Centrifugal drying accelerates conventional drying in two stages. First, high-speed rotation uses centrifugal force to spin off excess liquid from the workpiece surfaces. Next, an integrated heating system circulates hot air inside the chamber to remove remaining moisture, while a turbine fan extracts humid air to maintain efficient airflow and consistent drying.
This high-intensity process delivers fast results—typically producing dry, clean parts in around five minutes, depending on part geometry and load conditions. Inovatec offers ten centrifugal dryer models to match different capacity and application requirements.

Which Inovatec dryer is right for your process?
Inovatec supplies three types of drying equipment for mass finishing operations. They are not interchangeable — each is designed for a specific situation. Use this table to identify the right fit before going further.
| Centrifugal Dryer (SK) This page | Vibratory Dryer (VD) | Spin Dryer (SK35A/70A) | |
|---|---|---|---|
| Drying method | High-speed centrifugal spin + hot-air heating | Heated corn cob media (vibratory bowl) | Spin + 3 kW heating element |
| Capacity | SK400B: 35 kg / SK500B: 75 kg — 10 models total | VD200A: 200 L / VD600A: 600 L | SK35A: 35 kg / SK70A: 70 kg |
| Compound residue removal | Good — hot-air + spin removes surface chemistry | ✓ Best — corn cob absorbs compound film | Limited — spin removes water, not compound film |
| Cycle time | ~5 minutes (fast industrial drying) | 10–20 minutes (batch mode) | 5–10 minutes |
| Automation integration | ✓ Conveyor/continuous models available | Batch + continuous feed modes | Batch only |
| Primary market | Industrial production lines; electroplating; metal parts at medium–high volume | Post-vibratory finishing; compound residue removal | Electroplating workshops; small batches; de-oiling |
| Best for | Fast drying at volume; heat-sensitive parts (no-heat model available); continuous production | Parts with compound film after wet finishing; polish-and-dry in one step | Low-cost entry; plating workshops; small batch de-oiling |
The SK series centrifugal dryer — what makes it different
The SK series centrifugal dryer is the industrial workhorse in the Inovatec drying range. Its defining characteristics are speed, capacity range and compatibility with automated production lines. Parts come out dry in approximately five minutes. The stainless steel basket and chamber withstand aggressive industrial use; the interlock lid-safety system prevents motor start with lid open. Ten models cover different capacity requirements from small-workshop to high-throughput production.
The two-stage drying mechanism — centrifugal spin to throw off bulk liquid, followed by hot-air heating with turbine fan extraction to remove residual moisture — achieves thorough drying that spin-only or heat-only methods cannot match. For heat-sensitive parts (plastics, soft alloys, coated parts), the heating stage can be omitted; the spin alone removes the majority of surface water.
SK series model specifications

10 total models available. Working temperature 50–80°C. Contact us for full model range specifications.
Who the SK centrifugal dryer is built for
Industrial production lines drying parts after wet finishing or washing — vibratory finishing, centrifugal disc/barrel finishing, rotary tumbling, rinsing, electroplating. The ~5-minute cycle time matches the throughput rate of most production finishing machines. Parts move from finishing to dryer to next process step without waiting.
Electroplating workshops — parts coming out of the plating tank carry plating solution. Slow drying causes water spots and staining on plated surfaces; the SK centrifugal dryer removes surface liquid fast enough to prevent spotting before parts reach inspection and packaging.
Operations with heat-sensitive parts — the heating element is optional in operation. Running spin-only (no heat) makes the SK centrifugal dryer suitable for parts that cannot tolerate heat: soft plastics, rubber-bonded components, thin-wall non-ferrous castings. The vibratory dryer (VD series with corn cob) is an alternative for parts that need compound residue removal as well as drying.
High-volume operations needing continuous drying — Inovatec offers continuous-feed centrifugal dryer configurations where parts are conveyed in and out continuously rather than batch-loaded and unloaded. Contact us for continuous-feed model specifications.
How the centrifugal dryer fits into the finishing line
The complete mass finishing post-processing line for wet finishing operations typically includes separation and drying, and may include wastewater treatment. The centrifugal dryer handles the drying stage. Depending on the part type, a separator is needed upstream to separate media from parts before drying.
| Stage | Equipment | Notes |
|---|---|---|
| 1. Finish | Vibratory / centrifugal finishing machine | Parts come out wet with process water and compound |
| 2a. Separate (non-ferrous) | Vibratory separator (VS series) | Separates media from parts by size — use for aluminium, brass, plastic parts |
| 2b. Separate (ferrous) | Magnetic separator (MS series) | Separates media from ferrous parts by magnetic attraction — use for steel, iron parts |
| 3. Dry | SK centrifugal dryer (this page) | ~5-minute cycle; parts exit dry and ready for next process |
| 4. Wastewater | Automatic wastewater centrifuge | Optional — processes effluent before discharge |
Key selection factors when choosing a centrifugal dryer
| Factor | What to specify |
|---|---|
| Capacity | Match dryer cycle capacity to your finishing machine batch size and cycle time |
| Heat sensitivity | Specify if parts cannot tolerate heat — heating element can be excluded or disabled |
| Batch vs continuous | Standard models are batch-loading; continuous-feed configurations available for automated lines |
| Drainage | Confirm drain outlet position and whether pump-assisted drainage is needed for your installation layout |
| Noise | High-speed operation generates noise; specify if low-noise design is required |
| Power supply | Three-phase supply required; confirm voltage at order stage |
