Resumen:
It accomplished this work with objective to determine the curves of dryness and
moisture of equilibrium hygroscopic of the cake and bran of castor (Ricinus Communis
L.), in order to study the effects of the conditions of dryness and storage about
composition chemistry (purport of oil, moisture, organic matter, ashes and brutish
protein). The cake and bran of castor were dried in temperature of 50, 60, 70 and 80°C,
and thicknesses of one, three and five cm and later kept in three types of packings
(paper, naylon and plastic) for one period of six months, in the climatic conditions from
Campina Grande, PB. The effects in the kinetic of dryness went adjustable in the
models mathematician by Page and Thompson, with delineately experimental two
(materiais) four (temperatures) three (thicknesses) and three (packings) with one whole
of 72 treatments. Of accord with the results got on, looked that with relation the curves
of drynesses, these adjust well on the model mathematician showing coefficient of
determination (R2) high 0,99. In the component chemists valued didn't go met large
alterations, carne just a gain larger of moisture in packings of paper and naylon, at
relation the packing of plastic, it didn't excel 7% the ashes and organic matter staid
without big variations. In relation on the purport of protein, it reduced with increase of
temperature.
