Multilayer ice strip manufacturing method

The invention relates to a method for manufacturing a multi-layered ice strip, in particular to a method for manufacturing a multi-layered ice strip without using a positioning piece or a positioning convex ring.

The double round popsicles (commonly known as Japanese ice), plum blossom popsicles, or paulownia popsicles that are common in sightseeing spots are cut from a double layer of ice. Two different methods of manufacturing the double-layered ice strip are disclosed in Taiwan, I287436 and I296920, respectively.

Taiwan I287436 patent discloses a method for manufacturing an oblate two-color popsicle, which is to ensure that the core of the round bar-shaped popsicle formed by the first material and the first molding die is positioned on the second molding die, and the bottom is positioned. a second forming die of the convex ring. The method mainly involves first aligning the solidified poplar core and inserting it into the positioning convex ring at the bottom of the second molding die, and then pouring the second raw material into the second molding die. However, this causes several problems. First, the production of the core of the popsicle is bound to have errors. The core of the popsicle with too large diameter cannot be placed in the positioning convex ring to locate. The core of the popsicle with too small diameter will have a gap between the positioning convex ring and the core of the popsicle and cannot achieve the function of supporting and fixing. Causes the core of the popsicle to be easily dumped. Secondly, if the positioning convex ring is too long, the subsequent extraction of the two-color popsicle embryo material will not be easily extracted due to the combination of the positioning convex ring and the solidification of the popsicle core. Conversely, if the positioning convex ring is too short, the supporting action will be If the difference is poor and the supporting effect is poor, the subsequent pouring of the second raw material may cause the core of the popsicle to be dumped and skewed due to the flow of the second raw material. Third, the location of the locating collar is deep (located at the bottom of the second layer of cartridge), and the popper core is not easily aligned to it, resulting in a longer and less efficient time required to insert the popper core into the second forming dies. The foregoing problems eventually lead to a long process time of the two-color popsicle embryo material, waste of manpower, and an increase in equipment cost due to the need to make a positioning collar.

In addition, Taiwan I296920 discloses the positioning of the first type of ice material formed by solidification of the first cartridge by the positioning piece. However, each of the first and second cartridges requires a positioning piece, which is costly. Moreover, when using the positioning pieces, each positioning piece needs to be embedded in each of the first layer magazine and the second layer box, and is used for extracting each of the double layer ice materials. The plungers need to pass through the corresponding perforations in the center of each positioning piece, which is very time consuming. The foregoing problems eventually lead to a long process time of the double-layered ice material, waste of manpower, and an increase in equipment cost due to the need to fabricate the positioning piece.

A first main object of the present invention is to provide a method for producing a multi-layered ice strip, which is particularly characterized by the use of a solid work associated with the solidification process of an outer layer of ice material for positioning, which solves the above-mentioned conventional method because of the necessity of using a positioning collar or The problem of long process time, wasted manpower and high equipment cost caused by the positioning piece.

Specifically, the method of the present invention fills a liquid inner layer of ice material into a plurality of cuvettes of an inner layer ice mold. The inner layer ice mold which has been filled with the inner layer ice material is placed in a cooling bath, and the plurality of tanks of the inner layer ice mold are immersed in a cooling liquid of the cooling tank. Before the inner layer of ice material solidifies, a popsicle is inserted into the inner layer of ice material of each tank. After the inner layer of ice material in each of the inner ice molds is condensed into one of the solid inner icicles, the inner icicles are used to form the inner icicles from the inner icing Take out in the slot. The liquid outer layer of ice material is filled into a plurality of cuvettes of an outer ice mold. The outer ice mold that has been filled with the outer layer of ice material is placed in the cooling bath, and the plurality of tanks of the outer ice mold are immersed in the cooling liquid of the cooling bath. After the bottom of the outer layer of ice in each of the outer ice molds is solidified to form a thin ice layer, the inner layer icicles are correspondingly inserted into the plurality of pockets of the outer ice mold. The bottom surfaces of the inner icicles are brought into contact and fixed to the thin ice layer in the corresponding pockets in the outer ice mold. After the outer layer of ice in each of the outer ice molds is completely condensed into one of the solid layers of ice, the plurality of ice strips are taken out from the plurality of ice molds of the outer ice mold by the ice stick .

Since the inner layer of icicles is inserted into the liquid material of the outer layer of ice material, as long as the inner layer of icicles is inserted into the bottom and the thin ice layer which is formed at the bottom of the crust of the outer layer of ice is frozen, the inner layer of ice is formed. Coagulation occurs between the bottom surface of the column and the thin ice layer, thereby causing the inner icicle Fixed on the thin ice layer, so that the inner icicle is not easy to pour after insertion, and the inner icicle is directly inserted, which takes a very short time, and the insertion process does not need to locate the convex ring or the positioning piece or the like. The structure is assisted, so the equipment cost is low.

Referring to the first figure, a perspective view of an inner ice mold used in a preferred embodiment of the method of the present invention. An inner ice mold 10 is a receptacle 11 having a plurality of upwardly facing openings 14 for filling an inner layer of ice material, respectively. The inner layer ice mold 10 has a platform 12 connecting the pockets 11 and the grips 13. Grips 13 are located on either side of the platform 12 for lifting the inner ice mold 10.

The pocket 11 of the present embodiment is shaped like a cylinder, but can be set according to the appearance of the multilayer ice strip to be formed, for example, geometric shape, plum shape, star shape, apple shape, and the like. Here and below, ice products having two or more different ice materials are collectively referred to as multi-layered ice bars.

Referring to Figures 2(a)-(e), a flow chart of a preferred embodiment of the inner layer of ice material of the multi-layered ice strip of the present invention is illustrated below.

First, as shown in the second diagram (a), the liquid material of an inner layer of ice material 15 is filled into the tank 11 of the inner layer ice mold 10. The inner layer of ice material can be a pure milk drink such as milk or goat milk or a milk drink with added flavor.

Then, as shown in the second diagram (b), the inner layer ice mold 10 filled with the inner layer ice material 15 is placed in the cooling bath 16 in which the cooling liquid 17 is placed, and the plurality of inner tank ice molds 10 are accommodated. 11 is immersed in the cooling liquid 17 of the cooling bath 16 to lower the temperature of the inner layer of ice material 15 and solidify.

As shown in the second figure (c), before the inner layer of ice material 15 is solidified, it is preferably semi-condensed. The solid state (refers to the solid ice layer having a considerable thickness on the periphery and still in an unfrozen liquid state near the center), and a popsicle 30 is inserted into the inner layer of ice material 15. If only the outer periphery is frozen into an ice layer when the popsicle 30 is inserted and unplugged (the ice layer is frozen and formed on the columnar inner side wall of the cavity 11), the ice extracting stick 30 is inserted obliquely outward from the center to make the end of the popsicle 30 Insert obliquely into the ice layer. If only the central small extent remains unfrozen when the popsicle 30 is inserted and unplugged, the popsicle 30 is directly inserted into the central small extent (the diameter of which is slightly larger than the outer diameter of the popsicle 30).

As shown in the second diagram (d), after the inner layer of ice material 15 is condensed into a solid inner layer icicle 15a, the inner layer ice mold 10 is placed in the thawing tank 18 in which the thawing liquid 19 is placed. The thawing liquid 19 is optionally water-containing, and the surface of the inner layer icicle 15a which is in contact with the inner wall of the tank 11 is slightly melted by water.

As shown in the second diagram (e), the inner layer icicle 15a is taken out from the pocket 11 of the inner layer ice mold 10 by the ice extracting stick 30. Thus, the inner icicle 15a in the multi-layered ice strip is completed. After the plurality of inner layer icicles 15a are manufactured according to the above method, they can be stored in the refrigerator for use. Then, the inner icicles 15a can be utilized to perform the processes described below.

Referring to the third drawing, a perspective view of an outer ice mold used in a preferred embodiment of the method of the present invention. An outer ice mold 20 is a receptacle 21 having a plurality of upwardly facing openings 24 for filling an outer layer of ice. The outer ice mold 20 has a platform 22 that connects the plurality of slots 21 and the grip 23. Grips 23 are located on either side of the platform 22 for lifting the outer ice mold 20.

Referring to Figures 4(a)-(e), a flow chart of a preferred embodiment of the outer layer of ice material of the multi-layered ice strip of the present invention is illustrated below.

The cuvette 21 of the present embodiment is shaped like a cylinder, but can be set according to the appearance of the multi-layered ice strip to be formed, for example, geometric shape, plum shape, star shape, apple shape, and the like.

First, as shown in the fourth figure (a), the liquid material of an outer layer of ice material 25 is filled into the cavity 21 of the outer layer ice mold 20, wherein the groove 21 of the outer layer ice mold 20 is larger than the inner layer of solidification. Icicle 15a. The outer layer of ice material may be flavored milk, for example: strawberry flavored milk, taro flavored milk, almond milk, peanut flavored milk, mango flavored milk, etc., the taste is different from the taste of the inner layer of ice, providing a double taste of the consumer.

Then, as shown in the fourth diagram (b), the outer layer ice mold 20 filled with the outer layer ice material 25 is placed in the cooling tank 16 in which the coolant 17 is placed, and the plurality of tanks 21 of the outer layer ice mold 20 are formed. The coolant 17 immersed in the cooling bath 16 lowers the temperature of the outer layer of ice 25 and solidifies.

As shown in the fourth figure (c), before the outer layer of ice material 25 has not completely solidified, it will be The plurality of inner icicles 15a formed by solidification of the inner layer of ice material are inserted one-to-one into the outer layer of ice 25 in the plurality of cavities 21 of the outer layer of ice mold 20, and each inner layer of icicles 15a One of the bottom portions 150 directly contacts the thin ice layer 250 that has been formed at the bottom of each of the corresponding pockets 21 in the outer layer ice mold 20 (see the schematic view of the fifth figure and its description).

As shown in the fourth figure (d), the outer layer of ice is all condensed on the periphery of the inner icicles. After collectively forming one of the solid layers of the ice strip 31, the outer layer ice mold 20 is placed in the defrosting tank 18 in which the thawing solution 19 is placed. The surface of the multi-layered ice strip 31 which is in contact with the inner wall of the container 21 is slightly melted by water.

As shown in the fourth diagram (e), the plurality of layers in the solidified state are utilized by the ice extracting stick 30. The ice bars 31 are taken out from the plurality of cavities 21 of the outer ice mold 20.

Finally, the popsicles 30 on the plurality of multi-layered ice strips 31 are withdrawn, that is, The production of a multi-layered ice strip 31 of double-layered ice material.

The temperature of the above cooling liquid 17 is preferably equal to or lower than minus 18 degrees, preferably Between 20 and 25 degrees below zero, so that the formed multi-layered ice strips are not too soft or too hard, too soft or too hard will affect the taste, and too soft and easy to dissolve, too hard then the ice chopsticks that will be held or When the popsicle is inserted into the multi-layered ice strip, it is difficult to insert, and the cutter for subsequent ice cutting is easily damaged and it is difficult to cut.

Referring to FIG. 5, a partial cross-sectional enlarged view of the receptacle 21 of the fourth diagram (c) shows the bottom section of one of the pockets 21 of the outer ice mold 20 of the present invention and its internal condition. The bottom section is located in the ice cream liquid 17, and the bottom surface of the bottom section (i.e., the bottom surface of the tank 21) is the fastest suction speed relative to the other positions of the tank 21. Therefore, after the outer ice mold 20 shown in the fourth figure (b) is placed in the cooling groove 16, the portion of the outer ice material 25 in contact with the bottom surface is quickly frozen to form a thin thin ice layer 250. . Since the thin ice layer 250 is frozen on the bottom surface of the cavity 21, in the fourth figure (c), the inner layer icicle 15a formed by solidification of the inner layer of ice material is in contact with the bottom layer. The ice layer 250 is immediately frozen with the thin ice layer 250. That is, the bottom surface 150 of the inner layer icicle 15a is adhered or fixed to the thin ice layer 250 by freezing, so that after the inner layer icicle 15a is inserted into the bottom to contact the thin ice layer 250, Easy to dump. In addition, since the outer layer of ice material is formulated to be more viscous than the inner layer of ice material, the viscous outer layer of ice material also provides a certain degree of assisting support, so that the probability of the inner layer of icicles 15a being dumped is greatly reduced. Moreover, the inner icicle 15a is directly inserted, which takes a very short time, and the insertion process does not require positioning of the convex ring. Or the assistance of the positioning piece or similar structure, so the equipment cost is low.

Of course, the above-mentioned multi-layered ice strip (actually a double-layered ice strip) of the present invention can be further formed into a third layer or more of other ice materials by the above steps, and the process is similar to the above, and will not be described again.

It is worth noting that when other ice materials of the third layer and above are formed, the type of the ice material is only required to be different from the outermost ice material of the multi-layered ice strip which has been solidified. For example, the third layer of ice material is different from the second layer (outer layer) of ice material, but is not limited to the same type as the first layer (inner layer); the fourth layer of ice type and the third layer of ice The type of material is different, but is not limited to the same type of ice material as the second layer and the first layer.

In summary, when the invention is industrially usable and progressive, and there is no similar product in the same product or published and novel, it has met the application requirements of the invention patent.
