Definitions
- the invention relates to a device for cleaning plants for the production and / or processing of foods or pharmaceuticals with at least one cleaning unit.
- the invention is therefore based on the object of providing a simple and maintenance-friendly cleaning system which also meets high hygiene requirements, such as those which are placed, for example, in the production and / or processing of foods or pharmaceuticals.
- the object is achieved in that the cleaning unit, which can be supplied with a cleaning agent via a flexible connection, is designed to be movable by the system to be cleaned.
- cleaning agent is to be understood here to mean all agents to which a cleaning effect can be attributed, in particular water, water / detergent mixtures or solutions, foam and also gases and gas mixtures (e.g. air).
- the foam mentioned is usually generated from water and detergent with the addition of gas (e.g. nitrogen).
- the cleaning unit preferably has at least one nozzle for dispensing cleaning agent.
- the cleaning unit particularly preferably has at least one nozzle head for dispensing cleaning agent, in particular a nozzle head which executes a rotational movement driven by the flow of the cleaning agent.
- An angular coverage of 360 ° is advantageously achieved by the rotational movement.
- swiveling nozzle heads can also be used.
- the cleaning unit particularly advantageously has a means of transport.
- the means of transport is preferably designed as a carriage.
- a guide system in particular at least one guide rail, is particularly preferably provided for guiding the transport means.
- the carriage advantageously has wheels which are guided by the guide rail. This makes it possible to move the carriage with little friction loss.
- Such a carriage is usually also referred to as a trolley.
- two parallel guide rails are provided for the slide.
- a parking position is provided for the transport means in the interior of the system, at which the transport means is parked during the production and / or processing of food or pharmaceuticals.
- the means of transport can remain in the hygienic environment and does not have to go into the before the start of a cleaning phase Plant are introduced. Likewise, all connections can remain connected to the cleaning unit. The cleaning unit can therefore be used immediately at any time.
- a drive is expediently provided for moving the cleaning unit, in particular a drive mounted outside the system to be cleaned, which drive is connected to the cleaning unit via a force transmission element.
- An electric drive is advantageously provided.
- a pneumatic or hydraulic drive is also suitable.
- a chain is preferably provided as the force transmission element, in particular a lubrication-free stainless steel chain.
- the use of a lubrication-free stainless steel chain is particularly suitable for systems with very high hygiene requirements.
- a belt or, for example, plastic-coated wire rope is provided as the force transmission element.
- a hose in particular a flexible plastic hose, is advantageously provided as a flexible connection.
- the cleaning unit is connected to a source of cleaning agent by means of the flexible connection.
- a means for changing the length of the flexible connection available inside the system to be cleaned is provided for adapting the flexible connection to the movement of the cleaning unit.
- a roller is preferably provided which is connected to a drive.
- the roller is particularly preferably designed to be axially movable.
- the roller is expediently subjected to a forced movement in the axial direction.
- An advantageous forced movement has the effect that the flexible connection, for example a hose, comes to rest next to the previous winding with each revolution of the roll. This makes it possible to wind or unwind a constant length of hose with each revolution of the roll.
- This configuration has the particular advantage that the synchronization of the Speed of rotation of the roller is significantly simplified with the speed of movement of the cleaning unit.
- the roller is mounted as a thread, in particular as a trapezoidal thread, in particular as a multi-start trapezoidal thread, and a second bearing of the roller is designed as a torsionally rigid sliding bearing.
- the pitch of the trapezoidal thread is appropriately matched to the diameter of the flexible connection or the hose. The required thread pitch increases with increasing hose diameter.
- a ball thread is also suitable.
- a shaft suitable for the passage of cleaning agents is provided for the roller.
- the cleaning agent flows through the interior of the shaft, which is advantageously designed as a hollow body.
- exactly one drive is provided for driving the roller and for moving the cleaning unit.
- the movement of the cleaning unit and the roller are advantageously automatically synchronized.
- the flexible connection is thus always wound up or unwound in accordance with the current position of the cleaning unit in the system to be cleaned.
- Cleaning shadows can be avoided by moving the cleaning unit.
- the movement of the cleaning unit produces an advantageous effect as would be achieved by an infinitely large number of cleaning nozzles installed next to one another.
- a suitable choice of the nozzle head for example in the case of a rotating nozzle head with several nozzles arranged at different angles to the axis of rotation, very thorough cleaning without cleaning shadows can be achieved without problems.
- the cleaning unit itself and the guide system are also included, ie these components are also automatically thoroughly cleaned with the device according to the invention.
- the investment costs for the cleaning components increase only insignificantly for large systems, since the price of the movable cleaning unit remains the same regardless of the spatial extent of the system to be cleaned, at most the length of the flexible connection required to supply the cleaning unit with cleaning agent, as well as the length of the power transmission element (eg chain) increases with the spatial expansion of the system.
- these components cause comparatively low investment costs.
- investment costs are significantly reduced compared to conventional cleaning systems.
- the device according to the invention has an advantageously low need for operating resources such as water and detergent with an excellent cleaning result.
- Figure 1 shows a cross section through a plant for the treatment of food such as a continuous plant for freezing food with a cleaning unit according to the invention
- Figure 2 is a plan view of the interior of such a system.
- FIG. 1 shows a continuous system for freezing food (e.g. a freezer tunnel) with a cleaning unit 5 according to the invention.
- the system has a conveyor belt 1 on which the food is transported in the freezer mode and on which the highest level of contamination therefore occurs.
- the system Above the conveyor belt 1, the system has two guide rails 10 on the left and right along the side wall, along which the cleaning unit 5 can be moved.
- the cleaning unit 5 has a carriage 7 as a means of transport 7, on which a nozzle head 6 is fastened, which is caused to rotate by the flow of the cleaning agent supplied via a hose 8.
- the flexible connection 8 designed as a hose 8 (for example made of plastic) is on a roll 9 wound up according to the invention and connects the cleaning unit 5 to a source of cleaning agent (not shown).
- FIG. 1 shows an entry system 4 for refrigerants (for example deep cold nitrogen) which is attached to the ceiling of the system, as well as fans 2 also attached to the ceiling for circulating the atmosphere in the system in freezing mode, and a baffle third
- refrigerants for example deep cold nitrogen
- the cleaning unit 5 is moved back and forth at least once on the path that is predetermined by the guide rails 10, the cleaning agent emerging from the rotating nozzle head 6 and the inside of the system being freed of impurities.
- An angular coverage of 360 ° is advantageously achieved by the rotational movement.
- a rotating nozzle head 6 with a plurality of nozzles arranged at different angles to the axis of rotation is provided with particular advantage, which enables thorough cleaning without cleaning shadows.
- the cleaning unit 5 Due to the arrangement of the components relative to one another shown in the two figures, the cleaning unit 5, the guide rails 10 and the chain (not shown) for transmitting the driving force to the cleaning unit 5 are also cleaned simultaneously with the cleaning of the system.
- the cleaning unit 5 After cleaning has been completed and during the freezing operation in the system, the cleaning unit 5 is accommodated in the parking position shown in FIG. 1.
- the parking position is also characterized by a sheet 11 attached to the walls of the system under the cleaning unit 5.
- the sheet is advantageously inclined and / or bent in such a way that the cleaning unit 5 is shielded from the conveyor belt 1, especially with a view to reliably preventing any dripping agent that may remain on the cleaning unit 5 after cleaning onto the introduced food.
- the cleaning unit 5 may be advantageous to park the cleaning unit 5 outside the system if there is very little space inside the system. In both cases, once the cleaning is complete, the entire space in the area of the conveyor belt 1 is advantageously available for the freezer operation and in particular for the foodstuffs to be frozen.
- FIG. 2 shows in detail a plan view of the interior of the system described with the guide rails 10, the slide 7 with wheels 17, which represent the guide connection between the guide rails 10 and the slide, and the nozzle head 6, which is fastened on the slide 7 and together with this forms the cleaning unit 5.
- the nozzle head 6 is connected via the flexible connection 8 (e.g. as a (plastic) hose 8) via a supply line 16 for cleaning agents to a source for cleaning agents.
- the hose 8 is guided over a roller 9, which is seated on a shaft 14, and a threaded bearing 13 and a torsionally rigid sliding bearing (not shown in detail) on the side of the motor 15, which serves to drive the roller 9.
- the bearing 13 designed as a thread is provided as a multi-start trapezoidal thread with a large pitch.
- the torsionally stiff sliding bearing has a feather key.
- a rotary feedthrough 12 is available for the trapezoidal thread 13 and is connected to the housing of the system.
- the roller 9 is expediently subjected to a forced movement in the axial direction.
- An advantageous forced movement causes the hose 8 to lie next to the previous winding with each revolution of the roller 9. This makes it possible to wind up or unwind a constant length of hose 8 with each revolution of the roll.
- This configuration has the particular advantage that the synchronization of the rotational speed of the roller 9 with the speed of the movement of the cleaning unit 5 is considerably simplified.
- a control which ensures that the hose 8 remains essentially open during the entire cleaning process the shortest way connects the roller 9 with the cleaning unit 5.
- the control system matches the two drives, of which only the motor 15 is shown in FIG. 2.
- the position of the cleaning unit 5 is determined by automatically counting the chain links of the power transmission element and the rotational speed of the roller 9 is controlled in accordance with the result.
- the speed of rotation is changed in accordance with the area in which the cleaning unit 5 is moving, since the speed of the cleaning unit 5 also changes: in the vicinity of the front (parking position) and rear turning point, it is generally lower than in the middle of the distance to be covered Route.
- the two movements described are synchronized in that exactly one drive is provided for driving the roller and for moving the cleaning unit.
