Alfa Laval Toftejorg - SaniMidget Retractor

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).

Application

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.

Standard Design

The Toftejorg SaniMidget retractor is available in three stroke lengths: 100 mm, 150 mm, and 250 mm, in either pneumatic-driven or media-driven versions.

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.
