The relevance of the study is due to problem that characteristic various types screw press structures, which leave up 16% oil in cake when pressing sunflower oil. In this regard, purpose find rational methods improve design twin-screw extrusion presses increase yield. leading for solving are empirical research allow comprehensively considering stages improving geometric configuration shaft base...

Peat is a highly contentious input in agriculture. Replacing or reducing peat by substitution with lignocellulosic biomass processed into fibre twin-screw-extrusion could contribute to more sustainable agriculture regard horticultural production. Therefore, plant wastes including pruning from Olea europaea L. and Vitis spp. L., residues perennial herbs like Salvia Populus forest were for replac...

Starch is one of the most used polysaccharides in formulation Edible Films (EFs). This work aimed to develop starch-based EFs employing extrusion technology as a pretreatment casting technique and evaluate storage relative humidity (RH) effect determine their possible application food coating. Corn starch mixture plasticizers (sorbitol glycerol) were processed twin-screw extruder. The was for f...

In this study, we investigated the mechanical properties and inner structure of films linear low-density polyethylene (LLDPE) It was re-pelletized by a twin-screw extruder equipped with without molten-resin reservoir (MRR) different extrusion conditions. The thin sample (thickness: 0.1 mm) were prepared compression moulding machine then their analysed tensile test XRD, Imaging FT-IR, AFM RAMAN ...

The significant increase of Waste Electric and Electronic Equipment (WEEE) has led to an important research in upgrading recycled engineering plastics by means of a blending technique. Classical twin-screw extrusion is compared to a new blending technique, where two polymers are combined together and then flow in several static mixers. This technique allows to obtain different morphologies of c...

Through a twin-screw extrusion process the native structure of sunflower oil cake was completely transformed (globular protein denaturation/texturization and husk fiber defibration) into a simpler matrix-fiber structure, as could be seen on SEM micrographs. Further chemical reduction of protein disulfide bridges greatly reduced the melt viscosity of the moistened composite that it could be inje...
