Abstract
The many processes used in a brewery, e.g., boiling, CIP, and bottle washing,
are intense energy consumers. With the current continuous increase in energy
prices, it is increasingly important for companies to become free from this
unpredictable variable. Krones AG has developed a concept that uses solar
thermal energy in the brewery to support traditional energy sources. With the
use of a solar collector (with water as the heat transfer medium), the vision is
coming closer to reality. As an example, nearly 90% of the fossil fuel energy
requirement of a bottle washer can be fulfilled by solar thermal energy during
the summer in Germany. The overall economic benefit depends on the location of
the brewery and the amount of solar energy reaching it. But, if it is possible
in Germany it must be possible almost anywhere in the world.
Keywords: brewery heat requirements, climate protection, hot water
preparation, regenerative energies, solar heating, vacuum tube collectors
S�ntesis
Muchos de los procesos cerveceros (hervor, CIP, lavado de botellas, entre
otros) son fuertes consumidores de energ�a. Los constantes aumentos de precio de
la energ�a hacen imprescindible que las empresas se liberen de este variable
impredecible. Krones AG ha desarrollado un concepto para la utilizaci�n de
energ�a t�rmica solar en la cervecer�a como refuerzo a las fuentes tradicionales
de energ�a. Con el uso de un colector solar (usando agua como el medio de
transferencia de calor), la visi�n futur�stica se est� convirtiendo en realidad.
Casi 90 por ciento del requerimiento de energ�a (normalmente suplida por
combustibles f�siles) de una lavadora de botellas puede ser satisfecho por
energ�a t�rmica solar durante el verano en Alemania. La rentabilidad global
depende de donde est� situado la cervecer�a, y de cuanta energ�a solar se
dispone en ese lugar. Si es posible en Alemania, deber�a ser posible en
cualquier lugar del mundo.
