DESCRIPTION

A semi-automatic volumetric liquid filling machine is a type of machine that accurately fills containers with liquids based on a pre-set volume, using a piston or rotary valve to measure the liquid and a nozzle to dispense it. It is semi-automatic because it requires manual loading and unloading of containers, while the filling process itself is automated. These machines are commonly used in industries like pharmaceuticals, food and beverage, and cosmetics for filling bottles, vials, and other containers with various liquids.

KEY FEATURES AND ADVANTAGES

Volumetric Filling : The machine dispenses a specific volume of liquid into each container, ensuring consistent fill levels.

Semi-Automatic Operation : Operators manually place containers under the filling nozzles and remove them after filling, making it suitable for lower to medium production volumes.

Piston or Rotary Valve : These components are used to accurately measure the liquid volume before dispensing.

Adjustable Filling Volume : The volume can be adjusted, often by changing the eccentricity of a dosing block or adjusting the stroke of a piston, to accommodate different container sizes and fill requirements.

Reciprocating Nozzle : A reciprocating nozzle can be used to minimize foaming during filling, especially for liquids prone to bubble formation.

Compact and Versatile : These machines are often designed to be compact and adaptable to different container types and sizes.

Material of Construction : They are typically constructed with stainless steel for durability and ease of cleaning, especially important in industries like pharmaceuticals.

Container Placement : The operator manually places the empty containers under the filling nozzles.

Filling : The machine dispenses the pre-set volume of liquid into each container.

Container Removal : Once filled, the operator removes the filled containers.

Optional Features : Some models include features like adjustable bottle support systems and reciprocating nozzles to minimize foaming.

ADVANTAGES

Accurate Filling : Volumetric filling ensures consistent fill levels.

Reduced Labor : Automation of the filling process reduces manual labor.

Flexibility : Can be used with a variety of container types and sizes.

Cost-effective : Semi-automatic machines are often more affordable than fully automatic systems.

DISADVANTAGES

Manual Loading/Unloading : Requires operator intervention for loading and unloading containers.

Slower Production Speed : The manual process can limit production speed compared to fully automatic machines.
