[0002] Aseptic filling machines are equipment used for aseptic packaging of fluid foods. They can complete the filling and sealing of sterilized products in an aseptic environment. They are suitable for aseptic packaging of foods such as fruit juice, fruit pulp, jam, and dairy products. Currently, online sterilization (SIP) is often used.
[0003] In existing technologies, sterilization media combined with positive pressure air are used for protection to keep the filling chamber in a sterile state. However, when the corresponding batch of filling operations is completed, the machine needs to be stopped to change the corresponding filling media and adjust and replace the corresponding components. At this time, the positive pressure gas is in a stopped state, and the filling head exposed in the filling chamber is at risk of contamination. This leads to an increase in the frequency and intensity of subsequent SIP, which increases the operating cost. Moreover, the long-term high temperature and high pressure SIP cycle can easily cause thermal stress and mechanical fatigue to the filling valve, sealing ring, sensor and other components in the filling head, reducing their service life.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] The following is combined Figures 1-5 This invention describes an aseptic filling machine for beer and beverages.
[0025] In one embodiment, a beer and beverage aseptic filling machine includes a filling machine body 100 and a set of filling heads 200 installed inside it; it also includes a protective mechanism 300, the number of which is a set, the protective mechanism 300 is disposed outside the filling head 200 and is used to protect the filling head 200; wherein, the protective mechanism 300 includes two semi-circular plates 310 and a guide ring 320, the two semi-circular plates 310 are horizontally movable and seal the port of the filling head 200, the bottom of the semi-circular plates 310 has two arc-shaped grooves 311, and the guide ring 320 is located below the two semi-circular plates 310.
[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the side view of the guide ring 320 is convex in shape, and the bend in the middle of the guide ring 320 is chamfered.
[0027] In this embodiment, during the filling operation, the arc-shaped groove 311 sprays sterile gas. The gas is guided by the bend of the guide ring 320 and then separates in a ring shape, forming a protective air curtain outside the medium filling path to reduce contamination of the filling medium. During non-filling operations, the two semi-circular plates 310 can be used to shield and protect the port of the filling head 200 by relative movement, reducing the occurrence of external bacteria entering. The above method continuously protects the filling head 200, reduces the sterilization area, and thus effectively reduces the frequency and intensity of subsequent SIP operations, effectively reducing costs and shortening the pressure and heat exposure time of the internal components of the filling head 200, extending the service life of the equipment.
[0028] It should be noted that the main body of the filling machine in this application is model 100 Modulfill Bloc FS-C;
[0029] Because the filling head 200 is in a fully protected state, it can perform filling operations directly during the sterilization process in the filling area while ensuring the sterility of the filling bottles, thereby reducing the downtime of the entire filling system and improving filling efficiency.
[0030] like Figure 2 and Figure 3 As shown, a sleeve 210 is fixedly sleeved on the outside of the filling head 200, and two fixed boxes 220 are embedded inside the sleeve 210. A semi-circular plate 310 is slidably connected to the inside of the fixed box 220, and an electric push rod 221 that docks with the semi-circular plate 310 is provided on the fixed box 220.
[0031] The filling head 200 is covered by a sleeve 210 to protect its internal components. A fixing box 220 is used to provide storage space for the semi-circular plate 310. When protecting the port of the filling head 200, the semi-circular plate 310 can be moved by an electric push rod 221 to complete the protection operation.
[0032] It should be noted that the specifications and coverage of the sleeve 210 can be selected according to the specifications of the filling head 200 and the actual usage requirements.
[0033] like Figure 4 As shown, a slider is provided at the top of the guide ring 320, and the guide ring 320 is slidably connected to the lower part of the semicircular plate 310 through the slider.
[0034] The semicircular plate 310 and the guide ring 320 are connected by sliding. Since the two semicircular plates 310 are in synchronous motion, the force generated on the guide ring 320 is the same, so the position of the guide ring 320 can remain unchanged during the movement of the semicircular plate 310.
[0035] like Figure 2 and Figure 3As shown, a conduit 222 extending into the semi-circular plate 310 is installed on the fixing box 220. The conduit 222 is made of plastic.
[0036] Sterile gas is introduced into the semi-circular plate 310 through conduit 222 to form a protective air curtain. The use of plastic material allows for the normal delivery of sterile gas without affecting the movement of the semi-circular plate 310.
[0037] like Figure 2 and Figure 3 As shown, a miniature air pump 230 is installed on the outside of the sleeve 210, and an annular box 240 is fixedly sleeved on the outside of the sleeve 210 at the output end of the miniature air pump 230. One end of the conduit 222 is connected to the annular box 240.
[0038] The micro air pump 230 is activated to introduce sterile gas into the ring box 240, and then the sterile gas is introduced into the fixed box 220 for use through the conduit 222;
[0039] It should be noted that the input end of the miniature air pump 230 can be connected to the external aseptic chamber through a pipeline, so that even if the aseptic environment of the filling area is accidentally damaged, the aseptic filling operation will not be affected.
[0040] like Figure 2 and Figure 3 As shown, the guide ring 320 is located inside the sleeve 210, and the inner diameter of the guide ring 320 is larger than the inner diameter of the filling head 200.
[0041] This prevents the filling medium from coming into contact with the guide ring 320 during the filling operation, reducing the possibility of bacterial growth on the guide ring 320.
[0042] like Figure 1 As shown, a material hopper is provided on the main body 100 of the filling machine, and a set of material pipes for docking with the filling head 200 are installed on the material hopper.
[0043] A feeding pipe is arranged between the material pipe and the filling head 200, and a corresponding conveying pump and control valve are matched to complete the filling material conveying operation;
[0044] It should be noted that this type of delivery method is a mature existing technology, and will not be elaborated upon here.
[0045] Working principle: When the filling area is under sterile conditions, the filling operation is carried out. When the filling head 200 delivers the medium, the micro air pump 230 is activated, causing the arc-shaped groove 311 to spray out sterile gas. Subsequently, guided by the guide ring 320, a protective air curtain is formed to protect the filling medium. After the filling operation is completed and the filling system is shut down, the electric push rod 221 can be used to drive the two semi-circular plates 310 to contact each other. Together with the sleeve 210, the filling head 200 is covered and protected. When the filling operation is resumed, since the filling head 200 is in a real-time protected state, the user can introduce high-temperature and high-pressure sterilization medium into the remaining area. Compared with traditional sterilization treatment, the sterilization range is reduced, thereby reducing the sterilization frequency and intensity, reducing the cost of use and the duration of heat and pressure on the internal components of the filling head 200.
[0046] It should be noted that the miniature air pump 230 and electric actuator 221 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the miniature air pump 230 and electric actuator 221 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.
[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
