कंपनी की खबर What Are the Advantages of single screw fish feed making machines?

Low equipment procurement cost: Significantly lowering the entry barrier. The core advantage of the single screw fish feed extruder machine lies in its "simplified structure." Using a single screw as the core transmission component, it eliminates the need for the complex synchronous meshing transmission system, forced feeding device, and multi-stage precise temperature control system of a twin-screw extruder. Supporting equipment only requires basic components such as a feed hopper and cutting device. The procurement cost of a single unit is only 50,000-200,000 RMB (small to medium capacity models). Compared to the procurement cost of 200,000-500,000 RMB for a twin-screw extruder of the same capacity, the entry barrier for a single screw extruder is reduced by 60%-70%. For example, a single-screw extruder with an hourly output of 150 kg costs approximately 80,000-100,000 RMB and can directly achieve integrated extrusion production from raw materials to finished products; while a twin-screw extruder of the same capacity requires an additional steam system and precise temperature control device, with a total procurement cost exceeding 300,000 RMB, far exceeding the budget of small and medium-sized users.

Controllable operating energy costs: Simplifying energy consumption structure. The energy consumption of a single-screw floating fish feed machine is concentrated solely in the drive motor, eliminating the need for the energy consumption of auxiliary equipment such as steam heating and forced feeding found in twin-screw fish feed extruders. It relies on the frictional heat generated by the screw rotation to puff the raw materials, requiring no external steam heating. The drive motor power is typically 15-55kW. Based on an industrial electricity price of 1 yuan/kWh, the energy cost per ton of feed produced is only 150-200 yuan. In contrast, the comprehensive energy cost of a twin-screw extruder per ton of feed produced reaches 300-400 yuan, plus additional costs for steam fuel and water. For small-scale production scenarios with a daily output below 500kg, a single-screw extruder can save 30,000-50,000 yuan in energy costs annually, with a particularly significant long-term cost advantage.

Maintenance costs are low: parts wear out slowly and are easy to replace. The core components of a single-screw floating fish feed extruder machine (screw, extrusion chamber, die) have a simple structure and a relatively stable working environment, resulting in slower wear compared to twin-screw extruders (which endure high-intensity wear from meshing shear). The screw's lifespan is 1500-2000 hours, and the extrusion chamber's wear-resistant bushing only needs replacement every 1000 hours. The replacement process is simple, requiring no specialized technical team; users can operate it themselves. Annual maintenance costs are only 5%-8% of the equipment purchase cost. For example, a single-screw extruder with a capacity of 150kg per hour has an annual maintenance cost of approximately 4000-8000 yuan. In contrast, the annual maintenance cost of a twin-screw extruder reaches 10%-15% of the equipment purchase cost, and the core components need to be replaced simultaneously, making the maintenance cost 3-5 times that of a single-screw extruder.
