Definitions
- the invention relates to a device for heat treatment of substances, especially food, with a cooking space surrounded by a housing, one through a separating plate separated from the cooking space, but in terms of flow Blower room connected to one another via gap openings Air circulation fan, a device for generating a steam-containing treatment medium in the cooking space, a condensation device for condensing excess Steam and shut-off devices in all of the cooking space lines leading to the outside.
- a device of this type is known from DE 196 49 452 A1.
- the object of the invention is a device of the beginning explained type so that condensation large amounts of steam quickly return the dried Air without disturbing the mixed condensation the device process is enabled.
- This task is the device in the preamble of claim 1 specified type according to the invention solved that the condensation device as a mixed condensation device based on the pressure range of the recirculation fan is formed extending into the cooking space.
- An advantageous development of the invention consists in that for the mixed condensation at least one injector nozzle is provided, which is in the immediate pressure range of the Circulating air blower is located and the direction of the jet essentially in the direction of flow of the treatment medium is aligned. Since it is for water injection provided injector nozzle or the injector nozzles in the immediate vicinity Pressure range of the circulating air fan, that will Steam-air mixture from which the steam component condenses should be in intimate connection with the sprayed Water due to the pressure of the forced air fan brought. The immediate proximity of this injector nozzle to the Recirculation fan is for the mixing process between steam and injected water extremely beneficial.
- Injector nozzle or injector nozzles on the gap passage of the divider opposite wall of the blower room with spray direction on the gap at the bottom of the Partition plate is arranged, so is an adequate mixing room created in which the condensation takes place can, so after passing through the gaseous mixture below of the divider already dried and from Steam-free air is present, which then goes directly into the cooking space can occur, this process then still in the condensation device open to the top of the cooking space continues.
- the cooking space floor in the area the injector nozzle or injector nozzles one from the pressure range out of the blower compartment and into the cooking compartment has channel-like depression, the bottom of which towards Cooking chamber is inclined and that the injector nozzle or injector nozzles at the pressure range assigned to the recirculation fan End face of the channel-like recess is arranged or are.
- This channel-like depression can correspond to the Needs to be designed in the breadth and depth to create a sufficient condensation space, whereby additional lines outside can be avoided.
- width of the recess is approximately 20 to 25% of the width of the base of the device equivalent.
- Cooking chamber an inlet line monitored by a vacuum valve for ambient air, it is achieved that Ambient air flows into the cooking space when through the Condensation of the vapors creates a negative pressure. hereby it is guaranteed that only those that are removed for dehumidification Amount of vapor is replaced by fresh ambient air. Due to the inventive limitation of the supplied Ambient air, according to the volume decrease of the brothers, it is achieved that only the absolutely necessary Brothers replacement takes place, so that only the absolutely necessary Fresh air supplied must be heated, which affects the energy balance favorably influenced. A can be used as a vacuum valve simple cheap spring loaded vacuum valve used become.
- a cooking chamber 2 is also provided, in which these substances are placed for treatment become.
- a blower chamber 4 is through a partition plate 3 separated, in which a circulating air blower 5 is provided, that can be driven by a motor 6.
- the fan is surrounded by a heater 7 for heating the treatment medium serves which has a central opening 8 is sucked out of the cooking space into the blower compartment.
- the Partition plate 3 has side slots, not shown gap openings at its upper and lower edges 9 and 10, over which the treatment medium after heating by heating 7 back into cooking space 2 is transported into it.
- a channel-like recess 12 is provided starting from the pressure area 13 of the blower chamber 4 in extends the cooking space and is inclined towards the cooking space.
- a device drain 14 provided at the deepest point of this channel-like depression.
- an injector nozzle 16 is arranged, the cold water in the direction the arrows 17 sprayed into the channel-like recess 12 essentially with direct current with the through the Arrows 18 indicated flow of the treatment medium.
- the water accumulated in this mixed condensation runs on End of the channel-like recess 12 on the bottom 19 thereof
- Device drain 14 which opens into a siffon 20, the drain pipe is designated by 21. With 22 an exhaust pipe is designated.
- the space is within the recess 12 as a condensation pan with the reference symbol 23 designated by a splash guard 24 in the form of a sheet can be covered.
- This splash guard can also be used Openings should be provided so that the condensation from Steam frees air into the cooking space in this area 2 can escape.
- a vacuum valve 25 Inlet line 26 provided to allow ambient air to flow into the cooking space 2 to leave if there is a negative pressure in this a condensation effect occurs in the upper area of the Cooking chamber monitored by a vacuum valve 25 Inlet line 26 provided.
