Wet type grinding machine for producing mash in beer production

A wet grinder for producing malt liquor in beer production comprises a device influencing the temperature of softened water led in the softening path, for example, when the device is a water mixer (16), an even milling power and an even softening degree for brewing barley can be achieved, thereby achieving a stable milling quality, and by the following control of the water mixer (16) by controlling signals, the temperature of softened water is elevated when the power consumption of the roller driving motor (7) is over high, and the temperature of softened water is reduced when the power consumption of the roller driving motor (7) is over low. When the temperature of the softened water is relatively high, the absorbing capacity of softened water for brewing barley is increased, oppositely, when the temperature of the softened water is relatively low, the absorbing capacity of softened water for brewing barley is reduced, therefore, the utility model is capable of well reacting against barley of different quali
