The Swiss subsidiary of Dutch company 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 technology to convey various emulsions into a twig tower, the place they’re dried into powder. But the feed and booster pump that was being used proved to be an uncertainty factor as a end result of the diaphragm required for the pumping process tended to tear when the pump was started up. Generally, such production interruptions can be corrected by way of immediate upkeep and repair work.
However, it is rather costly to replace a diaphragm or a complete system. DSM was in search of another and at last made a discover after they talked to the pump experts at Lewa Nikkiso Switzerland, who beneficial a Lewa triplex process diaphragm pump for the spray tower utility. The drive unit features a protected start-up mode that retains the diaphragm situated in the neutral place, and continuous regulation utilizing an integrated monitoring system. Since the hermetically tight pumps are electropolished and CIP-approved, it’s simple to satisfy the food industry’s stringent hygienic provisions.
100 PERCENT INTEGRATION
“Pump technology performs a central role in drying oil-in-water emulsions for the meals and pharmaceutical industries. These emulsions include substances such as nutritional vitamins, carotenoids, or polyunsaturated fatty acids as lively ingredients,” explains Natalie Ibald, plant manager of formulations at DSM Nutritional Products AG. “As a half of the process chain, every 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 earlier system, the risk of unexpected interruptions to this process couldn’t be dominated out. As a end result, the totally different emulsions couldn’t be processed additional. In other phrases, it was not potential to dry them into powder. The pump diaphragm was the explanation: it was typically too delicate to face up to the stress placed on it when starting up the pump and would rupture. Replacing the diaphragm decreased the system’s service life and typically meant that trouble-free operation couldn’t be guaranteed.
FINDING THE RIGHT PARTNER
In the course of searching for a dependable various, DSM obtained in touch with the Swiss subsidiary of pump manufacturer Lewa.
“We had been already conversant in Lewa Nikkiso Switzerland as a supplier of sturdy techniques with long service lives in the SFP sector. To ensure trouble-free spray drying, we thought it will be good to join forces with the specialists from Lewa and give you a design to unravel the technical issues,” says Ibald.
เกจวัดแรงดันออกซิเจนราคา is committed to repeatedly bettering its processes and investing in expertise. This dedication, along with prior experience with the short service lives of the previous pumps, led DSM to position particular focus on reliable operate and a robust design in the course of the project planning section. The list of necessities additionally included a considerable number of stringent hygienic provisions that had to be fulfilled.
“Certain meals have provisions regarding microbiological purity that are many instances extra stringent than these for producing different food products,” explains Ibald. “This meant that the model new feed and booster pump needed to meet these tougher conditions and every type of contamination had to be ruled out to produce the widest attainable number of merchandise on the system.”

GUARANTEED SAFE START-UP OPERATION
After a visit at the company premises to consider the spatial and technical parameters, Lewa Nikkiso Switzerland recommended a kind G3F triplex process diaphragm pump for the spray tower software. This pump features a utterly secure start-up operation, since a spring continuously holds the integrated sandwich diaphragm situated 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, increasing system availability substantially. And the Lewa triplex is managed utilizing a strain relief valve that is installed within the hydraulic part and may be configured for the particular situation. Therefore, the pump could be tailored to different operational situations in order to forestall any overloads that may 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 strain aid valve and the spring management, the design of the diaphragm also plays an necessary function in making certain dependable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which are extraordinarily long-lasting. They are linked to every other by way of constructive 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 an additional safety characteristic, the DPS monitoring system from Lewa repeatedly monitors the situation of the diaphragm. The monitoring unit promptly shows any harm to the gadget that leads to elevated stress within the diaphragm area.
This makes it potential to carry out preventive upkeep and repair work earlier than the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it is usually pointless to change the pump off instantly, which signifies 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 with none problems up to a planned upkeep cease. The components can then get replaced shortly and easily by releasing the cassette for the assembly.
ASEPTIC, FDA-COMPLIANT OPERATION
The hermetically tight design of the method diaphragm pump does extra than simply guarantee reliable continuous operation. It can be a central component for fulfilling the stringent hygiene provisions that the spray tower application is topic to. The Lewa triplex maintains a hermetically tight area without dynamic seals, guaranteeing utterly clean and aseptic production situations. All pump heads that come into contact with the product are also electropolished, which makes it attainable to make sure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) utilizing completely different alkaline and acidic brokers and with out prior dismantling, it’s potential to fulfill the special requirements for child food as properly. The provisions for child meals are 1,000 occasions more stringent than those for other products in the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleansing, we have been capable of 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 acquired in June of 2018 and in September of the same 12 months, DSM Nutritional Products AG positioned an order for the triplex course of diaphragm pump. In เครื่องมือตรวจวัดความดันเลือดเรียกว่า since April 2019, the pump has turn out to be an indispensable part of manufacturing on the plant in Sisseln.
“In every phase of the venture, Lewa Nikkiso Switzerland demonstrated fast response occasions and well-founded expertise, which made a key contribution to implementing the challenge successfully,” says Ibald. “Our specs with regard to high quality, robustness, and hygiene had been adopted to the letter in this challenge. As a result, our production has become noticeably extra efficient and dependable.”
