Flat drying furnaces category.

The drying furnaces or or lamination hood allows to obtain performance in processes where the drying systems are positioned on a flat or curved segment line.

The possibility of obtaining a flat geometry is ideal in vertical drying hoods or furnaces where the rollers are positioned outside the hood, and the coated film can be dried or dried quickly on one side. The drying hoods or blowers are suitable for the lamination or coating or drying station for painting or coating lines and are usually applied in single stations or stations with several drying elements or several drying stations in series.

Rimor’s hoods or drying ovens are made with superior quality and cover the nozzle with a teflon or stainless steel or galvanized cover.

The drying or coating or painting line performed with Rimor’s plane hoods or drying ovens allows to obtain an optimal result.

The machine can be arranged as a horizontal or vertical drying hood.

The FLAT version model guarantees minimum hood heights, unusual in the market.

The curved drying hood is normally used on coating machines, rotogravure machines or machines where there is a series of curved rollers where the film is conveyed and transported using rollers placed on a precisely curved line.

The drying system for curved lines is also very useful for obtaining stable drying for delicate printing processes such as rotogravure.

It is also used as an alternative to flat segments. The system can then be obtained with more rays of curvature and more drive rollers, both idle and motorized.

The curved RECUBE DRY drying system is sliding to inspect the nozzles and is silenced and insulated.

The curved drying hood of Rimor S.r.l. it is precise and can be combined with all the technologies present, with lateral suction, between one nozzle and the other, from above or below the film.

The drying hood has an accuracy of + -1 m / s and + -1 ° C, with the possibility of having a version that can be inspected or with a removable nozzle.

The aspiration from above expresses an evident and well-known concept; after the nozzle has blown and an exchange is obtained on the film, there is a resumption through slits, between one nozzle and the other that let us obtain a minimum heating of the lower part of the film this way.

The suction carried out in this way solves the problems of drying and blowing off the films that have rigidity and a pull that is sufficient to recover the air from the same side.

Some films require other airways depending on the technology that the customer usually uses in his experience.

The suction from above is used in all lamination, coating, flexographic, and rotogravure printing processes and flexography and rotogravure processes. It has important effectiveness, especially when it is combined with perfection in the delivery.

The suction type from the upper side allows you to create a minimum path after blowing the air, thus minimizing pressure drops.

Rimor S.r.l. technology allows you to vacuum at low speed, avoiding the suction of the film.

The suction from below is usually combined with suction from above to keep the film well supported on the rollers and allows you to manage non-rigid films or supports that are decidedly difficult to work in any other way.

After it is blown, the air is usually not completely sucked in, in the sense that a portion of suction is always left from above, through the lower part of the furnace, which is connected to a suction branch.

Rimor S.r.l. Technology also allows you to have suction from below conveyed above to avoid having two separate pipes but to define the amount of air to be sucked from under the film or from above with a regulation in the hood.

In the RECUBE DRY Magica version, it has the possibility of sucking in a portion of air also from the side, therefore from the side in the same blowing hood.

The suction from below is usually used particularly in drying hoods or furnaces with the application of the coating or in any case with typically long and curved lines with straight segments with multiple hoods positioned humpbacked.

Lateral suction is a solution often used. The air is blown crosswise through the blowing nozzle and is then taken up from the sides through two side slits.

The air is brought back to the sides through the geometries of the blowing plane, which allows this path of air exit, through the ‘valleys’ that are sized to avoid a disturbance on the film.

The side suction system is used on blowing drying hoods or furnaces for lamination, laminators, coating lines, flexographic or rotogravure printing lines or machines with the combination of a portion of air from the lower part of the film wrapped.

The system is then optimized in the uniformity of air recovery with reduced speeds to avoid disturbances on the film. Side suction is preferable on films that require drying only from the top.

The side suction of drying or printing hoods are often used in laminating machines.

The Rimor single nozzle is a linear nozzle with a non-beak outlet but a flat part to increase heat exchange.

The single nozzle is usually positioned in correspondence with a roller to optimize the heat exchange and insist on the film to obtain a seal of the film so that it does not move in printing processes or even in long lines where the possibilities of displacement are greater.

The Rimor single nozzle is used in hoods, blow molding furnaces, drying furnaces, drying furnaces for flexographic printing, rotogravure printing or lamination, coating or lamination processes.

The technology of Rimor S.r.l. derives from fluid dynamics studies of considerable importance with an ability to produce nozzles that guarantee + – 1 m / s of precision in speed and + – 1 m / s in temperature.

The importance of perfection in blowing is essential to obtain performance, but equally important is the machine’s performance.

Rimor single nozzles can guarantee a perfect and uniform performance without internal bulkheads or perforated sheets that create pressure drops.

In the case of Rimor S.r.l. it is possible to make the nozzles with all the materials present and any coating, such as teflon coating, stainless steel, or aluminum.

The removable nozzles of Rimor S.r.l. are usually used in printing processes, laminating processes, laminating processes, coating processes, flexography, or gravure.

Printing machines or Printing & Converting machines often have processes where chemical components cause condensation in drying or water or solvent heat exchange systems.

The removable nozzles have the characteristic of being able to be removed from the drying hood or the printing machine, the laminator, or the coating machine to be easily cleaned or replaced.

The removable nozzles can be single nozzle, Coandă effect nozzle, or single Coandă + effect nozzle (triple outlet).

The nozzles are connected to the air-launch and return system through the air inlet and outlet nozzles with gaskets to ensure tightness.

Even the removable nozzles can be made with all available materials.

Drying hoods with Coandă blowing effect machines for laminating, coating, rotogravure, flexographic, are mainly applied to coating and laminating processes.

The Coandă effect blowing system is used effectively in hoods or floating drying furnaces and is a system where mainly a film support effect is obtained thanks to the particular geometry of the nozzles.

The Coandă effect conveys a double inclined airflow towards the center onto the film. In this way, a supporting result of the film is obtained, containing a drying film that must be ventilated or dried perfectly in the center without moving.

The drying system with the Coandă effect or support effect, the drying system allows you to spread, print, or laminate on both sides and be positioned vertically and horizontally.

The Coandă system can be used as a single blowing system or combined with a single nozzle (thus having three combined blowing nozzles).

Inspectable drying hoods are a simple and effective system of creating punctual drying hoods or furnaces, i.e., with nozzle, Coandă effect hoods, or diffused hoods with blowing holes.

The system was developed by Rimor S.r.l. to obtain easy access both to the blowing nozzles and to the recovery areas. In addition, they are drying furnaces or hoods or extremely flexible drying systems that allow easy construction and even easier disassembly of the parts in contact with the film to be dried or dried.

The system of inspectable ventilation hood or furnace for laminators, laminators, rotogravure machines, or flexographic machines is a blowing hood which, using a perfectly uniform flow (in fact, guarantees + -1 m / s and + – 1 ° C of uniformity of speed and temperature) creates a solution that is very low in terms of weight. In addition, the system is easily insulated and easily lifted by having the hooks on the four sides of the hood or furnace.

The system can be equipped with specialties such as teflon coating or AISI 304 stainless steel parts.

The Rimor S.r.l.  drying hoods or drying furnaces of the RECUBE DRY series is a highly compact and competitive machine with a single fan on board and is able to create the classic single fan circuit with three valves with the valve connected to the extraction, valve connected to the recirculation, and valve coupled between the suction and evacuation.

This execution then allows to insert the drying hood or furnace on board the heating module, which can be with burner or resistance or steam or hot water heating.

The system can be applied to lamination or rotogravure lines or drying lines in general such as painting lines or coating or flexographic or rotogravure lines in food packaging.

The integrated hood with a single fan applies to lines where several fans connect with the exhaustion and the extraction fan.

RECUBE technology, space optimization, internal speed reduction, precision, and the particular absorption screw application allow to obtain an optimal result as all RECUBE technologies are applied.

The gasket application system allows to overcome all alternative technologies such as welding or stapling, or silicone.

The drying hood or furnace with double fans allows to equip the laminating machines or printing machines or coating machines or spreaders or flexographic printing lines or rotogravure machines.

The drying lines with RECUBE technology allow to be particularly efficient and silent, having the minimum pressure drop.

The double fan dedicated to the delivery and one dedicated to the suction allows you to obtain the classic RECUBE circuit with only two valves instead of the traditional three valves, allowing for significant energy savings.

The system is efficient throughout the recirculation range from 0 to 100%.

This system also allows for heating using a coil or by a burner or diathermic oil or steam.

The incoming air is filtered and can be combined with a heat recovery unit.

The adjustable drying hoods are a system created by Rimor S.r.l. to solve the problem of drying, drying of the films in the coating or lamination that allows you to suck part of the air from above and convey it from below.

The phenomenon is known that for some types of films, aspiration exclusively from the top can create the phenomenon of lifting the film, which is damaged by touching the hood.

The system of Rimor S.r.l. it allows to avoid this phenomenon that occurs in the coating or the lamination for the less rigid films, going to aspirate an amount of air from below in an adjustable way, with the particular geometry of the lateral suction windows which, when closed, take air from double bottom that the customer creates in its base where the rollers and the mechanics are usually placed.

The Rimor RECUBE DRY adjustable drying hood or furnace is a technology that allows you to vacuum from the top as much as possible, reducing energy consumption and increasing efficiency.

The drying hood or furnace has an easily removable nozzle for easy maintenance.

The Rimor air blade is an innovative concept in drying furnaces and drying furnaces for lamination or rotogravure or flexography or coating.

The Rimor single ventilation blade realizes an entire drying furnace efficiently and economically, managing to guarantee maximum lightness and maximum savings combined with temperature precision of 1 degree and speed of 1 m/s.

The blowing hood consists of a delivery circuit and a recovery circuit where the latter can be reduced in flow rate by sucking up updates from under the film or increasing it to minimize the lower body’s heating.

In this way, it is possible to obtain maximum aeraulic and energy efficiency with minimum expense.

It is possible to combine the blowing blade with three delivery nozzles and one suction nozzle with wall suction.

Also available is the single blowing blade and double suction or the single blowing blade without suction so that the air is conveyed to the sides or under the film.

The single blade allows to obtain complete blowing and suction hoods that can be modulated in width and length.

In this way, we obtain hoods and drying ovens with removable blades.
