JP2929205B2 - Automatic application method of ball coating liquid to hemisphere of confectionery - Google Patents

Description

The present invention relates to a hemispherical surface of confectionery, for example, Japanese and Western baked goods, bread, pie, etc. Baked or dried after application of confectionery to improve the gloss and baking color of the applied portion).

2. Description of the Related Art Conventionally, when a coating surface of a coating liquid in a confectionery (hereinafter, simply referred to as a confectionery) is flat, as shown in FIGS. A method in which a brush 32 is provided so as to reciprocate between two containers 31a and 31b, a confectionery 30 is placed between the containers 31a and 31b, and the brush 32 is applied by reciprocating, or FIG. As shown in (a) and (b), there is known a method in which a single nozzle 41 is used to spray and apply a coating liquid to a confectionery 42. However, there is no method for automatically applying the coating liquid to the hemispherical surface of the confectionery, and it is performed manually by brush.

Problems to be Solved by the Invention The method of automatically applying a coating liquid to the above-described flat coating surface, which is conventionally known, is applied to a hemispherical surface of a confection as it is. However, there is a disadvantage that it is not possible to uniformly coat the boundary portion with the non-applied portion, and in the method using the nozzle 41, the coating cannot be sufficiently applied to the boundary portion with the non-applied portion. If you increase the spray amount to prevent this,
There is an inconvenience that the coating liquid is excessively applied to the central portion of the coating portion, and a large portion becomes sagged.

In the conventional method of applying the coating liquid on the flat coating surface, the method using the first brush 32 is long regardless of whether the shape of the coating surface is flat or hemispherical. If the coating operation is continued for a long time, the coating liquid adhering to the brush 32 solidifies, so that there is a disadvantage that the brush 32 needs to be replaced at regular intervals, and the method using the second nozzle 41 requires a spray angle. If it is not widened, it cannot be applied uniformly, and there is a disadvantage that much of the coating liquid is wasted.

For this reason, conventionally, as described above, the application of the coating liquid to the hemispherical surface of the confectionery is currently performed manually by brush.

However, in the case of this manual operation, the quality of the applied state is greatly affected by the skill of the operator, and when the coating technique is inexperienced, if the liquid amount is too large, sagging occurs, but the liquid amount is too small. If the viscosity of the coating liquid is not appropriate, sagging or coating unevenness will occur, and defective products that cannot be marketed frequently occur.

For this reason, conventionally, there has been a demand for the development of a method for automatically and uniformly applying a coating liquid to a hemispherical surface of a confectionery. The present invention has been developed to meet this need.

Means for Solving the Problems The present invention has a viscosity of 400 to 1200 cps from a plurality of directions toward the center of the hemisphere of the confectionery, preferably from a symmetric direction.
And spraying the coating liquid at least once in the same direction, changing the direction, so that a predetermined portion of the hemispherical surface inside the final coating portion, preferably about 70% of the final coating portion, After applying the coating liquid to the area, air is applied from at least four directions toward the center of the hemisphere (this air may include not only pure air but also other substances such as a small amount of coating liquid. ) Is sprayed to spread and spread the coating liquid so as to uniformly apply the final coating portion of the hemisphere. The above viscosity range was set based on experiments, and it was confirmed that if the viscosity was out of this range, the viscosity was too drastic or, conversely, did not spread smoothly.

By spraying the coating ball liquid at least twice while changing the direction of action, it is possible to apply the liquid uniformly to a predetermined portion in the center of the hemisphere, and by adjusting the viscosity to 400 to 1200 cps, it is possible to obtain an appropriate flow. By spraying air from four directions or more, the applied coating liquid can be spread out and uniformly applied to the final application portion of the hemisphere.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.

1 (a), 1 (b) and 1 (c) are plan views for explaining the working steps of the present invention, and FIGS. 2 (a) (b) (c).
Is a side view of the same.

First, as a first step, as shown in FIGS. 1 (a) and 2 (a), the confectionery 1 is provided at a position facing each other toward the center of the hemisphere 2 to be coated with the coating liquid L. From the nozzles 3a and 3c, a coating liquid L having a viscosity of about 800 cps was applied at 4 kg / c.
sprayed in m ² pressure of about. The nozzles 3a, 3b, 3c, 3
Four ds are arranged at equal intervals toward the center of the hemisphere 2.

Next, as a second step, as shown in FIGS. 1 (b) and 2 (b), by changing the direction by 90 degrees, the coating liquid L is sprayed from the nozzles 3b and 3d in the same manner, and the hemispherical surface is sprayed. The coating liquid L is applied to a portion of about 70% of the target application portion in the central portion of No. 2. In this manner, by spraying the coating ball liquid L twice while changing the direction, the size and height of the diameter of the hemisphere 2 in the confectionery 1 may vary, or each nozzle 3
Even if the arrangement positions with respect to a, 3b, 3c, and 3d are slightly shifted, uniform application can be achieved.

Then, as a third step, as shown in FIGS. 1 (c) and 2 (c), each nozzle is moved toward the center of the hemisphere 2.
By spraying air or air A containing a small amount of coating liquid at a pressure of about 4 kg / cm ² from four directions equally spaced by 3a, 3b, 3c and 3d, the coating ball on the hemispherical surface 2 is sprayed. The liquid L is spread to the final application portion and uniformly applied.

The amount of the coating liquid to be sprayed varies depending on the area of the hemisphere, but the total amount is about 1 to 2 g.

Thus, the confectionery 1 in which the coating liquid L is uniformly applied to the hemisphere 2 is baked and completed.

In the first and second steps, the coating liquid L
An attempt was made to perform spraying from one direction instead of the direction and changing the direction a plurality of times. However, this method could not uniformly apply the coating liquid L. Further, in the third step, if the spray direction of the air A containing air or a small amount of the coating liquid is three or less, the coating liquid L could not be uniformly applied.

The present invention is not limited to the embodiments described above,
For example, the viscosity of the coating liquid L may be in the range of 400 to 1200 cps, and this viscosity changes under environmental conditions such as room temperature. Is large, the spray amount and the spray pressure may be increased. In adjusting the viscosity of the coating liquid L, it is not necessary to consider the state of the hemisphere 2, for example, the inclined state and the degree of surface roughness. In the above-described first and second steps, the coating liquid L may be sprayed simultaneously from three or more directions. May be sprayed.

Effect As is apparent from the above description, according to the present invention, since the coating operation of the coating liquid on the hemisphere of the confection can be performed automatically and uniformly, the coating liquid which has conventionally relied on manual work There is an effect that the application efficiency can be improved by automating the application operation.
