3.1 Yield of banana milk powder
The yield of banana milk powder is affected by the type of the dryer, the feed pump speed used and the blend
feed ratio of milk banana proportion. Loss of product in a spray dryer may occurred during drying due to the
sticking of the particle solution around the drying chamber. Figure 2 shows the product produced using freeze
drying at 1:3 proportion. Dried powder cannot be produced using freeze dry at this proportion since most of the
product was freeze at the wall of the flask. This may be due to high solid content of the liquid mixture being used to
dry in the freeze dryer
