🍞 The Journey of Sliced Bread from Flour to Store Shelves

This paragraph delves into the process of making sliced bread, a staple food enjoyed globally. It begins with the historical context, noting that the first bread was made by Egyptians over 5,000 years ago. The invention of sliced bread in 1928 revolutionized bread consumption by introducing a machine that automatically sliced loaves into uniform pieces. The bread-making process starts with wheat, which is cleaned, soaked, milled, and sifted to produce the desired flour. This flour is then transported to the bakery, where it is combined with yeast, oil, vinegar, sugar, salt, water, and preservatives in a giant mixer. The dough is mixed until it becomes elastic and sticky, then divided into equal pieces, shaped into balls, and molded into loaves. The yeast ferments the dough, causing it to rise, and after a period of fermentation, the dough is shaped and prepared for baking.

sliced bread is a staple food consumed

worldwide and produced in large

quantities but how is that soft and

delicious bread that we use for

sandwiches or toast made in this video

we will discover how the ingredients are

mixed to create thousands of slices of

sliced bread

is a very important food and millions of

people around the world eat it every day

it is believed that the first form of

bread was made by the Egyptians over

five thousand years ago

surprisingly the basic recipe for bread

has remained the same for thousands of

years simply mix flour and water to make

the dough and then bake it

sliced bread was invented in 1928 by an

American Baker who patented a machine

that automatically sliced the bread into

uniform slices making it easier to

consume and an instant success

it is called sliced bread because it is

cooked in a rectangular mold giving it

its characteristic shape

the process starts with flour flour is

made from wheat which is cleaned before

being transported through a 10 kilometer

long network of pipes from the silos to

the Machinery the weed is soaked in

water and left for up to 24 hours to

remove the outer husk then it is milled

with steel rollers that crush the grains

the crushed wheat passes through finer

and finer sieves removing the coarse

matter and releasing small amounts of

flour each time

this course material is sent back to the

steel rollers for further grinding and

the process is repeated until the

desired flower for sliced bread is

obtained

the finished flour is ready to be

transported to the bakery by truck the

flower is a combustible powder and in a

confined space it can create an

explosive environment where any

electrical spark could ignite it

therefore the mill must take great care

during loading the truck must be

grounded to prevent the accumulation of

static electricity while powerful fans

prevent the dust from escaping this

Bakery receives nearly a thousand tons

of flour per week as it is one of the

main ingredients for bread they store it

in huge bins called silos the Millers

deliver the flower twice a day in tanker

trucks at the heart of the factory is

the gigantic bread production line that

bakes and packages 1.5 million loaves of

sliced bread every week the flour is

pumped from the tanker truck to the top

of the silo yeast is the special

ingredient that makes the bread rise and

it needs to be kept at the proper

temperature therefore in this room

computers constantly monitor its

temperature the main ingredients are

pumped through pipes to a giant mixer

the first task is to weigh all the

ingredients flour yeast oil vinegar

sugar salt water and small amounts of

other ingredients such as fat and

preservatives the preservatives are used

to extend the shelf life of the sliced

bread and prevent the growth of bacteria

ingredients that are needed in smaller

quantities like seeds or nuts are added

by hand it requires 600 kilograms of

flour next the machine mixes all the

ingredients until they form an elastic

and sticky dough the mixing blades can

rotate extremely fast completing 360

full rotations per minute this enormous

mixer works the dough for eight minutes

resulting in a massive dough that can

fill 600 bags of sliced bread Once the

dough is well homogenized it is emptied

into a huge container

at this point the dough weighs one ton

and although it contains a significant

amount of water part of it will be lost

during the later stages of the baking

process

the dough is then divided into equal

sized pieces at the bottom of the

machine a small hole allows the dough to

come out two mechanical arms cut it into

equal pieces and each piece will become

a loaf with the help of blades the dough

is divided into small balls at a rate of

192 per minute the dough balls Then Fall

onto a conveyor belt the pieces of dough

are transformed into balls which can be

worked more easily the dough balls are

coated with flour to prevent sticking

during transport and deformation the

balls come out of the divider and enter

the molder Which shapes the dough into

balls at high speed the dough is then

folded and rolled by the machine

producing three pieces per second for a

total of 11 500 per hour the dough is

rolled until it reaches the exact size

and then it falls into baking molds

these molds are used for the yeast to

ferment a process that takes three hours

when the yeast ferments it causes the

dough to rise significantly now it's

time to let the yeast do its work and

make the dough rise after mixing and

turning the dough it needs to rest for a

few minutes during transport this

resting period allows the yeast to act

and it is called fermentation as the

dough settles on the movable shelves of

the fermentation chamber small air

bubbles form inside and soften the dough

after about eight minutes the first

fermentation is complete the dough is

then stretched and any air bubbles are

removed to give it the proper shape the

yeast creates small gas bubbles inside

the dough at a temperature of around 45

degrees Celsius the yeast breaks down

the flour in the dough forming small

bubbles of carbon dioxide that fill the

dough and make it rise after 50 minutes

of fermentation the finishing touches

are added such as a sprinkling of flour

or a seed topping once the bread loaves

have risen they are baked in large ovens

the dough loaves are ready to enter the

oven at a temperature of about 260

degrees Celsius this oven measures 39

meters long longer than a tennis court

they need to achieve the right

temperature so air is blown around the

molds to ensure even baking they are

baked for 20 minutes at 260 degrees

Celsius once baked the loaves have a

beautiful golden color just 20 minutes

later delicious freshly baked loaves of

bread appear a loaf has to be perfect if

it is going to be sold in a store all

day Bay Acres check that the bread is

just right with a great taste and the

proper size and shape when the loaves

are ready they are removed from the

molds using a tipping system the loaves

are taken out of their molds and placed

on a conveyor belt to cool a

transportation system takes the loaves

to different sections of the bakery hot

bread cannot be sliced so it needs to

cool slowly in a temperature controlled

refrigerator the bread cools while

rotating through these enormous cooling

towers for about two hours during the

cooling process the sliced bread settles

and becomes denser and more compact

helping it maintain its rectangular

shape after two or three hours of

cooling a standard crust or outer layer

forms once cooled the loaves are sent to

the slicer which Cuts 65 slices per

minute the slicing is done by 2 meter

wide and 40 centimeter long steel blades

the blades are replaced every two weeks

each loaf is sliced into 20 slices this

machine takes care of the slicing work

and then the bread is placed in bags the

slices are automatically packaged at a

rate of 65 per minute and they are ready

for distribution it has taken five and a

half hours from the dough preparation to

the packaging of the sliced bread if you
