Blentech Clean-in-Place (CIP) Solutions
Cleanability is critical in food processing. At Blentech, we design equipment that makes sanitation faster, more consistent, and easier to validate. Cleaning is not just a maintenance task — it directly affects your uptime, audit performance, and product safety. Our systems turn sanitation into a predictable, repeatable process so your facility is ready for inspection every day.
Understanding the "Clean Assist" Foundation
Our standard equipment design incorporates a "clean assist" package, featuring a rotating spray ball system designed to effectively clean the majority of the system.
This involves strategically placed spray balls delivering cleaning solutions to accessible product contact areas. This balanced approach provides a cost-effective solution meeting industry standards without capital expenses for a fully automated system.
The Science of Soil Removal
To ensure the vessel is technically "dry" and free of microbial growth, our systems utilize two primary mechanical and chemical principles:
Overcoming Manual Cleaning Challenges
While "clean assist" handles the primary cleaning tasks, certain components typically require manual attention. We offer specific engineering upgrades to move toward full automation and eliminate manual "touch-up."
1
Shaft Seals:
Eliminating the Achilles' Heel
In a standard configuration, shaft seals require a daily manual check where the outer housing is removed to wipe down the shaft and seals before reassembly.
- The Standard: ~30 minutes for four seals (manual disassembly).
- The Upgrade: CIPable Seal. An endplate-mounted seal that can be cleaned in place without disassembly using attached cleaning fluid lines.
The Technology: Proprietary DiscSealâ„¢ technology is available for mechanical face sealing, eliminating the deep crevices associated with traditional packing glands.
2
Cover Gaskets:
Preventing Ingredient Accumulation
Standard gaskets seal against a flat top lip. During loading, ingredients may collect on this surface, requiring manual wiping.
- The Challenge: Wiping the seal surface manually can take up to 30 minutes.
- The Upgrade: Widened Gasket & Custom Hatches. We modify the cover assembly to utilize a gasket that extends over the top surface. Ingredients are introduced through access hatches, avoiding buildup on the edge and reducing cleaning requirements by ~95%.
3
Discharge Doors:
Contained Cleaning Environments
Standard discharge doors are typically manually wiped or washed down while in the open position.
The Upgrade: Removable Cleaning Hopper. A "plug-and-play" system with built-in sprayballs that replaces the discharge guard. It captures cleaning solutions and residue, preventing spills and cleaning the exterior surface of the door automatically.
Targeted ROI and Efficiency Summary
We offer these enhancements so you can choose the level of automation that aligns with your operational needs and budgetary considerations.
| Shaft Seals | 30 Minutes | CIPable Seal | 5 Minute Cleaning Cycle |
| Cover Gasket | 30 Minutes | Widened Gasket | 95% Reduction in Product Buildup |
| Discharge Door | 20 Minutes | Cleaning Hopper | Fully Contained / Automated Clean |
Technical Insight: U-Shaped Vessel Geometry
The foundation of Blentech cleanability is our U-shaped mixer body design. To maximize hygiene, we radius and inspect every corner, eliminating sharp crevices. This geometry facilitates full drainability, ensuring that gravity acts uniformly to funnel liquid and debris toward the discharge point, mitigating the risk of biofilm formation in stagnant pools.
