Bacteria Traps

Bacteria Traps

 

devices to trap microorganisms suspended in air in order to determine the extent and nature of bacterial contamination of the air in hospitals, homes, and industrial areas. In traps of Iu. A. Krotov’s system, air is drawn through a slit and then strikes a revolving Petri dish with a solid nutrient medium. In other traps, air is drawn through a liquid (water, nutrient broth) or dry (cotton) absorbing medium. In traps of S. S. Rechmenskii’s system, bacteria are absorbed by small drops of sprayed liquid which settle on the walls of the device. Contamination is determined by cuituring the liquid (or dry medium) that traps the microbes on nutrient mediums.

Features include upgraded seals and gaskets, angled surfaces for rapid wash down and water run off (ensuring faster drying times) and reduced crevices in bushings and hoppers, which help to eliminate bacteria traps. As a result, the RV weighers installed at Tulip offer maximum hygiene while minimising downtime for cleaning.

Sani-Pallet[TM] eliminates sidewall seams, gaps, holes and other bacteria traps. Sani-Pallet[TM] also features built-in Microban[R] antimicrobial protection for an added layer of protection against odor-and stain-causing bacteria.
The 1P67-rated hygienic design incorporates six degree sloping, self-draining feeder covers and a nine degree sloping, self-draining main body, which minimise bacteria traps and allow faster and easier cleaning to increase uptime.

Ease of access to thermoforming and sealing tools facilitated by sliding guards and hinged upper tooling; Upper tooling can be opened and closed in less than 10 seconds thanks to the Mecaplastic patented auto-locking system; rapid changing of moulds and sealing plates (less than 5 minutes down time); Complete change of format is possible in a time comparable to that of a sealing machine; No special tools required; measurable improvement in the overall production line operating efficiencies; multi-purpose cutting systems; cutting by compression therefore no adjustment when changing film thickness; easy cleaning, designed to have no bacteria traps; operating rates of up to 20 cycles/minute.
According to Cough, this helps to eliminate all potential bacteria traps, and a fully developed and proven integral 'wash and dry' system.
They provide easy clean surfaces and eliminate potential bacteria traps without the need for the time-consuming and costly concrete-cast kerbs being used at the floor/wall joint.
