Description

[Detailed Description of the Invention] (a) Technical Field of the Invention This invention provides a method for forming a lower coagulated layer that is already filled in a pack with a food liquid that forms two upper coagulated layers of a multi-layer packed coagulated food. This invention relates to a stuffing device for multi-layer stuffed coagulated food that is accommodated on top of a food liquid.

(Ex) Conventional technology and problems Recently, in packed coagulated foods, the main food (pudding or tofu) and the side food (honeycomb or bean paste) are layered in multiple layers in the same pack, such as pudding with two pieces of honey or tofu with bean paste. In order to pack such coagulated foods, first fill the pack with a predetermined amount of the main food liquid or secondary food liquid, and after this has stabilized horizontally. A secondary food liquid or a main food liquid forming the upper coagulated layer is filled, and then a lid is attached.

In this case, coagulated foods are generally packed in transparent packs so that the contents can be seen from the outside, so it is important to store the food so that the boundaries between each food layer are clearly defined to prevent visual deterioration of taste. However, since all the contents packed into the pack are stored in a liquid state, when filling the food liquid that forms the upper coagulation layer, the food liquid is already filled. If the food liquid is mixed with the food liquid in the lower coagulated layer, which is stabilized by the liquid, and the food liquids are mixed with each other at the boundary between the lower food liquid and the upper food liquid, the food liquids should be filled so that a clear boundary line appears. This was extremely difficult and naturally led to a decline in product prices.

In particular, when the difference in specific gravity of the contents (tofu and bean paste) to be accommodated is relatively small, such as in case of tofu with bean paste, the food liquid (bean paste or tofu) that forms the upper coagulated layer forms the lower coagulated layer. When it is mixed into a food liquid (tofu or bean paste), it has not been possible to solve the above problem because the natural separation effect does not take place even if it is allowed to stand still for a predetermined period of time until it solidifies. (c)
Purpose of the Invention The present invention has been devised in view of the above circumstances, and it is possible to prevent the multi-layered coagulated food from being filled in advance, regardless of the magnitude of the difference in specific gravity of each coagulated layer of the multi-layered coagulated food stored in a container. It is an object of the present invention to provide an apparatus capable of filling and storing a food liquid forming an upper coagulated layer on top of a food liquid forming a lower coagulated layer without mixing the food liquid forming an upper coagulated layer.

(d) Structure of the invention In order to achieve this object, the present invention has an enlarged space at the discharge end of the liquid feeding tube that is much larger than the inner diameter of the liquid feeding tube, and an opening at the lower end. A cavity nozzle is installed, and the cavity nozzle has a flow velocity reduction surface formed on its wall so that at least one of the side walls is inclined toward the opening, and the food liquid from the discharge end collides with the cavity nozzle. At the same time, the lower part has a slight gap between the soil surface and the opening, and is equipped with a fluid guiding flat plate that is horizontal to the installation surface.

(E) Embodiments of the Invention Hereinafter, embodiments in which the present invention is applied to an apparatus for stuffing tofu with bean paste will be described with reference to FIGS. 1 and 2.

The stuffing device 1 shown here includes a transparent resin bag 2 with
This is for filling a predetermined amount of liquid bean paste 3 that forms the lower coagulated layer using a stuffing device (not shown) and stabilizes it in a horizontal state, and then fills it with soybean milk that forms the upper coagulated layer.

The soymilk is normally stored in a storage tank similar to a known stuffing device, and is supplied via a liquid feed pipe 4 connected to this storage tank. The above bag 2 stops at the position for a certain period of time.
During the stoppage time, a predetermined amount is measured and supplied by a measuring device. A box-shaped hollow nozzle 6 having an inverted trapezoidal longitudinal cross section is installed and fixed at the discharge end 5 of the liquid sending pipe 4, and both inclined walls 7 and 8 on the longitudinal side thereof are relative to the nozzle center 0. In order to collide the soymilk that is arranged symmetrically and fall from the discharge end 5 to reduce its speed,
Its inclination angle 0 is set to 45 degrees. Further, the lower ends of both inclined walls 7, 8 face each other with a slight interval, and the lower ends of the other side walls 9, 10 form an opening that faces the discharge end 5 and is narrower than the inner diameter of the discharge end 5. 11 is formed. still,
The liquid feeding pipe 4, which is installed perpendicularly to the installation surface of the stuffing device 1, is located at the nozzle center 0 of the hollow nozzle 6. Reference numeral 12 denotes a guide plane plate having a U-shaped cross section and arranged perpendicularly to the nozzle center 0 with a slight interval between it and the opening 11, and vertical flanges 1 erected on both sides of the guide plate in the longitudinal direction.
3 and 14 are welded and fixed to the inner walls of the side walls 9 and 10, and attached to the cavity nozzle 6.

Note that when the guide plane plate 12 is located at the upper part of the bag 2 as shown in the figure, the guide plane plate 12 is located at both longitudinal ends and the inner wall 15 of the bag 2.
The size is such that a certain gap G, G'' is formed between the
The soymilk 16 sent from the storage tank to the liquid feeding pipe 4 flows into the hollow nozzle 6 through the discharge end 5, and then is led out from the opening 11 onto the guide plane plate 12, and is directly transferred to the guide plane plate 1.
2 flows in both left and right directions in the longitudinal direction while being guided by vertical flanges 13 and 14, and is transmitted from each end through gaps G and G'' to the inner wall 15 of bag 2 and onto the liquid filling 3 that has already been filled. It will flow into.

In the process until the soymilk 16 is filled from the liquid feeding pipe 4 into the bag 2, the soymilk 16 is first depressurized when flowing into the cavity nozzle 6 from the discharge end 5 of the liquid feeding pipe 4, and Among the soymilk 16, the soymilk A, Kuchi, and C that have flowed around the circumference of the liquid feeding pipe 4 collide with the inclined walls 7 and 8 when they fall, and their speed is reduced and killed. Soy milk two is
When the soymilk 16 collides with the inclined wall and bounces back, it simultaneously collides with the upper surface of the guide plane plate 12 and its speed is reduced, and when these soymilk 16 flows on the guide plane plate 12, Since the water flows in the form of a film, the speed is reduced. Therefore, the stuffing device 1 of this embodiment
The soymilk 16 filled into the bag 2 is sufficiently reduced in pressure and speed, and is accommodated by sliding on the upper surface of the liquid bean paste 3 in the lower coagulated layer that has already been filled. This prevents them from mixing with each other, and it is possible to obtain a coagulated food product in which the boundary line 17 between the liquid bean paste 3 and the soybean milk 16 is clearly visible, as shown in FIG.

In addition, as a result of manufacturing and experimenting with various structures, the structure of this embodiment was found to be the simplest structure and yet able to obtain the above-mentioned effects. It has the additional effect of being easy to clean and disinfect after use and convenient for maintenance.

FIG. 4 shows another embodiment. In this stuffing device 1", an inclined wall 7" on one side is formed in the same manner as in the above embodiment, and an inclined wall 8" on the other side is formed vertically without inclining the whole. It has a structure in which only a part of the wall, that is, the part facing the lower end of the inclined wall 7'' is inclined, and the liquid feeding pipe 4'' is positioned perpendicular to the inclined wall 7''. According to the above, soymilk 16'' flowing into the cavity nozzle 6'' from the discharge end 5'' of the liquid feeding pipe 4'' is depressurized and at the same time collides with the inclined wall 7'', its speed is reduced and killed, and then it collides with the inclined wall 8''. It has the same effects as the first embodiment, such as speed reduction.

(f) Effects of the Invention As described above, according to the present invention, the food liquid discharged from the discharge end of the liquid supply pipe is reduced in pressure and velocity, flows into the bag, and coagulates in the lower part of the bag that has already been filled. Since it is accommodated so as to slide over the food liquid forming the layer, it is not mixed into the food liquid forming the lower coagulated layer, and is filled so that a clear boundary line appears.

For this reason, there is no visual deterioration of taste,
There is a practical benefit in preventing a decline in product prices.
