How to Choose the Right Dry fish feed pellet extruder machine for Your Needs？

Select equipment based on aquaculture scale: Match production capacity requirements. The scale of aquaculture directly determines the required equipment capacity. The daily feed demand must be calculated based on the pond area and the number of fish to select a model with corresponding capacity. For family fish farmers (5-20 mu of fishponds), with a daily feed requirement of 50-200 kg/day, a small dry-type fish feed pellet processing machine with a capacity of 50-150 kg/hour is recommended. For example, the SKJ-150 model, with a capacity of 150 kg/hour, has a purchase cost of approximately 80,000-100,000 RMB and can fully meet daily production needs. For small fish farms (20-50 mu of fishponds), with a daily feed requirement of 200-500 kg/day, a medium-sized machine with a capacity of 150-300 kg/hour is recommended. For example, the SKJ-300 model, with a capacity of 300 kg/hour, has a purchase cost of approximately 150,000-200,000 RMB. For small and medium-sized feed processing enterprises that need to supply surrounding fish farmers, a large machine with a capacity of 300-500 kg/hour is recommended. For example, the SKJ-500 model, with a capacity of 500 kg/hour, has a purchase cost of approximately 200,000-300,000 RMB and can meet the needs of mass production.

Select the appropriate machine based on the aquaculture species: Match the feed specifications. Different fish species have varying requirements for feed pellet size, hardness, and sinking properties, necessitating the selection of a machine model capable of producing the corresponding feed. For bottom-dwelling fish such as carp and grass carp, which require 3-5mm sinking pellets, a machine with a large-aperture die (3-5mm) and a screw length-to-diameter ratio of 18:1-22:1 is recommended to ensure compact pellets with good sinking properties. For fry or small fish (such as gudgeon), which require 1-2mm fine pellets, a machine with a small-aperture die (1-2mm) and a wide adjustable screw speed range (200-400 rpm) is recommended to produce fine, soft pellets suitable for fry. If raising multiple fish species simultaneously, a machine with a quick-change die and adjustable screw speed is recommended to enhance equipment versatility.

Selecting a machine based on raw material type: Matching the machine to the raw material adaptability. Dry-type floating fish feed pellet making machines have certain requirements for raw material adaptability; therefore, a suitable model should be selected based on the commonly used raw materials. If the commonly used raw materials are basic ingredients such as corn, soybean meal, and fishmeal, with simple composition and moderate moisture content, a standard single-screw dry extruder will suffice. If the raw materials contain a significant amount of bran, peanut meal, or other coarse fiber, a twin-screw dry extruder is recommended. The meshing rotation of the twin screws enhances the extrusion effect, ensuring thorough softening and extrusion of the coarse fiber. If the raw materials have a high protein content (over 30%), a model with a length-to-diameter ratio of 22:1 or higher is recommended to extend the residence time of the raw materials in the extrusion chamber, ensuring sufficient protein denaturation and improving feed digestibility.

Selection Considerations: Consider both cost and service. In addition to capacity and adaptability, the cost-effectiveness and after-sales service of the equipment should also be considered when selecting a model. Prioritize well-known and reputable manufacturers to ensure reliable equipment quality. Understand the manufacturer's after-sales service policies, including installation and commissioning, technical training, and spare parts supply, to avoid problems that cannot be resolved promptly during subsequent use. Simultaneously, consider your budget and choose a model with high cost-effectiveness to avoid blindly pursuing high capacity and wasting costs. For example, family fish farmers with limited budgets do not need to choose high-capacity models; a dry-type fish feed making machine can meet their needs and reduce investment pressure.
