Extruders

Today, in the converting industries and new generation of technologies for the food and feed production, extruders have found a very special place. It plays an important role in the manufacture of pasta, ready-to-eat cereals, processed snacks and soybeans (TSP for human use), aquatic feed and pet food. The process involves a combination of several unit operations including mixing, cooking, kneading and shaping. The extrusion method for feed production has become very popular over the last two decades for a number of reasons:

Garma Electric generates and imports different types of extruders, depending on the application, kind of raw materials, capacity and customers budget.

In the aqua feed production process, it is essential to consider the feed characteristics for the specific species of fish and shell fish. ANDRITZ offers unique, high-capacity extrusion lines for the production of all kinds of feed for fish and shell fish. The ANDRITZ extruders ensure that the feed has the right physical properties – giving it the correct sinking attributes according to where in the water the feed should be accessed.
ANDRITZ single screw extruders represent state-of-the-art technology, ensuring high quality aqua feed at minimum operating costs.

Extruding feed is primarily a matter of cooking the starch. The better the starch is cooked, the better the quality of the feed. However, it is equally important to control the expansion of the feed, thus influencing density which determines both sinking and floating properties
