Everything You Wanted to Know About Piston Fillers

Did you know your favorite salsa was filled using a piston filler? Piston fillers are an essential part of the manufacturing industry that contributes $2.3 trillion to the U.S. GDP. It’s no wonder such a massive industry relies on heavy-duty and efficient machinery to produce daily food essentials.

If your business is part of the manufacturing industry, keep reading to learn more about piston fillers and receive professional recommendations on the most affordable automated piston filler options.

What Is a Piston Filler?

In general, piston fillers are used to fill different-sized containers with sauces, beverages, dressings for salads, beauty products, sanitizers, liquid soaps, cleaning supplies, paint, and so on. The piston filler works on electricity, though some models work without it.

Usually, an employee handles the machine to place different volumes of product into containers.

Is a Piston Filler Reliably Accurate?

Piston fillers are completely accurate, which is why almost every manufacturing business dealing with large quantities of products uses piston fillers to fulfill orders and keep manufacturing at pace. Moreover, piston fillers are sanitary machines, making them ideal for the food-processing industry as well.

Understanding Different Types of Filling Machines

Piston Fillers

A piston filler with a rotary valve can easily fill containers with potato salads, salsas, peanut butter, cottage cheese, and other dense products. The amount of filling in the machine’s cylinder can be increased or decreased by tweaking the piston’s stroke length—this is usually done by rotating a handwheel to lengthen or shorten the filling stroke.

By retracting, the piston draws product from the supply tank and fills the cylinder. After being fully retracted (or retracted to a custom-set point), the piston returns to the cylinder and fills the supply line, going into the fill heads and producing the end product.

Overflow Fillers

As opposed to filling for volume or weight, an overflow filler operates with a nozzle that overflows product into a holding tank once the liquid has reached a designated level in the container. All containers are then filled identically.

In addition to achieving precise fill levels, overflow fillers are also ideal for filling foamy or carbonated liquids. The overflowing action allows any foam or air bubbles to escape before the container is sealed, resulting in a more consistent and visually appealing final product.

Rotary Cup Fillers

A rotary cup filler operates with the help of a vacuum-boosted cup de-nester to streamline the cups to the carrier plates. Afterward, the cups are carried to the filling station, waiting to be filled with the product. Once the product fills in, it is then weighed to help determine how much liquid should be filled per cup. After filling, a lid may be placed on top of the cup before discharging onto a conveyor belt.

Pail-Filling Lines

Pail-filling lines are part of the manufacturing line and are intended to accurately and reliably fill pails of products, keeping track of weight or volume. Essentially, a row of filled pails is carried to the position where lids are placed on the top of the pail and then carried through a tunnel for the lids to be pressure-pressed. Some of the most advanced pail-filling systems may include additional components such as a de-nesting system to avoid jams and bypass conveyors to handle overflow.

Different types of filling machines cater to various product needs and production requirements. Whether it’s for filling dense products in containers or achieving precise fill levels, there is a filling machine designed to meet your specific needs.

Benefits of Piston Filling Machines

Piston filling machines have numerous benefits that make them a preferred choice for industries requiring precise and efficient packaging solutions. These benefits include:

• High Fill Accuracy: Piston fillers deliver exceptional product fill accuracy, ensuring each container is filled with the exact amount of product, minimizing waste, and maximizing consistency across product lines.
• Versatility: Suitable for a range of products from liquids to thick semi-liquids and even particulate products, making them versatile for various industries like bakery, cosmetics, food & beverage, household, and industrial sectors.
• Durability and Quality Construction: Constructed using 316L stainless steel and top-quality USDA/FDA-approved materials, these machines are built to last and meet stringent hygiene standards.
• Customization: They can be tailored to specific production needs or to accommodate unique packaging requirements, providing flexibility in production processes.
• Integration Capability: Easily integrated into fully automatic packaging lines or used as standalone semi-automatic units, offering scalability as business needs grow.
• Reduced Product Degradation: The technology ensures the lowest level of product degradation, preserving the quality of the product throughout the filling process.
• Clean, Drip-Free Depositing: Designed for clean and precise depositing, reducing mess and product waste during the packaging process.
• Operational Efficiency: Features like complete dispensing control, automatic fill weight adjustment, and reduced air consumption contribute to operational efficiency and cost savings.
• Wide Compatibility: Their compatibility with a wide range of products and textures further enhances their applicability across different sectors.
• Ease of Maintenance: The stainless steel, tool-less design facilitates easy maintenance, ensuring the machines remain in optimal condition with minimal downtime.

These advantages underscore why Volumetric Technologies’ piston filling machines are recognized for their fast, accurate, and durable performance, supporting businesses in maintaining high standards of product quality and packaging efficiency.
