A drying device of at least one optical glass, comprising: - an enclosure, intended for accommodating at least one optical glass having at least one air inlet and at least one air outlet, said at least one air inlet (19, 21) having a diffuser (23, 25) arranged to generate an air stream, - an air circulation circuit arranged to blow a drying air flow from said at least one inlet to said at least one outlet, - a discharge orifice, in fluid communication with the enclosure, so as to discharge a first part of the drying air flow, called the discharged air flow, out of the drying device - a collector having: ∘ an inflow of a second part of the drying air flow, called return air in fluid communication with the enclosure from said at least one air outlet, o an inflow of an external air flow to the drying device, o an outlet in fluid communication with the circulation circuit - a support of the at least one optical glass, the support being disposed inside the enclosure characterized in that said support is arranged so that the emerging and incident surfaces of the at least one optical glass each have an area of contact with the air contained in the enclosure when the at least one optical glass cooperates with the support, the relative disposition of said support and said diffuser (23,25) being such that said air stream is homogeneous and tangential to the emerging and incident surfaces of said at least one optical glass when the at least one optical glass cooperates with the support. - an enclosure, intended for accommodating at least one optical glass having at least one air inlet and at least one air outlet, said at least one air inlet (19, 21) having a diffuser (23, 25) arranged to generate an air stream, - an air circulation circuit arranged to blow a drying air flow from said at least one inlet to said at least one outlet, - a discharge orifice, in fluid communication with the enclosure, so as to discharge a first part of the drying air flow, called the discharged air flow, out of the drying device - a collector having: ∘ an inflow of a second part of the drying air flow, called return air in fluid communication with the enclosure from said at least one air outlet, o an inflow of an external air flow to the drying device, o an outlet in fluid communication with the circulation circuit ∘ an inflow of a second part of the drying air flow, called return air in fluid communication with the enclosure from said at least one air outlet, o an inflow of an external air flow to the drying device, o an outlet in fluid communication with the circulation circuit - a support of the at least one optical glass, the support being disposed inside the enclosure characterized in that said support is arranged so that the emerging and incident surfaces of the at least one optical glass each have an area of contact with the air contained in the enclosure when the at least one optical glass cooperates with the support, the relative disposition of said support and said diffuser (23,25) being such that said air stream is homogeneous and tangential to the emerging and incident surfaces of said at least one optical glass when the at least one optical glass cooperates with the support.
