Technical Field

The present invention relates to a rapid freezing apparatus for food, and more particularly, to a rapid freezing apparatus for food, which can rapidly freeze a lot of food in a short time by securing a sufficient portion of rapid freezing of food, and which is excellent in freezing efficiency, simple in structure, and easy to maintain. It relates to a quick freezing device for food.

Background

In recent years, the consumption of processed foods such as pork chops, dumplings and hamburgers and dough products such as fish foods and fish pastes has been rapidly increasing. In this regard, freezing techniques for freezing food products have been variously developed through many studies, for example, a nitrogen injection freezing method (rigid freezing) for quick freezing such as pork chop.

Such a nitrogen injection type refrigeration method has been proposed, for example, in patent No. 0165176 (hereinafter referred to as "reference 1"), patent nos. 10 to 0942034 (hereinafter referred to as "reference 2").

Reference 1 relates to a frozen food rapid cooling apparatus in which a pair of conveyors operated by a control device and a pair of conveyors are arranged in parallel with each other, wherein one side of the third conveyor is an inlet and an outlet of a main body. One end of the third conveyor is connected to the fourth conveyor while being installed to be exposed to the outside, and the driving means includes a driving motor for rotating the pair of stacked conveyors and extending to the driving motor for the first time. It is installed at one end of the coaxial and first rotating shaft and is composed of a first roller installed to be in close contact with the third conveyor. However, such a structure is complicated by the structure of the entire rapid cooling apparatus because a plurality of conveyors are organically stacked and connected in parallel to rapidly freeze frozen foods continuously moving on the plurality of conveyors. This may be advantageous in terms of space utilization of the refrigeration apparatus, but if the conveyor structure is complicated and any one or more of the plurality of conveyors malfunctions, the location of the malfunction is not easily identified and it takes a long time to repair because there is a problem with the disassembly of the interlocking conveyors for maintenance.

On the other hand, reference 2 relates to a tunnel freezing method of a multilayer structure for quick freezing of food and a refrigerant used therein, and a quick freezing apparatus of a freezer for freezing meat or fish provided as food for human consumption. In a tunnel-type rapid cooling device having a cooling device and a refrigerant exchange device, the cooling device is divided into a pre-cooling section, a rigid section and a submerged section, in which the food to be treated is operated without being immersed in the refrigerant liquid. This section is intended to operate in submerged condition, in a pre-cooling section, in which pre-cooling of cold air in the range-40 ± 5 ℃ is generated by using a freezer separately installed outside until the food is close to the freezing point, in a rigid section, for cooling 9 to 3: and a means for surface cooling while injecting a refrigerant liquid at a mixing ratio of ethanol and propylene glycol within a range of 1 to 7 by volume, in the impregnation section, using a refrigerant liquid circulating means installed outside, in a ratio of 9 to 3: the mixing ratio of ethanol and propylene glycol in the range of 1 to 7 by volume ratio provides a constant temperature of the refrigerant liquid at-60 ± 5 ℃. And the freezing device uniformly freezes the product to be processed by maintaining the supply. Incidentally, the freezing unit is a frozen product to be frozen, packed in a plastic package and conveyed to the conveying conveyor 1, the conveying conveyor 1 being divided into predetermined standards or units, received in the basket through an entrance and entering the refrigerating unit to support the basket on both sides. This is a system where the freezing process is performed by means of a pre-cooling section- > a rigid section- > a submerged section by means of a chain conveyor, forming part of a moving cycle.

In this case, the freezing conveyors (120 a, 120b, 120 c) preferably use mesh conveyors which serve as temperature-resistant stainless mesh belts and which easily pass through the refrigerant.

And a driving shaft 123 is provided at one side of the plurality of freezing conveyors (120 a, 120b, 120 c) constituting the freezing conveyor 120, and is mounted to the rotational force of the driving motor 121 through a driven sprocket (123 a). The belts of the plurality of freezing conveyors (120 a, 120b, 120 c) are rotated by receiving a driving force of a chain (121 b) to be engaged with a driving sprocket 121a to be transmitted. That is, the plurality of freezing conveyors (120 a, 120b, 120 c) are simultaneously driven by the power of one driving motor 121.

Specifically, a plurality of freezing conveyors (120 a, 120b, 120 c) are made of the same size and installed such that input portions of food protrude to the outside to maintain a plurality of set intervals up and down in a multi-stage arrangement, a plurality of freezing conveyors rotate in opposite directions by connecting chains 121b to driven sprockets 123a of driving shafts 123 provided at one side of the conveyors (120 a, 120b, 120 c) in a zigzag manner, and a belt 122 of the freezing conveyor (e.g., 120 a) located at the upper side and a belt 122 of the freezing conveyor (e.g., 120 c) located at the lower side.

When the food is repeatedly transported in a zigzag manner, cooling is performed and the food is sequentially moved from the upper side to the lower side.

On the other hand, a quenching nozzle 132 for discharging a refrigerant for quenching food, which is used as an example of liquid nitrogen, is installed at an upper side of the freezing space 112, and thus the quenching nozzle supplies the liquid nitrogen filled in the liquid nitrogen storage tank 130 to the 132 th side for discharging. In this case, nitrogen, which is a binary atom with a gas element accounting for 80% by volume of air, is industrially available by fractional liquefaction of air, chemically a mixture of ammonium chloride and sodium nitrite. Obtained by fractional distillation by heating to 70 ℃ and then cooling the nitrogen to-196 ℃ to produce liquid nitrogen.

Such a quenching nozzle 132 is provided in plurality so as to face the surface of the uppermost freezing conveyor (120 a) to quench the food products (1) placed on the upper side of the freezing conveyor (120 a).

The feeding conveyor 140 is used to feed food to the upper part of the uppermost freezing conveyor 120a of the freezing conveyor 120, and is driven by separate driving motors (not independently driven). It consists of known first to third feed conveyors (140 a, 140b, 140 c).

More specifically, the input conveyor 140 is at a low inclination of 10 ° to 30 ° in order to easily put the food (1) into a state for breading treatment for wrapping raw meat (e.g., pork chops). The first input conveyor 140a is installed on the road, and the second input conveyor 140a is installed at a high inclination angle of 30 ° to 60 ° to convey the food 1 carried by the first input conveyor 140a to the inlet 114. The feed conveyor 140b and the food 1 carried by the second feed conveyor 140b are conveyed to a side of the uppermost freezing conveyor 120a constituting the freezing conveyor device 120. It includes a third feed conveyor 140c horizontally installed in the freezing space 112 of the freezing chamber 110.

Of course, it is apparent that the conveying means of the conveyor 140 may be composed of one or more conveyor conveyors depending on the field situation, and the degree of design variation is within the scope of the present invention.

The discharge conveyor 150 is a discharge port 116 of the freezing chamber 110, and conveys the food (1) that has fallen to the other lower side of the lowermost freezing conveyor (120 b) of the freezing conveyor 120. Which is used for discharging to the outside by an operator for packaging or the like, and known first and second discharge conveyors 150a, 150b are provided with separate drive motors (not shown) to be driven independently of each other. It consists of.

More specifically, the discharge conveyor 150 is a refrigerating chamber 110 for quickly freezing the finished food (1), which falls to another lower portion of the lowermost freezing conveyor (120 b) of the freezing conveyor 120. The first discharge conveyor 150a is horizontally conveyed to the outlet 116 of a), and the second discharge food 1 is conveyed to the outside of the freezing chamber 110 by the first discharge conveyor 150 a. It consists of a discharge conveyor (150 b).

Of course, it is understood that discharge conveyor 150 may be comprised of one or more discharge conveyors depending on the field situation, with varying degrees of design within the scope of the present invention.

In addition, a front surface of the freezing chamber 110, a worker freezing space 112 for repair in case of failure of the freezing conveyor 120, the quenching nozzle 132, and the air conditioner 160 is installed in the freezing space 112. An access door 118 is provided that can enter and exit the interior, and the refrigerated space 112 is provided with a temperature sensor 170 to monitor the temperature of the refrigerated space 112.

On the other hand, the control panel 180 is provided outside the freezing chamber 110 to control the freezing conveyor 120, the input conveyor 140, and the discharge conveyor 150. Of course, the control panel 180 monitors the temperature detected by the temperature sensor 170 to control the driving of the air conditioner 160. In this case, the liquefied nitrogen storage tank 130 may be provided with a manual valve to manually adjust the discharge amount of the filled liquefied nitrogen, and an electronic switching valve, which is controlled by the control panel 180 as necessary. The discharge amount of liquefied nitrogen can be adjusted.

In addition, the freezing chamber 110 prevents fine dust in the external air from entering the freezing space 112 of the freezing chamber 110 through the inlet 114 of the freezing chamber 110 by being buried in the food (1). An inlet 114 for an air curtain 141 is provided. Of course, the air curtain 141 is also driven by the control of the control panel (180).

Hereinafter, an operation example of the food quick-freezing apparatus according to the present invention will be described with reference to fig. 1 to 5.

The air conditioner 160 is driven such that the freezing conveyor 120, the conveying conveyor 140 and the discharge conveyor 150 are driven by the control panel 180 while the refrigerating compartment is maintained at a low temperature. .

In this state, when a worker places food such as pork on the conveyor 140 for feeding, the freezing conveyor introduces the food (1) to one side by positioning the inlet 114 of the freezing chamber 110 at the top (120 a) of the freezing conveyor 120.

Accordingly, the food 1 is transferred from one side to the other side of the freezing conveyor 120a located at the top thereof, and is rapidly frozen while the refrigerant liquid nitrogen sprayed through the quenching nozzle 132 is evaporated. In this case, the food 1 falls from the other end of the freezing conveyor 120a located at the top and is transferred to the other side of the freezing conveyor 120c located at the bottom thereof. At this time, the freezing conveyors (120 a, 120 c) positioned up and down rotate in opposite directions, and the belt conveys the food in opposite directions. Thus, this time it moves from the top of the other side of the freezing conveyor (120 c) to the top of one side.

When this process is repeated, the food 1 as a whole will move a long transport distance from the upper side to the lower side in a zigzag manner. In this case, when the plurality of freezing conveyors (120 a, 120b, 120 c) is composed of an odd number, the first input position and the last discharge position of the food (1) are different from each other.

On the other hand, the food dropped to the other side lower portion of the freezing conveyor (120 c) located at the lowermost end of the freezing conveyor 120 is conveyed to the discharge port 116 by the discharge conveyor 150, thereby enabling a worker after packing and the like. This process may be performed.

As described above, the embodiments of the present invention have been described in detail, but the scope of the present invention is not limited thereto, and extends to substantially the same scope as the embodiments of the present invention.
