Effect of particle size and humidity on sugarcane bagasse

The efficiency of biomass combustion process is affected by the particle size and moisture content The thermal decomposition of wood residues in form of blocks [8] and log [9] has shown that increasing the particle size causes an overlapping during the stages of drying pyrolysis and char oxidation thereby increasing the burning times

Apr 01 2015When a particle is subjected to higher drying rates the evaporation of moisture is rapid and promotes the formation of a hard crust that does not allow particle shrinkage during spray drying However if the inlet temperature is lower the particle remains moist for a longer period of time and shrinks thus decreasing its size [39]

dryer The effect of drying temperatures on the particle size was evaluated for the powder form as well as after reconstitution in distilled water to the original solids content following a multilevel factorial design with variation of the inlet (180– 210 C) and outlet (75–105 C)

The aim of this study was to investigate the effect of preparation method and particle size on digestion of starch in fresh and dry pasta types Pasta samples were boiled refrigerated and re-heated with samples collected after each stage and then prepared as small (2 mm) and large (5 mm) particles for sub Food Function Recent Open Access Articles

There is a substantial increase in the enhancement of thermal conductivity as temperature increases At 55 C this value increases to around 16 % The thermal conductivity enhancement decreases from (30 to 10) % while the particle size increases from (10 to 35) nm but enhancement increases when the particle size is above 35 nm

Effects of three spray-drying process parameters on particle morphology and particle size distribution were evaluated: 1) gas flow rate 2) liquid feed rate and 3) suspension solids concentration Particle morphology was characterized by scanning electron microscopy (SEM) and a morphology analyzer

the cooking temperature the cooking time and the texture of the endosperm of the grain However they don't highlight the interaction effects of temperature and time of cooking on the digestibility The hypothesis test is that the effects of particle size and cooking conditions used could significantly improve the starch digestibility of

requirements Among these particle size distribution is one of the most important and easiest to control In this work we examine the effect of a particle size distribution (PSD) on sintering behavior by isolating it as the sole variable during sintering Much is known about the effects of PSDs on sintering

Oct 02 2016In this section the effects of these parameters on the particle temperature and moisture content are assessed Moreover the effects of size distribution on the drying rate and the heat loss are discussed and finally the temperature distribution of particles in different instances during drying are visually exhibited 4 1 Computational
