Winegrowers Supplies  -  Internal bottle rinsers/sterilisers and drainers

I've heard recently that some 'large wineries' are not rinsing/sterilising bottles prior to filling, they are taking a significant risk. In Germany they do this occasionally but only by having delivery direct from the bottle manufacturer and filling the bottles within 7 days of manufacture, before there is much risk of contamination. This timescale is really not possible in UK. I believe that Environmental Health would not be happy if they knew what was happening. I have had pallets of bottles delivered from one of the major suppliers in London, long established and highly reputable, and on a couple of occasions I've found water in some bottles, having leaked in through the packing. That's why it is important to rinse/sterilise and drain bottles before filling.

Or:-

        DUR - SC1000  (up to 600 bottles/hour), 3,060 Euros

  Optional 0.45 micron membrane-cartridge filtering unit for the incoming water, 735 Euros

The operator places the first 4 bottles upside down inside the plastic cups on the top of the machine. Then he presses the green start button to open the valves. The water is injected automatically to rinse out any particles inside the bottles efficiently and quickly. The water dripping out is channeled into a discharge pipe.
While the first 4 bottles are dripping after rinsing, the operator places another 4 bottles on the remaining 4 cups.
The injection time is adjustable by means of a timer located in the machine control panel. Each section of 4 bottle-holders has its own timer, to adjust the rinsing timing separately.

or 

       DUR - SC1500  (500 to 1200 bottles/hour), 5,600 Euros

Designed for the internal washing of glass or PET bottles. It consists principally of a clockwise rotating table with 20 cups in which bottles are manually upturned and inserted.

The bottles are rinsed by an injection of pre-filtered water. The quantity of injected water can be adjusted according to requirements.
After rinsing, the bottles are allowed to drip for sufficient time to achieve a low residual amount of water. The speed is adjustable by the controller on the machine base.

Optionally the machine can be equipped in a 'sterilising version' (1,000 Euros extra) with a stainless steel recycling pump, a recovery tank for the solution and a microfltration unit. It can also be supplied in an air-blowing version.

A great advantage is the small overall dimensions and the 4 swivelling wheels for easy movement. Its base-frame and main parts are manufactured in AISI 304 stainless steel.

Using Sulphur dioxide (SO2) or Peracetic acid as sterilant?

Sulphurous acid is a colourless solution of sulphur dioxide in water, with the formula H2SO3, characterized by a suffocating sulphurous odour. It is different from sulphuric acid H2SO4.

Bryce Rankine states Sulphurous acid strength (in % SO2) against Contact time in seconds to sterilise an empty bottle:-
                                             0.5                                                                60
                                             1.0                                                                45
                                             1.5                                                                30
                                             2.0                                                                 5

Typically, 2% Free SO2 solution would be used as the bottle sterilising solution.

Peracetic acid, typically as a 1% solution, needs much longer reaction time in the bottle (at least 10 seconds), so the operation would have to run at one fifth of the speed (2 seconds contact time with SO2 is enough); a larger machine would hence be required for a particular throughput.

Peracetic acid is a very powerful cleanser and disinfectant; it's oxidation potential outranges that of chlorine and chlorine dioxide. In concentrated form it must be handled with great care; rubber or Neoprene gloves must be worn.
When peracetic acid dissolves in water it disintegrates to hydrogen peroxide and acetic acid, which will fall apart to water, oxygen and CO2, these degradation products are non-toxic and can easily dissolve in water.

SO2 is much more corrosive, so the complete machine must be in stainless steel AISI-316 rather than AISI-304. A vapour aspiration system is necessary.
