Abstract
After a thermal treatment the products are subjected to an overpressure treatment of at least 10 seconds. Afterwards, an expansion is effected from the state of overpressure directly to the state of vacuum, wherewith the cells are opened such that the subsequent drying in the vacuum proceeds faster and a porous structure is arrived at.
