Serac Slark’s (https://serac-group.com.cn/secteur/paints-and-thinners/) sauce filling machines use a weight-based filling method. Today, in the field of sauce filling, volume filling, flow metering, and weight-based filling constitute the three main technologies. Among them, weight-based filling, although not a new technology, has regained the favor of sauce and seasoning manufacturers in recent years. This technology brings many benefits to manufacturing enterprises; it can play a significant role in producing healthier products as well as improving production efficiency. This article will provide an in-depth analysis of weight-based filling machines, offering a comprehensive reference for those looking to purchase sauce filling machines. I. Precise preservation of sauce flavor and texture: In the sauce production process, flavor, texture, and appearance are the key factors that determine the consumer experience. Especially for low-fat sauces, such as more refined emulsified sauces like mayonnaise, it is a great challenge to maintain their original texture. Since different sauces have unique rheological properties, even the slightest carelessness during packaging can damage the product’s condition. The weighing filler, thanks to its technical advantages, has successfully solved this problem. During filling, it relies primarily on gravity, or applies a slight excess pressure for high-viscosity products, to minimize the impact of dynamic forces on the product. Compared to volume-based filling and flow metering techniques, weight-based filling does not apply significant pressure to the sauce, preventing damage to its texture and thus preserving the sauce’s original flavor and consistency. II. Creating a friendly filling process: In sauce filling technology, the working principles of different equipment result in significant variations in the filling process experienced by the product. In volumetric filling, the product must pass through a double feeding process and a downward stroke to enter and exit the metering chamber, while in flow metering, the product is pressurized to force it through the flow meter and a narrow tube. Weight-based filling machines (https://serac-group.com.cn/secteur/paints-and-thinners/) use gravity tanks to maintain a constant level of product load, ensuring a linear and regular flow and thus reducing viscosity loss effectively. Its product flow circuit is simple: after coming out of the processing unit, the sauce enters a small buffer tank and then is poured into the container. There is no dynamic sealing in this process, and there are few moving parts, so turbulence hardly occurs within the product, which greatly reduces the impact on the sauce. III. Effective bacterial isolation to ensure product hygiene. Today, consumers place greater emphasis on health, which has prompted manufacturers to develop new formulas with lower levels of salt and preservatives. However, such formulations are more sensitive to pathogen growth and require higher hygiene standards during the packaging process. Weighing filling machines (https://serac-group.com.cn/secteur/paints-and-thinners/) offer significant advantages in terms of hygiene, as they utilize aseptic filling processes. Its filling nozzle is fully open and drains water 100% on its own, remaining clean throughout the entire filling process. Unlike volumetric filling, the filling valve never comes into contact with the container, eliminating the risk of contamination. Taking Serac’s weighed filling system as an example, the design of the entire product circuit takes into account ease of cleaning; metal-to-metal valves are used to minimize the number of mechanical components that come into direct contact with the product, and together with efficient CIP systems, thorough cleaning is achieved. Furthermore, the equipment operates in a closed hygiene circuit, utilizing multi-directional hygiene spray nozzles to enhance the impact force of the liquid jets. The water tank drains completely by itself, eliminating any dead corners that could harbor contaminants, thus effectively preventing the growth of pathogens in sensitive formulations. IV. Significantly improve production efficiency and flexibility: As consumers’ demand for various types of sauces grows more diverse, manufacturers need more flexible equipment to optimize production transitions. Weighing fillers perform excellently in this regard; they are suitable not only for hot (60 – 80°C) and cold preparation but also for handling non-conductive, aerated, or heterogeneous products, something that is difficult to achieve with inductive and mass flow metering. In the packaging stage, weight-based filling technology (https://serac-group.com.cn/secteur/paints-and-thinners/) offers greater flexibility, allowing a ratio of 1 to 20, which far exceeds the limit of 1 to 6 for volume filling. This means that one production line can fill formulations in up to 20 different packaging sizes. Furthermore, the weighing filling machine has a simple product circulation system, which allows for savings in drainage time and product usage at the end of each batch, while also reducing the time and water required for cleaning. When the physical properties of the products vary, it is easier to calibrate the weight parameter, which significantly improves production efficiency. The key difference between weight-based filling and other technologies lies in the measurement process: mass flow metering measures the amount of product that passes through the flow meter, whereas weight-based filling is the only technology that can control the weight inside the container after the product has passed through the nozzle. For a long time, weight-based filling has held an important position in the sauce filling industry thanks to its accuracy and ability to prevent product loss. In summary, whether one aims to increase the production of low-fat, preservative-free products or to diversify the range of formulations available on the packaging line, a gentle, clean, and flexible weighing filling machine is an ideal choice for sauce and seasoning manufacturers.
