Re: Co2 For CA Cold Store
I mean by cooling the co2 by ammonia and pumped it to the CA chambers.

Re: Co2 For CA Cold Store
We had done similar work with Kwality ice creams long back. Co2 handling is very very tough & unless one follows precautions things could be dangerous. TWO issues. Toxic levels & pr built up in the cold store. At present , I do not believe India is really geared up for such things

It's impossible to make anything foolproof because fools are so ingenious...
Don't ever underestimate the power of stupid people when they are in large groups.
Please, don't teach me how to be stupid....
No job is as important as to jeopardize the safety of you or those that you work with.

Re: Co2 For CA Cold Store
We had an enquiry on similar subject. The idea is that say for Banana Ripening chambers you retard the rate of ripening by introducing Co2 in the room. & incedently the Bananas were to be exported to Europe & ripening process was to be completed in that country. The concept was to minimise the damage of ripened fruit during transport. Few companies here were hooked on to this idea first. Infact those were fertilisers companies & they had Co2 as their by product. We worked with them for a long But eventually nothing came out. Though on paper the idea was excellent. They also tried few R& D efforts to find out the duration with Co2 etc in the cold store for various fruit wherein the ripening process gets retarded.

Re: Co2 For CA Cold Store
A while ago I worked on banana carrier. As far as remember, the technology to transport bananas was following:
1. After loading, temperature should be pulled down as fast as possible to 13.3 degC.
2. Temperature should be kept as close as possible to 13.3 degC. Acceptable fluctuation is from 13.1 degC to 13.5 degC.
3. Refrigerated spaces should have limited ventilation to keep Co2 level below 0.1%.

Re: Co2 For CA Cold Store
Hey guys, we are getting off track on the subject.
The poster is looking for information on using CO2 as a secondary refrigerant (similar to using a brine/glycol solution) and pumping it to the coils.
At least I think this is what he is looking for.If all else fails, ask for help.
