Aquatic feed extruder

Unique Technology and Design of the Zhengchang Aquatic Feed Extruder

The Zhengchang aquatic feed extruder is supplied to customers through Sama Gostar Kohan with advantages such as guaranteed quality, effective conditioning, durability and safety, a new high-quality generation, lower energy consumption and high feed quality.

Guaranteed Feed Quality with the Zhengchang Aquatic Feed Extruder

• A newly designed conditioner delivers better conditioning results than similar types. It improves uniform material mixing flow and mixing quality.

• A multi-screw (coaxial extruding) system in the aquatic feed extruder increases production capacity. Spare parts with high hardness and wear resistance give a smooth discharge flow and improve product uniformity.

• Knife speed can be adjusted to the user’s needs to control cutting quality.

• An automatic knife gap adjustment system guarantees product quality. It gives the feed a smooth, firm and uniform surface and solves appearance problems caused by cutting.

Effective Conditioning

• High adaptability for precise processing of diverse feed formulas.

• Die installation and replacement in the shortest possible time, avoiding production downtime.

• Less reliance on operator skill thanks to a computerised control system with a touch screen.

Durable and Safe

• Imported bearings, a high-precision gearbox, a circulating cooling and lubrication system, load control and overload protection ensure stable, steady operation of the aquatic feed extruder.

• Parts such as the screw and sleeve are made of alloy steel with high wear resistance and a long service life.

• Floating or sinking feed can be produced according to user needs. An auxiliary density control system can be used to produce high-density extruded feed.

New Generation of Aquatic Feed Extruder Technology

• The new conditioner design fully cooks the materials, increasing the degree of gelatinisation. It improves feed quality and production capacity while reducing energy consumption.

• An automatic control system and automated process control increase production efficiency.

• Automatic conditioner cleaning reduces material waste and therefore pollution.

• For example, when the 168F extruder with 160 kW of power and a 4 mm die is used to produce floating fish feed, output reaches 7.19 tons per hour, 30 to 50 percent more than other extruders. Main power consumption is 20 kW per ton.

A New Generation of Quality

• Multi-screw (coaxial continuous) technology ensures a uniform extrusion flow and smooth discharge.

• The angle of the cutting knives is designed to improve cutting, so the feed has a smooth, firm and uniform surface and appearance problems caused by cutting are solved.

Using the World’s Latest Technology in the Aquatic Feed Extruder

• The twin-screw structure of the aquatic feed extruder raises the oil content of the feed up to 22 percent.

• It increases oil absorption in the feed.

• The extruded feed production process is controlled with PLC touch-screen technology.

Lower Energy Consumption and High Feed Quality

• Die and gearbox life is extended beyond 5,000 working hours.

• Can produce sinking feed (such as shrimp feed) with about 30 percent starch.

• Can produce both floating and sinking feed with a single screw type.

• Sinking feed capacity increases by 10 to 20 percent.
