Application Cases & Benefit Analysis of Twin-Screw Fish Feed Extruder Machine

 

Case Study 1: Production of Floating Feed for Sea Bass – Precise Adjustment of High Expansion Degree. A large-scale sea bass farm used a 500kg/hour Twin Screw Pet Feed Extruder machine to produce floating feed for sea bass, requiring an expansion degree of 85%-90% and a buoyancy rate of ≥98%. By precisely adjusting parameters: screw speed 380r/min, steam addition 2%, raw material moisture 12%, and using a 2.5mm die head, combined with a PLC intelligent control system that automatically adjusts the temperature (155℃ in the expansion section), precise control of the expansion degree was achieved (stabilized at 88%). Application Results: Sea bass feed intake increased from 75% to 98%, and feed waste rate decreased from 20% to 5%; due to improved feed digestibility (starch gelatinization degree 85%), sea bass growth rate increased by 18%, and the farming cycle was shortened by 20 days; the farming profit per acre increased by more than 3000 yuan. Simultaneously, in batch production, the expansion degree fluctuation was ≤±2%, feed quality consistency was strong, and sea bass growth uniformity improved by 25%.

Case Study 2: Grass Carp Sinking Feed Production – Precise Adjustment of Low Expansion Degree. A grass carp farming cooperative uses a 200kg/hour twin screw fish feed making machine to produce sinking grass carp feed, requiring an expansion degree of 35%-40% and water resistance ≥10 hours. Adjustment Strategy: Screw speed 280r/min, steam addition 1%, raw material moisture 13%, using a 4mm die head, and adjusting the steam addition in real time via an online moisture monitoring device. Application Results: The expansion degree is stable at 38%, the pellets are compact, sink quickly, and the water resistance reaches 12 hours; grass carp feeding activity is high, feed digestibility and absorption rate increases by 12%, fecal emissions decrease by 15%, and water pollution in the aquaculture water body is reduced; feed costs decrease from 3800 yuan/ton to 3500 yuan/ton (due to precise expansion degree, unnecessary raw material consumption is reduced), and the cost per mu (unit of land area) of aquaculture is reduced by 800 yuan.

 

Case Study 3: Multi-variety Feed Production – Full-Range Expansion Degree Adjustment A comprehensive aquatic feed mill uses a Twin Screw Fish Feed Extruder machine to simultaneously produce starter feed for fish fry (55% extrusion), semi-floating feed for carp (65% extrusion), and floating feed for tilapia (90% extrusion). By upgrading the PLC intelligent control system and pre-setting parameters for different feed formulations, coupled with an adjustable die head and online extrusion monitoring device, precise adjustment of the extrusion degree across the entire range was achieved. Application results: When switching between different feed production, parameter adjustment time was reduced from 30 minutes to 5 minutes, increasing production efficiency by 60%; the extrusion degree error for each feed variety was ≤±3%, ensuring stable quality, and the product qualification rate increased from 85% to 98%; due to adaptability to the needs of different fish species, product market competitiveness was enhanced, and sales increased by more than 40%. Simultaneously, precise adjustment reduced energy and raw material waste, lowering the unit feed production cost by 15%, resulting in annual cost savings of over 500,000 yuan.
