Résumé

Production of pale barley malt consists from three basic operations: steeping, germination and kilning. During germination the grain undergoes modification. Heat is produced by the respiration during germination of the barley and is removed by cold air with high relative humidity. The optimal temperatures in modern malting during germination are between 14 and 18°C. During grain germination, cooling is provided by the passage of humid air. Air is cooled by water adiabatic evaporation and mostly by refrigeration plant. This solution provides us optimal germination process in relatively hot year period and keeps quality of barley malt. Cooling by refrigeration plant provides malts without high loses of extracts (malting loses) by very intensive respiration and growth. Paper describes the process and results of the refrigeration technology with capacity 1.4 MW of cold corresponding to the malt production 27 000 t per year.
