Filling machine and packaging machine, I believe everyone will be vague, now I will introduce you clearly. There are many kinds of filling machines, which can be divided into normal pressure filling machines, pressure filling machines and vacuum filling machines according to the filling principle. These three filling machines are widely used. For example, the atmospheric pressure filling machine uses the self-weight of liquid at atmospheric pressure to fill, the pressure filling machine fills at a pressure higher than atmospheric pressure, and the vacuum filling machine fills at a pressure lower than atmospheric pressure in the bottle. The functions of the three are different. The atmospheric filling machine can be divided into two types: regular filling and constant volume filling, which are only suitable for filling low-viscosity airless liquids such as milk and alcohol. Pressure filling machines can also be divided into two types: one is equal pressure filling, and the other is that the pressure in the liquid storage tank is higher than that in the bottle, and the liquid flows into the bottle by pressure difference. This method is mostly used in high-speed production lines and for filling liquids containing gas, such as beer, soda and champagne. The vacuum filling machine has simple structure, high efficiency and wide adaptability to the viscosity of oil, syrup, fruit wine and other materials.
This packaging machine is mainly used for automatic packaging of fluid and semi-fluid products such as fruit juice, jam, honey, ketchup, shampoo, liquid, pesticide particles, food, electronic components, etc. Its process parts are made of stainless steel, which can well ensure the hygiene and safety of products.
Secondly, the principles and characteristics are different. The filling machine has simple operation process and small precision error, and is very convenient in installation and adjustment, equipment cleaning and maintenance. Some machines adopt drip-proof wire drawing filling plug, anti-foaming product filling lifting system, positioning system to ensure bottle mouth positioning and liquid level control system. Packaging machines are generally made of stainless steel, equipped with high-position balancing tank or self-priming pump for quantitative filling and direct heat sealing and cutting. The adjustment of bag size, packaging weight and sealing and cutting temperature is convenient and reliable.
From this, we can easily see the difference between filling machine and packaging machine. It's not just the principle, characteristics, uses, etc … so when buying, you must choose the products and equipment suitable for your own enterprise.
