INSIDER for Cake and Yeast Raised Donuts

The Insider that makes every kind of donut, cake, yeast-raised, or mini, along with old fashions, twists, fritters and more.

Insider for Cake and Yeast is less common than Insider for Cake and Mini Donuts.  It does everything that the other Insider does, but adds yeast-raised donut capability. The Insider clean-air cabinet is fully self contained and houses a Donut Robot® Mark II or Mark V fryer and Roto-Cooler, plus filtering options and an extra shelf for a Feed Table to insert yeast-raised donuts. For reasons to choose the Insider over stand-alone donut systems, see the tab below marked "Benefits". The Insider is electric only, and not compatible with Mark II Gas fryers. Note that extra space is needed to produce yeast raised donuts, more than the Insider cabinet provides on its own. You will need a table for rolling and cutting donuts, a proofer to allow the yeast to take effect. At full capacity, two people working together are needed, with one person occupied with mixing, rolling, cutting and proofing the yeast-raised donuts.

The Insider has been carefully designed with systems to comply with Safety, Sanitation and Clean-air Ventilation standards. Despite this, it is still wise to obtain early approval from local authorities.

  • What is included with an Insider:

With its ability to produce and sell in any indoor location, the Insider is in a different class to other donut systems!

  • The Insider is on heavy duty casters and can be moved from one place to another. The exhaust hood is built-in and there is no exterior ductwork. You will need 50 Amp electrical service, however.

  • Customers in high traffic areas can watch the Insider frying donuts automatically. 
  • The Insider accepts vehicle-style banner wraps (see photos) to further increase visibility.
  • The Insider eliminates the purchase and installation cost of standard ventilation and fire suppression hoods.
  • The Insider operates in a smaller footprint than other methods of producing and selling.
