Example Embodiment

[0034] Examples:

[0035] Fresh palm empty fruit bunches are first sent to the toothed roller squeeze crusher by a belt conveyor. The squeezing and tearing effect of the upper and lower toothed rollers are used to make the mature and unshed palm fruit pieces on the palm fruit bunch fall off, and then sent to the rollers. A conveyor is used to make the fallen palm fruit particles and some of the debris fall from the gap between the rollers of the roller conveyor (the gap width is 30mm) to the lower collection belt conveyor to remove the fallen palm fruit particles, Peel and crumbs. The palm fruit bunch on the roller conveyor is then sent to the slicer for cutting (cutting specifications are 3-6cm, the slicer can choose a grass cutter), and the cut fruit bunch fibers are then squeezed by a double screw extruder (compression) The ratio is 4:1), to remove part of the free water and residual grease in the palm fruit bunch, and at the same time use the mutual squeezing and kneading ef...

Abstract

The invention relates to a method for preparing pulp using fresh palm empty fruit bunches and equipment thereof. The method is characterized in that procedures of squeezing tearing, threshing, cutting, double screw extrusion, finishing sorting and the like are conducted on the fresh palm empty fruit bunches to effectively remove non-fiber components of free water, non-fiber peels, residual fat, fruit grains and the like in the palm fruit bunches, and adverse influences of the non-fiber components on pulp preparation in subsequent pulp preparation process can be significantly reduced. By meansof the method, the quality of palm fiber raw materials can be greatly improved to achieve the purposes of the reduction of ineffective consumption on chemical products of non-fiber components of the raw materials in the pulp preparation process and the improvement of the quality of paper pulp.

Description

technical field [0001] The invention belongs to the technical field of pulping and stock preparation, and in particular relates to a method for pulping and stock preparation of fresh empty palm fruit bunches and used equipment. Background technique [0002] Oil palm is an important economic crop in Southeast Asian tropical regions such as Malaysia and Indonesia. The annual output of palm empty fruit bunches (EFB, empty fruit bunches) after threshing reaches about 40 million tons. For a long time, empty palm fruit bunches have been mainly treated as waste, either incinerated, or piled up in an open space to let them ferment and rot naturally, which not only caused a great waste of fiber resources, but also caused environmental pollution. Since palm fruit bunches need to be steamed and then threshed, the empty fruit bunches after threshing are basically in a state of saturated water absorption (moisture content exceeds 80%), and a certain proportion of palm oil is adsorbed; T...
