INTRODUCTION
The summer practices in faculty of engineering are become compulsory in order to convert the theoritical knowledges that are obtained during education period, into the practices that are really essential in the business period.
Although I and my friends are students now we will be engineers in any organisation after a short time. Those, we have to appreciate these summer practices well and these summepractices gain too many advantages to us. So, the observations and searchings those are done about; the works in the organization, informations about the responsibilities of the all departments’ staff and their relationships, the things those must be done in the plant
and the other topics are belong to the student’s own and to his/her responsibility.
THE REPORT’S OWN LABRATORY APPARATUS
* Sensible balance
=> weighing materials
* Balance
* Infrared spectroscopy
=> controlling moisture content
* Etuv
* Ash owen => controlling ash
* Distillation apparatus => distillating water
* pH meter => measuring pH
* Refraktometer => controlling glucose brix
* Shaker for sedimentation => shaking
* Desicator => preventing the gaining moisture
* Gluten dryer => drying the wet gluten
In labratory , we use the analytical methods such as gravimetric , volumetric and spectroscopic
In determination of moisture content by infrared spectroscopy , we used spectroscoric analytical method.Also in sedimentation index , volumetric ; and in determination of amount of ash gravimetric analysis is used.
We have not done any microbiological analysis in labratory since there is not any apparatus.
There is not any chemical or microbiological test on water which we used for production ; only the water is distilled.
QUALITY CONTROL OF RAW MATERIAL AND PRODUCT
MOISTURE CONTENT :
* Sample is put into apparatus
*Result is recorded as % moisture content
We looked for the moisture content of flour , biscuit , wafer
DETERMINATION OF SEDIMENTATION INDEX
* 3,2 gr flour is weighed and put into covered graduated cylinder
* 50 ml bromfenol blue solution is added into cylinder and the graduated cylinder is shaked rapidly.
* It is put on shaker for 5 minutes
* Than 25 ml of lactic acid prapanol solution is added and again put on shaker for 5 minutes
* And than cylinder is put on levelled place and waited for 5 minutes
* Volume of sedimentation is recorded.
CALCULATION :
( recorded value ) * ( 100 – 14 )
sedim value = ——————————————————-
( 100 – humidity )
DETERMINATION OF GLUTEN :
Gluten is a matter which occurs from expanding of proteins by gaining water . Wet gluten can only be get from wheat in cereals. It is an important criter on making yeasted bread.
Determination of amount of wet gluten is phscochemical analysis and it depends on washing the dough which is prepared from wheat flour , with water.
Dough is prepared in glass from 5 gr of wheat flour and 2.5 ml of % 2 salt solution. It is mixed and after waiting 2-3 minutes , dough is washed and starch is separated fom dough.
After than dough is dried in gluten drier. Amount of gluten is weighed ( D1 ) and recorded.
CALCULATION :
D1
% gluten = ———————————————- * 100
TOTAL WEIGHT OF DOUGH
GLUCOSE BRIX CONTROL
* Glucose brix is measured by refraktometer and recorded.
DETERMINATION OF AMOUNT OF ASH
* The crucible is taken from desicator and weighed ( M0)
* 3-5 gr of flour is added into crucible and again weighed ( M )
* And than crucible is put into ash owen for 2-2,5 hour
* After ash owen it is put in etuv for cooling
* And than the crucible is weighed ( M1 )
CALCULATION
( M1 – M0 ) * 100 *100
% ASH = ———————————————-
( 100 – R ) * M
M1 => after owen ,weight of crucible
M0 => weight of empty crucible
M => weight of crucible and weight of flour
R => Humidity
Ash is an important criter , it shows us the amount of mineral matter. Big amount of mineral matter is found in bark of wheat. So , while wheat was grinding if the bark can be separated exactly , amount of ash will be small amount. In addition , there are some enzymes in bark and they cause spoilages and make difficult of digestion.
At the same time , when the flour with the larege amount of ash is used , the products such as biscuits contains large amount of ash and it does not adjust TSE.
During the production , the quality control is made by production manager. He looks for the availability of products. He controls the cooking , pacjaging of the products.
After production , we get samples from the products in certain time durations , and control the quality of products. We look the moisture content and ash content of the products.
TSE
WAFER
* Wafer must be as its own flavour and smell
CHEMICAL SPECIFITIES
Wafer Covered wafer
Moisture content maximum % 6 —–
Water activity maximum —– 0,4
Amount of ash in dried matter 0,75 1
BISCUIT
* Bıscuıt must be brittle and as its own flavour and smell
GENERAL SPECIFITIES
* Moisture content in pure biscuits must be maximum % 6
* Amount of ash in biscuits with salt must be maximum % 1,5
in biscuits with sugar must be maximum %1,0
in pure biscuits must be maximum % 1,0
in non-pure biscuits must be maximum % 3,0
GLUTEN SPECIFICATION
Minimum % 7 – Maximum % 12
% 7 – 9 gluten in flour is used for products with small amount of oil
% 9 – 10 gluten in flour is used for chisel tips such as petit beurre
% 10 – 12 gluten in flour is used for cake and craker
*** In our experiments we found % gluten in 9 – 10 range and
it adjusts TSE
SEDIMENTATION SPECIFICATION
36 and large very good
25 – 36 good
15 – 24 enough
14 – small not enough
***sedimentation value shows the quality of gluten if it has low value in flour , the product will be spread extremly. At the same time if it has high value , the product will not be spread enoughly.
*** In our experiments we found sedim value 28 – 31 range and it is a good value for production
*** In our experiments we found the moisture content of flour % 10 -11 range , and we found the amount of ash of flour % 0,3 – 0,4 range ; so our founded results adjust TSE
CONCLUSION
In this summer practise I converted my theoretical knowledges which we learn up to know to practise, and also I get informations about our working areas.
Looking factory ; There is one food engineer and also is not enough for this factory. Because engineer works as a production manager and he can not do more works at the same time. As a result of this ; usually he does not control the quality of material or con not control the workers. And also this causes the fall of profile.
The works on factory , is not operated by automotion techniques ,that is human power becomes more significant. This may have some advantages together with some disadvantages.
Using man power contributes to the Turkish economy as a job area for employers. However , in such factories which use the man power at high proportions , should be more careful during production. The food production requires really hygenic conditions. The importance of hygenity must be explained to workers clearly and the all necessary equipments must be supplied by management. These conditions must be made by this factory too as a respnsibility of organisation.
Also ; in order to get a good yield on production , the relationships between workers and staff should be better , the needs of workers might be supplied well. Another observed point is that ; instruments in the labratories are old and these devices should be renewed by following new technology. This is important in order to get accurate and correct results. And also ; the machines which are used during the production must be renewed. Because the quality of products is falling down. For example the owens , which are used for cooking biscuits , don’t cook exactly. Because it is so old , the biscuits in production band are cooked differently. In addition to this , packaging machines are old so wastage in packaging is increased in important case. Beside these , during my practise any chocolate production didn’t operated. So I couldn’t get any information about chocolate production. Because of this my pracctise text does not include chocolate production. In this factory , chocolate production is made in only winter.
All above mentioned cases are observed by me during my practise term. This practise gained me new experiences ; such as How to attitude on the plant ? , How an engineer interfere to any problem in any production ? , What are the responsibilities of engineer ? and so on. Briefly I get many informations and experience related with Industry.
