Feed Extruding Machine

Extruders are the machinery used to produce extruded petfood, (floating) extruded aquatic feeds and extruded animal feeds.

The extrusion cooking process, because it causes a high level of gelatinisation of starches, results in feeds with good water stability. It can produce ‘expanded’ floating feeds as well as sinking pellets. The process also improves the digestibility of the product. However, extrusion cookers are usually very large and expensive to purchase and operate.

Feeds which have ingredients such as soybean meal and cereal grains can be made more digestable, and the nutrients are therefore more available. Floating feeds are made using extruders along with highly water-stable sinking feeds which can be made with extruders as well. In some cases, extruders are used just to prepare feed materials, such as dry extrusion of soybeans.

Basically, an extruder is a long barrel with a screw auger inside which is specially designed to subject feed mixtures to high heat and steam pressure. When feed exits the die at the end of the barrel, trapped steam blows off rapidly, the soft warm pellets expand, and a low density floating pellet is produced. Extruders are very versatile, and can make feeds with many different characteristics. The main problem with extruders is that they are expensive to buy and maintain, and the feed manufacturers pass this cost on to feed buyers.

Today, the extrusion process is considered a high-temperature, short time “bioreactor” that can transform any number of raw materials into intermediate or finished products that have high consumer appeal. Food examples of items include an infinite variety of snacks, pasta, textured vegetable protein, breakfast cereals and the like. In terms of tonnage, there is little doubt that pet food reigns at the top. Extrusion allows the continuous cooking of the starch fraction of a formula necessary for the digestive requirements of companion animals and gives the processor the ability to create nearly any shape that might appeal to the pet owner.

This Feed Extruding Machine is mainly utilized for making floating fish feed pellets or sinking, slow sinking fish feed for catfish, aquarium fish, shrimp, tilapia, red or black porgy, rainbow trout, carp; it can also be pet food extruder for making pet food for dog and cat. You can also use it to make extruded feather meal.as a protein additive to replace fish meal.
