진공포장봉지의 살균장치{APPARATUS FOR STERILIZING VACUUM PACK}Sterilizer for vacuum packaging bag {APPARATUS FOR STERILIZING VACUUM PACK}

본 발명은 진공포장봉지의 살균장치에 관한 것으로, 더욱 상세하게는 진공상태에서 식품을 포장한 합성수지재의 봉지를 살균하는 과정에서 봉지내의 식품이 변질되지 않도록 살균하는 진공포장봉지의 살균장치에 관한 것이다.The present invention relates to a sterilization apparatus for a vacuum packaging bag, and more particularly, to a sterilization apparatus for a vacuum packaging bag for sterilizing the food in the bag in the process of sterilizing the bag of synthetic resin packaging the food in a vacuum state. .

일반적으로, 가공된 식품은 진공상태에서 비닐과 같은 합성수지재의 봉지에 담아 포장함으로써 최종 소비자가 소비할 때까지 변질되지 않고 최초의 맛을 유지시키게 된다.In general, the processed food is packaged in a bag of synthetic resin such as vinyl in a vacuum to maintain the original taste without altering until the end consumer consumes.

이때, 가공된 식품을 진공상태로 포장한 봉지는 반드시 살균과정을 거쳐 식품의 변질없이 장기 보존이 가능하도록 하고 있다.At this time, the bag in which the processed food is packed in a vacuum state must be sterilized to allow long-term storage without deterioration of the food.

여기서, 종래의 살균방법에는 온탕살균방법과 증기살균방법이 있는데, 이 온탕살균방법은 100℃미만의 저온에서 살균을 실시하기 때문에 효과적인 살균이 이루어지지 않게 되고, 증기살균방법은 100℃이상의 고온에서 살균이 이루어지기 때문에 효과적인 살균을 실시할 수 있다.Here, the conventional sterilization method is a hot water sterilization method and steam sterilization method, this hot water sterilization method is sterilized at a low temperature of less than 100 ℃ effective sterilization is not achieved, steam sterilization method at a high temperature of more than 100 ℃ Since sterilization takes place, effective sterilization can be performed.

이러한 증기살균방법을 채택하고 있는 종래의 살균장치는 가공된 식품을 진공상태로 포장한 봉지를 밀폐된 쳄버내에 넣고, 증기로 가압하는 동시에 가열하여 살균하게 된다.Conventional sterilization apparatus employing such a steam sterilization method is to put the processed food in a sealed bag in a vacuum chamber, pressurized with steam and heated to sterilize.

그리고, 살균의 적정시간이 경과되어 쳄버를 개방하게 되면 쳄버내의 증기가 대기로 방출되면서 쳄버내의 온도와 압력이 급속히 떨어지게 되고, 진공포장봉지는 대기에 노출된 상태에서 내부의 식품이 증발되면서 증기압에 의해 팽창된다.When the chamber is opened after the proper time of sterilization, the steam in the chamber is discharged to the atmosphere, and the temperature and pressure in the chamber are rapidly dropped. By swelling.

이때, 진공포장봉지가 살균과정을 거친 후에도 냉각되지 못하고 증기압에 의해 팽창된 상태를 유지하게 되면 그 내부의 식품이 변질되는 문제가 있다.따라서, 이러한 문제를 개선하기 위하여 진공포장봉지를 쳄버내에서 고온고압의 증기를 이용하여 살균한 후, 바로 쳄버를 개방하지 않고 냉각수를 냉각라인으로 공급하여 쳄버내의 온도를 낮추게 되고, 이때 쳄버내의 온도와 압력이 동시에 저하되면서 가열상태의 진공포장봉지를 냉각시키게 된다.그러나, 쳄버내의 냉각속도에 비해 진공포장봉지내의 온도는 서서히 냉각되고, 쳄버내의 압력이 저하되면서 아직 고온상태를 유지하고 있는 봉지내 식품의 수분이 증발되어 장시간 증기압에 의해 팽창되는 문제가 여전히 발생된다.At this time, if the vacuum packaging bag is not cooled even after sterilization process and is kept inflated by vapor pressure, there is a problem that the food inside thereof is deteriorated. Therefore, in order to improve such a problem, the vacuum packaging bag is After sterilization using high-temperature, high-pressure steam, the cooling water is supplied to the cooling line without opening the chamber immediately to lower the temperature in the chamber. At this time, the temperature and pressure in the chamber are simultaneously reduced to cool the vacuum packaging bags under heating. However, compared to the cooling rate in the chamber, the temperature in the vacuum packaging bag is gradually cooled, and as the pressure in the chamber decreases, the water in the bag, which is still at a high temperature, evaporates and the water is still expanded. Is generated.

본 발명은 진공상태에서 식품을 포장한 합성수지재의 봉지를 고온고압의 증기를 이용하여 살균한 후, 다시 고압하에서 냉각함으로써 봉지내의 식품이 증발되는 현상을 방지하고, 이로써 봉지내의 식품이 변질되지 않도록 살균하는 진공포장 봉지의 살균장치를 제공함에 그 목적이 있다.The present invention sterilizes a bag of a synthetic resin packaging the food in a vacuum state using a high temperature and high pressure steam, and then cooled again under high pressure to prevent the food in the bag to evaporate, thereby sterilizing the food in the bag so as not to deteriorate. The purpose of the present invention is to provide a sterilization apparatus for vacuum packaging bags.

상기한 목적을 달성하기 위하여 본 발명은 밀폐된 쳄버의 선반위에 놓여진 진공포장봉지를 설정된 살균온도 및 시간동안 살균증기공급부에서 공급되는 고온고압의 증기로 살균하는 진공포장봉지의 살균장치에 있어서, 압력공기주입밸브를 통해 압력공기를 주입하여 살균시보다 높은 고압상태를 유지하면서 냉각수주입밸브를 통해 펌핑되는 냉각수를 냉각수살수기로 살수하여 살균된 진공포장봉지를 냉각하며, 수위검출기의 감지신호에 따라 냉각수배출밸브를 통해 배수하도록 구성하되, 살균된 진공포장봉지의 냉각시 냉각수의 증가로 상기 쳄버내에 초과압력이 발생되면 배기조절기에 의해 흡배기밸브가 개방되도록 구성하는 것을 특징으로 하는 진공포장봉지의 살균장치를 제공하게 된다.In order to achieve the above object, the present invention provides a sterilization apparatus for a vacuum packaging bag sterilized by a high temperature and high pressure steam supplied from a sterilization steam supply for a predetermined sterilization temperature and time placed on a vacuum packaging bag placed on a closed chamber. By injecting pressure air through the air inlet valve, it maintains a higher pressure than sterilization while sprinkling the coolant pumped through the coolant inlet valve with a coolant sprayer to cool the sterilized vacuum packaging bag, and according to the detection signal of the water level detector It is configured to drain through the discharge valve, the sterilization apparatus of the vacuum packaging bag, characterized in that configured to open the intake and exhaust valve by the exhaust regulator when the excess pressure occurs in the chamber due to the increase in the cooling water during the cooling of the sterilized vacuum packaging bag Will be provided.

도면을 참조하여 본 발명을 상세히 설명하기로 한다.The present invention will be described in detail with reference to the drawings.

도1은 본 발명에 따른 진공포장봉지의 살균장치의 일실시예를 나타내는 구성도이고, 도2는 본 발명에 따른 진공포장봉지의 살균장치의 다른 실시예를 나타내는 구성도이며, 도3은 본 발명에 따른 진공포장봉지의 살균장치의 또다른 실시예를 나타내는 구성도이다.Figure 1 is a block diagram showing an embodiment of the sterilization apparatus of the vacuum packaging bag according to the present invention, Figure 2 is a block diagram showing another embodiment of the sterilization apparatus of the vacuum packaging bag according to the present invention, Figure 3 It is a block diagram which shows another Example of the sterilization apparatus of the vacuum packaging bag which concerns on this invention.

본 발명에 따른 진공포장봉지의 살균장치는 쳄버(1)의 선반(19)에 놓여진 진공포장봉지를 살균증기공급부를 통해 공급되는 고온의 증기를 이용하여 고압하에서 살균한 후, 다시 고압하에서 냉각시킴으로써 진공포장봉지내의 식품이 증발되는 현상을 방지하도록 구성되어 있다.Sterilizing apparatus for a vacuum packaging bag according to the present invention by sterilizing the vacuum packaging bag placed on the shelf 19 of the chamber (1) using high temperature steam supplied through the sterilization steam supply unit, and then cooled again under high pressure It is configured to prevent the food from being evaporated in the vacuum packaging bag.

다시 말하면, 살균하고자 하는 진공포장봉지를 쳄버(1)내에 설치된 다층의 선반(19)위에 올려 놓고 쳄버를 밀폐시킨 후, 살균온도 및 살균시간을 설정하고 작동시키게 된다.이때, 쳄버(1)내에 고온고압의 증기를 공급하는 살균증기공급부는 도1에 도시한 바와 같이 증기주입밸브(28)를 개방하여 증기투입구(27)를 통해 고온고압의 증기를 쳄버(1)내에 직접 공급하거나, 도2에 도시한 바와같이 전기히터스위치(41)를 온(on)상태로 동작시켜 쳄버내의 바닥에 설치된 전열배관(33)에 전원을 공급하게 되면 쳄버내의 물이 가열되면서 증기를 발생시키는 구조이다.또는, 살균증기공급부는 도3에 도시한 바와 같이 열매체공급밸브(42)를 개방하게 되면 쳄버(1)내의 바닥에 설치된 열매체배관(34)에 열매체가 공급되면서 쳄버내의 물을 가열시켜 증기를 발생시키게 된다.이처럼, 살균증기공급부에서 공급되는 증기에 의해 쳄버(1)내의 온도와 압력이 설정된 온도 및 압력까지 증가되면서 선반(19)상의 진공포장봉지가 살균되고, 설정된 살균시간이 경과되면 증기공급부에 의한 증기공급이 중단된다.즉, 설정된 살균시간이 경과되면 증기주입밸브(28)가 닫히어 증기공급을 차단하거나 전기히터스위치(41)가 오프(off)상태로 동작되면서 전열배관(33)의 전원 공급을 끊거나, 또는 열매체공급밸브(42)가 닫히면서 열매체배관(34)으로의 열매체공급을 차단하여 쳄버(1)내로 더이상의 증기공급을 중단시키게 된다.그리고, 압력공기주입밸브(30)가 개방되면서 쳄버(1)내에 고압의 공기가 공급되고, 압력조절기(7)에는 쳄버(1)의 살균시 내압보다 약간 높게 압력이 설정되어 있다.이때, 압력공기주입밸브(30)의 개방과 함께 냉각수주입밸브(9)가 개방되고, 냉각수주입펌프(10)가 작동되면서 냉각수가 쳄버(1)내로 공급되고, 다시 냉각수살수기(11)를 통해 분사된다.여기서, 냉각수살수기(11)를 통해 분사되는 냉각수는 쳄버(1)내의 온도를 급격히 냉각시키게 되고, 쳄버내의 압력은 압력공기의 주입으로 진공포장봉지의 살균시 압력보다 약간 높게 유지된다.따라서, 살균과정을 거친 진공포장봉지는 살균시보다 높은 압력하에서 냉각수에 의해 급격히 냉각되기 때문에 봉지내 식품의 수분증발이 억제되고, 이러한 증발억제상태에서 식품의 냉각이 충분히 이루어지면 더이상 식품의 수분증발여지가 제거된다.이때, 진공포장봉지는 쳄버(1)의 고압하에서 냉각수에 의해 급격히 냉각되고, 봉지의 부풀임을 유발하는 식품의 증발현상이 일어나지 않게 되어 식품이 변질되는 문제는 발생되지 않게 된다.그리고, 냉각수살수기(11)를 통한 냉각수의 살수로 인해 쳄버(1)내의 수위가 증대되면서 쳄버내의 공기압이 계속적으로 커지게 되고, 이로 인해 이상압력이 발생되면 이를 배기조절기(29)에서 감지하게 되고, 이때 흡배기밸브(4)가 개방되면서 쳄버내의 압력공기를 외부로 배출하게 되어 쳄버내의 이상압력을 해소하게 된다.또한, 쳄버(1)내의 수위가 일정수준에 이르면 이를 만수수위검출기(18)에서 검출하게 되고, 이에 따라 냉각수주입펌프(10)가 정지되면서 냉각수주입밸브(9)가 닫히게 되며, 흡배기밸브(4)가 개방되면서 냉각수배출밸브(15)를 개방시키게 된다.이때, 냉각수배출펌프(16)를 작동시키게 되면 쳄버(1)내의 물이 외부로 배출되고, 배수수위검출기(17)가 쳄버내의 수위를 감지하게 되면 냉각수배출밸브(15)를 닫으면서 냉각수배출펌프의 작동을 정지시켜 더이상의 배수를 차단하게 된다.여기서, 쳄버(1)의 배수가 완료되면 살균작업의 종료를 알리는 부저가 울리게 되고, 쳄버로부터 진공포장봉지를 취외하면 모든 살균작업이 완료된다.In other words, the vacuum packaging bag to be sterilized is placed on the multi-layer shelf 19 installed in the chamber 1, the chamber is sealed, and then the sterilization temperature and sterilization time are set and operated. The sterilizing steam supply unit for supplying the high temperature and high pressure steam opens the steam injection valve 28 and directly supplies the high temperature and high pressure steam to the chamber 1 through the steam inlet 27, as shown in FIG. As shown in the drawing, when the electric heater switch 41 is operated in an on state to supply power to the heat transfer pipe 33 installed at the bottom of the chamber, the water in the chamber is heated to generate steam. The sterilization vapor supply unit opens the heat medium supply valve 42 as shown in FIG. 3 to heat the water in the chamber while generating heat by supplying the heat medium to the heat medium pipe 34 installed at the bottom of the chamber 1 to generate steam. do. As such, the vacuum packaging bag on the shelf 19 is sterilized as the temperature and pressure in the chamber 1 are increased to the set temperature and pressure by the steam supplied from the sterilizing steam supply unit. In other words, when the sterilization time is set, the steam injection valve 28 is closed to shut off the steam supply or the electric heater switch 41 is operated in an off state to supply power to the heat transfer pipe 33. Or stops supply of steam to the chamber 1 by stopping the heat medium supply to the heat medium pipe 34 while closing the heat medium supply valve 42. Then, the pressure air injection valve 30 High pressure air is supplied to the chamber 1 while being opened, and a pressure is set to the pressure regulator 7 slightly higher than the internal pressure at the time of sterilization of the chamber 1. At this time, with the opening of the pressure air injection valve 30, Coolant Injection Valve (9) When the cooling water injection pump 10 is opened, the cooling water is supplied into the chamber 1, and is then injected through the cooling water sprayer 11. Here, the cooling water injected through the cooling water sprayer 11 is chamber 1 The temperature in the chamber is rapidly cooled, and the pressure in the chamber is kept slightly higher than the pressure during the sterilization of the vacuum packaging bag by the injection of pressure air. Since the water is cooled, water evaporation of the food in the bag is suppressed, and if the food is sufficiently cooled in such an evaporation suppression state, the water vapor evaporation is no longer removed. At this time, the vacuum packaging bag is applied to the cooling water under the high pressure of the chamber 1. As a result, the food is rapidly cooled and the evaporation phenomenon of the food causing the swelling of the bag does not occur, thereby preventing the food from being deteriorated. As the water level in the chamber 1 increases due to the sprinkling of the cooling water through the cooling water sprayer 11, the air pressure in the chamber is continuously increased, and when the abnormal pressure is generated, it is detected by the exhaust regulator 29. At this time, the intake / exhaust valve 4 is opened to discharge the pressure air in the chamber to the outside to solve the abnormal pressure in the chamber. In addition, when the water level in the chamber 1 reaches a predetermined level, the water level detector 18 When the cooling water injection pump 10 is stopped, the cooling water injection valve 9 is closed, and the intake / exhaust valve 4 is opened to open the cooling water discharge valve 15. At this time, the cooling water discharge pump ( When 16) is activated, the water in the chamber 1 is discharged to the outside, and when the water level detector 17 detects the water level in the chamber, the cooling water discharge pump 15 is closed and the operation of the coolant discharge pump is stopped. It is to block the drainage of any more. Here, when a multiple of the chamber (1) complete and ring the buzzer to inform the end of the sterilizing operation, when chwioe the vacuum packaging pouch from the chamber any sterilization operation is complete.

본 발명은 진공상태에서 식품을 포장한 합성수지재의 봉지를 고온고압의 증기를 이용하여 살균한 후, 다시 고압하에서 냉각함으로써 봉지내의 식품이 증발되는 현상을 방지하고, 이로써 봉지내의 식품이 변질되지 않도록 살균할 수 있고, 살균시간을 줄일 수 있을 뿐만 아니라 살균효과를 증대시킬 수 있는 효과를 제공하게 된다.The present invention sterilizes a bag of a synthetic resin packaging the food in a vacuum state using a high temperature and high pressure steam, and then cooled again under high pressure to prevent the food in the bag to evaporate, thereby sterilizing the food in the bag so as not to deteriorate.
