    摘要: A transfer device includes a wet blank transfer mold internally provided with an airtight air chamber, a front face with a recessed matching cavity configured to be sheathed on the outside of a pulp wet blank container and is recessed towards the airtight air chamber. The recessed matching cavity includes several small communicating holes provided respectively in an inner wall of each recessed matching cavity and at the bottom of the recessed matching cavity for communication between the recessed matching cavity and the airtight air chamber. A moving frame parallel to the wet blank transfer mold with evenly spaced vacuum cups, is connected to a back face of the wet blank transfer mold via a guiding mechanism. A driver connected between the back face of the wet blank transfer mold and the moving frame to drive the moving frame to move relative to the wet blank transfer mold.

    摘要: The invention relates to a system of producing MFC (micro fibrillated cellulose) having a process device (30) of a pulper, a refiner or a screen configured to process MFC suspension to consistency of 0.5-5%. The system has a continuous pressing means (15; 25, 26) configured to dry the MFC suspension to a consistency of 6-60%. A method of producing MFC has at least one process stage (30) which processes a MFC suspension to a consistency of 0.5-5% by a process device (30). In the process stage the MFC suspension is pulped in a pulping stage in a pulper and/or refined in a refining stage by a refiner and/or screened in a screening stage by a screen. The MFC suspension having the consistency of 0.5-5% is dried in a drying stage of continuous pressing (15, 25, 26) by continuous a pressing device (15, 25, 26) to a consistency of 6-60%.
