Akýþkan Yataklý Sürekli Bir Kurutucuda Göl Tuzu Kurutulmasýnýn Deneysel Ýncelenmesi

Bu çalýþmada, bir akýþkan yataklý sürekli kurutucu (AYSK) tasarýmý yapýlarak prototip imalatý gerçekleþtirilmiþtir. Endüstriyel alanda kullanýlan göl tuzu, bu kurutucuda kurutma iþlemine tabi tutulmuþtur. Kurutma sürecinde kurutma havasýnýn hýzý, sýcaklýðý ve tuzun kütle deðiþimi deneysel olarak incelenmiþtir. Kurutucudaki kurutma havasýnýn hýzý iþlem baþlangýcýnda 4.5 m/s olarak ölçülmüþ ve tüm deneylerde sabit tutulmuþtur. Deneylerde kullanýlan göl tuzunun baþlangýç nemi 0,044 gsu/ gkuru madde olarak belirlenmiþtir. Bu tuz, üç farklý kurutma havasý sýcaklýðýnda 90 dakikalýk kurutma iþlemlerine tabi tutulmuþtur. 94 oC, 126 oC ve 171 oC sýcaklýklarda yapýlan kurutma iþlemleri sonrasýnda tuzun nemi, sýrasýyla 0.033, 0.024 ve 0.009 gsu/ gkuru madde’ye indirgenmiþtir. Bu sonuçlardan yararlanýlarak tuzda 0.005 gsu/ gkuru madde nem miktarýna ulaþýlabilmesi için kurutma havasý sýcaklýðýnýn 181.511 oC olmasý gerektiði hesaplanmýþtýr.

Investigated By Experimentally for Drying Lake Salt in a Fluid Bed Continuous Dryer

In this study, a fluid bed continuous dryer was designed and implemented as a prtotype. The lake salt used in the industry was carried out the drying process in this drier. The speed and temparature of the driying environment’s air and the salt’s mass was investigated by experimental. In the begining, the air speed of the drying was measured 4.5 m/s and it was kept on constant during the experiment. The initial humidty of the lake’s salt used in experiments was determined 0,044 gwater/ gdry matter . The salt was dried with 90 minutes time span for three drying temperatures separetely. After the drying processes at 94 oC, 126 oC and 171 oC, the humitities were reduced 0.033, 0.024 ve 0.009 gwater/ gdry matter recpectively. Using the results data, drying air temperature was determined 181.511 oC for reaching the 0.005 gwater/ gdry matter of the salt.
