Dry pasta manufacturing line from 1930s. The first extruder was designed to manufacture sausages in the 1870s. [4] Dry pasta has been produced by extrusion since the 1930s, [2] and the method has been applied to tater tots (first extruded potato product: Ore-Ida in 1953). [4]
Rubber extrusion is a method used to make rubber items. In this process, either synthetic or natural rubber that hasn't been hardened yet is put through a machine called an extruder. This machine has a desired shaped mold and a pressurized conveyor system.
Extrusion is the process of kneading and shaping at the same time and in the matter of a few minutes. This process takes place in an extruder which is a grooved extrusion cylinder equipped with an extrusion worm which is a shaft with deep thread around its core.
The liquid used in wet methods can be added directly to the product or via a humid environment. Using a fluidized bed dryer and multiple step spray drying are two examples of wet methods while roller compacting and extrusion are two examples of dry methods. Advantages of agglomeration for food include:
Extrusion based food printers can be purchased for household use, are typically compact in size, and have a low maintenance cost. Comparatively, extrusion based printing provides the user with more material choices. However, these food materials are usually soft, and as a result, makes printing complex food structures difficult.

Drying methods to make starches cold-water-soluble are extrusion, drum drying, spray drying or dextrinization. Other starch derivatives, the starch sugars, like glucose, high fructose syrup, glucose syrups, maltodextrins, starch degraded with amylase enzyme are mainly sold as liquid syrup to make a sweetener.
