Description

Technical Field

[0001] The utility model relates to the field of feed additive material drying and processing, in particular to a spray drying system. Background Art

[0002] Spray drying is a common method for drying materials at present. The material can contact with hot air in the drying chamber, so that the moisture in the material can be vaporized, thereby realizing the drying of the material. Since spray drying can directly dry the material into a powdery or granular product, spray drying is often used in the production and processing of feed additives.

[0003] However, in actual processing, on the one hand, before the material enters the spray drying, its moisture content may be too high, and it is impossible to effectively dry it sufficiently only by spray drying. In addition, after spray drying, the material may still have too high moisture content after spray drying. At this time, the material is likely to adhere to various structures of the drying system, which is not only not conducive to the collection of the material, but also likely to cause damage to other structures.

[0004] On the other hand, the material after spray drying may contain more gases such as water vapor, and it is difficult to ensure that the purity of the material meets the requirements. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a spray drying system, which can solve one or more of the above problems.

Moreover, the present utility model is also provided with a cyclone separation device, which can facilitate the solid-liquid separation of the materials processed by the spray drying device, avoid the retention of water vapor, etc. in the materials, improve the purity of the finally obtained materials, and the separated gas can be discharged through the exhaust fan, while the materials can be collected through the bag dust removal device.
