Steinecker Pre-masher

    The start for a perfect mashing process

    The blend is the key

    The basis is created during mashing in: for a high wort quality, a high yield and optimal production steps during the brewing process. Intensive mixing of grist and mash water guarantees a lump-free mash, homogenous soaking of the grist particles and fast enzyme activation.

    Thanks to the optimised mixing and flow zone of the Steinecker pre-masher, the finest grist particles come into close contact with the mash water.

    At a glance

    • Dust and lump-free mashing-in up to a mash liquor ratio of 1:2
    • No displacer for easy cleaning
    • Installation either directly on the mash tun or in combination with the mash mixer

    Technical requirements for mashing in

    • The size of the pre-masher is individually calculated based on the mashing-in times and mash liquor ratio.
    • If rinsing and displacement quantities are not taken into consideration, this can lead to incorrect quantities of mash liquor and thus to an incorrect dimensioning.
    • Type-dependent differences in the mash liquor ratio must be compensated by the pre-masher during the mashing-in process.
    • Only an optimised mixing and flow zone will guarantee a homogeneous mashing in.
    • The avoidance of dust and lumps is a prerequisite for safe process conditions and a consistent wort quality.

    This is how intensive mixing of grist and mash water works

    The principle: expansion as the driving force

    • The grist is fed from above and then the mashing water is added horizontally in a side pocket.
    • Swirl vanes at the nozzle outlet of the pocket increase the turbulence in the mixing zone.
    • Reducing the diameter after the pocket increases the flow speed, thus causing the media to expand.
    • This guarantees that the solids are distributed optimally in the liquid medium.
    • These measures force an intimate contact between the finest grist particles and the mashing water.

    Benefits to you

    Ideal blend

    The pre-masher assures a homogeneous blending of the grist particles with the mashing water.

    Optimised transfer of materials

    The soluble substances already contained in the malt are transferred quicker into the liquid phase of the mash. Enzymes diffuse from the grist faster and in a larger quantity, thus providing an increased mash intensity.

    Consistent wort quality

    The avoidance of dust and lumps is a prerequisite for a constant mashing activity and consistent wort quality.

    Use of different grist qualities

    The pre-masher can also be used when processing with hammer mills and raw grain grist.

    Hygienically optimised conditions

    Since this system operates without displacers, there are no blind areas which are difficult to clean.

    Easy installation

    The pre-masher can be installed directly on the mash tun or it can be combined with the mashing-in vessel.
