In industries like pharmaceuticals, biotechnology, and food & beverage, large fermentation tanks, mixing vessels, and reactors are indispensable. However, effectively cleaning these tanks, especially around internal obstructions like agitator shafts, has long been a significant challenge. These areas are notorious for creating "dead angles" – spots where traditional cleaning methods fail to reach, leading to residue buildup, potential contamination, and compromised product quality.
Our Automatic Tank Cleaning System introduces a standout technical feature specifically designed to conquer this persistent problem: its unique ability to clean different points on both sides of the stirring shaft, effectively eliminating cleaning dead angles without requiring internal modifications to the reactor.
Beyond 360° Rotation: The Ingenuity of Targeted Cleaning
Many automated tank washers boast 360° cleaning patterns, which are excellent for open tank spaces. However, a static 360° spray can still be blocked by large internal components like agitator shafts, baffles, or internal coils, creating persistent shadow zones. This is where our system's advanced capability shines.
Here's how this innovative feature works:
Intelligent Positioning and Movement: Unlike fixed spray balls or simple rotating cleaners, our system utilizes a mobile trolley as the carrier. This trolley integrates a sophisticated servo drive wheel and lifting system, telescopic system, and tilting arm system. These components work in synchronized motion, allowing the high-impact three-dimensional rotating tank washer to be strategically positioned inside the tank.
Dynamic Coverage Around Obstructions: Instead of relying on a single, fixed cleaning point, the system dynamically adjusts the height position and extends/retracts the washing hose. This allows the cleaning head to move around and past the stirring shaft. By setting specific cleaning points, the system can systematically target areas behind the agitator blades and shaft, ensuring that high-impact cleaning jets reach surfaces that would otherwise be perpetually shadowed.
Preventing Dead Zones without Internal Modifications: A common workaround for agitator-related dead spots is to install additional internal spray nozzles or rails within the reactor. This adds complexity, cost, and paradoxically, creates new potential dead spots or areas for residue to accumulate. Our system's intelligent positioning eliminates this need entirely. It leverages its external mobility and precise internal reach to clean thoroughly without any permanent internal additions to your reactor. This saves significant cost and, more importantly, avoids creating additional cleaning dead spots or surfaces that need their own cleaning.
High-Impact, Stable Cleaning: The core of this system is a high-impact, three-dimensional rotating tank washer, driven by water pressure to achieve powerful 360° rotation and revolution. This washer incorporates an advanced planetary gear reducer, which ensures a balanced power distribution and prevents any shaking or swinging during the cleaning process. This stability is crucial, as it avoids impact on the internal equipment (like the stirring shaft itself) and prevents damage to the tank washer, ensuring consistent and safe operation.
The Tangible Benefits: Efficiency, Purity, and Cost Savings
This specialized capability translates directly into significant advantages for your operations:
Guaranteed Purity: By eliminating cleaning dead angles, you drastically reduce the risk of microbial growth or cross-contamination from residual product, ensuring higher product purity and safety.
Reduced Downtime: Thorough cleaning on the first pass means shorter cleaning cycles (can be set from 5-20 minutes) and less need for costly manual interventions or re-cleaning.
Cost Efficiency: No need for internal tank modifications saves on installation costs, maintenance, and the complexities associated with adding permanent fixtures inside your reactors. Lower consumption of cleaning fluid is also achieved due to targeted effectiveness.
Enhanced Compliance: Achieving a truly clean-in-place (CIP) environment supports stringent regulatory compliance in highly regulated industries.
By intelligently navigating and cleaning around internal obstructions like agitator shafts, our Automatic Tank Cleaning System sets a new benchmark for comprehensive, efficient, and cost-effective tank hygiene.
