- the present invention relates to a liquid applicator for applying liquid to a material cake transported on a conveyor.
- liquid application systems find, for example, as humidification, preferably for continuously operating presses, in particular for the production of material plates, application.
- the invention further relates to a method for applying liquid to a material cake.
- Such moistening has the disadvantage that a metering of the moistening agent due to the application of the moistening agent in the vaporous state is only possible in a very inaccurate manner.
- exposure to steam is generally associated with relatively high losses of humectant.
- the vaporization also leads to condensation on the machine parts, wherein the condensed moistening agent can then drip onto the material cake. This can affect the pressed plate optically or lead to procedural disadvantages.
- Another object of the present invention is to provide a method which enables a corresponding application of the liquid.
- the liquid application system according to the invention for applying liquid to a material cake transported on a conveyor device has a first liquid application device.
- the conveying device has a porous section, on which the material cake rests or against which the material cake rests and which is permeable to a liquid to be applied.
- the liquid application device further comprises an application device, via which the liquid to be applied can be applied, preferably sprayable, in the liquid state to the side of the porous section of the conveying device which faces away from the material cake.
- the liquid application device further has an overpressure chamber in which there is a first overpressure relative to the environment, the porous section of the conveying device being guided past the overpressure chamber and the applied liquid being transportable via the first overpressure through the porous section of the conveying device or by the first overpressure is held at the porous portion.
- the liquid is first applied to the porous section of the conveying device and is pressed through the pores formed in the porous section by means of the overpressure and thus reaches the material cake or prevents dripping of the liquid.
- the liquid is also applied against the force of gravity on the underside of the material cake, wherein the material cake can be transported due to the conveyor device in an advantageous manner.
- the prevailing in the pressure chamber first overpressure generates an air flow which acts on the liquid or this entrains and thus transported through the porous portion of the conveyor.
- the overpressure can also be dimensioned such that the liquid is initially held only in the porous section of the conveying device and is transported through it in a subsequent process step.
- the first overpressure is chosen such that the force acting on the liquid gravity, prevailing in the pores of the porous portion capillary resistance and a flow resistance is overcome, so that the liquid is transported through the pores of the porous portion and facing the conveyor Side of the material cake.

- the high pressure chamber has a cover with a plurality of openings, wherein the porous portion of the conveyor sealingly abuts the cover.
- the sealing abutment of the porous portion on the cover prevents an air flow resulting from the excess pressure from escaping laterally from the porous portion.
- the provision of the plurality of openings in the cover ensures that the overpressure only acts on the porous section or material cake at some points, so that a lifting of the material cake caused by the second overpressure from the conveyor device or the porous section of the conveyor device is prevented by the cover of the high pressure chamber.
