CDS Concrete arrowUnique design - The technology adopted in the CDS Dryers for ceramics is continuously developed and improved and incorporates unique features including humidification, dehumidification and inverter controlled air flows to allow between 0% to 100% air circulation.

 

 
Humidification

The Humidification system is designed to hold back the rate of evaporation from the Insulators by creating a high humidity environment within the dryer for the first part of the cycle. Once the insulators have been heated at gradually increasing temperatures to a 'safe' condition, then the humidification system is switched off and product moisture is then allowed to evaporate quickly into the circulatory air streams. This method of humidity control not only offers a 'safe' drying environment for the products, it results in a fast and thermally efficient drying cycle. Dryers that are designed without this type of humidification system result in high product losses, long drying cycles and poor thermal efficiencies.

   
 
Air Circulation

High pressure fans mounted on the roof recirculate air from the dryer and discharge the re-heated air vertically downwards into air distribution cones for horizontal discharge through the product setting. This creates a highly turbulent and variable atmosphere in the dryer meaning that all product surfaces are exposed to an intermittent flow of drying air stream. The air circulation system produces an effective rate of 600 air changes per hour. Air volumes are carefully controlled throughout the drying cycle by means of dampers or speed inverters.

 
Automatic Control

Fully automatic Switchgear and Control Panels may be located either at the dryers or remotely in a air conditioned office or room. The PLC may be panel mounted or desk top and with touchscreen capability. The SCADA software incorporates Main screen; Overview screen and individual System and Engineering screens displaying temperature and humidity set-points, process values, power outputs, cycle start & stop and alarm conditions available. Recipe Programme screen provides the facility to download programs to the PLC for all drying cycle variables. Additional screens provide data logging and trending graphs. The PC may then be remotely accessed via ‘remote desktop’ using an authorised VPN link, to provide online support to the entire system.

Drying Cycles

CDS have built up a vast knowledge of the behaviour of cast sanitaryware pieces in fast drying situations and as all applications are different, every CDS dryer is specifically designed using that knowledge. The CDS dryer will accept a full mix of different products or batch loads of similar style items with the appropriate drying cycle being applied to that mix of products. In certain circumstances the total drying cycle can be as fast as 6 hours or when applied to more luxury styles or US style one-piece up to 18 hours in duration.

The Dryer can accept ware shortly after de-moulding and will be dried down uniformally to below 0.5% moisture content in the times quoted above.

At the end of the cycle it is normal to incorporate a 'cooling period' to reduce the temperature of the ware back to a 'handleable' condition.

De-Humidification Dryers Insulators being manually loaded

Over the past twenty five years, CDS have designed and built many dryers for the ceramic Insulator industry. The drying characteristics of the different clay bodies vary considerably and this, shape complexity are given careful consideration when the system is designed. In many cases we carry out drying trials to fully assess and predict the behaviour of the product in the fast drying process.

Chamber Dryers for Refractories, Advanced & 'Special' Ceramics

For many years, the CDS R-O2™ drying technology has been adopted by approaching 100 customers’ world wide in a variety of industries, including applications in refractories, whiteware ceramics, advanced & technical ceramics, fibre based shapes and various organic and inorganic materials that can tolerate a drying medium in excess of 100°C.

Unlike ‘conventional’ dryers that use heated air as the drying medium, the R-O2™ drying process developed by CDS, uses dry superheated steam at atmospheric pressure.

 
Major benefits
CDS Concrete arrowReduced drying times in all cases of between 30% and 90%. The higher heat capacity of steam, as compared to air, reduces the mass flow rate of steam required to dry the product and that its higher heat transfer coefficient, compared to air, means faster during times.
CDS Concrete arrowHigher throughput, smaller plant, significant capital and operating cost savings
CDS Concrete arrowImproved product quality including sterilisation, conditioning, oxidation prevention
CDS Concrete arrowEnergy consumption up to 50% lower
CDS Concrete arrowDemineralised water, virtual elimination of noxious emissions, reduced anti-pollution costs
CDS Concrete arrowThe system operates in an essentially air free environment. The near absence of oxygen will help mitigate the risk of fire and explosion hazards
CDS Concrete arrowThe technology uses significantly less energy than conventional indirect drying due to the fact that flow-through air is not required, which wastes a lot of heat energy
CDS Concrete arrowWaste Heat from the kilns can further reduce energy costs
CDS Concrete arrowReduced floor space - faster cycles means fewer dryers
CDS Concrete arrowAdaptable for all size, shape and style of product.
CDS Concrete arrowTotally flexible - any production rate and any product mix
CDS Concrete arrowTotally adaptable - all types of cars, conveyors for transportation
