Description

ProClean Conveyor (PCC) — definition: The HECHT PCC is a pneumatic vacuum conveyor that transfers powders and bulk solids dust-free in a closed system between process equipment, such as reactors, granulators, dryers, blenders and centrifuges, and containers such as drums, big bags or sacks. It is built to hygienic design principles and available in WIP, CIP and ATEX versions.

Key points — ProClean Conveyor (PCC)

Containment: closed conveying without an open transfer step, also for toxic substances and explosive fine dust
Cleaning: available in WIP and CIP versions; tool-free filter change without dismantling pipes or cables
Conveying: horizontal and vertical over long distances, also for products with high residual moisture or high density; adjustable from fast dilute-phase to gentle plug conveying
Versions: FDA- or ASME-compliant, pressure-resistant according to PED 2014/68/EU, ATEX versions and inert (oxygen-free) conveying
Filter technology: durable ring filter technology with a large filter surface; filter head can also be retrofitted

The HECHT ProClean Conveyor "PCC" is a powerful vacuum conveyor and innovative pneumatic conveying system for bulk materials, specially developed for the gentle conveying of powders in sensitive production environments.

This efficient conveying system for powders reliably connects value-adding machines such as reactors, granulators, dryers and mixers. The pneumatic conveyor for powders is ideal for clean transfer into containers, drums, big bags or sacks - even with explosive or toxic substances.

Thanks to its flexible design, the PCC can be integrated into industrial processes in a variety of ways. The combination of an innovative filter head, high conveying capacity and dust-free conveying makes the PCC the first choice for companies with the highest demands on safety, efficiency and containment.

Frequently asked questions about the ProClean Conveyor (PCC)

What is the ProClean Conveyor (PCC) and why is in-process cleaning revolutionary?

The PCC is a closed-system conveyor with integrated CIP facilities for safe powder transfer. It's revolutionary because: (1) it eliminates separate cleaning stations, (2) it minimises downtime between batches, (3) it improves hygiene accuracy, (4) it's a self-validatable process.

How much time do I save with in-process cleaning?

Considerably. Standard batch changeover: 30–45 min (transfer + separate cleaning). PCC: ~20 min total (transfer + integrated CIP). For 50+ batches/week this means massive downtime savings.

How does the CIP injection work?

An integrated injection unit sprays water or detergent onto the conveyor belt. A vacuum-recovery system extracts everything. Automatic cycle: ~15 min. No manual cleaning required.

Is the PCC GMP-compliant?

Yes. GMP Annex 1 compatible, GAMP 5 validation available. CIP protocol fully documented. Stainless steel construction, pharma-grade. Validation: 4–6 weeks.

Which powder types can I use the PCC with?

All types: fine powders, crystals, granulates, bulk materials. OEB 1–5 compatible. Speed adjustable for different product characteristics.

Can I expand the PCC?

Yes. PCC Modular variant: fast modular expansion. Standard 500 mm or 800 mm width. Length expansion via flange connectors.

How much product loss occurs?

>99% product recovery. The vacuum-recovery system captures all material and cleaning liquid. Zero waste-to-drain.

How much maintenance does the PCC require?

Minimal. Monthly inspection of conveyor belt tension. Annual CIP nozzle replacement. Standby mode between batches — no downtime.
