P. Baptista ; F. Oliveira ; J. Oliveira ; S. Sastry | 1997Average fluid-to-particle heat transfer coefficients were experimentally determined for spherical aluminium particles heated in carboxymethylcellulose solutions. Two situations were considered : a still particle immersed in a moving fluid, and a[...]

P. Baptista ; F. Oliveira ; J. Oliveira ; S. Sastry | 1997In the aseptic processing of particulate fluid foods, the residence time distribution of particles and the fluid-to-particle heat transfer are intimately related to the linear and rotational velocities of the particles. The development of models[...]

P. Baptista ; F. Oliveira ; S. Caldas ; J. Oliveira | 1996Residence time of particles and fluid-to-particle heat transfer coefficient, two of the major unknowns in the aseptic processing of particulate fluid foods, are intimately related with the linear and rotational velocities of the solid particles.[...]

M. Rao ; P. Okechukwu ; P. Da Silva ; J. Oliveira | 1997Granule size and size distribution, measured by laser diffraction, affected the flow behavior at 20° C of (2.6% w/w) corn and cowpea starch dispersions heated for various time intervals above their gelatinization temperatures. The standard devia[...]
