What is the difference between floating and sinking aquatic feed solutions?

In order to meet the high requirements of the world market for cost-effective and high-performance fish feed pellets, we specially customize the floating type fish feed production line. It is used to press various materials into high-grade floating aquatic feed pellets.

Its production capacity ranges from 0.2 to 10 T/H and above. The main raw materials include fish meal, starch, bone meal, soybean meal, and peanut meal. It is suitable for the production of fish feed for tilapia, eel, catfish, and other species.

Our sinking type fish feed production line is specially designed for manufacturing sinking aquatic feed pellets. Common ingredients include fish meal, starch, bone meal, soybean meal, and peanut meal. It meets the feed requirements for shrimp, salmon, trout, cod, and moai.

What is the difference between pelleted and extruded feed?

When making granular aquatic feed (sinking feed pellets), firstly, crush different raw materials with a crusher, and then mix them with a feed mixer machine. The mixed raw materials are semi-finished products of fish or shrimp formula feed. Next is the process of making pellets. The premixed formula feed enters the fish feed pellet making machine, and then the pressing roller and the ring die press out the granules (granules). The diameter dimension of the ring die is the diameter of the feed pellets. The ring dies with different diameters are used when making different sizes of pellet feeds.

When making extruded pellet feed (floating feed pellets), firstly, raw materials are crushed. If the raw material for floating fish feed is powder, it does not need to be crushed. Then mix the powder evenly. After that, the aquatic feed raw materials are uniformly fed into the floating fish feed extrude machine. Under great extrusion pressure and high temperature, the extruded feed pellets will expand when coming out of the floating fish feed extruder machine and become pellets, which can float on the water’s surface.

What are the advantages of pellet feed?

As far as production is concerned, pellet feed has a series of advantages, such as low investment cost, high output, low unit production cost, fast return on capital, etc. In addition, compared with the natural food and unprocessed grain feed, pelletized feed is easier to store, package and transport. For fish farmers, the price of pellet feed is low but the feed coefficient is high, which not only makes the main cultured fish (such as grass carp, crucian carp, and carp) grow well but also makes the mixed cultured fish (such as silver carp and perch) grow well.

How to select the right pelletizing equipment?

A fish feed making machine is a feed processing machine that takes corn, soybean meal, straw, grass, and rice husk as raw materials and directly presses them into pellets after crushing raw materials. It is better suited for the production of conventional sinking aquafeeds.

The twin screw floating fish feed extruder machine has the advantages of strong adaptability, sliding transportation, and self-cleaning. Therefore, a twin-screw floating fish feed extruder machine is generally used in the production of aquatic products and pet feed with high-added value, such as eel, sea fish, juvenile fish feed, and other high-added value aquatic products and pet feed pellets.

How to produce clean aquaculture feed pellets?

We can incorporate a raw material screening step before the crushing section. Raw materials that do not need to be crushed are input from the auxiliary feeding port, and sundries and bulk materials are removed through the fence and then transported to the main cleaning screen through the conveyor and elevator to remove ropes and large debris. The raw materials enter the magnetic separator to remove the metal debris and then enter the batching warehouse to wait for batching.

The dust generated by the feeding enters the bag-type dust removal system for negative-pressure dust removal. The raw materials to be crushed pass through the fence to remove impurities. The hoist is sent to the main cleaning screen to remove impurities such as ropes and labels. Then the iron impurities are removed by the permanent magnet cylinder and then enter the warehouse for crushing.
