The DGP Series Diesel Dry-Type Fish Feed Extruder machine is a hybrid-drive solution specifically engineered for regions with unstable electrical grids or off-grid farm locations. By utilizing a high-torque diesel engine as the primary power source for the extrusion screw, and a secondary electrical system for precision control, this machine ensures that high-quality floating fish feed production remains consistent regardless of local power infrastructure.

Based on the DGP series engineering design (refer to the diagram), the machine integrates mechanical power with electronic precision:

• Diesel Engine (Main Drive): Provides the massive torque required for the friction-heating and extrusion process.
• Puffing Heating Chamber: The core assembly where raw materials undergo high-pressure cooking and starch gelatinization.
• Hybrid Control System:
• Control Panel: Manages the independent electrical components.
• Feeder & Knife Motors: Unlike fully manual machines, these are powered by electricity to allow for variable speed control, ensuring uniform material intake and precise pellet length.
• Dual-Option Outlet: Equipped with interchangeable die molds to produce pellets ranging from 1mm to 9mm.

Data verified against the latest DGP Diesel dry type floating fish food pellet extruder machines configuration:

A. High Torque for Local Raw Materials

In markets like India, feed often contains high percentages of De-oiled Rice Bran (DORB) or fibrous oil cakes. Diesel engines provide a more stable torque curve compared to low-voltage electric motors, preventing "stall-outs" during high-density extrusion.

B. Precision Cutting via Independent Motors

While the main screw is diesel-driven, the independent electric cutter motor (controlled via the panel) allows the operator to adjust the "cutting frequency." This is critical for producing 1mm-2mm starter feed for fingerlings, where length uniformity is vital for ingestion.

C. Pathogen Neutralization

The dry-type extrusion process reaches internal temperatures of 100°C–150°C. This thermal energy is sufficient to eliminate Salmonella and other waterborne pathogens, ensuring the bio-safety of the feed produced on-site.

To maintain the machine's efficiency in tropical or high-dust environments:

• Diesel Engine Care: Change engine oil and check air filters every 100-150 hours of operation to prevent overheating.
• Screw & Sleeve Inspection: The alloy screw is the primary wear part. Monitor the pellet "expansion ratio"-if pellets become dense and fail to float, it may indicate a worn screw requiring replacement (typically after 50-100 tons of production).
• Bearing Lubrication: High-speed rotation generates significant heat; use high-temperature resistant grease for the main shaft bearings.

Q1: Since it's diesel-powered, do I still need electricity?
A: Yes, a small amount of electricity (single-phase or a small generator/battery) is required to run the Control Panel, Feeder Motor, and Cutter Motor. This hybrid setup ensures the main power is independent of the grid while maintaining precision sizing.

Q2: How does the Diesel Dry Type Fish Feed pellet maker machine control temperature without a boiler?
A: It uses "Dry-Type" technology. Heat is generated through mechanical friction between the screw and the material, supplemented by electrical heating rings in the puffing chamber. The diesel engine provides the mechanical energy to drive this friction.

Q3: Can this Diesel Dry Type fish feed pellet extruder machine produce sinking feed for shrimp?
A: Yes. By adjusting the formula (reducing starch/yeast) and decreasing the heating temperature via the control panel, the machine can produce high-density sinking pellets suitable for bottom-feeders.

Q4: Is the Diesel Dry Type fish feed making machine difficult to start in cold or humid weather?
A: Most models from DGP-60 upwards come with an electric start system (battery-powered), making it as easy to operate as a standard electric motor, even in humid coastal aquaculture zones.
