¿Qué es la harina de pescado?

Fishmeal is a brown powder rich in protein and nutrients, which is commonly used in the production of animal feeds, such as cat and dog food, rabbit food, and poultry feed. It is mainly made from some fish that are not suitable for human consumption, small fish, dead fish or fish processing residues (e.g., fish head, fish bones, viscera, etc.) after cutting, steaming, pressing, drying, and other processes.

Due to the high nutritional value and market demand, fish meal production has become a very promising business in recent years.

How to make fish meal with the fish meal production line?

The common fish meal processing procedure includes fish cutting→fish cooking→cooked fish squeezing→steam drying→fish powder cooling screening→fish meal grinding→fish meal packaging. During the fish squeezing, the fish oil is made. See if you need a fish oil separator.

Applications of fish meal production line

1. Para elaborar alimento para el ganado. La harina de pescado se puede utilizar para el procesamiento de piensos para el ganado. Se utiliza principalmente para la producción de piensos para animales como cerdos, pollos y ganado vacuno. El alimento para estos animales debe contener proteínas de alta calidad, especialmente para cerdos y pollos jóvenes. Debido a que los animales jóvenes se encuentran en un período de crecimiento vigoroso, la demanda de proteínas y la proporción de aminoácidos en las proteínas son relativamente altas. La harina de pescado es una proteína animal en la que la proporción de aminoácidos es la más cercana a la que necesitan los animales.
2. Piensos para animales acuáticos. La harina de pescado en polvo se utiliza como materia prima principal para las proteínas alimentarias, como pescado, cangrejos y camarones, en animales acuáticos. La proporción de aminoácidos necesarios para la harina de pescado y los animales acuáticos es la más cercana. Agregar harina de pescado puede garantizar que los animales acuáticos crezcan más rápido.
3. Se utiliza para elaborar piensos para animales de peletería. El polvo de pescado se puede utilizar para preparar alimento para algunos animales con pelaje, como zorros y grillos. Los animales de peletería son en su mayoría carnívoros y la demanda de proteínas es grande en crecimiento. La harina de pescado de alta calidad como materia prima proteica es la primera opción para estos ingredientes de alimentación animal.
