<Conventional Technology and Problems> Food and drink consumed by humans generally undergoes putrefaction and fermentation by microorganisms. Putrefaction is harmful to humans, but fermentation provides benefits to humans because it improves metabolism.

Therefore, humans intentionally ferment and consume food and drinks as much as possible. The types include kimchi, which is a typical Korean side dish, as well as fermented foods such as bread and amazake, and the reality is that they are always consumed in the diet.

Since the main ingredients of the above kimchi are vegetables, it contains vitamins, minerals, etc., and the various organic acids contained in such vegetables are very important as a side dish that promotes appetite. It is something. The lactic acid bacteria produced during the fermentation of kimchi inhibit the growth of various harmful bacteria in the body, making it an extremely good fermented food that is indispensable as a side dish.

Traditionally, kimchi was produced at each household level.

As industrialization gradually progressed, vegetables such as Chinese cabbage were constantly supplied in all seasons through hotbed cultivation, so kimjang (Korean pickled kimchi for overwintering) was kept for a long time and consumed during the winter. ) Even if you don't pickle the kimchi,
It is available for consumption at all times. However, even if vegetables such as Chinese cabbage are supplied seasonally through hotbed cultivation, they must be fermented for a long time in the winter, and in the summer they become rancid and become sour within a short period of time. In many cases, kimchi is made into kimchi, and there is also a problem in storing kimchi that has been fermented in an appropriate state, as the unique odor of kimchi may affect other foods.

Furthermore, although kimchi production has been industrialized and kimchi is mass-produced, there are problems in the process of fermenting kimchi, in which the inside of the kimchi is not fermented to the optimum condition and only the surface is fermented. There were many difficulties in storing it under optimal conditions, as it could even go rancid.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fermentation refrigeration/warming device that can ferment fermented foods to an optimal state within a short time and store them in an optimal state.

FIG. 10 shows an operating state diagram of the gas sensing unit during kimchi fermentation, where GV is the fermentation and ripening reference voltage programmed in the microcomputer unit 2, and TL, TM % TN
is the discharge voltage of fermentation gas.

In explaining the present invention based on the above-described drawings and configuration, an example of kimchi fermentation will be described.

First, if you carefully consider the principle of kimchi fermentation, the main ingredient of kimchi is vegetables, and in kimchi fermentation, the cell fluid components of vegetables and seasoning components are mutually exchanged, and lactic acid fermentation is progressed by lactic acid bacteria. Lactic acid, organic acids, carbon dioxide gas, etc. are discharged.

In kimchi fermentation, the taste of kimchi is determined by the carbon dioxide gas and organic acids generated by lactic acid fermentation, and the conditions for this lactic acid fermentation to occur well include fermentation temperature, fermentation time, and additives. It will be determined by the seasoning etc.

Now pickle the kimchi and put it in the fermentation vat 108, place it on the shelf 107 inside the fermentation/refrigerating equipment configured as shown in Fig. 3, and press the kimchi fermentation key in the function selection section 1 to start the kimchi fermentation. A function signal is output to the microcomputer section 2. Then, the microcomputer unit 2 accesses the kimchi fermentation program and outputs kimchi fermentation display data to the function display unit 3 and function status data to the power outage function memory unit 13. At the same time, the microcomputer section 2 inputs the signals output by each sensor,
Selectively outputs a predetermined data signal to the compressor drive unit 4 and heater drive unit 5 according to the program procedure,
Pumping data is output to each pressure electromagnetic pump drive section 6.

At this time, the function display section 3 inputting the kimchi fermentation display signal output from the microcomputer section 2 displays the kimchi fermentation state, and also displays the inside temperature sensing section 7.
After the temperature inside the refrigerator is displayed numerically for a predetermined time, the open fermentation operation time for a predetermined time is displayed, and then the current time is displayed again.

On the other hand, the pressure electromagnetic pump drive unit 6 inputting the data output from the microcomputer unit 2 described above pumps the air inside the refrigerator through the air intake/exhaust pipe 116 connected to the pressure discharge pipe 114 as shown in FIG. The electromagnetic pump 120 is driven so that the air pressure inside the chamber can be compressed into the fermentation vat 108 through the pressure transmission pipe 112.

Therefore, the fermentation vat 108 within the insulated cabinet 102
The kimchi that is served inside the kimchi undergoes a rapid exchange of seasoning components and cell fluid components due to air pressure, and the inside of the kimchi is fermented at a constant temperature. Then, by pumping the electromagnetic pump 120, the pressure of the air in the chamber is continuously applied to the fermentation vat 108, and when the pressure becomes constant, the compressed air is discharged through the pressure discharge valve 115 configured as shown in FIG. The fermentation gas released in the air is detected by the gas sensor 117 and output to the gas sensing section 9.

That is, due to the pumping of the electromagnetic pump 120, the air in the chamber is compressed through the pressure transmission valve 109 of the fermentation vat 108 shown in FIG. 5, and when the pressure exceeds a certain level, it is discharged through the pressure discharge valve 115.

The pressure discharge valve 115 described above is as illustrated in FIG.
Case 124, holder guide 125, fixing hole 126,
M127, rubber backing 128, spring 129
and the holder body 130, so when the internal pressure of the fermentation vat 108 exceeds a certain level, the rubber backing 128 pushes the spring 129 and the holder body 13
It is discharged through the inner groove of 0.

At this time, the kimchi fermentation gas discharged from the fermentation vat 108 is transferred to the gas sensor 11 of the gas sensing section 9 as described above.
7 and is discharged into the refrigerator through the pressure discharge pipe 114 and the internal intake/exhaust pipe 116. Further, a fermentation temperature sensor 11 provided inside the fermentation vat 108
1 senses the temperature of the food, outputs the voltage of a predetermined sensing signal to the fermentation temperature sensing processing section 12 through the fermentation temperature sensing section 11, further converts it into a digital signal, and then outputs the voltage of a predetermined sensing signal to the microcomputer section 2.
Output to.

At this time, the microcomputer unit 2 programmatically sets the kimchi fermentation standard temperature HX°C as shown in FIG. The signal is converted by the section 7 into a signal of a predetermined internal temperature sensing voltage. This internal temperature sensing voltage is converted into a digital signal by the internal temperature sensing processing section 8, and this signal is read by the microcomputer section 2.

The microcomputer section 2, which has input the data outputted from the fermentation temperature sensing processing section 12 and the internal temperature sensing processing section 8, compares the two input data and determines whether the compressor drive section 4 or the heater drive section A drive signal is selectively outputted to 5.

At this time, if the fermentation sensing temperature sensed by the fermentation temperature sensor 111 is Hl, and the inside temperature sensed by the inside temperature sensor 106 is HY, then the fermentation sensing temperature H is shown in FIG. H as illustrated in
When l > Hx + X and Hy is Hv > Hx + 4 [at this time, X is the temperature constant ('C), which is the temperature constant that determines the control of the compressor or heater].

Therefore, the compressor drive unit 4 is driven, and the compressor (not shown) is driven as shown in F in FIG. 8, and cold air is generated from the cold air plate 104 in FIG. 3. Due to this cold air, the internal temperature H7 in the heat insulating cabinet 102 of the fermentation cold storage device shown in FIG. (Y is the temperature constant (°C) of the compressor heater-temperature control dip (D i P)).

Hx + X Y< Hy < Hx + X +
Y ・・・・・・(1) ■(U -X < H+
＜ HX + X ・・・・・・・・・・・・
(2) Therefore, when the internal temperature HY is lowered as shown in (112) above, the fermentation sensing temperature H8 of the fermentation vat 108 also operates as shown in (2) 2 above, and as shown in Fig. 7. As shown in C, the fermentation standard temperature is lowered to HX°C of the program built into the microcomputer section 2.

Therefore, the temperature Hv inside the refrigerator also decreases to the fermentation reference temperature Hx''c as shown in C shown in FIG.

On the other hand, due to the continuous operation of the compressor drive unit 4, cold air is continuously generated from the cold air plate 104, and the fermentation sensing temperature H, of the fermentation temperature sensor 111 inside the fermentation vat 108 reaches the fourth level. As shown in Figure 7 E, Hl
< HX - The sensing processing section 12 and the internal temperature sensing processing section 8 convert the signals based on the above-mentioned respective temperatures into digital data and input the digital data to the microcomputer section 2 .

At this time, the fermentation temperature sensing processing section 12 and the chamber temperature sensing processing section 8
The microcomputer unit 2 inputs the data outputted from the kimchi fermentation program, and compares the data inputted from the two sensing units 8 and 12 to maintain and output the fermentation reference temperature Hx'c of the kimchi fermentation program, and determines the internal temperature. When it is determined that the temperature is low, data is output to the heater drive unit 5 to drive the heater (not shown) as indicated by G in FIG.

Therefore, hot air is generated from the heater heat dissipation plate 105 shown in FIG. Works like Eq.

HX −X−Y<Hv<)(X−x+y ・−・・
−・(3) Hx X < Hl < HX + X
・・・・・・・・・・・・(4) Therefore, the temperature inside the refrigerator HY increases as shown in the equation (3) above, so the temperature shown as H in Figure 9 As a result, the fermentation sensing temperature H1 of the fermentation vat 108 is operated as shown in equation (4) above, and as shown in C in FIG. be raised.

By the method described above, the microcomputer section 2 controls the temperature H7 in the refrigerator by inputting the temperature sensing processing signal detected by the fermentation temperature sensor 111 and the refrigerator temperature sensor 106 and converted and output as a digital signal. Accordingly, the fermentation temperature sensor 1 of the fermentation vat 108
The fermentation sensing temperature H, according to No. 11 is as shown in (5) 2 below, and the microcomputer unit 2 can maintain the fermentation temperature of the kimchi fermentation program.

HX X< Hl < HX + X...
・Old...(5) Therefore, the internal temperature HV is Hx
When X<Hy<HV+X, the microcomputer unit 2 determines that the temperature is the most suitable for kimchi fermentation and does not output data to the compressor drive unit 4 and heater drive unit 5. Conversely, when the fermentation sensing temperature H1 is out of the range of HX±X, the microcomputer section 2 inputs the chamber temperature Hv sensed by the chamber temperature sensor 106 and determines that the fermentation reference temperature HX is outside the range. Thereafter, as described above, predetermined data is selectively outputted to the compressor drive section 4 or the heater drive section 5, and the compressor and heater are set to the kimchi fermentation temperature according to the kimchi fermentation program built in the microcomputer section 2. to drive the internal temperature H
Adjust 7.

On the other hand, the temperature inside the chamber H is adjusted as described above, and the fermentation vat 1
The fermentation sensing temperature H1 of 08 is the kimchi fermentation standard temperature Hx'c
As described above, the pressure of the air inside the warehouse is continuously applied to the fermentation tub 108 by the operation of the electromagnetic pump 120 as described above, and when the kimchi in the fermentation tub 108 ferments, gas is generated.

When the gas generated by fermentation reaches a certain amount, it is discharged through a pressure discharge valve 115 as shown in A in FIG. 10, and the discharged fermentation gas is detected by a gas sensor 117.

At this time, the voltage of the gas sensor 117 that senses the fermentation gas is varied depending on the amount of gas released from the fermentation vat 108. When the fermentation of the kimchi in the fermentation vat 108 reaches a ripening state, the amount of gas released increases, and the voltage T of the gas sensor 117 that senses this increases to the fermentation and ripening reference voltage (G V) as shown in B in Fig. 10. When this point is reached, the microcomputer section 2 determines that the kimchi fermentation is complete. That is, when the voltage of the gas sensor 117 that senses the fermentation gas is input to the gas sensing processing section 10, converted into a digital signal, and then input to the microcomputer section 2, the microcomputer section 2 reads the input data, After determining whether it is the programmed fermentation and ripening reference voltage (GV), if it is the fermentation and ripening reference voltage (GV), it is determined that the fermentation is completed, and the data is output to the heater drive unit 5, and the fermentation vat 108 In order to prevent the kimchi inside from spoiling, the fermented kimchi is heated at a high temperature (60° C. to 65° C.) and subjected to photothermal treatment.

If the amount of gas released from inside the fermentation vat 108 does not reach the fermentation and ripening reference voltage (GV) even after a certain period of time has elapsed, as shown in TL or T of B in Figure 1O, the programmed When the maximum kimchi fermentation time FH has elapsed, fermentation is automatically terminated to prevent kimchi from ripening prematurely. That is, after the maximum kimchi fermentation time FH is calculated using an internal timer and continues for several tens of minutes, the data signal output to the heater drive unit 5 is interrupted, and the data is output to the compressor drive unit 4 to adjust the temperature inside the refrigerator. The rapidly cooled and fermented kimchi is stored at -3°C to +3°C.

Therefore, the kimchi fermented by the above-mentioned method has a pH of around 4.3 and is kept in the optimum state for a long period of time to give the best taste of kimchi.

On the other hand, when a function key such as bread fermentation or amazake fermentation is selected from the function selection section 1, the microcomputer section 2 inputs the key status signal, analyzes it, and then executes the corresponding program. (gas sensing operation is stopped at this time), bread fermentation temperature (HQ), bread fermentation time (T
Q) is controlled to the optimum state, fermentation temperature (HR) of amazake,
It has a built-in program that can control the fermentation time (TR) of amazake to an optimal state, and a built-in program that can set the maximum fermentation time to prevent premature ripening.

On the other hand, the functions of the refrigerator and freezer are such that the standard temperature of the existing refrigerator is set, and the microcomputer unit 2 determines the temperature based on the detection signal from the internal temperature sensor 106 and controls the compressor 4. When the function of the rice bucket is inputted from the function key selection unit 1 to select the corresponding function, the internal temperature is detected by the internal temperature sensor 106, and then the internal temperature is detected by the internal temperature sensor 106. ! 4
! The heater drive unit 5 is controlled by a temperature program.

The clock function was programmed to always display the time using a timer installed inside the microcomputer section 2.

As described above, the present invention automatically ferments fermented foods such as kimchi, breads, and amazake to the optimum fermentation state, and stores them under refrigeration in the optimum state so that they can be preserved for a long time. As households become nuclear families, it is now possible to pickle an appropriate amount of kimchi and store it in optimal conditions for a long period of time, and since it is equipped with a refrigerating and heating function, it can be used in a variety of ways, even if necessary. It can be used for various functions, and even when kimchi is mass produced, it can be fermented to the optimum condition and then stored in a refrigerator, which is a great advantage for the industrialization of kimchi.
