Abstract

The invention discloses a bamboo vinegar graded condensation collecting method. The bamboo vinegar graded condensation collecting method comprises following steps: bamboo sheets are subjected to drying and charing, gas generated in bamboo sheet charing process is collected, and is subjected to condensation at different temperatures range from 50 to 250 DEG C, and bamboo vinegar solutions are collected respectively. The bamboo vinegars obtained at a wide temperature range are collected different temperatures respectively, and bamboo vinegar products of different compositions can be obtained; product quality is high; the pertinency is high; requirements of different fields can be satisfied; cost is low; and income is high.

Description

technical field [0001] The invention belongs to the technical field of bamboo vinegar production, and in particular relates to a method for collecting bamboo vinegar by classification and condensation. Background technique [0002] Bamboo vinegar is a liquid substance obtained by collecting the gas produced in the pyrolysis of bamboo during charcoal burning with bamboo, and cooling the gas at normal temperature. Bamboo vinegar contains nearly 300 kinds of natural polymer organic compounds, including organic acids, alcohols, ketones, aldehydes, esters and trace alkaline components, etc. It is widely used in agriculture, medical treatment, chemical industry, food and other fields : [0003] 1. Soil improvement: spraying bamboo vinegar in the soil can prevent the blight of the seeds, and can also be used as a disinfectant for the soil. Applying bamboo vinegar in the soil can effectively inhibit the reproduction of microorganisms that hinder plant growth, and can kill pests su...
