Liquid filling machines, also known as liquid pump filling machines, are devices used to transfer liquids into a container. The machine is filled with the desired product and then sealed. Once sealed, the user can attach it to the designated container and press a button to fill it.
The liquid filling machine was invented in 1887 and it has since undergone many changes, and today there are different types of liquid filling machines available in the market.
1. Piston Filling Machines
Piston filling machines are the most common type of liquid filling machine. They work by using a piston to draw the product from the container and then dispense it into the bottle. The piston is then retracted, and the process is repeated. Piston filler also allows for adjustable speed and volume control.
This type of machine is very accurate and can be used for various products. It is also relatively easy to operate and maintain. The drawback of piston filling machines is that they are not suitable for viscous products or products with particulates as the piston can get clogged.
2. Peristaltic Pump Filling Machines
Peristaltic pump filling machines work by drawing the product from the container and then pumping it into the bottle. The peristaltic pump is a tube that has a series of rollers that compress the tube as it moves. This action creates suction that draws the product into the tube.
The advantage of peristaltic pump filling machines is that they can handle viscous products and products with particulates. The disadvantage of peristaltic pump filling machines is that they are slower than piston filling machines, and they require more maintenance.
3. Gravity Filling Machines
Gravity filling machines work by gravity. The product is gravity fed from the container into the bottle. The advantage of gravity filling machines is that they are very simple to operate and maintain. The disadvantage of gravity filling machines is that they are not accurate and can only be used for low viscosity products.
4. Overflow Filling Machines
Overflow filling machines are the simplest type of liquid filling machines. They work by allowing the product to flow into the bottle until it is full. The advantage of overflow filling machines is that they are very simple to operate and maintain. The disadvantage of overflow filling machines is that they are inaccurate and cannot be used for high viscous products.
5. Time Gravity Filling Machines
Time gravity filling machines are a type of gravity filling machine. They work by allowing the product to flow into the bottle until it is full. The advantage of time gravity filling machines is that they are very accurate and can be used for high viscous products. The disadvantage of time gravity filling machines is that they are slow and require a lot of maintenance.
6. Net Weight Filling Machines
Net weight filling machines are the most accurate type of liquid filling machines. They work by measuring the product’s weight as it is dispensed into the bottle. The advantage of net weight filling machines is that they are very accurate and can be used for high viscosity products.
7. Servo Pump Filling Machines
Servo pump filling machines are the most advanced type of liquid filling machines. They work by using a servo motor to draw the product from the container and then dispense it into the bottle. The servo motor allows for adjustable speed and volume control.
The advantage of servo pump filling machines is that they are very accurate and can be used for various products. The disadvantage of servo pump filling machines is that they are expensive and require a lot of maintenance.
8. Powder Filling Machines
Powder filling machines are a type of liquid filling machine that is used to fill bottles with powder products. The machine works by drawing the product from the container and then pumping it into the bottle. The advantage of powder filling machines is that they are very accurate and can be used for various products.
9. Granule Filling Machines
Granule filling machines are a type of liquid filling machine used to fill bottles with granular products. The machine works by drawing the product from the container and then pumping it into the bottle.
This article has provided you with a brief overview of different liquid filling machines. There are many variables to consider when choosing the right machine, and it is up to you which one best fits your product needs. The type of liquid filling machine that will work for you depends on what kind of product(s) you need to dispense into containers, the speed and accuracy requirements, and your budget.
