Milk and Whey

From process expertise and commercial advisory to all the equipment necessary for a complete milk or whey powder production process, we help minimise energy consumption without compromising product safety and quality.

Build a business case for milk and whey powders

Milk and whey powders are important nutritional food ingredients that can be used in many different applications. The powders can be refined for use in many different food applications by separating the proteins, fats, minerals and hydrocarbons. In addition, the powder form is convenient for transporting to regions where milk is not commonly produced. 

Whey powdercan consist of different fractions, depending on the cheese from which the whey is sourced. Typical types of whey powder are sweet whey and demineralized whey, but derivatives such as whey proteins, lactose and permeates are also popular food ingredients products today. 

Choose the best production process

The milk and whey powder manufacturing process must be carried out in a strictly hygienic environment to prevent any bacterial growth in the products. As the chemistry of milk varies significantly, each application and product type must be carefully evaluated to determine the appropriate process 

In terms of required investment and the return on investment, the business case for manufacturing milk or whey powder depends on several factors. These include the availability of the raw milk product and the processes involved to achieve the necessary level of powder quality.  

Commercial and process specialists

Our various specialists can advise you on all aspects of the business case and the manufacturing processWe bring many years of experience in guiding manufacturers to achieve commercially suitable solutionsLooking at each process and business case individuallywe design the optimal process to achieve a satisfactory CAPEX and OPEX – without compromising the safety and quality of the product. 

Our range of equipment and solutions for whey and milk powder includes mixers, membrane filtration, falling film evaporators and spray dryers. 

To meet your production requirements and circumstances – on budget and on time, we provide safe, sustainablehighquality process lines. We design our process lines to deliver on essential commercial parameters, such as quality, energy consumption and production capacity.  

Clean, hygienic milk and whey powder production  

The removal of water to create milk powder prevents the growth of micro-organisms and facilitates the preservation and storage of milk constituents. Spray drying is one of the most convenient techniques for producing milk powders and for stabilising milk constituents. 

Before spray drying, the milk undergoes several processes, including heat treatment, cream separation, mixing, membrane filtration, evaporation and homogenisation.  

Today’s most advanced production know-how and equipment

Manufacturing high-value, high-quality milk or whey powder is a tight-knit operation encompassing several important steps.  

We design the processes and manufacture state-of-the-art equipment for membrane filtration, heat treatment, evaporation, crystallisation and drying. 

A closer look at the processes

Mixing is often necessary for preparing and standardising products prior to evaporation and spray drying.  

Membrane filtration is a unique technology that complements the evaporation and spray-drying of milk products and whey streams. It is applied in various ways in powder processing.  

Ceramic membrane microfiltration (CMF) is useful for reducing the bacteria load in final powders.  

Ultrafiltration (UF) helps manufacturers to achieve accurate concentrate levels of whey or milk protein, whilmicrofiltration removes fat to produce isolates.  

Nanofiltration (NF) concentrates and demineralises whey products before drying. 

Reverse osmosis (RO) is a costefficient way of removing water and producing preconcentrated skim milk and whey streams prior to final evaporation and spray drying.  

SD Prevap® is SiccaDania’s specially developed process combining reverse osmosis and evaporation. It allows you to optimise processes according to your specific requirements, having a positive impact on OPEX and CAPEX.  

Evaporation requires initial heat treatment and pasteurisation step before the milk or whey product is concentrated to approximately 50% solids in a tubular falling film evaporator.  

Spray drying is used to produce either ordinary skim milk powder in a conventional spray dryer or agglomerated milk powder in a three-stage Omega dryer. Instant milk powder can be produced by spraying with lecithination in the last stage of drying.
