Fine-tuning product parameters for instant products

Fast solubility. Low bulk density. Good flowability. Good dosability.

Transform your powders into porous, dust-free, easy-flowing and homogeneous granules by means of Glatt fluid bed spray agglomeration.

Fluid bed spray agglomeration of fine powders enables the production of porous granules with a defined particle specification. Due to the relatively low mechanical forces during agglomeration in the fluid bed, agglomerates with a capillary structure, porous surfaces and only a low dust content are produced. These are the best prerequisites for good wettability. These products therefore have excellent dispersibility and are soluble in water. They have a low bulk density and their particle size distribution – usually between 0.2 and 2.5 mm – can also be controlled. The interconnected powder particles are homogeneously distributed and improve flowability and reduce electrostatic charging.

A wide range of effects can be achieved via the choice of spray medium, its composition and concentration. Simply changing the viscosity of the spray solution influences the internal structure. With a constant formulation, the product properties are thus changed in a targeted manner. In principle, additional additives can also be introduced via the spray liquid during agglomeration in the fluid bed. In this way, for example, the consistency of sauces or the rehydratability of starch can be improved. Raw materials with fatty components, such as chocolate powder, require an emulsifier for better dispersion.

High dosing accuracy, flowability and uniformity are also required for instant products for beverage vending machines. In particular, a defined bulk density for volumetric metering is important here.

At the Glatt Technology Center in Weimar, we work with you to determine the optimum process conditions for your product in feasibility trials for product development. Various laboratory facilities and comprehensive analytical equipment are available for this purpose. On our pilot plants, we optimize the process and scale it up reliably to a stable and economical production scale. The results from this form the basis for the design and construction as well as the erection of your fluid bed or spouted bed plant, tailored to your requirements. As an alternative to our own process technology, we offer you the outsourcing of your production by means of contract manufacturing at Glatt.

Functionalization of particles + bulk material by coating
By determining the quality of the end product, it is essential to select the most suitable technology approach. Individually adjusted coating parameters By determining the quality of the end product, particle coating is a critical step in many manufacturing processes. To achieve optimum results, it is essential to select the most suitable approach and, to do this, the specific properties of the raw materials, the required functionality of the coating and the intended application must all be considered. The most important aspects to think about when coating functionalised particles are outlined below. From the very beginning, those involved in process and product development must define the target parameters, the desired product properties and identify the technological and commercial conditions. Based on these criteria, a suitable technology can then be selected for production. Typically, this is an incremental process that, based on an initial concept, investigates different production variants. The aim is to optimise the process in terms of product properties and costs.

From process development directly to contract manufacturing
With short time-to-market: Particle and functional design from the fluid bed market leader The Glatt Group’s customers benefit from bundled expertise in particle design – from the initial feasibility test, through scale-up, to validation of the production process. Glatt offers suitable solutions for every variant and, if required, also implements customer-specific processes. Contract manufacturing has to fulfill very varied requirements. Some companies permanently outsource their production and permanently request large quantities. Others require flexible production slots to compensate for highly fluctuating requirements in terms of volume. Often, a mature product idea exists, but the innovators do not yet have the suitable technology. For the production and refinement of solid product formulations, a wide variety of tasks are commonplace: from nanodispersed powders for high-tech applications, to matrix-encapsulated feed and food additives in granule and pellet form, to products with a modified release of active ingredients.

How to tame recalcitrant ingredients withtechnological processes
Plant-based functional ingredients behave differently than manufacturers of nutraceuticals and cosmetic products would like. Double microencapsulation can help them to overcome bioavailability and solubility challenges Plant-based functional ingredients behave differently than manufacturers of nutraceuticals and cosmetic products would like. Innovative processes such as double microencapsulation can help them to overcome bioavailability and solubility challenges. Among the currently trending functional ingredients, interest in natural sources such as turmeric and its polyphenol, curcumin, has been increasing for years. The spice is not only in demand in the culinary world, but has also found great promise in both consumer and scientific applications.1 Hewlings and Kalman reported that the reason for this is because of the medicinal properties of this rhizomatous perennial plant (Curcuma longa) from the ginger family, which have been known for thousands of years.2 In Asian countries, turmeric has traditionally been used as a medicinal plant for its antioxidant, anti-inflammatory, antimutagenic, antimicrobial and anticancer properties.3–5 This sought-after ingredient is not only

Drying liquids – Best technology for nutraceuticals
The desired end product properties can make a difference when choosing between spray drying or spray granulation Both spray drying and fluid bed spray granulation can be used to convert liquid products into bulk materials. The most effective process will often be dictated by the desired properties of the final particles and the specific application. Glatt Ingenieurtechnik has a thorough understanding of both techniques and has a long history of designing fluid bed systems that are tailored to individual customer products. Drying solids-laden liquids is frequently used in industry to convert products into a more manageable form and enable their storage at ambient temperatures. The resulting bulk materials are not only more stable than the liquid raw materials, they also have lower weights and smaller volumes, significantly reducing transportation and storage costs as well as any handling issues. To dry liquids as quickly as possible, spraying them into a hot air stream (spray drying) is very effective. It has been used for decades to quickly and cost-efficiently dry large-volume

Spray (micro) encapsulation of sensitive substances in matrix form
An overview of essential oil and vitamin case studies Phytochemicals are increasingly found in many food, chemical and agricultural items. Product and process optimization is becoming ever-more important in all of these industries, with a focus on quality, manufacturing efficiency, stability and formulation costs. Essential oils are volatile substances with a relatively high vapor pressure; they are susceptible to oxidation and light and may change or may even lose their properties when directly exposed to stressors. Like other sensitive, volatile, odor- or taste-intensive liquid active ingredients, they must therefore be protected from the environment or vice versa. For this protection and to simplify handling — as well as for better dosage and targeted release — these substances are therefore progressively offered and used in encapsulated and/or free-flowing forms. Various processes can be used to deliver products with a compact structure. During process development, the most suitable procedures and equipment

Drying and product design in the vacuum fluid bed
Dry, durable, pressure-resistant: Gentle and safe processes for processing extracts containing solvents and temperature-sensitive substances The processing of solvent-containing extracts and temperature-sensitive substances such as microorganisms or enzymes places high demands on process conditions, occupational safety and plant safety. Vacuum fluid bed technology from plant manufacturer Glatt is another way of achieving even more temperature-friendly processes by lowering the boiling point at reduced system pressures. This benefits live cells, products with organic solvents, and also agglomerates with high strength. Aqueous processes and their limits Fluid bed technology is characterized by excellent heat and mass transfer. Each individual product particle is suspended by the process gas to achieve perfect mixing and homogeneous temperature distribution. These well-known advantages of convection drying over contact dryers are utilized for temperature-sensitive products such as yeasts, enzymes and other reactive substances. Efficient drying in the fluid bed enables a variety of other processes such as

Optimising functional ingredients for enhanced nutrition
Fluidised bed and spouted bed processes offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned Fluidised bed and spouted bed processes by Glatt offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned using spray granulation, agglomeration, microencapsulation and coating. The consumer demand for fortified products is constantly growing and has been well received by end users. The form in which health-promoting probiotics, dietary fibres or antioxidants are consumed depends on both the preferences and everyday habits of the individual: some prefer sports drinks, protein bars or enriched iced tea, whereas others favour more direct dosage forms, such as effervescent tablets, sachets or capsules. However, although the manufacturing processes associated with these products present numerous challenges, a universal requirement is that functional ingredients must be stable during storage, precisely dosed, dissolve quickly or have a depot effect.

Spray agglomerating of plant-based milk alternatives
Using fluidized bed spray agglomeration, particle size distribution, particle structure and particle properties can be specifically adjusted and improved. Spray agglomeration of plant-based milk alternatives for perfect wetting and dispersing properties Powdery substances often cause problems during dosing, filling and transport because of their high dust content and poor flowability. Low solubilities and dispersing properties also impair the application of the end product. With the help of fluidised bed spray agglomeration, the size distribution and structure of difficult-to-process particles can be specifically adjusted and improved. According to a study by the Research and Markets Institute, the global market for plant-based milk alternatives will grow at an estimated annual rate of 9.9% until 2025 (vegconomist 2020). Market shares of almond and soy milk are expected to grow particularly rapidly, at 40% and 37% respectively. At the same time, the application and use of powdered products is increasing. Benefits include the fact that less packaging required, which is more sustainable, and transport is both easier
