TWIN-SCREW EXTRUSION of RICE FLOUR: EFFECT of EXTRUDER LENGTH-TO-DIAMETER RATIO and BARREL TEMPERATURE ON EXTRUSION PARAMETERS and PRODUCT CHARACTERISTICS

Abstract: The effects of extruder length‐to‐diameter (L/D) ratio and barrel temperature on extrusion system parameters and extrudate characteristics during twin‐screw extrusion of rice flour were studied. the L/D ratio and barrel temperature were varied between 16–24 and 75–185C, respectively. the extrusion system parameters studied were thrust bearing pressure and specific mechanical energy. the expansion ratio, bulk density and maximum force of the extruded product, as affected by the L/D ratio and barrel temperature,… Show more

“…A dureza é um dos fatores que determina a aceitabilidade do alimento pelo consumidor [5] e, assim como a fraturabilidade, é desejável que seus valores sejam baixos. Porém, para estas propriedades de textura, não há definição da faixa de valores aceitáveis para "snacks" [23].…”
