Description

Technical Field

[0001] The utility model belongs to the technical field of spray drying, in particular to a sprayer used for drying vitamins. Background Art

[0002] The drying process of vitamins is a common step in pharmaceutical and food additive production. It is crucial for ensuring the stability, solubility, and bioavailability of vitamins. Vitamins can be dried using a variety of methods, including spray drying, freeze drying, vacuum drying, and fluidized bed drying. Spray drying involves atomizing a dilute material (such as a solution, emulsion, or suspension) into tiny droplets through an atomizer. These droplets are then exposed to hot air, rapidly vaporizing the water in the droplets to produce a dry product. Due to its advantages such as high speed, continuous production, and excellent overall performance, this method is widely used in the material drying industry. However, in the actual production process of vitamin thermal spray drying, uneven droplet atomization and poor dispersion lead to vitamin decomposition and heat-sensitive loss during the drying process, seriously affecting production efficiency.

When these droplets come into contact with the hot air, the moisture in the wall material evaporates rapidly, solidifying the wall material and thus enveloping the heartwood.
