Abstract
A continuous mashing process for producing wort in the production of beer comprises providing a mash mixture of malt and raw grains; continuously flowing the mash mixture through a mash reactor; and heating the mixture during its flow through the reactor to progressively raise the temperature of the mixture at an almost constant temperature gradient from approximately 30.degree. C at the reactor inlet end to approximately 80.degree. C at the reactor outlet end to thereby form mash. During its flow through the reactor, the mixture is agitated in a controlled manner to effectively prevent overheating thereof and facilitate the extraction and diffusion of the active ingredients in the mixture, and the agitation is carried out so as to prevent back-flow of the mash within the reactor. The mash is then filtered to produce wort. A mash reactor comprises a plurality of chambers connected together in serial flow relationship with one end chamber having an inlet for receiving a mash mixture and the other end chamber having an outlet for discharging the mash. An agitator extends axially through the chambers and is provided with means located in the vicinity of the constricted passages betwee…
