Paste Filling Machine
What is a paste filling machine?
One of the types of filling machines is paste filling machine. Paste filling machine is the device used for putting the product inside bottles, jars, tubular containers, or bags. Sometimes such machine is referred to as a viscous liquid filling machine or thick paste filling machine or, more specifically, a piston paste filling machine. The main difference of such machine is its ability to deal with products of high viscosity.
How does a paste filling machine work?
Piston paste filling machines are the most common equipment for paste filling machine.
They operate on a simple principle of intake and discharge cycles
Intake of Product (Suction Stroke):
In this process, the piston is pulled back (moved backward) within the cylinder creating vacuum. This results in suction of the product into the cylinder from the hopper (a large storage tank) or supply tank. The rotary valve or check valve ensures that product is sucked from the hopper into the cylinder.
Discharge of Product (Forward Stroke):
Once the piston is moved forward, it forces the exact amount of the paste out of the cylinder through a filling nozzle into the container beneath it.
Cycling Process:
This process can be adjusted depending on the distance travelled by the piston (the stroke length). Long stroke means larger volume of paste is dispensed in one stroke. This makes it accurate within ±1%.
What are the main types of paste filling machines?
Piston Paste Filling Machine
Most widely used for thick paste. The piston sucks the product into the chamber from the hopper and dispenses it into the container in a predetermined amount.
Pump Paste Filling Machine
Operates with rotary or progressive cavity pump that moves the paste through the pipes and nozzles. Most suitable for high-rate and continuous filling processes.
Auger Screw Paste Filling Machine
Suitable for highly viscous pastes.
In which areas can the paste filling machines be applied?
Food Industry: Thick paste filling machine is suitable for jam, ketchup, sesame paste, sweet bean sauce, honey, peanut butter, salad dressing, cream, chocolate sauce, condiment, etc.
Cosmetic/Daily Chemicals Industry: Automatic paste filling machine is suitable for facial cream, lotion, face cleaner, shampoo/conditioner, toothpaste, lipstick, body cream, sunblock, shower gel, essential oil, etc.
Pharmaceutical Industry: Thick paste filling machine is suitable for cream, ointment, gel, eye ointment, etc.
Chemical Industry: Automatic paste filling machine is suitable for glass adhesive, sealing agent, white adhesive, coating, lubricant, etc.
What are some of the benefits of paste filling machines?
Precision: Thick paste filling machine with high filling accuracy Avoid any giveaways and ensure uniformity in each pack.
Efficiency: Automatic paste filling machine save on labor costs since manual filling takes much longer.
Sanitary: Thick paste filling machine less human contact involved, the lower the chances of contamination.
Flexibility: Automatic paste filling machine have the ability to fill a variety of consistencies.
Material Savings: Thick paste filling machine with anti-drip and suck-back functions prevent wastage of costly material.
Scalability: Begin with manually operated machinery and then progress to automatic paste filling machine.

Frequently Asked Questions
Q1: How does a paste filling machine differ from a liquid filling machine?
A: Thick paste filling machines employ positive displacement through pistons, whereas liquid filling machines utilize gravity, pressure, and overflow.
Q2: Is it possible for a machine to fill thin fluids and thick pastes?
A: There are some machines that can do both thanks to their interchanging components, but a special-purpose thick paste filling works best with high-viscosity products.
Q3: How paste filling machine accurate will the filling process be?
A: Modern-day piston-based paste filling machine are capable of providing ±0.5%-1% precision.
Q4: How should I go about cleaning my thick paste filling machine?
A: Look for units equipped with CIP system and quick-release nozzles.
