What's cooking, Josip? Soy? Rapeseeds? Sunflowers perhaps?

Hi Josip,

Terp asks a good question. How is refrigeration used to make edible oil? What type of heat exchangers are used and how low of temperature is required?

Thanks,

Hi, guys

What's cooking, Josip? Soy? Rapeseeds? Sunflowers perhaps?

This is kind of factory secret. I do hope that oil is not coming from GMO seeds I think they use all of them to make a different oil, but mostly of sunflower, at least on the bottle is sunflower picture

Terp asks a good question. How is refrigeration used to make edible oil? What type of heat exchangers are used and how low of temperature is required?

Yeah, sorry I made mistake. That factory produce edible oil, but from that oil they also produce a different kinds of margarine and for that process they need refrigeration plant.

Here are something more about margarine:

Here you can see more or less complete process.

Extrusion machine is pipe in pipe ammonia cooler and depending on amount of added hydrogen before, cooling temperature and time you can produce margarine with diffrent melting points (32-44C or higher) depending on use.

For food we can use only types with melting points from 32C - 36C, otherwise we cannot digest it . To make sweets we use types with higher melting temp due to cooking process under high temperatures around 200C.

Hi Josip,

Thanks for the information. It sounds like scraped surface heat exchangers are being used.

Yes,

inner pipe is actually a pump pipe. Inside is a rotor with some kind of blades for homogenisation of margarine.

There is another name for those machines used by workers in factory but...I do not remeber that (working there before 10-11years )

wouldn't be a Gersternberg and Agger by any chance

We fitted two drums on a Grasso 10 plant, just about the time I started with Cross Refrigeration.

I have two spare secondhand plants from the same customer sitting in our yard at work, both perfectly good, but manual control and not compatabile with modern automated production lines

Kind Regards Andy
