BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Field of the Invention
The invention concerns an improved drier for the continuous drying and conditioning treatment of hides or fabrics.
2. General State of the Art
It is a known fact that the drying and conditioning treatment of hides or fabrics, is carried out by means of driers, essentially consisting of a drying chamber into which the products are inserted and which is provided with a system for heating and dehumidifying.
In particular, a continuous drier for hides being the object of the international registered No. 93/00654 in the name of same inventor is known, wherein the hides are inserted into a drying chamber through a loading unit, said drying chamber presenting a plurality of drying belts, overlying another and receiving in succession the hides coming from the loading unit.
At the end of the run of the drying belts, an unloading belt conveys the dried hides to the exterior.
Said system is provided with a high-frequency unit for monitoring the humidity, and therefore for conditioning the expelled hide, and with a heating and dehumidifying system consisting of a heat pump in the drying chamber.
One inconvenience that said drier presents is that the use of a heat pump for obtaining the heating and the dehumidification of the drying chamber, and therefore of the hides, is very costly.
In fact, since the hides loaded into the drier contain humidity amounting to about 50% in weight, it is clear that it becomes very costly to eliminate such a great quantity of water by using a heat pump for the drying and dehumidifying process, considering that its optimum performance is achieved around 35.degree.-37.degree. C. and, therefore, requires rather long drying times.


SUMMARY OF THE PRESENT INVENTION

The purpose of the present invention is to overcome such an inconvenience by obtaining a drier provided with an improved drying and dehumidifying unit which permits to reduce the drying times of the hides, as compared with the driers belonging to the known technique.
Another purpose is that such a drying and dehumidifying treatment can be obtained at a low cost.
The described purposes are achieved by means of a drier for the continuous drying and conditioning treatment of hides or fabrics which, in accordance with the main claim comprises: product to be treated inside a drying chamber; to receive the material conveyed by the loading unit; treatment has been completed; in that said drying chamber is subdivided into a first area communicating with first means for heating and dehumidifying the air circulating in said first area and into a second area communicating with second means for heating and dehumidifying the air circulating in said second area.
According to one preferred embodiment said first heating and dehumidifying means consist of a heating battery, fed by any kind of hot fluid and thermofrozen by means of an electronic control unit provided with feelers for monitoring the temperature and the humidity.
Said second means for heating and dehumidifying the air consist instead of a heat pump comprising a compressor which keeps a refrigerating fluid in circulation inside a closed circuit connected both with a condensing battery for dehumidifying the air and with a heating battery for heating the air itself.
Advantageously then, the drier according to the invention permits to obtain a better monitoring of the humidity on the finished product.
Moreover, energy saving is advantageously obtained, with drying times being shorter as compared with the times necessary to the driers belonging to the known technique.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter.
