Kronen DECONWA Prep – Advanced Decontamination and Washing for Fresh Produce

CBS Foodtech proudly supplies the Kronen DECONWA Prep Decontamination and Washing System, a market-leading solution engineered for high-throughput, high-care fruit and vegetable processing environments. Designed to set the benchmark for food safety and operational efficiency, the DECONWA Prep uses advanced wet decontamination technology to prepare whole produce for further processing, reducing the risk of cross-contamination and ensuring every batch meets stringent quality standards.

Superior Decontamination and Washing:
By introducing hygienising additives such as chlorine or peracetic acid into the wash water, the DECONWA Prep significantly lowers the germ, virus, and bacterial load on product surfaces. This step is critical for processors looking to extend shelf life, enhance product safety, and comply with food industry regulations.

Versatile Product Handling:
Capable of processing a wide variety of both floating and sinking products ranging from 20 mm to 400 mm in diameter, the DECONWA Prep features intelligent flow control via a flexible baffle plate. Floating items are gently propelled towards the outfeed, while heavier products are efficiently transported by the water flow—maximising throughput and reducing manual intervention.

Seamless Production Integration:
With its automatic outfeed link belt, the DECONWA Prep is designed for uninterrupted transfer between production zones, making it the perfect solution for moving products from low-care to high-care areas. The machine’s compact footprint and adjustable settings enable easy integration into new or existing lines, helping processors boost capacity without expanding their floor space.

Productivity and Performance:
The DECONWA Prep delivers industry-leading productivity, with the capacity to process approximately 1,000 kg of apples per hour (based on a cycle time of 4.5 minutes). Controlled retention time ensures every batch receives thorough decontamination, while the rain shower and fresh water shower systems guarantee complete product coverage and effective residue removal.

Easy Cleaning and Maintenance:
Maintenance is streamlined thanks to suspension elements for removable parts, granting easy access for cleaning and changeover. This means reduced downtime and consistently high operational reliability.
