CIP process flow chart need specification

Dear food process professionals,

Please help me that I need a common or basic specification for my CIP flow chart I have attached here.

Ideally I am looking for the following

a) rinsing temperature,

b) rinsing time,

c) concentration of chemicals.

once I decide specification, my plan is to validate the process in my company

I would be very grateful, if you share your knowledge on this,

thanks and regards,

Salim

Salim,

The 3 items you are questioning unfortunatly vary greatly depending on your type of product and chemicals used.  My best advise would be to work with the company who you purchase your chemicals from and the company who put in your CIP system.  As the possibilities could be endless!  Some of us may be able to start you in a direction if product, chemical, and type of item you are washing are provided.

Also you will not be able to upload attachments to IFSQN untill you have reached a certain number of posts.

Best of luck

Hi G,

Thank you so much your reply. yes, we are installing a new CIP system, So supplier only ask us the CIP chemical and process specification. our product is normal liquid brine and some sauces

here is my CIP flow plan and chemicals

1) Hot water rinse to remove sediments or dirt from the line

2) Base rinsing for removing organic matter from the line (Soda)

3) Intermediate rinse with water to remove the base or acid from the line

4) Acid rinsing for removal of in organic matters by citric or nitric

5) Final rinsing with water to complete draining of acid and base residues from the line   

So as I mentioned before I am looking for normal concentration of soda, citric/nitric acid, temperature of water rinsing and contact time

I will grateful if you share me more information on this

Thanks and regards,

Salim

Based on a "general" personal history and this is only me a non-chemist, non-sanitatarian.

Pre rinse at ambient temp for as long as needed to remove solids (can be used water from any of the chemical rinses of the previous wash)

Soda at 0.6 to 0.8% at about 70 C for anywheare from 15-45 mins (again depends on soda manufacturer and amount of soil to remove, type of vessel you are cleaning; silo, vat, line, pastureizer)

Soda rinse at least 45C till a netral pH

Acid at 0.3 to 0.6% at about 60 C (not much hotter as fumes are hard on people and equipment

rinse at what ever temp you like ~35 C maybe till a netral pH

any sanitizing you may need/want

So you may think of this as a start and work the vendors of your soda and acids to determine what is best for you.  Do not use these parameters just because I said they worked for me

Hi gfdoucette,

Thks yr input.

I have no experience CIP but i would imagine that 1% citric acid has a rather different potency as compared to 1% nitric ?

Dear All,

Thank you all for the sharing. Yes, as you advised, before I go to my line I will go more through that and confirm

Regards,

Salim

Yes Charles it would, hense my recomendation to the actual chemical provider,  as things in Salim's corner of the vast globe may be different than mine.  It also depends on water hardness and other trace minerals in the water supply and potable water or C.O.W. water (Condesate of Whey, any water off an evaporator)?  Plus several other factors
