Big Capacity 1.8-2 T/H Aquatic Fish Feed Extruder Machine For
Medium Fish Farm
Introduction of Dry Type Fish Feed Extruder Machine
Food for fishes always contains rich crude protein, but the crude
protein in the food is hard to digest for the fish. After being
processed by the fish feed pellet extruder, the feed can be easy to
digest. Similar with wet type fish feed extruder, dry type also
uses alloy steel. Dry type fish feed extruder is suitable for
small- or medium-scale fish farms and fish feed industry, for
processing shrimp feed, prawn feed, floating fish feed, sinking
fish feed pellets and pet feed pellet.
Features of Dry Type Fish Feed Machine
1. This fish feed machine adopts the auto-controlling speed feeding
tool to produce the feed material evenly.
2. Electric heating device is adopted which can improve the feed
expansion rate and pellets floating time.
3. High temperature and high pressure cooking process can kill the
salmonellosis and bacterial infections and also makes the pellets
easily to digest.
4. The cutting knife adopts the frequency controlling speed in
order to change the material size.
5. The floating time can be controlled by the puffing degree
adjustment.
6. Auto-temperature control system makes the temperature
controlling more direct viewing and the parameter more precise.
Common Raw Material for Making Nutritional Fish Feed
☆ Rice Dust: contain about 10-14% of protein and also contain
vitamin B1, B2, B6 and small quantity of enzyme.
☆ Mustard Cake: Mix maximum 40% of cake in the fish feed. But don’t
use dry cake more than 20%. Mustard cake contain 30-32% protein. It
also contain a high rate of fat.
☆ Wheat Chaff: contain fiber, control many types of fish diseases.
☆ Maize: contain protein, carbohydrate, fat, vitamin A and E.
☆ Cotton Seeds: contain about 54% protein. It is a better
ingredients for supplementary fish feed.
☆ Fish Powder: easily digestible to fish. Fishmeal contain about
55-60% protein.
☆ Bone Powder: very necessary for building fish-bone. The ratio of
calcium and magnesium in the bone dust is 2 : 1.
☆ Innards : very suitable and ideal feed for catfish. It contain
52% protein.
