Hi

I am an olive grower and processor in Central Otago in the South Island
of New Zealand.

I operate an Oliomio 50 press and would like some feedback on a suitable
cleaner/sanitiser for use on the machine. Degresan, produced by S C
Johnston Professional Australia Pty Ltd has been recommended as a
suitable product. The active ingredients are sodium metasilicate and
alkyl dimethyl ammonium chloride. If any members of the group have had
experience using Degresan or a similar product I would be very keen to
hear their comments.

Many thanks

Cheers

Hi,

We have been running an Oliomio 50 for three years and clean it daily with
firstly cold water, hot water can make the crushed pits swell and block the
decanter, we then clean with hot water and then weekly with a 10% solution
of caustic soda followed by lots of water.

Cheap and effective

Regards

Mike

I have used the Oliomio 100 the 250 and now have the 350.
I contract process about 60 tonnes of olives per season.
I clean my machinery with hot water under pressure from mains water into a
small nozzle and have no problems with odours or greasy film
I am always very careful that I thoroughly remove all broken olive stones as
these can block the decanter and augers.
I understand from my supplier of cleaning products that sanitisers can only
be used after thorough cleaning and must then be rinsed off.
Which seems a bit of a waste of time and cleaning material.
Best of luck

Hi Mike

Thanks for your helpful comments. At the end of each day's processing I have
been washing the machine with hot water to remove the solids and any oil film.
At the end of last season I used Down to Earth dishwashing detergent to
thoroughly remove any remaining oil film. The detergent foamed badly which
made it difficult to rinse all traces from the machine and it was perfumed
which made me nervous about tainting the oil the following season.

As a result I was looking for an alternative and a friend who was a master
brewer had suggested an alkali or silicate for degreasing and quarternary
ammonium salts to sterilise.

Again many thanks.

cleaning with hot water.

How extensive are people cleaning between loads with the smaller olimio's?
I've found that unless I wash out properly that while crushing and malaxing
the remains from the last load go "off" and clog the machine on me when
extracting the next load. Suggestions please.

Hi,

We are using the Oliomio 50 and if we press every day and I am pressing the
same cultivar then I only empty the machine of Saturday evening.

I don't receive olives on Mondays as it means they were picked on Friday and
therefore to old, so we press Tuesday through Saturday.

The machine rests on Sunday along with me and I clean it out on Monday

If there is a gap at any stage of more than half a day I flush the machine
out completely with cold water and then hot water. If I use hot water first
the Oliomio decanter gets jammed because the crushed pits swell in the hot
water.

Hi Matt

I operate an Oliomio 50 pressing my own olives and providing a contract
pressing service to other growers. At the end of each day and between runs for
different growers I stop the decanter and replace all of the grubscrews. I
then re-start the decanter and spray hot water through the hammer mill and
brush or wash off all solids adhering to the malaxing unit. I also jet hot
water into the feed screw to the decanter to wash through any remaining
solids. The washing continues until the water discharging from the waste screw
runs clear. I then stop the decanter, remove the level 1 grubscrews and repeat
the washing until the water running out of the oil spout runs clear. This
process takes about 20 minutes in total.

If the machine is not going to be used the next day I will also remove the
guard and the screen from the hammer mill and wash all remaining solids from
these. I have found that the scraper bar and spraying water through the hammer
mill do not remove all of these solids. Dismantling the guard and screen,
cleaning them and re-assembling them takes about 10 minutes.

I hope that this helps.
