技术领域Technical field
本发明涉及食品、药品包装机械技术领域，尤其涉及一种用于干燥机加热段和冷却段的箱体及隧道式灭菌干燥机。The invention relates to the technical field of food and pharmaceutical packaging machinery, and in particular to a box used in the heating section and cooling section of a dryer and a tunnel-type sterilizing dryer.
背景技术Background technique
均布性是GMP（Good Manufacturing Practice of Medical Products，药品生产质量管理规范）中关于灭菌的一项重要指标，它要求灭菌设备内各点都到达预定的灭菌温度。灭菌设备温度分布不均匀是其无法通过验证的重要原因，在温度分布不均匀的灭菌设备中，部分容器经过灭菌段所获得的干热灭菌热效应降低，从而达不到除热原效果。为此，灭菌设备的热分布已受到普遍关注。专利文献CN 101548788 A公开了一种用于热风循环式灭菌干燥机的热均布调节机构，其结构简单紧凑、成本低廉、便于清洁和维修，提高了箱体热均布性。Uniformity is an important indicator for sterilization in GMP (Good Manufacturing Practice of Medical Products). It requires that all points in the sterilization equipment reach the predetermined sterilization temperature. The uneven temperature distribution of sterilization equipment is an important reason why it cannot pass the verification. In sterilization equipment with uneven temperature distribution, the thermal effect of dry heat sterilization obtained by some containers after passing through the sterilization section is reduced, so that the depyrogen removal is not achieved. Effect. For this reason, the heat distribution of sterilization equipment has received widespread attention. Patent document CN 101548788 A discloses a heat uniform distribution adjustment mechanism for a hot air circulation sterilization dryer. The structure is simple and compact, low in cost, easy to clean and repair, and improves the heat uniformity of the box.
现有的灭菌干燥机主要包括输瓶网带及沿输瓶网带的输送方向依次设置的预热段箱体、加热段箱体和冷却段箱体，箱体内部采用风机强制对流，也即风机直接朝向下方的输瓶网带送风，温度及风速均匀性较差，通常需要设置2台风机和2台变频器来控制温度，导致设备的结构复杂、尺寸大、成本高。冷却段箱体的冷却方式有风冷和液冷两种（液冷的冷却介质通常为冷却水）。其中风冷型结构为从洗烘间采房间风对容器药瓶进行冷却，热交换后的热风通过管道排出室外；水冷型结构风流为内循环，即和容器药瓶进行热交换后的热风经过液体冷却器降温后重新回到层流风机进行下一个冷却循环。两种冷却方式之间无法实现兼容，不同功能段箱体之间的通用性、兼容性差，设备零件多、加工不方便、功能共性弱导致预热段和加热段模块的箱体种类达到6种，冷却段模块的箱体种类达到5种。The existing sterilization dryer mainly includes a bottle conveying mesh belt and a preheating section box, a heating section box and a cooling section box arranged sequentially along the conveying direction of the bottle conveying mesh belt. The inside of the box uses a fan to force convection, and That is, the fan directly supplies air to the bottle conveying belt below, and the uniformity of temperature and wind speed is poor. It is usually necessary to set up 2 fans and 2 frequency converters to control the temperature, resulting in a complex structure, large size, and high cost of the equipment. There are two cooling methods for the cooling section box: air cooling and liquid cooling (the cooling medium of liquid cooling is usually cooling water). Among them, the air-cooling structure uses room air from the washing and drying room to cool the containers and medicine bottles, and the hot air after heat exchange is discharged outside through the pipe; the water-cooling type structure has an internal circulation, that is, the hot air after heat exchange with the containers and medicine bottles passes through After the liquid cooler cools down, it returns to the laminar flow fan for the next cooling cycle. There is no compatibility between the two cooling methods. The versatility and compatibility between boxes in different functional sections is poor. There are many equipment parts, inconvenient processing, and weak functional commonality. As a result, there are 6 types of boxes for preheating section and heating section modules. , there are 5 types of cooling section module boxes.
冷却段箱体需要保证无菌环境，现有设备一般是在使用前对冷却段箱体进行无菌处理，无法实现SIP（Sanitize in Place，原位消毒系统或者在线灭菌系统），需要停机等待消杀，耗时长，影响生产效率。The cooling section box needs to ensure a sterile environment. Existing equipment generally performs sterile treatment on the cooling section box before use. SIP (Sanitize in Place, in-situ disinfection system or online sterilization system) cannot be implemented and needs to be shut down and waited. Disinfection takes a long time and affects production efficiency.

Compared with arranging a fan in the positive pressure chamber, the fan directly forces air downwards. In the present invention, the air is introduced horizontally into the positive pressure chamber through the reversing fan and then is released under pressure. Under the action, it passes vertically downward through the air filter and enters the bottle delivery channel, and then flows horizontally to the circulating air duct and vertically enters the reversing fan air inlet through the first heater or surface cooler, which is beneficial to improving the uniformity of temperature and wind speed. To meet GMP requirements; there is a door on one side of the box, and a mounting part on the door. The mounting part is equipped with a pull-out first heater or liquid cooler. When the first heater or liquid cooler is installed on the door, When the heater is used, the first heater is used to heat the air in the circulating air duct, and the box can be used as the heating module of the tunnel sterilization dryer; and when a liquid cooler is installed on the box door, the liquid cooler is used to heat the air. The air in the circulating air duct is cooled, and the box can be used as the cooling module of the tunnel sterilization dryer. At this time, the box air inlet and box outlet on the box are closed to realize the liquid cooling function; further , if the liquid cooler is removed and the box air inlet and box air outlet on the box are opened, the fan will take room air from the washing and drying room to cool the medicine bottles, and the hot air after heat exchange will be discharged through the pipe Outdoor, the air cooling function is realized; the overall structure is simple, low cost, and has very good compatibility, which can greatly reduce the number of different types of modules.
进一步地，预热模块的箱体本体内的循环风道上设有测试口，便于检测循环风的温度和箱体本体内部的压力。Furthermore, a test port is provided on the circulating air duct in the box body of the preheating module to facilitate detection of the temperature of the circulating air and the pressure inside the box body.
本发明公开的隧道式灭菌干燥机，加热模块和冷却模块均包括上述的箱体，因而同样具有上述优点。In the tunnel-type sterilization dryer disclosed by the present invention, both the heating module and the cooling module include the above-mentioned box, and therefore also have the above-mentioned advantages.
