Introducing a Breakthrough Constant Pressure System: Transforming the Measurement of Clogging Potential in Wine Filtration

The wine industry uses filtration systems to remove particles that could compromise the quality of wine before bottling. These systems, based on surface filtration media, trap particles that cause a clogging effect reducing the available area and decreasing the bottling flow rate. This clogging has a significant economic impact, as it deteriorates production times and increases operational costs, mainly due to higher labor demands. To obtain timely information on the performance of the filtering and bottling system, the industry uses indicators such as the maximum volume index, the filtration index, and the modified filtration index, which measure clogging potential. These are obtained through laboratory tests conducted at constant pressure under controlled conditions to replicate the industrial process. Traditional de-vices use pressurized tanks, where an inert gas at 30 psi pushes the fluid through a filter disc. However, these systems have disadvantages, such as requirement of intensive operational han-dling and the associated risks with high pressure devices. To address these challenges, a new constant-pressure system for wine filtration testing was de-veloped, utilizing a pneumatic pumping system without the need for a pressurized tank. This device, equipped with pressure regulators and hydraulic connections, reduces analysis time by 66.2% while improving operational safety. The validation of the device included statistical anal-yses showing that the samples processed by both devices were statistically similar. Additionally, a user survey revealed a high level of satisfaction with the new device compared to the traditional pressurized tank system. This approach has led to a tangible solution that is closely aligned with the specific needs of the industry, highlighting the practical application of scientific knowledge to address real industry challenges.
