New Way of Drying Shrimp Feed
In a modern shrimp feed pelleting process increasingly more liquids are
added into the mash feed. This in combination with long-term steam
conditioning is increasing gelatinization and water stability for better
end-product quality. Recipe cost optimization can be limited if there
are drying capacity restrictions. In a lot of situations, moisture
removal with only cooling is not enough anymore and an extra drying step
is required. Moisture control is more and more crucial for quality and
cost price reasons.
In traditional shrimp feed processing, there is a separate machine for
drying and cooling, the products are dropped from the pellets mill/post
conditioner into the dryer for moisture removal, then into the cooler to
cool down the product with ambient air. Moisture control is done by
checking the product after the dryer and corrections by measurements of
finished product moistures. The process is shown in figure 1.
