Hand sanitizer filling machines are classified according to the principle of canning

Common hand sanitizer filling machines are liquid filling machines. According to the filling principle, liquid filling machines can be divided into atmospheric filling machines, pressure filling machines and vacuum filling machines. Atmospheric filling machine is filled by the weight of liquid under atmospheric pressure. This type of filling machine is divided into two types: regular filling and constant volume filling. It is only suitable for filling low-viscosity airless liquids such as milk and wine. The filling of the pressure filling machine is carried out at a pressure higher than atmospheric pressure, and it can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight, which is called etc. Pressure filling; the other is that the pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle by pressure difference, which is often used in high-speed production lines. The pressure filling machine is suitable for filling gas-containing liquids, such as beer, soda, champagne, etc. The filling of the vacuum filling machine is carried out when the pressure in the bottle is lower than the atmospheric pressure. The filling machine is simple in structure, high in efficiency, and has a wide range of viscosity for oil, syrup, fruit wine and other materials. The oil injection machine can fill various oil products, such as edible oil, lubricating oil, peanut oil, soybean oil, etc. This kind of filling machine is specially developed for filling oil products, and can realize the flexible configuration of manual operation and unmanned operation. Stopper filling machine This type of filling machine is widely used in special industries such as medicine, food, daily chemicals, grease, pesticides, etc. It can fill various liquids and paste products, such as disinfectants, hand sanitizers, toothpastes, ointments, and various cosmetic. The sauce filling machine is suitable for thick sauces filled with particles in seasonings, such as chili sauce, bean paste, peanut butter, sesame paste, jam, butter hot pot base, red oil hot pot base. According to the operation process, it can be divided into automatic filling machine and semi-automatic filling machine
