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

The processing method of the equal wet carbonization of bamboo wood

Technical field

The invention belongs to bamboo wood processing technique field, the processing method of particularly carbonization again after the sam of a kind of bamboo wood.

Background technology

At present, known bamboo wood carbonation is all directly put in carbide furnace by bamboo wood to process, because bamboo wood is cut down from mountain, unload, transport into factory, be processed into base to carbonization, consuming time very long, unavoidably cause the local of bamboo overall or batch moisture content vary, and carbonization is the physical treatment of a hot and humid high pressure, cause the wood of the bamboo after carbonization uneven color, aberration is large, and aberration is many, Hei Jienei charcoal, has had a strong impact on product quality.

Summary of the invention

The present invention is the above-mentioned shortcoming of customer service, provides the processing method of the equal wet carbonization of a kind of bamboo wood.

For achieving the above object, the technical solution used in the present invention is:

The processing method of the equal wet carbonization of bamboo wood, comprises the following steps:

1. fill basket, bamboo wood is placed in the carbonization basket of hollow out;

2. enter pot, bamboo akebi is crossed suspender and put into pond or saucepan or retort;

3. soak, add clear water and bamboo wood is flooded immersion;

4. take the dish out of the pot, the bamboo wood after soaking is taken out; With carbide furnace soaked only need water emptying, namely complete bamboo wood sam processing technology;

5. enter pot, the bamboo wood after sam is put in carbide furnace;

6. capping, after carbonization bell dense block is tight, open the air bleeding valve of carbonization furnace roof, opens furnace bottom blowoff valve simultaneously;

7. carbonization, accesses Steam Heating by jet chimney, closes gas releasing valve for secondary, when constant temperature and pressure reaches setting value, turn down blowoff valve when temperature reaches setting value;

8. pressure release, in stove, reach carbonization time in constant temperature and pressure situation when reaching setting value, steam off valve also opens air bleeding valve pressure release;

9. take the dish out of the pot, treat that namely open bell taking-up bamboo wood in stove after zero-pressure completes bamboo wood sam carbonization technique.

Described immersion is soak at room temperature or adds heat soaking or Dipping or immersion of pressurizeing.

Described constant temperature is 105 ~ 150 DEG C.

Described carbonization time is 10 ~ 240 minutes.

Described constant voltage, with temperature height setting, be generally 0.015 ~ 1Mpa.

The invention has the beneficial effects as follows: the present invention is first by soaked for bamboo wood, after bamboo wood moisture content entirety roughly balances, carry out carbonization again, make bamboo wood under the environment of abundant moistening thermal conductivity factor increase, be heated evenly, the product colour of carbonization gained is even, fresh and alive beautiful, aberration is little, and aberration is few, reduce or eliminate black joint, interior charcoal, qualification rate is high, reduces product cost.

Detailed description of the invention

Dress basket, is placed in the carbonization basket of hollow out by bamboo wood; (carbonization basket refers to the hanging basket that the patent No. is 201320837953.4, and other hollow out basket also can realize certainly).

Enter pot, bamboo akebi is crossed suspender (namely loop wheel machine etc.) and put into pond or saucepan or retort; (carbide furnace please refer to the high-efficiency carbide furnace of 201110049982.X, and certain vertical retort also can realize).

Soak, add clear water and bamboo wood is flooded immersion;

Take the dish out of the pot, the bamboo wood after soaking is taken out; With carbide furnace soaked only need water emptying, namely complete bamboo wood sam processing technology;

Enter pot, the bamboo wood after sam is put in carbide furnace;

Capping, after carbonization bell dense block is tight, open the air bleeding valve of carbonization furnace roof, steam is discharged from air bleeding valve, opens furnace bottom blowoff valve simultaneously, is flowed out by the steam of partial condensation;

Carbonization, accesses Steam Heating by jet chimney, closes gas releasing valve for secondary, when constant temperature and pressure reaches setting value, turn down blowoff valve when temperature reaches setting value;

Pressure release, in stove, reach carbonization time in constant temperature and pressure situation when reaching setting value, steam off valve also opens air bleeding valve pressure release;

Take the dish out of the pot, treat that namely open bell taking-up bamboo wood in stove after zero-pressure completes bamboo wood sam carbonization technique.

Soak for soak at room temperature or add heat soaking or Dipping or immersion of pressurizeing.

Constant temperature is 105 ~ 150 DEG C.

Carbonization time is 10 ~ 240 minutes.

Claims
