Apparatus for Crushing and Thawing of Frozen Product Having Assembled Cutter}

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 a large amount of frozen product automatically and continuously to provide a liquid product in a subsequent product process, as well as the shredding knife of the crusher in a manner in which multiple blades are assembled. The present invention relates to a frozen product shredding thawing apparatus having a new assembly type shredding knife which can be easily maintained, reduced in cost, and further extended in component life.

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.

A product that is changed into a state, 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 is changed from the frozen product A in the solid state to the crushed product B in the form of small grains or mixed with liquid while passing through the crusher 12, and further proceeds to the tube jacket 14. As it passes through, it changes 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.

Here, the crusher 12 is a device which makes the crushed product B by crushing by crushing the product in the form of a solid mass, that is, the frozen product A. 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 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.

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.

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, the shredding knife 20 of this shredder 12 is a cylindrical member that rotates to shred the product P.

5 and 6, the shredding knife 20 is configured by assembling a plurality of disk bodies 23 having a constant width (W) on one rotating shaft 21. The width W of the disc body 23, that is, the size of the rotary shaft 21 in the longitudinal direction is much shorter than the length of the rotary shaft 21, and in the example shown in FIG. 6, eight disc bodies 23 are rotated. It is assembled to 21.

At least one blade 25 is assembled to each of the disc bodies 23. Each blade 25 has a width W equal to the width W of the disc body 23, as illustrated in FIG. 8, and has a constant thickness H and a length L. The blade 25 has an assembly portion 251 and a blade portion 253. In the assembling unit 251, a bolt insertion hole 250 is formed as a hole having a long groove shape. The blade portion 253 protrudes from the generally flat assembly portion 251 of length L1 to have two inclined surfaces D1 and D2 having lengths L2 and L3 and is sharply tapered toward the end.

The bolt insertion hole 250 has a long long diameter LH in the length L direction of the blade 25 and a short short diameter in the width W direction of the blade 25.
