  • Page 11: Open Valve Operation

    2.1. Open valve operation The rotation of the fan creates a vacuum effect in the local area behind his disk back where it faces the suction pipe/exhaust 5. When the butterfly valve 7 is open to this effect a vacuum sucking air flow entering through the pipe 5. Simultaneously the moist air inside the cooking chamber is induced to leave through the vent tube 6, aided by a flow diverter (not shown) placed inside the chamber at the exit hole.

  • Page 12: Closed Valve Operation

    2.2. Closed valve operation With the valve closed, the steam can’t escape from the vent pipe 6, or from the tube 5 at least until the pressure inside the cooking chamber is not sufficient to overcome the effect of decompression generated by the rotation of the fan (usually 1,5-2,0mBar). But when the pressure chamber exceeds the decompression generated by the fan, the steam excess is expelled through the tube 5.
  • Page 13 The two modes of operation described above are used in different modes of cooking in the following way: Convection cooking: means the user can determine the % the vent valve is open according to the diagram below. 0%: vent completely open (bar on the display all red) from to 90%: the valve opens and closes in timed mode, the value shown on the display is the % of time that remains closed.

    4.1.2. Power schemes As it is evident from the diagram above, in the pre-mixed system air and gas are sucked in and mixed together by a fan. It is possible control the quantity of the air-gas mix because the fan rotation speed is electronically controlled, to obtain a variation of gas flow and thus the power of the burner.

Functional Diagram of Washing circuit In general, the washing cycle has the following stages: 1 – initial rinsing 2 – detergent sprinkling 3 – intermediate rinsing 4 – sanitizer sprinkling 5 - final rinsing 6 - drying All these stages are separated by operating at low temperature with steam to soften the fat in the cooking chamber.
  • Page 83 In the more intensive cleaning programs, the dosing of the cleaning products is repeated several times depending on the program. Available cleaning programs: The detergent and sanitizing distribution is made as follows: • Product load. The pump sends the chemicals into the empty tank, this phase takes a few minutes.
  • Page 84 Rinsing is accomplished by operating the solenoid water for several minutes. The water circulates through the tank and the dispensing circuit, and finally is distributed in the chamber through the sprinklers. The circuit is also fitted the following safety: • Water pressure switch: it is downstream of the solenoid water and detects the presence of pressure in all the phases in which the water valve is open (or supply rinsing detergent / sanitizer).

    5.2. Components and functioning of BX washing system 1st and 2nd gen. In the 1st and 2nd generation ovens, the operation of the system works in this way: the oven automatically heats and keeps at the most suitable temperature for the softening of the cooking residues, but the application of the washing product and rinsing must be done manually by the operator when CLE and H2O appears on the display.
  • Page 94 The operation of the circuit is similar to the FM: the oven is running automatically heated and holding the temperature most suitable for washing and rinsing, while the application of the chemicals must be done manually by the operator when the display shows the CLE. The automatic rinsing is made simultaneously by opening the solenoid valves for rinsing and steam production.
