Drying different sized pieces in a vertical oven without compromising production efficiency

Everyone knows how efficient drying is inside a FIFO oven such as OMNIDRY, our vertical oven. The issue some companies regularly face occurs when a minority of pieces are significantly larger than the majority of pieces transiting the oven. What normally happens? These oversize pieces will be removed manually from the production circuit and will undergo the drying process elsewhere, in another oven, taking longer. Clearly, this issue concerns companies whose finishing capabilities allow them to handle much larger pieces.

A patented solution overcomes the need for two drying options

FLEXPRO is a patented system built into the version of OMNIDRY featuring 3 chambers. Without penalising productivity in any way, this system enables much larger pieces to enter the same oven and be dried without interrupting the process. Space is created exactly when and where it is required to accommodate the piece without reducing the oven’s overall capacity. This allows companies to exploit the high-speed drying process ensured by a typical FIFO oven and avoids the need to find another solution and twice as much floorspace.

One of its kind, with no compromise

Other ovens either favour productivity and exclude any form of flexibility, or vice versa. OMNIDRY with FLEXPRO accepts no compromise, just efficient production together with full flexibility. For companies handling more or less 10% larger pieces in their daily production, FLEXPRO saves money, saves space and saves them from stopping each time a large piece reaches the drying stage.

Industry 4.0 is the biggest revolution since the industrial revolution and is happening at such a speed that today’s businesses and factories that fully grasp the importance of efficiency, supervision and personalized service will be the ones who exploit the technological opportunities offered by our new suite of digital tools.

The exterior of a building can be embellished with any number of techniques. Sidings represent a simple solution, easily applied and a way of protecting the structure itself. The sidings might just be rectangular slats, but the more creative you get, the more you need to set up a finishing process with the appropriate equipment. We at Cefla Finishing have responded to many requests and the knowledge and experience gathered around the world enables us to tailor each integrated line we design to best suit a customer’s needs. This is one of many line set-ups using spray coating equipment and a vertical oven for additional flexibility.

After initial surface coating at a rate of 90-100 g/sqm in a spray coater such as Easy, a pigmented, bi-component, water-based topcoat can be applied before drying in a vertical oven Omnidry for 45  min. at 60°C. Where required, the grout lines, which add a special visual effect to a decorative siding, can be coated in a darker tone using an anthropomorphic painting robot iGiottoApp. This coat of single-component, water-based varnish can be applied at a rate of 35-40 g/sqm prior to a seven-minute drying stage in Aquadry.

This is just one way of approaching the task of decorating sidings. Let us know what your specific needs are and our process engineers will research a tailored solution to bring you added efficiency, ensure improved surface enhancement quality and keep a close eye on your paint consumption.

Cefla’s Vacuum Finishing Systems are intended for small- and medium-sized operations.

Available in either a water-based or solvent-based compatible solution, the system has a compact footprint that is ideal for shops with space limitations. The system combines three processes into one system, featuring a denibbing unit, application vacuum coater, and either a drying or curing tunnel based on coating specification. The system allows you to be flexible enough to quickly ramp up to accommodate a large order, or pivot with multiple small orders. Utilizing a 12-inch conveyor, the system moves parts through an application head where a controlled amount of coating is circulated around either three or four sides of each part. The application head has a lever that is manually opened or closed to either increase or decrease the amount of coating that encounters each part. From there, the part is conveyed through a short wave IR drying oven. After exiting the oven, unless there is a desire for the parts to go through another coating process, the parts are ready to pack and ship. The CVR Vacuum Finishing System has an optional denibbing unit; denibbing roughens or smoothens a part to the desired grain.

Additionally, the system is environmentally friendly. There are no VOC's produced from the drying process, meaning your carbon footprint will remain low and there are no permitting or government compliance regulations to monitor. The CVR Vacuum Finishing System has a working width of 8- to 12-inches and optimal working length of 24 inches, making it ideal for optimizing the production of linear profiles and flat boards including shiplap. The popularity of shiplap in the North American market is no secret; it has become quite the star in North America with its feature on several hit reality and DIY (do-it-yourself) television series. Vacuum technology allows shops of any size to automate their finishing process and take advantage of this trendy material.

Other system features include:

• No VOC’s, no emissions, no permitting
• Small footprint
• One system comprised of multiple processes – no need for different sets of equipment
• Options for water-based and solvent-based coatings
• Machine-side control panel is easy to use with a touch screen featuring large print and color graphics

Not using water-based coatings? The CVS vacuum coating system has the same footprint as the CVR system, but is compatible with solvent-based coatings and has a standard denibbing unit located before the application head.

These machines are built exclusively to support the North American market by Delle Dedove technologies, also known as DV Systems. Contact us today.

OMNIDRY, the final frontier in vertical oven design, provides the revolutionary capability for fully automatic management of piece height while retaining all the outstanding characteristics of a standard Cefla vertical oven.

It can carry out all three stages (flash off, drying and cooling), even for coatings that need longer drying times, while minimizing the use of floor space.

• A variable number of trays, from 16 to 168, available with belt or rack configuration
• Horizontal upgrade: reduction of the conveyor length
• Extreme modularity: Omnidry can be expanded with an additional 2 or 4 sections.
• Flexible system layout
   

FLEXIBILITY AND PRODUCTIVITY

FLEXPRO (patented), is the revolutionary feature of the new Omnidry, which allows managing the loading thickness completely automatically. It represents the perfect compromise between productivity and flexibility.
Thanks to FLEXPRO, the system recognizes inbound objects, independently adjusting the load height. It's able to handle the entire cycle without the intervention of the operators and never stop the production. This innovative solution is perfect for robotic applications that allow the finishing of pieces with different sizes. Cefla’s expertise enables us to take another major step forward: the new generation of Omnidry vertical ovens provides automatic management of variation in the piece.
