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...

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.

For more production of fish, some extra feed is needed in accordance with natural feeds in water. This extra served feed is called supplementary fish feed. Introduction of some supplementary fish feed are described below. Rice Bran: Rice dust is like powder. It is very common and cheap. It is a better fish feed. Rice dust contain about 10-14% of protein. Rice dust also contain vitamin B1, B2, B6 and small quantity of enzyme. Mustard Cake: Mustard cake can be found in small sized pieces. It is slightly yellow colored. Mustard cake has to served to fish by mixing with other food. Fat may gather in the liver of fish for long time consuming of cake. As a result the fish may die. 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: Wheat chaff contain fiber. It controls many types of fish diseases. Amount of fat in wheat chaff is low. So, it is better than rice dust as fe...

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...

Nutritionally complete, dry extruded feed (although extruded feeds are more expensive than compressed feeds of the same formulation, their advantages allow them to be significantly more economically efficient) should satisfy the nutrient requirements for the different life stages of tilapia, so feed manufacturers should pay much more attention to raw materials you are using, machines for making fish feed and feed production technology. The proper extrusion of the raw material and the balanced formulation of nutrients improve the tilapia production till harvesting. High growth rate and low feed conversions improve the economical/financial results of the fish farmers. ★ Protein source:  soybean meal; corn gluten meal (60% crude protein); soybean meal; fish meal (good quality fish meals contain crude protein levels above 66%, being an excellent source of highly digestible protein); fish hydrosylate; oil cake (it contains relatively high protein percentages-≥20%- and always consi...

Fish feed dryer is usually used in combination with fish feed cooler in the fish feed pellet line. Fish feed pellets are transported from fish feed extruder to the pellet dryer machine, then being conveyed on the mesh belt which is made of stainless steel.  Characteristics of Mesh-belt Type Fish Feed Dryer 1. High-efficiency and energy saving 2. Easy to install and maintain 3. Fast drying speed, high evaporation intensity 4. Convenient drying parameters adjustment, flexible operation, wide adaptation 5. Higher work capacity, the range of drying time is adjustable 6. Standardized production, users can increase the number of segments according to production Parameter of Fish Feed Dryer Model: FY-500 Mesh belt width: 500mm Total power: 10kw Capacity: 300-400kg/h
