Description

Kimchi Refrigerator and Fermentation storing equipment}

The present invention relates to a maturation control system and apparatus of a kimchi refrigerator, and more particularly, to determine the degree of fermentation of kimchi in a closed container for kimchi storage, the pressure in the container is composed of a displacement piezoelectric sensor or a potential difference sensor (LVDT). 6) Automatically detects and automatically controls the fermentation temperature, which is an important factor of Kimchi fermentation and fermentation process, to minimize the over ripening and immaturity of Kimchi under Kimchi ripening conditions, and to let Kimchi smell into Kimchi refrigerator It is to prevent contamination by other foods stored together by preventing them from being.

In general, kimchi is a natural fermented food unique to Korea, and the rate of fermentation and decay of kimchi varies with temperature. In other words, kimchi is fast fermentation and decay progression at high temperature is fast ripening, when the temperature is low fermentation and decay progression is slow. In particular, the taste of kimchi greatly depends on the ripening state of kimchi, but the ripening period is shorter at high temperature, but the kimchi taste is lower than the low temperature ripening, and the taste is good at low temperature, but the ripening period is too long. In addition, the fermentation and decay rate of kimchi varies depending on the salinity of kimchi. Therefore, when the salinity of kimchi is low, the fermentation and decay is slow. There is.

The kimchi aging control pattern of the conventional kimchi refrigerator disclosed in patent publication 98-129226 is the first step of setting the aging temperature and time according to the required degree of aging and performing the first aging process with the set value, and the smell of kimchi In order to remove, the second step of dropping the temperature set in the first step to a predetermined temperature and then maintained for a predetermined time, and in order to give a unique kimchi taste, the temperature is changed irregularly within a predetermined temperature range The third step is to keep the kimchi while making it,

Kimchi refrigerator kimchi ripening control pattern showing another example of the prior art disclosed in the patent publication 96-11625 sets the time of the first ripening step for each ripening mode, and measure the salinity of kimchi before the first ripening step according to the salinity The first ripening step of resetting the ripening time of the first ripening process by adding or subtracting a certain time to the set time and ripening at a constant temperature (T1) for the reset ripening time (t1), and the second by each ripening mode. Set the ripening time and reset the set time according to the measured salinity of kimchi and the second ripening step of ripening at a constant temperature (T2) for the reset time (t2), and the time of the third ripening process for each ripening mode After setting the and according to the measured salinity of the kimchi to reset the set time to lower the storage mode temperature (T3) for the reset time (t3) and the step of storing at the storage mode temperature (T3) Made up All.

Figure 3 shows the sealed container 7 is inserted into the kimchi refrigerator,

A container 7 for storing kimchi; A container lid 9 coupled to an upper portion of the container 7 and having one side portion recessed inward; The container stopper 10 (internally-opened application No. 20-2002-0027411, which is fastened to the recessed position of the container lid 9, having a displacement bar 13 indicating an internal pressure formed inside the center) Stopper)

The displacement difference bar 13 is formed of a permanent magnet to be detected by the displacement difference detection sensor 6 formed by the potential difference sensor LVDT.

4 is formed inside the center of the container stopper 10 formed on the container lid 9, according to the change in the internal pressure of the closed container 7 (pressure change inside the container according to the carbon dioxide generated during fermentation of kimchi) A displacement difference detection sensor 6 formed of a conventional piezoelectric sensor or a potential difference sensor LVDT is placed on an upper portion of the displacement difference bar 13 that moves up and down, and the displacement difference of the displacement difference bar 13 is measured and measured. It is shown that the value is transmitted to the central control unit 3 in real time.

In more detail, the operation of the system to control the kimchi ripening state,

When the kimchi is not placed in the container, the pressure detected by the container stopper 10 and the displacement difference sensor 6 located in the opened kimchi container lid 9 and the temperature detected by the temperature sensor 5 are Kimchi. It is transmitted to the central control unit 3 of the refrigerator.

At this time, the central Kimchi refrigerator control unit 3 transmits the temperature control command set by the control unit 1 to the temperature controller 4 for initial setting of the Kimchi refrigerator and initializes the process state (initialization) on the LCD display. ) And temperature and pressure.

Put the kimchi in a vacuum container or a container 7 to maintain the pressure, the vacuum pump or the container lid inside the sealed container 7 so that a constant vacuum can be formed through the container stopper 10 to maintain the vacuum, pressure Form a vacuum using the method of shrinking. At this time, the displacement bar 13 is sucked into the container under the influence of the vacuum, the displacement difference detection sensor 6 measures the degree of vacuum and transfers it to the central control unit (3).

Kimchi refrigerator central control unit (3) detects the vacuum and temperature through the displacement difference sensor (6) and the temperature sensor (5), and is fixed to the temperature control device (4) according to the command transmitted from the control operation unit (1) Maintain fermentation temperature. In addition, the process state (during fermentation) of the kimchi refrigerator, the temperature and the pressure in the closed kimchi container are displayed on the status display unit 2.

In the kimchi refrigerator that maintains the fermentation temperature, when the kimchi is fermented, lactic acid and carbon dioxide are discharged. As the fermentation proceeds, the carbon dioxide raises the pressure in the closed kimchi container.

The pressure in the closed hermetically sealed kimchi container is sensed by the displacement differential sensor 6 and transmitted to the central control unit 3 together with the temperature detected by the temperature sensor 5, in the sealed container 7 for kimchi storage. When the pressure reaches the predetermined fermentation completion pressure, the central controller 3 sends a signal to the temperature controller 4 to maintain the temperature of the kimchi refrigerator at the temperature determined in the ripening step of the kimchi.

The temperature detected by the temperature sensor 5 and the displacement differential sensor 6 and the pressure and process state (during maturation) in the kimchi container are displayed on the status display part 2.

When the kimchi refrigerator reaches a aging temperature set lower than the fermentation temperature, the pressure in the initial closed container 7 becomes lower than the pressure at the completion of fermentation due to the contraction of the gas in the closed kimchi container according to Boyle-Charles' law. .

However, even during kimchi ripening, the carbon dioxide generated during the ripening of kimchi re-raise the pressure in the kimchi container, and when the predetermined maturation completion pressure is reached, the displacement differential sensor 6 may not display the pressure information in the closed container 7. The temperature sensor 5 transmits the sensed temperature to the central controller 3 of the kimchi refrigerator, and the central controller maintains the temperature of the kimchi refrigerator at the storage temperature through the temperature controller 4.

When the aging process of kimchi is finished according to the above process (measured by measuring the pressure in the airtight container 7 through the displacement sensor 6), maintaining the unique taste of the kimchi matured by the central controller 3 To control the temperature control device (4) to maintain a certain temperature so that the kimchi is no longer aged and kept,

The temperature sensed by the temperature sensor 5 and the displacement differential sensor 6 and the pressure in the kimchi container and the process state (during storage) are displayed on the status display unit 2.

During the storage of kimchi, even after the kimchi container is opened and the kimchi is taken out and the vacuum is kept in the sealed container 7 at a lower than 1 atmosphere, the effect of the second fermentation and the effect of decomposing by residual oxygen in the kimchi container As a result, when the pressure in the vacuum pressure sealed container rises, the displacement differential sensor 6 causes it to display the pressure on the status display unit 2 through the central control unit 3 of the kimchi refrigerator.

When the pressure in the kimchi container reaches a given range, the status display unit 2 sends a voice or flashing signal to the user, so that the user can release the pressure in the kimchi container.

At this time, the user discharges the carbon dioxide inside at least through the container cap 10 installed in the container lid 9 to preserve the taste and aroma of kimchi.
