Product Introduction

Dry type fish feed extruder is a commonly used machine for producing floating or sinking equipment is suitable foismall to medium-sized fish farms or mini feed processing plants,

‘slew!ue nenbe sauio pue’sqes ‘dw!цs ‘us!} so」 paa↓ joauiul pasn 从apIM SI pue

lt has a unique design that allows precise control over the density of the final feed, making it possible to produceeither floating or sinking feed as needed, At the same time, operators can aciust the process parameters to controlthe texture of the feed, such as its ability to absorb oil during later coating processes.

As a professional feed machinery manufacturer, RiCHl offers dry fish feed extruders mainly for producing aquatic feed pellets with diameters ranging from 0.5 to 8 mm in various shapes and lengths. They can also be used to produce pet or poultry feed pellets up to 50 mm in diameter.

How the Dry Type Fish Feed Extruder Works

RiCHl dry type fish feed extruder is mainly made up of a feeding device, screw,pressure chamber, shaping die, cutter, driving system, and control system.

Here’s how the dry single-screwfish feed extruder works.

First , the mixed raw materials are put into the machine through the feeding port. As the screwr otates,it pushes the materlals into the machine, The materlals are pressed:and rubbed between the screw and the barrel, which causes heat (no external heating is needed). Thisheat makes the starch gelatinize and the protein denature, turning the powder into a sticky mass.

When the pelets come out ofthe die,the pressure drops quickly. The moisture insideturms into steam and expands,making the pelets light and aigy.Depending on how much they expandthe pellets can either float on water or sink to the bottom. This meets the different feeding habits of various fish.

Duing the whole proces, the machine uses the mechanical enrgy from the screw rotationto create hea, sono extra steamis needed.Both the screw and barrel are made fromwearresistant,high temperature aloy stel The machine has a compact design and is easyto operate, making it an economical and practicalsoltion for fsh fed production.

Technical features

Single-screw dry fish feed extruder is simple in structure, ffordable, and very stable to use. This machine has been developed for manyyears with mature technology, making it reliable and problem-free. For over 40 years, it has been the main equipment for producingextruded fish feeds, especially suitable for low-protein feeds for adult fish like tilapia, grass carp, and carp.

In the production of ordinary feeds, such as those used formixed pond fish, this machine offers significant advantages.Raw materials do not need to be ground too finely; most canpass through a 30 to 50 mesh sieve, This eliminates the needfor expensive grinding equipment, saving costs and makingproduction faster and easier.

Nutrient Retention

The dry extrusion process does not requireadded water. The material stays in thehigh-temperature area for a short time, whichhelps reduce the loss of heat-sensitive vitam ins and proteins: This helps keep the nutrients inthe feed.

Suitable Animals

The feed made by dry extruders is usually hard and dense, with low watersolubility. it is commonly used in making fish feed. The machine can adjust thesize and shape of the feed, and control whether it floats or sinks. This helps meetthe eating habits of different aquatic animals like fish, shrimp, and crabs. it canalso be used to make feed for many land animals, The machine settings can bechanged based on what kind of animal feed you need.

A Complete Fish Feed Production Line

In aquaculture, high-quality feed is very important for fish to grow fast and stay healthy.If you plan to produce your own fish feed, just using a dry type extruder is not enough. Because the extruder’s main iob isonly to shape the feed into pellets, it cannot complete many important steps before that.

n fact, making fish feed is a systematic and complex process. The whole process includes several steps.aw material selection, grinding, mixing, pelleting, drying, cooling, and finally packaging.ach step is important and affects the quality of the feed and the health of the fish.Inly by doing each step well can you
broduce high-quality fish feed that is nutritionally balanced, easy to digest, and consistently good in quality.
