What Is Filling Machinery?
Filling machinery automates the process of filling containers like bottles, cans, and tubes with products such as liquids or powders. This machinery enhances production capacity, and accuracy, and reduces labor costs.
There are two main types: semi-automatic machines that require operator input to fill a set amount and fully automatic machines that handle the entire process from filling to capping and labeling.
Applications of Filling Machinery
These machines are pivotal in automating production processes across various industries, including food, cosmetics, and daily essentials. They increase production speed, improve work accuracy, and enable precise reproducibility through computer management.
While the most common type fills a predetermined amount into continuously supplied containers, specialized machines exist for products requiring multiple contents, such as cosmetics.
Principle of Filling Machinery
Gravimetric filling, using a load cell for weight measurement, is standard for liquids and powders, ensuring consistent fill volumes and facilitating next steps like capping. Special considerations are made for material adhesion and scattering.
1. Liquid Filling Machinery
These machines may also use level sensors for filling, balancing accuracy with visual fill level alignment.
2. Powder Filling Machinery
Powder fillers often incorporate augers to manage the material flow and measure fill amounts accurately, preventing spillage.
Types of Filling Machinery
Divided into liquid and powder filling machines, each type caters to specific industry needs, from food to chemicals and pharmaceuticals, accommodating various container shapes and materials.
1. Liquid Filling Machinery
These machines vary to handle different volumes and viscosities, from water-like to highly viscous substances, ensuring compatibility with all container types.
2. Powder Filling Machinery
Designed for materials with low fluidity, auger fillers improve material discharge and fluidity, allowing for accurate, high-speed filling.
Choosing Filling Machinery
How to Choose Filling Machinery
There are many types of filling machinery, so you need to consider the advantages and disadvantages when choosing one.
1. Screw-Type Filling Machinery
This is a powder filling machinery that sends out and weighs powder.
2. Vibratory Feeder Filling Machinery
This method transfers the filling by vibrating the solid material.
3. Tube Pump Filling Machinery
This is a liquid filling machinery that sucks up the filling material from a tube, transfers it with a pump, and fills it while measuring it with a weighing machine.
4. Rotary Filling Machinery
This is a machine that can fill viscous materials by placing two rotors in the pump chamber and sending out fluids by changing volume.
5. Piston Type Filling Machinery
This is a filling machinery that sucks in the filling and spits it out like a large syringe.
