WesFab 7" filter press - how much syrup do you expect to filter per setup?

[Mike Hofer]

Hi,

Looking for your experiences filtering syrup using a full WesFab filter press.

1) Process used
2) Min & max quantity of syrup expected through one filter press setup
3) Factors affecting filtered syrup expectations: Sap PH, Time of season, use of defaomer, etc.

I'm an experienced syrup finisher working with an outfit that does 1500 gallons of syrup finished annually. Our results can sometimes be quite variable in terms of quantity of syrup through the filter press with each setup. Typically, late season sap containing increased niter results in a decrease in syrup filtered with each setup. However, at times we've experienced results that are all over the map. Right now, I'm just looking for your experiences with filtering for comparison. Not sure we have a big problem here, just looking for your experience and knowledge.

One specific question relates to the use of commercial defoamer: if you use a defoamer, how much do you use & when, and do you notice any difference in filter press operation?

Thank you!!

I don't use a commercial defoamer, I use canola oil. My foam issues are usually with the very first batch that goes into the evaporator and after that I have very minimal foaming issues. I normally don't have any issues with the filter press when using it and I don't believe that using defoamer affects the amount of nitre in the sap. That is based on a yearly thing with the trees themselves.
