Calcium lactate is come from

Lot of lactic acid iron, Calcium lactate come from , after years of research findings : First, wine chronically high water hardness , especially calcium and magnesium ions is high, coupled with excessive acidity of fermented grains for many years , resulting in generating pit wall a lot of calcium lactate . The second is in the brewing operation, for many years a large number of continuous use dry iron beds, shovels , Jan drying machine, large iron grab . Especially in the northwest region , in order to reduce labor intensity , the widespread use of iron hanging large bed ; workers to operate all use shovels ; dug pits and pit entry grab all use iron . This results in every three to four years to be replaced once a dry bed ( dry bed of the original thickness 1 cm , consume too much thinning due to the use and must be replaced ) . Less than a year , each operator to replace a shovel ( with dry bed replacement of the same nature ) , which consume most of the iron is undoubtedly the acid with fermented grains and gradually integrate into the pit buffered lactic acid , and then in the pit wall gradually generate a lot of lactic acid iron , resulting in the wine business for a long time with very little artificial old cellar . Plus the usual support poor pit , pit mud 2 to 3 years to aging and must be replaced with new mud pit .
