Fish Chilling Unit

03/25/2010 8:09 AM

I have to design the system requirement for the plant having a standard Fish chilling unit and Milk storage unit, so can somebody tell me power consumption for the the standard fish chilling unit and Milk storage unit(Refrigeration system), for the coastal area?

Fish chillers and milk storage units come in a wide range of sizes, so there aren't really any standard heat loads or power consumptions.

A domestic fridge runs about 250-850W, intermittently, depending upon its size.

Put down some parameters, then, in pursuit of providing the information, as indicated in reply #1.

Have you paid your subscription and authorised the transfer of question answering fees to PWSlack's account?*

No?

Then why do you think you can demand (for that is the tone of your posts) any information from other contributors, much less demand detailed output variables without providing any input parameters?

Are you actually an engineer? Do you understand the principles that PWSlack has outlined?

Supply some basic sizing information - e.g. what you consider to be a reasonable internal volume and the temperature at which it should be maintained and the ambient local air temperature - and it will be possible to estimate an answer to your question. Without it, both PWSlack's previous answer and mine below are equally valid.

Power Required: 1.2 MW (suggest installing a Siemens Typhoon turbine gen set).

*sarcasm mode on full for this paragraph**.

**ok, for the whole post...it's been a bad morning

Hmmm..... might be able to shave a bit off that with a reverse-acting Stirling Engine....

Granted, but can you also power the site's lights, aircon and cooking facilities with it? And will it provide enough power to keep the security and search lights on all night and the electric fence powered? And power to the machine gun emplacements?

Can the Stirling Engine also provide motive power for the fish oil and milk pumping stations? And the milk stirring motors?

Honestly, you need to make sure that the full scope is covered! It is also essential to allow for expansion over the first two years of plant operation without having to install upgraded/additional power sources.

Oh dear. Solar would be a better bet, then.

How about a cast iron bath for the heat transfer fluid header tank?

Solar-powered torch, or as it's alternatively called "a mirror" ?

Solar Cold-Light Heat-Pump ?

Give me some time - I'll figure this one, eventually

Will solar provide 24/7/52 power coverage? Is the plant in the artic and therefore would have to rely on battery power for ~5 months of the year?

What area of solar panels is needed? Pay back time?

The genset will, of course, be run on the waste fish oil and sewage gases, rather than mineral oil, so CO2 issues are covered.

Cast iron bath? Is it cracked? Are you cracked? Does it have a lid?

A fish chilling unit in the Arctic? Strewth!

And how do you think the Arctic got to be so cold ?

Ok, more of a thawing unit there...I heard that Inuit use refrigerators to keep their meat from freezing...

<passes monitor wipes>

Argument stands if plant is in the rain forest, under the canopy, where the the sun doesn't reach....

<passes over straws she's been clutching>

Questions: At what point in the journey from arctic to warmer climes would you put the fish into a chiller? If you "over" freeze fish, do they spoil?

To maximise revenues, I was thinking one could add a fertilizer plant to process the dry, degassed sewage and fish processing waste.

......in that case the bio-gas could be used to run that humungous generator....

Never caught a "standard fish"......

Re: Fish Chilling Unit

I apologize for the previous light hearted responses. I'll try to explain what it takes to, "design the system requirement for the plant having a standard Fish chilling unit and Milk storage unit".

Let's assume that a "standard" fish is inflated by the fisherman's imagination and instead of requiring 20 BTUhour per fish to chill, the actual requirement is much lower, due to the exaggeration of the fish hooker.

Milk, on the other hand is usually under weighed by the collector and so, the "Milk storage" requirement is understated by 33.5% per pound of product.

Now, both items are rich in calcium, which has a high thermal conductivity and so the thermal efficiency of the system can be halved if the total load does not exceed the thermal lag of the entire system when fully loaded.

Of course, this all changes with the "coastal area" variable, which can be as high as 2.35, depending on the evelation of the coast and the proximity of the coastal conflasion of the particular latitude indicated.

I hope this helps.

thank you, Sir!!! i can understand but some people need to learn fundamentals of writting a mail.....

i agree that i have not provided the complete information, but i really dont have idea of it so i couldn't able to give the detailed information for designing the system.

" i couldn't able to give the detailed information for designing the system".

If you can't define the system requirements, how can we design it for you?

Good Luck!

PS

As an aside, my fishing grandson used to call a depth finder a "fish looker".

Think about it.

Make sure you have extracted all the hydrogen hydroxide before chilling.
