What are the classifications of filling machines
Classified by material：
Liquid filling machine: there are magnetic pump filling machine, self-flow filling machine, servo piston filling machine and negative pressure filling machine, etc., which are specially suitable for various types of liquids. For example, the viscosity same as water, or the viscosity same as cream.
In addition, liquid filling are divided into the following categories according to different filling methods
Atmospheric filling machine: A machine that fills liquids into packaging containers under normal pressure. Suitable for filling liquid products with low viscosity and no gas, such as white wine, vinegar, soy sauce, milk, syrup, etc.
Negative pressure filling machine: a machine that first evacuates the packaging container to form a negative pressure, and then fills the liquid into the packaging container. It is suitable for filling low-viscosity liquid materials, such as oils, syrups, vitamin-containing beverages, pesticides, and chemical reagents. But it is not suitable for filling aromatic wines, because it will increase the loss of wine aroma.
Isobaric filling machine: A machine that first inflates the packaging container so that its internal gas pressure is equal to the gas pressure in the liquid storage tank, and then fills the packaging container with liquid. It is suitable for filling gas-containing beverages such as beer, soda, etc., which can reduce the loss of carbon dioxide gas contained therein.
Pressure filling machine: A machine that uses external mechanical pressure to fill liquid products into packaging containers. Suitable for filling viscous materials, such as tomato sauce, minced meat, toothpaste, balsam, etc.
Powder filling machine: single-head powder filling machine, double-head powder filling machine, suitable for various types of powder packaging. Generally for products with high accuracy requirements, such as milk powder, protein powder, etc., will choose to use double-head Powder filling machine, secondary metering and blanking, accuracy can reach 0.5%
Granule filling machine: 2-head or 4-head linear scale filling machine, 10-head or 14-head combined scale filling machine, according to the speed requirements and accuracy of the product, choose different weighing scales.
Classified by the main form of movement of the packaging container
Rotary filling machine: After the packaging container enters the filling station, it is driven by the filling machine turntable to rotate around the main vertical axis, and completes continuous filling by turning for nearly one circle, and then the turntable is sent to the capping machine for capping. This type of filling machine is widely used in the food and beverage industries, such as the filling of soda, juice, beer, and milk. This machine is mainly composed of feeding system, bottle feeding system, filling valve, large turntable, transmission system, body, automatic Control and other parts. The filling valve is the key to ensure that the filling machine can work normally.
Linear filling machine: The packaging container moves along a straight straight line and is filled in rows when it is stopped. As shown in the figure on the right, this type of filling machine has a relatively simple structure and is convenient to manufacture
Classified by degree of automation
Manual filling: the filling process is all controlled by manual operation
Semi-automatic filling machine: In liquid filling, bottle loading and unloading are all operated manually, but the filling process is automatic.
Automatic filling machine: This type can be divided into stand-alone automatic machine and combined automatic machine (which can include continuous bottle washing, filling, capping, labeling, boxing and other processes). Among them, the combined automatic machine is suitable for the filling production line of large and medium-sized factories
