Adding Water to Hit Gravity Target | Community | …

 · Thanks for the advice everyone, it seems as though there''s really no issue with adding water. It''s funny, when I started brewing I did several extract batches, but I guess I never felt the need to adjust the gravity by adding water (or maybe I did and I''ve forgotten). #10 minderbender, Apr 25, 2017.

How to Size a Thickener

2016-3-8 · At 3:1 dilution R = 0.30 feet per hour At 2:1 dilution R = 0.15 feet per hour Final Density D = 1:1. Applying this data to above formula, you obtain: A = 1.33 (4 – 1)/0.50 = 7.98. A = 1.33 (3 – 1)/0.30 = 8.86. A = 1.33 (2 – 1)/0.15 = 8.87. Factor of Safety: Normally a 25 per cent factor of safety is allowed in determining the thickener ...

A GUIDE TO UNDERSTANDING AND MIXING THICKENERS

2020-4-3 · mechanically, the system is subject to high shear mixing conditions. Simply adding powders on top of an agitated batch used to be the only way to introduce thickeners. However, most thickeners, due to their hydrophobic groups, resist wet-out upon contact with water and could float on the surface for hours. Mixing operators are then forced to

Liquid soap diluting, thickening | Soapy Stuff

If the oleic acid content is a lot higher than 50%, the soap might be pourable for a short while after dilution, but it is likely to revert back to a non-pourable jelly, even after adding a lot of water. Avoid this problem by reformulating the recipe to lower the oleic acid to about 50%. A olive oil (castile type) liquid soap is an example
