HISTORY OF BREAD

The first bread produced was probably cooked versions of a grain-paste, made from roasted and ground loped by  accidental cooking or deliberate experimentation with water and grain flour.

WHAT IS CORN BREAD?

Corn bread’s compositions is %50 of corn flour and %50 of wheat flour.

Little salt and sugar added in these mixture, after fermented dough is baked.

INGREDIENTS

Corn flour

Wheat flour

Yeast

Salt

Water

Sugar

Oil

WHEAT FLOUR

Quality parameters;

Strength of flour gluten,

Amount of protein,

Quality of protein,

Kneading and fermentation tolerance,

Water retention capacity of the flour.

Gluten content;

Form the backbone of the dough,

Hold the CO2 gas in the dough,

Desired gluten is flexible,

As a result of these; bread is porous and high in the volume.

CORN FLOUR

High amount of carbohydrate present in corn flour,

It rich for E,  A, B2 vitamin, protein, calcium, phosphate,

Regulate blood sugar,

Good for digestion,

Rich for unsaturated fatty acid,

Regulate cholesterol.

WATER

Gives desired fluid structure of the dough,

Provide medium for fermentation,

Medium hardness water should be used,

YEAST

Increases the dough volume,

Faster CO2  production,

Yeast activities optimum temperature is; 25 – 30 ˚C,

80 – 85 % moisture

SALT & SUGAR

SALT

Adds flavour,

Improves the dough structure.

SUGAR

For easy fermantation,

For desired taste,

For desired crust color.

OIL

Make dough softer,

The amount of oil is dependent type of bread.

PACKAGING.

MIXING

White flour, corn flour, water, sugar, yeast, salt and oil are mixed.

MIXER

Homogeneous and low friction mixing action due to wide diameter spiral and peripheral dough circulation around the bowl,

Stainless steel spiral dough hook and heavy duty stainless steel bowl,

Dual speed control,

Mixing capability for small and heavy batches,

Mixing head up/down motion via hydraulic system.

FERMANTATION

Fermantation required for; high volume bread

CUT-WEIGHT

Equipment of cut and weight works accordings to volumetric principle,

Velocity  of cut:12 -16 beat /min.

ROUNDING

Rounding provide smooth surface before shaping increase properties of holding of gas,

Different models enabling dough rounding from 50 to 1600 grams between the rounding cone and adjustable or fixed rounding tracks,

Ideal and smooth rounding through long rounding tracks,

Channels with on/off switch blowing warm air to prevent dough sticking.

INTERMEDIATE PROOFER

Desired shape of dough easily.

Intermediate proofer: depending on capacity.

Number of pockets and trays vary depending on the intermediate proof time required.

The pockets and trays are easily removable for sanitation and maintenance.

SHAPING

Firstly,dough is flatten and remove of gas in the dough after give desired shape,

If dough kneading slack, gas can’t remove from dough so,occur big pores in bread,

Range of shaping will adjust correctly,

FERMANTATION ROOM

Purpose of fermentation room, provide same volume everywhere in dough before baking,

Stainless steel frames,

High efficiency by polyurethane constructed walls,

Inside lumination allowing easy observation of the proofing process.

Proof Box Climate Conditioner

Separate temperature and humidity controls for a perfectly balanced proof box condition,

Sensitive temperature control through a thermostat,

Sensitive humidity control through sensors,

Automatic water level control with a solenoid valve,

Long-life operation with stainless steel construction.

BAKING

Used revolving oven

235-240˚C(30-40 min)

 Revolving Oven

Excellent baking performance as a result of high volume, low velocity air flow and quick recovery time,

High thermal efficiency and durable stainless-steel heat exchanger and stainless-steel interior panels,

High capacity self-contained steam generating system,

Low level providing easy loading and     discharging,

Easily adjustable damper.

Revolving Oven

HISTORY

Corn, Zea mays L., a plant belonging to the grass family, is native to both North an South America.

It was the staple grain of the Indians for centuries before Europeans reached the New World.

In 1889, Theadere and Benjamin Hudnut made a machine which extracts the corn oil from corn germ.

Corn Wet Milling Lab ( Eric OLSON )

Purpose

The United States produces 9.3 billion bushels of corn each year, most of it in the Midwest corn belt.  Most  students believe that all the corn that is grown feeds farm animals or people at the annual picnic, and a good  amount of it does, but what happens to the corn not consumed by cattle, pigs or people?  A large amount of  corn never makes it to the dinner table. Corn Wet Milling is an industrial process that converts corn to a  wide variety of by-products.  The wet milling industry is the largest non-feed user of corn, using  approximately 1 billion bushels annually.  This lab looks at the separation steps in the industrial processing  of corn.   Background   Corn wet milling is a complex industrial process.  Large wet millers process approximately 100,000  bushels of corn daily, and the primary product is starch and starch derived chemicals.  This cornstarch is  then processed and used as food and industrial products.  It is routinely used as an adhesive, for  manufacture of papers, and as filler for pharmaceuticals.   It can be converted into an enormous assortment  of industrial chemicals now produced from petroleum sources. Most plastics used in the U.S. are made  from materials that come from petroleum. Petroleum products are a major problem in our rapidly filling  landfills.

Mısır Yetiştiriciliği Fizibilite Çalışması

Mısır, eski çağlardan bu yana insanoğlunun yararlandığı bir bitkidir. Orijini Amerika olup, Dünyada yayılışı, Amerika’nın keşfinden sonra olmuştur. Ülkemize 1600 yıllarında Kuzey Afrika, Mısır ve Suriye yolu ile geldiği kabul edilmektedir. Mısır hibritleri dünyada 60 derece kuzey ve 42 derece güney enlemleri arasında yetişebilmekte olup, ekiliş alanı olarak, dünyada buğday ve çeltikten sonra üçüncü sırayı almaktadır (Kırtok, 1997).

Mısır, gerek insan gıdası, gerek hayvan yemi ve gerekse endüstri hammaddesi olarak büyük önem taşıdığından bu çalışmalar içerisinde, mısır yetiştiriciliği büyük yer tutmaktadır. Mısır, tanesinden, yağ ve alkole, sap, yaprak ve sumaklarından ise kağıttan plastiğe kadar çeşitli maddeler yapılan önemli bir bitkidir. Nişasta,yağ ve yem sanayinde istenilen özellikleri taşıyan mısırın önemi gün geçtikçe artmaktadır.
