Modular apparatus for processing air, particularly for classified environments and food article making processes in general

1. A modular apparatus for processing air for use in classified environments and processes for preparing meat, dairy and child food and for a pharmaceutical, hospital, chemical, microelectronic, civil and nuclear field applications, said apparatus comprising a recovery air and outside air suction section, said suction section optionally comprising a free cooling fan, an air mixing section, a filtering section, a cold and hot battery section, a spacing section between the batteries of said cold and hot battery section, an air delivery ventilating section, an optional absolute filtering section, an air delivery section, a suction fan section, an ejecting section, an outside air suction section, a chemical dehumidification section including a wheel member, a heat recovery section, an active carbon filtering section, and a humidification section, wherein said apparatus comprises moreover an inner stainless steel shell, constituted by a plurality of modular sections continuously welded to one another, each modular section constituting a section of the apparatus, each said modular section being made of welded smooth stainless steel sheet metal elements coupled to one another by a continuous weldement, said recovery air and outside air suction section comprising an environment recovery air louvered arrangement and an outside air louvered arrangement, wherein said filtering section comprises a stainless steel filter framework supporting a plurality of filtering assemblies, wherein said cold and hot batteries are separated by separating walls and include a first connection for said hot battery and a second connection for said cold battery, wherein said air delivery ventilating section comprises a motor driven fan arranged on a supporting assembly, and an outlet mouth, and wherein said apparatus also comprises access doors allowing to access said modular sections to sterilize said modular sections at a sterilizing temperature greater than 80° C.

2. An apparatus, according to claim 1 , wherein each said section comprises a doubly-slanted bottom, including a slanting portion having a slope larger than 2%, to assure a full removal both of the apparatus washing liquids and of condensate material forming in said apparatus during its normal operation, each said section comprising an independent drain to favor water outflow and prevent stagnating regions from forming.

3. An apparatus, according to claim 1 , wherein said apparatus comprises moreover a sprayed-on high density polyurethane insulating coating arranged between a sheet metal outer covering and an inner stainless steel sheet metal.

4. An apparatus, according to claim 1 , wherein said apparatus comprises moreover a plurality of adjustable foot assembly for installing said apparatus on an installing floor and a plurality of eyebolt assemblies for hanging said apparatus both to civil structures and to metal framework structures.
