Description

Technical Field

[0001] The invention relates to the technical field of powder flavor drying, in particular to a powder flavor spray drying device. Background Art

[0002] Powdered flavors, also known as solid flavors, are generally used in solid soups, solid beverages, and other powdered foods. Flavors, also known as blended spices, are a mixture of various spices that are artificially blended in appropriate proportions with natural or artificial spices. Powdered flavors are extremely prone to hydrolysis reactions when not dried, causing certain components in the flavors to hydrolyze due to the influence of pH, which in turn affects the stability of the flavor and causes the powdered flavor to lose its effectiveness. Currently, spray drying is one of the methods of applying systematic technology to material drying. It is usually used to atomize the thin material in a drying chamber, and then the water vaporizes rapidly in contact with hot air to obtain a dry product.

[0003] Therefore, how to fully dry the powder flavor automatically and improve the quality of the powder flavor is a technical problem that the current technicians need to solve. At the same time, during the use of the existing drying device, since there is no stirring blade inside the drying device, the flavor powder is deposited to the bottom of the drying tower without being completely dry, resulting in a large amount of moisture in the produced flavor powder, which affects the quality of the flavor powder. At the same time, since the hot air is introduced into the inner cavity of the drying tower from a fixed pipe, there is a certain temperature difference in the hot air in the inner cavity of the drying tower, resulting in the moisture in the flavor powder continuing to evaporate due to heat, which further causes the heating of the flavor powder to be not very uniform, further affecting the quality of the flavor powder. The outlet end of the ventilation duct of the existing powder flavor spray drying device is mostly directly arranged in the inner cavity of the drying tower. In this state, the hot air has only a fixed outlet; resulting in a certain temperature difference in the hot air in the drying tower, which affects the heating condition of the powder flavor. At the same time, when the device is in use, the flavor powder accumulated on the jet nozzle will cause the jet nozzle to be blocked during use.

[0004] For example, the Chinese utility model patent with publication number "CN220939122U" and name "A powder flavor spray drying device" solves the problem of "how to quickly evaporate the droplets after spraying". Specifically, it uses hot air to form a high-speed airflow through a small tube mouth. The negative pressure generated drives the liquid to be sprayed onto the obstacle, and splashes around under high-speed impact to turn the droplets into mist particles and spray out from the nozzle; the mist droplets sprayed from the nozzle will dry quickly, and compared with the separate spray drying mode, it dries faster and more thoroughly; however, as to how to ensure the quality of the powder flavor under the condition of rapid drying, this technical solution cannot guarantee the quality of the finished product.
