Which has a faster return on investment: a single-screw or a twin-screw extruder machine for floating fish feed?

The forced feeding and efficient mixing provided by the twin-screw structure are key to increased production capacity. Unlike single-screw extruders that rely on gravity feeding, the Twin-Screw Fish Feed Pellet Extruder uses two screws rotating in opposite or the same direction to create forced conveying force. This prevents bridging and clogging of the raw material within the barrel, increasing the feeding speed by over 40%. Simultaneously, the shearing and mixing action of the two screws significantly improves the plasticization efficiency of the raw material within the barrel, raising the starch gelatinization rate from 75% with a single screw to over 90%, eliminating the need for secondary processing and directly increasing output per unit time. For example, a twin-screw extruder with a capacity of 3 tons per hour can achieve a daily output of 48 tons when operating for 16 hours, which is 2-3 times that of a single-screw extruder of the same power.

 

Stable output stems from the balanced structure of the equipment. The two screws of the Twin-Screw Fish Feed Pellet Extruder mesh with each other during operation, canceling out the radial forces generated. The vibration amplitude of the equipment is controlled within 0.5mm, only one-third that of a single-screw fish feed pellet extruder. This low-vibration characteristic not only reduces equipment wear, extending the service life of vulnerable parts (such as screws and dies) from 800 hours to 1500 hours, but also ensures the uniformity of feed pellet size. Test data shows that fish feed produced by twin-screw extruders has a pellet diameter deviation of ≤0.2mm and a pass rate of 98%, while the pass rate of single-screw extruders is only about 85%.

 

For large-scale production enterprises, stable production capacity can also reduce production costs. The unit energy consumption of the twin-screw fish pellet making machine is 15%-20% lower than that of a single-screw extruder, reducing the electricity consumption per ton of feed production from 120kWh to 90-100kWh. At the same time, continuous operation reduces the number of equipment start-ups and shutdowns, saving preheating time and reducing energy consumption during motor startup, further improving production efficiency.

 

 

 

 

MIKIM's fish feed pellet production lines and supporting machinery offer excellent value for money. Not only are they affordable, eliminating middlemen markups and allowing small and medium-sized enterprises (SMEs) and fish farmers to purchase complete sets of equipment at reasonable costs, but they also boast exceptional efficiency. The fully automated process, from raw material crushing and precise ingredient mixing to extrusion pelleting and maturation, is completed in one continuous flow. This results in high starch gelatinization rates and uniform pellet formation, significantly improving production efficiency and feed quality, truly achieving "low cost, high output." Choosing a MIKIM fish feed pellet production line means enjoying comprehensive pre-sales and after-sales service, including 24-hour online customer support, a one-year warranty on the entire machine, professional on-site installation, commissioning, and maintenance, and a stable supply of spare parts. Customers can buy with confidence and use with peace of mind, with both excellent value and service quality!
