Dinnissen Process Technology from the Netherlands introduces our latest innovation for the food industry. Our desire for constant innovation has recently led to the introduction of an improved D-Topline Process Unit, a model based on the familiar Pegasus double-axle paddle mixer.

The shape of the D-Topline installation is modified to create in a drop shape, reducing the risk of product adhesion. With this machine we can spray on, mix and cool the product via a thermplate cooling jacket, which ensures that the products stay below the critical temperatures during processing.
In addition, this D-Topline Process Unit is equipped with an additional hinged jacketed front door. This feature makes it easier to inspect and clean the mixer. Our latest design is completely C.I.P.- cleanable and equipped with split-seal Tri-Clamp connections.

Dinnissen Process Technology’s new DIMAX 200 bag emptier remains effective under extremely difficult conditions

Dinnissen Process Technology has developed a new Extra Robust bag emptier that continues to function effectively even under the most extreme and difficult conditions. The bag emptier is a new version of Dinnissen’s classic Dima 200 and was specially developed to handle bags of up to 75 kg of varying size and material. It also has an increased throughput capacity and is more versatile.

Fully automatic bag emptier for use under very extreme conditions

Installations used for emptying bags often encounter problems if they are subjected to extreme loads for longer periods of time. As companies need to continue operating efficiently and without problems even under such conditions, Dinnissen has developed a new DIMAX 200 bag emptier that can continue to handle 75 kg bags of varying sizes and materials quickly and efficiently. All the components of the new DIMAX 200 that have to withstand extreme loads are built to extreme specifications, including the feed-in platform that can handle an increased throughput of even heavier bags. The feed-in opening with a vertical clearance of 26 cm is also larger than in the classic version of the Dima 200, allowing for the problem-free input of extra-large bags. In the new model, the pivot point, arms, and pressure boosters have all been further upgraded and strengthened to ensure a better grip on the bags. The cylinders, dampers, drive mechanism, and bearings are also built to withstand heavier loads. As a result, the extra robust DIMAX 200 is much more powerful and can continue to operate problem-free and without any extra maintenance being required even under the most extreme and difficult conditions.

Contamination-free design and optimum accessibility for maintenance

Dinnissen’s new DIMAX 200 bag emptier also features improved access to the knife for cutting open the bags, so that the knives can be replaced more quickly and safely. The inside is finished with a special Viwateq® Finishing coating that is extremely smooth and easy to clean. In combination with Dinnissen’s fully automated cleaning-in-place concept based on airflow and suction, this ensures that the DIMAX 200 can be cleaned easily and effectively and prevents contamination. An ultrafine version of the bag emptier is also available especially for situations in which it is essential to prevent the release of even the smallest quantity of particles during the emptying process. This version comes with a double filter with powerful suction and a special dust-tight seal for the air exhaust, thereby ensuring that the quantity of particles released is minimized to less than 0.1 mg per m³ of material processed or less than one part per 10 billion.

More information

Depending upon the specific situation, the new DIMAX 200 can handle between 1 and 200 bags per hour and is suitable for use within the feed, food, chemicals, and pharma sectors. More information about the robust DIMAX 200 is available via www.dinnissen.nl.

Sieving – Maximum control for optimal results

Companies in the food, feed, pet food, pharma and chemical industries are being confronted with increasingly stringent requirements with regards to food safety, quality, tracking & tracing, and hazards associated with dust and explosions. Dinnissen Process Technology is continually searching for the best solutions when it comes to quickly and reliably managing various granulated as well as powdered materials.

Efficient fractionation ensures the highest purity

Our sieving technique is based on the use of our centrifugal sieves. The material to be fractionated is brought into the sieving chamber, where the material is agitated by spinning fins. Those fractions which consist of small enough particles pass through the centrifugal sieve, whereas contaminants and larger particles are quickly transported onwards. We can achieve a range of sieve results, by adjusting the diameter of the openings and the residence time of the product in the sieve basket.

XS4 Sifting, high capacity powder monitoring to integrate in transport systems

Regardless of whether powders arrive from silos, bulk transporters or an unloading station, speed of operation and high capacity are almost always essential. Dinnissen’s XS4 Sifting is a method for high capacity powder control that can be integrated with practically any new or existing (pneumatic) transport system. The basis of XS4 Sifting is a centrifugal sieve. A specially fitted feeding system is used to introduce material to the sieving chamber.

Screen protector minimizes loss due to equipment damage and downtime

Metal particles, stones and excessive loading of the sieve elements can damage your expensive equipment. That is why our method ensures that the material to be sieved is distributed over the sieve basket as uniformly as possible. This reduces repairs, maintenance and expensive production downtime to an absolute minimum. The use of a preliminary sieve or screen protector prevents sharp and/or heavy objects from coming into contact with the most delicate elements of the sieving equipment. In addition, the special design ensures that our sieve sleeves are very robust.

International guidelines and strict hygiene standards

We are thoroughly familiar with all the relevant international guidelines and standards – including ISO, ATEX, HACCP, GMP, FDA and EHEDG – so that we can quickly and effectively ensure compliance with all the requirements pertaining to your production process. This is true even for the very strictest hygiene standards, such as those which apply to our customers in the baby food sector. That is also why we supply a wide range of sieving installations in any desired material and finish level – including steel and high-quality stainless steel, with or without an inside layer of wear-resistant or PTFE liner, wear-resistant metal, and electrolytic polishing.

Compact design facilitates integration in new or existing systems

Our sieving installations are available with sieving cylinders in a wide range of sizes – from compact models to extra-long sieving baskets (up to 1500mm) for even more security. We develop customized sieving installations for special situations, which can be delivered quickly and with the added option of choosing which location you wish to use for injecting the product to be processed. Various options are also available for injecting the product including: screw feed, vibration feed, gate feed, or gravity feed. In short, our wide product range and flexible options make it easy to quickly and efficiently integrate our sieving installations into your existing pneumatic transport systems and/or production process.

Sieve guidance system ensures ease-of-use and quick inspection

Time is money, and that certainly applies to frequently recurring work activities such as inspection, cleaning and maintenance. That is why all of our sieving systems can be fitted with a guidance system which makes it possible to remove the basket sieve either manually or fully automatically.

We can manage the entire process

Thanks to over 65 years of experience in process technology, our expertise is not limited to sieving technology alone. We also have a great deal of in-house expertise when it comes to the intake and transport of even the most difficult powders as well as accurately weighing, dosing, grinding, mixing and packaging a wide range of materials. We design and develop our own technology and have extensive in-house manufacturing and service facilities.

Sample Carousel enhances the Sampling Systems from Dinnissen

Tracking and tracing, combined with product quality, is of the essence in the modern industry. Dinnissen Process Technology designed a solution for customers who need to be 100% sure about their production quality and maintain the level over longer production runs. To validate this they analyse samples taken after process lines such as drying, mixing, milling and sifting.

The Sample Carousel enables validation per batch or process over a longer time, all connected with the right automation and sample procedure. With this innovation it is quite easy to track & trace a production process. All the client has to do is to select the desired frequency, volume and weight of the samples to be taken. The samples are collected in sampling bags or jars and then quickly secured with a tri-clamp accessory, from which they can also be released quickly and easily. Operator deployment is limited to simply collecting the samples when the process is done.

The system can be integrated into new as well as existing production processes in filling lines, silos, transport systems, and mixing and packaging installations. The sampling system is available in several configurations, giving you the choice to have 8 up to 16 samples to be taken automatically, with a wide range of 25 g to 1000 g per sample.

As the automated sampling system was developed in line with current EHEDG criteria, it also ensures compliance with the strict requirements that apply in relation to quality and food safety. The housing is made of solid stainless steel without any internal welds or seams. The easy-to-clean design eliminates the risk of contaminating the flow of products or samples.
