Raw milk, vegetable oils and other liquid ingredients such as whey-based products are stored and are gently and hygienically handled on being received into the plant. Ahead of further formulation, raw milk typically undergoes cream separation with optional subsequent standardization. Besides the continuous control of the standardized milk fat content, the automatic standardization units can also provide a continuous control of the cream fat content and a proportional dosing of additives.

Pasteurizier for milk powder

GEA provides a range of technologies to reduce or remove bacteria and spores from liquid ingredients, ensuring sensitive products remain undamaged and the highest levels of microbiological safety are achieved. Pasteurization as traditional heat treatment reduces bacteria and spores, whereas bacteria removal separators and microfiltration remove them.

GEA HYGiTip

The HYGiTip is a core element in our complete bag handling and emptying solution. When configured with de-palletizing/outer stripping, sterilization, powder handling, dust collection and waste management, plant operators are able to let this automated solution run continuously with minimal supervision, increasing OEE and enabling personnel to concentrate on other value-added tasks. A typical plant solution may include: de-palletizing, outer bag removal, UV sterilization, automatic bag emptying, powder handling and waste removal.

GEA INLINE FORMULA® SOL High Shear Mixer

The addition of Lactose is typically achieved via a standard funnel mixer, following which the product is passed through a holding tube to ensure it is fully dissolved. The mix is then regeneratively cooled before being chilled to <8°C and finally sent to storage. To achieve decoupling of lactose tipping and dosing operations, storage tanks are carefully sized. As an alternative, lactose powder can be dissolved directly into the milk at the standardized milk storage tanks. This process is similar to that employed when the powder is dissolved into water or inline using a vacuum mixer.

As an option, the skimmed milk can be pre-concentrated by RO. The degree of concentration depends on the heat treatment required and end-product characteristics, and must therefore be considered on a specific project basis. The process will run cold at 5-8 °C for up to 20 hours between CIP.

Evaporazione per l'industria lattiero-casearia, latte in polvere

Further heat treatment is applied to the formulated product on the evaporator using a number of different solutions to ensure both stability and microbiological safety. Our low thermophile system, UHT technology, direct steam injection and steam infusion technologies are examples thereof. The product is then further concentrated ahead of being dried using a falling-film evaporator.

Omogeneizzatore Ariete 5400

In dairy applications it is common for high pressure homogenizers to be used. This is due to their ability to apply dynamic high-pressure energy to break particles in the fluid down to the smallest, potentially nanometer-scale size. As a result of this high pressure homogenization process, an emulsion is created that is stable when the mix is concentrated, dried, packed and resolubilized by the end customer.

MSD spray dryer

For the final removal of moisture to produce a dried powder, a GEA MSD® Spray Dryer is recommended for milk powder. The resulting spray drying process produces consistent, precisely defined functional powders with uniform bulk density and robust agglomerates and that are readily re-dissolved in water. The MSD® benefits from a new CEE cyclone design, which allows customers to maximize fines recovery while minimizing smearing and energy use. Our fines system requires zero intervention and allows fully automated CIP, reducing the risk of contamination and ensuring less downtime on the dryer.

scan-vibro-vaglio vibrante

Using a GEA Scan-Vibro vibrating screen the dried powder is sifted to remove oversized particles before being gently conveyed to storage using either dense phase conveying or gravity to minimize breakdown of the powder. To minimize interstitial air the powder is drawn under vacuum and is flushed with nitrogen before packing. The result is a powder that has an enhanced shelf life due to its very low residual oxygen content.

GEA Filling RBF-800

For Modified Atmosphere Packing (MAP) into 25kg bags or bulk containers, GEA offer a range of powder filling solutions. To improve overall operational efficiency whilst reducing labor demand, GEA 25kg Limited Intervention (Li) filling machines feature fully automated bag handling. For customers that require a turnkey solution, manual or automated palletizing options are also available for integration.

Refrigeration

GEA in-house experts have extensive experience of integrating smart cooling & heating solutions into the complete milk powder process. Customers benefit from lower energy consumption, minimized operating costs, increased sustainability and reduced carbon footprint, in addition to having full confidence in GEA as a trusted partner.

Automation

To ensure optimum efficiency and performance, GEA technologies can be configured with full automation. For example, the GEA Codex® solution delivers full and transparent traceability of both raw material and ingredients throughout the entire process and into the final product.

Approfondimenti GEA

GEA e Pulmuone rendono onore alla tradizionale produzione artigianale dei noodle freddi

Quando il produttore alimentare sudcoreano Pulmuone, attento alle tematiche ambientali, ha proposto a GEA di sviluppare una versione moderna dei tradizionali noodle freddi (naengmyeon), gli esperti di R&S di GEA si sono dimostrati pronti a cogliere la sfida. Hanno contribuito a sviluppare quello che oggi è un successo commerciale, prodotto con meno acqua ed elettricità rispetto ai metodi precedenti. Il risultato è anche fedele alle origini tradizionali del piatto e ai principi salutistici, di benessere e di sostenibilità di Pulmuone.

Con GEA contro la crisi idrica

Nella battaglia globale per la sicurezza dell'acqua, le soluzioni GEA per il risparmio e il trattamento idrico stanno contribuendo a ridurre l'uso, lo spreco e l'inquinamento di questa risorsa nelle fabbriche, nelle aziende agricole e nelle città di tutto il mondo.

Pre2Fuel: pronti al decollo

L'innovativo processo di GEA segna una svolta fondamentale nel pretrattamento dei biocombustibili, come l'olio vegetale idrotrattato e il carburante sostenibile per l'aviazione. L'eliminazione del processo di sbiancamento offre ai produttori un notevole potenziale di risparmio: oltre il 50% in meno di costi operativi e fino al 12% in meno di emissioni di CO2.
