Loss-In-Weight Feeding In Fish Food Production

The production of quality fish food for a wide range of species requires a number of factors to be taken into consideration, such as: density, water stability, nutritional composition (recovery of essential amino acids and vitamins) and digestibility. Actual fish pellet density, for example, is critical when manufacturing fish food pellets for specific types of fish, such as bottom tank feeders versus those that tend to feed from the top of the tank.

In such critical applications the efficiency and accuracy of the ingredient feeding system is crucial to meeting the criteria for each formulation. The use of K-Tron Loss-in-Weight (LIW) feeders featuring the highly accurate K-Tron SFT load cell technology is ideal for meeting the variety of criteria in fish food extrusion and pelletization. In addition, the minimalization of ingredient loss by providing exact accountability of ingredients fed, provides the manufacturer with maximum process profitability.
