(Imaginary line 143) is substantially circular. The stirring blade 114 is rotated by a stirring drive motor 144 attached to the outer surface of the gantry 110.
[0022]
As shown in FIG. 2, the scraper 116 has a plurality of resin scraping members 162 attached to almost the entire circumference of a ring-shaped scraper frame member 160. The scraping member 162 rotates in contact with the inner surface of the bottom of the cooling tub 112 to scrape the cooked flake material attached to the inner surface of the bottom.

[0024]
As shown in FIG. 3, in the screw pump 134, a screw member 174 driven by a screw motor 192 is disposed in a horizontally extending discharge pipe 190. An inlet end 195 of the discharge pipe 190 communicates with a discharge hole 130 provided at the center of the bottom of the cooling tank 114. The outlet end 196 of the discharge pipe 190 communicates with the belt flaker 14 via the transport pipe 30.
[0025]
Operation of Cooling Device In the cooling device 14, during the cooling operation, the stirring blade 114 and the scraper 116 continue to rotate, and the temperature of the flake material in the central region of the cooling tank 112 is measured by the temperature sensor 150.
In preparation for charging the heated flake material into the cooling tank 112, cooling water at a first temperature, for example, 60 ° C. is supplied to the first jacket 120 and the third jacket 136, and a second temperature, for example, 10 ° C. to 15 ° C., is supplied to the second jacket 128. Supply cooling water at ℃. The flake material is charged and cooled while stirring, and the temperature of the flake material in the central region of the cooling tank 112 is measured by the temperature sensor 150. When the temperature sensor 150 detects the first temperature of 60 ° C., the cooling water of 60 ° C. is supplied to the second jacket 128. When the temperature sensor 150 stably detects the first temperature of 60 ° C., it is determined that the cooling of the flake material has been completed, and the flake material is discharged from the cooling device 14.
[0026]
The operating mechanism is such that when the melting point of the fat contained in the fat-containing material is, for example, 50 ° C., the cooling water of 60 ° C. (first temperature) higher than this is supplied to the first jacket 120 and the third jacket 136. During the cooling process, even if the flake raw material hits the upper part of the side wall of the cooling tank 112, the fat or oil is melted by the heating of the first jacket 120, and the raw material flows down from the side wall and does not adhere. In addition, the heating of the third jacket 120 prevents the raw material from sticking to a narrow space or the like of the discharge unit. During this time, the flake material at, for example, the initial 100 ° C. is gradually cooled by the cooling action of the second jacket 128. When the flake material has been cooled to approximately the first temperature of 60 ° C., cooling water of 60 ° C. is also supplied to the second jacket 128 to heat the surface of the cooling device 14 that is in contact with the flake material. As a result, the flake material does not adhere to the cooling device 14, maintains fluidity, and is smoothly discharged from the cooling device 14.
[0027]
Configuration of Belt Flaker As shown in FIG. 1, the belt flaker is prepared by cooling cooked flake raw material that has been cooled to a predetermined temperature by a cooling device 14 and is in a ragged shape, that is, a semi-milled state or a paste shape. The sheet is conveyed while being sandwiched between an upper cooling belt 201 and a lower cooling belt 202 arranged vertically. The cooked flake raw material is further cooled to be in a state of being stuck to the lower cooling belt 202 thinly. At a position where the conveyance by the cooling belt 200 is completed, the lower cooling belt 202 is wound around the pulley 204 to be deformed, and the cooked flake material which is thinned and adhered is separated from the lower cooling belt 202. Upon peeling, the cooked flake material breaks into small pieces.
[0028]
When a double belt flaker is used, the cooling action of the upper cooling belt 201 and the lower cooling belt 202 allows the flake raw material to be efficiently cooled and solidified in a short time, but the raw material is pressed by the upper and lower belts. If the cooling state of the raw material supplied to the flaker is not uniform, the oils and fats contained therein float on the surface, and the oil crystals of the obtained flakes tend to be unstable. Therefore, according to the present invention, the raw material is uniformly and efficiently cooled by the cooling device and is continuously sent to the flaker, thereby solving the above problems and efficiently producing flakes of uniform quality. Becomes possible. Of course, it is possible to cool and flake the flake material even with a single belt flaker.
[0029]

Accordingly, the cooked flake material is discharged from both the lower opening 226 and the side opening 228. Handles 229 are attached to the upper surface and the left and right side surfaces of the feeder 220 to facilitate the conveyance of the heavy feeder 220.
[0031]
The passage portion 221 has a height, that is, a width in a direction orthogonal to a triangular surface, which is the largest at the entrance portion 230 connected to the transport pipe 30 and whose cross section is circular, and whose lower opening portion 226 is smallest and whose cross section is rectangular. And the middle is formed by the surfaces connecting them.
[0032]

The discharge housing 250 prevents the produced flakes from scattering and guides the flakes to a downstream packaging device (not shown), a stock device (not shown), or the like. The crushing device 16 further rotates a suitably supported bearing device 260 which does not prevent the manufactured flakes from falling, a shaft member 262 which is supported by the bearing device 260 and extends to a lower portion of the discharge housing 250, and a shaft member 262. A suitable drive source (not shown) for the

The stirring blade 310 has a longitudinal edge close to the upper surface of the perforated screen 300, lifts the other longitudinal edge at an angle of 45 degrees from this portion, and rotates the flake material on the perforated screen 300 when rotated. In other words, the inclined surface is attached so as to press the flake material.
[0035]
Above the shaft member 262, a plurality of first pin members 320 extending radially around the shaft member 262 are provided at different heights and at different angular directions. The upper end of the shaft member 262 has a conical shape tapering upward. The first pin member 320 may be provided singly, and when a plurality of first pin members 320 are provided, they may be provided at the same height position. When the plurality of first pin members 320 are provided at different heights and in different angular directions, the flake material is efficiently pulverized and sized without stagnation and stagnation of the flake material on the perforated screen 300. It is preferable because it is possible.
