Definitions

the invention relates to a multi-stage cooling-drying unit for pasty products shaped into tubes.
the extrusion in the shape of a sausage of a pasty product requires bringing this product to a minimum temperature 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 must be cooled and dehumidified enough to be able to be worked before any subsequent treatment, cutting, packaging, etc.
the tubes include an in-line cooling tunnel through which the tube passes, this tunnel comprising various cooling means, for example, air or gas flow, spraying of a cryogenic fluid, etc.
said cooling means used are difficult to control at the inlet and outlet temperatures, in particular when combining several cooling processes as in the cited patent.
the invention aims to cool and dry the product simultaneously and to remedy the aforementioned drawbacks.
the cooling unit can be supplied with product by conventional conveyor belts without significant modifications or adaptations.
a temperature sensor and a heating element are disposed on the air ring circulation path at the outlet of the cooling compartment to allow permanent and continuous temperature adjustment and control as well as one or more phases of Punctual or successive super-cooling.
the general inventive idea consists in providing the routing path in a circulation unit of an extruded product as a succession of stages of so-called circulation conveyor belts and a cooling-drying by associated circulation of a cooling air flow. with regulated temperature and controlled hygrometric content in a closed isothermal enclosure.
the air flow circulates in a ring between two separate juxtaposed compartments containing for one the refrigeration batteries producing the flow of cooling air and for the other the product in the path along an elongated path by the successive passage of '' one floor on the lower floor from the top to the bottom of the unit to exit at its lower part located diagonally from the entrance.
the unit according to the invention defines an enclosure 1 enclosed in an isothermal enveloping bodywork which defines a transportable container.
the interior volume of the enclosure is divided by a longitudinal partition wall 3 into a conveying compartment 4 of the extruded tube or circulation compartment and a refrigerating compartment 5 ensuring the continuous production of an aeraulic 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 delimit on each side an inlet 6 or outlet 7 passage for the cooling air flow.
the unit has an upper inlet 8 located on the upstream side towards which a feed conveyor belt 9 ends.
the outlet 10 takes place at the opposite end at the bottom by a conveyor belt take-up ramp 11 which ensures the evacuation downstream to the conformation stations.
the conveying compartment 4 of the dough develops in length and has a width slightly greater than that of the supply and evacuation conveyor belts. It includes a vertical succession from top to bottom of conveyor belts for circulation such as horizontal and longitudinal 12,13 for the transit of the product from top to bottom. These bands are driven in coordinated and alternating movement in advance so as to convey the roll of dough from the inlet to the outlet along an elongated path formed by a plurality of stages of alternating drive progression.
each circulation conveyor belt protrudes from the upstream side with respect to the belt located just above, so as to allow the direction of the rod to be changed by turning in the opposite direction.
This reversal is guided by passive or active deflectors located alternately at the end of the strip at the downstream end, thus ensuring the continuous path of the tube in the circulation compartment by longitudinal displacements alternately forwards and backwards.
the first conveyor belt in the upper position 14 and the last conveyor belt in the lower position 15 make the junction respectively with the supply conveyor belt 9 and the return conveyor belt 11.
the total number of circulation conveyor belts is variable because it depends the heat exchange capacity and the length of the strips. It must of course be odd to respect the input-output diagonal.
a flow of cold air is sent from the refrigerating compartment 5 through the inlet passage 6 and passes through the circulation volume to exit on the opposite face through the outlet passage 7 bent. This defines a cooling-drying ring successively passing through one and then the other compartment in one direction.
the air circulation in the circulation compartment takes place along it over its entire height from the downstream side to the upstream side like a flow against the current with respect 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 said evaporators.
the evaporator batteries have their own fan, respectively 19.20 which precipitates an air flow on the cold exchange surface. These are for example four batteries arranged in a 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 the enclosure so as to facilitate the supply of energy and maintenance and to constitute a complete transportable unit.
the belt drive motor 22 for conveying the dough is placed at the downstream end, and actuates a driving roller such as 23.24 for supporting each circulation band such as 12.13 by means of suitable reduction gears.
the refrigerating compartment has in its end volume a heating element 25 and a temperature probe 26 located close to one another.
the temperature sensor 26 is arranged in the cooling air circuit at the inlet passage 6 communicating with the circulation compartment downstream of the heating element 25, so as to provide a useful indication of the temperature of the drying coolant for controlling the operation of the refrigeration unit from the outlet temperature of the cooling air flow.
the heating element occupies the entire exit passage section of the refrigerating compartment.
the air leaving the refrigeration compartment is heated to move the operating point on the Mollier diagram and move it further away from the dew point, by artificially influencing the temperature sensor which controls the regulation of the operation of the refrigeration installation. This action forces additional production of more or less long duration in the refrigeration compartment.
