Description
Technical field
The present invention relates to a kind of disinfection processing equipment and disinfection processing method of coiled material cardboard bag sterile packaging machine.
Background technology
In food industry, paper roll shaping packaging system is present most popular packaging system, and the food liquid that is used for commercial sterilization is fruit juice for example, beverage, the aseptic packaging of food such as milk.Packing are supplied with wrapping machine continuously by paper roll, carry out can, involution and cutting through a series of forming processes.The material that is used for aseptic packaging comes down to a kind of composite material, is paper, polyethylene, aluminium foil, the compound cardboard of sarin resin multi-layer, and wherein paper is structural materials, and aluminium foil then is a high barrier material.Coiled material cardboard bag aseptic packing system is the most representative with the Tetra Pak sterile packaging apparatus of Sweden Tetra Pak company, and its main job procedure is: the moulding → filling of the sterilization → packing of the sterilization → packing of the generation → machine of filtrated air, seal and cut from.Each operation keystone configuration and mechanism are:
1. the generation of filtrated air.Filtrated air all is provided to provide when preceding sterilization of aseptic packaging operation and material filling.The generation of the filtrated air of sterile packaging machine is compressed suction air by the liquid-ring type compressing pump, and suction air comprises part desinfection chamber return air, and the sealing water ring can be with residual H in the return air that sucks in the pump
2O
2The liquid flush away.Extrude air and separate moisture, enter airheater then and be heated to 360 ℃ through gas-water separation.The heated sterile air of coming out from temperature booster through about cools down to 120 ℃, feeds desinfection chamber in order to keep malleation again, guarantees that the space, filling area is aseptic.Filtrated air is with the H of residual evaporation simultaneously
2O
2Take away, flow back to the liquid-ring type compressing pump through aspirate tube again and use.
2. the sterilization of machine.Before the aseptic packaging, all directly or indirectly all will be sterilized with the contacted machine of aseptic material position.Adopt hydrogen peroxide to do sterilization, at first utilize area of heating to the 280 ℃ operating temperature of heated sterile air preheating atomizer after, with 35% predetermined H
2O
2Solution is sprayed onto uniformly by nozzle on the area of heating of atomizer, H
2O
2Be heated gasification, activate, take away the surface of the hydrogen peroxide of gasification by thermal current subsequently to desinfection chamber and other parts subject to sterilization of machine.H
2O
2Spray amount, time control by operatorless device, to guarantee best sterilization effect.Heated sterile air makes H
2O
2Resolve into water, water evaporates and the desinfection chamber automatic drying.
3. the sterilization of packing.Packing at first are full of 35% H by one
2O
2The sterilization groove of solution (75 ℃), its soak time can preestablish according to the sterilization requirement.Then, through extruding squeeze roll and air doctor blade (120 ℃), remove residual H
2O
2, enter desinfection chamber at last.
4. Bao Zhuan moulding, filling, seal and cut from.After packing enter desinfection chamber, rely on three profile members to form paper web.Paper web is at vertical back seal.Aseptic goods enter paper web by feed pipe, and the liquid level of goods is controlled by floating drum in the paper web, and sealing all of packaging product once carried out in the material liquid level.Thereby can obtain the packaging product that content is full of fully.The displacement of product is by holding device.The horizontal sealing of packaging product adopts electronic heating to seal.Just form the package of pincushion after sealing.The hermetic unit that cuts off between the pillow packs just can be finished independent aseptic pillow packing.
Know in the above-mentioned production technology industry, therefore be not described in detail.This class wrapping machine is widely used in the food industry, the effect excellence when its packaging system carries out disinfection sterilization, and use is gratifying and safe and reliable.
Simultaneously as can be known according to above description:
1) the packaging system filtrated air adopts the method for high-temperature sterilization to generate, and promptly at first is air heating to 360 ℃ is sterilized, and then it is cooled to 120 ℃, to supply with sterilization and to keep the aseptic malleation in filling area to use.Therefore energy resource consumption is bigger.
2) use 120 ℃ of filtrated airs, cause defectives such as packaging material bubbles, becomes fragile, fracture easily.Simultaneously also cause the mechanical component gap change easily, cause problems such as machinery is stuck.
3) wrapping machine need make water as sealing medium when using the liquid-ring type compressing pump that pressure air is provided, and causes water resources consumption bigger.

Set up independent CIP washing system.During cleaning, filling tube 8 is connected to cleans counter flow pipe 32, and the cleaning liquid that self-cleaning pump 33 comes out is through cleaning valve 9(B valve), flow-controlling gate 10, filling tube 8 flow back to washer jar 34, cleaning process and technology press known way and are controlled.During sterilization, will clean counter flow pipe 32 and connect Automatic steam trap Trap 12, and close the 6th valve 35 on the pipe blow-through, opening steam cock 36 can be to the sterilization of can pipeline.
The disinfection processing method of a kind of aseptic packing system provided by the invention, step is:
Step 1, formation desinfection chamber: the outlet of preceding desinfection chamber 19, last desinfection chamber 18, drying chamber 17 and sterilization groove 16 is ganged up in one, form a relative fully enclosed space, this relative fully enclosed space is referred to as desinfection chamber;
Step 2, generate filtrated air: air-filtering arrangement forms filtrated air and sends in the desinfection chamber filtering accuracy 0.1-0.2 μ m, 45 ℃ of outlet filtrated air temperature after with air filtration;
The sterilization of machine before step 3, the aseptic packaging: can pipeline 8, flow-controlling gate 10 and filling part 11 are adopted steam sterilization, to other directly or indirectly adopts the hydrogen peroxide sterilization with the contacted position of aseptic material in the desinfection chamber;
The step of steam sterilization is: 135 ℃ of steams enter filling tube 8, flow-controlling gate 10, filling part 11 through cleaning valve 9 and carry out sterilization, remove steam trap 12 after sterilization is finished, and again fill head are taked the hydrogen peroxide dipping sterilization behind the tube sealing;
The step of hydrogen peroxide sterilization is: with 35% H
2O
2(40 ℃) solution makes whole desinfection chamber be full of the H of atomizing disperse by atomizer 14 even must being sprayed onto in the desinfection chamber
2O
2Solution;
The sterilization of step 4, packing: packing 15 at first are full of 35% H by one
2O
2The sterilization groove 16 of (40 ℃) solution, its soak time can preestablish according to the sterilization requirement, then passes through the H of drying chamber 17 with packing 15 remained on surface
2O
2Solution dries up, and arrives to go up desinfection chamber 18 again, carries out ultraviolet sterilization by the ultraviolet lamp 13 in the desinfection chamber 18;
Step 5, packing 15 rely on profile member to form paper tube from last desinfection chamber 18 desinfection chamber 19 before guiding roller enters.Packaging material tube sealing in a known way in the vertical forms continuous vertical longitudinal sealing pipe, then leave desinfection chamber, in fact, packaging material tube forms the extendible portion of desinfection chamber, and the continuous filling food that is full of, then it is sent in shaping and the transverse sealing device, forms aseptic form pillow packs.Therefore this part is no longer carefully stated only as the machine component part.
