Kohlhoff Hygienetechnik, Unna, has developed various compact hygienic sluices for food processors. The SL- and HD-Lines can be equipped with tamper-proof components for cleaning, disinfecting, and drying hands, boots, and shoe soles.
The SL-Kompact hygiene sluices have been designed for plants where up to 40 people per shift pass through the system. This line includes the DLSO-SL1500 + EK400 WRT model, which combines three components for hand cleaning, drying, and disinfection with a turnstile and module for dry or wet shoe sole cleaning and disinfection.
In the sensor-controlled and contactless washing area, the soap is dispensed first. Afterwards, clear water runs for another eight seconds. This factory-set default can be individually adjusted, however, via the processor control. In the next step, the high-speed dryer equipped with a residual water drain dries the hands thoroughly and in an environmentally friendly manner in ten seconds. The optimally adjusted airflow is activated after the sensor detects both hands. The turnstile releases only after two-handed disinfection. When passing the hygiene sluice, the shoe soles are wet cleaned and disinfected by two rotating brushes. A multifunction display shows the various steps, and depending on the system equipment, reports critical fill levels of liquid soap, disinfectant, and cleaning agent. The turnstile can be rotated freely in the event of a power failure.
The compact hygiene sluices in the HD-Line have been built for companies with more than 40 persons per shift change. According to the manufacturer, they feature extended splash protection in the sole cleaning area and a robust turnstile in the entrance control unit. This includes the Cleancontrol HD compact hygiene sluice, which is equipped with a separate entrance and exit. The entrance can be equipped either with a tray for disinfecting shoe soles and a downstream drip grate, or with a brush cleaning module. The integrated EK 800 entrance control unit ensures foolproof two-hand disinfection. The exit contains an obligatory mechanical turnstile.
With transport, lifting, or shelf trolleys, wheels or rollers are usually the weak link in terms of hygiene. When moving from unclean to clean areas, their cleaning is often non-existent or inadequate, making them an often-neglected contamination risk. To address this issue, Kohlhoff has developed a lift truck wheel cleaning machine.
Designed for floor installation (requiring a depth of at least 250 mm), the system has four brushes mounted under a stainless-steel grate, each 700 or 1,100 millimeters long. Depending on the room and passage width, sensors are mounted either on the wall or floor at the entrance and exit. They activate the rotating brushes and then automatically spray them with a mixture of water, detergent, and disinfectant. This thoroughly cleans the wheels or rollers. To prevent snapping or jamming when rolling over, the stainless-steel grating is set up diagonally at a 45-degree angle to the direction of travel. The system can also be used for cleaning shoe soles.
