Abstract

Carmelising iron of the type including a heating element secured to a handle and connected to an electrical power source by a cord, characterised in that the heating element is a cast-iron block 3 in which a heating wire 5, wound up into a spiral, is embedded in a refractory material, in that the said block is removably mounted on a plate 2 integral with a hollow handle 1 equipped with a grip 7 which is also removable, and in that the strands of the heating wire extend inside the handle 1 as far as the grip where they are connected to the power cord wires 6 via rapid connection means.

Description

CARAKELIZER IRON
The invention relates to culinary appliances known as caramelizing iron and which are used to caramelize culinary preparations.

 The caramelization technique consists in locally applying strong heat to the surface of a culinary preparation, - generally a cake, avoiding as much as possible this heat being transmitted inside the preparation so as not to anneal it .

 For this, the surface of the preparation is subjected to a heat of around 6 ° C. or more for a very short time of the order of a few seconds.

 It is a manual operation 'carried out by craftsmen using instruments which can be either simple heat accumulating plates mounted on a handle usually called polka irons, or armored heating resistors supplied with electricity and also mounted on a handle. These resistors may or may not be provided with a welded plate attached to the resistance to homogenize the heat radiation. These resistances are generally called caramelizing iron.

 The disadvantages of polka irons are that they are heavy to handle and require constant reheating.

 Armored resistance caramelizing irons are also heavy to handle, they are also fragile and expensive, they consume a lot of electrical energy (about i watts watts) and have a very poor energy efficiency. Indeed, given their design (heating element embedded in magnesia inside a stainless steel tube) the shielded resistors have a high thermal inertia therefore a slow rise in temperature.

 The present invention aims to provide a new type of caramelizing iron much lighter than previously known irons, therefore more manageable, consuming little energy, made with low-cost wear elements so that it is economical to purchase and maintenance and which is also easily removable so that it can be easily repaired.

 The invention is embodied by an iron, the heating element of which is constituted by a block of cast iron containing a conductive wire wound in a spiral embedded in a refractory material, said block being removably secured on a plate secured to a handle inside which the two ends of the conductive wire are removably connected to the electrical supply cord.

 The heating element is a circular electric plate usually mounted in electric ranges, the manufacturing cost of which is very low. Its diameter is advantageously 8 mm.

 Such a caramelizing iron is very light (around 6 to 7 g), it requires almost half the power of the armored resistors (around 550 watts) and its inertia is low so that the temperature rises are almost instantaneous. which gives him a good energy return.

 The invention will be better understood using the embodiment which will be described below with reference to the accompanying drawing which shows a view in longitudinal section of a caramelizing iron according to the invention.

 In the drawing we see that the iron consists of a hollow handle 1, preferably made of stainless steel, one end of which is connected to a support plate 2 on which a cast iron heating block 3 is fixed by means of a nut 4.

 The block 3 is provided with a heating wire 5 wound in a spiral and embedded in a refractory material.

 The two free strands of the wire 5 extend parallel to the inside of the handle 1 through a hole in the support plate 2. Preferably, inside the handle the two strands of the wire 5 are sheathed in an insulator at high temperature.

 The ends of the strands of the wire 5 are provided with quick connectors cooperating with matching parts on the end of the wires of the power cord 6.

 An insulating handle 7 is fixed to the handle 1 by a screw 8. It houses the connections between the wires of the power cord 6 and the strands of the heating wire 5. The ground wire Q of the power cord 6 is fixed on a tongue secured to the hollow handle 1 and on which the locking screw 8 of the handle 1 is fixed.
