Temperature profile control in LB Electronic mashing apparatus

Standardized congress mashing procedures defined by MEBAK and EBC protocols require precise thermal ramp management during malt sample conversion.

Congress mashing baths LOCHNER LB Electronic incorporate a digital controller and a submerged platinum Pt100 temperature sensor that directly monitors liquid temperature inside the sample beaker.

Electric heating elements increase the water bath temperature at a rate of one degree Celsius per minute up to seventy degrees. Continuous circulation prevents local thermal stratification around the beaker walls.

Operators follow temperature-time curves on the mobile terminal display and export complete logs via standard interfaces.

Preparation of stainless beakers, agitators and Duran dosing tubes

Accurate determination of malt extract yields depends upon the physical precision and surface finish of laboratory sample containers. Operating beakers for LOCHNER LB mashing units with 4 to 20 positions are manufactured from polished AISI 316 stainless steel alloy.

Before starting an analysis series, empty numbered beakers undergo precision weighing on analytical balances. Flat-blade stirring paddles lock securely into bayonet drive chucks to maintain uniform clearance against vessel walls.

Distilled water addition is conducted through precision calibrated dosing tubes made of heat-resistant Duran borosilicate glass to compensate for evaporation loss.

Forced beer aging protocols in dry air Lochner Force chambers

Predicting shelf life stability of filtered and unfiltered beers requires controlled temperature cycling to accelerate haze formation. The Lochner Force beer aging chamber executes automated temperature alternation between zero and forty or sixty degrees Celsius without requiring a messy water bath.

Conditioning beer bottles in dry air flow preserves paper labels and prevents humidity build-up inside laboratory facilities.

An integrated microprocessor records measurements from a secondary temperature sensor placed directly inside a reference container, delivering verification logs to an external printer terminal.

Optical alignment and phase contrast setup on LOCHNER microscopes

Microbiological control of brewing yeast cultures and packaged beer is routinely conducted using LOCHNER laboratory optical microscopes. The instrument is positioned on a vibration-isolated work table and aligned according to Koehler illumination principles for uniform field brightness.

A specialized 63x plan achromatic objective provides high-contrast visualization of Saccharomyces yeast cell walls without requiring immersion oil. For detecting wild bacterial contaminants, the revolving nosepiece switches to a phase contrast condenser turret.

Dimmable LED illumination maintains stable color temperature during digital imaging.

Calibration of LL-21 digital pH meters and DHS sensor maintenance

Hydrogen ion activity in mash, sweet wort and finished beer represents a decisive parameter for enzymatic conversion and biological stability. LOCHNER LL-21 portable analyzers utilize smart DHS digital sensor technology, storing calibration factors and verification timestamps within the probe chip.

Prior to production monitoring, operators conduct automated three-point calibration using standard buffer solutions while checking electrode slope efficiency. The sealed IP 57 housing protects internal circuitry from liquid splashes.

Glass measuring electrodes are rinsed with deionized water and preserved in liquid storage electrolyte.

Conductivity monitoring in water treatment and cleaning solutions

Electrical conductivity of municipal and brewing liquor determines mineral balance and buffer capacity throughout mashing.

LOCHNER LL-21 and LL-26 conductivity meters feature four-electrode cells with automatic temperature compensation, providing linear measurement response across varied dilution ranges.

During verification of rinse water following automated clean-in-place cycles, the instrument applies a temperature coefficient of two percent per degree Celsius. Storing logged measurement profiles in non-volatile memory ensures traceable data records during internal brewery quality reviews.
