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 between adjoining chambers for assisting and promoting flow in the forward direction and preventing flow in the reverse direction. For example, the agitator may have helical screw sections located in the constricted passages, or the agitating blades may be located proximate the constricted passages, or a one-way valve may be provided at each constricted passage. Heating jackets surround the chambers and preferably have a triangular cross-section which complements the profile of the chambers to provide large heat-exchange surfaces.
