The Swiss subsidiary of Dutch firm DSM Nutritional Products AG makes use of the spray drying method when producing vitamin and carotenoid powders for the pharmaceutical and meals industries. The process makes use of pump technology to convey numerous 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 course of tended to tear when the pump was began up. Generally, such manufacturing interruptions may be corrected through instant maintenance and restore work.
However, it is extremely expensive to exchange a diaphragm or a whole system. DSM was looking for another and finally made a discover after they talked to the pump specialists at Lewa Nikkiso Switzerland, who recommended a Lewa triplex process diaphragm pump for the spray tower application. The drive unit contains a secure start-up mode that retains the diaphragm located within the impartial place, and steady regulation using an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it’s straightforward to fulfill the meals industry’s stringent hygienic provisions.
a 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 lively components,” explains Natalie Ibald, plant supervisor of formulations at DSM Nutritional Products AG. “As a half of the method chain, each pump is 100 percent integrated into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With the earlier system, the danger of unexpected interruptions to this course of couldn’t be ruled out. As a end result, the different emulsions couldn’t be processed additional. In other phrases, it was not attainable to dry them into powder. The pump diaphragm was the explanation: it was typically too delicate to resist the stress positioned on it when starting up the pump and would rupture. Replacing the diaphragm decreased the system’s service life and generally meant that trouble-free operation couldn’t be guaranteed.
FINDING THE RIGHT PARTNER
In the course of searching for a reliable different, DSM got in touch with the Swiss subsidiary of pump manufacturer Lewa.
“We have been already conversant in Lewa Nikkiso Switzerland as a provider of robust methods with long service lives within the SFP sector. To guarantee trouble-free spray drying, we thought it might be sensible to hitch forces with the consultants from Lewa and come up with a design to solve the technical issues,” says Ibald.
DSM is committed to continually bettering its processes and investing in technology. This dedication, together with prior experience with the short service lives of the previous pumps, led DSM to put particular focus on reliable perform and a sturdy design in the course of the venture planning phase. The listing of requirements also included a considerable variety of stringent hygienic provisions that needed to be fulfilled.
“Certain meals have provisions relating to microbiological purity which are many times more stringent than those for producing other meals products,” explains Ibald. “This meant that the new feed and booster pump had to meet these tougher conditions and each kind of contamination needed to be ruled out to provide the widest possible variety of products on the system.”

GUARANTEED SAFE START-UP OPERATION
After a visit at the firm premises to think about the spatial and technical parameters, Lewa Nikkiso Switzerland recommended a type G3F triplex process diaphragm pump for the spray tower utility. This pump contains a utterly safe start-up operation, since a spring continuously holds the integrated sandwich diaphragm situated in a neutral position.
This protects the diaphragm against incorrect positioning and prevents it from being broken whereas the pump is beginning up, increasing system availability substantially. And the Lewa triplex is controlled using a pressure relief valve that’s put in in the hydraulic half and can be configured for the particular state of affairs. Therefore, the pump may be tailored to totally different operational conditions so as to prevent any overloads that will arise. This ensures that the unit has a long service life and easy common operation for the whole system.
THE POWER OF DESIGN
In addition to the stress aid valve and the spring control, the design of the diaphragm also plays an necessary role in guaranteeing dependable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which might be extremely long-lasting. They are linked to one another via 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 exterior contamination. As a further security function, the DPS monitoring system from Lewa continuously screens the condition of the diaphragm. The monitoring unit promptly displays any harm to the system that leads to elevated pressure within the diaphragm area.
This makes it potential to carry out preventive maintenance and repair work earlier than the diaphragm even begins to rupture and potentially contaminates the pumped fluid. Thus, it is usually pointless to switch the pump off right away, which signifies that neither the pumping course of nor spray drying are negatively impacted to a significant extent. If harm to a diaphragm is detected, manufacturing can proceed with none issues as much as a planned maintenance cease. The elements can then be replaced rapidly and simply by releasing the cassette for the assembly.
ASEPTIC, FDA-COMPLIANT OPERATION
The hermetically tight design of the method diaphragm pump does more than simply guarantee dependable steady operation. เกจวัดแก๊สlpg can also 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 without dynamic seals, guaranteeing completely clean and aseptic production situations. All pump heads that come into contact with the product are additionally electropolished, which makes it attainable to ensure FDA-compliant pump operation.
Because the pump can be cleaned in place (CIP) using different alkaline and acidic brokers and with out prior dismantling, it’s possible to fulfill the particular requirements for child food as properly. The provisions for child food are 1,000 times extra stringent than those for different merchandise in the food sector. Thanks to the hermetically tight design, electropolishing, and CIP cleaning, we were in a position 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 yr, DSM Nutritional Products AG positioned an order for the triplex process diaphragm pump. In operation since April 2019, the pump has become an indispensable a part of production on the plant in Sisseln.
“In every part of the project, Lewa Nikkiso Switzerland demonstrated fast response occasions and well-founded expertise, which made a key contribution to implementing the project successfully,” says Ibald. “Our specifications with regard to high quality, robustness, and hygiene had been adopted to the letter in this venture. As a result, our production has turn out to be noticeably extra environment friendly and reliable.”
