Revair Reverse-Air Metal Dryer Machine Cold and Air Freeze Dryer

Reverse-air drying uses periodically reversed airflow through the product bed or drum to fluidize and redistribute the load, promoting uniform heat and mass transfer. This reduces drying times, minimizes hot spots and improves overall drying consistency for a wide range of materials.

The product name includes both 'Cold and Air Freeze Dryer' and 'Reverse-Air', suggesting it is designed for cold-air drying with reverse-air technology. True laboratory/industrial freeze-drying (lyophilization) normally requires vacuum pumps and condensers; those components are not listed in the supplied specifications, so confirm freeze-drying capability and required accessories with the supplier if you specifically need vacuum-based lyophilization.

Typical applications listed include food products, textiles, chemicals, pharmaceuticals, agricultural products and laboratory samples. Always verify material compatibility (thermal sensitivity, particle size, dust/explosion risk) with the manufacturer before processing.

The machine is configured for 220V AC power and uses air cooling. Ensure you have the appropriate AC supply and adequate ventilation/airflow at the installation site.

The specification field shows 'Oxygen' for gas type, but dryers commonly operate with air. This may be a product-sheet entry or indicate optional process gas compatibility. Do not assume oxygen is required; contact the seller/manufacturer to clarify gas requirements and to discuss inerting options (e.g., nitrogen) if your materials are oxygen-sensitive or flammable.

The specification lists 'Mute: No', indicating it is not designed to be silent. Exact noise levels (dB) are not provided; request measured sound pressure levels from the manufacturer if workplace noise limits or hearing protection requirements are a concern.

Key components are lubricated (screw, bearings and moving parts). Routine maintenance generally includes scheduled lubrication, inspection of the motor and pressure vessel, filter replacement or cleaning, checking seals and fasteners, and following the manufacturer's service intervals. Obtain the operator and maintenance manual for detailed procedures.

Yes — the listing indicates 'Video Outgoing Inspection' and a 'Machinery Test Report' are provided with the unit.

Package size is listed as 130 x 50 x 50 cm and gross weight is 68.000 kg. The machine is described as stationary, so allow space for installation, ventilation, access for maintenance and safe handling of the boxed unit.

The machine is intended for drying those product types, but regulatory and hygiene requirements vary. For food or pharmaceutical use you may need specific surface finishes, cleanability documentation, GMP compliance or validation support. Confirm certifications and sanitary design options with the supplier before purchasing.

Customization options are common for industrial dryers, but specific capacities and configurations are not provided in the basic spec. Contact the manufacturer or vendor to discuss throughput requirements, tray/shelf options, control systems and custom engineering.

The specification does not list training explicitly. Many suppliers offer operator training and commissioning as part of sale or as an add-on. Ask the supplier about available training, manuals and safety documentation.

Typical safety features include emergency stop, motor overload protection, temperature and pressure monitoring, guard interlocks and electrical protection. Because the spec lists oxygen and lubricated components, discuss explosion risk mitigation (if drying powders), ventilation, and any required inerting or gas-monitoring with the vendor and your safety officer.

Cleaning methods depend on the materials processed. General guidance: disconnect power, follow the manufacturer's cleaning procedures, use compatible cleaning agents that do not corrode surfaces or affect lubricated parts, rinse and dry thoroughly. For food/pharma use follow validated cleaning-in-place (CIP) or cleaning protocols approved for your quality system.

Warranty, spare parts availability and service contracts are not specified in the provided information. Contact the supplier or manufacturer to confirm warranty terms, lead times for spare parts, availability of technical support and options for preventive maintenance contracts.
