Method for preparing pulp using fresh palm empty fruit bunch and equipment thereof

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...

Problems solved by technology

[0004] The purpose of the present invention is to provide a fresh palm fruit bunch pulping preparation technology to overcome the large water consumption and the inability to effectively remove residual fruit particles and non-fibrous skin components wrapped in raw materials. The method and equipment used for pulping and preparing materials for empty fruit bunches can effectively remove the residual oil, residual fruit particles and non-fibrous skin components in the fiber raw materials of palm fruit bunches, which are unfavorable to pulping, so as to reduce the water consumption and chemical consumption of subsequent pulping. reduce product consumption, and improve the quality and papermaking performance of the produced pulp
