What's the Expanded Feed for double screw fish feed extruder?

Expanded/Puffing Feed Introduction:

The expanded feed is a kind of puffy and porous feed formed by expanding the feed. Double screw fish feed extruder extruding is a processing technology that depressurizes the material after high temperature and high pressure treatment and changes some physical and chemical properties of the material by the instantaneous evaporation of water or the expansion characteristics of the material itself. It is divided into air flow extruding and extrusion extruding. After the feed was expanded, the starch gelatinized, the long chain structure of protein, fat and other organic compounds became short chain structure, the fiber structure and cell wall were destroyed, and the harmful and inhibitory factors such as myxoderma in rapeseed meal, gossypium in cottonseed meal, and anti-trypsin in soybean meal were destroyed, making it easier to digest. At the same time, it overcomes the disadvantages of the traditional powder compound feed and pellet feed, such as poor water stability, fast settling speed and easy to cause feed loss and waste. The puffing effect is affected by the ratio of raw materials, starch content, moisture content, and puffing temperature and other factors. Combined with the puffing characteristics, the starch raw materials in the raw material formula should be ensured to be above 20%, and the additives should be resistant to high temperature, or the amount should be increased.

Expanded Feed produced by double screw fish feed extruder advantages:

The expanded aquatic feed can float on the water surface for a long time, which is easy to feed and manage and is beneficial to labor saving. Generally, the powder produced by the expanded feed is less than 1%, and the floating time of the high quality floating fish feed can reach 2 hours. Under normal circumstances, compared with powder or other pellet feed, it can save 5 ~ 10% feed, and it is easy to observe and control the bait casting, and reduce the pollution of powder and residual bait to the water.

Application of Expanded Feed produced by double screw fish feed extruder

In terms of farming methods, floating fish feed can be used in pond fish farming, paddy field fish farming, flowing water fish farming, cage fish farming, factory fish farming and large surface intensive farming, which has a wide range of applicability. From breeding, besides domestication extremely hard to a small number of benthic fishes, feeding the water can be a good feeding buoyancy fish feed, such as bass, snakehead, view their MeiWa, fish, turtle, turtle, fork tail ð « š ” and other varieties of products and conventional breeding of grass carp, carp, crucian carp, etc For the species of frog and perch with special physiological function, it is more convenient to breed with floating feed and can show its superiority. Farmers with insufficient breeding experience and extensive management should choose floating feed. Some carnivorous fish like dark and afraid of light, in the use of floating puffing feed, but also need to train or feed at night. For the few benthic fishes which are very difficult to domesticate to the surface, it is better not to use the floating expanded feed, but can choose the sedimentation or slow sedimentation expanded feed.
