<p>a) The reaction under pressure, such as cooking or hydrolysis, involves delivering under pressure, by means of a pump, a liquid mixture obtained by diluting substances of vegetable origin with the liquid in the presence of which the intended treatment is to take place. b) Provision is made to subject these substances, in addition to, or with, this dilution operation, to a thorough impregnation with this liquid, for example inside an apparatus (3) for dilution and impregnation. The delivery of the mixture obtained is then carried out by means of a Vortex pump (6) capable of conveying a liquid-solid mixture and driven at a variable speed by means of a control device comprising a flow detector (6a) and arranged so as to keep constant the flow rate in the delivery pipe (10). <IMAGE></p> |
