The selection and configuration of the loach feed pellet mixer should be comprehensively considered

The selection and configuration of the loach feed pellet mixer should be comprehensively considered based on factors such as the scale of aquaculture, characteristics of raw materials, production efficiency and cost. The following are the selection and configuration suggestions based on the search results:

I. Clarify Core Requirements

Farming Scale

Small-scale farming (household/small-scale farms): Choose small flat die pellet machines with a production capacity of 50-200kg per hour (such as 120/150 models) 124, suitable for 220V power supply, easy to operate and with low maintenance costs.

Large-scale farming (large-scale farms/processing plants): It is recommended to use ring die pellet machines with a production capacity of over 300kg per hour (such as 250/260 models) 36, which need to be matched with three-phase power (380V), supporting continuous production and high-intensity operations.

Raw material compatibility

Protein raw materials (such as fish meal and soybean meal): It is necessary to pre-treat them with an extruder to increase the digestibility by 79%. It is recommended to choose a twin-screw extruder (such as DH80-II type), which can handle high-protein and high-fat formulas well 7.

Fiber raw materials (such as straw and wheat bran): It is preferred to select a ring die pellet mill, as it has a better pressing effect on crude fiber 48.

II. Key Equipment Selection and Configuration

Pellet mill type

Flat die pellet mill: Suitable for small-scale and coarse feed processing. Recommended model: 150 type (output 120-150kg per hour), adjustable die hole diameter of 3-5mm, suitable for mud carp feed pellet requirements.

Ring die pellet mill: Suitable for large-scale production, such as HX-250 type (output 1-1.5 tons per hour), die hole diameter can be customized to 1.5-3mm, meeting the requirements of fine mud carp feed pellets.

Expander (optional)

Puffing can enhance the palatability and nutritional utilization rate of feed. The LQ-40 single-screw puffing machine is recommended, suitable for fish and shrimp feed, and supports the processing of floating pellets 9.

Auxiliary equipment

Blender: Ensure the raw materials are evenly mixed. A vertical blender with a capacity of 500-1000L is recommended (Model 37).

Crusher: Process the raw materials to a fineness of over 80 mesh to enhance granulation efficiency. A hammer mill crusher with a power of 7.5-15kW is recommended (Model 36).

Cooling/Drying Equipment: A multi-layer mesh belt dryer (such as a 5-layer oven) can quickly remove moisture and prevent feed from molding (Model 7).

III. Configuration Considerations

Selection of Die Hole Diameter

The recommended aperture for loach feed pellets is 1.5-3mm. The compression ratio (usually 1:6-1:8) should be adjusted according to the adhesive property of the formula.

Power and energy consumption

The small flat die pellet mill is suitable for 2.2 - 7.5kW motors, and the large ring die pellet mill requires 18.5 - 30kW power. If the power supply is unstable, diesel-powered models (such as the 200A type) can be selected. Maintenance and accessories.

Regularly clean the pressure rollers and molds to prevent clogging. 3. Prefer manufacturers that offer customized drilling processing services for easier mold replacement in the future. 16. Cost performance and brand.

Recommended Brands: Green Field (for household use), Jiusheng (for large ring die pellet machines), Luqiang (for extruders). The price range varies from 2,000 to 30,000 yuan. It is necessary to compare after-sales service and spare parts supply capabilities.

IV. Recommended Configuration Schemes

Scale of Breeding Device Combination Reference Model Estimated Cost

Family/Small-scale Breeding Flat die pellet machine + Crusher + Mixer 150-type pellet machine + 7.5kW crusher 5,000 - 8,000 yuan

Medium-scale Breeding Ring die pellet machine + Single-screw extruder + Cooling equipment HX-250 type + DH65-III extruder 20,000 - 50,000 yuan

Large-scale Processing Factory Ring die pellet machine group + Twin-screw extruder + Automation line 260-type ring die machine + DH95-II extrusion line 80,000 - 150,000 yuan

V. Extended Suggestions

Formula Optimization: Refer to the mud carp feed formula (such as 20% soybean cake + 26% fish meal + 35% corn flour), and ensure that the pellet machine supports the pressing of high-protein raw materials.

On-site Testing: It is recommended to request raw material trial machine services from the manufacturer to verify the equipment's adaptability.

Through the above configurations, production efficiency, feed quality, and cost control can be balanced, meeting the diverse needs of mud carp breeding.
