Wood fiber manufacturing method

Abstract

The invention discloses a wood fiber manufacturing method. The wood fiber manufacturing method comprises the following steps of selecting corn stalk husk and fast-growing poplar as raw materials; cutting the raw materials into strips with the thickness of 2 cm and the width of 2 cm and the appropriate length in the range adaptive to a hydraulic machine; soaking the cut wood strips in a wood soaking solution for 6 to 10 hours; drying flattened and soaked wood by adopting hot air; and crushing the dried raw materials in a fiber crushing machine and screening through bottom screens by rubbing androlling under the actions of high-strength friction force, shear force and impact force of the fiber crushing machine, so that the wood fibers with the length-to-diameter ratio of 3 to 7 can be obtained according to the screens with different specifications. According to the wood fiber manufacturing method, the corn stalk husk and the fast-growing poplar are selected as the raw materials; dryingcharacteristics of the wood fibers and a process control method are provided; wood can be effectively softened by adopting the wood soaking solution provided by the invention, so that the wood fibersare kept intact; high-quality wood fibers are prepared by matching optimal process parameters; and the wood fiber manufacturing method is energy-saving and environment-friendly, and has popularizationand application value.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood fiber production method. Background technique [0002] Wood fiber drying is the link that consumes the most energy in the production process of wood products. The energy consumption of wood fiber drying equipment accounts for about 45%-60% of the total energy consumption of product production, and the drying efficiency is low. Traditional fiber drying methods will be gradually eliminated or transformed, so exploring a low-energy, fast, and environmentally-friendly drying technology that makes wood fibers highly dispersed meets the requirements of efficient utilization of biomass resources and the development of low-carbon circular economy today. [0003] The traditional methods of wood fiber drying include hot air circulation oven drying, drum drying, pipeline air drying, infrared radiation drying and microwave drying. Hot air circulation oven drying is a wood fib...

Problems solved by technology

[0005] Judging from the current situation and development trend of fiber drying equipment at home and abroad, whether it is the traditional wood fiber drying technology with high energy consumption and low drying efficiency, or the new drying technology that has developed to a certain extent within their respective scope of application, it has not yet been completely solved. Key technical issues such as large equipment area, high energy consumption, and poor dispersion of dry materials
