Hot Oil Filtration

Clean Oil & Dry Filtered Crumbs


1 Micron Filtration for Industrial Fryer Oil Systems 

The Oberlin Hot Oil Filter is the top-performing filter for fryers and roasters and is used by the world’s largest food manufacturers. The filter’s ability to remove 1 micron particles keeps frying oil in good condition indefinitely. The filter’s ability to discharge dry crumbs minimizes oil carryout.


The Oberlin Filter is a fully automatic pressure filter. The dirty frying oil is pumped into the filter where disposable, non-woven filter media and the previously collected solids remove nearly all sediment (crumbs, flour, spices, etc.) larger than 1 micron. The sediment is removed before it can burn or scorch the hot oil, thus extending its life.


The completely automatic Oberlin Filter is offered in multiple sizes and system configurations. The Oberlin Filter can be used for


  • Continuous filtration of a single hot oil fryer or roaster to remove crumbs

  • Continuous filtration of a single hot oil fryer or roaster to remove crumbs and Free Fatty Acids – FFA’s

  • Batch filtration of multiple hot oil fryer or roasters to remove crumbs and FFA’s


No matter what filter size or system configuration selected, the Oberlin Filter will remove nearly all particles larger than 1 micron in size along with FFA’s and discharge them as a dry cake.

Oberlin Filter Hot Oil Filtration Overview

Benefits of 1 Micron Filtration Provided by the Oberlin Hot Oil Filter

Reduction and/or Removal of Total Polar Compounds (TPC’s) and Free Fatty Acids (FFA’s)
  • 1 micron filtration slows or eliminates the breakdown of the oil.

  • Growth of Total Polar Compounds (TPC’s) and Free Fatty Acids (FFA’s) due to burning solids are eliminated.

  • When combined with oil carryout in the product, TPC/FFA growth is delayed or eliminated.

  • Maintain FFA’s below 0.10% continuously with the Oberlin Filter Continuous Treatment System (CTS) and FFA absorbent!

  • With a batch treatment system and FFA absorbent, the Oberlin Filter can recover oils with up to 0.9% FFA’s!

Eliminate Flavors and Spices in the Industrial Oil Filtration Process

The Oberlin Hot Oil Filter removes flavors from the hot oil allowing for spicy products to be run anytime during the week. You won’t have to dump your hot oil after the spicy run and your production schedule is more efficient and flexible.  

Reducing Dark Spots and Maintaining Perfect Hot Oil Color

Dark-colored oil is the result of burning solids and this affects the color and quality of the fried product. Effective sediment removal with the Oberlin Hot Oil Filter eliminates the dark color and formation of ‘black spots’ on the product. The continual supply of clean oil from the filter will maintain a consistent color from morning to night.  


Smoking/Scorching and off-flavors will never be an issue with an Oberlin Filter!

With an Oberlin Filter you will be able to continually recycle and reuse your oil!

One of the world’s top food manufacturers declared a $1.2 MILLION annual savings in recovered oil with the Oberlin Filter!


*Based upon 100 lbs/hour of dropped crumb

**Based upon $0.75/lb oil cost

***Based upon 20 hours/day, 350 days/year

Completely Automatic Dry Solids Discharge from the Oberlin Hot Oil Filter

Filtered crumbs, solids and fines are automatically discharged in a dry cake

The filter is self-cleaning. There is no operator intervention or offline time to remove crumbs, solids, or fines from the filter. They are discharged automatically after they are collected and dried. The oil removed from the crumb goes back to the fryer, thereby minimizing hot oil costs. The dry cake is environmentally friendly and is easily disposed of. The reclaimed hot oil savings is significant and often pays for the cost of the filter within the first 6-12 months. Those savings are realized annually throughout the life of the filter.

Dry Cake & Hot Oil Savings Comparison (Oberlin, Gravity, Vacuum)

Cake dryness for gravity or drum filters is typically 40%, for vacuum filters 60%-65%, and for the Oberlin Filter 75%-80%. The Oberlin Filter reclaims much of the hot oil that would be lost in the discharge of these other filters. The savings are significant. 

Below is a chart that shows the amount and value of the recovered oil that an Oberlin Filter provides by having an ultra dry crumb.  The numbers are based on 100 lbs/hour of crumb discharged by the 3 different filter types operating 20 hours/day, 350 days/year.  The dollar savings is based on oil that costs $0.75/lb.

More Oberlin Filter Benefits 

More Oil Choices with Extended Oil Life
Change oil type to a less expensive, less stable oil

With the extended oil life provided by the Oberlin Filter, you have more oil choices. You are not locked into an oil type solely based upon price and/or stability.  Our customers have the choice to change the type of oil (Palm, Corn) to a less expensive oil (Soy, Cottonseed) because the Oberlin Filter will extend the life of the less expensive oil.


Cleaner Fryer 
More Uptime with Efficient Removal of Coatings and FFA’s

With the cleaner, more consistent oil provided by the Oberlin Filter the time between fryer/roaster cleaning can be extended and the amount of time required to clean the fryer will be reduced. A gain of only one hour per day is a gain of over 300 hours per year!

Benefits of Reducing the Frequency of Cleaning/Boil-outs

  • Sanitation Savings (less boil-outs, less hours)

  • Chemical Savings (less caustic cleaning solutions)

    • One of our large food manufacturing clients saves over $20,000/year

  • Production savings

    • Another client gained an extra hour of production before they shut down every day. (Gained 260 production hours)

  • Energy Savings (Less solids, more efficient heating)

Self Cleaning

The Oberlin Filter has a Clean in Place(CIP) mode that is an automatic sanitation feature that allows you to run any cleaning solution through the filter after it has gone through your fryer or roaster.  An operator is not needed to clean out the inside of the fryer, the filter does it all automatically.  


Lower Energy Costs

Heat transfer efficiency is increased with clean oil as maintained by the Oberlin Filter. Heat exchanger plugging and heating coil fouling are reduced or eliminated with clean oil, thereby reducing energy costs.


High Volume Filtration for Online or Offline Batch Treatment
  • With the Oberlin Filter’s continuous treatment system the oil will be clean and a consistent quality throughout your production, from start to finish. 

  • The Oberlin Filter operating during production can filter 20-50 gallons a minute. On average 35 gallons a minute with a one turn over an hour for a fryer.

  • Batch treatment for filtration on an as needed basis with filtration rates of 330 gallons per hour.


Your Performance Benefits Highlights

• Fast return on investment – in many cases less than one year

• Considerable oil savings by reducing waste oil discarded with filter’s sediment

• Production savings due to longer oil life, fewer shut downs for oil changing and faster cleaning

• Environmental and cost savings thanks to fewer caustic chemical cleaning solutions and less water

• Tighter control over end product quality

Edible Oils


Oberlin Filter Company has developed a version of the Automatic Pressure Filter for filtering edible oils such as Flax and Hemp Oils. By using 1 micron medias we are able to provide excellent clarity and remove sediment without removing desirable ingredients or using filter aids.


This version of the filter is completely stainless steel with the wetted parts polished to a sanitary finish. It is capable of being cleaned in place.
