Food Oil Intermediate Filters

Mott food oil intermediate filters excel at removing catalyst, bleaching agents, solidified product, and other solid contaminants from a variety of alcohol, acid, or oil-based processes. Whether it’s palladium-on-carbon catalyst from a hydrogenated oil stream or bleaching agents from edible oil or detergent precursors, the Mott LSI filter is ideal for automated, closed-loop operation with clean-in-place backwashing for food oil intermediate filtering needs. Generally done without the need for additional filter aids, the Mott LSI can filter streams with catalyst less than 1 micron in size and with solids loading up to 5+ wt.%. The backwash system for these food oil intermediate filters can be designed to discharge between an approximate 15 wt.% slurry to an approximate 50 wt.% wet cake, providing efficient and effective filtration for intermediate stages in food and oil processing.

Mott LSI filters for catalyst processes are designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas assisted pulse or through a backwash cycle.

Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you have a spare set of filter elements to continue operations while elements are being cleaned.

The Mott Filter Design Process

  1. Filter Feasibility Testing – In our Customer Innovation Center, we will replicate, or very closely correlate, your process conditions to determine the appropriate media grade and material for your application, including food oil intermediate filters. We will provide you with a comprehensive, in-depth analysis to prove the feasibility of using porous metal for food oil intermediate filtration in your process and furnish you with a comprehensive ROI justification.
  2. Pilot Testing – As an option, we can install a pilot unit in your facility enabling you to witness, first-hand, how our food oil intermediate filters will perform in your process stream and under your actual operating temperatures and pressure conditions.
  3. Front-End Engineering Design – Our Front-End Engineering Design (FEED) process provides you with a complete process engineering package for food oil intermediate filters, including vessel drawings, a preliminary equipment layout drawing, piping and instrumentation diagram, process flow diagram, valve and instrument list, and a detailed process functional description.
  4. Fabrication – When it comes to fabricating your system, we can handle as much or as little as you need – from fabricating only the filter vessel to providing a complete turnkey skid system designed for food oil intermediate filtration.
  5. Operational Support – When your filtration system, including food oil intermediate filters, is complete, our professionals can provide equipment commissioning and startup services, training, ongoing technical support, and quality assurance testing for the life of your system.

Depending on your needs, Mott can provide just the filter elements, a vessel and elements, or provide you a full turnkey system with the vessel, frame, piping, instruments, and controls tailored for food oil intermediate filtration.
