Fish Feed Extrusion Process with Extruder Machine

图片
Fish Feed Extrusion Process Origin The early-stage extrusion processing was mainly used in food processing industry. Since the nineteen fifties, America had started to use this technology for feed processing field, especially for processing pet food and pretreatment of feed ingredients. Till the nineteen eighties, it has become the fastest developing technique of feed processing industry in the world, and has started to be applied in each sphere of feeding stuff industry, widely used for dry pet foods, some applications for livestock feed and fish feed. With the unceasing development of technology and the continuous rising of people living standard, the growth of aquaculture must follow the principle of producing green food without pollution, bringing significant attention and lots of intensive study on  aqua feed production technology . And there is a consensus that adopting  extrusion process to make fish feed   is the major means to ensure producing high quality and...

Processing and Application of Floating and Sinking Fish Feed

图片
With the further development of fish farming industry, extruded fish feeds have obtained more and more wide applications in virtue of unique advantages including high nutrient, good palatability, strong digestibility and so on. As a new technology to produce feed, extrusion processing means that in the environment of high temperature(110-200°C), high pressure(25-100kg/cm2) and high water content(10%-20%, even 30%), fish feed stuffs mixture, through heating tempering, deep mixing and particles formation, would puff and afterwards shape into extruded feed when out of fish feed extruder machine . On the basis of density variation and puffing degree, extruded fish feed can be segmented into floating fish feed and sinking fish feed. Currently, the floating feed is the most widely used extruded feed in fish farming, and it has relatively mature technology. That is, floating extruded feed pellets are both produced through modulator for heating and modulation, via continuous mixing proce...

How to Lower the Water Quality Pollution from Fish Feed

图片
Currently, the intensive aquaculture industry has two obvious characteristics: high-density releasing fingerlings and feeding fish with a large quantity of artificial formula feed. As is well known, artificial compound aqua feed is the primary nutritional source of intensive aquaculture, however, the heavy use of manufactured fish feed is also one of main reasons that cause the pollution of aquatic water. In order to figure out the pollution problem of feed, people must control the source of pollution from a nutritional point of view, aiming at achieving the goal of green aquaculture.
