Definitions
- the invention relates to a method for cleaning a liquid, in particular oil, which is used in a bath of a deep fryer, by means of a filter element through which the liquid flows, and a device for this.
- Such a device for cleaning liquids, in particular cooking oils, by means of a filter in a filter housing is known from WO 02/28505, the filter being connected downstream of a pump, and a motor for driving the pump being provided in a housing, which has a Rotor with a rotor disk with blades in a diving housing.
- the housing, immersion housing and filter housing together form a unit that can be at least partially inserted into and removed from the liquid to be cleaned.
- the object of the present invention is to develop a method and a device of the above-mentioned type, which can be used in a variety of ways and, above all, in machines that are already on the market.
- the liquid is preferably removed from the deep fryer during operation, passed through the filter element and brought back into the bath.
- the method according to the invention thus ensures continuous cleaning of the liquid even when a deep fryer is in operation, for example.
- discontinuous operation is also possible and should be included in the inventive concept.
- the only important thing is that the one to be cleaned Liquid is removed from the liquid bath, cleaned and returned to the bath.
- the liquid to be cleaned is thus removed from the bath, pushed through the filter element from below and led back into the bath.
- the return should preferably take place via a nozzle with which as many areas of the bath as possible can be flowed into, so that no dead spaces are formed there in which contaminants can settle. To ensure this, it can even be considered that the nozzle is moved, which can be done in a fluid manner or, for example, by a motor.
- the bath should be provided with a liquid circuit for the liquid from the bath and back into the bath be assigned, the filter element being switched on in the liquid circuit.
- This filter element is preferably located in a removable filter box, so that this filter element can be easily replaced.
- the filter box can also be easily cleaned in this way.
- the filter element preferably divides the filter box into a lower and an upper space, both of which may be separated from the filter element by any separating element, in particular, for example, by a perforated plate.
- the lower space should be connected to a pump, which is also connected to the liquid circuit.
- the piece of pipe described above which is connected to the drain of the bathroom, flows into this pump.
- the pump then presses the liquid into the lower space of the filter box, i.e. under the filter.
- a return line for the liquid leads from the upper space of the filter box back into the bath, with this return line preferably passing through the pipe section.
- the return line opens out of the pipe section into the bath with a trunk, the nozzle mentioned above being provided in the trunk.
- Figure 1 is a front view of the device according to the invention for cleaning a liquid
- Figure 2 is a perspective view of the device according to Figure 1;
- Figure 3 shows a further perspective view of the device according to Figure 2 from the side from below;
- Figure 4 is a side view of a large part of the device according to Figure 1;
- Figure 5 is a side view of a schematically illustrated, partially opened filter box
- Figure 6 is a schematic and block diagram representation of the method according to the invention for cleaning a liquid.
- a device according to the invention for cleaning a liquid has an insert 1 with a bath 3, which is inserted into a housing 2.
- This housing 2 is preferably open at the front, but can of course also be closed.
- FIG 2 there is a liquid 4 shown in Figure 5 in the bath 3.
- Heating elements 5 are immersed in the bath 3 to heat the liquid 4.
- These heating elements 5 are assigned a folding device 6 for folding out the heating elements 5 from the bathroom 3.
- the liquid 4 is a corresponding frying oil.
- a drain 9 is provided, into which a liquid circuit 30 according to the invention is inserted.
- This drain 9 leads into a pipe section 10, which in turn is connected to a pump 12 via an elbow 11.
- a ball valve is inserted into the manifold 11 and can be operated by means of a lever 13. This ball valve 13 is neglected in Figure 4.
- the pump 12 is followed by a filter box 14.
- This filter box 14 has an upper frame 15, which is connected to a machine-fixed frame 17 via clamping elements 16. A corresponding seal is arranged between them. After loosening the clamping elements 16, the filter box 14 can be removed from the frame 15 and the contents of the filter box 14 can be cleaned or replaced.
- the filter box 14 with its handle 15 can be seen more clearly, with a zigzag filter element 19 dividing a lower space 20 from an upper space 21 of the filter box.
- the zigzag filter element 19 overlaps a corresponding grid 22 and is fixed on this grid 22.
- a pipe arrangement 23 leads back into the pipe section 10 and continues in the pipe section 10 with a trunk 24, which opens out of the drain 9 and has a nozzle 25 there.
- a further ball valve with a lever 26 is also switched into the pipe arrangement 23.
- the liquid circuit 30 Due to the design of the bath 3 with the lower area 8, it is possible to use the liquid circuit 30 according to the invention when operating the device itself, i.e. with the heating elements 5 folded in and the basket 7 inserted during deep-frying.
- the idea of the invention also includes that the liquid circuit 30 is operated outside of the activity of the device.
- the possibility of subsequently inserting the liquid circuit 30 into existing devices or baths 3 by simply designing the pipe section 10 at its free end with an annular collar, with this pipe section 10 being inserted between the annular collar and the bottom of the bath 3 a corresponding seal is inserted.
- the ball valve is opened with the lever 13 so that liquid can be removed from the bath 3 by the pump 12.
- the pump 12 presses this liquid into the lower space 20 of the filter box 14 under the filter element 19 and pushes it through the filter element 19 from below.
- a perforated plate 27 can be provided below the grid 22.
- a further perforated plate 28 or the like can also be provided towards the upper space 21, which delimits this upper space 21 from the filter element 19.
- the liquid After the cleaned liquid has entered the upper space 21, the liquid enters the pipe arrangement 23 and from there through the opened ball valve with the lever 26 into the trunk 24 in the pipe section 10 and is discharged from the trunk 24 through the nozzle 25 into the bath 3 deployed.
- This nozzle 25 can, for example, be equipped separately or aligned so that no dead zones arise in the bath 3 in which impurities in the liquid can accumulate.
- the nozzle 25 is moved by a suitable device or as a result of the liquid itself flowing through, so that it variably covers different zones of the bath 3.
- the filter box 14 After a predetermined time or at regular intervals, the filter box 14 is removed after closing the ball valves by loosening the clamping elements 16, cleaned and/or the corresponding filter is replaced.
- an additional trough 28 is inserted under the liquid circuit 30, which serves to collect any oil that may emerge from the liquid circuit 30. However, appropriate seals should prevent this.
