How to choose the right filling machine?

Buying a filling machine is a complicated process, and because there are so many options for filling machines, it can be difficult to know which one is better for your product. The following are the questions you need to know before purchasing a filling machine, hoping to help you choose the equipment that best suits your production needs.

What do I need to fill when buying a filling machine?

While some bottle filling machines are designed to fill dry goods such as powders or pills into containers, there are others suitable for handling liquids. If you are considering purchasing a filling machine, the first important factor to consider is the viscosity or consistency of the product. The viscosity of the product will help determine which type of filling technique the machine uses to properly handle the specific properties of the product. If the product has a high viscosity (such as molasses), consider purchasing a filling machine that can handle the physical properties of the product.

The principle of back pressure canning machine

Carbonated beverages (such as beer, soda, champagne, etc.) require unique filling technologies and specialized filling equipment. If you need to consider purchasing a filling machine that can properly fill/bottrate carbonated products, this type of machine is called a back pressure filling machine.

Backpressure fillers keep the liquid carbonated even during bottling through a process of double pre-evacuation. This method works by pulling air from a bottle and pressurizing it with carbon dioxide. Then, by repeating this process, make sure that 99.99% of the oxygen in the bottle can be removed (double pre-vacuum). Due to these repeated pre-evacuation cycles, bottled carbonated products have a longer shelf life.

Standard for the degree of automation of filling machines

When purchasing a filling machine, it is critical to determine which level of automation to use. Manual fillers are a great option for home brewing, entry-level brewing, or small companies with few employees and no plans for growth. Manual fillers are designed to handle relatively low volumes and are therefore not suitable for small to medium breweries or breweries with expansion plans.

Semi-automatic fillers are a good "in-between" option for most small breweries and ideal for breweries with growth plans. These machines are more productive than manual filling machines, but still require some manual work, which reduces filling efficiency. In terms of price, semi-automatic filling machines are between manual filling machines and automatic filling machines and are an economical investment.

The automatic filling machine is the best choice for large breweries (large enterprises with higher production volume) because the filling speed of this machine is much faster than that of manual filling machines and semi-automatic filling machines. Although automatic filling machines take up a lot of space, they rarely require manual handling. Automatic filling machines are usually the most expensive in terms of purchase and maintenance.

How much volume does the filling machine need to fill

The size and capacity of the container can have a huge impact on weight changes during filling. Due to the properties of some liquids, it may be necessary to fill the container, so set the fill volume. This can effectively and accurately control product waste.

Maintenance and cleaning of filling machines

Liquid build-up in components can affect the normal operation of the filling machine and the quality of the finished product. Try to choose machines that are easy to clean and maintain to prevent contamination and poor product quality.
