Extrusion Feed Processing Plant

Small to Medium Scale Feed Extrusion Line


Make Extrusion Feed for Aquatic animal and Pet

In the feed extrusion process, the feedstuff actually go through the condition of high temperature, high humidity and high pressure. When the feed pellets are discharged from the pellet die holes, the pressure is dropped from high pressure to about 100kPa, and the moisture in the feedstuff immediately transforms from liquid to gas and distributes out of the feed. As a result, the feed materials expand and form the so-called extrusion feed.

 

Dry-tye Extruder and Wet-type Extruder

Our extruder machines are designed with auto feeding system, auto temperature control system and electric heating device to improve production efficiency. Besides, it is eay to control the feed floating time by adjusting the puffing degree.

The dry type extruder refers to the ones without conditioner, just as shown in the above picture.

The wet type feed extruder is designed with a conditioner. Compared with the dry type ones, wet type extrusion machines have higher production capacity. This is also wet type extruders are suggested in most large scale production line.

Aquatic Feed Processing Plant

The processing of aquatic feed is far more demanding than that of livestock and poultry feed processing, since aquatic animals such as fish and shrimps have small gastrointestinal tracts and poor digestion and absorption. This also why it is particularly important to select the right equipment for setting up aquatic feed processing plant.

 

4 Things You Should Know Before Starting Your Feed Mill

To choose the right aquafeed processing equipment, you must understand the characteristics of aquafeed firstly.

• Small particle size: Due to the short digestive tract of aquatic animals and related physiological characteristics, in order to speed up digestion and absorption, aquafeeds should have a smaller particle size than livestock and poultry feeds, such as salmon and prawns, the feed size should be 80 ~120 mesh.
• High protein content and low carbohydrate content: The protein content of livestock and poultry feed is generally less than 20%, while the protein content of aquatic animal feed is mostly 30-40%, and the protein content of turtle and catfish feed is as high as 65-70%.
• High adhesion and water resistance: For some kind of fish feed, shrimp feed, the stability in water should be maintained for more than 2 hours.
• Aquaculture feed production is strictly prohibited for cross-contamination. Some raw materials need to be aseptic processed. When selecting extrusion feed processing equipment, make sure it has little residue and is easy to clean, especially when when producing shrimp and squid feed which is not allowed to simultaneously produce other kinds of feed to prevent cross-contamination.

To start fish feed processing business and produce high quality aquafeeds, choose a reliable and stable feed processing machinery should be the very first step. Besides, you must rely on feed nutrition scientific, reasonable processing techniques and combine them with advanced. ABC Machinery is an experienced manufacturer and supplier of feed machine and feed plant. We offer more than equipment, but also technical support and guidance.

Extrusion Feed Vs Compressed Feed

Extrusion feed is made by feed extruder, while compressed feed is made by feed pellet press.

• Common Points: Both the extrusion feed and compressed feed have the advantages of good palatability, avoid picky eaters, easy to transport, help digestion, reduce waste in the feeding process, etc. But extrusion feed also has some unique advantages listed below.
• Extrusion Feed Superiority: Starch gelatinization in the feed is high, the protein is more easily digested, and the utilization rate of the animal feed is improved. What’s more, expanded feed has excellent floating property, and it is more convenient for the observation of the feeding condition. Besides, the water pollution can be controlled to the maximum extent. These are also the main reasons for the widespread use of extruded feeds.
