Do you know how to choose the right aquafeed extruder?

15/01/2021

For a new aquaculture feed processing plant or an original feed production line transformed from an old plant, when using the extruder, the type and specifications should be considered first, and the supporting equipment should be determined according to the production capacity. Especially when the old factory is rebuilt, it is necessary to consider whether the production capacity of the original feed factory, dryer and cooler can support the normal operation of the new machine.

Features:

Puffing effect

For the processing of aquatic feed, the good expansion effect directly affects the formation rate of pellets, and the excellent and good rate can reach more than 99%. It is generally believed that the requirements for qualified extruded feed are: particle crushing rate less than 1%, particle floating rate (sinking rate) not exceeding 100%, uniform particle size, uniform color, and good water resistance; feed floating in water can be kept for 10 hours. The sunken type can stay in the water for 3 hours without collapse.

cost of investment

The investment price of a twin-screw extruder is 1.5 to 1.7 times that of a single-screw extrusion equipment with the same production capacity; the wearing parts and power consumption are about 1.5 times of the latter.

life

Different manufacturers' equipment has different service life due to the use of different structural characteristics and materials. Therefore, when selecting equipment, special attention should be paid to whether the structural design is reasonable. The key is the wear resistance of wearing parts and whether it can really reduce the wear of screws. In addition, it is necessary to consider whether it can achieve real energy saving. Those raw materials that have not been superfinely pulverized have more serious wear on the parts of the twin-screw extruder.

Shandong Arrow Intelligent Equipment Co., Ltd. is one of China's relatively large-scale puffed food machinery processing equipment and a comprehensive problem solver for the whole plant engineering with puffing machinery as the main body. The aquatic material produced by the company's twin-screw extruder has high protein , Complete nutrients, fast water absorption, timely softening, less dissolution loss, and no collapse. Modification and gelatinization is good for absorption, improving feed utilization rate and saving materials. Good absorption also reduces the nutrition of water and is more conducive to aquatic health. It can be applied to a variety of fish and shrimp aquatic products and is the best choice for aquatic feed manufacturers.
