For the stain free drying and secondary polishing of the trowalized work pieces with the use of heated media.

Functional principle - The induced vibration generates a gentle rolling movement of parts and drying medium.  The moisture on the parts is absorbed by the heated drying medium.  The constant relative movement between parts and medium has not only a drying, but also a polishing effect on the parts.

Technical features

• Helically shaped work channel without built-in ramp allows gentle component movement..
• Rubber-lined in feed chute built into outer wall of the work bowl facilitates the loading of finished components coming from the machine(s).
• Infinitely adjustable heating system with extremely heating performance.
• Heating system with replaceable heating rods which are mounted in the non-vibrating machine base.
• Integrated screening device allows batch as well as continuous processing.

Special equipment

• Pneumatically activated screening device facilitates the linking with production stages prior to and after drying.
• Dust cover with integrated suction fan and dust collector.
• For drying of extremely delicate components, the work channel can be lined with polyurethane. In this case, the drying process takes place with a hot air blower mounted at the top of the work bowl.
• Drying of work pieces with hot air only (without drying media).

Model Range DLT-driers

For gentle, stain free drying of extremely dished components with the use of heated drying media.

Applications - After the finishing process, the finished, but wet parts must normally be dried. With Trowal rotary drum type driers of the model range DLT, the parts are gently and stain free dried in a heated drying medium consisting of maizorb, ground walnut shells or wood chips.

• For large quantities of small parts, e.g. flat bulk parts.
• Especially suited for drying of cup-shaped parts.

Functional principle - The parts are transported through a rotating screen drum in continuous mode.  The drying of the parts takes place with heated drying medium.

Technical features

• Electrical heating with replaceable heating rods. Infinite temperature adjustment.
• Built-in rotating screen drum for separating the parts from the drying medium.
• Automatic return of the drying medium to the heating zone.
• Travel (heating) time adjustable from 2 to 4 minutes.
• Continuous operation facilitates the linking of the drying process with production stages prior to and after drying.

Special equipment

• Extension of screen drum for removal of drying medium from parts with extreme cavities.
• Dust extraction
• Air knift for removal of dust particles and drying medium form the dried parts
• Increased heating output

Model Range BF-HL-driers

For drying of the work pieces with hot air. For delicate parts, which should not impinge on each other.

Applications - Normally, the processed work pieces have to be dried after the finishing process. Trowal hot air belt-driers are designed to dry the work pieces with hot air. Most suited for components, which may not impinge on each other.

• for components with difficult to reach cavities where drying medium may lodge, and
•  long and bulky parts.

Functional principle - The components are transported through a drying tunnel on a wire mesh belt. The drying takes place with hot air which is constantly circulated with a blower fan uniformly heating the drying tunnel.

Technical features

• Optimum drying conditions by Infinitely adjustable operating temperature and Infinite speed adjustment of the belt drive
• Little energy consumption by substantial heat insulation (> 100 mm).
• No noise protection required!

Special equipment

• Wire mesh belt at choice from stainless steel (V4A).
•  High pressure air knife to blow off moisture or water pockets from the components.  Mounted over the belt at the entry to the drying tunnel.

Special design - Elongation of the transport belt for better loading resp. discharging of the work pieces.
