Liquid filling machine can be divided into normal pressure filling machine, pressure filling machine and vacuum filling machine for ideal filling equipment for medicine, daily chemical, food, pesticide and special industries according to the filling principle. The working principle and structural characteristics of the liquid filling machine: The machine is reasonable in design, compact in size and convenient in operation. The pneumatic parts are made of pneumatic components of Germany FESTO and Japan SMC; the piston and cylinder of the cylinder are made of PTFE and stainless steel. Made, in line with GMP requirements; filling volume and filling speed can be adjusted arbitrarily, high precision; filling bulkhead adopts anti-drip, anti-drawing and lifting filling device; this machine can be modified into multi-head, explosion-proof according to customer needs , overflow filling system.
1. The atmospheric pressure filling machine is filled by liquid weight under atmospheric pressure. This type of filling machine is divided into two types: timed filling and constant filling. It is only suitable for filling low viscosity gas-free liquids such as milk and wine.
Second, the pressure filling machine is filled under atmospheric pressure, and can also be divided into two types:
(1) The pressure in the liquid storage tank is equal to the pressure in the bottle, and is filled by the liquid self-weight flowing into the bottle, which is called isostatic filling;
(2) The pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle by the pressure difference, and the high-speed production line mostly adopts this method. The pressure filling machine is suitable for liquid filling with gas, such as beer, soda, champagne and so on.
Third, the vacuum filling machine is to fill the pressure in the bottle below atmospheric pressure
(1) There are many types of packaging machines, and there are many classification methods. There are a variety of different viewpoints, depending on the product status, there are liquid, block, and granular packaging machines;
(2) Liquid packaging machines, ie packaging equipment for packaging liquid products, such as beverage filling machines, dairy filling machines, viscous liquid food packaging machines, liquid cleaning products and personal care packaging machines, etc. are all categories of liquid packaging machines. . Due to the wide variety of liquid products, liquid product packaging machines also have many types and forms. Among them, the liquid packaging machine used for packaging liquid foods has higher technical requirements. Aseptic, hygienic and safe are the basic requirements of liquid food packaging machines. .
