Hot Air Drying Oven.
Thanks to a long experience within the pharmaceutical, nutraceutical, cosmetic, and food industries, Steelco offers a wide range of hot air static dryers to meet the most challenging market requirements.
The EG Series is designed for optimizing process parameters for effective, uniform, and gentle drying by hot air of materials such as granulates, pellets, powders, porous load, and equipment used in pharmaceutical industry processes. In addition, upon request and for particular types of applications – products containing a high percentage of alcohol, solvents, or materials classified as inflammable and potentially explosive – the electrical system and components of the machine can be supplied to be compliant with the flameproof type (ATEX Directives).
Available in single or double door pass-through hinged door versions, the devices feature chamber volumes from 330 to 10.000 liters (11.7 to 353 cu ft). On request and previous Steelco approval shall be possible to require customized chamber dimensions.
The EG Series of hot drying ovens are high-performing, reliable, and easy to use. Its cycle has been specifically designed to minimize time and energy consumption while maximizing efficiency and throughput-drying process temperature ranges from 50 to 160°C. In addition, upon request, the unit can be supplied with a self-washing system for performing CIP (Clean-In-Place) of the chamber and air ducts.
The EG Series is designed, manufactured, validated, and documented according to the latest global practices and standards to facilitate customers’ compliance with current Good Manufacturing Practices (cGMPs).
Drying Quality Process
The unit has electrical heating elements and air recycling fan(s) positioned on top of the chamber. Pre-filters and HEPA filters are installed on the inlet and exhaust air ducts to prevent cross-contamination. Monitoring of chamber pressure and HEPA filters efficiency by differential pressure transmitters. Absolute filters’ housing provided with accessories necessary for the DOP test. The air cooling is carried out by a heat exchanger running by chilled or softened water.
Even Temperature Distribution
Differentially perforated walls, airspeed, and temperature control ensure an extremely air drying quality process. Tri-clamp connections for air quality monitoring and validation activities installed on fascia. As standard, one temperature product probe in chamber is provided for temperature monitoring. Upon request, additional temperature probes are provided.
Reliable and Hygienic Construction
Chamber, machine body, and aeraulic system made of AISI 304 stainless steel as standard, AISI 316 stainless steel available upon request. Polish finish chamber with rectangular cross-section and rounded internal angles. Chamber bottom fitted with guides for moving the product holding carts. Fast-closing swing-out doors are equipped with an interlock system by a pneumatic device that prevents the door from being opened during the cycle.
Integrated Automation Architectures
Steelco can install new equipment into an existing automation system by adopting a simple (HMI) or more sophisticated (SCADA) man-machine interface. User-friendly control systems developed according to the latest ISPE GAMP© Guidelines and designed for FDA 21 CFR Part 11, EU Annex 11 compliance. System platforms available include Siemens or Rockwell/Allen-Bradley, which are completely integrated with the client’s IS system, and comprehensive network services such as integration with MES can be provided. In compliance with the individual internal policies of each customer, Steelco Group offers remote service access by using virtual private networks to ensure the confidentiality and safety of all transferred data.
Quality Engineering Process and Qualification Services
Our equipment’s technical consulting, design, engineering, project management, and commissioning and qualification services are offered, with customers appreciating the cost-effective, high-performance solutions provided to resolve complex washing and sterilization challenges. Design qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) are provided in the standard version or customized according to the final scope of supply. Customers are always welcome to visit Steelco factories to see design and manufacturing methods and audit our processes. Steelco Group is available anytime to support customers during all acceptance on-site, including process development and mapping.
The chamber and door(s) are externally insulated with high-density ceramic heat insulation and covered by AISI 304 stainless steel panels.
Hermetically sealed doors with a special-profile FDA certified silicone inflatable gasket.
External/Internal loading cart in AISI 304 or optionally in 316L stainless-steel, equipped with guides for shelves positioning.
Air Cooling System
The air cooling system inside the chamber is carried out by heat exchanger running by chilled or softened water. Water return system for recovery softner water loop available as option.
The on-board VPN router communicates on the local network with the PLC and the HMI, and allows remote connection from a computer, tablet, or smartphone without going on-site, drastically reducing support costs and improving machine uptime.
The machine is developed considering technicians’ access to the maintenance and service area – easy access to all components conforming to safety regulations.
Remote FAT service
In order to support the equipment verification procedures for our clients, we then introduce an alternative way to perform FAT – Factory Acceptance Testing, usually realized onsite. Remote FAT is a smart cloud-based service to support customers step by step in all procedures and testing and the production of related documentation that can be executed remotely, reducing the time required for staff to be away from the office and the associated costs including travel, accommodation, visa application, etc.
