The working principle of Brew Kettle with External Calandria
The external calandria normally is made up of tube type or plate type calandria to heat by circulation, which install outside of kettle tank independently. When the kettle tank is working, the wort with 2.5 m/s speed flow through calandria from bottom to up or few times turn back by parallel tube. To speed up wort circulation, one wort pump is necessary between wort outlet of kettle tank and calandria. The pump flow capacity need to confirm with 8-12 circulation times per hour. The wort after heated by calandria flow through kettle tank in tangent way or transfer wort into wort catheter with umbrella cover by middle line. The wort boil temperature will adjust by control inlet valve, normally the external boil wort temperature is 107℃-110℃。
The uniform level for wort boil also can not ignore when use external boiling system. The experiment prove, the wort pressed into kettle tank have best uniform level from reducer tube or tangent way.
The external calandria can match use with 2-3 kettle tank, in this situation, the kettle tank use as temporary tank, hot wort tank, or whirlpool sediment tank and avoid oxygen ingestion from outside.
To reduce energy loss, external calandria and kettle tank should configure insulation. The external calandria which heated by steam, the steam pressure is better not over 0.4 MPa to avoid wort color level increase much. It is not good to external heating system and other traditional boiling system if heating surface overheat.
