Processing method for bamboo moisture equilibrium carbonization

Abstract

A processing method for bamboo moisture equilibrium carbonization includes the following steps of basket loading, furnace feeding, soaking, furnace discharging, furnace feeding, cover sealing, carbonization, decompression and furnace discharging, and the bamboo moisture equilibrium carbonization process is completed after a furnace cover is opened to take out bamboo when pressure in a furnace is zero. The method has the advantages that bamboo is soaked in water first and carbonized after the moisture content of the bamboo is approximately balanced in whole, the bamboo is evenly heated under the environment where the bamboo is fully moisturized and the heat conductivity coefficient is increased, products obtained through carbonization are uniform in color, fresh, attractive, low in chromatic aberration and small in chromatic aberration quantity, black joints and inner carbon are reduced or eliminated, the percent of pass is high, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of bamboo and wood processing, in particular to a processing method for carbonizing bamboo and wood after they are wetted. Background technique [0002] At present, the known carbonization of bamboo and wood is to directly put the bamboo and wood into the carbonization furnace for processing. Since the bamboo and wood are felled from the mountain, unloaded from the mountain, transported into the factory, processed into blanks and carbonized, it takes a long time and inevitably causes bamboo The moisture content of local or overall or batches varies widely, and carbonization is a physical treatment of high temperature, high humidity and high pressure, which leads to uneven color of bamboo and wood after carbonization, large color difference, many color differences, black knots and internal charcoal, which seriously affects the product. quality. Contents of the invention [0003] In order to overcome the ab...
