The present invention also provides a rice flour drying method, which uses the rice flour dryer 100 as described above, and the rice flour drying method comprises the following steps:
S10: preheating: the hot air source is opened to send hot air into the drying cavity 20a, so that the temperature range in the drying cavity 20a is controlled between 35 ℃ and 46 ℃, and the carrying mechanism is opened to carry out no load for 10min to 15min;
In the step, the hot air source mainly comprises an air pump and a heating device, the heating device is arranged corresponding to the air pump, air generated by the air pump is heated by the heating device and then is conveyed to the air inlet 20b and then enters the drying cavity 20a, the hot air is kept stand for 10min-15min after entering the drying cavity 20a, during the period, the temperature in the drying cavity 20a is continuously measured by using an infrared temperature tester, and when the temperature is raised to 35-46 ℃, the carrying mechanism is started to be idle for 10min-15min, so that the carrying mechanism is fully heated, and the temperature in the drying cavity 20a is balanced, and the drying effect of rice flour is better.
S20: and (3) drying: placing rice flour into a carrying mechanism through a flour hanging rod 200, sending the rice flour into a drying cavity 20a, controlling the carrying mechanism to operate according to preset power, so that the residence time of the rice flour in the drying cavity 20a is 40-50 min, and spraying purified water into the drying cavity 20a during the period, so that the humidity range in the drying cavity 20a is controlled to be 30-40% RH;
In this step, a plurality of rice noodles are hung on the powder hanging bars 200, both ends of which are exposed and hung on the carrying member 32 of the carrying mechanism, so that in order to enable the hot air to be fully contacted with the rice noodles, the distance between two adjacent powder hanging bars 200 should be controlled between 1cm and 3cm, thus being capable of guaranteeing the drying effect and simultaneously having larger drying efficiency. According to the size of the drying cavity 20a, the running power of the carrying mechanism is controlled, so that the residence time of the rice flour in the drying cavity 20a is 40-50 min, and the rice flour can be thoroughly dried. In this step, not only the operation power of the carrying mechanism can be controlled, but also the operation mode of the carrying mechanism can be controlled, for example, within 40min-50min, the carrying mechanism moves by a distance of the drying cavity 20a, so that the original and dried rice flour is completely sent out from the discharge hole 20d, that is, the drying mode is batch drying. The drying mode can be selected and controlled according to actual needs, and the production is more convenient. Meanwhile, in order to ensure the taste of the rice flour, the application needs to spray purified water into the drying cavity 20a in the drying process so as to ensure that the humidity range is controlled between 30% RH and 40% RH, thus avoiding the situation that the rice flour is too dry and has insufficient toughness to break.
It should be understood that the pure water spraying may be performed manually, or a spray head is installed in the drying cavity 20a, and the pure water is automatically sprayed into the drying cavity 20a, which is not described herein.
S30: post-treatment: the cooling fan is adopted to directly blow the discharging hole 20d of the drying box, so that the dried rice flour flowing out of the discharging hole 20d is rapidly cooled, and the surface moisture is dried.
In this step, a cooling fan can be placed at the discharge port 20d according to the actual situation and the local situation after the rice flour is dried, the air outlet direction is the side of the rice flour, that is, the blown air quantity enters the gaps between the plurality of powder hanging rods 200, the cooling speed of the dried rice flour can be increased by setting the cooling fan, and meanwhile, the moisture on the surface of the dried rice flour is dried, so that the dried rice flour is convenient to store.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
