The Swiss subsidiary of Dutch company DSM Nutritional Products AG makes use of the spray drying methodology when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The procedure uses pump technology to convey various emulsions into a sprig tower, where they’re dried into powder. But the feed and booster pump that was being used proved to be an uncertainty issue because the diaphragm required for the pumping process tended to tear when the pump was began up. Generally, such manufacturing interruptions could be corrected by way of quick upkeep and repair work.
However, it is extremely costly to replace a diaphragm or a complete system. DSM was looking for another and eventually made a discover after they talked to the pump specialists at Lewa Nikkiso Switzerland, who beneficial a Lewa triplex course of diaphragm pump for the spray tower application. The drive unit contains a secure start-up mode that keeps the diaphragm positioned in the impartial place, and continuous regulation using an built-in monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it’s easy to meet the food industry’s stringent hygienic provisions.
a hundred PERCENT INTEGRATION
“Pump expertise plays a central position in drying oil-in-water emulsions for the food and pharmaceutical industries. These emulsions comprise substances such as vitamins, carotenoids, or polyunsaturated fatty acids as active components,” explains Natalie Ibald, plant supervisor of formulations at DSM Nutritional Products AG. “As part of the process chain, each pump is one hundred pc integrated into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With the previous system, the chance of unforeseen interruptions to this course of couldn’t be dominated out. As a result, the different emulsions couldn’t be processed additional. In different phrases, it was not attainable to dry them into powder. The pump diaphragm was the explanation: it was usually too delicate to resist the stress positioned on it when starting up the pump and would rupture. Replacing the diaphragm lowered the system’s service life and sometimes meant that trouble-free operation couldn’t be assured.
FINDING THE RIGHT PARTNER
In the course of searching for a dependable alternative, DSM received in touch with the Swiss subsidiary of pump producer Lewa.
“We have been already familiar with Lewa Nikkiso Switzerland as a supplier of robust techniques with lengthy service lives in the SFP sector. To guarantee trouble-free spray drying, we thought it might be smart to hitch forces with the consultants from Lewa and give you a design to solve the technical problems,” says Ibald.
DSM is committed to continually enhancing its processes and investing in technology. This dedication, together with prior expertise with the quick service lives of the previous pumps, led DSM to place special give attention to reliable function and a robust design during the project planning section. The list of requirements additionally included a substantial variety of stringent hygienic provisions that needed to be fulfilled.
“Certain meals have provisions regarding microbiological purity that are many occasions extra stringent than those for producing different meals products,” explains Ibald. “This meant that the brand new feed and booster pump had to meet these more challenging situations and each type of contamination had to be dominated out to supply the widest possible number of products on the system.”

GUARANTEED SAFE START-UP OPERATION
After a visit on the firm premises to consider the spatial and technical parameters, Lewa Nikkiso Switzerland recommended a type G3F triplex course of diaphragm pump for the spray tower utility. This pump includes a completely safe start-up operation, since a spring continuously holds the built-in sandwich diaphragm situated in a neutral position.
This protects the diaphragm against incorrect positioning and prevents it from being damaged while the pump is beginning up, increasing system availability substantially. And the Lewa triplex is managed using a strain reduction valve that is installed in the hydraulic part and can be configured for the specific state of affairs. Therefore, the pump could be adapted to different operational situations so as to stop any overloads that may arise. This ensures that the unit has a long service life and smooth regular operation for the entire system.
THE POWER OF DESIGN
In addition to the strain aid valve and the spring management, the design of the diaphragm additionally performs an essential function in ensuring reliable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which might be extremely long-lasting. They are connected to every other via constructive interlocking during the discharge stroke and mechanical force-fitting during the suction stroke.
This makes the pump hermetically tight and effectively prevents exterior contamination. As an extra safety feature, the DPS monitoring system from Lewa constantly screens the condition of the diaphragm. The monitoring unit promptly shows any injury to the gadget that leads to elevated stress within the diaphragm space.
This makes it possible to carry out preventive upkeep and repair work earlier than the diaphragm even begins to rupture and doubtlessly contaminates the pumped fluid. Thus, it is often pointless to change the pump off right away, which means that neither the pumping process nor spray drying are negatively impacted to a major extent. If damage to a diaphragm is detected, production can continue with none issues as much as a deliberate maintenance stop. The parts can then be replaced shortly and easily by releasing the cassette for the meeting.
ASEPTIC, FDA-COMPLIANT OPERATION
The hermetically tight design of the method diaphragm pump does extra than simply ensure dependable steady operation. It is also a central component for fulfilling the stringent hygiene provisions that the spray tower software is topic to. The Lewa triplex maintains a hermetically tight house with out dynamic seals, guaranteeing completely clean and aseptic manufacturing conditions. All pump heads that come into contact with the product are additionally electropolished, which makes it possible to ensure FDA-compliant pump operation.
Because the pump can be cleaned in place (CIP) using completely different alkaline and acidic brokers and with out prior dismantling, it’s possible to satisfy the particular necessities for child meals as properly. The provisions for baby meals are 1,000 times more stringent than these for other products in the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleaning, we were able to rule out any contamination of the pumped medium and clearly meet the required hygiene standard.
QUICK RESPONSE TIMES AND WELL-FOUNDED EXPERTISE
The first quote was obtained in June of 2018 and in September of the identical year, DSM Nutritional Products AG positioned an order for the triplex course of diaphragm pump. In operation since April 2019, the pump has turn into an indispensable a part of manufacturing on the plant in Sisseln.
“In each phase of the challenge, Lewa Nikkiso Switzerland demonstrated quick response occasions and well-founded experience, which made a key contribution to implementing the project efficiently,” says Ibald. “Our specs with regard to high quality, robustness, and hygiene were adopted to the letter in this challenge. As a end result, our production has turn into noticeably extra efficient and reliable.”
