- the screw has an electrical resistance which varies along the axis of rota ⁇ .
- the resistance can be adapted so that the temperature of the screw at the outlet of the enclosure is greater than at the entrance of the enclosure when no product is conveyed so that the temperature difference between the product and the screw remains substantially constant throughout the product stay in the chamber when the product is conveyed by the screw. This increases the efficiency of heat transfer and thus promotes the heat treatment of certain products such as biomass.
- the resis tance ⁇ of the screw may be adapted so that the temperature of the screw speaker entry is greater than Release chamber when no product is conveyed so that the temperature of the screw remains substantially above the melting temperature of the product when the product is conveyed by the screw.
- the screw may therefore have a lower temperature than the fused solids so that they do not melt immediately. It is thus necessary to wait for the divided solids to be conveyed over a certain length before starting to melt. Thanks to this second embodiment, it is possible to ensure that the temperature of the screw speaker entry is Suselling ⁇ higher than the melting temperature of the plastic material when the latter is introduced into the chamber.
- the soli ⁇ divided thus melt and much faster, which promotes their heat treatment.
- the treatment device according to the invention can therefore be adapted to the treatment of a larger number of products than the devices of the prior art.

- the chamber 1 further comprises here a unitary inner envelope of refractory material.
- a technical box 3 is fixed at each end of the chamber 1.
- the chamber 1 here comprises an inlet 4 arranged in the cover of the enclosure 1 substantially at a first end of the enclosure 1.
- the device comprises an inlet chimney 5 which is connected tightly to the input 4 of the enclosure.
- the inlet chimney 5 is for example connected to a device for grinding, compaction or granulation of the product in divided solids or to a pre-conditioning device of the product in the form of divided solids.
- a pre-packaging device is used to heat and dry said product to prescribed values of temperature and relative humidity or to densify the product.
- the divided solids are two-dimensional granules in the form of sheets or core granules in three dimensions.
- the enclosure 1 further comprises an output 6 amé ⁇ swollen here in the bottom of the enclosure 1 substantially at the second of the two ends of the enclosure 1.
- the disposi ⁇ tif has a outlet chimney 7 which is sealingly connected to the outlet 6 of the enclosure 1.
- the outlet chimney 7 is for example connected to a device for cooling the product.
- the bottom and the cover of the enclosure 1 are defined relative to the ground on which the enclosure 1 rests.
- the device comprises means for conveying the product between an inlet of the enclosure and an outlet of the enclosure.
- Said means thus comprise a screw 10 which extends here in the chamber 1 along a geometric axis ⁇ X between the two technical boxes 3 and which is mounted to rotate around said geometric axis X in the chamber 1.
- the screw 10 is for example stainless steel.
- the screw 10 here has a helical coil shape which is fixed, for example by welding, at its two ends at the end of a shaft section 11. Each of said shaft section 11 is connected at its other end by the through a flange 12, to a coaxial shaft 13 which passes through the associated end technical box.
- the conveying means furthermore comprise means for driving the screw 10 around the geometric axis X which are here arranged in one of the technical boxes 3.
- the means of driving in rotation com ⁇ carry an electric motor 14 and the mechanical connection means between the motor output shaft and a Extremists ⁇ moth coaxial shaft 13 associated, the coaxial shaft 13 itself driving the screw 10
- the training means in rotation here comprise means for controlling the speed of rotation of the output shaft of the motor which comprise for example a speed variator.
- the control means thus make it possible to adapt the speed of rotation of the screw 10 to the conveyed product, that is to say to adapt the residence time of the product in the enclosure 1.
- the device further comprises means for heating by the Joule effect of the screw 10 which are here arranged in the technical boxes 3.
- the heating means comprise means for generating an electric current and means for connecting the two ends of the screw to the two polarities of said generating means.
- each coaxial shaft 13 is rigidly integral with a coaxial drum 20 of electrically conductive material, on which rubbing brushes 21 for supplying the electric current, connected by conductive wires (not shown here) to the means for generating electricity. an electric current.
- the screw 10 is thus traversed by the same intensity all along the geometric axis X.
- the heating means com ⁇ carry means for regulating the intensity of the electric current flowing through the screw 10.
- the control means here comprise a dimmer interposed between the means for generating the electric current and the connection means. The regulating means thus make it possible to adapt the electrical intensity passing through the screw 10 to the product conveyed.
- the product to be treated is introduced into the inlet stack 5 in the form of divided raw solids or pre-conditioned divided solids and the screw 10 continuously drives the divided solids towards the outlet 6 of the enclosure 1. Because of the temperature of the screw 10, the divided solids gradually soften until melted. The screw 10 thus ensures both a thermal treatment of the product and the conveying of the pro ⁇ duct.
- the screw 10 here comprises so-called flat turns, each turn having a rectangular section of area S (illustrated in FIG. 4).
- Section S is defined by the product of the thickness e of the turn (thickness defined along the geometric axis X) by the height h of the turn (hau ⁇ tor defined in a direction perpendicular to the geometric axis X).
- the screw 10 is divided along the geometric axis X into five successive portions 28a, 28b, 28c, 28d and 28d which pre ⁇ feel distinct electrical resistances.
- the first portion 28a extends along the geometric axis X between the first end of the screw 10a, which is located sen ⁇ sibly at the inlet chimney 5, to the beginning of the second portion 28b.
- the second portion 28b extends along the axis X between the end of the pre ⁇ Mière portion 28a and the beginning of the third portion 28c.
- the fifth and last portion 28e extends along the geometric axis X between the end of the fourth portion 28d and the second end of the screw 10b which is located substantially at the outlet chimney 7.
- the five portions are of course in solidarity with each other.
- each portion of the screw has a height of turns different from those of the other portions, the turns being all identical to each other within the same portion.
- each portion of the screw has a resistance different electrical power than other portions.
- the resistance of a turn is defined by:
- the section of the turn is modified so that the resistance of the turn is changed.
- the resistance of the portion is proportional to that of its turns, the resistance of the portion is thus modified.
- the first portion 28a has a first turn height hi
- the second portion 28b has a second turn height h 2 less than the first turn height hi
- the third portion 28c has a third turn height h 3 lower than the second hau ⁇ turn torque h 2
- the fourth portion 28d has a fourth turn height h 4 lower than the third hau ⁇ tor turn h 3
- the fifth portion 28 e has a cin ⁇ quidiagème coil height h of 5 less than the fourth height coil 4 h.
- the resistance of the screw 10 thus increases along the geometric axis X between the inlet 4 of the enclosure and the outlet 6 of the enclosure.
- the temperature of the screw 10 at the first portion 28a is less than that at the second portion 28b which is itself less important than that at the level of the third portion 28c, which is itself less important than that at the level of the fourth portion 28d which is itself less important than that at the level of the fifth portion 28th.
- FIG. 5 thus illustrates the temperature profile of the screw 10 after the screw 10 has been heated to reach a steady state and without any product being conveyed by the screw 10 (profile represented by the dashed curve) .
- the resistance profile of the screw 10 is represented by the solid line curve.
- FIG. 5 also illustrates a temperature profile of a constant strength prior art screw along the axis of rotation of the screw after the screw has been heated to a steady state and without no product is conveyed by the screw (profile represented by the curve in solid lines and squares).
- the screw of the temperature profile 10 clearly illustrates that the temperature is greater at or ⁇ calf junction 6 of the enclosure 1 that the temperature at the chamber entry level 1.
- Such temperature profile is particularly suitable for heat treatment of biomass.
- the device is identical to the device according to the first embodiment of the invention with the difference that the resistance of the screw decreases along the geometric axis X between the input of the speaker and the speaker output.
- FIG. 6 thus illustrates the temperature profile of the screw according to the second embodiment of the invention after the screw has been heated until reaching a steady state and without any product being conveyed by the screw (profile represented by the dashed line).
- the resistance profile of the screw is represented by the solid line curve.
- FIG. 6 also illustrates a temperature profile of a constant strength prior art screw along the rotational axis of the screw after the screw has been heated up to to reach an established speed and without any product being conveyed by the screw (profile represented by the curve in solid lines and squares).
- the temperature profile of the screw according to the invention clearly illustrates that the temperature at the speaker output is much less than that at the input of the enclosure.
- Such a temperature profile is particularly suitable for the heat treatment of a plastic material.
- the resistance of the screw according to the second embodiment is adapted so that when the screw conveys a product the temperature of the screw remains substantially constant and above the melting temperature of the product and this over the entire lon ⁇ LATIONS the screw.
- the product here is a plasticized material ⁇ .
- FIG. 7 thus illustrates the temperature profile of the screw thus adapted after steady state and without the plastic material being conveyed by the screw (profile represented by the solid line curve supplemented by squares) and the temperature profile of the same screw when it conveys the plastic (profile represented by the dashed curve completed with squares). It is also illustrated the temperature profile of a screw of the prior art after steady state and without the same plastic material being conveyed by the screw of the prior art (profile represented by the solid line curve supplemented by triangles ) and the temperature profile of the same screw of the prior art when it conveys the plastic material (profile represented by the dashed curve supplemented with triangles).
- the screw of the invention remains at a temperature greater than that of the melting temperature of the plastic material over the entire length of the screw.
- the temperature of the screw at the enclosure inlet remains greater than the melting temperature of the plastic material when it is introduced into the enclosure.
- the plastic material thus melts much faster thanks to the screw of the invention with the screw of the prior art which promotes its heat treatment.
- the device according to the invention is adaptable to heat treatment of a wide range of products mainly through the definition of the screw 10.
- each turn of the screw may comprise a portion different so that the resistance of the screw gradually increases from one end of the screw to the other.
- the screw may comprise at least a portion of resistance less important (or more important) than the two portions framing.
- the resistance of the screw is modified along the geometric axis X by varying the height of turns of each portion, it will be possible to play on other parameters.
- the screw may comprise turns which have distinct sections from one portion to another, distinct thicknesses, thicknesses and distinct heights, distinct lengths.
- the portions may be of different lengths.
- the portions may be of different materials.
- the portions may have a different pitch of turns.
- the masses of the portions may be different.
- the definition of the screw may also be related to other parameters other than the electrical resistance of the screw.
- the definition of the screw may take into account the fact that the volume of the product to be treated does not vary or little in the enclosure (for a simple pasteurization of a product for example) or that the volume of the product to be treated varies in the enclosure (for pyrolysis of products such as biomass there may be a formation of gas that changes the volume of the biomass).
- the interstitial volume between the turns is preferably kept constant along the geometric axis X.
- the fill rate of the screw decreases between the input of the speaker and the output of the enclosure.
- the interstitial volume of the screw is then decreased between the inlet of the chamber and the outlet of the enclosure to maintain the same filling rate along the geometric axis X of the screw.
- the definition of the screw may also take into consideration the value of the exchange surface between the product and the screw. Preferably, it is sought to ten ⁇ ter to maximize said exchange surface having the pitch P of the screw as low as possible, the height h of the turn as large as possible and the filling rate ⁇ sage of the screw the more importantly possible.
