That is, when food waste is fermented with microorganisms in the fermenter, an odor is generated in the food waste. At this time, the concentration of the odor is measured with an odor sensor, and if the concentration is higher than a predetermined concentration, the opening/closing valve of the microorganism storage tank is opened.

Then, while the outlet fan is rotated, the microorganisms accommodated in the microbial storage tank are forcibly introduced into the fermenter through the outlet, and accordingly, a predetermined amount of the microorganisms are supplied in the fermenter.

However, in Patent Document 1 as described above, the odor concentration generated during fermentation is mixed with the odor generated while the food waste decays and the odor generated during fermentation by microorganisms, and the odor concentration is rapidly increased, and it is difficult to separately measure only the odor concentration generated during fermentation. It is difficult to calculate the amount of microorganisms accommodated in the inside, and the error range for calculating the amount of microorganisms is rapidly increased, so it is not possible to accurately determine the amount of microorganisms. , it is difficult to supply air in proportion to the amount of microorganisms in the fermenter, so there is a problem in that the microorganisms are killed in the fermenter. .

The microbial liquid fermentation type food waste processor according to the present invention configured as described above is used as follows.

First, water and food mixed with each other are simultaneously supplied into the crusher 100 , and in this state, a lid (not shown) is covered and sealed on the top of the crusher 100 .

Then, the food falls downward from the inner space of the first housing 110 of the crusher 100, and the water is discharged to the outside of the first housing 110 through the first drain pipe 112, and the food and water is separated.

And, the switch 111a is pressed by a lid (not shown) covered by the inlet 111 of the first housing 110, and accordingly, the switch 111a sends a signal to the motor 120. As the motor 120 is rotationally driven by transmission, the grinding blade 130 is rotated in the forward or reverse direction.

In addition, the switch 111a transmits a signal to the driver 220 to operate the driver 220 .

At this time, the food falling down the first housing 110 is continuously pulverized to have a predetermined size by the pulverizing blade 130, and then, the pulverized material input pipe through the outlet 113 formed at the same height. (300) is supplied.

Here, the pulverized food supplied to the pulverized material input pipe 300 is moved in the direction of the decomposition treatment device 200 through the pulverized material input pipe 300, and then at one end of the pulverized material input pipe 300. It is discharged into the decomposition treatment device 200 .

At this time, a u-trap (unsigned) is formed at one end of the pulverized material input pipe 300, and an excessive amount of food is prevented from falling into the stirring unit 210 by the u-trap (unsigned).

Then, when the pulverized food falls into the stirring unit 210 , the food is supported by the sieve 211 of the stirring unit 210 and accommodated in the stirring unit 210 .

At this time, the stirring unit 210 accommodates the pulverized food and aerobic microorganisms in the sieve 211 at the same time.

And, the stirring shaft 212 installed in the stirring unit 210 rotates the stirring blade 213 while rotating in the forward or reverse direction by the actuator 220 operated by receiving the signal input from the switch 111a. Thus, the stirring blades 213 agitate the food and aerobic microorganisms supported by the sieve 211 .

At this time, the food stirring state in the stirring unit 210 can be visually confirmed through the confirmation window 202a of the closing cover 202 .

Here, the aerobic microorganisms stirred by the stirring blades 213 are fermented in liquid phase while decomposing the food in the pulverized food, and accordingly, the odor and the discharged water are simultaneously discharged from the food.

At this time, the odor sensor 400 installed above the stirring unit 210 detects odors generated in the food and moving upward, and calculates the odor concentration value generated in the food.

Here, the odor sensor 400 measures odor gas generated as food that has not been liquid-fermented in the stirring tank 210 decays, and determines whether aerobic microorganisms in the stirring tank 210 are killed.

That is, when the concentration of the odor moving to the upper part of the stirring tank 210 is increased, the aerobic microorganisms in the stirring tank 210 are killed, and it is determined that liquid fermentation is not performed, and if the concentration of the odor is lowered , it is determined that the liquid fermented food waste is fermented while the aerobic microorganisms in the stirring tank 210 are active, and it is determined whether the aerobic microorganisms in the stirring tank 210 are killed.

In addition, the water quality sensor 500 installed in the lower portion of the stirring unit 210 is discharged from food and included in the discharged water falling to the lower portion of the stirring unit 210 through the passage hole 211a of the sieve 211. Alternatively, it is calculated by measuring the BOD concentration value.

At this time, the water quality sensor 500 is installed in the storage tank 201a of the second housing 201 or installed in the second drain pipe 201b, and measures the COD or BOD concentration value contained in the discharged water.

That is, by comparing and calculating the reference concentration value input to the odor sensor 400 and the measured odor concentration value, when the odor concentration value measured by the odor sensor 400 exceeds the reference concentration value, the display unit 221 ) to inform whether there is a shortage of aerobic microorganisms.

In addition, by comparing the COD or BOD concentration value input to the water quality sensor 500 and the measured COD or BOD concentration value, the COD or BOD concentration value measured in the water quality sensor 500 is the reference COD or BOD concentration value. When the concentration value is exceeded, it is notified whether the aerobic microorganism is insufficient through the display unit 221 .

At this time, the water quality sensor 500 falls downward through the sieve 211 of the stirring tank 210 and measures the COD or BOD concentration value contained in the discharged water stored in the storage tank 201a, and this measured value When it falls below this reference concentration value, it is determined that aerobic microorganisms requiring COD or BOD (oxygen demand) in the stirring tank 210 actively ferment the food waste in the liquid phase in the stirring tank 210, In addition, when the COD or BOD concentration value is measured and the measured value rises above the reference concentration value, it is determined that the aerobic microorganisms requiring COD or BOD (oxygen demand) have died in the stirring tank 210. .

In particular, the water quality sensor 500 measures the COD or BOD concentration value contained in the discharged water, and when the COD or BOD concentration value gradually decreases, the stirring tank 210 corresponds to the COD or BOD concentration value lowered. ), it is judged that aerobic microorganisms grow in

On the other hand, when the COD or BOD exceeds the reference date and time when the COD or BOD reference concentration value input to the water quality sensor 500 is exceeded, the display unit 221 notifies whether the secondary aerobic microorganisms are insufficient.

For example, when the COD concentration value measured by the water quality sensor 500 is 1,400 mg/L or more, and the BOD concentration value is 2,900 mg/L or more, the display unit 221 indicates whether the microorganisms in the stirring unit 210 are insufficient. First notification, and then, when the concentration values of COD or BOD are 1,400 mg/L and 2,900 mg/L, respectively, exceeding the reference time (eg, 8 to 9 hours), the lack of microorganisms in the stirring unit 210 It is a secondary notification of whether or not

Here, from the point in time when the odor concentration value measured by the odor sensor 400 exceeds the reference concentration value or the COD or BOD concentration value measured by the water quality sensor 500 exceeds the reference COD or BOD concentration value, When the reference time is exceeded, the automatic microorganism input device 230 is operated to supply the aerobic microorganisms to the stirring unit 210 of the decomposition treatment device 200 .

At this time, the amount of aerobic microorganisms supplied to the stirring unit 210 by the automatic microorganism feeding device 230 corresponds to the odor concentration value and the COD or BOD concentration value exceeding the reference concentration value.

That is, the amount of aerobic microorganisms supplied to the stirring unit 210 is adjusted according to the odor concentration value and the COD or BOD concentration value measured by the odor sensor 400 and the water quality sensor 500 .

And, the amount of aerobic microorganisms supplied to the stirring unit 210 is displayed through the display unit 221, and the user confirms from the outside.

In the above, the waste water is discharged while liquid-fermenting the food waste in the stirring tank 210, but the COD or BOD concentration value contained in the discharged water is measured for a reference time to determine whether aerobic microorganisms in the stirring tank 210 are killed During the determination, by inserting the bypass member 100a into the first housing 110 of the crushing device 100 so that the bypass member 100a is located at the lower end of the first drain pipe 112, the The water flowing in through the inlet 111 is blocked by the bypass member 100a and bypassed through the first drain pipe 112, so that water falls into the stirring tank 210 of the decomposition treatment device 200 it is prevented

Then, the discharged water discharged from the food is stored in the storage tank 201a, and then discharged to the outside of the second housing 201 through the second drain pipe 201b communicating with the storage tank 201a.

Thereafter, the food is continuously pulverized in the pulverizing device 100 by the same method as above, and the pulverized food is supplied to the agitator 210 of the decomposition treatment device 200, and the food is converted into aerobic microorganisms while stirring. Liquid fermentation is used to break down food.

In the above, for example, the motor 120 and the driver 220 are connected to the switch 111a to operate the motor 120 and the driver 220 by pressing the switch 111a. Although described, the motor 120 and the driver 220 may be operated by a user's manipulation, may be operated with a predetermined time difference, or may be controlled to operate at a predetermined time.

As described above, while stirring the food with the stirring unit 210, liquid fermentation is performed with aerobic microorganisms so that the odor and discharged water are discharged.
