Preparation of texturized soybeans can be done in simple dispersed facilities with small-size extrusion and screw-pressing equipments—tractor power take-off-driven if necessary. 

Even more highly structured variations on the band structure have been reported, such as the helical coarse rope structure in PEG solutions [18] (Figure 11.18) or a torsad structure in HPC solution [100] and a tractor or herringbone texture in thermotropic polyester [101].
