Static spray balls can’t always deliver the needed cleaning efficiency required. When more efficiency is required, upgrade to Toftejorg rotary spray head technology. Installation is simple; unclip the static spray ball and replace it with a new clip-on rotary spray head. As the spray head rotates, its fans produce a variable falling film, which has higher heat and mass transfer coefficients than the falling film produced by the static spray ball. This enables the optimization of cleaning procedures and significant savings on water, chemicals, and energy.

To achieve the best cleaning results, Toftejorg rotary spray heads use a spray pattern to ensure the dynamic and effective distribution of rinse water to the inner tank surfaces. The impact from the rotating fans and improved mass and heat transfer provide efficient residue removal after production. Self-draining and self-cleaning, inside and out, all Toftejorg rotary spray head devices comply with Good Manufacturing Practice (GMP).

Product benefits

Cost-effective cleaning

When higher cleaning efficiency than that offered by static spray balls is required, it is easy to upgrade to Toftejorg rotary spray head technology. Simply unclip the static spray ball and replace it with a new clip-on rotary spray head.

As the spray head rotates, its fans produce a variable falling film, which has higher heat and mass transfer coefficients than the falling film produced by the static spray ball. This enables the optimization of cleaning procedures and significant savings on water, chemicals and energy.

Efficient residue removal

To achieve the best cleaning results, Toftejorg rotary spray heads use a spray pattern to ensure the dynamic and effective distribution of rinse water to the inner tank surfaces. The impact from the rotating fans and improved mass and heat transfer provide efficient residue removal after production.

Self-draining and self-cleaning, inside and out, all Toftejorg rotary spray head devices comply with Good Manufacturing Practice.

An economic and environmentally correct choice

With perfectly flushed bearings and crevice-free design, Toftejorg rotary spray heads effectively clean tanks using less water, less energy and less cleaning agents than static spray balls. This not only helps reduce consumption of high-purity water and chemicals, but boosts your company’s environmental profile.

Performance reliability and long service life

Designed with minimal internal pressure loss, Toftejorg rotary spray heads rotate at pressures of less than 0.1 bar; however, the recommended operating pressure is between 2 and 3 bar. For over half a century, rotary spray head technology has proven successful in providing reliable and repeatable cleaning performance and a long service life.

Low maintenance, minimal downtime

Generally speaking, routine inspection is the only maintenance required for Toftejorg rotary spray head devices. These devices are so reliable that a single device in many cases can meet the requirements of a plant over its entire lifetime. No spare parts are likely to be needed for these devices.

High product integrity

To ensure product integrity, all Toftejorg rotary spray head devices are made of safe and non-reactive hygienic materials. All materials made of stainless steel are fully traceable in accordance EC No. 1935/2004. All non-metallic parts used comply with FDA requirements 21CFR § 174; non-metallic parts of rotary spray heads used for the Biopharm applications are certified in accordance with USP Class VI regulations. Upon request, 3.1 certificates can be supplied for those tank cleaning devices that meet the EN10204 standard.

Total peace of mind with complete documentation for validation

All equipment and components in the Alfa Laval BioPharm portfolio can be  supplied with Alfa Laval Q-doc, a comprehensive documentation package that provides full transparency of sourcing, production and supply chains as well as full traceability of all changes in material, manufacturing procedures or spare parts. This smoothes process validation by providing factual support to substantiate GDP (Good Documentation Practice) for every aspect of BioPharm equipment supply and provides customers with high-quality Alfa Laval products backed by a no-risk guarantee.

The Q-doc package comprises equipment manuals, product/performance test, quality and manufacturing procedures, relevant material certificates, traceability documentation, and the necessary parts and service information. This attention to detail maximizes uptime and minimizes risk.

ALFA LAVAL TOFTEJORG – SANIMIDGET RETRACTOR

The Toftejorg SaniMidget retractor is installed in places where fully automated and validated cleaning can assure higher productivity, due to less cleaning time in spray drying applications within the food, ingredients, and pharmaceutical industries. Larger ducts, channels, cyclones, chambers, complexed reactors, and vent lines can be cleaned to the highest standards, with no manual or semi-automated interference, avoiding any product carryover or hazardous incidents.

WORKING PRINCIPLE

The Toftejorg SaniMidget retractor is available with two styles of retracting mechanisms:

1. Pneumatic driven, which uses air pressure to extend and retract the cleaning head.
2. Media driven, which uses the pressure of the cleaning media to extend the cleaning head and an integrated spring to retract it.

The rotary spray head creates a fan of fluid in a swirling pattern. The distribution pattern of the cleaner head generates a vibrating impact as well as cascading flow coverage of all internal surfaces of the tank.
