Definitions
- the invention relates to a multi-stage unit cooling-drying for pasty products shaped in strands, as defined in the preamble of claim 1.
- a unit is known, for example, from document US-A-2 923 138.
- the extrusion in the shape of a rod of a product pasty requires bringing this product to a temperature minimal so that it has sufficient fluidity, and to improve other physical properties of the dough.
- the extruded product On leaving the extrusion installation, the extruded product should be cooled and dehumidified enough to be able to be worked above all further processing, cutting, packaging, etc.
- flanges include a tunnel in-line cooling through which the flange passes, this tunnel with various cooling means, by example, air or gas flow, spraying a cryogenic fluid, etc ...
- said means of used cooling are hardly controllable at the inlet and output, especially when combining multiple cooling processes as in the cited patent.
- the object of the invention is to cool and simultaneously dry the product and remedy aforementioned drawbacks.
- the cooling unit can be supplied with product by conveyor belts classics without modifications or adaptations important.
- a temperature sensor and an element are arranged on the circulation path in air ring at the outlet of the compartment cooling to allow adjustment and temperature control permanently and continuous as well as one or more phases of super-cooling punctual or successive.
- the routing path is planned in a circulation unit of an extruded product as a succession of stages of so-called circulation conveyors and a cooling-drying by associated circulation of a temperature cooling air flow regulated and with controlled humidity content in a closed insulated enclosure.
- the air flow circulates in a ring between two separate compartments juxtaposed containing for one the refrigeration batteries producing the cooling air flow and for the other produces it along a path lengthened by the successive passage from one floor to the other bottom from top to bottom of the unit to exit at its lower part located diagonally from the entrance.
- the unit delimits a enclosure 1 enclosed in an enveloping body isotherm which defines a transportable container.
- the interior volume of the enclosure is divided by a wall 3 longitudinal separation in a compartment routing 4 of the extruded tube or compartment circulation and a refrigeration compartment 5 ensuring continuous production of an air flow of cooling and drying suitably regulated in temperature and humidity.
- the length of the partition wall 3 is less than that of the interior volume of the enclosure so as to define an entrance passage on each side 6 or outlet 7 of the cooling air flow.
- the unit has an upper entry 8 located on the upstream side towards which a strip ends feed conveyor 9. Exit 10 takes place opposite at the bottom by a ramp of conveyor belt 11 which ensures evacuation downstream to the conformation stations.
- the dough conveying compartment 4 grows in length and has width slightly higher than that of conveyor belts supply and discharge. It includes a vertical succession from top to bottom of bands circulation conveyors such as 12.13 horizontal and longitudinal for the transit of product from top to bottom. These bands are driven in coordinated and alternating motion in advance so as to route the dough roll from the inlet to the outlet along an elongated path formed by a plurality of stages with alternating direction drive progression.
- each conveyor belt of circulation exceeds the upstream side compared to the strip located just above, so that the change of direction of the flange by a reversal in the opposite direction.
- This reversal is guided by passive or active deflectors located alternately in end of strip at the downstream end, thus ensuring continuous path of the tube in the compartment circulation by longitudinal displacements alternately forward and backward.
- the first traffic lane in position upper 14 and the last strip in position lower 15 make the junction respectively with the feed conveyor belt 9 and the belt recovery conveyor 11.
- the total number of belts circulation conveyors is variable because it depends on the heat exchange capacity and the strip length. It must of course be odd to respect the input-output diagonal.
- a cold air flow is sent from the refrigeration compartment 5 through the inlet passage 6 and crosses the traffic volume to come out on the opposite face by the bent outlet passage 7.
- the air circulation in the circulation compartment runs along it over its entire height from downstream side to the upstream side like a counter-current flow compared to the general direction of progression of the product in the production line.
- the large diameter main fan is placed upstream of the evaporators in the direction of circulation of the cooling flow, in order to ensure good distribution and mobility of the fluid around of said evaporators.
- Evaporator batteries have their own fan, respectively 19.20 which precipitates an air flow on the cold exchange surface. he for example, four batteries arranged in square at the same distance from each other.
- the compressor 21 of the refrigeration unit is placed at the upstream end of the unit inside of the enclosure so as to facilitate the supply of energy and maintenance and to build a unit complete transportable.
- the belt drive motor 22 of the dough is placed at the downstream end, and drives a motorized roller such as 23.24 of support of each traffic lane such as 12.13 per through adapted reduction gears.
- the refrigeration compartment has in its end volume a heating element 25 and a temperature probe 26 located near one of the other.
- the temperature sensor 26 is arranged in the cooling air circuit at the entry passage 6 communicating with the compartment circulation downstream of the heating element 25, so to provide a useful indication of the temperature of the drying coolant to control the operation of the refrigeration unit from the air flow outlet temperature of cooling.
- the heating element occupies the entire passage section from the refrigeration compartment.
- the air leaving the refrigerating compartment is heated to move the operating point on the Mollier diagram and further away from the point dew, by artificially influencing the sensor temperature which controls the regulation of the operation of the refrigeration system. This action allows to force an additional production of more or less long duration of cold in the refrigeration compartment.
