Example III
Fig. 7 and 8 show an embodiment of a tunnel sterilizing dryer according to the present invention, which includes a bottle conveying mesh belt 8, and a preheating module 91, a heating module 92, and a cooling module 93 sequentially disposed along a conveying direction of the bottle conveying mesh belt 8, wherein the heating module 92 and the cooling module 93 each include the above-mentioned case, the case body 1 in the case serving as the heating module 92 is provided with the first heater 71 in the circulation duct 6, and the case body 1 in the case serving as the cooling module 93 is provided with the liquid cooler 72 in the circulation duct 6.
The tunnel sterilizing dryer, the heating module 92 and the cooling module 93 each comprise the above-mentioned cabinet, and thus have the same advantages as described above. During operation, the bottle loops through preheating module 91, heating module 92 and cooling module 93 through defeated bottle guipure 8, carries out preliminary heating in preheating module 91's box body 1 and heaies up, disinfects in heating module 92's box body 1, carries out the cooling in cooling module 93's box body 1. The primary heating and sterilizing process is as described above, and will not be described again. The specific process of cooling is as follows: referring to fig. 4, during operation, the reversing fan 5 introduces cold air cooled by the liquid cooler 72 at the upper part of the circulating air duct 6 into the positive pressure cavity 3 from the side surface, so that the air pressure in the positive pressure cavity 3 is gradually increased, then the air in the positive pressure cavity 3 flows downwards again, flows into the bottle conveying channel 2 after being filtered by the air filter 4, cools the bottle body in the bottle conveying channel 2, and then the hot air flows into the circulating air duct 6 from the bottle conveying channel 2, and is cooled again when passing through the liquid cooler 72, so that internal circulation is realized.
Further, in the present embodiment, the case body 1 in the case serving as the cooling module 93 is further provided with a second heater 73 in the circulation duct 6, the liquid cooler 72 is detachably connected to the door via the first cover 61, and the second heater 73 is detachably connected to the door via the second cover 62 (for example, detachably connected by a fastener such as a bolt, a screw, or the like). Specifically, as shown in fig. 3, the liquid cooler 72 does not work, the reversing fan 5 guides the hot air heated by the second heater 73 at the upper part of the circulating air duct 6 into the positive pressure cavity 3 from the side surface, so that the air pressure in the positive pressure cavity 3 is gradually increased, then the air in the positive pressure cavity 3 flows downwards again, flows into the bottle conveying channel 2 after being filtered by the air filter 4, heats and sterilizes the bottle body in the bottle conveying channel 2 on line, flows into the circulating air duct 6 from the bottle conveying channel 2, and is heated again when passing through the second heater 73, so as to realize the function of on-line sterilization. Referring specifically to fig. 4, when the cooling module 93 does not require an on-line sterilization function, the second heater 73 may be removed, the sealability in the case body 1 may be maintained by the second cover plate 62, or the second heater 73 may not be provided at the time of shipment; referring specifically to fig. 5, further, when the cooling module 93 does not require the liquid cooling function but only the partial air cooling function, the liquid cooler 72 may be removed, the sealing property in the case body 1 may be maintained by the first cover 61, or the liquid cooler 72 and the second heater 73 may not be provided at the time of shipment.
As a preferred embodiment, the preheating module 91 and the case body 1 (specifically, the case body 1 of the preheating module 91 and the case body 1 of the heating module 92) and the adjacent case bodies 1 are connected by expansion rings 94. The expansion ring 94 can stretch out and draw back, can adapt to the deformation that expansion with heat and contraction with cold led to in each box body 1 working process, makes each box body 1 remain sealing connection throughout, avoids taking place to leak, and the reliability is good.
