Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method of placing granular solids such as nuts or candy in the cavities formed between the upper and lower dough sheets of baked confectionery such as biscuits, snacks, and rice crackers. The present invention relates to a method and apparatus for producing hollow baked confectionery containing granules.

[Conventional technology]

Conventionally, hollow baked confectionery, in which particulate matter is housed in a cavity formed by two upper and lower sheets of dough, has been developed due to the novelty of the presence of particulate matter in the cavity and the fact that the two upper and lower sheets of roasted dough and the particulate matter are The resulting complexity of flavor, as well as the mobility of the particulates within the cavity, was highly appealing to consumers.

This hollow baked confectionery containing granules is made by rolling and forming two upper and lower sheets of highly sticky dough such as biscuits, snacks, and rice crackers, and arranging granules such as nuts and candy fruits on the lower sheet-like dough. After placing another sheet-like dough on top of the sheet, the peripheral edge is pressed and cut into an appropriate shape, and then baked in an oven.

[Problems to be Solved by the Invention] However, in the conventional manufacturing method, when a large number of granules are placed on the lower sheet-like fabric, if the granules have a shape close to a spherical shape such as a nut, It often rolled on the fabric and moved out of the predetermined position by the time another sheet-like fabric was placed above it. It is obvious that particles displaced from a predetermined position will be crushed by the press or cut by the cutting blade in the peripheral edge press, cutting, and molding steps that are performed later, causing problems.

Therefore, unless a method is devised to correctly arrange the granules at predetermined positions, it is impossible to efficiently produce large quantities of the desired hollow baked confectionery.

[Means for solving problems]

As a result of intensive studies to solve the above-mentioned problems, the present inventors created a recess by vacuum suctioning the position where the granular material should be placed in the lower sheet-like fabric, and deposited the granular material in the formed recess. The inventors have discovered that hollow baked confectionery in which the particulate matter is properly housed in the center can be continuously mass-produced by supplying the same, and based on this knowledge, the present invention has been completed.

That is, first, the present invention transports sheet-like dough such as rice crackers, snacks, etc. on a slat conveyor made of a slat plate with a large number of through openings, and the upper edge slides against the lower surface of the slat plate. The material reaches a vacuum chamber installed below the slat conveyor, and by reducing the pressure in the vacuum chamber, the sheet fabric is pulled to form a large number of depressions. A method for producing a hollow baked confectionery containing particulates, which comprises supplying particulates to a part, then placing another sheet-like dough on top of the sheet-like dough, and then cutting and forming the dough while pressing the peripheral edge thereof, Second, a slat conveyor consisting of a large number of slat plates provided with a large number of through openings at regular intervals in the transfer direction and the transverse direction thereof is arranged in an endless ring shape or in an intermittent moving manner, and the slat conveyor is A decompression chamber is installed so that its upper edge is in sliding contact with the lower surface of the slat plate, and
A first pair of rolling rolls, a granular material supply device, a second pair of rolling rolls, and a sheet-like dough compression cutting and forming device are arranged in sequence above the slat conveyor in the direction of conveyance. The present invention relates to an apparatus for manufacturing hollow baked confectionery containing granules.

The present invention will be described in detail below based on illustrated representative embodiments.

A sheet-like dough 2 for rice crackers, snacks, etc., which has been rolled and formed by a first pair of rolling rolls 1, is placed on a slat plate 3.

As shown in Figure 2, the slat conveyor is
A large number of slat plates 3 are fixed to the moving chain 5 at fixed parts 6 and are arranged in an endless ring or intermittently movable manner. The slat plate 3 is provided with a through opening 4 at a predetermined position, and when the slat plate 3 on which the sheet-like fabric 2 is placed is transferred to the upper part of the decompression chamber 7 by the slat conveyor, the suction fan 8 is operated. to reduce pressure. When the pressure inside the vacuum chamber is reduced, the sheet-like fabric on the slat plate is pushed by atmospheric pressure, and since the fabric has appropriate extensibility, a recess 1 is formed at the through-opening 4 of the slat plate.
0 is formed. The depth of this recess varies depending on factors such as the degree of pressure reduction, the diameter of the through opening, and the properties and thickness of the sheet material. Since the concave portion 10 is intended to improve the fixing arrangement of particulate matter, for example, when the diameter of the through opening 4 is 15 mm, the depth is required to be 2.5 mm or more, and excessive depressurization may cause the concave portion If the depth is too large, problems such as tearing of the fabric will occur, so the upper limit is about 9 mm. The optimum depth of the recess is determined by the conditions for stably fixing the particulate matter (3 mm) and the degree of vacuum 12 mmHg (at this time, depth 6 mm) that can be achieved with a simple pressure reducing device.

When the thickness of the fabric is within the normal range of 0.5 to 1.5 mm, the thickness of the fabric has almost no effect on the depth of the recess, and when the through opening diameter is 15 mm and the normal vacuum level is 5 to 18 mmHg (preferably 6 to 6 mmHg). 12 mmHg), a recess with a depth of 2.5 to 9 mm, preferably 3 to 6 mm is obtained. FIG. 3 shows these relationships. As is clear from the figure, a concave portion having a depth almost comparable to the normal vacuum level can be obtained in the range of the normal vacuum level of 5 to 18 mmHg.

After the recesses are formed in the sheet-like material, granules 12 are fed into the recesses 10 by a granular solid supply device 11 that is operated in synchronization with the position of the through-opening of the slat plate.

Thereafter, a sheet-like dough (usually having a thickness of 0.5 to 1.5 mm) is rolled by a second pair of rolling rolls 13.
mm) 14 are continuously fed onto the lower sheet-like fabric 2 and placed in a superposed manner. As a result, the granules are sandwiched between the two sheet-like fabrics, and are fixed and placed in precise positions.

Next, the crimping/cutting device 15 is lowered to press the peripheral edge of the sheet-like fabric into an appropriate shape, and cut and shape it. The molded product is transferred to an oven using a conveyor such as a steel conveyor, and baked there to obtain the intended hollow baked confectionery containing granules. Note that 9 in the figure is a conduit connecting the decompression chamber and the suction fan.

〔Effect of the invention〕

The present invention provides an apparatus for manufacturing hollow baked confectionery products in which granular materials such as nuts and candy are uniformly contained in the hollow space of the hollow baked confectionery. Confectionery can be produced continuously in large quantities.
Moreover, unlike conventional products, the resulting product has granules placed in precise positions, and no trouble occurs when two dough sheets are polymerized, their peripheral edges are crimped, and cut and formed.
