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 twig tower, where 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 began up. Generally, such manufacturing interruptions could be corrected by way of immediate upkeep and repair work.
However, it is rather costly to switch a diaphragm or a whole system. DSM was in search of another and eventually made a find once they talked to the pump experts at Lewa Nikkiso Switzerland, who beneficial a Lewa triplex process diaphragm pump for the spray tower application. The drive unit includes a protected 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 straightforward to fulfill the meals industry’s stringent hygienic provisions.
one hundred PERCENT INTEGRATION
“Pump know-how performs a central position in drying oil-in-water emulsions for the food and pharmaceutical industries. These emulsions contain substances corresponding to nutritional vitamins, carotenoids, or polyunsaturated fatty acids as lively components,” explains Natalie Ibald, plant supervisor of formulations at DSM Nutritional Products AG. “As part of the method chain, every pump is 100% integrated into the closed plant system. The pumps are used for conveying the mixtures into the spray tower.”
With เกจวัดแรงดันลมคือ , the chance of unforeseen interruptions to this course of couldn’t be dominated out. As a result, the completely different emulsions couldn’t be processed further. In different phrases, it was not attainable to dry them into powder. The pump diaphragm was the reason: it was typically too sensitive to face up to the stress placed on it when beginning up the pump and would rupture. Replacing the diaphragm lowered the system’s service life and typically meant that trouble-free operation couldn’t be assured.
FINDING THE RIGHT PARTNER
In the course of searching for a dependable different, DSM obtained in contact with the Swiss subsidiary of pump producer Lewa.
“We were already familiar with Lewa Nikkiso Switzerland as a provider of strong methods with long service lives in the SFP sector. To ensure trouble-free spray drying, we thought it will be sensible to join forces with the experts from Lewa and give you a design to resolve the technical problems,” says Ibald.
DSM is committed to continually bettering its processes and investing in know-how. This dedication, along with prior expertise with the quick service lives of the previous pumps, led DSM to place special give consideration to dependable function and a robust design during the venture planning section. The record of requirements additionally included a substantial variety of stringent hygienic provisions that needed to be fulfilled.
“Certain meals have provisions relating to microbiological purity which are many instances more stringent than those for producing different food merchandise,” explains Ibald. “This meant that the model new feed and booster pump had to meet these more difficult circumstances and each sort of contamination had to be ruled out to produce the widest potential number of merchandise on the system.”

GUARANTEED SAFE START-UP OPERATION
After a go to on the company premises to suppose about the spatial and technical parameters, Lewa Nikkiso Switzerland recommended a kind G3F triplex process diaphragm pump for the spray tower utility. This pump contains a utterly safe start-up operation, since a spring constantly holds the integrated sandwich diaphragm situated in a neutral place.
This protects the diaphragm towards incorrect positioning and prevents it from being broken while the pump is beginning up, growing system availability considerably. And the Lewa triplex is managed utilizing a strain relief valve that is put in within the hydraulic part and can be configured for the specific state of affairs. Therefore, the pump can be tailored to completely different operational situations to find a way to stop any overloads that will arise. This ensures that the unit has a long service life and easy common operation for the entire system.
THE POWER OF DESIGN
In addition to the stress aid valve and the spring control, the design of the diaphragm additionally performs an important role in making certain reliable pump operation. The patented sandwich diaphragm consists of two separate PTFE diaphragms which may be extremely long-lasting. They are related to one another by way of optimistic interlocking through the discharge stroke and mechanical force-fitting through the suction stroke.
This makes the pump hermetically tight and effectively prevents exterior contamination. As a further safety characteristic, the DPS monitoring system from Lewa constantly monitors the condition of the diaphragm. The monitoring unit promptly displays any injury to the gadget that leads to elevated pressure within the diaphragm house.
This makes it possible to carry out preventive maintenance and restore work earlier than the diaphragm even begins to rupture and probably contaminates the pumped fluid. Thus, it’s often unnecessary to change the pump off immediately, which means that neither the pumping process nor spray drying are negatively impacted to a major extent. If harm to a diaphragm is detected, production can proceed with none issues up to a planned maintenance stop. The elements can then get replaced quickly and simply by releasing the cassette for the assembly.
ASEPTIC, FDA-COMPLIANT OPERATION
The hermetically tight design of the process diaphragm pump does extra than simply guarantee dependable continuous operation. It can also be a central component for fulfilling the stringent hygiene provisions that the spray tower software is topic to. The Lewa triplex maintains a hermetically tight area with out dynamic seals, guaranteeing completely clean and aseptic manufacturing conditions. All pump heads that come into contact with the product are also electropolished, which makes it potential to make sure FDA-compliant pump operation.
Because the pump may be cleaned in place (CIP) utilizing different alkaline and acidic agents and with out prior dismantling, it’s possible to satisfy the special requirements for baby food as properly. The provisions for child food are 1,000 times more stringent than these for different products in the meals sector. Thanks to the hermetically tight design, electropolishing, and CIP cleaning, 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 received in June of 2018 and in September of the same yr, DSM Nutritional Products AG placed an order for the triplex course of diaphragm pump. In operation since April 2019, the pump has turn out to be an indispensable part of production at the plant in Sisseln.
“In every section of the challenge, Lewa Nikkiso Switzerland demonstrated quick response times and well-founded experience, which made a key contribution to implementing the project successfully,” says Ibald. “Our specs with regard to high quality, robustness, and hygiene have been adopted to the letter on this project. As a outcome, our production has turn into noticeably extra environment friendly and dependable.”
