Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for producing block frozen foods.
In this specification, the term frozen food is used to include all foods that can be solidified into lumps by cooling, such as frozen desserts such as ice cream candy and ice cream, and butter. It will be done.

Conventional technology and its problems For example, as an apparatus for producing lumpy tiyocolates in the form of flattened spheres, they are arranged horizontally without any gaps, and a plurality of recesses corresponding to each other are formed on the outer circumferential surface, and their adjacent locations (this In the specification, a close location refers to a location where a pair of die rolls are closest to each other or are in contact with each other. comprising die rolls and a filling device for filling the recesses of each die roll with thiokolate above the adjacent location of the pair of die rolls,
It is known that a die roll cooling fluid (brine) is supplied inside both die rolls. In the case of Chiyocolate, it contracts when cooled;
It becomes easy to fall off from the wall of the recess. For this reason, the tyokolate filled in the recesses of each die roll is joined together when the recesses pass through adjacent locations, and is easily removed from the recesses by gravity as the recesses move downwards from the adjacent locations and away from each other. to fall away. However, in the case of ice cream candy, when it is cooled, it tends to stick to the walls of the recess, so it is impossible to apply such a manufacturing device as is. In other words, in the case of the above-mentioned manufacturing equipment, the food is only filled into the recess to the extent that it is almost flush with the outer circumferential surface of the die roll, so when both recesses pass close to each other, the food may are not pressed together with strong force, but are joined with relatively weak force. In the case of ice cream candy, as mentioned above, it tends to stick to the walls of the recesses, so when the recesses pass close to each other, the ice candy molded in one piece will stick to the walls of the recesses of both die rolls. When the recesses move downward from their adjacent locations and separate from each other, the ice candy that was once joined may split into two again and remain in both recesses. Therefore, it is difficult to reliably form ice cream candy into a block using the above-mentioned manufacturing apparatus as is.

An object of the present invention is to solve the above problems and provide a manufacturing apparatus that can also be used for ice cream candy.

Means for Solving the Problems The apparatus for producing bulk frozen foods according to the present invention includes a pair of die rolls in which one or more of a pair of recesses corresponding to each other on the outer peripheral surface are rotated at the same speed; For filling, it has a sliding convex surface that is almost in contact with the outer peripheral surface of the recessed part above the adjacent part of the pair of die rolls, a groove that is a concave inside this sliding convex surface, and a filling hole that penetrates from the food supply means to the groove part. It consists of a plate and a suction plate that is provided with a suction hole that penetrates from the surplus food suction means to a position slightly below the lower end of the sliding convex surface.

Effect The food filled into the recesses of a pair of die rolls is
As the recesses pass through adjacent locations, they are joined together and formed into a block. At this time, the food filled in the recess is exposed to strong force against each other when the recess passes through the adjacent part because the part filled in the groove inside the sliding convex surface bulges outward from the outer peripheral surface of the die roll. They are pressed together to ensure that they are joined together. Moreover, the remaining food at this time is sucked out from the suction hole by the suction means and discharged.

Example: The drawing shows one of the manufacturing devices for spherical ice cream candy.
As an example, this device includes a pair of die rolls 10 and 11 arranged horizontally in large numbers without gaps, and a filling device 12 arranged above these adjacent parts.
It is equipped with

The two rolls 10 and 11 are hollow, and have a plurality of hemispherical recesses 1 corresponding to each other on their outer peripheral surfaces.
7 and 18 are formed at equal intervals in the circumferential direction. Note that the recesses 17 of each roll 10, 11,
The diameters of 18 are equal to each other. first roll 10
is fixed to a rotating shaft 19 connected to an appropriate drive device (not shown). The second roll 11 is
It is rotatably supported by a fixed shaft 20 parallel to the rotating shaft 19, and connected to the rotating shaft 19 by suitable means such as gears. The two rolls 10 and 11 have recesses 17 and 18 at adjacent locations.
They are rotated at a constant speed in the direction of the arrow shown in the figure so that their positions match and they move downward at the same speed.

Both ends of the first roll 10 are sealed by appropriate means, and a roll heating fluid 21 consisting of water hot enough to slightly melt the ice cream candy is continuously supplied to the inside of the roll 10. Note that as the roll heating fluid 21, in addition to hot water, a liquid such as heated oil or a gas such as heated air can also be used.

A plurality of rings 22 are fixed to a fixed shaft 20 inside the second roll 11, and a cylinder 23 parallel to the fixed shaft 20 is fixed to the outer periphery of these rings 22. This cylinder 23 is located slightly lower than the fixed shaft 20 toward the first roll 10, and a portion of the cylinder 23 protrudes slightly from the outer peripheral surface of the ring 22. The ring 22 and cylinder 23 constitute a kind of cam. However,
The ring 22 and the cylinder 23 are integrated, that is, the ring 2 has a cylindrical projection at the position of the cylinder 23.
2, and the cylinder 23 may be omitted. A plurality of guide holes 24 are formed at the bottom of each recess 18 of the second roll 11 and penetrate the peripheral wall of the roll 11 in the radial direction, and a rod 25 is fitted into each hole 24 so as to be freely slidable in the axial direction. ing. A head 25a having a larger diameter than the other parts is integrally formed at the inner end of each rod 25, and the end surface of the head 25a is formed into a spherical surface. Further, the outer end of each rod 25 is formed into a concave spherical surface that matches the shape of the bottom of the recess 18. Both ends of the second roll 11 are sealed by appropriate means, and the sealed space inside the roll 11 is connected to a vacuum pump (not shown). Then, by reducing the pressure inside the roll 11,
Each rod 25 is always drawn inward, and its head 25a is in contact with the outer peripheral surface of the ring 22 or cylinder 23. And the rod 25 is the ring 2
2, when the roll 1 is in contact with the recess 18
1 and its outer end coincides with the bottom of the recess 18 and contacts the cylinder 23, it projects from the bottom of the recess 18 into the recess 18.

The filling device 12 includes a plurality of filling plates 26 and suction plates 27. Filling plate 2
The suction plates 6 are placed above the rolls 10 and 11, and the suction plates 27 are stacked alternately in the axial direction of the rolls 10 and 11 so that they are located at both ends of the rolls 10 and 11, and are fixed integrally by appropriate means. Two rolls 10, 1 are placed at both ends of the lower part of the filling plate 26.
A sliding convex surface 26a having a shape that allows constant contact with 1.
and a groove 26b which is a recess inside the groove. Both lower side surfaces of the suction plate 27 are made wider than the filling plate 26 so as to completely cover the contact surface between the rolls 10, 11 and the sliding convex surface 26a. The lower end of the filling plate 26 reaches a little above the area adjacent to the two rolls 10 and 11. The width of this groove 26b is approximately equal to or slightly larger than the diameter of the recesses 17 and 18. A filling hole 29 is formed in the filling plate 26. The filling hole 29 extends downward from the center of the upper surface, branches into two, and opens at the middle of the groove 26b. In addition, suction holes 30 are provided in the portions on both sides of the filling plate 26 that reach from the top surface thereof to the upper portions of the grooves 26b.
is formed. The lower end of the suction plate 27 is longer than the lower end of the filling plate 26,
It reaches the same position as the vicinity of the rolls 10 and 11 or a little below it. Suction holes 31 are formed in the suction plate 27, extending downward from the center of its upper surface, extending in the axial direction of the rolls 10, 11 slightly below the lower end of the filling plate 26 and upward from the adjacent portion, and opening on both sides. ing. Although not shown, in the entire structure in which the rolls 10, 11 and a large number of suction plates 27 are stacked alternately, in the suction plates 27 at both ends, the lower ends of the suction holes 31 are on the side of the filling plate 26. It is open only on one side. Further, the upper end of the filling hole 29 is connected to an ice candy supply device, and the upper ends of the suction holes 30 and 31 are connected to an ice candy suction pump.

In the above manufacturing apparatus, ice candy A at, for example, -7 to -6° C. is continuously supplied from the ice candy supply device to each filling hole 29 of the filling device 12 . This ice candy A has filling hole 2.
The recesses 17 and 18 of each roll 10 and 11 that have been moved from the lower end opening of roll 9 to this portion are filled with the recesses 17 and 18 of each roll.
At this time, the air in the recesses 17 and 18 is discharged upward through the groove 26b of the filling plate 26, so that no air remains in the recesses 17 and 18. Also, since the rod 25 of the second roll 11 retracts from the bottom of the recess 18 into the inside of the roll 11 and contacts the ring 22, the ice candy A
is filled in the entire recess 18 in a hemispherical shape. Furthermore, the ice candy A is not only filled in the recesses 17 and 18, but also in the grooves 26b. In this way, the corresponding recess 1
The ice cream candy A filled in the tubes 7 and 18 is integrally molded into a spherical ice cream product B while the recesses 17 and 18 pass adjacent locations.
At this time, the ice candy A is in the recesses 17 and 18.
Since they are raised on the outside, they come into contact with each other with strong force and are completely joined together. Incidentally, when the ice candy A is integrated, the remaining ice candy A is sucked through the suction hole 31 of the suction plate 27 and discharged. Therefore, there is no possibility that fin-like projections or the like will be formed at the joint portion of product B due to excessive ice candy A. In addition, the remaining ice cream candy A is placed in the groove 2 of the filling plate 26.
Even if it moves to the top of 6b, the filling plate 2
Because it is sucked and discharged from the suction hole 30 of 6,
There is no possibility that the groove 26b becomes clogged and air cannot be removed. The first roll 10 is cooled by the ice candy A, but is heated by the heating fluid 21, which heats the portion of the ice candy A that is in contact with the wall of the recess 17. A is difficult to adhere to the wall of the recess 17. The product B therefore necessarily adheres to the walls of the recess 18 of the second roll 11. The type, flow rate, temperature, etc. of the roll heating fluid 21 are appropriately determined so that the product B is easily separated from the wall of the recess 17 and the roll 10 does not become too hot. Product B molded into a spherical shape
is attached to the wall of the recess 18 of the second roll 11,
As the roll 11 rotates, it moves downward. When the rod 25 hits the cylinder 23 and protrudes into the recess 18, the product B is pushed out of the recess 18 and falls due to gravity. In addition,
The second roll 11 is also cooled by the ice candy A, but if the temperature gets too low, it becomes difficult for the product B to separate, so a heater (not shown) is provided at an appropriate part to keep it at an appropriate temperature. There is.

The configurations of each part of the die rolls 10, 11 and the filling device 12, the means for discharging the product, etc. are not limited to those of the above embodiments, and can be modified as appropriate. for example,
The filling device 12 may be constructed entirely in one piece. The rod 25 may be moved forward and backward using fluid pressure, such as an air cylinder.
In addition, the product can be directly pushed into the recess 18 by pressure such as air.
It is also possible to discharge from

The product device according to the present invention can of course be applied to bulk frozen foods other than ice cream candy. Furthermore, the shape of the product is not limited to a spherical shape.

Effects of the Invention Since the apparatus for producing bulk frozen foods of the present invention has the above-described configuration, it can be applied to ice candy and other products, and can be used to produce ice cream candy filled in the recesses of a pair of die rolls. They can be brought into contact with each other with strong force and molded together reliably.
