose can be further crushed.
