Hosokawa Micron Expands Powder Processing Test Centre

Customers benefit from even more innovative solutions and optimal convenience

Over the past two years, powder process technology specialist Hosokawa Micron B.V. has made a substantial investment in its Test Centre in Doetinchem, the Netherlands. Berthram Mak, Manager Sales & Marketing at Hosokawa Micron B.V., explains how the latest changes to the test centre have further improved the company’s service to customers in terms of greater convenience, more certainty and lower costs.

Hosokawa Micron B.V. is an expert in mixing, drying and agglomeration technologies (both batch processing and continuous processing) within the global Hosokawa Group. Based on many decades of practical expertise gained in the field, the Hosokawa Micron team of process technologists support and advise customers with regard to the design, construction, installation, commissioning and preventive maintenance of powder processing equipment. This support often involves small-scale trials at the Hosokawa Micron Test Centre to ensure operational reliability, optimal efficiency and long-term customer satisfaction.

Real-life trials

The test centre is a hub for innovation with both existing and prospective clients. “People approach us with a product idea or problem, but they are not sure what is feasible in practice,” says Berthram Mak, Manager Sales & Marketing at Hosokawa Micron B.V. “Some customers don’t have an R&D or test department of their own, while others want to experiment without interrupting their current production activities. They come to our test centre to try out their new products or formulations on a small scale without the inconvenience and cost of downtime at their own factories.”

The test centre enables all kinds of customers to benefit from Hosokawa’s technical insights and advice throughout the product development phase, without having to invest in the equipment themselves. “We conduct real-life trials with various types and combinations of powder processing methods and technologies, as the basis for designing the optimal bespoke set-up to solve the customer’s problem. So our customers have certainty regarding how the end product will turn out in their day-to-day operation, which substantially reduces the risks for them,” he continues.

All under one roof

Hosokawa Micron’s equipment is widely used in many business sectors, including food, pharma, cosmetics, chemicals and minerals/metals, so the company can draw on very broad experience of countless product/powder processing technology combinations when tackling customer problems. The test centre in Doetinchem comprises more than 2,000m² and is fitted with 30 machines. “The combination of its size and its diversity makes our test centre unique in Europe, and it’s one of only a handful of its kind in the whole world. So there’s a pretty big likelihood that we’ll find a solution to most problems!” says Mak with a smile. “Our customers are surprised and very excited when they come to our test centre. They get so enthusiastic when they see how many different types and sizes of machines and technologies we offer all under one roof!”

Controlled environment

Hosokawa Micron’s recent investments in improving the test centre are certain to further fuel that enthusiasm. One key enhancement is the 3.5m-high platform which provides access to two batch mixing test machines and a new filter installation for the continuous drying system below. The new platform is part of the overall redesign of the test area to improve convenience and accessibility. Another new addition is the 50m² controlled-environment room that has been incorporated into the building. “This enables customers to use our facilities and equipment while also working in the privacy of a completely separate room. In terms of layout, the test centre is now better fit for purpose,” explains Mak.

Higher efficiency

The continuous drying system itself has also been upgraded to offer customers higher energy efficiency and ultimately lower costs: “The dryer now has 20% more installed indirect heating capacity, the maximum inlet temperature has been increased from 350 ⁰C to 450 ⁰C and the filter is 65% larger, so the same machine can dry more product,” he adds. Furthermore, the complete drying system has a higher gas tightness level to secure lower oxygen levels, so products with a higher risk of explosion can be processed safely.

Other improvements at the test centre include the installation of a new 800-litre freeze drying system, a new multi-process batch mixer/dryer test unit for the high-temperature treatment of products such as metal powder mixtures and polymers, a new multi-liquid dosing system and a regulable air treatment system. There is also a new, large fluid bed dryer for the continuous agglomeration system which allows an even better simulation of the process in a production set-up.

Contract manufacturing

The test centre facilities can also be used for contract manufacturing. “As the pace of innovation continues to accelerate, we’re noticing a growing interest in our tolling services to help customers get their products to market more quickly,” explains Mak. “Thanks to the recent investments in our test centre, in terms of both installing new equipment and designing new combinations of various process steps, we are now able to provide bespoke multi-process systems – whether for purchase, rental or as a contract manufacturing service,” he concludes.



The facilities at the Hosokawa Micron Test Centre include:

•           Batch mixing: Nauta® mixer, Cyclomix, Vitomix, Conical Paddle Mixer (CPM),
from 1 up to 6,000 litres

How Hosokawa’s solutions can support the insect processing trend

In the face of rising pressure on the planet’s natural resources, the world is looking for more sustainable ways to guarantee a long-term food supply for the growing population. Insects have long been acknowledged as a rich source of protein, and they place a much smaller burden on the environment compared to animals that are traditionally farmed for meat. It is therefore no coincidence that process technology expert Hosokawa Micron is seeing a growing demand for insect-processing equipment.

Ashwin Jagmohan, Application Engineer Food at Hosokawa Micron, has noticed rising interest in the company’s mixing and drying equipment for insect-based applications. “A growing proportion of the food and feed-related enquiries we receive are for the processing of insects such as black soldier fly larvae, mealworms and crickets,” he says. “Another interesting area is the drying and milling of waste streams such as fish heads because of a more cradle-to-cradle mindset. At Hosokawa, we’re in an ideal position to help those customers if they require powder technology. Our Drymeister (DMR-H) flash dryer is widely used all over the world to turn products such as corn fibres, wheat gluten, starch, shrimps, krill and so on into a high-value protein powder – and it’s perfectly capable of doing the same with insects and by-products.”

Drying, milling and classifying in one

The Drymeister combines drying, milling and classifying in one efficient and continuous process step. The material is fed into the grinding and drying section of the dryer’s main body. The Drymeister can cope with various kinds of wet feed material, from slurries and pastes to whole insects. The grinding rotor disperses the wet material into fine particles, which are fluidised in the grinding chamber by hot, temperature-controlled gas. The system is kept under a slightly negative pressure by the exhaust fan, and the surface area of the product is increased so that the moisture is evaporated instantaneously. The gas stream conveys the particles to the top section of the dryer where a classifying wheel selects the particles by size. Then the particles are conveyed with the exhaust air to a powder-air separating system such as a cyclone and pulse-air filter.

Overcoming the challenges

Insects can be difficult to handle when wet because of poor flow characteristics and cohesive tendency, plus they are temperature sensitive. The DMR-H overcomes these challenges easily, however. “The Drymeister has been engineered to dry highly moisturised material in a matter of seconds without damaging the delicate proteins. The system runs at a high air inlet temperature of up to 300 ⁰C, but actually heats the solids to no more than 90 ⁰C; the energy is focused on evaporating the water, so the nutrients and other properties are retained,” states Ashwin. The Drymeister also offers impressive flexibility: “There are lots of different process parameter settings that can be adapted to achieve the optimal particle size and moisture content – from the speed of the mill disc and the classifying wheel to the feed rate, the air temperature and the air flow. If desired, we can produce a fine powder with as little as 0.5% moisture in the end product.”

Energy efficiency

“Thermal drying processes use lots of energy. Our Drymeister is already very energy-efficient, but we’re continuously calculating for maximum energy reduction for each industrial system we offer,” continues the application engineer. “For example, with our economising step we’re able to preheat inlet air with exhaust air in a closed-loop configuration. Besides that, effective insulation materials allow us to achieve considerable energy recovery.”

Another benefit of the Drymeister is its small footprint – it is around 75% smaller than ring dryers or spray dryers. Furthermore, the Drymeister offers good accessibility for cleaning, inspection or maintenance purposes.


Insect farmers have to meet certain quality criteria with their products. But the quality of insect harvests can fluctuate due to seasonal influences, for example, which means that each harvest can have a different size, nutritional quality and so on. “Therefore, insect farmers can use our batch mixing technology to mix several batches of insects to achieve a consistent overall quality level,” says Ashwin. “Moreover, all our conical paddle mixers (CPM) and Nauta® mixers can be executed with a liquid injection system. This can be used for adding flavourings, colourings or oils during the mixing process. So we can support powder/powder and powder/liquid mixing in line with whatever type of insect-based product is needed for further processing.”

In-house testing

All potential insect-based applications are extensively tested at Hosokawa’s in-house test centre, which is unique in Europe in terms of its size and diversity. “To provide the necessary performance guarantees, we test all insect-based applications on our smallest Drymeister – the DMR-1 – to make sure that everything works in practice,” Ashwin adds. “We always run the tests in close collaboration with the customer. During testing, we keep adjusting the various parameters until we arrive at a set point that gives us a stable run: a smooth process with a reliable constant input and output flow, minimal energy use and a uniform end product. We share the results of the various test runs with the customer in a test report. We also show what happens in terms of fineness and moisture content when we push a product beyond the set point and take it to the max. Even if it’s not relevant for that particular project, it can trigger innovative ideas for future applications.”

Future outlook

“We’ve seen a sharp increase in the number of enquiries this year,” he continues. “Various successful trials have been conducted and there are strong signs that many of our machines will be up and running in real-life production environments before long. Insects have been eaten in other cultures for generations, and insects as part of the Western diet as a sustainable protein source – whether they are eaten in whole or in processed form – could be a step in the right direction. It’s great to see signs that this trend is finally taking off, and even more exciting that Hosokawa Micron can provide processing equipment that is such a good fit,” he concludes.

Heat treatment puts ‘clean label’ within reach

An ever-growing number of consumers are opting for food products that do not contain E numbers – additives used by the processing industry to produce food with the desired characteristics. With the CPD dryer/mixer, Hosokawa Micron is introducing a reactor that can give powdered food products the desired characteristics through a special heat treatment, eliminating the need for additives.

All additives that are permissible in Europe as E numbers have been thoroughly tested before being allowed onto the market. One such E number is oxygen, so it is difficult to avoid E numbers altogether...! Nevertheless, there is a clear trend among consumers towards ‘clean label’ products, i.e. food that does not contain E numbers. When consumers can choose between two products of equal quality, one of which contains E numbers and the other which does not, they have a clear preference for the one without.

“If they want to avoid or reduce the addition of E numbers, manufacturers have to alter the characteristics of their ingredients in order to achieve the intended finished product,” says Daan Goris, Team Manager Food at Hosokawa Micron in Doetinchem. “This can include things like swelling, viscosity, colour, flavour, shelf life and all kinds of other aspects. Additives are one way a manufacturer can create a reaction in a product, but a thermal process combined with pressure or a vacuum can work just as well in many cases. It’s the same result, just a different approach.”

One disadvantage is that a thermal process consumes more energy than the use of additives. Goris: “But the CPD uses less energy than many conventional technologies, plus the process can be controlled relatively easily and very effectively. Even though things can get fairly ‘lively’ in a process involving a vacuum, high pressure and steam, the CPD reactor is designed to be very robust and there are minimal maintenance risks. Therefore, when it’s time to invest in new equipment, many customers are now opting for a solution that enables them to make ‘clean label’ products.”

Conical Paddle Dryer

Such a process revolves around selecting the right combination of finely tuned processing parameters such as temperature, pressure, mixing speed, mixing time, oxygen level and humidity. Goris: “It’s very important to have the correct settings, because any deviations will affect the product quality. Once you’ve found the optimum settings, you can treat and process a whole range of different powders in the reactor in various phases.” Goris is not willing to name any specific products or applications because that would make it too easy to identify some of the manufacturers and suppliers that have collaborated with Hosokawa on this development.

Hosokawa Micron’s newest reactor is the Conical Paddle Dryer (CPD). As the name implies, this is a dryer with a conically shaped base and central paddle rotor. The rotor blades are geometrically designed to mix/heat the product as quickly as possible after steam has been injected under high pressure for the heat treatment. Goris: “We build each CPD in line with customer specifications. The reactor volume can be just five litres or as much as 20,000 litres, and the pressure and temperature ranges are very broad too. Our maximum used to be 150 degrees as standard, but we recently raised that level even further. With pressures of up to 6 Bar and temperatures of up to 300 degrees Celsius, we now cover every conceivable kind of process.”

The Conical Paddle Dryer can be used for a wide variety of batch processes. “It’s easy to change a huge number of processing parameters. Most customers use the CPD for various products. They sometimes even run successive batches of the same product with different formulations.”

Try before you buy

“If manufacturers think that heat treatment could be a good solution for their product, they can bring a batch of that product to our test centre in the Netherlands. Our motto is ‘try before you buy’. It’s very important that you can find out in advance which scale and processing parameters are needed to achieve the desired product quality.”
