Next, a case where secondary drying of rice cracker dough is performed using the above-described secondary drying system will be described.
[0018]
In the figure, the secondary drying devices 1 are shown in a row of 6 units in 2 rows, a total of 12 units. However, not all secondary drying devices 1 are necessarily used when manufacturing rice crackers. As described above, the number of units to be used is determined by the processing amount of the rice cracker baking machine, the time required for secondary drying, and the like. For example, when the processing amount per hour of the baking machine 23 is 400 kg and it takes 4 hours to dry the moisture of 10 to 12%, one secondary drying is performed without using 12 secondary drying apparatuses 1. If 400 kg can be obtained by the apparatus 1, four secondary drying apparatuses 1 may be used.
[0019]
That is, first, the rice cracker dough of 400 kg ÷ 6 = 66.66 kg of 66.66 kg is added every 10 minutes to the six stirring cylinders 11 of the first secondary drying apparatus 1 through the supply means 2. Then, after 10 minutes, 66.66 kg of the rice cracker dough is fed into the six stirring cylinders 11 of the second secondary drying device 1 in the same manner at intervals of 10 minutes via the supply means 2. . Similarly, 400 kg each of the rice cracker dough is put into the third and fourth secondary drying apparatuses 11.

You may comprise so that it may throw in in the stirring cylinder 9 more.
[0022]
Next, when a predetermined time elapses, the rotary drum 8 stops when the inlet / outlet 9a of the second stirring cylinder 9 comes to the position of the outlet of the movable shooter 16, and as described above, a predetermined amount of rice cracker dough is removed. receive. In this way, when the third to sixth stirring cylinders 9 sequentially receive a certain amount of rice cracker dough, the supply of the rice cracker dough to the first secondary drying device is finished, and after a predetermined time has passed, The decoction dough is sequentially supplied to each stirring cylinder 9 of the secondary drying apparatus 1 as described above, and such decoction dough is supplied in a number corresponding to the processing amount per unit time of the baking machine 23. It is made for the secondary drying device 1 and repeated during the operation of the rice cracker baking machine 23. In the embodiment, since six secondary drying apparatuses 1 are arranged in two rows, the transfer conveyor 3 moves through the sorting conveyor 3a, and moves in the forward and reverse directions to move each of the two rows. A certain amount of rice cracker dough is supplied to each supply means 2 of the secondary drying apparatus 1.
[0023]
In this way, when the predetermined time has elapsed, the secondary drying time is sequentially finished from the rice cracker dough stored in the first stirring cylinder 9 of the first secondary drying device 1, The rice cracker dough after the secondary drying is finished by stopping when the entrance / exit 9a sequentially reaches the fixed shooter 21 of the discharging means 5 from the first stirring cylinder, and opening the lid 11 with the turning lever 23. It is discharged onto the feed conveyor 6 from the fixed shooter 21 to the baking machine 23.
[0024]
In this way, the rice cracker dough after the secondary drying can be automatically supplied one after another according to the processing capacity of the baking machine 23.
