Description

The present invention relates to a method for manufacturing bath materials.

In the enzyme bath, a fermented liquid obtained by fermenting rice bran, plants, etc., is added to sawdust, wood chips, etc., and the body is buried in a heat-dissipating material obtained by fermentation. Enzyme baths have become a hot topic for their far-infrared effects and efficacy, and are attracting attention from the aspect of beauty and health promotion.

Enzyme baths use raw raw materials such as sawdust, so if proper management is not performed in the production and maintenance of the baths, pests and putrefaction are likely to cause offensive odors. In addition, in order to raise the temperature of the bath materials for the enzyme bath to the appropriate temperature for warm baths, experienced and skilled craftsmen finely adjust the raw materials and the amount of water according to the external environment such as temperature. , there was a lot of trouble in managing the enzyme bath.

Therefore, various measures have been taken to facilitate the management of the enzyme bath.
For example, Patent Document 1 discloses an enzyme bath having a two-layer structure consisting of an upper aerobic fermentation layer heated to 50-65°C and a lower anaerobic fermentation tank heated to 40-45°C. This eliminates the need to periodically stir the whole bath agent or replace the whole bath agent periodically, making it easier to manage the bath and realizing resource saving.

Also, a footbath that applies the above-mentioned enzyme bath technology has been devised. For example, Patent Literature 2 discloses a foot warmer using enzymatic heat, which is used by inserting both lower legs into a container containing sawdust-based fermentation raw materials. Further, Patent Document 3 discloses an enzyme hotbed agent containing rice bran as a main component and an enzyme footbath using heat generated by a thin heater.

When manufacturing a bathing material with a small amount of raw materials, there is a problem that the temperature is difficult to rise due to heat radiation. By setting the raw materials in the above compounding amounts and increasing the maximum exothermic temperature to 80° C. or higher, it is possible to obtain a bathing material capable of maintaining a temperature suitable for hot bathing even if it is manufactured in a small volume.

In the present invention, "maintaining the temperature" means maintaining the power to raise the temperature to a certain temperature (for example, 60°C or higher). The temperature of the bath material changes according to the time of day, so even if the temperature falls below the specified temperature within a certain period of time, the material is stirred and mixed with air without replacing the material. If it has the ability to generate heat above the specified temperature again, it is judged to have temperature sustainability.

After each raw material is added, it is preferable to mix the raw material with bare hands so that the water content spreads evenly. As a result, indigenous bacteria adhering to the hands can be adhered to the raw material.

Furthermore, it is preferable to ferment with the box partially open. As a result, spoilage of the mixture due to dew condensation during fermentation can be suppressed. Specifically, it is sufficient that a part of the box, such as the upper part and the side part, is opened. In the present invention, fermentation is preferably carried out with the top of the box open.

Moreover, in the main fermentation step S12b, it is preferable to shake the container every 24 hours to mix air into the mixture. Thereby, fermentation heat can be released stably.

After completion of fermentation, when heat is released stably, the resulting mixture can be used as a bathing material. The bath material can be used immediately after production, or can be stored by closing the container with an air-permeable lid or the like, or by closing the mouth of the bag and leaving it in a cool, dark place. The cooled bathing material can be reheated by (3) reheating of the bathing material, which will be described later.

In a preferred embodiment, the amount of water to be introduced in the mixing step S11 is kept constant, and the amount of water to be introduced is adjusted according to the temperature and relative humidity of the external environment in the main fermentation step S12b. This facilitates adjustment of the water content.

When the amount of water to be introduced in the mixing step S11 is constant, the amount of water to be introduced in the mixing step S11 is the total mass of the raw materials (100% by mass) under the condition that the temperature of the external environment is 20 ° C. or higher and lower than 30 ° C. On the other hand, it is preferably 5 to 30% by mass, more preferably 15 to 30% by mass, still more preferably 18 to 20% by mass.
By setting the amount of water introduced in the mixing step S11 within the above range, the amount of water is not excessive, and the microorganisms can be activated in the subsequent fermentation step S12 to release sufficient fermentation heat.
In this case, it is preferable to add the required amount of water including the microorganism-containing liquid in the mixing step S11, and to add the amount of water according to the external environment in the main fermentation step S12b.

When using a container, the preferred embodiment incorporates the description of (1) above.

(3-2) Re-fermentation step S32
In the re-fermentation step S32, after the re-mixing step S31, the resulting mixture is allowed to stand still to generate heat. The re-fermentation step S32 is preferably performed in two steps, a preliminary fermentation step S32a and a main fermentation step S32b.

For details of preferred embodiments of the preliminary fermentation step S32a, the description of the preliminary fermentation step S22a in (2-2) above is incorporated.

By carrying out the reheating step, even if the bath material has been cooled to 50° C. or lower once, it can be heated by a simple method.

Moreover, the bath material obtained by the production method of the present invention can be used multiple times by performing maintenance work such as replacing a part of the material with new raw materials and performing heat generation treatment again.
In the maintenance work, part of the bath material is discarded, and the discarded mass, cypress sawdust and rice bran are mixed in equivalent amounts, and heat treatment is performed again. In the exothermic treatment, it is preferable to further add a microorganism-containing liquid.

In such a case, in the description of (3-1), "parts by mass for 100 parts by mass of the cooling bath material" shall be read as "parts by mass for the total amount of 100 parts by mass of raw materials to be mixed".
Also, the heat generation process in the maintenance work can be performed in the same procedure as in (3-2) above.

The bath material obtained by the production method of the present invention can be used for enzyme baths.
Further, according to the manufacturing method of the present invention, bath materials can be manufactured in small units of about 30 to 40 kg. As a result, even if one does not have equipment such as a large-capacity pool for the enzyme bath or a dedicated device for stirring the ingredients, the required amount of the enzyme bath can be easily produced.

In addition, the resulting small-volume bathing material can be used as a bathing material for use on a part of the body such as a hand or footbath. Specifically, by putting the manufactured bath material in a heat insulating box and putting your hands or feet in it, you can enjoy a warm bath with the heat of natural fermentation.

Normally, in the enzyme bath, the temperature of the bath material changes every 24 hours depending on the state of microorganisms. Furthermore, when the raw material is fermented from scratch to obtain the bathing material, it takes 24 hours or more until the temperature becomes stable enough to be used as the bathing material. Therefore, in the case of an enzyme bath that utilizes only the heat of natural fermentation, it has been difficult to immediately raise the temperature of the enzyme bath according to the needs of customers.

However, by using the production method of the present invention, the produced bath material can be cooled and stored, and immediately reheated and used when necessary. Therefore, the required amount of bath materials can be quickly prepared according to the customer's request. As described above, according to the production method of the present invention, it is possible to adjust the desired temperature by the naturally generated fermentation heat without using an external heater such as a boiler, and furthermore, the generated far infrared rays warm the body. Since it can be heated from the inside, it is possible to provide an enzyme bath with higher customer satisfaction.
