Plastic boxes are widely used in the food industry nowadays for storage of packed food products.
These boxes are washed and than used again.
Can anybody tell me what microbiological state to expect after washing and how wear and tear is of influence on this.

Dear All:

I quoted this enquiry by searching in the past topics here , and the above mentioned question is the same what I want to ask with a little different , Actually we are using plastic baskets in our catering facility for keeping the vegetables and fruits in order to storing them chiller ,and we observed that it is a bit difficult to wash them manually as we followed and the sanitation procedure will not be effective as well. So how to find a machine which can wash and sanitize these boxes or baskets at the same time (plastic baskets washing machine? If you know a company selling this machine?

B.Regards

A tray washer would normally be your best bet, they're a travelling washing machine operating at high temperatures (if the plastic can stand it). Sorry I can't think of any manufacturers but I would steer clear of the washers which look like dishwashers on steroids, ime they're not all that good and the travelling washers have the benefits of normally including an air knife (to push off excess water), higher temperatures and a clear demarkation between clean and dirty.

IWM (Industrial Washing Machines), Newsmiths Stainless and Unitech are the three main Tray/Crate washing machine manufactures in the UK ( We have several machines for our Business usage), they do all sizes of machines for small to large jobs. If not there is alway the option to get the trays/Crates washed at a Third party wash plant.

Thanks Mr P.

Try using Douglas Machines Corp.

Oliver Douglas and Bruel are other manufacturers I have seen.

None of these machines is very cheap and you need to do your calculations carefully.

Depending upon your volume of trays, contract washing through a pooling system like Chep may be an option

In the past I've had experience with a Newsmith washing machine for plastic baskets/trays and I was very pleased with its performance.
But depending on the required capacity for your wash process it may not be justified to invest in such anexpensive machine.
In the company I am currently working we also needed to wash plastic trays which are used for transporting fresh vegetables.
For about 2000 trays per week I decided to design a washing room (made of panels) and we also bought a high pressure cleaning machine (~ 190 bar, hot water). We now use this construction and we are very pleased with the results. The cost of the room was less than 5000 Euros.

Maybe an idea?

Dear Yannis,

Sorry for question, but does that machine wash trays itself, or workers wash trays with high pressure water spray coming from a machine?
Sounds like a very good idea. I'm trying to imagine how the whole process is happening in your new construction

Dear Inesa,

The trays are washed in this room by one worker who is using high pressure water spray created by a portable machine (Nilfisk)
Also a detergent and or sanitizer can be added in this machine.
The area of the washing room is 3x3 m

@Inesa - Yr new avatar is rather disturbing. Only thing missing is a larger horn on top and a spiky tail. A female Grinch perhaps ?.

Dear Yannisg,

Thanks for explanation. I'm just wondering about water temperature? What kind of protective clothing your employee has?



Dear Charles,
you don't like my avatar???!!! My cat family?
Or you mean my profile picture? It has a story. We've been visiting Danish Crown slaughter. This picture was taken after I saw pigs being slaughtered (about 10.000 a day if I remember correctly). I was so sad after some scenery I saw... And finally girls were taking pictures, a la "rapper" or something funny as we looked strange in those visitors clothes. I wanted to be the "cool" one, but wasn't really in the mood to pose, so it resulted in "femail Grinch"

Inesa,

We adjust the temperature of the water at 60 degrees celcius. This temperature in combination with the high pressure is sufficient in order to remove the dirt from the trays. But most of these high pressure machines can produce even steam (eventually useful for other cleaning applications).
The employee is using a normal rain coat and boots.

Ozone tray washers if your plant is plumbed for ozinated water is a thought.

Bill Nelson out of Seattle, WA designed one I hear for the Alaskan seafood industry.
