How To Choose Suitable Components For Fluid Packaging Equipment?

The core principle in selecting components for fluid packaging equipment is precise matching based on the physical and chemical properties of the material to ensure the stability, safety, and efficiency of the packaging process. Below are selection recommendations for key components based on different material characteristics:

 

Selecting Metering Pumps and Piping Systems by Viscosity

Low-viscosity liquids (e.g., water, juice, alcohol): Peristaltic pumps or plunger pumps are suitable due to their simple structure, easy cleaning, and high metering accuracy.

Medium-to-high viscosity fluids (e.g., sauces, shampoo, honey): Screw pumps or gear pumps are recommended for stable delivery of thick materials and to prevent bubble formation.

Semi-fluids containing particles (e.g., jams with pulp, seasonings with residue): Rotary pumps or screw pumps with agitation functions should be used to prevent clogging and maintain material uniformity.

 

Selecting Contact Materials Based on Corrosiveness/Chemical Properties

Acidic or alkaline materials (e.g., vinegar, cleaning agents): All contact parts should be made of 316L stainless steel, providing stronger corrosion resistance and extending equipment life.

Oil-based or organic solvent-based materials: Teflon-coated piping or food-grade oil-resistant rubber seals are required to prevent swelling and aging.

 

Configuring Temperature Control and Insulation Systems Based on Temperature Sensitivity

For heat-sensitive materials (e.g., dairy products, enzyme preparations): It is recommended to install a jacketed insulation layer or a cooling circulation system to control temperature fluctuations during filling and prevent deterioration.

 

Optimizing the Feeding Structure Based on Gas Content and Foaming Tendency

For easily foaming materials (e.g., beer, foaming daily chemical products): Defoaming devices and flow stabilizing buffer tanks are required. Low-shear pumps should be used to reduce turbulence and ensure filling accuracy.

 

Upgrade System Design to Hygiene Standards
For the food and pharmaceutical industries: A fully enclosed aseptic filling system must be selected, supporting CIP/SIP cleaning, with all seams smooth and without dead corners, and conforming to GMP and HACCP standards.
