Description

An air aging system at a ripening room that is aged at an ice temperature. {Air aging system at a ripening temperature.}

The present invention relates to an air aging device for aging the stored material in the aging cell at ice temperature. The present invention relates to an air aging device capable of being suppressed and capable of being stored/aged for a long period of time and having improved taste and flavor.

In general, aging refers to the phenomenon of slowly decomposing muscle fibers by enzymes naturally occurring inside meat.

In particular, it weakens the connective tissue of actic and myosin produced during post-mortem stiffness, softening the meat and improving the taste, as well as decomposing nucleic acids such as ATP and polishing ingredients such as IMP to give off a unique flavor.

And there are dry aging methods and wet aging methods as these aging methods,

In particular, the dry aging method is called dry aging, and has been continuously used from the past to the present. That is, for a period of at least 10-40 days, it is ventilated in a low temperature state (1 ~ 3℃) to be aged. At this time, the stored material has the characteristic of giving off a unique fragrance when dry-aged, but as the surface is exposed to the outside air, the surface becomes hard and rotten. There was a problem in that the loss rate was increased by spreading throughout the water.

In addition, wet aging is referred to as wet aging or water aging, and is a method of aging the stored material in a vacuum-packed state in a water tank at a low temperature. At this time, the stored material is aged in a vacuum-packed state, and there is little loss of meat, and it has the advantage that it can be aged easily by controlling the temperature of the water.

And recently, an ice-temperature aging method has been developed in which the temperature from the surface to the center of the storage is cooled to below 0°C and then aged.

This is because the freezing point of water is 0℃, but the moisture contained in the stored goods such as pork or beef is not pure water, so it has to be cooled down to -1.7℃ or less on average on average. It is a method of aging in the corresponding section by calling it the ice temperature section.

And as the cells mature in the ice temperature section, as the cells approach the freezing point, starch and protein are decomposed to produce sugar and amino acids. there is an advantage.

However, when aging on ice, it is necessary to control the surface and core of the stored material so that it does not freeze in the temperature range of 0°C to -1.7°C.

If the stored water drops below -2℃ and the cells freeze, the water molecules in the storage become larger when they are in the solid state than when they are in the liquid state, and the ice molecules damage the tissues of the storage.

There was a disadvantage that the flesh escaped through the gaps in the damaged tissue during thawing.

By configuring the discharge plate to make the inner space into an electric field filled with electric charges by the controller, the electric charge continuously stimulates the water molecules of each store to vibrate, allowing the stored items that are not completely cooled to age at ice temperature in the inner space.

Therefore, in the present invention, when the stored material is aged by circulating cold air, the water molecules of the stored material are continuously polarized/vibrated by the electric charge forming the electric field, and the ice temperature section is expanded to -5°C to stably age the stored material at ice temperature. became possible

In addition, the present invention prevents the loss (weight loss) of the stored material during aging because the surface is not corroded while the water molecules are continuously polarized/vibrated by electric charge even if the stored material is not vacuum-packed, while bacterial propagation is suppressed to preserve and mature period could be extended. In other words. It is economically advantageous because there are no packaging costs due to vacuum packaging and loss costs due to surface removal (reduction) of stored objects due to spoilage.

At this time, the controller 30 is a cooling means, a recycling means to form an optimal aging space without forming frost in the inner space by the opening and closing of the door. It is also possible to control the operation by connecting the drying means, etc.

And the controller 30 is a control panel 37 having a button on one end of the case for controlling the type of storage or the amount of emitted charge, and a button for controlling the temperature, humidity, and time of the inner space. to form,

On the inside, a microcomputer 31 that controls to apply a high voltage to the discharge plate according to the type of storage set through the control panel 37, and a primary coil and a secondary coil are magnetically coupled to boost commercial power to a high voltage to increase the voltage of the discharge plate.

The discharge plate is configured to radiate charge only when the plate is stationary and closed.

In addition, according to the embodiment, a timer 38 is provided to determine the intensity of the voltage applied to the discharge plate 60 by the discharge unit according to the closing time of the door (eg, the time during which the electric field is formed in a closed state). It can also be configured to change step by step.

That is, the discharge unit 33 is configured to initially apply a high voltage to make the inner space an electric field, and then emit charges only when the door is closed. In response to the instruction of the microcomputer 31, the intensity of the voltage applied to the discharge plate 60 is gradually increased (eg, 9 steps if 10 minutes pass, 8 steps if 40 minutes pass, 7 steps if 80 minutes pass, etc.) By lowering the operating cost (eg electricity cost), it can be operated safely while at the same time.

On the other hand, the electric charge radiated by the inner part spreads wide to the left and right to have directivity.

Therefore, the present invention removes the outer skin of the stored material as it is stably aged at ice temperature in a state that does not decay while the water molecules of each stored product vibrate by the electric charge forming the electric field when the stored material is frozen at 0 degrees or less by circulating cold air. It does not need to be reduced (weight loss), and at the same time, cell proliferation is suppressed, so it can be stored and aged for a long time, and its taste and flavor are improved.
