Abstract
An air-lift dryer for processing a high-lactose aqueous fluid (HLAF), such as permeate from ultrafiltration of whey fluid, is provided. The air-lift dryer has an enclosed drying chamber with diverging interior sidewalls that define an intermediate interior space having a cross-sectional area that increases as the diverging interior sidewalls extend away from a lower portion toward an upper portion.
Claims3
An air-lift dryer, comprising:
- an enclosed drying chamber having an atomizing inlet for introducing atomized partially crystallized high-lactose aqueous fluid into the enclosed drying chamber;
- the enclosed drying chamber also including an upper portion and a lower portion, a primary air inlet and an exhaust air outlet;
- the atomizing inlet and the primary air inlet located in the lower portion, the enclosed drying chamber having upwardly diverging interior sidewalls defining an intermediate interior space having a cross-sectional area that increases as the diverging interior sidewalls extend away from the lower portion toward the upper portion.
