Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for collecting surplus hand flour used to prevent sticky foods from sticking. Conventionally, in the manufacturing process of foods such as biscuits, crackers, pies, pastries, rice crackers, and noodles using the dough sheet rolling method, the sheets are processed into sheets before and after various processes such as rolling, folding, cutting, and forming. In order to prevent the dough from adhering to conveyors, rolls, cutting molds, etc., it is common practice to evenly spread hand flour (flour) on the top and bottom surfaces of dough sheets. Generally, hand flour tends to be used in excess of the required amount, so if a dough sheet with a lot of excess hand flour is cut and roasted as it is, the surface of the baked product will not be well finished. It has a dull, white, powdery appearance and is a cause of lowering the commercial value, especially in products such as pies and pastries that require a glossy appearance. In addition, the hand flour collected before roasting the dough sheet can usually be reused after being sieved, but the hand flour that has been roasted once attached to the dough sheet cannot be collected after roasting. Since the flour cannot be reused, it is essential to efficiently collect the flour before roasting to improve the yield. For this reason, surplus hand flour has traditionally been collected manually or mechanically. Excess hand flour is removed by gravity, mechanical scraping, etc. in the transition gap between sheet conveyors, and excess hand flour sprinkled on the top surface of the dough sheet is removed manually with a brush, etc. Methods of collecting the material include scraping it off with a paper towel, or bringing the nozzle of a removal device with an absorption opening close to the top surface of the dough sheet and suctioning it. However, manual methods are inefficient and
The absorption method can absorb and collect excess hand flour that is relatively weakly attached to the upper surface of the dough sheet, but excess hand flour that is firmly attached to the upper surface of the dough sheet, especially the upper surface of soft dough sheets such as pies and pastries, can be absorbed and recovered. Difficult to absorb and recover. In addition, if the suction force is increased to collect excess hand flour that has been carried on, if the dough sheet itself is lightweight, such as for pies, pastries, etc., there may be problems such as it being lifted in the suction direction of the suction device or being sucked in. There are defects that occur. The inventors of the present invention solved the above-mentioned defects in the conventional surplus hand flour removal work and the equipment used to perform it, and conducted research to obtain a device that can reliably and efficiently remove surplus hand flour. The dough sheet is conveyed along a dough sheet conveyance path, a brush moving device is disposed above the conveying path, and the brush driving device is provided with an endless track and a brush attached to the track. The lower side of the fabric sheet is arranged to face parallel to the fabric sheet conveyance path at a predetermined interval, and its rotation locus forms a predetermined angle with the fabric sheet conveyance path so that it rotates against the conveyance of the sheet. I was able to solve the problem by diagonally sweeping away the excess hand powder that had been sprinkled on the surface. The present invention will be explained by way of an example shown in the drawings, as shown in FIG. Reference numeral 1 denotes an existing dough folding device, in which a dough sheet 2 made into a certain thickness by a rolling device (not shown) is folded by the device and continuously placed on a dough sheet conveyor 4 that runs on a table 3. be done. Therefore dough sheet 2
is continuously transported on a dough sheet conveyor 4, and is passed through two to many pairs of rolling rolls 5, 5'.
After being supplied to the conveyor 4' and rolled, the
Above and across the conveyor 4', a hand flour spreader 6 is fixedly installed between the tables 3', 3', and the conveyor 4', that is, the dough sheet Hand powder (flour) is sprinkled on the dough sheet 2' according to the running speed of the dough sheet 2'. The dough sheet 2' sprinkled with hand flour is then rolled to a predetermined thickness by one or more rolling rolls 7, and after the hand flour is attached, it is further conveyed by a conveyor 4'', and then transferred to a cutting and forming machine. The dough is cut into a predetermined size by 8. In Fig. 1, 9 indicates the entire brush moving device, which receives the dough sheet 2 cut by the cutting and forming machine 8 and removes excess hand flour. As shown in FIG. 2, the brush moving device 9 is placed on a loading platform 10 that is fixed to diagonally straddle a conveyor 4'' running on a table 3''. It is preferably fixed diagonally across the road at an angle of 30 degrees to 45 degrees.Vertically adjustable bearings 11, 11, . . . are provided near each end of the loading platform 10, and left and right vertically adjustable bearings 11 , 11. Therefore, the height of the drive shafts 12, 12 can be adjusted up and down by rotating the screws 13, 13, . . . of the vertically adjustable bearings 11, 11. In addition, one drive shaft 12 is extended outward, a pulley 14 is fixed to the end thereof, and the drive shaft 12 is interlocked with a motor 15 with a transmission via a belt 16.The loading platform 10,
Inside the shaft 10, two connecting rods 17, 17 are provided in parallel between the front and rear shafts 12, 12, and chain wheels 18, 18 are fixed to the front and rear shafts 12, 12, respectively. Then, chains 19, 19 are stretched in parallel to the respective connecting rods 17, 17, and rotated in a direction (B) opposite to the traveling direction (A) of the conveyance path. The chain 1
9 and 19 can be of any type that has endless tracks and can rotate at the same speed on the left and right sides, for example, they may be replaced with synchro belts. Further, the brush 20 to be described later may be one piece as long as it can be fixed at the center without wobbling in the left and right directions. A brush 20 is fixed parallel to the shaft 12 between the left and right chains 19, 19, and the number of brushes 20 may be one to a small number, but preferably a large number are arranged radially at equal intervals, and the brushes 21 of the brush 20 are fixed. should always be in contact with the dough sheet 2. The position of the brush tip 21 is adjusted by rotating the screw 13 described above. The brush 20 is made of a wooden, metal, or plastic flooring material with a brush 21 made of plastic or long hairs derived from animals and plants, and the long hairs have different lengths, thicknesses, and waistbands. The strength must be selected appropriately, and those with a length of 50 mm or more and fine bristles that have an appropriate repulsive force are suitable for use. In addition, if the brush 21 is hard and has a strong repulsive force, there is a risk of damaging the surface of the dough sheet, especially soft dough sheets such as pies and pastries. The scraping effect becomes smaller. In addition, it is necessary to implant the hair in a firm manner to prevent hair removal and foreign matter contamination. still,
Reference numeral 22 is a cover for preventing the excess powder removed by the brush 20 from scattering around. The brush moving device 9 of the present invention is constructed as described above, and the dough sheet 2 cut by the cutting and forming machine 8 is placed on the conveyor 4″ and conveyed, and reaches the lower part of the brush moving device 9 . , the excess brush stuck to the surface is swept up, but the brush movement device 9
is installed at an angle of 30 to 45 degrees with respect to the dough sheet conveyance path, in other words, the dough sheet conveyor 4'', and its brush 20 is rotated in the direction B so as to be diagonally opposite to the traveling direction A of the dough sheet 2. Therefore,
The hand flour is swept diagonally horizontally and placed on dough sheet 2.
Even powder stuck to the surface can be removed efficiently. If the apparatus of the present invention is not used and is arranged to rotate in a normal direction perpendicular to the direction of movement of the dough sheet 2 or diagonally at an angle of 60 degrees, the amount of flour produced by hand will be lower than in the case of the example shown in the figure. The recovery rate is extremely low. In addition to the example shown in the drawings, if a conventional suction-type hand powder collection device (not shown) is provided behind the brush moving device 9 , the hand powder can be collected even more completely. As mentioned above, the cut dough sheet 2 from which the hand flour has been removed and cleaned is placed in the oven 23 and baked, but since almost no hand flour remains on the cut dough sheet 2, the product has a good gloss. It can be baked to The apparatus of the present invention can be used with great effect for breads, biscuits, rice crackers, and a wide range of other general foods that use hand flour.
