COMPRESSION ANALYSIS OF DEHYDRATED AGRICULTURAL PRODUCTS

摘要: ABSTRACT The textural properties of apple, banana, carrot and potato were experimentally determined by uniaxial compressive tests cylindrical specimens at a constant deformation rate 5mm/min. Compression performed, following air drying, various moisture contents ranging from 0.2 to 6 kg/kg db. performed using universal texture testing machine simple mathematical equations used correlate the maximum experimental stress corresponding strain content. It was shown that decreases as content decreases, until critical 1.8 kg water/kg dry solids. Further removal water tends increase stress. found removed. stress-strain data compression test modelled model, containing parameters such (ow), (dim), elastic parameter (E) vi...
