PCT No. PCT/FI93/00411 Sec. 371 Date Apr. 26, 1995 Sec. 102(e) Date Apr. 26, 1995 PCT Filed Oct. 11, 1993 PCT Pub. No. WO94/09202 PCT Pub. Date Apr. 28, 1994A device for use in a pulping process comprises first and second pulping units for processing feed material. A flow path connects the first pulping unit to the second pulping unit for transporting material between the units. The second pulping unit has devices for separating pulped material into a first material component comprising waste matter collected at the bottom of the second pulping unit, a second material component comprising sieved pulped material and third material component comprising unsieved pulped material. The second and third material component are separated from the first material component and are transported as a unitary flow to a primary space. Mixing and sieving devices are located in the primary space for separating the second material component from the first material component. The second material component comprises material which passes the sieving device and the third material component comprises material which does not pass the sieving device. A third material component transfer device transfers the third material component to a pre-sieving for further processing and an outlet assembly transfers the second material component downstream of the sieving device.
