Toftejorg SaniJet 20 Rotary Jet Head

Meets the Highest Standards in Sanitary Cleaning
Toftejorg SaniJet 20 Rotary Jet Head

Application

The Toftejorg SaniJet 20 is a sanitary, rotary jet head device that cleans in a 360° indexed pattern. Designed for permanent installation, the device is completely self-cleaning and self-draining and has an integrated self-cleaning downpipe (patent pending). The drive mechanism is located outside the tank or process equipment, leaving a minimum of parts to be submerged into the product. All product contact surfaces are either 1.4404 (316L) stainless steel or FDA-approved polymer materials.

The device is designed for use in pharmaceutical, biotechnological, food and dairy processing applications and is suitable for tanks and vessels between 0.5 and 30 m3 (130 to 8,000 US gallons). It is especially well-suited to processing highly viscous, foaming or thixotropic products and to chemical processing applications where product cross-contamination is unacceptable.

Sizing/selection and installation drawing are available in Alfa Laval CAS tool for Tank cleaning equipment.

Working principle

The Toftejorg SaniJet 20 utilises the patented “Golden Section” cleaning pattern (see back page). The distance between the tracks of the jets ensures efficient removal of residual product from the tank surface from the start of the cleaning sequence, allowing for quick, yet effective cleaning.

Standard Design

The Toftejorg SaniJet 20 is available in media-driven or motor-driven versions. Motor-driven versions are equipped with a magnetic clutch for leakage-proof transmission. The air motor provides an effective drive for low flow machines in rough environments and for use in explosive hazard zones, provided it is installed according to safety instructions. The air motor has variable speed to adjust cleaning intensity. The device is designed in accordance with the EHEDG design requirements for sanitary design of processing equipment. As standard documentation, it can be supplied with a “Declaration of Conformity” for material specifications.

TRAX simulation tool

TRAX is a unique software that simulates how the Toftejorg SaniJet 20 performs in a specific tank or vessel. The simulation gives information on wetting intensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning machine and the correct combination of flow, time and pressure to implement.

A TRAX demo containing different cleaning simulations covering a variety of applications can be used as reference and documentation for tank cleaning applications. The TRAX demo is free and available upon request.

Cleaning Pattern, the Golden Section

Toftejorg SaniJet 20 operates according to the patented Golden Section cleaning pattern (EP-Patent No.: 0495883, US-Patent No.: 5,279,675), which is unique in building up a uniform pattern. The pattern starts very coarse and refines itself in a step-less way by laying out the tracks approximately in the middle of the two most distant tracks already made. This means that the jets always clean the areas containing the most remaining product, and thereby remove as much deposit as possible in the shortest possible time. In some instances, this method of cleaning can even render a complete cleaning pattern unnecessary.

The Golden Section is the most suitable cleaning pattern for an effective pre-rinse.
