The silica gel drying agent judges whether the water absorption is saturated or not through the color after absorbing the water, and discharges the water in the silica gel drying agent in a heating mode after the silica gel drying agent is saturated, so that the silica gel drying agent can be reused, and is very convenient and economical.
Use the utility model discloses when doing the drying again to the laver, earlier pass through rectangle magnet piece 13 and rectangle iron plate 14 with the laver that needs the drying and fix on rectangle backup pad 2. Then, rectangular support plates 2, to the upper end surfaces of which laver is fixed, are installed one by one inside the drying box 1. Then plugs at one ends of the electric heater 5 and the air suction pump 11 are inserted into a socket connected with an external power supply device, the baffle 7 is inserted into the baffle mounting frame 6, air at the bottom of the drying box 18 is heated under the action of the electric heater 5, hot air moves upwards and contacts with the laver through the air holes 3, and therefore the laver is dried. The surfaces of the rectangular magnet block 13 and the rectangular iron block 14 are sleeved with a waterproof protective film; reduced the utility model discloses a long-term back rectangle magnet piece 13 of using and rectangle iron plate 14 cause behind the corrosion such as vapor the untight probability of cooperation between the two because of the surface, have prolonged the utility model discloses a life.
Moreover, the laver can be firmly fixed on the rectangular support plate 2 by the matching use of the rectangular magnet block 13 and the rectangular iron block 14, other fixing devices are not needed, and the phenomenon that the appearance of the laver is affected due to the wrinkles after the laver is dried can be effectively avoided.
In this embodiment, the length of the rectangular plate 12 is equal to the width of the drying box 1, the width of the rectangular support plate 2 is smaller than the width of the drying box 1, so that the air heated at the bottom can flow upward from the gap formed between the rectangular support plate 2 and the drying box 18, and finally the air humidified by the dried laver flows through the drying agent in the drying box 18 under the action of the air pump 11, at this time, the water vapor in the air is adsorbed by the drying agent, thereby removing the moisture in the heated air under the condition of not reducing the temperature of the heated air, reducing the loss and waste of heat, the hot air from which water has been removed by the action of the suction pump 11 is again sucked to the interior of the lower part of the drying box 1, heated again by the electric heater 5, since the temperature of the hot air at this time is relatively small in temperature drop, so that the electric heater 5 can heat the laver for a second time only by heating the laver for a short time. Whether the laver has reached the drying standard is judged by observing a moisture meter 8 (TK 100 moisture meter is selected) inserted in the top of the drying box 1 when the laver is heated. When the drying reaches the standard, the electric heater 5 and the air pump 11 are disconnected with the circuit of the external power supply equipment, the baffle 7 is taken down after the electric heater and the air pump are properly cooled for a certain time, the rectangular supporting plate 2 is taken down, and finally the dried laver on the upper end surface is taken down to finish the drying work of the laver.
Compared with the traditional drying device, the utility model discloses need not to heat the relatively lower "cold" air of external temperature repeatedly, heat time is shorter, and is higher to thermal utilization ratio, and is more energy-conserving. The silica gel drying agent judges whether the water absorption is saturated or not through the color after absorbing the water, and discharges the water in the silica gel drying agent in a heating mode after the silica gel drying agent is saturated, so that the silica gel drying agent can be reused, and is very convenient and economical.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. In addition to the above embodiments, other embodiments of the present invention are also possible. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention as claimed.
