Krispy Kreme’s Company Facts
 The very first Krispy Kreme was
established in Winston Salem,
North Carolina, in July 13, 1937.
 The founder, Vernon Rudolph,
whom originally set up a doughnut
distribution factory without a
storefront, but customers kept
dropping by asking for hot
doughnuts.
 ..so he built a window into the
factory wall and started selling
doughnuts fresh off the line.
Krispy Kreme Go Global
 In December 2001, The First International
Store opened in Canada just outside of
Toronto.
 In November 30, 2006, The First Krispy
Kreme Store in The Philippines opened,
located at The Bonifacio High Street in Fort
Bonifacio Taguig City.
 Metro Manila – 29
 North Luzon – 3
 Southern Luzon – 4
 Visayas – 3
 Mindanao – 5
Krispy Kreme’s Raw Materials
The “SECRET YEAST-RAISED
DOUGHNUT RECIPE” from a New
Orleans French Chef:
 Krispy Kreme doughnut mix
 Water
 Yeast
 Sugar
 Doughnut Filling
 Other packed ingredients
How Krispy Kreme’s Work
 Mixing –
A batch of “Original Glazed” starts with
Krispy Kreme doughnut mix, water and
yeast, (the same single-cell fungi used to
make bread rise).
The yeast is what makes the “original
glazed” so light – it puffs the dough up
with air, so it’s not dense like a cake
doughnut.
The Bakers mix the ingredients to form a
dough, which they pour into a hopper.
How Krispy Kreme’s Work
 Extruding –
The Hopper feeds into an extruder, the device that
forms the dough rings that eventually become
doughnuts.
The extruder machine uses pressurized air to force
dough through a ring-shaped cutter – a cylindrical
cutter around another round cutter.
Since the cutter forms doughnuts in the shape of a
ring, there is never a really cut-hole in Krispy
Kreme doughnuts.
The extruder deposits the ring-shaped dough
directly onto a rack conveyer belt that takes the
doughnut to its next stop, proof box.
How Krispy Kreme’s Work
 The Proof Box –
The proof box, or proofer, is a tall glass
case that houses a doughnut conveyer
belt.
The conveyer belt carries doughnut
trays slowly up and down in a zigzag
motion all the way through the proof
box.
The purpose of the proof box is to
surround the doughnuts with heat and
humidity.
How Krispy Kreme’s Work
 The Proof Box –
Humidity and low heat make the
yeast organisms more active w/o
killing them.
When the yeast becomes active, it
eats sugar and releases carbon dioxide
gas as a waste product.
The carbon dioxide expands, creating
air pockets all through the dough.
How Krispy Kreme’s Work
 The Proof Box –
In order to heat the doughnuts to
just the right temperature, the
proof box machine has to keep
the heat and humidity at very
specific levels for a certain
amount of time.
If it gets too hot or humid, the
machine opens up vents in the
side of the proofer to let some air
out.
How Krispy Kreme’s Work
 The Proof Box –
The dough spends 15 to 20 minutes
in the proof box. Although, Krispy
Kreme doesn’t publicize the “exact”
proofer settings, as they are part of
the “secret” recipe.
As the conveyer belt carries the
dough through the proof box, the
yeast transforms the dough from a
thin ring to a full size, puffed
doughnut. When the doughnut is
fully expanded, it is ready be cooked.
How Krispy Kreme’s Work
 Frying –
The conveyer belt tips each
doughnut tray over at the end
of the proofer run, dropping the
doughnuts onto another
conveyer belt that takes them
through the rest of the
preparation process.
The second conveyer belt and
the proofer belt are connected
by a gear train so they’ll always
move in unison.
How Krispy Kreme’s Work
 Frying –
The conveyer belt carries the
doughnuts through a vegetable oil
bath heated to between 335 and
360 degrees Fahrenheit (about
180 degrees Celsius).
How Krispy Kreme’s Work
 Frying –
The doughnuts actually
float in the bath as they’re
pushed along by the bars
connected to the belt.
Since the doughnuts are
floating, the bath only
cooks one side at a time.
 Frying –
After the first side cooks, the
doughnuts pass over a rotating arm
that lifts them up and tips over.
The doughnuts have to be cooked to
85 to 87 degrees Fahrenheit (about
30 degrees Celsius), which takes
about 45 seconds for each side.
The bakers have to fry the
doughnuts for a very specific
amount of time in order to ensure
the right taste and texture.
How Krispy Kreme’s Work
How Krispy Kreme’s Work
 Frying–
o At several points during the day,
the manager will actually time
and check the process to make
sure the doughnuts are cooking
just right.
o After they are cooked, the
conveyer pushes the doughnuts
out of the oil onto the cooling belt.
How Krispy Kreme’s Work
 The Cooling Belt–
The cooling belt is one way to get rid
of the excess oil / fat / grease in the
fried doughnut.
After cooling it down for a while.
Bakers prepare the glaze in a large
mixing container and then pump it
out to the glazing waterfall reservoir.
How Krispy Kreme’s Work
 The Glazing–
The glaze is a mixture of sugar, milk
and other ingredients.
Another pump draws glaze up from
the reservoir to the top of the
waterfall, where it falls down over
the doughnuts on the conveyer belt.
As each doughnut passes through
the waterfall, it’s completely coated
in glaze.
How Krispy Kreme’s Work
 The Glazing
and Cooling–
The rest of the
doughnuts, marked
for delivery, stay on
the conveyer belt.
The belt takes them
up a ramp and all
the way around the
factory room.
How Krispy Kreme’s Work
 The Glazing and Cooling–
The long, slow ride (it lasts about
40 minutes) gives the doughnuts
plenty of time to cool before
they’re packed in boxes and on
trays for delivery.
This is an important step in the
process – packing hot doughnuts
immediately would simply be too
messy.
How Krispy Kreme’s Work
 Customizations–
Right at the end of the line, the doughnuts pass
through the chocolate icer, which the bakers uses
to make chocolate-covered doughnuts.
The icer is sort of like the glaze waterfall, but it
coats the doughnut with chocolate.
After the icer, the doughnuts pass through the
cooling tunnel, a refrigerated, enclosed area where
the chocolate hardens rapidly.
The machine-iced doughnuts are for delivery
shipments while the hand-dips doughnuts are sold
in the stores.
 Customizations–
Other outlet stores of
Krispy Kreme in the
United States of America
offers different varieties
of cake-fried-doughnut
filled with different jam-
fillings.
The two nozzle heads
pumped out the exact
amount of filling for each
doughnut.
How Krispy Kreme’s Work
 Packaging and Deliveries–
After the glazing and cooling
tunnel, the doughnuts are ready to
go.
Packers load them in boxes and on
trays, and then stack them onto
carts.
How Krispy Kreme’s Work
How Krispy Kreme’s Work
 Packaging and Deliveries–
When it’s time to run the route,
employees roll the carts onto the
delivery trucks.
At Raleigh Factory Store, the
delivery drivers run 14 different
routes, serving about 26 merchants
each day.
SNACK STATS:
Krispy Kreme reports these statistics on its Website:
Every DAY, Krispy Kreme makes about 5 million doughnuts.
Every YEAR, they make about 2 billion doughnuts.
Every WEEK, they make enough doughnuts to reach from New York to Los Angeles.
Every YEAR, they use up two Olympic-sized swimming pools worth of chocolate.
Every YEAR, they use about 1 million pounds of sprinkles.
Collectively, Krispy Kreme’s stores could make a doughnut stack as high as the
Empire State Building. (that’s 1,454 feet or 443 meters) in only two minutes.
Doughnuts and Coffee since 1937
Our mission is to touch and enhance lives through the joy that is Krispy Kreme.Our mission is to touch and enhance lives through the joy that is Krispy Kreme.
Our vision is to be the worldwide leader in sharing delicious tastes and creating

We Believe...We Believe...
Consumers are our lifeblood, the center of the doughnut
There is no substitute for quality in our service to consumers
Impeccable presentation is critical wherever Krispy Kreme is sold
We must produce a collaborative team effort that is unexcelled
We must cast the best possible image in all that we do
We must never settle for "second best;" we deliver on our commitments
We must coach our team to ever-better results.
