Definitions

  • the invention relates to a device for the automated cleaning of upwardly open containers with a container opening, a container bottom and a container wall, in particular in the food industry.
  • the invention relates to a method for the automated cleaning of upwardly open containers with a container opening, a container bottom and a container wall, in particular in the food industry.
  • Devices and methods for automatically cleaning containers are known in many industrial areas, such as e.g. in the food or pharmaceutical industry, widely used because they minimize the labor input and ensure a fixed cleaning result, which is an indispensable criterion in today's hygiene requirements.
  • CIP cleaning in place
  • Containers in particular open-type tanks, are also used in many industrial areas, e.g. the food industry, often in use. They allow easy visual monitoring of the process running in the tank and can also be easily loaded or unloaded manually. The cleaning of such open systems, however, has so far been possible only with a high level of human and especially physical use. Other constructions, such as large lid openings or removable lids are technically difficult to realize in large containers, also very expensive and microbiologically questionable.
  • the invention is therefore based on the object to provide a device and a method of the type mentioned above, which overcome the above-mentioned disadvantages.
  • At least one line element adapted to the contour of the container opening is arranged with at least one row of holes in the upper region of the inside of the wall of an upwardly open container. Since the at least one line element can be controlled with a defined cleaning program, the automation of the cleaning is combined with a simple visual controllability. Since the cleaning and the flow of the cleaning agent are visible, the cleaning efficiency in terms of material usage and process time can be increased. On the one hand, it is possible in a simple manner to selectively use cleaning agents in the area of contamination and, on the other hand, to stop the cleaning process at the time when it can be seen that the desired cleaning result has already been achieved.
  • cleaning agent is applied from a small distance from at least one stationary conduit element on the inside of the container wall.
  • the cleaning agent which may bounce off the container wall in the direction of the container opening and possibly has dirt particles, is removed by means of the cover in the direction of the container bottom distracted.
  • the side of the cover facing the conduit element is cleaned by means of cleaning agent emerging from the stationary conduit element.
  • the invention may e.g. used in a brewery, but also in other areas of the food industry and other industrial areas where open topped tanks are used.
  • FIG. 1 shows an embodiment of the device according to the invention in a perspective illustration
  • FIG. 2 shows the device from FIG. 1 in a sectional view
  • FIG. 3 shows a stretched section of a line element
  • FIG. 4 shows a schematic plan view of the device in a ring - or ring segment-shaped embodiment.
  • Fig. 1 shows a section through a part of an upwardly open container with a container opening, a container bottom and a container wall, with respect to the inside of the container wall 1.
  • the container can e.g. an open, cylindroconical fermentation tank, as it is used in a brewery for the fermentation of wort.
  • the cross-section of these tanks is in practice, as indicated in Fig. 1, mostly round, wherein the device according to the invention is not limited to the use of round containers, but also for containers with any, e.g. rectangular, cross-section can be applied.
  • a line element 2 in the upper region of the inside of the container wall 1 can be seen in detail, which in this exemplary embodiment has a substantially round cross-section and extends in the manner of a ring or ring segment. Since the conduit element 2 in its spatial extent to the contour of the Container opening is adjusted, it will be rectangular in the case of a rectangular container, for example, or consist of straight pieces, which are each arranged on a wall.
  • cleaning agent is applied from a small distance from the conduit element 2 on the inside of the container wall 1.
  • the line element 2 is arranged in the region of a cover 3 arranged parallel thereto and surrounding the line element 2 in regions of approximately 180 °. The bouncing off of the container wall 1 in the direction of the container opening, possibly dirt particles having detergent is deflected by means of the cover 3 in the direction of the container bottom.
  • the preferably curved cover 3 is also cleaned at its the line element 2 side facing in the automatic cleaning.
  • a special cleaning program is necessary, which provides for standardization of the cleaning process by depositing a well-defined cleaning program, setting down times, volume flows, pressures, temperatures, concentrations, etc., and which also necessitates, among other things, the frequency control of a detergent feed pump.
  • the cover 3 is connected to the upper portion of the open container, preferably welded along a weld 5, which ensures easy mounting and retrofitting of existing containers. Not only the cover 3, but also the conduit member 2, is stationary mounted on the open container.
  • the device of Fig. 1 comprising a conduit member 2 and a cover arranged in the upper region of the inside of the container wall 1 3.
  • the cross section of the conduit member 2 forms other than can take on a round shape. In the context of the invention, however, round is preferred because thus starting from a central axis 6 of the conduit element, the cleaning agent can be applied to the container wall 1 at a fixed angle.
  • the application of the cleaning agent is done via at least one row of holes 7, 8 in the conduit element 2, with the arrangement or the position of at least one row of holes 7, 8, starting from the central axis 6 of the conduit element 2, the angle is given, with which the cleaning agent of low Distance to meet the inside of the container wall 1.
  • two rows of holes 7, 8 are preferred, which run essentially parallel to the central axis 6 of the conduit element 2 and, as shown in FIG. 3, may optionally be arranged offset to one another.
  • the openings of the rows of holes 7, 8 can be brought in an already known manner in the conduit element 2.
  • the openings are drilled, wherein the diameter of the holes in the range of about 1mm to 2.5mm and the distance between the holes within a row of holes 7, 8 35mm.
  • the distance of the openings within a row of holes 7, 8 is due to the opening diameter and the volume flow and therefore can vary.
  • the openings of the row of holes 7 are arranged starting from the central axis 6 of the conduit element 2 substantially parallel to the inside of the container wall 1, i. in a plane extending through the central axis 6 parallel to the container inner wall 1.
  • the tangential plane if it is arranged as shown in Fig. 2 can be seen on the upper side of the conduit element 2, the cleaning of the cover 3 is made.
  • the openings of the row of holes 7, starting from the central axis 6 of the conduit element 2 perpendicular to the cross-sectional plane of Container arranged.
  • this arrangement is not a prerequisite for the use of the device according to the invention.
  • the openings of the row of holes 8 starting from the central axis 6 of the conduit member 2 at an obtuse angle, preferably from 46 ⁇ to 89 ⁇ , in particular from 60 ⁇ to 85 ⁇ , more preferably about 80 ⁇ , arranged to the inside of the container wall 1.
  • the effective cleaning of the container is performed, with their angle arrangement in the above range can be selected so that the cleaning agent hits targeted in the region of adhering to the inside of the container wall 1 pollution.
  • the partial flows of the cleaning agent after hitting the container wall 1 should have a predetermined directional tendency running in the direction of the container bottom, they should be distributed substantially uniformly in all directions in their lateral flow progressions. Therefore, the openings of the row of holes 8 are arranged in the embodiment shown, starting from the central axis 6 of the conduit element 2 in a plane which extends both perpendicular to the container wall 1 and to the cross-sectional plane of the container.
  • FIG. 4 the device according to the invention is shown around the entire circumference of an upwardly open and round container forming a closed cleaning ring.
  • This cleaning ring consists of a continuous cover 3 and two ring-segment-shaped line elements. 2
  • the cleaning agent is applied from the two stationary conduit elements 2 on the inside of the container wall 1, wherein the Line elements 2 can also be applied successively with detergent.
  • the cleaning is thus alternately flows through once a ring-segment-shaped line element 2 and then the other with cleaning liquid from the detergent feed line 3.
  • the inside of the container wall 1 is wetted and solved by the mechanical and chemical energy of the cleaning agent jet adhering to the container wall 1 pollution.
  • the mutual Beschwaung the inside of the container wall 1 leads to high specific volume flows in the pollution area while extending the contact time between detergent and dirt particles.
  • gases in the container can be sucked into the at least one conduit element 2 and removed therefrom.
  • gases e.g. Fermentation gases in the fermentation of wort
  • This negative pressure causes a suction on occurring gases, which can then be sucked into the conduit element 2 and removed from the process.
  • gases can be dissipated directly at the place of origin, which counteracts a costly circulation or exchange of ambient air with the associated costs with advantage.
  • the at least one line element 2 is connected to a supply line and / or a drain, which is why the openings of the rows of holes 7, 8 both for a flow direction emerging from the conduit element 2 and for a flow direction of fluids entering the conduit element 2 or gases are used.
  • At least one line element 2 adapted to the contour of the container opening is arranged with at least one row of holes 7, 8. Since the at least one line element 2 can be controlled with a defined cleaning program is the automation of cleaning associated with a simple visual controllability.
  • the cleaning agent is applied from a small distance from the at least one conduit element 2 on the inside of the container wall 1, wherein the rebounding from the container wall 1 in the direction of the container opening, possibly dirt particles having cleaning agent is deflected by a cover 3 in the direction of the container bottom and the Conduit 2 facing side of the cover 3 is cleaned by means of emerging from the conduit element 2 detergent.
