Type F-YRD Yeast Raised Donut Depositor

The new method of making yeast-raised donuts that are as delicious as those made by rolling and cutting dough!

With the Type F-YRD, mix dough approximately as usual, then load it directly into the hopper without resting. The depositor drops the donuts onto a screen.

From there, it's as normal - proofing and frying are the same as if you had rolled and cut dough using the normal method for yeast raised donuts.

The finished donuts have an attractive, consistent, well-rounded appearance. They have a distinctive taste, texture and bite that are every bit the equal of other raised donuts. 

  • A mobile table with mounting system is available to securely hold the Type F-YRD while depositing.

The F-YRD extrudes the dough through a donut-shaped opening formed by the plunger.

  • The donut mix recipe is similar to other yeast-raised donut mixes, with some slight differences.
  • Dough is mixed in the usual way, then transferred immediately to the hopper. A roll sheeter is not used.
  • The plunger used is not the same as a cake donut plunger (see photo above).
  • A small amount of 'slurry' is poured into the plunger before depositing begins.
    • The 'slurry' consists of watered down donut mix and is a quick and easy job.
    • This maintains a vacuum in the extruder and makes it easier to extrude the dough.
  • The dough must be manually pushed to the bottom of the hopper. This prevents gaps, and partial deposits.
  • Donuts are deposited onto fryer screens. Each donut needs room to expand.
  • Proofing is normal, usually 35-45 minutes.
  • Frying is normal.
  • Deposit size can be adjusted.
  • Maximum finished donut size is 3¾-4 inch (95-102 mm), dependent on ingredients used.
  • For ring donuts only.
  • Type F-YRD can be used with Donut Robots® using Trays and Cloths, instead of Screens.

Donuts created by the Type F-YRD show subtle differences to other yeast raised donuts.

These are general observations from a consumer perspective.

  • Donuts are more consistently well-rounded than other yeast raised donuts.
  • Donuts present a slightly less 'puffy' appearance.
  • Donuts have a pleasing, slightly 'chewy' bite and texture.
  • When broken in half and examined, Donuts have an even, consistent cell structure.
  • Donuts can be glazed, iced and sugared as normal.
