Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bread dough mixer for mixing bread dough prepared by kneading wheat flour, water, yeast, sugar and the like, and more specifically 800 kg to 1 in a bread manufacturing factory for producing a large amount of bread and the like. The present invention relates to a dough mixer for mixing a large amount of material of about a ton.

[0002]

Bread dough is usually made by kneading raw materials such as flour, water, yeast and sugar. And at a bakery factory that manufactures a large amount of bread etc., 800 kg
A special bread dough mixer is used to mix a large amount of material of about 1 ton.

As shown in FIGS. 4 to 6 showing the prior art, a bread dough mixer is provided with a stainless steel ball body 1 on the inner peripheral side and a cooling gas consisting of a plurality of stages of jacket plates 20 on the outer peripheral side. The passage 2 is provided, and the outer wall plate 3 is provided with a gap 4 on the outer peripheral side of the jacket plate 20 forming the cooling gas passage 2. The bread dough mixer is provided with a bread dough entrance / exit 10 on one side of the ball body 1, and the three rotating bars 13 opened 120 degrees as agitators are rotated around a horizontal rotating shaft 12 to allow the bread dough to move inside the ball body 1. Mix the dough. The shape of the bread dough mixer is, as shown in FIGS. 1, 4 and 5, a modified front cross-sectional shape. The inner peripheral surface of the ball body from the side wall surface to the lower wall surface that is struck toward
It is formed as 1. Further, the cooling gas passage 2 for cooling the heat generated from the bread dough is provided on the outer peripheral surface side of the curved inner surface portion 11 from the side wall surface to the lower wall surface.

The cooling gas passage 2 is provided from the lower cooling gas inlet 21 to the upper cooling gas outlet 22 in order to cool the heat generated from the bread dough during mixing. The cooling gas passage 2 is provided with a passage including a plurality of stages of jacket plates 20 in the horizontal direction on the curved outer surface side,
Since one end of each is connected to the upper or lower passage, the cooling gas passage 2 becomes a single continuous passage, and the cooling gas flows in a zigzag manner through the cooling gas passage 2 from the bottom to the top. (Prior Art 1, FIG. 4 and Prior Art 2,
(See FIG. 5).

The ball body 1 is formed of a metal such as stainless steel having good heat conductivity, and the thickness thereof is desired to be thin in order to quickly conduct the temperature of the cooling gas flowing on the outer peripheral side of the ball body 1. The thickness of the bread dough of 800 kg to 1 ton mixed by the rotary bar 13 is required to withstand the impact and is conventionally 10 mm.

FIG. 5 and FIG. 6 show the prior art 2, in which one vertical reinforcing member 6 is provided in the vertical direction at the widthwise central portion on the outer peripheral side of the jacket plate 20 forming the cooling gas passage 2. The plate 20 was pressed down. Although not shown, a configuration has also been known in which a plurality of vertical reinforcing members 6 are similarly provided in the vertical direction from the outer peripheral side of the jacket plate 20 for reinforcement. The vertical reinforcing member 6 is provided with upper and lower mounting plate-shaped bodies 60, and is mounted on the upper and lower portions of the jacket plate 20 by welding or the like. The reinforcing plate 61 is vertically mounted on the upper and lower mounting plate-shaped bodies 60. Was erected. At this time, the outer end portion of the reinforcing plate 61 has a gap with the inner peripheral surface of the outer wall plate 3 and is not fixed.

[0007]

The bread dough mixer, however, rotates a heavy dough of 800 kg to 1 ton and rotates the heavy dough from the inner side of the curved inner surface portion 11 from the side wall surface to the lower wall surface of the ball body 1. The bread dough is struck every rotation, so it keeps receiving a very strong impact. Furthermore, there is a temperature difference between the high temperature applied to the inner peripheral surface of the rotating ball body 1 and the low temperature applied to the outer peripheral surface in contact with the cooling gas due to the mixing and heat generation of the bread dough, and the strong impact force repeatedly applied to these bread dough mixers. Another problem is that the welding of the jacket plate 20 is easily broken due to the influence of the temperature difference between high temperature and low temperature.

Further, as in the prior art 2, the jacket plate 2
Even if one vertical reinforcing member 6 or three to five vertical reinforcing members 6 are provided on the outer peripheral side of 0, the upper and lower mounting plate members 6 of the vertical reinforcing member 6
No. 0 had a problem that it was easily peeled off from the outer peripheral surface of the welded jacket plate 20.

At the same time, the cooling gas is inserted into the cooling gas passage 2 from the cooling gas inlet 21, and the cooling gas is sent to the cooling gas outlet 22 at the upper part while moving back and forth in a zigzag in the horizontal direction. This cooling gas causes the ball body 1 to
It is cooled from the outside.

During mixing, the collected dough is dropped onto the curved inner surface portion 11 of the ball body 1 from above to give an impact. This impact is transmitted to the jacket plate 20 of the cooling gas passage 2 and the outer wall plate 3 to which the outer end portion of the horizontal reinforcing plate 5 standing on the outer surface side of the jacket plate 20 is welded and fixed.
However, this impact is fixed by welding a plurality of horizontal reinforcing plates 5 to the outer wall plate 3, and the left and right end portions of the horizontal reinforcing plate 5 are also welded and fixed to the ball ends 15 and 15. The structure is firmly supported, and the impact on the welded part due to repeated impacts and temperature changes is mitigated, and early damage can be prevented.
