- The waffle started out in the Middle Ages as a flat wafer made not from wheat flour, but from oats or barley.
- As its popularity spread, many variations of shape and recipe developed.
- The introduction of leavening ingredients gave rise to the waffle as we know it today.
- It's enjoyed across Europe as a type of cake,
- but in America they have them for breakfast.
- The introduction of frozen waffles in the 1950s
- marked the dawn of a new era for those that liked eating them, but not cooking them.
- Knocking up a plate of waffles was suddenly a snap.
- All the main preparation work takes place at the factory.
- They add flavourings like berries to a flour-based waffle mix
- and then turn to liquid ingredients.
- Water, canola oil and liquid cane sugar.
- They pour them into a big tank and mix thoroughly.
- They're then ready to thicken it into a batter with the flour-based waffle pre-mix.
- It also includes baking powder,
- which reacts with water to cause pockets of carbon dioxide to form
- for a leavening effect that will continue during baking.
- After adding more berries, this batter is complete
- and there's enough in this one tank to produce 3,600 waffles.
- Hot waffle irons are sprayed with a mist of non-stick coating.
- Down the line, an automated pump deposits measured amounts of batter onto each grid plate.
- The top grid plates encase the batter.
- This production line is computerized,
- which ensures the plates are filled quickly and without any spills.
- As they move towards the oven, the waffle irons rotate,
- allowing the batter to reach all the crevices inside.
- They now move through a long gas oven.
- It takes about two minutes for them to cook.
- They emerge from the oven piping hot,
- where a machine called a picking drum removes them from the irons.
- As the picking drum revolves, needles grab the waffles and pull them off the hot grid plates.
- The picking drum transports the waffles up to another level.
- The needles retract, transferring them to a series of conveyors.
- At the other side of the factory, the waffles enter a blast freezer.
- The temperature inside is -7 degrees Celsius.
- Fans blow frigid air onto the waffles as they spiral through the freezer.
- It takes just 20 minutes to freeze and preserve these freshly baked waffles.
- The frozen waffles now merge into lanes to be sorted for stacking.
- A trapdoor system releases them, three at a time,
- to grippers that move them onto a conveyor.
- The conveyor lane narrows, which forces the waffle stacks into a single row.
- A sensor-activated gate releases the stacks, two at a time, to the packing station.
- It takes just a second for the two stacks of frozen waffles to be wrapped and sealed in a tight cellophane packet.
- Then it's into a metal detector.
- To demonstrate how it works, a coin was placed on one of the packages.
- The system senses it immediately and a blower blasts the package off the conveyor.
- Suctioning fingers now pick up the outer box
- and open it as they place it on the conveyor.
- A ram shoves the waffles into the box.
- And that merits a toast. Or indeed a toaster.
