A question about dehyderating.

A question about dehyderating.

A question about dehyderating.

(OP)
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.

RE: A question about dehyderating.

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

RE: A question about dehyderating.

Did you try to Google for an answer?

RE: A question about dehyderating.

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

RE: A question about dehyderating.

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

RE: A question about dehyderating.

(OP)
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.

RE: A question about dehyderating.

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.

RE: A question about dehyderating.

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

RE: A question about dehyderating.

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.

RE: A question about dehyderating.

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

RE: A question about dehyderating.

(OP)
Coconut Oil.  

RE: A question about dehyderating.

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

RE: A question about dehyderating.

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

RE: A question about dehyderating.

(OP)
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. :P

RE: A question about dehyderating.

(OP)
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. ;\

RE: A question about dehyderating.

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.

RE: A question about dehyderating.

(OP)
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. :P
I looked up even supercritical CO2, and do you think Calcium Hydroxide would work?

RE: A question about dehyderating.

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

http://en.wikipedia.org/wiki/Coconut_oil

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

 

RE: A question about dehyderating.

(OP)
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.

RE: A question about dehyderating.

(OP)
And alot of the oil goes wasted in that method, so they ended up using the other method.

RE: A question about dehyderating.

Please use proper nouns.

No one can read through this post and understand what "that method" and "the other method" are.

 

RE: A question about dehyderating.

(OP)
Oh sorry, the method which is usually used is called the dry method, in which they heat the coconut for a day, and then remove the copra from it, then heat it again then squeeze it in a expeller and then take the oil, in the other method, which is called the wet method, in which they use the protein in the  coconut and and make a emultion of the water in the coconut and the oil, because of which you dont get a proper colour and is not very economical. :)
        

 

RE: A question about dehyderating.

how about a clothes dryer ?

RE: A question about dehyderating.

(OP)
Thank you.

RE: A question about dehyderating.

Does the solar method use a collector? That may speed things up.

RE: A question about dehyderating.

Molecular sieve
Or just plain old evaporator.  Circulate it, heat it let it flash.
