In our last blog post we went over the parameters of a customer project that required a portable sanitizing cart to be built in a fashion that would prevent the cart from carrying bacteria and other contaminants. As a leading manufacturer of cheese, whey protein, and other dairy ingredients our customer was concerned about potential bacteria being unknowingly brought in from outside. They hired the seasoned process design engineers at Placer Process to design and build a portable sanitizing cart to automatically spray the ground and floor workers’ shoes.
As we went over in our earlier blog post, Protecting Your Food, Beverage, Alternative Specialty Foods, Milk, or Dairy Facility Against Bacterial Contamination, not only did the portable sanitizing cart need to automatically disinfect the area but it needed to be constructed in a fashion that prevented it from carrying bacteria and contaminants itself. This required our team to take a non-standard approach to building the frame.
Standard construction for portable sanitizing systems usually use hollow square tubes welded together with any open ends sealed. In most applications this works great but given the amount of chemicals, heavy tank loads, and vibrations could potentially cause cracks over long periods of time.
As a preventative measure against such a scenario our process design engineers chose to construct the mobile sanitizing cart using only stainless steel flat bars. Even if there are cracks that form, there is no hollow chamber for bacteria and contaminants to hide – ensuring that the portable sanitizing cart is clean.
The sanitizing cart was equipped with a disinfectant solution storage tank, circulation pump, and assortment of valves. A proximity sensor was used to detect motion and triggering the disinfectant to automatically spray the ground and shoes of passing workers. We also used non-streaking corrosion resistant casters to prevent any marks from being left on the floor as the cart was moved around.
This is just one of many projects where our engineers go above and beyond to find a solution that fits the specific needs of the plant, and addresses all of the customers concerns. You can read more about this project via the case study here.
