JPH06104114B2 - Odorless powder dry distillation bamboo manufacturing method - Google Patents

Description

Detailed Description of the Invention a. The object of the present invention is to deodorize bamboo plants (hereinafter referred to as “bamboo”) by carbonization,
The purpose is to provide an epoch-making new material having the ability of decolorization, soundproofing, and heat retention.

B. Structure of the Invention The present invention comprises a step of powdering a bamboo plant (hereinafter referred to as "bamboo family") to obtain powdered bamboo, and washing the powdered bamboo with water to wash the extract component contained in the powdered bamboo with water. After that, the method for producing odorless powder carbonized bamboo comprising the steps of draining, extracting the extract component together with water by a squeezing press, and drying the powdered bamboo from which the extract component has been removed, and further carbonizing with a carbonizer. provide.

In addition, in order to make the bamboo material into powder, the bamboo material is cut into a proper size, crushed by a crusher to a uniform width with a bamboo slicing machine, and processed into chips. Bamboo may be powder processed with a powder machine.

In the step of washing the extract component of the powdered bamboo with water, the powdered powdered bamboo may be placed in a water tank and appropriately stirred while simultaneously supplying water and draining water.

After washing, the extract components are completely extracted from the bamboo by draining the water and extracting the extract components together with the water using a squeezing press.

Then, the powdered bamboo from which the extract component has been removed in this way is dried by a dryer and further carbonized by a carbonizer. Then, steam distillation is carried out using a steam type high pressure kettle as the carbonization device according to the following data. Pressure 3K ~ 7K, required time 40 minutes ~ 180
Minute, temperature 110 ° C to 190 ° C Heat source Steam, and the drying device can set the degree of dry distillation and the concentration of dye by changing the pressure, temperature, and required time.

Example (1) Odorless powder dry-dried bamboo was obtained by the method of the present invention using the Moso bamboo excluding the leaves and the data shown below.

Example (2) Deodorizing Effect Agent The deodorizing ability of the odorless powder carbonized bamboo obtained according to Example (1) was confirmed by the following experiment. Prepare 4 sealed plastic containers with a diameter of 700 mm, put the same amount of dried fish (100 g) and miso (100 g) directly into each container, and use the odorless powder dry distillation obtained in Example (1). Bamboo (200 g) and commercially available deodorizing activated carbon (200 g) were separately placed in the same container, sealed and 120 minutes later, the container was opened again and the deodorizing effect in the container was judged by the sense of smell.

It is the degree of the deodorizing effect in the container, and the thinner the odor in the container, the stronger the deodorizing effect is recognized.

Example (3) Example of adsorption effect The adsorption ability of each material was confirmed by the following experiments basically using the same method as described above.

Fully open the aromatic nozzles of the commercially available aromatic plastics in four sealed plastic containers, put one on each container, and obtain the same odorless powder dry-dried bamboo (100g) and commercially available deodorizing activated carbon ( 100 g) individually in the same container,
The container was sealed and 120 minutes later, the container was opened again, and the degree of adsorption of the test material was directly judged by the sense of smell.

It is the degree to which the odor is adsorbed, and it is recognized that the stronger the odor of the test material, the higher the adsorption capacity.

Example (4) Example of decolorizing effect The decolorizing ability of the obtained powder dry-distilled bamboo was confirmed by the following experiment.

Prepare 200 ml of a 0.001% aqueous solution of the legal dye Yellow No. 5 and disperse the beaker in 100 ml portions. 2 gr of powdered dry-distilled bamboo is mixed with one of the preparative solutions, stirred at room temperature for about 5 minutes with a glass rod and allowed to stand. To the other preparative solution, 2 gr of commercially available activated carbon for decolorization is mixed, stirred under the same conditions as above, and allowed to stand. Each of the obtained treatment liquids is passed through a suction furnace through a Bronner funnel (outer diameter 90 mm) lined with qualitative oven paper. Each furnace is divided into two colorimetric colors (capacity: 50 ml), 50 ml of each is weighed, and the degree of decolorization is visually judged.

The results are as follows.

Aqueous solution decolorized with powdered dry-dried bamboo shows a very slight yellow color Aqueous solution decolorized with activated carbon for decolorization A slight yellow color is observed From the above results, it was confirmed that the powdered dry-distilled bamboo has a decolorizing ability.

C. EFFECTS OF THE INVENTION According to the present invention, an extract component can be removed by treating a bamboo material into a powder form and washing with water, and by removing the extract component, deodorization and coloring of the pigment can be performed. The odorless and light-colored powder bamboo can be commercialized as a revolutionary new material having deodorizing, decolorizing, soundproofing, and heat retaining ability by the dry distillation effect and the combined effect of the materials by the powder treatment. There are various uses by selecting the particle size suitable for the use. Also, the fleshy part of the powder-treated bamboo material becomes a fine powder, and the conduit part becomes a fibrous substance,
In addition, the innumerable gaps generated by the combined effect of these two materials can be used for many purposes because they can increase the absorption power of molecules and enhance the immediate effect. In addition, since conventional activated carbon is completely carbonized and is black, black ink adheres to hands and clothes when it is directly touched.However, since the dry-dried bamboo of the present invention is a light color, it does not touch hands and clothes. The ability to deodorize, decolorize, soundproof, and keep warm due to the effect of dry distillation and the combined effect of fine particle material and fiber material produced by powder treatment due to the effect of dry distillation It is an excellent and useful invention.
