DESCRIPTION:
BRIEF SUMMARY
The invention relates to a frying apparatus, in particular for grilling, including an electric heating device with a contact frying surface.
In conventional ovens not using a contact frying surface, as disclosed e.g. in DK-A-10540 it is well known in general to provide means for conditioning the oven atmosphere by heating and producing a desired air circulation.
The grilling of meat and fish products by means of electric heat sources may either be effected in a closed oven by means of an electric radiant heat element which from above irradiates the meat or fish product placed on a grid or grill pan by simultaneous ventilation of the interior of the oven, or by means of an open grilling apparatus, the meat or fish product being then placed in contact with an underlying frying surface generally profiled with raised ribs to provide the same effect as obtained by a conventional grill.
Open grills are known both in small-size designs as table grills for domestic use as well as in largersize designs, e.g. for use in restaurant kitchens. In such open grills water vapour, fatty particles, smoke and smell generated during grilling will be given off directly to the environments so that the frying process when taking place indoor must generally be effected under a cooker hood having a high induced draught and filtering capacity.
On this background it is an object of the invention to provide an electric frying apparatus, particularly fitted for grilling, by which grilling may be effected indoor while maintaining the desired properties characteristic of said form of frying, substantially without giving off vapour, fatty particles, smoke and annoying smell to the environments.
This is obtained according to the invention by a frying apparatus of the referenced type in that the heating device with the contact frying surface is positioned in a mainly box-shaped cabinet with an upturned opening that may be closed at a distance above the contact frying surface by a preferably transparent cover plate, an air exhaust being positioned at one lateral wall of the cabinet conditioning means being provided in connection with the cabinet for conditioning means being provided in connection with the cabinet for conditioning the atmosphere between the contact frying surface and the cover plate, by provision of an air flow passing substantially horizontally across the contact frying surface towards the air exhaust when the cover plate is mounted, means being provided for controlling the temperature and the amount of air of said air flow to produce temperature and air humidity conditions suitable for a specific frying operation, and means being provided at the air exhaust for the removal of vapour, fatty particles, smoke and smell from said atmosphere.
The frying apparatus according to the invention thus fulfills the conditions necessary to obtain optimum grilling as regards temperature and air humidity in a closed atmosphere from which vapour, fatty particles, smoke and smell may be removed through an appropriate air exhaust.
Even though the invention particularly has grilling for its object it is not restricted thereto, the frying apparatus being as well applicable for other forms of frying, such as so-called deep-frying, by regulation of the conditioning to the desired temperature and humidity conditions.
If it is possible on the site of installation of the frying apparatus to connect the air exhaust with a suitably dimensioned air exhaust passage discharging into the open air, the conditioning air flow may incidentally be provided by natural draught and reasonably good frying results can be obtained without further precautions.
In connection with the air exhaust it is, however, preferred to arrange a filtering device in connection with the air exhaust for the removal of vapour, fatty particles, smoke and smell.
In places where it is not possible to establish a correctly dimensioned air exhaust passage to the open air it is, moreover, preferred that the conditioning means include a fan mounted in connection with an air intake in one l
