Summer Practice Report

This factory has established by the association of Beyyem Industry Commerce. Beyyem A.Ş. was built in Ankara-Beypazarı to produce mixed feed in 1979 and it began production in 1981.

Beypi A.Ş. has established in 1986 by leading of Beyyem I.C. Beypi A.Ş.. has started poultry meat production in 1987-Agust at a slaughterhouse located in Bolu-Göynük-Dereler village. After that there became an integrated facility. The investments that have began in Beyzarı, continued in Bolu.

Now they are able o produce variety of products ranging from poultry meat to ready-to-eat foods.

In 1995 the head office of the factory has been moved to Bolu. In 2004 Beyyem has jointed to Beypi A.Ş.

Beypi was in the list of the 500 biggest companies in the Turkey, now increasing the capacity, company, facilities it is the second largest Poultry processing company in Turkey. Also Beypi A.Ş. produce its products as the name of Beypiliç. It has

Bidaş Summer Practice Report


BİDAŞ started business in Bursa, Turkey in 1975 as a coldstore which has served the fresh market but has since expanded its business into IQF fruits and vegetables as well. Its frozen storage capacity is 35.000 m3 with the daily productioncapacity of 100 mt and 20.000 mt per annum.

BİDAŞ’s Bursa plant has long years experience in preparing fruits and vegetables to exacting spesifications for well known international frozen fruit and vegetable product manufacturers.

Its exports contain 80 % of its turnover and 90 % of its exports are to EU countries. It mainly export to food professionals such as dairy producers, food ingredients producers and frozen ready meal processors.

HACCP and ISO 9002 are well established and ISO 9001:2000 should be implemented by the end of 2003. As well as IQF fruit products, which are produced in line with EEC regulations, BİDAŞ produces IQF vegetables for multinational frozen packers and retail customers. The plant has been designed in such a way that it can be very versatile to cater for all kinds of product lines. Upgraded steam blanching and packing equipment allow for top quality product manufactured to exacting standarts.

Efes Pilsen Summer Practice Report


Beer is one of the most popular alcoholic beverages for centuries. It is prepared from barley malt, row hops, brewing water and top or bottom fermenting yeasts. Also there are some extracts and carbondioxide. Beer can be obtained from alcoholic fermentation of  the malt which is mixed with water and hops under the convenient conditions.

Grains are germinated under controlled conditions to obtain barley malt. The conditions are about moisture content, temperature, the ratio of oxygen to carbon dioxide and the germination time. After grinding the malt, it is boiled, fermented, filtrated and filled. During boiling some extra enzymes are added to the crushed malt and warm water to starch and protein into their components. The dissolved product coming from the mashing is wort and the remaining part is called as spent grain. Then, the wort is cooled to 10oC and yeast is added for converting sugar into alcohol and carbon dioxide by fermentation. Yeast is removed and beer is pumped into the maturation tanks for going on slow fermentation at 0oC. At the end of the lagering it exists sediment in the tank. Finally, beer is filtered step by step and transferred to the bottling machines. After the last step, pasteurization, it is ready to drink. In the report all of these process sequences, different departments and the plant auxilaries are written. Also material and energy balances are done and in the appendix part some flow charts, lists of enzymes and experiments, and the project that is done for the plant are given.

Efes Pilsen is the biggest beer producer in Türkiye. It commands 73% of the beer demand of Türkiye. Also they are exporting a huge amount of  beer to the other countries. It was choosen eighth biggest beer company in Europe. Efes Pilsen is an important, developing and well-known trade mark both in Türkiye and in the world. So I choose Efes as the company for my summer practise.

Efes Pilsen: This is a Pils type of beer. It’s light in color and has 5.5 % alcohol. Its extract amount is 11.4-11.7 %.

Efes Light: Its alcohol content is 2% and is easy to drink.

Efes Extra: This beer contains 50% more alcohol than Pils type beer and darker in color and bitterer in taste.

Efes Dark: Its alcohol content and extract amount are same with the Efes Pilsen but its color is darker.

Marmara 34: This is a Lager type of beer. Its alcohol content is maximum 4.9 % and is easy to drink.

Becks and Miller: Their raw materials acquired through imports.


Five raw materials are required for beer production: barley, malt adjunts, hops, water, and yeast. The quality of these raw materials has a decisive influence on the quality of the final product. Knowledge of the properties of the raw materials and of their effects on the process and on the product provides the basis for their handling and processing. With such knowledge it is possible to control the technological process rationally.

2.4.1. Barley

Barley is the main raw material for beer production. Barley (Hordeum vulgare) supplies the starch required for beer production. This starch is converted to fermentable extract in the brew house. It is necessary to produce, by cultivation suitable varieties, barleys, which provide extract-rich malts.

Barley grain is usually consist of three main parts:

  • Husk and grain membrane

  • Embryo

  • Endosperm

Husk is a cellulose sheath that covers and protects the barley grain. This sheath and membrane consist polyphenol, some proteins and silicat components. The materials in the husk generally destroy the stability of beer. On the other hand, husks help for filtering of wort by forming a filter layer.

Embryo is the living part of the barley and it contains genetic material.

The most important part of the barley is endosperm, which is about 80% of the barley.

During the germination nutriment materials dissolve and used for the new cell production by the help of embryo.

The chemical composition of the barley:


14 %


54 %

Non-nitrogenic substances

12 %


10 %


  5 %


2.5 %

Inorganic substances

2.5 %

The aim in the production of malt is to loosen the grift construction and to optimize the enzyme activity. Therefore, starch in the endosperm can be extracted easily. During the production of malt, the necessary conditions for developing of the barley are formed by artificially. These conditions are; humidity, temperature, oxygen, and time.

Since Efes Pilsen has malt factories in Afyon and Konya, malt is taken from these factories. Barley and malt storage is done in deep silos that are found in the grinder part of the plant.

2.4.2. Malt Adjunts

Unmalted cereals, such as rice, maize, sorghum, barley, and wheat are often used as adjuncts. Efes Pilsen uses only rice as adjunct. Rice is acquired from domestic sources and stored in the grinder part of the plant.

Sugar (glucose) can be added during various steps of the brewing. It is used instead of forming fermentable sugar through the splitting of starch. It is also acquired from domestic sources (İzmit-Pendik Nişasta) and stored in a room in the grinder part.

2.4.3. Hops

The hop (Humulus lupulus) is a perennial, dioecious climbing plant of the hemp family belongs to the order, which also includes the nettle family. In the brewery it is the inflorescences of the female plant, which are used. These contain bitter resins etheral oils that supply bittering and aroma components to the beer.

So far as brewing is concerned hops are dried hop cones of the female plant and products made from them, which contain only components from hops.

Hops are grown in special growing regions where the necessary growth conditions exist. After the harvesting of the hops, they are dried and converted to a storable form. This has been done in Bilecik Plant that also conducts to the Anadolu Group.
