Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for producing a center-containing oily food in which a center made of a solid is covered with a layer made of an oily food such as chocolate, and an apparatus used therefor.
[0002]
[Prior art]
Conventionally, as chocolate confectionery, many chocolate confectionery, such as nuts, almonds, jelly, and the like, which are covered with a chocolate layer around the center, are on the market.
[0003]
Such a solid chocolate cake containing a center is mainly manufactured by one of the following two manufacturing methods.
[0004]
The first manufacturing method is a method that uses a revolving device to roll a solid product that becomes a center product such as nuts and almonds, and melts the chocolate around it to form a coating layer by gradually cooling it. Since it can be manufactured with simple equipment, it is widely used.
[0005]
In the second manufacturing method, molten chocolate is filled into a resin mold, then a solid center product is added, and the molten chocolate is further filled and cooled and solidified together with the mold. Is a method of die cutting.
[0006]
[Problems to be solved by the invention]
However, in the first manufacturing method, since the chocolate is coated while rotating a center product such as a nut, the overall shape is limited to a substantially spherical shape, and there is a problem that a visually innovative product cannot be obtained. In addition, there is a problem that the individual dimensions are not easily uniform and poor in appearance.
[0007]
In addition, according to the second manufacturing method, it can be formed into a desired shape and size, but it requires equipment such as transport, cooling, and reheating of individual molds. There is a problem that the cost becomes high.
[0008]
On the other hand, a method using a continuous molding apparatus as shown in FIG. 9 is conventionally known as a method for obtaining a chocolate molded article made only of chocolate dough, although it does not obtain a chocolate cake containing a center.
[0009]
In FIG. 9, reference numerals 1 and 2 denote a pair of two rollers each having a surface on which a large number of concave molds 3a and 3b are formed, arranged side by side in the state of being close to each other. It is designed to rotate at. The inside of each of the rollers 1 and 2 is hollow, and a refrigerant is introduced into this portion so that the surfaces of the rollers 1 and 2 are cooled to -20 to -15 ° C.
[0010]
A chocolate molded product can be continuously obtained by rotating the rollers 1 and 2 while continuously supplying the molten chocolate 4 between the rollers 1 and 2 so as to accumulate a certain level. That is, the molten chocolate 4 supplied between the rollers 1 and 2 is filled in the concave molds 3a and 3b of the left and right rollers 1 and 2, and cooled and solidified in the concave molds 3a and 3b, while the left and right concave molds are filled. It moves to the proximity part of 3a, 3b. Then, the left and right concave molds 3a and 3b are abutted against each other, and are molded and solidified in a granular form along the inner shape thereof, and the concave molds 3a and 3b are separated from the left and right again as the rollers 1 and 2 are rotated. The product 4a falls downward. 5 is a belt conveyor for conveying the molded product 4a to the next cooling step.
[0011]
In addition, since the said molded product 4a is a continuous string shape, it separates | divides individually by appropriate methods, such as applying to a rotating drum, and becomes a granular molded product.
[0012]
According to this manufacturing method, the equipment is small, and there is an advantage that a molded product having a certain size can be easily mass-produced.
[0013]
Therefore, the inventors of the present invention manufacture a chocolate confectionery with a center by putting a solid center product into the concave mold 3a (3b) of one roller 1 (or 2) in advance in the above method. However, in this case, the center product is exposed from the chocolate dough, or it is detached from the concave mold 3a (3b) during the rotation of the rollers 1 and 2, causing a defective product, It was found that a good molded product could not be obtained and was not practical.
[0014]
In addition, it is conceivable to put the center product in the concave mold 3a (3b) in a state where the center product is previously coated with a fixing binder (molten chocolate or the like). There is a problem that it is not easy and is complicated in terms of equipment. Moreover, even if it can be added, the binder may be exposed from the surface of the molded product with a boundary line, resulting in a poor-looking appearance.
[0015]
The present invention has been made in view of such circumstances. Regardless of the shape of the center product, the external appearance is good, the center product is securely in the center, and a molded product of a certain size is continuously obtained. It is an object of the present invention to provide a process for producing a fat-containing food with a center and a device used therefor.
[0016]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention has two pairs of rollers, each having a plurality of concave molds formed on the surface and provided with cooling means for cooling the surface from the inside, in a state of being close to each other.

Preliminary filling means 14 including a body 11, a supply pipe 12 for supplying the molten chocolate 4 to the cylindrical body 11, and a molten chocolate tank 13 serving as a supply source is provided. Reference numeral 15 denotes a pump.
[0026]
As shown in FIG. 2, the cylindrical body 11 is set so that the opening covers three concave molds 3 b formed on the surface of the roller 2 in the circumferential direction and covers the entire row in the width direction. In the rectangular cylinder, the opening edge is close to the surface of the roller 2. The lower end edge 16 of the side wall 11a of the cylindrical body 11 on the side where the concave mold 3b enters is formed to be thick with a circular cross section, and an arcuate taper is formed on the inner surface 16a. This is intended to improve the sealing performance of this portion with respect to the surface of the roller 2 and to prevent any trouble in the rotation operation of the roller 2. Further, the side wall 11b of the cylindrical body 11 on the side where the concave mold 3b exits has a lower portion 17 which is sharpened in an edge shape, and surplus from the surface of the concave mold 3b preliminarily filled with the molten chocolate 4 The molten chocolate 4 is sent out while being scraped.
[0027]
The inner surface of the cylindrical body 11 is set to have an appropriate temperature on the inner surface of each side wall by temperature adjusting means (not shown). By the way, in this example, the inner surface of the side wall 11b is set to 40 to 45 ° C., and the other inner surface is set to 28 to 32 ° C. This is so that the tempering does not collapse while the molten chocolate 4 is accumulated in the cylinder 11, and it can be reseeded during the scraping operation of the excess molten chocolate 4 by the lower edge of the side wall 11b. Is.
[0028]
Further, between the position where the cylinder 11 is provided and the molten chocolate reservoir 10 (returning to FIG. 1), the inside of the concave mold 3 b preliminarily filled with the molten chocolate 4 via the cylinder 11 is provided. Further, a center product input means 20 for supplying a center product made of a solid material is provided.
[0029]
As shown in FIG. 2, the center product loading means 20 includes a center product loading hopper 22 formed in a loading port 21 whose upper portion is open and whose lower portion can be opened and closed downward by a spring force, and in the center product loading hopper 22. The center product 23 supplied to the center product 23 is pushed in from the top to the bottom, and the center product 23 that is gradually conveyed from the center product supply device 25 (see FIG. 1, but this diagram is schematically) The roller 2 can be poured into the concave mold 3b on the surface of the roller 2 from above in the vertical direction. The push rod 24 is attached to appropriate lifting means (not shown) such as a cylinder.
[0030]
As shown in FIG. 3, the center product supply device 25 has a recess 26 for positioning and holding the center product 23 at the same interval as the interval in the width direction of the recessed molds 3 a and 3 b formed on the rollers 1 and 2. As shown by the arrow B, the elongated bars 27 are intermittently conveyed by the conveying means 28 in a state of being arranged in a line. This feeding operation is synchronized with the rotation operation of the rollers 1 and 2, and the center product 23 corresponding to one row of the concave mold 3b arranged in the roller width direction is the center product input hopper (hereinafter abbreviated as "hopper"). The inside of the hopper 22 is pushed into the concave mold 3b by the push-out rod 24. In addition, in order to correct | amend the attitude | position of the supplied center goods 23 appropriately, the hopper 22 is lightly given with the vibration apparatus 29 which consists of a crank mechanism.
[0031]
Further, the bar 27 is subjected to light vibrations to the left and right in the feed direction by the vibration device 30 having the same configuration as the vibration device 29 for the hopper 22 during the conveyance. That is, the center product 23 is supplied from the tray 31 or the like onto the bar 27 at any time, but the supplied center product 23 is randomly generated in a rectangular frame-shaped fixed frame 32 that is freely attached to the transport surface. Scattered around. Then, by the vibration of the bar 27, the center products 23 are held in the recesses 26 formed in the bar 27 at predetermined intervals one by one, and the excess items are blocked and sent to the next. It enters into the recess 26 of the bar 27. In this way, the center product 23 is conveyed and supplied above the hopper 22 while being positioned and held at an appropriate interval.
[0032]
Note that if the center product 23 is supplied once and distributed into the recesses 26 only by vibration, the recesses 26 may be emptied. In this example, two fixed frames 32 are provided and repeated twice. The center product 23 is supplied to give vibration.
[0033]
Further, as shown in FIG. 4, the bar 27 shifted to the left and right due to the vibration operation returns to an appropriate position by passing the position correction guide 33 provided on the downstream side thereof.
[0034]
Using the above apparatus, for example, a chocolate cake containing a center can be manufactured as follows. In this example, almonds are used as the center product 23. Then, the concave molds 3a and 3b on the surfaces of the rollers 1 and 2 (returning to FIG. 1) were formed in a semi-rugby ball shape having a major axis of 30 mm, a minor axis of 15 mm, and a depth of 6 mm. Further, the surface temperature of the rollers 1 and 2 was set to be −20 to −15 ° C., and the rotational speed of the rollers 1 and 2 was set to a peripheral speed of 400 mm / min.
[0035]
Based on the above condition setting, first, the molten chocolate 4 is accumulated at a certain level between the rollers 1 and 2 to form the molten chocolate reservoir 10, and the cylinder 11 is rotated while rotating the rollers 1 and 2 in the direction of arrow A. Then, the molten chocolate 4 (for preliminary filling) is supplied from the tank 13, and the molten chocolate 4 is filled into the concave mold 3 b of the roller 2 from the cylinder 11. This state is shown in FIG.
[0036]
And while passing through the part which the lower end opening of the said cylinder 11 contact | abutted, and coming to the position located just under the hopper 22 of the center goods injection | throwing-in means 20, the said filled molten chocolate 4 is a concave shape. It solidifies into a shell shape according to the inner shape of the mold 3b. This state is shown in FIG. Reference numeral 40 denotes a portion solidified in a shell shape.
[0037]
Next, the center product 23 is put into the concave mold 3 b that has been pre-filled from the hopper 22 of the center product putting means 20 by the push-in rod 24. As shown in FIG. 6A, the charged center product 23 is surrounded by unsolidified molten chocolate 4 and enters the molten chocolate pool portion 10 while the periphery is cooled and solidified.
[0038]
Then, in close proximity to the concave mold 3a of the roller 1 in which the molten chocolate 4 has been sufficiently taken in, which has been rotated from the opposite side, both solidified portions 40 are united, and the rugby ball is centered around the center product 23. A solidified layer having a shape is formed, and further solidification proceeds inward. This state is shown in FIG. Then, as the concave molds 3a and 3b of the rollers 1 and 2 move away, the molded product 4a formed into a hard rugby ball shape is almost completely cooled and solidified, and falls downward by its own weight. . And it is conveyed by the belt conveyor 5 to the following cooling process. In addition, since the molded product 4a is normally connected like a conventional case (see FIG. 9) and is continuously connected in a string shape, the molded product 4a is individually separated and commercialized in the next step. In this way, the chocolate cake containing the center can be obtained continuously.
[0039]
According to the above manufacturing method, the center product 23 is not exposed, and the molded product 4a having a uniform dimension can be obtained continuously. Even if the center product 23 is not only spherical but of any shape, a good molded product 4a can be obtained. Furthermore, by performing preliminary filling and center product input with both rollers 1 and 2, respectively, chocolate confections having a more complicated configuration can be easily mass-produced.
[0040]
In the above example, it is preferable that the amount of the pre-filled molten chocolate 4 is at least an amount that completely covers the inner surface of the concave mold 3b. That is, when the amount of the molten chocolate 4 is small and the inner surface of the concave mold 3b is only partially covered as shown in FIG. 7A, the solidified portion 40 formed by cooling is shown in FIG. As shown in FIG. 2, it becomes partial in the concave mold 3 b. When the center product 23 is inserted in this state, as shown in FIG. 8A, the unsolidified molten chocolate 4 pushed away by the center product 23 comes into contact with the inner surface of the concave mold 3b and solidifies first. Solidify separately from the portion 40. At this time, since the melted chocolate 4 is highly viscous, it cannot sufficiently enter the boundary with the solidified portion 40 and solidifies with the gap S remaining between them. For this reason, on the surface of the obtained molded product 4a, as shown in FIG. 8 (b), a concave line 50 enters between the portion 40 solidified first and the portion 40 'solidified later, and the appearance is good. It ’s not good. In particular, when the surface of the chocolate is coated with sugar, the step of the recessed line 50 appears clearly, which is not preferable.
[0041]
Further, in the above example, the cylinder 11 and the like whose inner surface can be temperature-adjusted are provided as the preliminary filling means 14, but the preliminary filling into each concave mold 3b (3a) is not limited to the above configuration, Any configuration can be used as long as the molten chocolate 4 can be filled.
[0042]
Further, the center product input means 20 and the center product supply device 25 for supplying the center product 23 to the center product input means 20 are not limited to the above example, and can be set to appropriate configurations. However, it is necessary to put the center product 23 in an appropriately positioned state in accordance with the arrangement of the concave molds 3a and 3b of the rollers 1 and 2, and for that purpose, the configuration as described above is used. Is preferred.
[0043]
The pre-filling means 14 and the center product input means 20 are arranged so that the pre-filled molten chocolate 4 is not completely solidified and the center product 23 is charged in an unsolidified state. Is set. Further, the arrangement of the center product input means 20 and the molten chocolate reservoir 10 is not particularly limited.
[0044]
And in the said Example, although it was made to obtain the chocolate cake containing a center using the melted chocolate 4 as an oily food material for outer periphery layer formation and using an almond as the center goods 23 in the center containing oily food, already described As described above, the types of the oleaginous food and the center product 23 are not limited to this, and appropriate types can be selected. Further, by pre-filling different molten fat and oily ingredients with the left and right rollers 1 and 2 or by feeding different center products 23 with the left and right rollers 1 and 2, respectively, for example, two chocolate layers and two centers are provided. It is possible to easily mass-produce complex centered oil-based foods that are of various types.
[0045]
【The invention's effect】
As described above, according to the process for producing a fat-containing food with a center according to the present invention, with a small-scale facility, the center product is reliably filled in the center and is not exposed to the surface. With continuous dimensions, it can be produced continuously. And it has the advantage that it can shape | mold whatever center goods are not only spherical but what kind of shape. Furthermore, by carrying out pre-filling and center product input with both rollers, there is also an advantage that the oil-containing food with a more complicated structure can be easily mass-produced.
[0046]
Moreover, according to the manufacturing apparatus of the centered oil-based foodstuff of this invention, the said manufacturing method can be simply implemented only by adding improvement to a conventional apparatus, and can suppress equipment cost low.
