Definitions

  • the present invention relates to a method of cleaning a mixed oven for cooking food products by providing "dry and / or steam" cooking modes.
  • such a mixed cooking oven mainly comprises a muffle defining the enclosure inside which the food products are cooked by a heat source (gas, electricity), and a boiler containing water. and entraining it, in the form of steam, in the muffle.
  • a heat source gas, electricity
  • washing-degreasing / rinsing for the muffle cooking chamber can be introduced in the form of tablets, degradable powder pods or in the form of liquid product. After the washing-degreasing of the muffle, to treat greasy and other deposits, it is descaling it and the boiler to treat limescale and other deposits by the introduction of tablets or specific liquid products to dissolve the deposits. limescale deposits and other similar residues.
  • the present invention aims to overcome these disadvantages.
  • the method of the invention for cleaning a mixed cooking oven comprising at least one muffle forming the cooking chamber of the oven and a boiler for sending the water, in the form of steam, to the interior of the muffle enclosure, is remarkable by the fact that one performs in parallel, so concomitant, the muffle washing step and the descaling step of the boiler.
  • combi oven comprises a muffle and a boiler and therefore four steps (washing and descaling) must be applicable to these two bodies for a complete cleaning.
  • a first elimination could consist in keeping only two concomitant maximum steps, so that only two solutions would have remained.
  • the combi oven 1 shown schematically and symbolically, on the figure 1 , is intended to cook food products in dry, steam or combined cooking modes (dryer + steam) and, for this, it comprises a muffle 2 defining the cooking chamber of the food products and a boiler 3 containing water and adapted to be placed in communication, via a connection 4, with the enclosure of the muffle during steam or mixed cooking.
  • a pump 5 is connected by a connection 6 to the muffle 2 for feeding, from an upstream storage tank, not shown, a washing-degreasing product into the enclosure of the muffle 2.
  • a pump 7 is connected, by a connection 8, at the boiler 3 for bringing, from an upstream storage tank, not shown, a descaling product into the boiler 3, and a pump 9 is connected, via a connection 10, to the muffle 2 for feeding from an upstream storage tank , not shown, a descaling product in the enclosure muffle 2.
  • the storage tank for descaling the muffle may be the same as that required for the boiler.
  • a programmable central unit 11 associated with the oven 1 manages, in addition to the various cooking modes, temperatures, times, etc., the cleaning cycles of the muffle and the boiler according to various parameters or time-related instructions. use thereof, the size of the furnace, the flow of water, the consumption, the hardness of the water, etc ... and it determines, consequently, the operation of the pumps and other associated organs ( solenoid valves, ...) by a link 12 symbolizing the various information exchanged (inputs-outputs) between the unit and the pumps, the muffle and the boiler.
  • the cleaning process is carried out as shown in FIG. figure 2 .
  • the method consists in carrying out in parallel the washing of the muffle 2 and the descaling of the boiler 3.
  • the pumps 5 and 7 are controlled and send the washing and descaling products, according to the predetermined desired quantities, depending on the state of fouling and descaling noted, in the enclosure muffle and in the boiler, respectively.
  • a logic gate 13 confirms that the muffle is at a good temperature to start the cycle.
  • the washing of the muffle LM consists of a prewashing step 15 followed by a step of heating the water with the introduction of the washing product 16 by the pump 5. Then, after the washing step 14, a pre-rinsing step 17 is provided to finish the washing of the LM muffle and best evacuate the deposits and products and washing water used contained in the enclosure muffle 2.
  • a step 21 composed successively of a neutralization, a drain and a rinsing of the descaled boiler 3.
  • a logic gate 22 either the DM muffle is descaled, or the muffle RM is rinsed. This alternative is lifted according to the scaling of the muffle 2 which, as previously stated, is less common than that of the boiler.
  • the method of the invention provides successively a step water heating 23 then admitted into the muffle 2, followed by a clean descaling step 24 triggered by the pump 9, then a neutralization step - draining - rinsing 25.
  • the steps like the other d elsewhere, are handled automatically by the unit, but can be triggered manually, if necessary. Then, the cleaning cycle is continued by rinsing the descaled muffle RM.
  • the muffle RM is directly rinsed by a step of heating the water 26 followed by a rinsing step 27,
  • the melt RM After rinsing the melt RM, the latter is dried by a final drying step 28, if this is necessary via a yes-no logic gate 29.
  • the oven cleaning cycle 1 is then completed and symbolized on the figure 2 by the rectangle 30 displayed, for example, on the oven 1.
  • the process of the invention reduces the cleaning time of the oven and, therefore, its immobilization, by integrating in parallel the descaling of the boiler and the washing of the muffle, treating them at the same time, but separately and automatically by the unit, according to the degree of scaling of the oven determined by the aforementioned parameters. And only if necessary, the muffle is descaled. The degree of scaling is done separately (boiler and enclosure) to judge the relevance of descaling, descale only the boiler (or muffle) or descale both.
  • the user therefore has a real knowledge of the situation in the presence, the process allowing a reduction of the intervention times and, moreover, an optimized water consumption by the descaling and rinsing associated.
