Consultation, Design, and Installation of Used Cooking Oil Filtration Systems

The food processing process leads to the degradation of cooking oil, which reduces its lifespan, diminishes the sensory qualities and flavor of the food, and negatively impacts consumer health.

Therefore, frying oil filtration and treatment systems are increasingly being considered and favored. Among these, systems using plate and frame filter equipment are prioritized in the food industry due to their efficiency and simplicity.

Understanding these customer needs, INGREDA provides frying oil and cooking oil filtration solutions based on advanced technology from the USA, Germany, and India.

An Overview of Frying Oil Filtration Technology Using Plate and Frame Filters

During food processing, the oil used for frying is affected by many factors. This leads to oil degradation, negatively impacting not only the quality of the food but also the cost of proper treatment.

To learn more about these influencing factors, please read our articles “Enemies of Frying Oil and How to Defeat Them” and “Polar Compounds Formed During Frying and Their Effects.”

Why Are Plate and Frame Filters Preferred?

Plate and frame filters are a type of pressure filtration equipment. In practice, they are often used for solid-liquid separation with many advantages such as simple design, high efficiency, low maintenance when operated correctly, and easy upgrading and capacity expansion when necessary. The machine can operate continuously or in batches.

In industrial production, plate and frame filters are used to remove impurities in various sectors, including oil and gas, chemical-textile dyeing, metallurgy, pharmaceuticals, food processing, paper production, refining and treating used cooking oil, and wastewater treatment.

Principle of Frying Oil Filtration Using Plate and Frame Filter Systems

Our frying oil filtration system is simple and consists of the following basic steps:

  • The frying oil from the food processing stages is added to the mixing tank system. Here, selected oil filtration powders are added to the tank along with the oil, based on the processing objectives. The mixing blades ensure uniform agitation. These filtration powders meet various customer needs, such as reducing fatty acid levels, decreasing color, and minimizing odor.
  • After a period of stirring in the tank (at a specified temperature, speed, and time), the oil and powder suspension is circulated through a plate filter press.
  • Here, the frame serves as a container for the filter cake and is where the suspension enters. The filter cloth creates a filtering surface with grooves for the filtered oil. The filtered oil flows out through the piping system and into the filtered oil tank (the oil can be used in food processing). The filter cake is retained in the frame.
  • When the frame is full of filter cake, the filtration process is stopped to proceed with washing and removing the filter cake.
