Chemical vs. Hot Water Sanitizing
Both types of sanitizing method are using in sanitizing dishes. Here we will present you their advantages and disadvantages.
The benefit of chemical sanitizing appliances is that the temperature, can be set at a lower setting (120° F), and your energy bills will be less expensive. A chemical agent commonly contains chlorine that has injected into the washing device after the cleaning process and during the final rinsing operation.
The expenses of the chemicals you chose to use is generally the biggest investment besides the dishwashers. The FDA also requires that you provide test strips on the site regularly maintain and verify that your device is using an adequate amount of chemicals for proper sanitizing. Too weak or too strong chemical sanitizer in your appliances can produce undesired results such as unsafe dishes or strong chemical flavorings.
To avoid stress while mixing water and sanitizer in order to achieve perfect balance you can try Swing Mark. This sanitizer valve automatically controls portion of detergent and sanitizer and that way sanitizing solution is always at the optimal level.
Hot Water Sanitizing
Opposite to chemical sanitizing, hot water sanitizing needs the use heat to sanitize dishware. Disinfecting water should reach 171 degrees F to achieve suitable levels of disinfecting, and your energy bill will be cheaper.
Test the efficiency of your appliance to make sure that it complies with sanitizing regulations. Food inspectors will typically control the plate temperature, before then water temperature directly, because this can be difficult to perform while the device is running. After the adequate heated rinse cycle, plate temperature should be at 160° F or higher. A dishwashing thermometer or heat tape can be placed during the cycle to check the proper temperature.
Sanitizer Test Strips
A significant part of food businesses is proper sanitizing of equipment. Typically, chlorine (bleach) or quats (quaternary ammonium) are used to destroy harmful bacteria on serving utensils, food-contact surfaces and other items used for preparing food. Sanitizing agents only work if used correctly and that’s why food services are required to have test strips to check sanitizer. Test strips should use in 3-commercial sinks or low- temperature dishwashers. The 3 most common sanitizers are chlorine, quaternary ammonium and iodine. The type of test trip required depends on the type of sanitizer used.
- Chlorine test strips a ranging from 0 ppm to 200 ppm (parts-per-million).
- Quaternary ammonia test strips (quats) ranging from 0 ppm to 500 ppm.
- Iodine test strips ranging from 12.5 ppm to 25 ppm.
Chlorine Test Strips
Chlorine (bleach) is one of the most frequently chosen sanitization techniques. This product is widely available and cheap, but also contains a distinctive odor that can be unpleasant if it keeps on dishes.
Besides that, bleach loses its sanitizing capacity rapidly as it has exposed to oil and organic materials, which can cause it less effective if the sanitizing sink becomes contaminated. A chlorine sanitizer should have a concentration of 50 to 100 ppm in water between 75° and 100° F, with a needed contact time of about 7 seconds.
Chlorine test strips are adequate to help you to ensure the suitable solution has made. You dip the paper in the water, and you’ll see it becomes a shade gray that can be compared to a scale with the test strips, with most scales ranging from 10 to 200 ppm.
Quaternary Ammonium Test Strips
Quaternary ammonium (quats) sanitizes dishes by using its positively charged cations to link with the negatively charged particles of unwanted pathogens. Quats are often chosen over chlorine chemical since it’s noncorrosive, and it won’t pit stainless steel over time.
Also, ammonium is nonirritating to skin, because it has similar properties as detergents, it can stand more soil than chlorine before it requires to change. Anyway, quats frequently don’t work well in hot water, making testing a necessary part of any quats sanitation process.
Quats test paper measures the concentration of the quats sanitizer in the water, applying a color scale ranging from 0 to 500 ppm. You can find this test paper in pre-cut strips and tear-off rolls. Most quats sanitizers need solutions of 150 to 220 ppm in water that is at minimum 75° F, with the dishes dipped about 30 seconds.
Iodine Test Strips
Although, iodine isn’t common such as chlorine or quats, has some advantages for restaurants that decide to use it. This sanitizer is brown, with the color demonstrating the strength of the solution, which can discolor some items. It isn’t affected by the hardness of your water.
Although iodine isn’t long-lasting as quats, it lasts longer than chlorine in contact with organic compounds. It’s also better for skin than chloride, but not so gentle as quats. This sanitizer solution should be used at 12.5 to 25 ppm in water that is about 75° F, but not more than 120° F.
Iodine test strips are suitable to make sure this solution is kept at an adequate dilution since the color alone isn’t sufficient to determine the level.
