Foremost Farms Cheese Plant Closure Tightens Block Cheese Supply
Foremost Farms will close its Wisconsin plant by December, ending local 40-pound block cheese production and shifting buyer options.
Block Cheese Production
Processing Standard
Industrial dairy manufacturing converts fluid skimmed or whole milk into uniform solid rectangular forms suited for commercial slicing or bulk rehandling. Standardized block cheese production regulates moisture levels and butterfat ratios to meet federal identity standards for cheddar or mozzarella formulations. Quality control boundaries terminate at the bulk packaging line before aging or conversion into retail consumer portions.
Yield Behavior
Milk solids concentration determines the net mass yield per hundredweight of raw milk processed through coagulation vats. Modern block cheese production relies on automated curd cutters and vacuum sealing systems that minimize trim losses while maintaining block geometry. Moisture retention varies with vat cooking temperature and whey drainage duration.
Fluctuations in raw milk protein content directly alter cheese yields, requiring plant operators to adjust standardization ratios in real time. Advanced membrane filtration technology isolates whey proteins prior to vat entry, maximizing fat and casein recovery. Vat retention times directly dictate hourly plant throughput and influence final block density.
Temperature variations during pressing create density gradients that cause downstream slicing machinery to jam or produce uneven portions.
Storage Requirement
Controlled atmospheric curing environments prevent surface mold formation while preserving interior moisture balance during multi-month aging cycles. Excess moisture trapped within sealed corrugated packaging causes gas formation and package blowing. When temperature controls fail during transit or cold storage, fat separation degrades structural integrity and renders the product unsuitable for high-speed mechanical shredding.
Uncontrolled humidity accelerates mold growth on outer block surfaces.
