Professional extrusion processing of meals and feed products has become practiced for more as compared with 60 years. Spiral extruders were initial used as continuous cooking devices while in the late 1930s. The first commercial application on this extruded cooking process was in the mid-1940s.

The end product will be the puffed corn meal indulge. Today, extrusion cookers have become the main continuous cooking equipment from the commercial production of the majority of dry pet food and aquatic feed and also some applications of animals feed.

This pellet producing machine can produce aquafeed. Now, the aquafeed extrusion process may be known as a high-temperature, short-time bioreactor that can transform any number connected with raw materials into advanced beginner or finished products which may have high consumer appeal.

An important application of the extrusion process to animal feeds is the production of aquafeeds. Using this type of application, it not only increases the digestibility of nutrients which could improve the palatability of food and promotes the stability and stor-ability belonging to the formed feed particles.

Sometimes, it is desirable or necessary to produce a floating feed to support the feeding habits on the target species. In some other cases, extrusion provides a method of agglomerating a ton of ingredients into a sinking food that is water stable and is able to stay in the water column for a number of hours without disintegrating.

Entire, extrusion equipment used these days to process animal rss feeds generally falls into two categories: Single screw perch feed extruder and twin-screw sea food feed extruder.

Single prop extruder is simple, by using a rotating belt-way with continuous unadjustable spindle speed. It can get very good blending through high-speed operation very quickly. Solid conveying, melting, pumping, and mixing occur simultaneously and they are interdependent.

Nevertheless, it is usually inefficient and process handle is difficult. What’s more, the conveying capacity of a single extruder is poor under underhand, compared to the similar power twin-screw extruder, it has the production is lower.

This is because the transfer method is definitely pressure-sensitive, the pressure will produce reflux, thereby the actual transmission efficiency is lowered. However, the single screw perch feed extruder purchase cost is below twin screw extruder.

In order to create a design together with greater operating flexibility sufficient reason for greater operational control, full screw machines were formulated. Twin-screw extruders can become co-rotating, counter-rotating, intermeshing, or non-intermeshing in terms of basic designs.

The twist design of twin-screw extruders can dramatically affect operating efficiency and machine capability. Screw components while in the feed section of the barrel can be single, double, or sometimes triple flight arrangements.
