    6. How a Chemical Filling Machine Works?

    The chemical filling machine has the same working principle as that of other liquid filling machines. However, every working step, in this machine is carefully controlled by different computerized controls to ascertain fill accuracy in every container. The stages in the working of a chemical filling machine are:

    Chemical Filling Machine Works

    Chemical Filling Inside Hopper

    At first, the large volume of chemicals is loaded inside the infeed hopper by the operator. This step is usually carried out before starting the machine.

    Container Loading

    Secondly, the operator stockpiles a bulk load of empty containers such as jerrycans, pails, drums, etc in the feeding device. This part automatically places the container in a row on the moving conveyor. These empty packaging containers are also positioned on the conveyor by the operator.



    When the empty container reaches the filling head, the PLC system signals for opening valves which then move chemicals from the hopper to filling nozzles. At first, chemicals are dispensed at higher rates in containers. Once a pre-set volume, weight, or level is reached, the filling rate slows down.

    At this stage, filling nozzles partially close for loading the chemicals at reduced speed. This process is carried out to attain precision in every fill.

    Container Discharge

    Container Discharge

    After complete filling, the PLC signals to close valves and also to remove the filled container from the filling unit. These filled containers are then moved to the capping or sealing area for their permanent closing.

    7. What Is the Auxiliary Equipment of a Chemical Filling Machine?

    The chemical filling production line consists of different machines that are in complete synchronization for performing efficient, timely, and seamless packaging of chemicals. The auxiliary equipment that forms the chemical processing line differs from other machines involved in traditional liquid filling.

    It can dose both thin viscosity or free-flowing liquids and gluey chemicals like glues and Vaselines.

    10. How Chemical Filling Machine Is Different from Traditional Filling Machine?

    Chemical Filling Machine-1

    Both chemical filling machines and traditional filling machines load liquids in containers for easy shipment and delivery. However, the body construction of a chemical filling machine is designed to guarantee absolute-maximum chemical security and safety.

    Manufacturers can rely on this equipment because it has an Extremely Corrosion Resistant construction for processing highly reactive chemicals such as acids and alkalis.

    The body of the chemical filling machine is constructed using A4 or 316 stainless steel that contains molybdenum in addition to nickel, iron, and chromium. This metal alloy offers a high level of corrosion protection that make this material highly suitable for handling chemical solution. Moreover, even though, this equipment is involved in the filling of reactive chemicals, it is completely safe for both the operator and the working environment.

    11. What Are the Different Fillers of a Chemical Filling Machine?

    The chemical filling process is quite complicated and should be performed with caution to achieve safe dosing. The fillers in the chemical filling machine assist in accomplishing this feat. There are various types of fillers, each has its filling mechanism. These different kinds of fillers are detailed below:

    Isobaric Pressure Fillers

    Isobaric Pressure Fillers

    It is also known as counter-pressure or bottom-up fillers. They generate back pressure in the container to counter the pressure produced in the hopper and control the depressurization of the tank for lowering foamy or overflow of chemicals.

    Isobaric pressure filler deposits carbonated drinks, beer, and water with a bottom-up nozzle that goes all the way to the container base.

    Pump Fillers

    Pump Fillers

    Pump fillers are installed in the chemical filling machine for accuracy in volumetric filling. Different kinds of pumps, for instance, cavity pumps, lobe pumps, etc., assist in the fluidity of chemicals through nozzles.

    In time-based pump fillers, chemicals are dispensed in the containers for a pre-determined time while in pulse-based pump fillers chemicals are pumped in the container for a specific number of gear revolutions. For the optimized filling, each filling nozzle is equipped with its pump.

    Over-Flow Fillers

    Over-Flow Fillers

    Rather than filling the container by weight or volume, these fillers load the container up to a certain level. Spacers in the overflow nozzle assist in filling containers to a particular level.

    The residual chemical is sent back to the hopper through an orifice in the overflow nozzle after a certain level of filling is attained. However, the limitation of overflow filler is the slight difference in the volume of each container.

    Gravity Fillers

    Gravity Fillers

    Gravity fillers consist of a raised tank and filling heads. Chemicals flow from the raised hopper to the filling unit under the influence of gravitational force. Valves are present in the filling unit that open when filling is needed. These valves are ajar for a pre-set time and are closed when said time is reached.

    They are perfect for filling free-flowing chemicals such as water.

    Piston Fillers

    Piston Fillers

    As the name suggests, these fillers are equipped with pistons for dispensing chemicals. The forth-and-back motion of a piston in a cylinder helps in obtaining accuracy in every fill. Chemicals are pushed into the cylinder with a forward motion of the piston while its backward movement forces chemicals into the filling nozzle.

    Piston fillers are ideal for filling viscous chemicals.

    Net Weigh Fillers

    Net Weigh Fillers

    They are different from other types of filler since they dose containers by the measure of weight instead of volume. The weight is programmed on the HMI screen before filling while the weighing scale present at the bottom of the conveyors, calculates the filling weight. Once the required weight is achieved, the filling process stops.

    Net weigh fillers are specially designed for handling abrasive, violent, and expensive chemicals. They are more accurate than other fillers.

    12. What Is the Special Safety Device for a Chemical Filling Machine?

    Special Safety Device

    A good chemical filling machine is equipped with the special safety feature of ‘an-anti-explosion device’. The following device is meant for protection. During the chemical filling process, the machine produces heat, so an internal system of wiring, electrical coiling, motor, and tubing is shielded with explosion proof material for safe operation.

    This is enclosed in explosion-proof cabinet which is also known as a fire-retardant cabinet. The material of this cabinet is composed of double-layered steel with fireproof and anti-corrosive material which ensures users 100 percent safety during work.
    The following material has an affinity to resist heat up to 700ºF while around 930ºF material starts losing its strength against heat.

    So, in the chemical industry where frequent handling of chemicals such as bleach, acids, bases, and flammable compounds are in abundant, you must use filling equipment that is equipped with anti-explosion device to reduce risks of ignition or fire.

    13. How You Can Increase the Efficiency of a Chemical Filling Machine?

    For higher machine efficiency, better quality fills, and higher filling speed you can customize your chemical filling machine in several ways including:

    Nozzle Adjustment and Compatibility

    Nozzle Adjustment and Compatibility

    Nozzle selection and adjustment go a long way in boosting the efficiency of the chemical filling machine. A bigger orifice nozzle is better for bulk-capacity containers since they dose more filling volume.

    Moreover, for lowering the chance of foaming and dripping, it is suggested to use bottom-up nozzles for foamy chemicals. These nozzles go deep inside the container and increase the production rate.

    Choosing Best Tubing

    Choosing Best Tubing

    Yes, tubing is surely useful in increasing the efficiency of a chemical filling machine. Equipping your machine with the right kind of tubing that is corrosive and chemical-resistant reduces its wear and tear which in turn increases the production rate of the equipment.
