Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing bamboo vinegar powder.
[0002]
[Prior art]
Bamboo vinegar is a by-product obtained by collecting and condensing volatiles mainly composed of acetic acid generated in the kettle when bamboo material is steamed in a kettle to produce bamboo charcoal, and various types of acetic acid, alcohols, etc. Contains the active ingredient.
[0003]
Bamboo vinegar has effects such as disinfection, anti-inflammation, softening of keratin on the skin surface, activation of skin cells, etc., and is widely used in bath salts, cosmetics, soil improvement aids, deodorants, preservatives, etc. .
[0004]
Patent Document 1 discloses a method for producing a bamboo vinegar solution.

[0006]
[Problems to be solved by the invention]
In the prior art, bamboo vinegar is used as a liquid, and has the following problems.
(1) When used as a bath additive, the amount used for a single dose is measured with a measuring instrument, which is inaccurate, and it is difficult to obtain a stable bathing effect. is there.
[0007]
{Circle around (2)} When used as a cosmetic such as soap, shampoo, rinse, etc., the volume becomes large, there is difficulty in adjusting the concentration, and it is difficult to produce small quantities.
[0008]
(3) When used as a soil improvement aid, deodorant, or preservative, it is difficult to dilute the undiluted solution of bamboo vinegar to obtain a diluent of a required magnification (generally 10 to 1200 times). The dilution concentration may be wrong.
[0009]
{Circle over (4)} The liquid bamboo vinegar has 90% or more of water, and therefore has poor transport efficiency and storage efficiency, and may be rotten due to long-term storage.
[0010]
An object of the present invention is to improve the usability and handleability of a bamboo vinegar solution by pulverizing the bamboo vinegar solution.
[0011]
[Means for Solving the Problems]
The invention of claim 1 includes a step of purifying the bamboo vinegar, a step of introducing a seed of a crystal made of a carbohydrate compound into the purified bamboo vinegar, and crystallizing the bamboo vinegar, This is a method for producing bamboo vinegar powder, which comprises a step of spray-drying the liquid to form a powder.
[0012]
According to a second aspect of the present invention, in the first aspect of the present invention, the seeds of the crystals are wheat flour.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a process diagram showing a manufacturing process of bamboo vinegar powder.
[0014]
The substance is generally soluble (eg, 35 g of salt in 100 cc of water), and precipitates or crystallizes when the concentration of the solution exceeds the solubility (eg, when salt water is concentrated to high concentration, water evaporates and excess salt is added). However, the bamboo vinegar solution does not precipitate or crystallize even if it is concentrated by distillation.
[0015]
Therefore, in the present invention, the bamboo vinegar liquid is powdered by the following method, and bamboo vinegar powder can be produced (FIG. 1).
(1) The bamboo vinegar solution obtained during the production of bamboo charcoal is allowed to stand and refine for at least 6 months.
[0016]
(2) The bamboo vinegar solution obtained in the process of producing bamboo charcoal or the bamboo vinegar solution which has been statically purified in the above (1) is purified by distillation.
[0017]
(3) Into the bamboo vinegar liquid purified in (1) and / or (2) above, wheat flour (other carbohydrate compounds such as rice flour, starch, etc.) are introduced as crystal seeds, and bamboo vinegar is added. The liquid crystallizes.
[0018]
(4) The crystal of the bamboo vinegar liquid crystallized in the above (3) is spray-dried, and the crystal is pulverized to obtain a high-purity bamboo vinegar powder.
[0019]
In the spray drying, the crystal of the bamboo vinegar is atomized by centrifugal spraying or nozzle spraying, the evaporation area is rapidly increased, and clean hot air is introduced for almost instantaneous drying.
[0020]
The bamboo vinegar powder thus produced can be widely used as a bath additive, a cosmetic agent, a soil improvement aid, a deodorant, a preservative, and the like.
[0021]
According to the present embodiment, the following operational effects can be obtained.
{Circle around (1)} After the bamboo vinegar solution is subjected to stationary purification for at least 6 months and / or concentrated by distilling and purifying, a carbohydrate compound is introduced into the bamboo vinegar solution as a crystal seed to obtain the bamboo vinegar solution. Can be easily crystallized. Further, by spray-drying the crystallized bamboo vinegar solution, a high-purity bamboo vinegar powder can be obtained.
[0022]
{Circle around (2)} As the carbohydrate compound used as a seed for the crystal, wheat flour is most suitable, and rice flour, starch and the like can also be used.
[0023]
(3) When bamboo vinegar powder is used as a bathing agent, a solid, granular, or capsule-shaped bathing agent can be easily produced, and a single use amount can be simply packaged. Therefore, the amount of use for one time can be accurately fixed, and a stable bathing effect and the like can be obtained. It does not stain like a liquid even if it touches the user's hand.
[0024]
(4) When the bamboo vinegar powder is used as a cosmetic such as soap, shampoo, rinse, etc., the volume is small, the concentration can be easily adjusted, and it can well cope with small-quantity production.
[0025]
5) When using bamboo vinegar powder as a soil improvement aid, deodorant, or preservative, first prepare the required amount of water, and then add a certain amount of powder to it to obtain the desired concentration of bamboo vinegar. A diluent can be easily obtained.
[0026]
{Circle around (6)} By using bamboo vinegar powder, transport efficiency and storage efficiency are improved as compared with liquid, and there is no possibility of spoilage even after long-term storage.
[0027]
The embodiments of the present invention have been described in detail above. However, the specific configuration of the present invention is not limited to the embodiments, and the present invention is applicable even if there is a change in a range that does not depart from the gist of the present invention. include. For example, the bamboo vinegar powder produced according to the present invention may be used alone as a bathing agent or the like, or as a mixture with other substances.
[0028]
【The invention's effect】
As described above, according to the present invention, the bamboo vinegar solution can be powdered, and the usability and handleability of the bamboo vinegar solution can be improved.
