The Swiss subsidiary of Dutch firm DSM Nutritional Products AG uses the spray drying method when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The procedure uses pump know-how to convey numerous emulsions into a sprig tower, the place they are dried into powder. But the feed and booster pump that was getting used proved to be an uncertainty factor as a outcome of the diaphragm required for the pumping course of tended to tear when the pump was began up. Generally, such manufacturing interruptions can be corrected through immediate upkeep and restore work.
However, it is very expensive to replace a diaphragm or a whole system. DSM was looking for an alternate and eventually made a find once they talked to the pump experts at Lewa Nikkiso Switzerland, who recommended a Lewa triplex course of diaphragm pump for the spray tower software. The drive unit includes a safe start-up mode that retains the diaphragm positioned in the neutral position, and steady regulation utilizing an built-in monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it is simple to satisfy the food industry’s stringent hygienic provisions.
one hundred PERCENT INTEGRATION
“Pump know-how plays a central function in drying oil-in-water emulsions for the meals and pharmaceutical industries. These emulsions contain substances such as nutritional 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 method chain, every pump is 100% built-in into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With the previous system, the chance of unexpected interruptions to this process couldn’t be ruled out. As เกจวัดแรงดันปั๊มลมpuma , the totally different emulsions could not be processed additional. In other phrases, it was not attainable to dry them into powder. The pump diaphragm was the rationale: it was often too delicate to resist the stress placed on it when beginning up the pump and would rupture. Replacing the diaphragm reduced the system’s service life and typically meant that trouble-free operation couldn’t be assured.
FINDING THE RIGHT PARTNER
In the course of looking for a reliable different, DSM obtained in contact with the Swiss subsidiary of pump producer Lewa.
“We had been already familiar with Lewa Nikkiso Switzerland as a supplier of robust systems with lengthy service lives in the SFP sector. To guarantee trouble-free spray drying, we thought it might be sensible to hitch forces with the specialists from Lewa and come up with a design to solve the technical issues,” says Ibald.
DSM is dedicated to continually bettering its processes and investing in expertise. This commitment, together with prior experience with the short service lives of the previous pumps, led DSM to place special concentrate on reliable function and a robust design through the challenge planning section. The listing of necessities also included a substantial variety of stringent hygienic provisions that needed to be fulfilled.
“Certain foods have provisions regarding microbiological purity that are many occasions extra stringent than those for producing other meals merchandise,” explains Ibald. “This meant that the brand new feed and booster pump needed to meet these tougher circumstances and every kind of contamination needed to be dominated out to provide the widest attainable variety of products on the system.”

GUARANTEED SAFE START-UP OPERATION
After a go to 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 software. This pump contains a completely secure start-up operation, since a spring constantly holds the integrated sandwich diaphragm positioned in a impartial position.
This protects the diaphragm in opposition to incorrect positioning and prevents it from being broken while the pump is starting up, growing system availability substantially. And the Lewa triplex is managed using a strain reduction valve that is installed within the hydraulic part and could be configured for the precise situation. Therefore, the pump may be adapted to different operational conditions so as to stop any overloads that will arise. This ensures that the unit has a protracted service life and clean common operation for the complete system.
THE POWER OF DESIGN
In addition to the stress relief valve and the spring control, the design of the diaphragm also plays an essential function in guaranteeing reliable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms that are extraordinarily long-lasting. They are related to one another by way of optimistic interlocking through the discharge stroke and mechanical force-fitting in the course of the suction stroke.
This makes the pump hermetically tight and successfully prevents external contamination. As a further security feature, the DPS monitoring system from Lewa continuously displays the condition of the diaphragm. The monitoring unit promptly displays any injury to the gadget that results in elevated strain within the diaphragm area.
This makes it possible to hold out preventive upkeep and repair work before the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it’s normally unnecessary to switch the pump off instantly, which implies that neither the pumping course of nor spray drying are negatively impacted to a major extent. If harm to a diaphragm is detected, production can proceed without any problems as a lot as a deliberate upkeep stop. The components can then be replaced rapidly and simply by releasing the cassette for the meeting.
ASEPTIC, FDA-COMPLIANT OPERATION
The hermetically tight design of the method diaphragm pump does extra than just ensure dependable continuous operation. It can additionally be a central element for fulfilling the stringent hygiene provisions that the spray tower utility is subject to. The Lewa triplex maintains a hermetically tight space with out dynamic seals, guaranteeing utterly clean and aseptic production conditions. All pump heads that come into contact with the product are also electropolished, which makes it possible to make sure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) utilizing totally different alkaline and acidic brokers and without prior dismantling, it is attainable to satisfy the particular necessities for baby meals as nicely. The provisions for baby food are 1,000 occasions more stringent than these for other products within 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 same yr, 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 half of manufacturing at the plant in Sisseln.
“In every phase of the challenge, Lewa Nikkiso Switzerland demonstrated quick response times and well-founded experience, which made a key contribution to implementing the venture efficiently,” says Ibald. “Our specifications with regard to quality, robustness, and hygiene have been adopted to the letter on this project. As a end result, our manufacturing has turn into noticeably more efficient and dependable.”
