Description

[Detailed description of the invention] The present invention relates to a method for activating vegetable humus mud.

11. Humic mud is a fermented plant material that is currently or has been deposited in water such as the seabed and lakebed for many years.

The applicant is the first KIF! J Application No. 55-94563, he filed a patent application for a gas-based deodorizing and sterilizing composition in which vegetable humus mud is forcibly oxidized and dried, but it has even stronger sterilizing and deodorizing properties. We have continued our research with the aim of obtaining a composition with gas adsorption properties. As a result, the activation method of the present invention was discovered. In the first place, it has been known for a long time that vegetable humus mud has all the 4 odor effects to some extent.

The deodorizing power of the dug humus mud as it is varies widely, and it is often found that it has almost no deodorizing effect.

This is a method of simply drying and pulverizing the water-containing mud [4], which is a conventional method.

This alone hardly increases the deodorizing power.

Items that have been piled up in the open and dried in the sun for several months are known to have considerable deodorizing power, but this is only a small part of the surface.

Regarding the deodorizing effect of humus mud, the present inventor has determined that -(: 4'+If
As a result of repeated research, it was discovered that by forcibly oxidizing Fu414 mud, the deodorizing power was enhanced, and at the same time, the gas adsorption and bacteriostatic effects were also strengthened.
No. 94563 is pending, and at that time, it was experimentally confirmed that simply exposing the material to air as an oxidation method was insufficient and had little effect.

Hereinafter, the deodorizing action, gas adsorption, and bacteriostatic action enhancement of HX and 4ti mud will be collectively referred to as activation of humus mud. Regarding the mechanism of activation of humic mud, the composition of humic mud itself is complex, and although many researchers have conducted research for many years, there is still no established theory.

Furthermore, the present inventor has experimentally found that only C is activated by air oxidation in humic mud in a wet state, and that the progress of activation is stagnant in a dry state.

Based on these experimental facts, the present inventors believe that the activation of humus mud involves the oxidation effect of oxygen in the air.

We have come to the conclusion that microorganisms, especially aerobic bacteria, are also involved.

That is, after draining the humus mud and crushing it with a water content of about 70 to 80 yen using a hammer mill-type crusher to bring it into sufficient contact with air, it is pumped up in a plastic greenhouse and left to stand for several days. .

This is called maturing. During this time, ro・
! It is thought that various reactions are carried out by living organisms.

In other words, crushing expands the surface area and increases the contact area with air, thereby ensuring a sufficient supply of oxygen and retaining an appropriate amount of moisture.

The key to activating humus mud is to provide sufficient time for microbial reactions to proceed.

Another important point is that the humus sludge is stirred by crushing and the variation in activity is homogenized.

Therefore, if the crushing step is omitted, the supply of oxygen will not be carried out smoothly, and the humus mud, which inherently has large variations in quality, will not be homogenized.

In addition, water Vl is essential for biological reactions, with at least 50%
On the other hand, if the water content is too high (for example, 90 cm or more), the humic mud becomes pasty and oxygen supply becomes insufficient, which is not preferable.

The preferred amount of water is 50 inches to 80 degrees.

The aging process is carried out at room temperature, and the aging time should preferably be several days, preferably 50 days or more.

Raising the temperature will somewhat accelerate the ripening reaction.

The evaporation of moisture also increases, and if the moisture content falls below 50 degrees, the ripening reaction is likely to stagnate, resulting in incomplete activation. However, even in that case, by spraying water appropriately,
If care is taken to ensure that the moisture content does not always fall below 50%, activation termination T'ftF can be prevented.

Looking at the changes in the properties of humus mud during the crushing process and aging process, it can be seen that the pH decreases and the Brlx degree increases.
HEi will be done. In other words, the pH is neutral CPH = 6 before crushing
．． 5 to 7.0), but gradually decreases through the crushing-ripening process, reaching PH:JQ.

The Brlx degree is around 0.1 before crushing, but it is 0.7 to 1.
It rises to 0 degrees.

(See Table A) As a result, the deodorizing power, gas adsorption, bacteriostatic action, etc. of humus mud are strengthened, that is, activation progresses.

This is the reason why PH and Brlx degree are used as indicators of the activity of humus mud.

Table A: Both crushing and ripening were carried out at room temperature, but the sample temperature during ripening was V130 to X56°C.

To measure the pH, 20J'r of the sample (dry weight) was added to 2001r at room temperature with Imen-exchanged water, immersed and stirred for 30 minutes, and the V solution was measured using a PH meter (Denki Kagaku Keiki Co., Ltd. MO-F type). It was measured with

The degree of Brlx was measured using a Tabo refractometer N-IQ (after zero point adjustment) using tap water.

For comparison, P in the case of only the aging process without the crushing process
Table B shows the change in HBrlx degree.

PH=3. □ The standard activity is Brlx degree = 0.4, but in the case of only the aging process without the crushing process, it is 3
It can be seen that the standard activity is not reached in about 0 days. .

After all, in the crushing process, the contact area with air is increased to ensure sufficient oxygen intake, and the raw materials are thoroughly mixed and homogenized.Then, in the ripening process, the humus mud is activated by retaining an appropriate amount of moisture. Activation is completed by allowing sufficient aging time.

If the crushing step is omitted, the contact area with air will be small, resulting in insufficient oxygen uptake, and if drying is too rapid, aging time will be insufficient, resulting in incomplete activation. This is why the combination of crushing and ripening is the favorite.

After passing through the crushing process and aging process, the product is subjected to the crushing process again.1
Then, when it is subjected to a maturing process, the humus mud is further activated. Even if the water content of the humus mud is 50 ml or more, the activity of the humus mud will improve each time the combination of tir crushing and ripening is repeated, but from a practical standpoint, the limit is three times.

Although repeating this process four or five times takes effort, the improvement in activity is not that great.

The following examples will explain how VC progresses in the activation of humic mud by the combination of the crushing process and the aging process. Ta. This shows how slowly and incompletely the activation progresses if the material is left to air dry without a crushing step.

The degree of activation is determined by PH and Brlx degree.

The activity referred to here refers to the performance that combines the deodorizing power, gas adsorption, bacteriostatic action, etc. of humus mud, and cannot be expressed in numbers, but the lower the pH, the higher the degree of Brx. It has been confirmed that the activity is high.

As a practical standard product, PH=3. Q Br1
It was decided that x degrees = 0.4.
