Description

Technical Field

[0001] The present application relates to the technical field of drying devices, and in particular to a centrifugal spray drying device for solid beverages. Background Art

[0002] When solid beverages are produced and processed, the raw materials in liquid state are dried by a centrifugal spray drying device to form a powdered solid beverage. The centrifugal spray drying device plays an important role in the production of solid beverages.

[0003] The Chinese patent with announcement number CN218357396U discloses a centrifugal spray drying device, including a drying tower, a feed pipe installed inside the drying tower, a ventilation pipe fixedly installed on the outer wall of the drying tower, and three connecting pipes that penetrate the drying tower and extend to the inside of the drying tower are connected to the outer wall of the ventilation pipe. The other ends of the three connecting pipes are connected to the drying pipe located below the feed pipe, and the bottom of the drying tower is connected to the discharge pipe. After the liquid feed is dried using the drying tower, the dried material falls along the feed pipe to the discharge pipe. In this process, by starting the hot air blower, multiple nozzles are used to spray hot air flow, and the material is further dried to achieve the effect of fully drying the material. Then the fully dried material falls on the filter plate through the discharge pipe, and the large and small particles of the material can be screened, so as to facilitate the classification and collection of the large and small particles in the material.

[0004] The above-mentioned centrifugal spray drying device atomizes and dries the liquid raw material through a collecting pipe, a centrifugal atomizer and a hot air pipe, and then dries it again through the hot air sprayed from the drying pipe and the nozzle. The mist material sprayed from the collecting pipe is often concentrated, so that the hot air sprayed from the drying pipe and the nozzle cannot contact the material evenly over a large area, resulting in a poor secondary drying effect on the material.
