QUALITY & EFFICIENCY FOR A DYNAMIC MARKET The milk processing industry is facing significant challenges: Despite constant demand and rising prices, profitability and competitiveness are negatively affected by higher operating costs for feed and energy. In addition, geopolitical developments and climate change are causing unpredictable production conditions, while strict environmental regulations further complicate operations in many regions. In this context, the pressure on the industry to implement more sustainable production methods is becoming increasingly apparent. These methods, in...

Flottweg ensures sustainable, economic processes in milk processing • Conservation of resources: Recovering valuable ingredients from process streams, such as proteins and fats, not only supports the conservation of resources, but also provides an additional source of income. For example, there is a strong demand for whey proteins from cheese production as a basis for meal replacement drinks or food supplements. • Energy savings: Efficient centrifugal separation processes can significantly reduce energy consumption, especially in combination with thermal processes. • Product quality:...

SUCCESS IS … LEVERAGING NEW POTENTIAL Flottweg separators and decanters have proven their worth in a variety of applications, especially in the production of raw materials or processing by-products, such as whey, which is one of the greatest sources of high-quality protein. Processing by-products also offers opportunities for the financially lucrative recovery of proteins, fats, or product water. Flottweg separators and decanters are specially developed for the industrial processing of dairy products. These industrial centrifuges are easy to operate and are characterized by their high...

RECOVERING RECOVERING VALUVALUABLE ABLE INGREDIENTS INGREDIENTS FROM FROM WHEY WHEY During cheese production, the largest amount of processed milk by far remains behind as whey. But this whey is more than just a by-product as it contains valuable ingredients, including: ∙ ∙ ∙ lactose whey protein minerals The modern dairy industry processes the whey into valuable products – these range from whey drinks and baby food to additives for pharmaceuticals. Any remaining residue, such as broken cheese particles (cheese fines) and residual milk fat, can be separated and recovered from the pure whey...

ALCOHOL ALCOHOL EXTRACTION EXTRACTION FROM FROM WHEY WHEY Another way to create an additional valuable product is to make alcohol from excess cheese whey. The “whey beer” contains a high proportion of fine yeast cells. It is therefore advisable to separate the yeasts from the mash using a Sedicanter® before distillation. This prevents fouling processes in the distillation column, increases the column’s operating life, and reduces the consumption of energy and CIP media. The permeate produced by the ultrafiltration of whey still has a significant lactose content. Instead of throwing this...

CASEIN CASEIN RECOVERY RECOVERY To recover casein, the skimmed milk is acidified to its isoelectric point. This can be done using both biological and mineral acids. Alternatively, casein is obtained by enzymatic precipitation (enzymes such as chymosin and rennet). Acidification neutralizes the negatively charged casein micelles, resulting in precipitation of the casein. In a similar way to the rennet precipitation process, the casein is separated from the whey, followed by several washing stages in a decanter. Cheese fines are once again removed from both the whey and wash water via the...

EXTRACTION EXTRACTION OF OF CALCIUM CALCIUM PHOSPHATE PHOSPHATE Calcium phosphate, also called milk salt, is a major part of the minerals contained in milk. The extraction of calcium phosphate (DCP process) from whey has become increasingly important in recent years. This is for two reasons: Demineralization not only increases lactose purity but also prevents the formation of deposits downstream. This extends the service life and reduces the CIP cycles. In addition, calcium phosphate is a valuable food supplement that has a wide range of applications in the beverage industry. Calcium...
