Abstract

The invention relates to a method for extracting sap and pulping from paper mulberry branches and comprehensively utilizing paper mulberry branches. The method is characterized by including A, cutting raw branches into segments to obtain rough roughage by a stock cutter; B, screening and washing the roughage into fine materials; C, feeding the fine materials into an extraction tank to heat, pressurize and boil, separating the materials from liquid, wherein the separated materials are boiling materials and the separated liquid is boiling liquid; D, feeding the boiling liquid into an evaporation tank to purify and prepare sap of the paper mulberry; E, debarking the boiling materials to a debarking machine, and separating barks from stems; F, pulping by the separated bast and the stems. With adoption of multi-industry comprehensive utilization and conversion of waste resources, waste is made profitably, smog due to air pollution caused by burning the waste outdoors is avoided, production cost is reduced, and utilization rate of the paper mulberry is increased. Meanwhile, a novel way to convert and utilize the paper mulberry at high value is provided, and the method has high economic, social and environmental benefits.

Description

1. Technical field: [0001] The invention belongs to the industries of pharmacy, pulping, papermaking and feed, and in particular relates to a method for comprehensively utilizing twigs by extracting twig paste and making pulp, which is suitable for the comprehensive utilization of twigs. 2. Background technology: [0002] Paper mulberry is a high-protein plant, a traditional Chinese medicinal material, and a high-quality paper-making raw material. my country is rich in paper mulberry resources. With the country's strong support for the development of natural non-grain feed industry, the country has more than 1,000 In the 10,000 mu tree garden, in addition to the leaves being used to produce feed, 15-20 million tons of branches are cut down each year. However, these raw materials are used in small quantities in the fields of pharmaceuticals, pulp and paper, and most of the branches of the tree are Burned by the common people as household fuel, or burned on the spot, or discarde...
