The heating of mash in mash mixer is suggested to be carried out by HEATING WATER, which goes to heating of mash; thus, refusing from heating MASH ITSELF by the steam ejector/M-102 live-steam head. Apart from technological benefit of measure implementation, which is excluding the possibility of partial loss of reducing sugar, which turns into caramel under steam treatment at the temperature above 110…150оС and irretrievably dissolves in the following technological processes, the measure implementation enables to refuse from the constant steam supply to the ejector, in other words - reduce consumption of steam and losses of enzymes inactivated by steam treatment.
In case of refusal from using the steam ejector, it is OBLIGATORY to perform periodical local bacteriological decontamination of the mash mixer. Chloride of lime is used as disinfectant. Bacteriological decontamination is to be performed NO LESS frequently than every other day. The opportunity of water heating for mash by RECUPERATIVE heat exchangers should be pointed out additionally; it enables to rationalize heat energy consumption.
The main point and method of measure implementation has been thoroughly explained while performing the 1st stage of the audit and need no additional explanations or comments
