Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a drying device for confectionery dough used in the production of hailstones, rice crackers, and other confectioneries.

(Prior art) Conventionally, in manufacturing rice crackers such as arare and kasu senbei, rice crackers dough is formed into a predetermined shape and dried using hot air, and then the inside of the dough is dried. It was left to rest so that the moisture content was even, then dried once again, and then subjected to final processing such as firing to become a finished product.

The second drying process is generally called "removal of foil".
In many cases, a confectionery dough drying apparatus was used, in which a cylindrical drum was rotatably installed and a heat source was attached to supply hot air from the center of the drum into the drum.

(Problems to be Solved by the Invention) The above confectionery dough drying device blows hot air into the drum through the inner wall of a cylindrical drum to dry the confectionery dough contained within the drum. However, the only way to change the amount of hot air passing through the drum is to adjust the amount of hot air, making it difficult to set the drying conditions for confectionery dough.

In addition, it was difficult to evenly pass the hot air through each part of the drum.
Drying conditions throughout the drum are not uniform,
As a result, there was a problem that the confectionery dough dried unevenly.

The inside of the drum is divided into a plurality of rooms along the radial direction, but the amount of ventilation is not uniform within each room, but also between rooms.

(Means for Solving the Problem) Therefore, this invention provides a ventilation window on the peripheral wall and side wall of the drum, adjusts the opening degree of the ventilation window,
This made it possible to adjust the amount of ventilation.

That is, this invention provides a confectionery dough drying apparatus in which a cylindrical drum is rotatably installed horizontally and a heat source is attached to supply hot air from the center of the drum into the drum. In the department,
An inner cylinder is installed, and the space between the inner wall of the drum and the outer wall of the inner cylinder is radially divided into a plurality of chambers, and each chamber has a rotatable disk having a small hole, and a circumferential wall having a small hole overlaps with the inner wall of the drum. This confectionery dough drying device is characterized by being equipped with a ventilation window and an opening/closing door.

The ventilation windows are provided on the end wall and the circumferential wall of the drum, respectively.

(Function) As with the conventional confectionery dough drying device, confectionery dough to be subjected to secondary drying is stored in a drum, and while the drum is rotating, hot air is supplied from the center of the drum to dry the confectionery dough. Dry the fabric.

The drying conditions can be adjusted by adjusting the opening degree of ventilation windows provided on the peripheral wall and end side wall of the drum, but comprehensive adjustment can be made in conjunction with adjustment of the amount of ventilation on the heat source side.

Furthermore, since there are a plurality of ventilation windows, it is possible to uniformly adjust the uneven drying conditions depending on the location within the drum by changing the degree of opening of each ventilation window.

(Example) An example of this invention will be described below with reference to the drawings.

Figure 1 shows the appearance of the device of the example.
A cylindrical drum 2 is rotatably installed on a pedestal 1 via rollers 3, 3, and is rotated on the rollers 3, 3 by a rotation drive mechanism (not shown) installed in the pedestal 1. It is becoming more and more common.

A breathable inner cylinder 4 made of a mesh plate, a punched metal plate, etc. is installed in the center of the drum 2, and a frame 1 is installed in one side of the cavity 5 inside the inner cylinder 4.
The tip of a blower duct 7 led from a heat source 6 provided on one side of the room is exposed. As shown in FIG. 2, the space between the drum 2 and the inner cylinder 4 is divided radially at equal intervals by partition walls 8, 8 to form a plurality of chambers 9, 9 in the circumferential direction. End side wall 1 of the drum 2
0 has ventilation windows 11, 11 corresponding to each room 9, 9.
In addition, opening/closing doors 13, 13 and ventilation windows 14, 14 are provided on the peripheral wall 12 of the drum 2, corresponding to the respective rooms 9, 2, respectively.

Although the ventilation windows 11 and 14 are different in size,
The structure is the same. Figures 3 and 4 show the surrounding wall 1.
2, a disc 15 is attached to the outside of the peripheral wall 12 by overlapping the disc 15, and the center hole 17 of the disc 15 is fitted into the bolt 16 planted in the peripheral wall 12, and the bolt 16 is fitted with a butterfly. A nut 18 is screwed on, and when the wing nut 18 is loosened, the disk 15 can rotate. The disk 15 has a small hole 1.
9 and 19 are bored in the peripheral wall 12, and small holes 20 and 2 corresponding to the small holes 19 and 19 are formed in the peripheral wall 12.
0 is bored, and the small holes 19 and 20 overlap each other depending on the rotational position of the disk 15, so that the extent of the opening can be changed.

The small holes 19, 20 may be long holes 21, 22 along an arc, as shown in FIG. It is also possible to change the degree of overlap of openings such as small holes or long holes by moving the sliding plate. In short, the structure described above is such that the opening area of the small hole etc. can be changed.

The confectionery dough drying apparatus of the above embodiment has a drum 2.
After opening the opening/closing door 13 provided on the peripheral wall 12 of the chamber 9 and putting rice cracker or other confectionery dough into the chamber 9 and closing the opening/closing door 13, the hot air from the heat source 6 is supplied to the drum 2 while rotating the drum 2. Drying work is carried out by blowing air into the inner cylinder 4 and sending it to each chamber 9, 9 through its side wall.

The amount of ventilation through the ventilation windows 11 and 14 provided in each room 9 and 9 can be adjusted by rotating the disk 15, so the amount of air blown on the heat source 6 side and the amount of ventilation inside the drum 2 can be adjusted to achieve the desired drying conditions. can be obtained. or,
For example, due to the amount of confectionery dough stored between the rooms 9 and 9 in the drum 2,
If the amount of ventilation is not uniform, or if the amount of ventilation is not uniform within each room 9 (for example, in the longitudinal direction of the drum 2), adjust the amount of ventilation of the ventilation windows 11 and 14 individually to improve the overall airflow. Uniform drying conditions can be achieved.

(Effects of the invention) According to this invention, the amount of ventilation through the ventilation window of the drying device can be adjusted, so it is possible to easily set the desired drying conditions by adjusting the amount of hot air blown and the amount of ventilation through the ventilation window. There is an effect that can be achieved.

In addition, since there are multiple ventilation windows and the amount of ventilation can be adjusted individually, the drying conditions inside the drum can be uniformized.
This has the effect of producing homogeneous products.
