When combined with a pump, the panel provides maximum product safety. The pump is used to assist the dosing of the yeast or wort. When dosing, the exact measurement is controlled with load cells. An integrated aeration unit allows the yeast to be aerated during the transfer process. Semi-automatic control is achieved using the controls in the brewhouse and via manual valves. This semi-automatic control system can determine the temperature, the quantity of yeast which is dosed and the quantity of wort sampled. Both yeast propagation tanks and the pipes are cleaned using the CIP system.
BrauKon VitaProp® Pro
The fully automatic yeast system VitaProp Pro provides a complete, fully automated process for pure yeast culture, simultaneous yeast propagation, assimilation, dosing and wort removal. Furthermore, simultaneous propagation from several yeast strains is made possible thanks to each propagation tank having its own peripheral equipment. The use of mass flow meters ensures an exact dosage quantity of wort for yeast propagation and of yeast into the wort flow. When doing so, the dosing rate and the flow velocity are calculated, resulting in the most uniform distribution of yeast possible throughout the entire wort cooling period.
During propagation, circulation and aeration cycles can be controlled using two separate input screens. The circulation rate is controlled by the pump velocity and by the opening angle of the control valve and guarantees an optimal distribution of yeast throughout the wort. Thanks to the preservation of yeast cells, high viability (> 98 %) with extremely rapid cell reproduction rates occurs.
Maximum product safety
The yeast tank is intermittently cleaned by the CIP system, just like a fermentation tank. In this process, spraying devices and the circulation pipe are used to fill the yeast tank with cleaning medium. All pipes can be reliably flushed with individually adjustable flow rates thanks to a screw spindle pump which simultaneously serves as the CIP return pump. In addition, all pipes including the product-conducting and CIP pipes can be sterilized due to the use of the combined air-steam pipe. Through the consistent use of leak-safe double-seat valves including dead-space cleaning, cross-contamination is reliably avoided.
