PT Arasains recently held a successful webinar titled "Vaisala Online Refractometer and Weiliang Sieving for Various Industrial Applications," introducing two innovative brands and their technologies. The event took place on 27 June 2024 and attracted industry users from diverse sectors such as Food & Beverage, Chemicals, Palm Oil, Pharmaceutical and others. Mr. Alvin Yoong, Regional Sales Manager (APAC) for Vaisala Sdn Bhd, presented the Vaisala Online Refractometer, highlighting its capabilities in measuring physical properties of a product in Brix, Baume, dissolved solids, and product concentration accurately. This technology, installed directly on production lines, allows for real-time concentration measurements, allowing corrective actions to be taken promptly. Mr. James Wong, Managing Director of Weiliang Singapore Pte Ltd, delivered an insightful presentation on the fundamentals of sieving. He explained the sieving process and highlighted the critical role of mesh size in ensuring effective separation. During his talk, James engaged the audience by posing a question about mesh measurement: should it be understood as referring to square inches or linear inches? He clarified that mesh size is measured in linear inches, which is crucial for selecting the right sieving model to meet specific industrial requirements. Weiliang's products provide versatile solutions, offering both solid sieving and wet screens for liquid-solid separation. The webinar featured active audience engagement, with participants raising questions during the Q&A sessions. Attendees inquired about the application of Vaisala's technology in measuring salt concentration in margarine, Baume in plating chrome solutions, and Brix in syrups and honey. Alvin explained how Vaisala measures the refractive index which then converted to Brix, and that readings are not affected by particles nor bubbles. For the Weiliang segment, questions covered topics such as machine surface roughness, wetted material options, and troubleshooting existing sieving issues. James Wong provided insightful answers, demonstrating the versatility and efficiency of Weiliang's sieving technology.
