ABSTRACT:
The present invention relates to the embrittlement of the integuments of small seeds wherein the seeds are cooled by thermal shock in a fluidized bed; cooling is provided by direct injection of a cryogenic fluid flash evaporated in the fluidized bed, forming the fluidization gas in the gaseous state, and recovery of cold by countercurrent circulation of the seeds. The process applies to small oleaginous seeds to facilitate their decortication, and to treatment of impermeable leguminous seeds to favor their eventual germination.
