Food preparation through extrusion is a multi-functional thermo-mechanical method that has exploded in popularity in the food processing industry in recent years. It’s one of the most tried-and-true strategies that has stood the test of time. The extrusion process has become more refined and sophisticated as technology has progressed.
Extrusion, a commonly used feed, and food processing technology, involves pushing food items through small slots using a series of screws (or a single screw), which are then baked at high pressure and temperature before being enclosed inside a barrel.
The food extrusion industry was valued at $60.4 billion in 2019, before the pandemic, and is expected to rise to 81 billion dollars by 2027. It’s time to invest in a food extruder machine if you want to boost your food manufacturing company’s productivity and efficiency.
Food processing has come a long way in the last several decades. Food plants are now designed to improve their ability to mass-produce food, transport it over large distances, and make it considerably safer.
The food extrusion process is incredibly beneficial for the production of a wide variety of foods that we consume daily. It’s a sustainable and versatile technology that combines several unit operations into a single integrated process, including cooking, heating, forming, and shaping. It forces all melted ingredients through a ‘die’ opening or perforated plate which is typically designed specifically for the food being shaped.
Food extrusion entails a bioreactor system that pushes several mixed ingredients through a narrow, shaped opening, known as a die (Lisch and Launay 1893) to form various products, referred to as extrudates (Berek, 2009).
