Seven Hills Innovation

A Fish Feed Making Plant is a complete production system designed to convert raw agricultural materials into high-quality floating or sinking fish feed pellets. The plant combines multiple machines to carry out grinding, mixing, extrusion, drying, cooling, and packaging processes — all customized to meet the nutritional needs of different aquatic species.

⚙️ Key Components of a Fish Feed Plant:

A Micro Fish Feed Extruder is a compact and economical machine designed to produce floating or sinking micro-size fish feed pellets for fry and juvenile fish. This machine is ideal for small-scale production, testing new formulations, or feeding delicate species that require micro pellets ranging from 0.5 mm to 2 mm.

⚙️ Key Features: 1. Compact Design

• Lightweight, space-saving, and portable

• Ideal for small farms, labs, and hatcheries

2. Pellet Size Options

• Produces 0.5 mm to 2 mm micro pellets

• Suitable for fry, fingerlings, ornamental fish, shrimp larvae

3. Feed Types Supported

• Floating pellets (for surface feeders)

• Sinking pellets (optional with die adjustment)

4. Production Capacity

• 20 kg/hr to 100 kg/hr

• Perfect for batch-wise or continuous feeding needs

5. Drive Options

• Available in single-phase (1–3 HP) or three-phase models

• Electric motor or gear motor driven

6. Temperature & Pressure Control

• Thermostat-controlled heating system

• Maintains optimum cooking for nutrient preservation

7. Pellet Cutter

• Adjustable knife for desired pellet length

• Smooth, uniform pellet shape

🧪 Supported Ingredients:

• Maize, rice bran, wheat flour, soybean meal

• Fish meal, vitamins, minerals, oil, binder (gelatin/starch)

✅ Advantages:

• Low investment, ideal for startups or research use

• Produces high-quality micro feed at low operating cost

• Customizable pellet size and shape

• Improves fish survival rate in early stages

• Easy to operate, clean, and maintain

📦 Applications:

• Ornamental fish breeding units

• Hatcheries (Tilapia, Rohu, Catla, Pangasius)

• Aquaculture research institutes

• Small-scale fish farms and feed startups

A 100 Kg/Hr Fish Feed Extruder is a compact and efficient machine designed to produce floating or sinking fish feed pellets from a variety of raw materials. It’s ideal for small commercial fish farms, rural entrepreneurs, and feed producers who want to make nutrient-rich, cost-effective fish feed onsite.

⚙️ Key Features: 1. Output Capacity

• Production rate: 80 to 100 Kg/hr

• Suitable for small-scale hatcheries and fish farms

2. Feed Type

• Can produce both:

  • Floating feed (for surface feeders like Tilapia, Rohu, Catla)

  • Sinking feed (for bottom feeders like Pangasius, shrimp – with die change)

3. Pellet Size Options

• Adjustable die molds for 0.5 mm to 8 mm pellets

• Suitable for fry, fingerlings, grow-out, and adult fish stages

4. Raw Materials

• Works with ingredients like:

  • Maize, rice bran, soya DOC, groundnut cake, fish meal, wheat flour, binder, minerals, oil, etc.

5. Construction & Material

• Heavy-duty mild steel or stainless steel body (optional food-grade)

• Alloy steel screw and barrel for longer life and wear resistance

6. Operation Mode

• Available in:

  • Single-phase (2–5 HP) for rural or small farm use

  • Three-phase (5–7.5 HP) for continuous production

7. Extrusion Technology

• Dry type extruder – no need for boiler or steam generator

• High temperature and pressure cooking for better digestibility and floatability

• Equipped with temperature control, heating coil, and cutter unit

8. Output Features

• Moisture content of final pellets: 7–10%

• Pellet float time: 8–12 hours (floating type)

• Durable, non-powdery pellets

✅ Benefits:

• Reduces cost of commercial feed by 30–40%

• Improves FCR (Feed Conversion Ratio)

• Customizable feed formulas for different fish species

• Easy to operate and maintain

• Compact design – fits in small sheds or farm buildings

The PCK 50 Kg/hr fish feed extruder is a locally manufactured, cost-effective machine designed for small fish farms, cooperatives, and training institutes. It is suitable for producing floating, sinking, and slow-sinking pellets for a wide variety of freshwater and ornamental fish.

✅ Key Features

A Fish Feed Extruder is a specialized machine used to produce floating or sinking fish feed pellets by forcing a mixture of powdered raw materials through a die under controlled temperature, pressure, and moisture. It is ideal for making high-protein, digestible, and water-stable feed for fish, shrimp, and other aquatic species.

⚙️ Types of Fish Feed Extruders: 1. Dry Type Extruder

• Does not require a boiler or steam generator

• Best suited for floating feed production

• Lower cost and easier to maintain

• Ideal for small to medium farms

2. Wet Type Extruder

• Uses steam pre-conditioning for higher gelatinization

• Produces higher-quality and durable feed

• Suitable for large commercial operations

• Requires a steam boiler and higher investment
