Embodiment 1

[0015] (1) The crude process of wood vinegar liquid

[0016] Raw materials: peeled logs of broad-leaved trees such as oak, birch, color, and pagoda tree, tree heads and roots left over from harvesting, cut ends, board bark, and sawdust left over from processing.

[0017] Process: Install the kiln and ignite according to the existing charcoal-making process. When the raw materials are carbonized until yellow smoke comes out of the chimney and the temperature of the smoke reaches 80°C, connect the acid-resistant porcelain tubes in sections 2-5 to the chimney. Use a plastic bucket to collect the wood vinegar solution from the gap at the junction of the acid-resistant porcelain tubes in Sections 1 and 2. When receiving wood vinegar liquid, it is required that the smoke temperature of the chimney in the first section should be controlled at 80-150°C.

[0018] (2) Refining process of wood vinegar

[0019] The crude wood vinegar solution was left to settle for 3 months, the suspend...

Embodiment 2

[0021] (1) The crude process of wood vinegar liquid

[0022] Raw materials: broad-leaved trees such as oak, birch, color, locust tree, etc., coniferous trees such as fir, cypress, pine, etc. peeled logs, felling residues, tree heads, roots, processing residues, truncation, board bark, and sawdust. Process is identical with embodiment 1.

[0023] (2) The refining process of wood vinegar liquid: leave standstill 4 months, refine according to embodiment 1 process.

Embodiment 3

[0025] (1) Crude process of wood vinegar liquid: raw materials are peeled logs of coniferous trees such as fir, cypress, pine, etc., tree heads and roots of felling residues, and truncation, board bark, and saw foam of processing residues. Process is identical with embodiment 1.

[0026] (2) The refining process of wood vinegar liquid: leave standstill 6 months, refine according to embodiment 1 process.

[0027] The biggest feature of the wood vinegar produced by the process of the invention is that it is a pure natural product without any artificial ingredients added. After testing by the Department of Chemistry of Beijing Normal University, the amount of residue on ignition is about 0%, indicating that the content of wood tar in the wood vinegar is basically no. The specific test data are as follows:

Abstract

The production process of pyroligneous liquor includes two steps of crude preparation step and refining step. The material includes barked log of broad-leaved tree and coniferous tree, stump and leftover of wood working. The material is loaded and baked in charcoal kiln, and after yellow smoke emerges and reaches the temperature of 80 deg c, crude pyroligneous liquor is collected through acid resistant ceramic pipe connected to the chimney. The crude pyroligneous liquor is set stand for precipitating for over 3 months, and then filtered gauze and membrane filter to obtain the refined pyroligneous liquor product. The pyroligneous liquor as one kind of natural product without any additive component has wide application.

Description

technical field [0001] The invention relates to a production process of forest products, in particular to a production process of wood vinegar. Background technique [0002] Wood vinegar liquid is the liquid produced by the carbonization process of natural wood and extracted after cooling. It contains acetic acid, wood alcohol, ethanol and other 200 kinds of minerals. It has significant acidifying effect, bactericidal effect, and inhibits the growth of harmful microorganisms side effects. [0003] The methods for producing wood vinegar at home and abroad are simple and crude at present, resulting in poor and unstable product quality, low raw material utilization rate, and poor economic benefits. Contents of the invention [0004] The purpose of the invention is to overcome the defects of the prior art and provide a wood vinegar production process. [0005] This aspect adopts the following technical solutions to realize the object of the invention. [0006] The wood vine...
