Hard cheeses require high-pressure pressing and prolonged, uniform syneresis to achieve low moisture content, a compact paste, and a firm, closed rind. In Kual molds, two interrelated variables Kual : the grooving—or pattern, design, and depth of the internal grooves—directs the surface drainage of whey and the formation of the rind, while the microperforation—geometry, diameter, and density of the holes—regulates whey drainage while retaining the curd fines. The combination is calibrated according to the rheology of each curd and the pressing program, influencing the coalescence of the curd grains and the formation of the rind. Manufactured from engineering thermoplastic with certified traceability (FDA and Codex Alimentarius): abrasion and impact resistance, dimensional stability, chemical inertness against fermentation acids and CIP solutions, and a non-porous surface with negligible moisture absorption that inhibits biofilm. Available for Parmesano Cheddar, Sbrinz, Sardo, Reggianito, Provolone, Provoleta Romanito.
