Discussion Overview

The discussion centers around the evaporation process of grape juice that contains added carbon, exploring why this juice is harder to evaporate compared to juice without carbon. The inquiry involves technical aspects of the evaporation process and the role of carbon in this context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Trent H notes that the addition of carbon to grape juice makes it harder to evaporate than juice without carbon.
  • NascentOxygen questions the type of carbon being referred to and suggests that clarification on the nature of the juice and the carbon additive is needed.
  • Trent H confirms that the carbon was added to help remove certain compounds from the juice and mentions that more steam is required to evaporate the carbon-containing juice.
  • Another participant inquires about the form of carbon used (e.g., powdered charcoal or chunks of porous carbon) and whether it was allowed to settle or skimmed off before evaporation.
  • Questions are raised about the purpose of evaporating grape juice, including whether it is to create a condensed syrup and what unwanted compounds the carbon is intended to remove.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific reasons for the observed difficulty in evaporating the carbon-containing juice, and multiple questions and clarifications remain unresolved.

Contextual Notes

There are limitations in the discussion regarding the specific properties of the carbon additive and its interaction with the juice during evaporation, as well as the intended outcomes of the evaporation process.

as a process worker may someone with more technical knowledge answer question below please

1. we have a juice which contains some Carbon.I am finding it harder to evaporate due to the Carbon.Why is juice harder to evaporate with Carbon in it then juice without Carbon?

Cheers

If you are able to give more information, someone might be able to suggest a theory. By "juice" I presume you mean the juice of an edible fruit or vegetable? All such juices contain lots of carbon atoms, along with hydrogen and oxygen and others. I can't imagine that you mean contamination with soot particles, so maybe the lack of responses to your query means that other readers are as mystified as I am.

It sounds an intriguing observation, so can you elaborate?

Hi NascentOxygen

Sorry for late responce.Thanks for your reply

Yes the grape juice had Carbon added to the juice to help remove certain compounds.It was harder to evaporate the juice with the added Carbon then juice without the added Carbon.

The juice was send through a Evaporator using Steam as the heating source.More steam was needed to evaporate the Carbon juice then the non-carbon juice

Thanks

Trent
 
Hi trenthoskings. So the carbon was what? Powdered charcoal, or chunks of porous carbon? It was allowed to settle out, was it? Or it came to the surface and was skimmed off?

So we can be sure there was really none of this carbon additive itself in what went to the evaporator?

I'm curious to know why grape juice goes to an evaporator? Is this to make a condensed syrup, or what is the final product?

What unwanted compounds are the carbon removing? Are these compounds recovered for industrial use in another part of the factory?

I'll login and look for your reply in about a month's time? :smile:
