Abstract:
The aim of this study was to develop a novel portable cold extruder, powered by a DC
power source, aimed at addressing the limitations of existing extrusion machines. The primary
objective was to design a low-cost, innovative solution that simplifies the extrusion process
and enhances productivity for medium-scale industries and households.
The portable cold extruder features a movable cylinder that allows for convenient
preparation of a variety of cold extruded products. The motor unit, a stainless-steel design,
features a DC gear motor, piston, switch, battery, and programmer. It's enclosed in a cylindrical
pipe with a locking system. The feed unit, a 70mm stainless steel cylinder, has 252 mm length
and 0.2mm thickness at the bottom. The GI square pipe frame has a horizontal arm and a
vertical arm for support. This motorized equipment is engineered to support large-scale
production, particularly of traditional products such as idiyappam, which are typically labour-
intensive and time-consuming to produce using conventional methods.
By integrating user-friendly and efficient design elements, the new extruder eliminated
many drawbacks associated with traditional extrusion techniques, thereby offering a practical
solution for both medium-scale industrial applications and home use. The machine’s portability
and low energy requirements further enhance its suitability for diverse operational
environments.
In conclusion, the newly developed portable cold extruder represents a significant
technological advancement, providing a cost-effective, efficient, and scalable option for
producing high-quality extruded products. This innovation holds the potential to revolutionize
extrusion processes in various settings, promoting increased productivity and ease of use.
