Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for dispersing powder and granules onto the surface of confectionery dough, etc.
This invention relates to a method of dispersing other powdery materials uniformly and without waste on the surface of confectionery dough, etc.

Note that confectionery dough, etc. here refers to not only unheated confectionery dough, which is generally referred to as confectionery dough, but also food dough that has been heated to some extent, and food dough whose main ingredients are seafood and meat, and includes powder and granular materials. generally refers to powder, granules, or flakes that are scattered on the surface of confectionery or food dough.

BACKGROUND OF THE INVENTION Conventionally, sliced almonds, sesame seeds, etc. have been sprinkled on the surface of sweets such as manjiyu, kutsky, and senbei to suit the tastes of consumers. Although confectionery is weighed mechanically, the spraying is usually done manually, making this process extremely complicated and problematic from a food hygiene perspective.

For example, manjiyu, kutsuki, senbei, etc. can be easily mass-produced by heating and baking or vaporizing them while continuously moving them through a moving zone. However, in order to spread powder and granules onto the surface of confectionery dough, a manual spreading process is required during this continuous heating process, which greatly impedes productivity. Therefore, the scattering process is usually carried out after baking or steaming the confectionery, and the manually dispersed powder and granules are not heated, which is extremely unsanitary.

Furthermore, powdery substances such as sliced almonds and sesame seeds have cohesive properties by themselves, and at the same time, some powdery substances, such as apricots and grapes, have sticky surfaces and form lumps in some parts. Therefore, it is extremely difficult to spray it onto the confectionery dough in quantitative amounts or individually separated.

From this point of view, the present inventor previously proposed a quantitative feeding device for powder and granular materials as described in Japanese Patent Publication No. 1045/1983. Confectionery dough is continuously supplied at intervals on a track (not shown), and a storage container 1 is disposed on this endless track, and a powder or granular material 3 such as sliced almonds is stored in the container. do. This container 1 is made of rubber or other elastic material,
The cross-sectional shape of the bottom portion is configured such that at least a portion or the entire portion thereof is arcuate.

A plurality of hammer members 2a...2n are arranged so that vibrations are intermittently applied to the bottom of the storage container 1 from the outside. The hammer members 2a...2n approach the bottom of the storage container 1 from the outer surface and strike the bottom of the storage container 1, applying the required vibration to the storage container 1, and this vibration causes the powder and granular material 3 to be crushed. The surface level is made uniform by smoothing and smoothing.

Further, a hopper (not shown) is provided close to the container 1, and a suction tube 4 is provided between the hopper and the container 1. Each of these adsorption cylinders 4 adsorbs a predetermined amount of powder and granular materials 3 from inside the storage container 1, transfers them to a hopper, and transfers the powder and granular materials to the surface of the confectionery dough on an endless moving trajectory via the hopper. be scattered.

In this quantitative feeding device, at least a part of the bottom surface of the container 1 is configured in an arc shape and is made of rubber or other elastic material, so that vibrations from each hammer member 2a...2n are transmitted to the container 1. It spreads evenly over the whole part, and the internal powder particles 3 receive appropriate vibrations, so that they are not pressed at all and can be constantly adsorbed and supplied without excess or deficiency.

However, the supply device of this configuration was originally developed mainly for the individual supply of powder and granules, and there remain problems such as collection of excess powder and granules during dispersion onto the surface of confectionery dough.

The present invention has been established based on the above-mentioned points, and specifically, it is possible to uniformly scatter powder and granules on the surface of confectionery dough, etc., and to effectively recover excess powder and granules that have been scattered. We propose a method for dispersing powder and granular materials.

That is, the method of the present invention sprays powder and granules onto the surface of confectionery dough, etc. on a moving band that moves continuously or intermittently, and then, on the downstream side of the confectionery dough, etc., the powder is sprayed onto the moving band from the downstream side to the upstream side. The present invention is characterized in that while a reverse airflow directed toward is caused to flow along the moving zone, this reverse airflow is sucked onto confectionery dough or the like to collect excess powder lumps.

Hereinafter, the method of the present invention will be specifically explained with reference to the drawings.

In addition, FIG. 2 is a side view of an example of an apparatus for carrying out the method of the present invention, FIG. Figures a and b are a perspective view and a cross-sectional view of an example of a powder and granular material recovery device.

First, in FIG. 2, the reference numeral 10 generally indicates a moving band with an endless track, and a baking plate is usually attached to this moving band 10, but the moving band 10 itself is made of a steel band plate, and rollers 11a at both ends are used. , 11b, and the moving band 10 runs continuously or intermittently. A squeezing machine 12 for supplying confectionery dough, etc. is arranged upstream of the moving band 10, and this squeezing machine 12 drips confectionery dough 13 (see FIG. 3) onto the moving band 10 in a desired shape. . Further, a powder and granular material dispersion device 14 and a powder and granular material recovery device are sequentially disposed downstream from the squeezing machine 12, and the confectionery dough 13 that has passed through these devices has a powder and granular material 16 on the surface as described later. The dispersed material enters a tunnel-type heating furnace 17, where it is fired or vaporized, and then discharged via a transfer conveyor 18 on the downstream side. It should be noted that although the transfer conveyor 18 is normally arranged substantially perpendicular to the moving band 10, it can be arranged in any direction as desired.

In addition, as described above, the spraying device 1 is placed on the confectionery dough 13.
When dispersing the powder and granular material 16 from 4, the powder and granular material 1
6 uses air energy to individually loosen the dough, and at the same time sprays it on the surface of the confectionery dough 13 in that state. By spraying in this manner, even if the particles of the powder or granular material have coagulation or stickiness, they are broken apart and uniformly scattered on the surface of the confectionery dough 13, and can be adhered in this state.

That is, as shown in FIG.
It consists of c. The spreading device 14 spreads the movable zone 1 by, for example, air or a cylinder (not shown).
It is configured to be able to move back and forth parallel to 0. Therefore,
When the moving band 10 is configured to move continuously in the direction of the arrow, the spreading device 14 moves following the movement of the moving band 10. Further, the spraying device 14 is configured to be able to rise and fall freely by, for example, a crank mechanism (not shown), and as the spraying device 14 moves along the trajectory 1, the speed vector A → B → C →
When the spreading device 14 moves as shown in FIG. Moving. In addition, in the case of a moving zone that is moved intermittently, it is sufficient that the spraying device 14 is configured to be able to move up and down.

In this dispersion device 14, an air introduction pipe 14d is attached to the enclosure 14c, and air is blown from the introduction pipe 14d. The introduction pipe 14d is installed with a downward slope as shown in FIG. 3, and the air 19 is injected downward with a downward slope. Hopper 14d of this kind of air
The powder and granular material 16 falling from the confectionery dough 13 is loosened by the energy of the blown air and falls, so that the powder and granular material 16 uniformly adheres to the surface of the confectionery dough 13. In addition, at this time, there is excess powder and granular material 16 around the confectionery dough 13.
remain, but these are collected by the recovery device 15 as described later.
Since it is completely recovered, there is no problem at all. Also,
At least the bottom portion of the hopper 14a is made of rubber or other elastic material, similar to the container 1 shown in FIG. 1, and can be configured to apply a predetermined vibration to the hopper 14d. With this configuration, the powder or granules can be directly loosened in the hopper 14d and uniformly dropped into the enclosure 14c without using a feeding device as shown in FIG. 1.

Next, confectionery dough 1 with powder particles sprinkled on the surface
3 is a reverse airflow 20 that advances with the moving band 10 and is directed from the downstream side to the upstream side in the recovery device 15.
(See FIG. 4b) is caused to flow, and the excess powder 16 around the confectionery dough 13 can be collected by suction by this reverse airflow.

That is, the recovery device 15 is composed of an air blowout device 21 and an air suction device 22 as shown in FIG. 4a.
1 is placed on the lower grain side. The blowout device 21 can be configured in any way as long as it can blow out air across the width direction of the moving band 10, but it is usually configured as a communication duct 21a.
The communication duct 21a is arranged in the width direction of the moving belt 1, with at least one injection port 21b inclined downward in the longitudinal direction (see FIG. 4b). Further, the suction device 22 can be constructed of any device as long as it can suck the reverse airflow 20 from the injection tube 21b across the width direction of the moving band 10, but normally, like the ejection device 21, the communication duct 22a is used. It is configured with a suction port provided in the longitudinal direction. The communication duct 22a is formed into a tube shape as shown in FIG.
is preferably constructed as a long hole. In addition, regardless of the structure of the suction port 22b, a pair of sidewall plates 22c and 22d are attached around the suction port 22b,
It is preferable that these jamb plates 22c and 22d be bent into an ampoule shape.

When the recovery device is configured in this way, the ejection device 2
The air jetted from 1 creates a reverse airflow 20 directed toward the upstream side.
flows on the surface of the moving zone 10, and this reverse airflow 2
0 is aspirated from the suction device 22. Therefore, even if the powdery material 16 is scattered around the confectionery dough 13,
This excess powder and granular material 16 is agitated by the reverse airflow 20 and can be sucked into the suction device 22 and recovered.

Note that if the communication duct 22a of the suction device 22 is configured to be tapered, the particles 16 can be collected on average across the width direction of the moving band 10, and a pair of cutting boards may not necessarily be provided around the suction port 22b. Good recovery can be achieved by providing at least one cutting board 22c.

As explained in detail above, the present invention sprays powder and granules onto the surface of confectionery dough, etc. on a moving band that moves continuously or intermittently, and then uses a reverse airflow directed from the downstream side to the upstream side to remove excess powder and granules. It can be uniformly spread over the surface of confectionery dough, etc., and can be mass-produced with ease of continuous and mechanization.
