Technical Field
[0001] The utility model belongs to the technical field of packaging film sterilization, and in particular relates to a sterilization device used for the production of food packaging films. Background Art
[0002] Foods need to be packaged in packaging films during production. Since the packaging films are in direct contact with the food, in order to ensure food safety, the packaging films need to be sterilized after production. Among them, the method of sterilizing the packaging films with high-temperature steam is widely used because of its short sterilization time and good sterilization effect.
[0003] The "sterilization device for food packaging film production" disclosed in the application number "CN202321394601.6" heats water to boiling through a plurality of heating tubes at the bottom of the heating box. The steam generated by the heating is transported to two exhaust pipes through two insulation pipes under the rotation of the fan blades, and the transportation efficiency is higher. Then, the two sides of the food packaging film are sterilized through the exhaust holes on the surface of the exhaust pipe. At the same time, the insulation box has a good insulation effect. According to the sterilization characteristics of hot air, it is convenient to quickly sterilize the packaging film in the transportation state, which is more efficient.
[0004] However, in actual applications, since the packaging film is in a conveying state, the packaging film will continue to pass between the two insulation boxes, and the cold air from the outside will easily enter the insulation box from the gap between the packaging film and the insulation box, thereby generating heat exchange with the high-temperature steam used for sterilization inside the insulation box, causing the steam temperature to drop and affecting the sterilization effect. Moreover, when the high-temperature steam contacts the packaging film for sterilization, the surface temperature of the packaging film is relatively low, causing the high-temperature steam to condense on the surface of the packaging film. At this time, when the packaging film passes through the insulation box, there are water droplets on the surface of the packaging film, causing external dust and other impurities to easily adhere to the surface of the packaging film through the water droplets.
