Description

Apparatus for Crushing and Thawing of Frozen Product Having Transfer Means}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an apparatus for crushing and thawing frozen products such as frozen cream, and more particularly, when a frozen product such as frozen whipped cream is added, it is automatically crushed and warmed up as a product in liquid form. By discharging, it is possible to automatically crush and dissolve large quantities of frozen product automatically and continuously to provide the liquid product in subsequent product processes, as well as to collect and disintegrate the crushed product downstream of the crusher to a narrow outlet. It is related with the frozen product crushing ice-breaking apparatus provided with the new conveying mechanism which makes it easy to convey a crushed product by providing a rotating conveying mechanism.

Generally, fresh cream refers to a component of milk fat separated from ingredients contained in milk. In general, large food companies store fresh cream, which is used as a raw material in other processes, in a solid state in an environment of about -18 ° C. or lower. In this case, the fresh cream is, for example, about 20kg to 25kg, and is generally made of a plastic film in the form of a cube Stored frozen in packs.

Afterwards, the fresh cream is stored in a liquid state at a temperature of -18 ° C or below in a freezer to be added to a liquid state for subsequent processing, such as to control milk fat ratio or to provide other foods. It should thaw. However, when the fresh cream is heated at 65 ° C. or higher during the thawing process, the fresh cream may not only lose its freshness, but also may change its taste or flavor, and the color may change to yellow. Therefore, temperature control is essential when thawing fresh cream.

Conventionally, when thawing such frozen fresh cream, it is common to use a method of dissolving a frozen fresh cream pack in a large container with hot water. This method requires a lot of space for thawing, difficult to control the temperature, it takes a long time to melt all the frozen solid cream, which is a large solid mass, and it requires a lot of manpower, which raises labor costs and sanitizes the products before and after thawing. There was a problem that the management process to deal with the cumbersome and inconvenient.

Therefore, there have been attempts to automate the thawing process of frozen products, such as frozen fresh cream, to solve these problems. For example, Japanese Patent Laid-Open No. 2000-157180, Japanese Patent Laid-Open No. 2003-135005, and Japanese Patent Laid-Open No. 2005-151951 are used to thaw a product such as a frozen ice cream in a pack or a pocket with a plate heater, or Disclosed are devices for shredding with a roller, or for pressing after shredding by heating a certain distance. However, these conventional fracturing and / or thawing devices for frozen fresh cream and the like are devices that process the product together with the pack, which includes extracting the thawed product from the pack by pressing on at least both sides of the pack. Accordingly, these conventional devices had to be of a compact and relatively thin thickness in the form of a refrigeration pack that could be processed. This results in a rapid and hygienic thawing of frozen products, such as frozen fresh cream, usually in the form of lumps in the form of thick cubes, such as when a relatively large food manufacturing company requires large amounts of frozen fresh cream. There was a limitation that it could not be used as a supplyable device.

Therefore, there is still a need for a frozen product thawing technology that is configured to rapidly and hygienicly thaw frozen products and continuously supply them in large quantities.

The present invention has been made in order to supplement the problems of the prior art described above and to provide a variety of additional advantages, in particular by inputting a frozen product such as frozen fresh cream automatically crushed and then warmed up to be discharged as a liquid form product, In addition to automatically and rapidly crushing and dissolving large quantities of frozen product, the liquid product can be continuously supplied to subsequent product processes, as well as rotating conveying mechanisms to collect and disintegrate the crushed product downstream of the crusher to a narrow outlet. It is an object of the present invention to provide a frozen product crushing and thawing apparatus having a new conveying mechanism that facilitates the conveyance of crushed products.

These objects are achieved by a frozen product fracturing thawing apparatus with a conveying mechanism provided according to the invention.

Frozen product crushing ice-breaking apparatus provided with a conveying mechanism provided according to an aspect of the present invention, in order to crush and warm the frozen product in the form of a relatively low temperature solid mass, to discharge as a product in a relatively high temperature liquid form, A crusher for crushing the product in a lump form; A hot water supply unit for circulating relatively hot water; And a tube jacket for dissolving the product crushed by the crusher by applying heat of hot water to the hot water supply unit, wherein the crusher has a crushing knife and a case rotating to crush the product. A case body surrounding the shredding knife and an auxiliary portion connected thereto; In the upper half of the case body, the product in the form of a solid mass slips by gravity and is introduced into the shredding knife, and the product shredded by the shredding knife is connected to the lower part through the lower part of the case body by gravity below. Discharged into the interior space and then discharged through a relatively narrow diameter product outlet; Within the auxiliary part, a transport mechanism that rotates to collect and push the crushed product toward the product outlet may be installed.

In one embodiment, the transfer mechanism may be in the form of a screw in which a spiral blade of a predetermined direction is formed around one rotation axis.

In another embodiment, the transfer mechanism may be in the form of a paddle in which a plurality of flat paddles are fixed rotationally symmetrically about one rotation axis.

The present invention according to the above configuration, a large amount of liquid product can be automatically hygienically supplied to the continuously necessary process, so that the manpower is reduced and the time is saved to improve the productivity. Specifically, the present invention is configured to automatically crush and warm the frozen product, such as frozen fresh cream, and then discharged as a liquid form product, thereby automatically crushing and dissolving a large amount of frozen product quickly and liquid product. Not only can be provided continuously to subsequent product processes, but also has a conveying mechanism that rotates to collect the shredded product downstream of the shredder and transport it to the narrow outlet, thereby facilitating the transport of the shredded product.

In addition, the present invention is to crush the product in the form of a relatively low temperature agglomeration of less than about -18 ℃, and thawed by contacting the crushed product with hot water of a predetermined temperature in a heat exchange method to relatively high liquid of about 40 ~ 65 ℃ By discharging part of the hot liquid product to the cold shredder and / or further to circulate hot water to the shredder, so that the temperature of the components involved in the shredding process is not lowered relatively. Rather, it provides a significant effect, such that the crushed product arising from the crushing process is partially dissolved and / or mixed with the product in liquid form to make it a semi-liquid state that is easy to transport.

Hereinafter, with reference to the accompanying drawings illustrating the present invention with a specific example as follows.

The frozen product shredded thawing apparatus 10 of the present invention, such as the example shown in FIGS. 1 to 8, is a device for shredding and thawing frozen products in the form of relatively low-temperature solid masses and discharging them as a liquid liquid product. In particular, it is characterized in that it comprises a conveying mechanism that rotates in the case 30 of the crusher 12.

The product that is crushed and thawed in the frozen product crushing thawing apparatus 10 of the present invention is, for example, a product that exists in a solid state at −18 ° C. or lower and changes to a liquid state at or above room temperature, and may include, for example, fresh cream. . However, it is obvious that the product which can be treated by the present invention does not need to be limited to fresh cream, but can also be used as an apparatus for crushing and thawing frozen ice cubes, for example. Therefore, the term 'product' in the present specification should be interpreted to include all products that change into a solid state and a liquid state by temperature change.

The product P processed in the frozen product crushing and thawing apparatus 10 according to the embodiment described below with reference to the drawings includes fresh cream. Fresh cream is usually stored in a pack at a low temperature of −18 ° C., for example, generally as a solid mass of cuboids, and must be thawed to a temperature above room temperature before use in subsequent processes. On site, the worker removes the frozen product (A) from the pack from the freezer store, leaves it at room temperature for about 1 hour, then removes the pack and freezes the frozen product (A) in the form of a solid mass. It can be put into the crusher 12 of the. The liquid product that is thawed and discharged by the frozen product crushing and thawing device 10 is preferably controlled at a temperature such that the flavor and taste of the frozen product are not changed, as in the case of frozen fresh cream, and is about 40 to 65 ° C. It can be adjusted to have a temperature of.

1 and 2, the frozen product crushing thawing apparatus 10 may include a crusher 12, a tube jacket 14, and a hot water supply unit 16. The product P passes through the crusher 12 and is changed from the frozen product A in the solid state to the crushed product B in the form of small grains or a liquid mixed therein, and further the tube jacket 14 ) Is changed into a liquid product (C) in the liquid state. The temperature of the liquid product C can be controlled by adjusting the temperature of the hot water from the hot water supply unit 16 supplied to the tube jacket 14.

Figures 3 and 4 schematically show the overall shape of an example of the actual configuration of the frozen product shredded ice thawing apparatus 10 according to the present invention, Figures 5 and 6 shows the crusher 12 portion of them in more detail.

As shown, the shredder 12 includes a cylindrical shredding knife 20 and the case 30 is fixed to both ends of the rotating shaft to rotate. The case 30 may include a case body 30a surrounding the shredding knife 20 and an auxiliary part 30b providing an auxiliary space for temporarily storing the shredded product B.

According to the present invention, the shape of the case body 30a is formed in such a manner as to ensure that the liquid product C flowing into the shredder 12 is mixed with the shredded product B while making contact with the surface of the shredded knife 20. It is characterized by. To this end, the inner shape of the case body 30a preferably corresponds to the outer shape of the shredding knife 20.

In other words, in the illustrated example, the shredding knife 20 may be of a side lying cylindrical shape with a plurality of blades rotating by one axis of rotation. In this case, the case main body 30a also has a cylindrical shape similar to the shredding knife 20, and the distance W between the shredding knife 20 and the case main body 30a is preferably very narrow. The size of this gap W may be, for example, about 1 to 15 mm.

The upper half of the cylindrical case body (30a) is provided with a product inlet 31 which is an opening that is open to the frozen product (A), the lower part of the case body (30a) is also opened so that the crushed product (B) is discharged The product outlet 32 is provided. In addition, at least one inlet 33 may be formed at an upper portion of the case body 30a to allow the liquid product C to flow therein, such that the product circulation path 18 may be connected. In addition, the upper half of the case body 30a may be provided with a maintenance door 34 at a position opposite to the product inlet 31.

The auxiliary part 30b extends vertically downward from the product outlet 32 under the case body 30a vertically, and has a round bottom surface and may have a generally cylindrical shape. The auxiliary part 30b forms an auxiliary space 35 in which the crushed product B falling from the case body 30a temporarily stays, and a product discharge port 36 through which the crushed product B is discharged is formed at the lower end thereof. The product outlet 36 may be an opening having a relatively small and narrow diameter compared to the size of the auxiliary space 35, and may be connected via the tube jacket 14 and the tube-shaped transfer tube T1.

According to the invention, in this shredder 12, as illustrated in FIGS. 5 to 8, the shredded product B temporarily stored in the auxiliary part 30b is pushed into the relatively narrow product outlet 36. The rotating transfer mechanism 50 is further provided.

The transfer mechanism 50 may be a screw-type transfer screw in which a spiral blade 53 'in a predetermined direction is formed around one rotation shaft 51, and more preferably, one rotation shaft 51 The plurality of flat paddles 53 may be a paddle-shaped conveying paddle that is rotationally symmetrically fixed.

The conveying mechanism 50 in the form of a conveying screw and / or a conveying paddle is generally driven by a rotary pump 13 (see FIG. 2) by pushing the crushed product B out of the crusher 12 and conveyed toward the tube jacket 14. In addition to the power means such as) may provide further power for the transfer.

Referring to FIG. 7, the conveying mechanism 50 in the form of a conveying screw has a rotary blade 53 composed of two spiral blades 531 and 533 wound in opposite directions with respect to a position of an outlet, that is, a product outlet 36. ') May be formed on the rotation shaft 51. As the rotary shaft 51 of the feed mechanism 50 in the form of a feed screw rotates, the spiral blades 531 and 533 wound in opposite directions about the outlet port are rotated, and are caught in the gap between the rotary blades 531 and 533. The crushed product B can be moved in the longitudinal direction of the rotary shaft 51.

If the product powder or granules constituting the crushed product (B) have a uniform size, such a transfer screw type transfer mechanism 50 may be usefully applied. However, in the case where the shredding knife 20 of the shredder 12 continuously processes the plurality of frozen products A, in the part where two adjacent frozen products A are in contact with each other, the particle size of the shredded product May be irregular, and crushed product particles having an irregular shape and relatively larger in size than the normal crushed product particles may be introduced into the auxiliary space 35. Such irregular shapes and large sized particles may be caught between the spiral blades 531 and 533 of the transfer mechanism 50 in the form of a transfer screw, and as a result, there is a problem that prevents rotation of the transfer mechanism 50 in the form of a transfer screw. Can occur.

The problem caused by such irregular crushed product particles can be solved by the transfer mechanism 50 in the form of a transfer paddle as illustrated in FIG. 8. The transfer mechanism 50 in the form of a transfer paddle may have a structure in which a plurality of flat paddles 53 are fixed in a rotationally symmetrical manner about a rotating shaft 51 that rotates. The paddle 53 may be attached in a cross shape as illustrated in FIG. 8B, but the illustrated example is only one embodiment and may be attached in other forms.

When the axis of rotation 51 of the transfer mechanism 50 in the form of a transfer paddle rotates, the flat paddles 53 are made of the crushed product B, unlike the spiral blades 531 and 533 pushing the particles of the crushed product B. ) And collide with particles. Due to this collision, the particles of the crushed product B can be broken into smaller sizes. That is, even a relatively large crushed product particle having an irregular shape may be broken into small pieces while colliding with the paddle 53 of the transfer mechanism 50 in the form of a transfer paddle. In addition, the crushed product particles may be discharged by being pushed to the product outlet 36 formed at the bottom of the auxiliary space 35 by the rotation of the transfer mechanism 50 in the form of a transfer paddle.

On the other hand, in the frozen product crushed thawing apparatus 10 provided in accordance with the present invention, the crusher 12 is a device to make a crushed product (B) by inputting and crushing the product in a solid lump state, that is, frozen product (A).

Generally, frozen product (A) is generally a block of cuboids, the temperature of which may be about -18 ° C. As the crusher 12 proceeds with the processing of the frozen product A, the temperature of the crusher 12 itself is lowered to sub-zero temperature instead of room temperature. When the temperature of the crusher 12 is lowered to below zero, the crusher 12 ), The operation of the parts (particularly shredding knife) may not be made smoothly, the life of the parts may be shortened. In addition, since the product crushed in the crusher 12, ie, the crushed product B, is maintained in the state of solid grains or powders, the rotation of the transfer mechanism 50 may be prevented, and consequently, transfer to the next step, that is, the tube jacket 16. It may be difficult to do.

Therefore, the temperature of the shredder 12 is not lowered below freezing, preferably kept at room temperature, and furthermore, such that the state of the shredded product B discharged by the shredder 12 is in a semi-liquid state. By doing so, an action for smoothly performing the operation of the transfer mechanism 50 is required. In order to meet this demand, the present invention includes a structure in which hot water is circulated outside the crusher 12. In addition, a structure may be installed such that a portion of the relatively hot liquid product C discharged by the tube jacket 14 is introduced into the crusher 12.

In other words, according to one embodiment of the present invention, the shredder 12 may be supplied with hot water from the hot water supply unit 16. As shown in FIG. 1, the hot water from the hot water supply unit 16 is supplied to the tube jacket 14, and the hot water discharged from the tube jacket 14 is supplied to the crusher 12 and discharged from the crusher 12. The hot water may form a circulation path that returns to the hot water supply unit 16 again. To this end, the shredder 12 may be provided with a warm water jacket 40.

In addition, according to another embodiment of the present invention, the shredder 12 may be returned to some of the liquid product (C) discharged from the tube jacket (14). As shown in FIG. 2, some of the liquid product C exiting the tube jacket 14 may enter the crusher 12 through the product circulation path 18.

The tube jacket 14 has a product flow path 142 and a warm water flow path 144, as shown in FIG. The product flow path 142 is a path through which the crushed product B flowing out of the crusher 12 is moved, while the hot water flow path 144 is a path through which hot water supplied from the hot water supply unit 16 flows. The product flow path 142 and the hot water flow path 144 are adjacent to each other in heat exchange, but separate paths from each other so that the product and the hot water flowing therein do not mix with each other.

The hot water supply unit 16 includes a steam supply path 161 for supplying steam and a water supply path 162 for supplying water, and further, to adjust the temperature of the supplied steam and water to supply the hot water at a predetermined temperature. And a centrifugal pump 164 for the transfer of hot water. The hot water supplied from the hot water supply unit 16 to the tube jacket 14 is supplied to the hot water jacket 40 of the crusher 12 through the hot water circulation path 165, and then transfers heat to the crusher 12, and then again. Return to inline heater 163.

2 shows a piping diagram of a frozen product shredded thawing apparatus 10 having a warm water jacket according to an embodiment of the present invention. As shown, the piping constituting the frozen product crushing thawing apparatus 10 may be divided into a path that the product is transported and a path through which hot water for heat supply flows.

The hot water flow path may form a circulation path including the hot water supply unit 16, the tube jacket 14, and the crusher 12, as in the illustrated example. That is, hot water circulates through the in-line heater 163 of the hot water supply unit 16, the centrifugal pump 164, the hot water flow path 144 of the tube jacket 14, the hot water circulation path 165, and the hot water jacket 40. . The circulating power of the hot water is provided by the centrifugal pump 164, and the temperature control of the hot water can be provided by the inline heater 163.

The path through which the product is conveyed, as illustrated, includes a shredder 12 and a tube jacket 14. The product is fed into the crusher 12 as frozen product A, crushed, and then discharged as crushed product B. In the example shown, the crushed article B is connected to the tube jacket 14 via a tube like feed tube T1 by means such as a rotating screw (not shown) or by means such as a rotary motor 13. Can be delivered. When the crushed product (B) is introduced into the tube jacket 14, it is transferred over the length of the tube jacket (14) to absorb heat to increase the temperature to change into a liquid product (C) in the liquid state. Downstream of the tube jacket 14 is connected another delivery tube T2 which allows the liquid product C to be discharged and transferred to the subsequent process.

In the illustrated example, the downstream of the crusher 12 and the upper end of the tube jacket 14 are connected by a separate transfer pipe T1, but an example of directly connecting without the separate transfer pipe T1 is also possible. However, when the crusher 12 and the tube jacket 14 are directly connected to each other, the shape of the crusher 12 and the tube jacket 14 must be newly created as a dedicated part, and there is a disadvantage in that an existing common part cannot be used. The feed tube T1 can provide the advantage of saving manufacturing costs by allowing the shredder 12 and the tube jacket 14 to be configured as shared components.

According to a preferred embodiment of the present invention, the frozen product shredding thaw apparatus 10 may further include a product circulation path 18 and / or a hot water jacket 40.

The product circulation path 18 is a path for returning, for example, the liquid product C at 40 to 65 ° C. from the tube jacket 14 to the shredder 12 which processes the frozen product A at, for example, −18 ° C. Since the liquid product C introduced into the crusher 12 has a temperature of, for example, about 40 to 65 ° C., the liquid product C may serve to raise the temperature inside the crusher 12. The parts constituting the shredder 12 are generally made of stainless steel. Therefore, in the process of processing the low-temperature frozen product A, the temperature of the shredder 12 itself must be lowered to a very low temperature. When the shredder 12 itself becomes a low temperature, the operation of the parts may be more desirable than at room temperature. There is a problem that not only can not be made but also the life of the parts can be shortened. Therefore, by introducing a relatively hot liquid product (C) into the crusher 12, it is possible to prevent the temperature of the crusher 12 itself from lowering, which improves the operation of the crusher 12 and maintains its long life. Can provide an effect.

In addition, the liquid product C introduced into the crusher 12 may be partially dissolved in the crushed product B by being mixed with the crushed product B discharged from the crusher 12. As a result, the crushed product B is not merely a collection of crushed small grains, but can be in a semi-liquid state in which the small grains and the liquid are mixed. It is very difficult to transport small grains of solids in the tube-shaped transfer tube T1, but it can be provided that the transfer operation can be easily made in the semi-liquid state in which the liquid is mixed.

Specifically, the product circulation path 18 returns a portion of the liquid product to the crusher 12 downstream of the product flow path 142 of the tube jacket 14. In addition, the product circulation path 18 is provided with a control valve (19). The control valve 19 may be a valve for manually adjusting the ratio of the amount of product introduced into the product circulation path 18 among the liquid product C discharged from the product flow path 142. By operating the control valve 19 while observing the operation state of the shredder 12, the user returns a predetermined amount in the range of, for example, about 10 to 20% of the liquid product (C) discharged from the product flow path (142) It can be adjusted to be introduced into the crusher 12.

On the other hand, the hot water jacket 40, the hot water flow space 42 and the hot water flow space 42 into which the hot water discharged after changing the product from the crushed product (B) to the liquid product (C) in the tube jacket 14 It may be configured to include a hot water inlet 41 for introducing hot water into the hot water outlet 41 and the hot water outlet 43 for flowing hot water. The warm water flow space 42 may be formed over the entire outer surface of the crusher 12, or may be formed to contact at least a portion of the outer surface of the crusher 12. Preferably it may be arranged to heat-exchange the lower surface of the crusher 12. The hot water jacket 40 is a separate space from the space where the product is moved in the crusher 12, and thus the hot water flowing in the hot water jacket 40 is not mixed with the product.

On the other hand, in order to ensure that the hot water stays in the hot water jacket 40 is long, the hot water inlet 41 is disposed at the lower end of the hot water jacket 40 and the hot water outlet 43 is disposed at the top of the hot water jacket 40 It is preferable. In this case, since the hot water rises from the bottom of the hot water jacket 40 to fill the hot water flow space 42 and the hot water flows out of the top of the hot water jacket 40, the hot water filled in the hot water flow space 42 is a crusher ( The time of contact with the surface of 12) may be long.

Since the hot water supplied to the warm water jacket 40 is warm water at about 40 to 65 ° C., the hot water of the crusher 12 may serve to prevent the temperature of the crusher 12 from dropping below zero while processing the frozen product A. . In addition, the hot water jacket 40 is not disposed in the lower part of the shredder 12, that is, the portion into which the frozen product A is put, but in the area where the hot water jacket 40 exists as the shredded product B. The effect of partially dissolving and semi-liquid state by the heat from 40 can be obtained.

In the case 30 of the crusher 12 shown in FIGS. 5 and 6 according to the present invention, the hot water jacket 40 is in contact with the lower part of the case body 30a and the outer surface of the auxiliary portion 30b. It may be arranged in the form. Accordingly, the heat transferred to the crusher 12 side by the hot water flowing through the hot water jacket 40 may be transferred to the crushed product B, which temporarily stays in the auxiliary space 35 of the auxiliary part 30b, and the crushed product ( B) is partially warmed to dissolve.

During operation of the shredder 12, the frozen product A in the form of a solid mass is slid by gravity through the product inlet 31 formed in the upper half of the case 30, and is introduced into the shredder 20. The product crushed by the crushing knife 20, that is, the crushed product (B) is discharged to the auxiliary space (35) below through the product outlet 32 provided in the lower portion of the case body (30a) by gravity. The shredded product B temporarily staying in the auxiliary space 35 is mixed with the liquid product C supplied with heat from the hot water jacket 40 and / or introduced through the inlet 33 connected to the product circulation path 18. Can be. The liquid product C flows into the surface of the shredding knife 20 from the top of the case body 30a, flows down the surface of the shredding knife by gravity, and then falls into the auxiliary portion 30b. Therefore, the crushed product B in the auxiliary part 30b can be partially dissolved and / or mixed with the liquid product C, thereby becoming semi-liquid.

In the above description, the present invention has been described through specific embodiments, but various modifications may be made to those skilled in the art by referring to and combining various features described herein. Therefore, it should be pointed out that the scope of the present invention should not be limited to the described embodiments, but should be interpreted by the appended claims.
