Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a device for freezing food, and more particularly to a freezing device that is optimal for separating and freezing food separately.
[0002]
[Prior art]
Frozen foods can be conveniently used to separate and freeze separately rather than freezing into large blocks. This is because the amount can be easily separated. In order to freeze food in this state, a freezing apparatus has been developed in which a belt conveyor is provided in the freezer compartment. This freezing apparatus freezes food while transferring it on a belt conveyor that horizontally transfers a stainless steel net belt. Food is supplied to the belt conveyor in a state of being separated at one end. The supplied food is transferred into the freezer compartment by a belt conveyor, frozen in the freezer compartment, and discharged. The frozen food is scraped off by a scraper and separated from the belt conveyor.
[0003]
[Problems to be solved by the invention]
The above freezing apparatus has a drawback that a portion of the food is torn and adheres to the belt because the food frozen and adhered to the stainless steel belt is scraped off with a scraper. This worsens the product yield. Furthermore, the food remaining on the belt will deteriorate and deteriorate the sanitary environment. In particular, the endless belt conveyor belt is repeatedly circulated and frozen while transporting food, so that food that is frozen one after another is supplied on top of the rotten food. For this reason, when a food rots, the bad effect which reduces remarkably the quality of the frozen food will generate | occur | produce. Furthermore, the conveyor belt of the slit net cannot easily remove the attached food.
[0004]
Furthermore, the apparatus for transferring food by means of a stainless steel conveyor belt has a drawback of leaking from the stitches when food crushed small like minced meat is supplied. This also causes the leaked food to deteriorate the hygienic environment and reduce the food yield. If the stitches of the conveyor belt are made small in order to reduce the leakage of food, it becomes more difficult to remove foods clogged with fine stitches, and the sanitary environment is deteriorated. Moreover, even if the stitches of the conveyor belt are enlarged, it is difficult to completely remove the clogged food. Furthermore, if the stitches are made large, it becomes difficult to pull out from the stitches and separate them when the food that has entered the large stitches due to gravity and hangs down in a state where they are not frozen. This is because the scraper tears and separates the frozen food. To make matters worse, food that has entered the stitches and has been frozen freezes and expands and binds very strongly to the stitches. For this reason, when scraping with a scraper, it cannot be separated from the stitches, but is torn and separated with a scraper. In this way, the food remaining in the stitches deteriorates the quality of the frozen food due to corrosion or the like.
[0005]
Furthermore, the conventional freezing apparatus has a drawback that the food cannot be frozen in a clean shape. This is because a part of the food may be broken or broken when it is torn with a scraper. Further, since the frozen food is placed on a conveyor belt made of stainless steel and frozen, the bottom surface of the frozen food becomes a stitch pattern, which causes the frozen shape of the food to deteriorate.
[0006]
The present invention has been developed for the purpose of solving such drawbacks. An important object of the present invention is to provide a food freezing apparatus capable of freezing food in a very hygienic manner and capable of freezing small food so as not to leak.
Another important object of the present invention is to provide a food freezing apparatus capable of freezing food in a clean state without reducing the yield.
Furthermore, another important object of the present invention is to provide a food freezing apparatus capable of freezing liquid or pasty food if necessary.
[0007]

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. However, the examples shown below exemplify food freezing devices for embodying the technical idea of the present invention, and the present invention does not specify food freezing devices as described below.
[0013]
Further, in this specification, in order to facilitate understanding of the scope of claims, the numbers corresponding to the members shown in the embodiments are referred to as “claims” and “means for solving the problems”. It is added to the member shown by. However, the members shown in the claims are not limited to the members in the embodiments.
[0014]
The food freezing apparatus shown in FIGS. 1 and 3 is provided with a conveyor 2 in a freezer compartment 1. The conveyor 2 includes a horizontal base 3 that is fixed horizontally to the freezer compartment 1, a plastic film 4 that is placed so as to be movable on the horizontal base 3, and a drive mechanism 5 that moves the plastic film 4. Prepare.
[0015]
The freezer compartment 1 is closed by a heat insulating wall 6 and a cold air device 7 is disposed inside. The cold air device 7 cools the inside of the freezer compartment 1 and freezes the food S carried on the plastic film 4 and carried into the freezer compartment 1. As shown in FIGS. 1 and 2 or as shown in FIGS. 3 and 4, the cold air device 7 forcibly blows cold air on the upper surface of the plastic film 4 and the lower surface of the horizontal table 3 to freeze the food S. . In particular, in the cool air device 7 shown in FIGS. 1 and 2, the forcedly cooled cooling air creates a flow parallel to the direction in which the plastic film 4 is transferred. There is a feature that can be transferred.
[0016]
The cold air device 7 includes an air cooling heat exchanger 8 and a fan 9 that forcibly blows air to the air cooling heat exchanger 8. The air cooling heat exchanger 8 has heat radiating fins such as aluminum fixed to a metal pipe through which a refrigerant passes. The fan 9 forcibly circulates air through the air cooling heat exchanger 8 to cool the air. The freezing apparatus shown in FIG. 2 and FIG. 4 is provided with a space 10 through which air can pass on both sides of the horizontal table 3 and the plastic film 4, and air is passed through the space 10 to move the food S on the plastic film 4 up and down. Cool from. Since this freezing apparatus has the space 10, the operator can move here. For this reason, the food S can be managed conveniently inside.
[0017]
The air cooling heat exchanger 8 is connected to the condenser 12 and the compressor 13 via the expansion valve 11, and the refrigerant circulating inside is used as the air cooling heat exchanger 8 → the compressor 13 → the condenser 12 → the expansion valve 11. → Circulate through the air cooling heat exchanger 8. The compressor 13 and the condenser 12 are disposed outside the freezer compartment 1. The expansion valve 11 is disposed in the vicinity of the air cooling heat exchanger 8, for example, in the freezer compartment 1. The compressor 13 pressurizes the gaseous refrigerant discharged from the air cooling heat exchanger 8. The pressurized gaseous refrigerant is cooled by the condenser 12 and liquefied. The condenser 12 is a water-cooled or air-cooled heat exchanger. Similarly to the air cooling heat exchanger 8, the condenser 12 also has heat radiation fins fixed to the metal pipe, or a metal pipe into which cooling water flows. The expansion valve 11 controls the flow rate at which the pressurized, cooled, and liquefied refrigerant is adiabatically expanded and vaporized by the air cooling heat exchanger 8. This cooling mechanism pressurizes a gaseous refrigerant with a compressor 13 and liquefies it with a condenser 12, vaporizes the liquefied refrigerant with an air cooling heat exchanger 8, and cools the air in the freezer compartment 1 with heat of vaporization. To do.
[0018]
Furthermore, the freezing apparatus shown in FIGS. 1 and 2 includes a fan 30 that blows cooling air downward above the horizontal table 3. In the illustrated freezing apparatus, a plurality of fans 30 are spaced apart from each other in the direction in which the plastic film 4 is transferred, and arranged at equal intervals. These fans 30 blow cooling air to the upper surface of the plastic film 4 that is transferred on the upper surface of the horizontal table 3. Thus, the fan 30 that blows the cooling air directly to the food S has the feature that the food S can be efficiently frozen from the surface.
[0019]
The horizontal table 3 has an upper surface that contacts the plastic film 4 as an uneven surface 24. This is because water between the plastic film 4 and the horizontal base 3 strongly attaches the plastic film 4 and the horizontal base 3 at room temperature, and also prevents freezing and freezing of the plastic film 4 on the horizontal base 3. In the freezing apparatus of the present invention, the plastic film 4 is not strongly attached to the horizontal base 3 or frozen in a state where it is normally used. This is because the freezer compartment 1 is cooled to a negative temperature and the plastic film 4 is continuously moved. The plastic film 4 strongly adheres to the horizontal table 3 or freezes when the freezing device is stopped and then restarted. When the freezing device is stopped, the temperature of the freezer compartment 1 becomes a plus temperature. In this state, condensed water and frozen ice are dissolved to generate water. This water enters between the plastic film 4 and the horizontal base 3. Since this water strongly adheres the plastic film 4 and the horizontal base 3 to each other due to surface tension or the like, the plastic film 4 does not move and is damaged when pulled forcibly. Alternatively, in this state, when the freezer compartment 1 is cooled to minus to start the apparatus, water between the plastic film 4 and the horizontal base 3 freezes, and this fixes the plastic film 4 to the horizontal base 3. When the plastic film 4 is driven in this state, the plastic film 4 frozen on the horizontal base 3 does not move, and it is also damaged when pulled forcibly.
[0020]
This adverse effect can be prevented by moving the plastic film 4 while performing the freezing operation without using the freezing device. However, if the plastic film 4 is moved when not in use, the plastic film 4 is wasted and the running cost increases. The freezing apparatus of the present invention eliminates this problem by setting the horizontal table 3 to the concave / convex surface 24 or providing a clearance 29 therethrough. The horizontal table 3 having the unevenness and the gap 29 moves the water on the horizontal table 3 to the recess 24 </ b> B or drops it from the gap 29. For this reason, water is not interposed between the plastic film 4 and the horizontal base 3, the plastic film 4 can be moved even at room temperature, and water freezes to freeze the plastic film 4 to the horizontal base 3. There is nothing.
[0021]
As shown in the plan view of FIG. 5 and the end view of FIG. 6, the horizontal table 3 shown in FIGS. The horizontal table 3 is manufactured by pressing a stainless plate. The metal plate is partially provided with a convex portion 24 </ b> A to form an uneven surface 24. The convex portion 24A is preferably circular or elliptical, and the upper surface is planar. This is for easy and clean cleaning and hygiene. The outer diameter of the circular convex portion 24A or the long diameter of the elliptical convex portion is 5 mm to 50 mm. Since the horizontal table 3 collects water between the convex portions 24A, the water remaining on the horizontal table 3 does not attach the plastic film 4 to the horizontal table 3 strongly or freeze it.
[0022]
Further, as shown in the plan view of FIG. 8 and the enlarged sectional view of FIG. 9, the horizontal base 3 of the freezing apparatus shown in FIG. Are fixed by welding. An airtight chamber 27 for allowing a cooling fluid to pass is provided between the upper plate 26 and the lower plate 25 by welding the concave portion 24 </ b> B of the upper plate 26 to the lower plate 25. The horizontal platform 3 is cooled by passing a cooling fluid through the hermetic chamber 27. The horizontal table 3 is provided with an airtight chamber 27 in which the upper plate 26 and the lower plate 25 are locally welded and hermetically closed between the upper plate 26 and the lower plate 25. Pressurized gas is injected to manufacture the upper plate 26 with an uneven shape. The upper plate 26 and the lower plate 25 are welded by laser welding or seam welding.
[0023]
In FIG. 8, a portion indicated by a black dot is a portion where the upper plate 26 and the lower plate 25 are locally welded. Further, in the horizontal table 3 shown in FIG. 8, the upper plate 26 and the lower plate 25 are connected by a plurality of linear connecting portions 31 to form the airtight chamber 27 as one continuous flow path. The linear connecting portion 31 is provided by welding the upper plate 26 and the lower plate 25 linearly from both side edges toward the center. The plurality of linear connecting portions 31 are alternately provided on both sides of the horizontal base 3 so that the cooling fluid passes through the hermetic chamber 27 as one continuous flow path as indicated by arrows in the figure. I am letting.
[0024]
The horizontal table 3 can supply a refrigerant as a cooling fluid to the hermetic chamber 27, vaporize the refrigerant in the hermetic chamber 27, and forcibly cool the horizontal table 3 with the heat of vaporization of the refrigerant. Similar to the air-cooling heat exchanger 8, the horizontal base 3 having this structure provides a refrigerant circulation path with an airtight chamber 27, a compressor, a condenser, and an expansion valve. The refrigerant is pressurized by a compressor, liquefied by a condenser, and vaporized by an airtight chamber 27 of the horizontal table 3 to cool the horizontal table 3.
[0025]
It is also possible to supply a cooling liquid as a cooling fluid to the hermetic chamber 27 and forcibly cool the horizontal table 3 with this cooling liquid. The horizontal table 3 that forcibly cools the airtight chamber 27 by flowing a cooling fluid can cool the food S more efficiently through the plastic film 4. A cooling liquid such as a brine liquid is cooled by a cooling device (not shown) provided separately. The cooled coolant is circulated through the airtight chamber 27 of the horizontal table 3. As the cooling liquid, a brine liquid that does not freeze at 0 ° C. or lower is used. As described above, the freezing device that forcibly cools the horizontal table 3 can efficiently cool the food S to be transported on the plastic film 4. Also in this freezing device, a cold air device 7 is arranged in the freezer compartment 1 to cool the horizontal table 3 while cooling the air. However, the freezing apparatus that supplies and cools the refrigerant to the airtight chamber 27 of the horizontal table 3 does not necessarily need to be provided with an air cooling heat exchanger in the freezer compartment 1. As shown in FIG. 3 and FIG. 4, by fixing the cooling fins 14 to the lower surface of the horizontal table 3 and cooling the air with the cooling fins 14, the horizontal table 3 can be used as an air cooling heat exchanger. is there.
[0026]
Furthermore, the horizontal base 3 in FIGS. 10 and 11 has a plurality of metal rods 28 arranged in parallel on the same plane. The horizontal table 3 has a gap 29 between the metal rods 28. The gap 29 in the horizontal table 3 passes and drops the water generated above. For this reason, water does not accumulate on the horizontal base 3, and water does not adhere the plastic film 4 strongly or freeze. The metal rod 28 can be a metal pipe. The horizontal table 3 is airtightly connected to the inside of the metal pipe to form an airtight chamber 27, and is cooled by flowing a cooling fluid therein. As the cooling fluid, a refrigerant can be used. The refrigerant can be vaporized in the airtight chamber 27 and the horizontal table 3 can be forcibly cooled by the heat of vaporization of the refrigerant. Alternatively, the horizontal base 3 can be forcibly cooled by using a cooling fluid as a cooling liquid and connecting a metal pipe with the cooling liquid.
[0027]
As shown in FIG. 12, the horizontal table 3 may be a perforated plate in which a number of through holes are provided in a metal plate such as stainless steel. The horizontal table 3 is a gap 29 through which water passes. Therefore, the water accumulated on the horizontal table 3 falls through the horizontal table 3 from the through hole. Furthermore, the apparatus which blows cooling air up and down using the horizontal base 3 as a perforated plate can freeze food efficiently with cooling air. This is because the cold air directly cools the plastic film 4 and cools the food S placed thereon.
[0028]
As shown in FIGS. 3 and 4, the horizontal table 3 can fix the cooling fins 14 made of a metal plate on the lower surface. In particular, a horizontal base provided with an airtight chamber inside and forcedly cooled by flowing a cooling fluid therein can cool the air in the freezer compartment efficiently with cooling fins, although not shown. Moreover, the horizontal base 3 without an airtight chamber is provided with the cooling fins 14 so that the horizontal base 3 can be efficiently cooled by the connection air.
[0029]
The freezing apparatus shown in FIGS. 1, 3, 7 and 12 is a winding guide 15 for the plastic film 4 and a folding guide for separating the food S from the plastic film 4 by transferring the plastic film 4 to be bent. 16 is disposed outside the freezer compartment 1, and the frozen food S is separated from the plastic film 4 outside the freezer compartment 1. Further, in this freezing apparatus, the supply shaft 17 of the plastic film 4 is also disposed outside the freezer compartment 1, and the food S is supplied to the plastic film 4 outside the freezer compartment 1. The freezing apparatus that supplies the food S onto the plastic film 4 outside the freezer 1 and further separates the frozen food S from the plastic film 4 outside the freezer 1 is fixed horizontally inside the freezer 1. The horizontal platform 3 is extended from the entrance to the exit of the plastic film 4. Further, a supply plate 18 and a discharge plate 19 are also fixed horizontally outside the freezer compartment 1 in the same plane as the horizontal table 3.
[0030]
The freezing apparatus of the present invention is mainly used for freezing loose foods such as minced meat, beans, and corn, but can also be used for freezing liquid foods such as soup and broth. As shown in the cross-sectional views of FIGS. 2 and 4, this freezing apparatus is provided with side walls 20 on both sides of the horizontal table 3, the horizontal table 3 having a groove shape, and the plastic film 4 having a groove shape thereon. Transport. The plastic film 4 can be transported so as not to leak to both sides by supplying a liquid. The liquid frozen by the plastic film 4 can be crushed and separated on the discharge side.
[0031]
The plastic film 4 is a thin film having excellent low temperature characteristics such as a polyethylene film and polypropylene. For example, a plastic film 4 having a thickness of 10 to 100 μm, preferably 10 to 50 μm, more preferably 10 to 30 μm is used. Since the plastic film 4 is used once and discarded, a thin film is used as much as possible to reduce the running cost. In addition, the thin plastic film 4 has an advantage that the food S can be efficiently cooled through the horizontal table 3 that is forcibly cooled. However, if the thickness is too thin, the strength will decrease.
[0032]
The roll of plastic film 4 is mounted on the supply shaft 17 and pulled out to the horizontal table 3. The plastic film 4 passing over the horizontal table 3 is transferred at a constant speed. The plastic film 4 is wound around the winding shaft 15 and passed over the horizontal table 3 at a constant speed. In this freezing, the winding shaft 15 is driven by the servo motor 21. The servo motor 21 rotates the winding shaft 15 in the winding direction at a rotation speed at which the plastic film 4 can be transferred at a constant speed regardless of the winding diameter of the plastic film 4. This freezing device is connected to a take-up cylinder 22 that is mounted so as not to rotate on the take-up shaft 15 so that the leading edge of the plastic film 4 does not slip, and the take-up shaft 15 is driven by a servo motor 21. The servo motor 21 moves the plastic film 4 at a constant speed by reducing the rotation speed of the winding shaft 15 as the winding diameter of the plastic film 4 increases. When the plastic film 4 is wound on the winding cylinder 22 to a predetermined thickness, the winding cylinder 22 is replaced with a new one.
[0033]
The folding guide 16 separates the frozen food S from the plastic film 4. The folding guide 16 of the freezing apparatus shown in the figure is a roller 23. The roller 23 moves the plastic film 4 so as to be bent about 180 degrees, and separates the frozen food S from the surface of the plastic film 4. The frozen food S does not adhere to the plastic film 4 so firmly. For this reason, the food S can be easily separated from the plastic film 4 by bending the plastic film 4. Since the folding guide 16 can be transferred so as to bend the plastic film 4, it can be made of a metal rod or a metal plate having a small frictional resistance without using a roller. These folding guides 16 make the sliding surface with the plastic film 4 smooth as a smooth surface and preferably constitute the sliding surface with a small frictional resistance such as a fluororesin.
[0034]
Furthermore, the food S on the plastic film 4 can be separated by scraping with a scraper regardless of the folding guide 16. In addition, the food S can be separated from the plastic film 4 by both the scraper and the folding guide 16. In this freezing apparatus, the scraper is elastically pressed against the plastic film 4 transferred in contact with the folding guide 16 to separate the food S.
[0035]
The folding guide 16 which is the roller 23 can also be used as a driving roller for transferring the plastic film 4 at a constant speed. This freezing device rotates the driving roller at a constant speed to transfer the plastic film 4 at a constant speed. The take-up shaft 15 takes up the plastic film 4 transferred by the driving roller via the clutch. Furthermore, although not shown, in order to transport the plastic film at a constant speed, the plastic film can be sandwiched and transported by a capstan roller. In this freezing apparatus, a capstan roller is rotated at a constant speed by a servo motor, and a plastic film is transferred at a constant speed. Also in this freezing apparatus, the take-up shaft takes up a plastic film that is transferred at a constant speed via a clutch.
[0036]
【The invention's effect】
The food freezing apparatus of the present invention has an advantage that food can be frozen very hygienically and small food can be frozen so as not to leak. The food freezing apparatus according to the present invention includes a conveyor for transferring the supplied food, a horizontal base, a plastic film disposed on the horizontal base, and a drive mechanism for moving the plastic film. This is because the food is supplied on the plastic film and the supplied food is frozen by moving the plastic film. As described above, the freezing apparatus for transferring food with a plastic film has various adverse effects caused by the food remaining firmly attached to the belt, like a conventional apparatus for transferring food with a stainless steel belt or a belt having stitches. Can be eliminated. For this reason, the freezing apparatus of this invention can implement | achieve provision of a safe and high quality foodstuff, without freezing food quality very hygienically and reducing the quality of foodstuff.
[0037]
Furthermore, since the freezing apparatus of the present invention supplies food to a plastic film and freezes it, it can be transported and frozen so that even small food does not leak, and if necessary, it can be liquid or pasty food. However, it has the feature that it can be frozen very hygienically without leaking downward.
[0038]
Furthermore, the freezing apparatus of the present invention has a feature that it can be separated from the plastic film very easily and neatly because the food is transferred and frozen by the plastic film. For this reason, the freezing apparatus of the present invention can reliably prevent a part of the food from being torn and damaged when separating the food as in the past, and the food is in a clean state without reducing the yield. There is also a feature that can be frozen with.
[0039]
Furthermore, the freezing apparatus of the present invention can effectively prevent the plastic film from strongly adhering to the horizontal base or freezing when restarting after stopping. This is because the horizontal table has an uneven surface or a gap is provided in the horizontal table. This horizontal platform allows water accumulated on it to flow into the concave portion of the concave-convex surface or to pass through the gap and drop it. For this reason, it can prevent reliably that the water on a horizontal stand contacts a plastic film, and this adheres strongly or freezes. For this reason, the freezing apparatus of the present invention has a feature that the plastic film can be smoothly moved when stopped and restarted. This also realizes the feature that the running cost can be reduced by using a thin plastic film. This is because the tensile strength required for the plastic film can be lowered because the plastic film can be started with a light tensile force.
