Method for adding hops in beer manufacture

摘要

The invention relates to a method for adding hops in beer manufacture, having the following process steps; a) separation of a sub-quantity (07a) of water and/or wort (07) and/or beer as an aqueous fluid, b) addition of hop extract (10) in liquid or pasty form to the separated aqueous fluid (07a), c) production of a macroemulsion (13) of the hop extract by emulsifying the hop extract (10) in the aqueous fluid (07a), d) increasing the pressure in the macroemulsion (13) of the hop extract to a feed pressure of in particular higher than 100 bar, e) production of a microemulsion (17) of the hop extract by feeding the pressurized macroemulsion (13) through a gap or a valve (16) or by feeding the pressurized macroemulsion against a baffle plate, f) at least partial return of the microemulsion (17) of the hop extract to the beer manufacturing process.

主权项

1. A method for adding hops in beer manufacture, said method comprising:
separating a sub-quantity of aqueous fluid from a quantity of at least one of water, wort or beer; adding hop extract in liquid or pasty form to the sub-quantity of aqueous fluid forming a mixture of aqueous fluid and hop extract; producing a macroemulsion of the hop extract by emulsifying the hop extract in the sub-quantity of aqueous fluid, wherein at least 75% of hop extract droplets in the macroemulsion have a particle size of less than 20 μm; increasing the pressure in the macroemulsion of the hop extract to a feed pressure higher than 100 bar; producing a microemulsion of the hop extract by feeding the pressurized macroemulsion through a gap or a valve or by feeding the pressurized macroemulsion against a baffle plate, wherein at least 75% of hop extract droplets in the microemulsion have a particle size of less than 5 μm; and inserting at least a portion of the microemulsion of the hop extract into the beer manufacturing process.
