### Limitations of Current Constant Pressure Systems  
The use of the constant pressure device presents significant limitations that impact both efficiency and safety in industrial environments. Due to the nature of the current test, it is necessary to extract a sample from the finished product tank and transport it to the laboratory for analysis. The device allows for a fixed volume of sample as it needs to fill the pressurized tank independently and cannot be connected to the production line. This is particularly important as it imposes a limitation in dynamic processes, wherein a single 500 mL sample may not accurately represent the entirety of a lot that can exceed 100,000 L [14].  
Additionally, the use of a pressurized tank at 30 psi poses safety risks for the operator, such as potential hazards from pressure release or handling errors. If the procedure for relieving pressure is not properly followed or if any part of the system fails or becomes dislodged, the operator could suffer serious injury due to the sudden release of pressure. This inherent risk in handling pressurized systems requires careful operation to prevent accidents [20].  
Lastly, the required time to perform an analysis with this device is considerable, as more than 70% of the total time is spent on setup tasks such as cleaning, depressurizing the tank, and preparing the next sample. This reduces efficiency in production environments where fast, continuous measurements are needed, limiting the ability to frequently analyze during the filtration and bottling process [16].  
3 Development of a System for Clogging Tests at Constant Pressure Without the Use of a Pressure Tank  
The development of a novel device designed to measure clogging potential in wine production processes is presented. It considers a constant pressure system that does not require the use of a pressurized tank. This innovation contributes to reducing operational risk, enables direct analysis of samples from the production line, and optimizes the time required for analysis by simplifying cleaning and handling processes. The following sections discuss the fundamental design principles, provide a detailed breakdown of the device's parts and components, and describe its operation. A statistical comparison, based on experimental methods, is conducted for the obtained results with the proposed device and those generated by the conventional system used in the industry. Finally, a user-level evaluation is provided regarding the performance and usability of the new device in comparison with the pressurized tank system.  
The developed device consists of a support structure and a cabinet housing the pneumatic pumping system and the control system, which is composed of valves and pressure

and flow regulators. This design allows for direct suction of a sample under atmospheric conditions and increases its pressure to the required test level, facilitating the filtration of wine samples while maintaining the pressure conditions necessary for clogging tests, equivalent to those of a pressurized tank. The pressurized liquid passes through a filter disc, and the evolution of the filtered volume over time is recorded using a graduated cylinder. This allows for the calculation of the clogging indicator based on the parameter to be evaluated Figure 3 presents a schematic view of the different elements that internally configure the device and ensure its proper functioning. Figure 4 shows the device integrated with the peripheral components. A more detailed overview of the design characteristics, functionality, and usage procedures of the device is presented below.
