。BSK bacteria was discovered in the soil by the present inventors. It belongs to Bacillus subtilis, is a Durham-positive bacterium that has antagonistic properties against harmful bacteria such as putrefaction bacteria, and is a reducing bacterium. It is similar to Bacillus subtilis, but its properties are different. Under a microscope, they were observed as long chains when singly or in pairs. This BSK bacterium itself has already been applied for as a biopharmaceutical, and was deposited as FIKEN No. 9643 at that time.

整する意義がある。This BSK bacterium can effectively decompose oily bones and cellulose, which are difficult-to-decompose substances that many aerobic microorganisms are not good at, and at the same time has good functionality as an antagonist that controls other putrefactive and disease-causing bacteria. It has been confirmed that (Experiment Example, II) In addition, it is certain that the production of unique enzymes serves as a utility value, considering that decomposition energy exists only in the liquid component of the prepared biowater. This has the significance of producing and adjusting biowater in the bioreactor 2.
バイオ投入器7は、ドラム12の回動により投入口13
からタンク5内のブロック状ACF6に失活状態にある
胞子状のBSK菌を単独でまたは適量の栄養源ととちに
小型モータ14の稼動により放出する構造のものが多く
使用されるが、この構造に限定されるものではない。The bio input device 7 opens the input port 13 by rotating the drum 12.
In many cases, a structure is used in which the inactivated spore-shaped BSK bacteria is released into the block-shaped ACF 6 in the tank 5 either alone or with an appropriate amount of nutrients and then by the operation of the small motor 14. It is not limited to structure.
増殖環境調整器8は、温度調整器15と、空気供給調整

状ACF6の下方に横架させるヒータ17をサーモスタ
ット18の作動により点検操作するようになっている。The growth environment regulator 8 consists of a temperature regulator 15 and an air supply regulator 16. Among them, the temperature regulator 15 is configured to inspect and operate a heater 17 horizontally suspended below the block-shaped ACF 6 by operating a thermostat 18.
他方、空気供給調整器16は前記ヒータ17の下方に横
架せる噴筒19をバイブ20でエアポンプ21に連通さ

させることが主な目的の一つである。The bioreactor 2, which is configured as described above, connects the piping line 3 below the tank 5 and converts tap water into biowater in advance to produce and adjust highly functional biowater for floor cleaning. . One of the main objectives is to produce enzymes based on BSK bacteria and ACF.

生物間のせめぎ合いがあり、また、幾多の予測されない
種類の環境抵抗があり、常に優勢なバランス下でBSK
菌を働かせるため、バイオリアクター内での下準備がポ
イントとなり、低コストなバイオの利用技術といえる。In other words, in the microbial world, there is naturally competition between microorganisms, and there are many unpredictable types of environmental resistance, and BSK always maintains a prevailing balance.
The key is to prepare the bacteria inside the bioreactor in order to make them work, and it can be said to be a low-cost biotechnology.
特に、現今において、厨房の油脂分解、臭気対策用とし
て、バイオ製剤が多く販売されているちのの、それ等は
、事前にバケツ等に希釈し、一定時間放置しなければな
らず、その準備が面倒なことや、流出する部分が多く、
経済性と効果を弱め、コスト的にち使い難いものとなっ
ている。また、その希釈液を床に散布する技術はない。In particular, many biologic preparations are currently on sale for decomposing fats and oils in the kitchen and for odor control, but they must be diluted in advance in a bucket or the like and left for a certain period of time, which requires preparation. There are many troublesome things and parts that leak out,
This reduces economic efficiency and effectiveness, making it difficult to use due to cost. Furthermore, there is no technology for spraying the diluted solution on the floor.
このような情況下にあって、上述したバイオリアクター
2自体の存在意義はあるし、これを厨房の床洗いシステ
ム1に組込むことにも意義がある。Under these circumstances, there is a significance to the existence of the bioreactor 2 itself as described above, and there is also significance in incorporating it into the kitchen floor washing system 1.
ところで、この厨房の床洗いシステム1は、上述のよう

and a power line 29 to automatically control the production, adjustment and supply of bio-water. For example, when the clean water introduced into the tank 5 reaches a predetermined flow rate, a signal is obtained from the water level control valve 11 to turn off the power source for introducing the clean water, and the temperature of the introduced clean water is detected. A signal is received from the thermostat 18 to turn the heater 17 on and off, and a signal from a sensor (not shown) that detects the transparency of the biowater is received to operate the air pump 21 to generate a circulating flow while supplying oxygen from the jet nozzle 19. It also automatically commands the opening of the electromagnetic valve 22 and the operation of the pressure pump 23 upon receiving a signal of a cleaning time suitable for spraying the prepared bio-water onto the kitchen floor. It is. In addition, 30 is a water hose, 31 is a floor, 32 is a drain, and 33 is a restaurant.

を浄化しスカムを分解し、悪臭を消臭する。The bio-water sprinkled in this manner is spread almost evenly over the surface of the floor 31, a portion of which evaporates, and a portion of which flows into the drainage ditch 32. Then, the BSK bacteria and the enzymes they produce adhere to the floor surface and decompose fat, cellulose, and other sludge. In addition, BSK bacteria and the enzymes produced by the BSK bacteria purify the wastewater, decompose scum, and eliminate bad odors in all the drainage system channels connected by the biowater flowing into the drainage ditch 32.
