High-speed rotary bottle rinsing machine

01

Set the sanitizing medium, strength and contact time

US rules for bottled drinking water (21 CFR 129.80) require multi-service containers to be cleaned, sanitized and inspected just before filling, washed, rinsed and sanitized by mechanical washers or another adequate method, with records of the washer's maintenance and performance and testing of cleaning and sanitizing solutions. Minimum sanitizing treatments include steam or hot water in an enclosed system at 170 °F for 15 minutes or 200 °F for 5 minutes; chemical sanitizers equivalent to a 2-minute immersion in 50 ppm available chlorine at 57 °F, or at least 100 ppm when applied as a spray or fog; or 0.1 ppm ozone for at least 5 minutes in an enclosed system. [1]

If a sanitizer other than those permitted for food-contact use is used, it must be rinsed off, and the final rinse before filling must use disinfected water free of pathogens or an equivalent sanitizing step. [1]

Editorial calculation: 170 °F ≈ 77 °C, 200 °F ≈ 93 °C and 57 °F ≈ 14 °C. A spray rinser for sanitizing therefore needs at least 100 ppm available chlorine or an equivalent, double the immersion figure. [1]

Give the supplier the bottle types and sizes, output, rinse medium (water, ionized air, sanitizer), sanitizer type and concentration, contact time, water consumption and recovery, final rinse water treatment, CIP, and the regulations the line must meet.

02

Verify container cleanliness

The same rules call for filled containers to be inspected and require at least once every 3 months a bacteriological swab or rinse count from at least four containers and closures taken just before filling; no more than one of the four may exceed one bacterium per millilitre of capacity or one colony per square centimetre, and all must be free of coliforms. [1]

Editorial calculation: for a 500 mL bottle, one bacterium per millilitre of capacity is a limit of 500 per container rinse sample. [1] Ask the supplier how the rinser's nozzle coverage and drain time support these results on your bottles.

03

Choose water rinsing or ionized-air rinsing

Published machine descriptions show two rinsing methods. In a water rinser, neck or body grippers take the bottle from the infeed, turn it upside down over a spray nozzle that directs rinse water into it, let it drain and turn it upright; one rotary rinser-filler-capper builder lists 316 stainless steel contact parts and a 304 stainless frame. [4] In an air rinser, the containers turn upside down and pass over nozzles of pressurised ionized air, with the dislodged particles collected in the machine. [3]

Edelstein describes a non-slip gripper, adjustable rinsing pressure and time, a 'no bottle, no rinsing' option, a stop when the water tank runs low and a guard against crushing glass bottles. [2] Traktech states that its air rinsers clean glass, plastic or metal containers and that ionized air removes particles held by static electricity. [3]

Editorial calculation: 3,600 bottles per hour on 12 heads is 3,600 / 12 = 300 bottles per head per hour, or one bottle every 12 seconds per head, which is the time budget for gripping, inverting, spraying, draining and righting; 66 to 400 bottles per minute equals 3,960 to 24,000 bottles per hour. [2] [4]

Editorial note: an air rinser does not apply a sanitizer, so if your bottles must be sanitized before filling under the rules above, a liquid rinse or sanitizing step is still needed; state the medium per station in the order. [1]

State the medium for each station (water, sanitizer, ionized air), number of heads or grippers, rated output per bottle size, gripper type (neck or side), and the interlocks required (no bottle no rinse, low tank, glass breakage).

Fill the specification fields with values for your line

A rinser quotation needs values for your bottles and sanitation plan. The table explains each field, gives published values where a reviewed source states them, and says what to obtain from the supplier.
