Big Dipper Automatic Grease Trap FAQs

(FAQs) Frequently Asked Questions

What make a Big Dipper Automatic Grease Trap different from standard  "grease traps” and "grease interceptors?”

Grease traps and interceptors need to be manually cleaned on a regular basis. Larger units, which are typically installed under the facility floor or outside underground, will require the services of a professional with a vacuum/pump truck.  Smaller, passive traps, which may be integrated into your drain system or in the floor, will require someone to scoop the fats, oils, and grease out of the unit by hand.  A Big Dipper Automatic system cleans itself out on a daily basis with specially designed components, removing fats, grease and oils from the unit and depositing them in an easily emptied container. The Big Dipper does not require manual removal of fats, grease, and oils.

How does the Big Dipper Automatic Grease Trap clean itself?

A Big Dipper traps fats, oils and grease in the unit in baffled chambers and compartments that allow grease to float to the surface of the compartment and water to pass through the unit, in a manner similar to that of a standard grease trap or interceptor. However, a Big Dipper uses a special skimming wheel at regular intervals to skim the floating grease and oils out of the main chamber. These waste products are scrubbed off of the skimming wheel with a wiper blade and then pass out of the unit into an external collection container attached to the exterior of the Big Dipper.

What kind of electrical requirements does a Big Dipper unit require?

Every Big Dipper unit comes standard with an 8-foot cord and a grounded 3-prong plug. The unit plugs into a grounded, 120-Volt outlet for a simple, convenient power connection.

How does the Big Dipper handle the food scraps that go down the drain with the oils and grease?

It depends on the type of Big Dipper unit:

a) In an IS (Internal Strainer) Big Dipper unit, the food scraps are captured in an integrated strainer basket which has to be emptied into a garbage receptacle at least once or twice a day, based on the volume of your foodservice establishment.

b) In an AST (Automatic Solids Transfer) Big Dipper unit, these food scraps are filtered out in an integrated solids chamber and automatically removed to an external container that can be emptied into a garbage receptacle on a regular basis.

What kind of maintenance does a Big Dipper require?

All Big Dipper units need regular cleaning to operate properly.

a) The fat, oil and grease external collection container that is included with the Big Dipper unit is made of translucent plastic, so you can easily monitor and see when the container needs emptying.

b) In all Big Dipper units, the wiper blade and grease trough where the skimming wheel initially deposits the grease should be cleaned at least once a week.

c) The solid food scraps captured in the internal strainer basket included with IS units needs emptying at least once a day.

d) The solid food scrap straining filter in an AST unit should be removed and cleaned weekly.

e) The solids collection container in an AST system should be emptied on a regular basis depending upon the volume of your foodservice establishment.

f) Every 3 months, you may want to shop-vac the internal chambers and rinse out the containers of your Big Dipper to prevent the build up of fine particles.
