Jar Filling Machine, A Wide Range Of Jar Filling Solutions

Jar is a container for packing liquids or small particles, and is the choice of many packagers. In this article, we will learn more about the filling solutions for a wide variety of jars.

What is a Jar?

A jar is a rigid, cylindrical or slightly conical container, typically made of glass, ceramic, or plastic, with a wide mouth or opening that can be closed with a lid, screw cap, lug cap, cork stopper, roll-on cap, crimp-on cap, press-on cap, plastic shrink, heat sealed lidding film, an inner seal, a tamper-evident band, or other suitable means. Generally, a jar has a cylindrical shape with a mouth about the same diameter as the cylinder, and a bottle has a tapered neck leading to a mouth much smaller than the cylinder (So there is another way to say it: a jar is a wide-mouthed bottle). Bottles and jars can have non-cylindrical shapes, but can still be distinguished by wide mouth verses narrow mouth.

There are many products on the market that are packaged in jars. Common ones are various sauces, such as mayonnaise, peanut butter, chili sauce, etc. In addition, honey, creams, lotions, cosmetics, etc. are often packaged in jars. Some of the videos of jar filling machines made by VKPAK are listed below.

Semi Automatic Jar Filling Machine

This machine is a semi-automatic piston type paste jar filling machine, easy to operate, applicable to a wide range, commonly used in: food sauce, cosmetics, creams, lotions, edible oil, lubricants, honey, syrup and other viscous or paste materials.

The whole machine is made of high quality stainless steel, and the shape is novel and beautiful. And the quantitative is correct, the dispensing error is small, and the adjustment is simple. It is the most ideal small-sized equipment for small-dose liquid quantitative dispensing in hospitals, pharmaceutical factories, beverage factories, daily chemical plants, scientific research experiments, etc. Usually, the semi-automatic liquid filling machine divided into single filling Nozzle or double filling nozzle according to the needs of different customers.

Types Of Jar Filling Machines

According to the degree of automation of the filling machine, or according to the output to divide the jar filling machine can be divided into semi-automatic and automatic filling machine. In general terms, automatic equipment will require little to know interaction with an operator once the machine is set up and running. Semi-automatic equipment will require a more hands on approach, with an operator assisting the machine at every cycle.

Semi-Automatic Jar Filling Machine

Semi-automatic jar fillers require the operator to correctly place containers under the fill nozzles and start the fill cycle, which is usually done via foot or finger switch. Once filled, the operator removes the containers and transfers them to the next packaging phase or machine. With filling machines, some semi-automatic processes may also require the operator to replenish product from time to time as well. The speed of semi-automatic jar filling machines will depend on the operator speed as well, whereas automatic machines with power conveyors can consistently, reliably and repeatedly achieve a certain speed.

Automatic Jar Filling Machine

Filling machines introduce the product to the containers via a bulk source or supply tank on the machine itself. Operators of automatic jar filling machines will need to ensure PLC settings are correct and make adjustments to conveyors, fill heads and other components as necessary. But again, once the automatic filler is running, the operator’s main task will be to monitor the machine and the packaging line.

According to the metering principle, Jar filling machines can be divided into overflow filling machines, gravity filling machines, pump filling machines, piston filling machines and net weight filling machines, where overflow filling is typical of liquid level filling, while the other types of filling machines are all quantitative: gravity filling is time-based; pump filling is time or pulse-based; piston filling is volume-based and net weight filling is weight-based.

Overflow Jar Filling Machine

The overflow filler serves a number of different industries and is extremely popular with those packagers who use clear jars for their products. These filling machines are a popular item for clear containers because the machine fills each jar to the same level, even where the interior volume of the container varies slightly from one to the next.

The overflow filler achieves this level fill by using a special nozzle that seals over the jar opening. One port in the nozzle releases product in to the jar once the seal is attained. When the product reaches the desired level in the jar, a second port allows the liquid to “overflow” out of the jar and back in to circulation. This method of filling also works well with foaming products, as the release of product into the jar helps control and remove the foam. Though ideal for clear containers, the control of the foam and the level fill mean that this liquid filler can be used for a variety of products in a range of industries. However, these liquid fillers are better for thin, free-flowing products, as higher viscosity liquids simply would not flow fast enough to make this an efficient solution.

Gravity Jar Filling Machine

Gravity filling machines offer a simple way to achieve an accurate volumetric fill. Product is held in a tank above the fill heads and, as the name suggests, gravity is used to move product into the waiting jars. Valves will open and close according to pre-set times during which liquid will be released to allow each jar to reach the desired volume. On VKPAK machines, the fill time (or time that the valve is open to allow product in) can be set for each individual head, allowing for added accuracy.

Pump Jar Filling Machine

Whether filling your jars using a time or pulse based method, pump filling machines are ideal filling machines for thicker products and some products that contain particulates. A time based filling method will simply fill by allowing the pump to run for the same length of time each fill cycle. A pulse based filling system will not utilize time, but will measure revolutions or movements of the pump. For example, a “pulse” on a gear pump would be a revolution or partial revolution of the gear.The type of pump used on the filling equipment will be determined by the product being filled.

Pump filling machines offer the versatility to handle not just thin products, but also higher viscosity products as well. The pumps used on these liquid fillers will be matched to the project on a case-by-case basis, allowing the packaging machine to be manufactured with the pump that best suits each individual project. Pump fillers can also handle products with particulates such as salad dressings or soaps with grit. A variety of nozzles can also be used on the pump filler to match the specific application for which the machine is built.

Piston Jar Filling Machine

Piston filling machines are an incredibly versatile type of filler in that they can handle products both thick and thin, including products with particulates or chunks (think tomato paste or jams and jellies with pieces of fruit). Given the principle behind the piston filler, they also offer a highly accurate volumetric fill. These two attributes alone can make a piston filler the ideal filling machine for a great number of packaging projects.

In general, the piston will retract from the cylinder, allowing the cylinder to fill up with product. The actual length that the piston will retract can be adjusted by the operator of the filling machine. However, once that retraction point is set, each cycle will bring the same amount of product into the piston filler cylinder. Once product fills the cylinder, the piston will move forward, pushing product out of the cylinder, through a combination of tubes and/or nozzles, and into the waiting containers. Since the retraction point of the piston is the same each cycle, and the end point or push point of the piston is the same each cycle, the same volume of product will enter and exit the cylinder each cycle, giving the piston filling machine its reputation as an accurate liquid filler.
