Section 71(c) in The Punjab Distillery Rules, 1932
(c)In certain distilleries, gur or molasses wash, prepared in dissolving vat is run into a fermentation vat after the necessary quantity of bub has already been introduced in the fermentation vat. In such cases the specific gravity of the wash in dissolving vat immediately before transference to the fermentation vat, should be treated as the initial specific gravity of the wash. Where the contents of two or more dissolving vats are transferred to the fermentation vat, the initial specific gravity of the wash will be the mean of the specific gravities of the wash in the several dissolving vats used, calculated where necessary according to example II on page 114 of the Technical Excise Manual. It would be an advantage to maintain a fixed specific gravity in the dissolving vats.
