资源简介：
A method and a hydrolysate extracting arrangement in a continuous cooking process for producing pulp， said method comprising the steps of: (e)cooling a content in a prehydrolysis vessel (5a; 5b; 5c; 5d) of a continuous pulp production system such that the content has been cooled down when the content arrives at a hydrolysis outlet (9) of the prehydrolysis vessel (5a; 5b; 5c; 5d) on its way from an inlet (13) provided in one end of the prehydrolysis vessel to an outlet (15) provided in an opposite end of the prehydrolysis vessel; (f)removing a hydrolysate of said content through the hydrolysate outlet (9) of the prehydrolysis vessel， wherein said content in the prehydrolysis vessel is cooled to such a degree that the removed hydrolysate has a temperature between 70°C and130°C.
