Hi Guys,

I am currently working for a nutritional company and we are re-constituting milk. We use Compounding Tanks to mix the Oil, Water and Macro Materials (Sucrose, Lactose, NFMS, WPC, etc). The process is really very simple, we just circulate the mixture of oil and water thru a circulation line then add the macro materials in a eductor panel. However, we are currently encountering successive incidences of excessive foam during our compounding process.

These foams hinder us to really empty the tank for pastuerization and homogenization.

Any suggestions on how we can minimize the formation of these foams?


Thanks in advance.

Hi Norman

i never been in company like you but in my opinion, you should check
- at which point the foam started, then
- identify the foaming contributor and;
- try to decrease the rate if let say, a slower agitation can lower the foam formation.
- if let say all the process (temp, pressure, agiation etc) is similar to previous process with no excess foam, you should check the raw material.

i believe by doing some trials will give you the answer

Hope can give you idea.

Norman: I would try to use a high pressure water spray (using suitable water ofcuourse) in order to collapse the foam which is mostly air.

Thanks for the reply guys..

currently, that is what we are doing.. spraying water to collapse the foam... but I would realy like to resolve the issue without adding additional load to the operators.

i'll try the suggestions of fatimah..

thanks again..

Hi Guys,

Which do you think is a better design to minimize foaming?

The one direct to the tank walls, or the one slightly away to the tank walls?

Hi Norman

why you dont just tried at home? put detergent in a pail, direct the water from hose pipe in each way you think less foam produced. See if we can get different result. of course this will be non quantitative result, but hopefully visualization can give the best answer.

it is quite difficult... there are a lot of factors to be considered... the flow rate of the mixture when it touches the walls of the tank, the total solids of the mixtures, and other stuffs.

I was hoping to get some sort of recommendation based on the experiences of others.

Thanks.
