A question about dehyderating. 1

[Sunny789]

Can someone please tell me the industrial and non industrial methods of dehydration, I mean, I want to know any new methods rather than the usual sun drying/oven heating or dehydrators, I mean, I need a different method, thank you.

Freeze drying...not new, but another method.

 

[Pud]

Vacuum.
Dessicated (dry) air.

Did you try to Google for an answer?

But the usual industrial method is an oven. A big oven, but an oven, none the less.

 

[Sunny789]

Yeah, just found out about freeze drying, looking into it, its nice, and dry air is pretty much hot air.
but thanks thow.

 

[Sunny789]

Oh, didn't see all those replys before, sorry.
And Google gave the normal method and i need another method.
And no, the usual industrial method is not a oven, its sun drying.

 

[MintJulep]

Considering that I used to work for one of the largest manufacturers of industrial drying ovens I might actually know what I'm talking about.

Unless of course you're asking about a specific niche product, that you haven't bothered to identify.

 

[Sunny789]

Oh, my bad, I was talking about oil.
Thought i mentioned it already.
But I need other methods, which do not include directly heating. Sorry thow.

MJ:

I don't think you understand. There must be something newer and better because the OP does not like the current state of the art. The only reason we can't come up with something better is because we are not innovative or knowledgeable enough.

Fuel oil? Corn oil? Olive oil? Baby oil? Mineral oil? Wataco Danish oil? Oil of Olay? Mink oil?

 

[Sunny789]

Coconut Oil.

Drinking a lot of beer the night before works for me.

 

[rb1957]

and what are you doing to the oil ? what is the point to drying it ? why sun drying (which is free) unacceptable ??

 

[Sunny789]

Its unacceptable becasue in that method , it gets dirty and they get infected with bacteria and all, and it takes 5 days, but in a dehydrator, we can decrease the time, and it is safe.

 

[Sunny789]

And to make coconut oil, you have to decrease the moisture content of the coconut to about 6% from 60%, and if you are asking why we have to decrease it, you mite have to ask the guy who made the method like 100 years ago, i guess. ;\

 

[MintJulep]

Spray drying might work. It's usually used to produce a solid (powdered)final product, but off hand I don't see why it wouldn't work for an oil.

Vacuum flash should work.

Depending on the miscibility of water in coconut oil freezing might work. You could, depending on what happens, filter out the ice crystals, skim off the ice or decant the oil.

 

[Sunny789]

I did think about Spray drying, but what is vaccum flash?
And I was just looking into freezing method, loooots of people toled freezing method.
I looked up even supercritical CO2, and do you think Calcium Hydroxide would work?

 

[Compositepro]

It is unlikely that he is sun drying oil. The OP is probably sun drying the coconut meat to make copra.

This article says that the other method is to use a centrifuge to separate the oils from the liquid extracted from undried coconuts.

 

[Sunny789]

Oh yeah, my bad,should have read wiki, but then industrially they use the other method, the method he used didnt get any proper smell or feeling, so industrially they used the other method.
