How To Make Catfish Feed Pellets Fish Feed Machine On Sale
Zhengzhou Fusmar Machinery is a professional fish feed pellet machine manufacturer, this article we will introduce the way of making catfish feed in detail. There are a lot of farmers choose to breed catfish, because it is relatively strong adaptability, and the growth rate is fast and mature is relatively fast, so it means that there is a higher economic benefit, but in the process of breeding catfish must pay attention to the principle of feed selection and feed feeding technology.
How To Make Catfish Feed
Catfish feed is a floating fish feed, is a feed processing technology. In fact, the puffing of the feed in the extrusion chamber is a high temperature instantaneous process, that is, the feed is in the environment of high temperature, high pressure, high shear force and high moisture. The feed mill equipment price is reasonable by Zhengzhou Fusmar Machinery provided.
Raw materials need to be crushed and expanded, and then dried after the expansion pelletization, and finally the surface spray oil waterproof. Then through continuous mixing, conditioning, heating, pressurization, curing, extrusion die hole and sudden pressure reduction to form a leavened porous feed.
Generally, the floating fish feed machine is used for pelletizing. The raw material is extruded and pushed by the screw in the extruder to produce high temperature and high pressure. At the moment of passing through the die hole, the temperature and pressure drop sharply, making the water in the raw material evaporate rapidly, the volume expands, and the specific gravity becomes lighter.
Finally, it is cooled and dried to room temperature and less than 12% moisture. Puffing fish feed can float in water due to its specific gravity.
How To Increase Catfish Capacity
- Pond selection. The pool bottom should choose less silt, adequate water source, convenient injection and drainage, water quality is good, the pond base is firm and watertight, no pesticide pollution of the pool culture.
- Reasonable breeding. Just arrived fish fry, weak resistance, and different specifications. If directly put into the big pond breeding, because the fish fry activity range, physical consumption, and the input of feed is difficult to eat, resulting in a waste, but also pollution of water quality. However, if the implementation of two levels of seedlings, that is, the first concentrated in the small pond intensive care, and then put into the big pond breeding. This is not only easy to manage, but also make the fish fry better adapt to the new environment, and easy to get enough food in the small pond, promote its rapid growth.
- Feeding reasonably. Catfish is omnivorous fish, so correct grasp the amount of food, do the pond how much fish to feed, prevent blind casting bait. In the first month of the lower pond, the feed was...
