Apr1. Different meanings:
1. Maturation: refers to the process of feed from raw to cooked. Since the feed is also cooked during the extruding process, the extruded feed can also be called matured feed.(visit the http://limafeedmachine.com/products/fish-feed-machine/ to learn the fish feed extruder)
2. Extruded pellet feed: a new technology for feed processing, the extrusion of feed in the extrusion cavity is actually a high-temperature instantaneous process, that is, the feed is at high temperature (110~200℃), high pressure (25~100kg/square centimeter) and High shear In the environment of shear force and high moisture (10%~20% or even 30%), through continuous mixing, tempering, heating, pressurization, curing, extrusion die hole and sudden decompression, large and large granules are formed. Porous pellet feed.( Feed Pellet Line)Second, the process is different:
1. Post-curing: the pellets from the granulator are heated and maintained, and the equipment to improve the degree of curing can greatly improve the
To improve the stability of pelleted feed in water, this process is called post-curing.
2. After the raw materials are treated with high temperature and high pressure, the feed starch gelatinizes and expands in volume. After the powder is quenched and tempered, it is extruded from the die hole under high temperature and high pressure, and the density is less than 1. The beverages come in various shapes and are suitable for aquatic animals, young animals, ornamental animals, etc. .
Extended Information:
After the feed material is extruded, the aroma is increased, the palatability is improved, and the appetite of animals can be stimulated. At the same time, the degree of conversion of long-chain structures of organic substances such as proteins and fats into short-chain structures is increased, thus making it easier to digest.Since the protein is bound to the starch matrix, it is not easily lost during feeding. The protein is only released when the digestive enzymes in the animal break down the starch, increasing the potency of the protein.
The expansion process also denatures the protein, inactivates many anti-nutritional factors, changes the tertiary structure of the protein, and shortens the hydrolysis time of the protein in the intestine. For ruminants, puffing produces rumen non-degradable protein, that is, rumen-passing protein, which can avoid animal ammonia poisoning and improve protein utilization.
