Abstract

A spray dryer is a device that transforms liquid feed into solid particles. In the spray drying method, the feed is atomized into a heated drying medium, causing the water content in the feed to evaporate. Generally, the spray drying method is extensively employed in the food, beverage, and pharmaceutical industries. Particle deposition is a recurring issue encountered during the operation of spray dryers. Particle deposition can lead to a decline in the quality of the produced goods. Maltodextrin is a coating material often added to reduce the rate of particle deposition on the walls of spray dryer chambers. This research aims to calculate the magnitude of particle deposit flux on the walls of a spray dryer chamber, ascertain the resulting product quality, and obtain maltodextrin powder that complies with quality standards. The study commences by creating maltodextrin solutions with concentrations of 10%-w/w, 20%-w/w, and 30%-w/w. Subsequently, the maltodextrin solutions are dried using a spray dryer under operational conditions of feed flow rates (0.01 L/min; 0.02 L/min; 0.03 L/min), drying chamber wall temperature of 120°C, drying time (30, 40, 50 minutes), drying air flow rate of 199.403 m3 /h, and drying air temperature of 60°C. The moisture content of the maltodextrin powder product is tested using an oven method. The results reveal that the lowest average particle deposit flux is 1.067 g/h.m2 , achieved at a feed flow rate of 0.01 L/min with a maltodextrin concentration of 10%-w/w. Meanwhile, the highest average particle deposit flux is 21.26 g/h.m2 under the conditions of a feed flow rate of 0.02 L/min and a maltodextrin concentration of 30%-w/w. The average moisture content test results of the maltodextrin powder exceed the standard SNI 7599-2010, reaching 5.44%.

Additional Information:	Spray dryer merupakan alat yang mengubah umpan cair menjadi butiran padatan. Pada metode spray drying, umpan disemprotkan ke dalam media pengering yang panas dan membuat kandungan air dalam umpan menguap. Secara umum metode spray drying banyak digunakan pada industri makanan, minuman, dan obat-obatan (farmasi). Deposit partikel merupakan salah satu masalah yang sering dijumpai pada pengoperasian spray dryer. Deposit partikel dapat menyebabkan menurunnya kualitas produk yang dihasilkan. Maltodekstrin merupakan bahan penyalut yang biasa ditambahkan untuk menurunkan laju deposit partikel di dinding ruang spray dryer. Penelitian ini bertujuan untuk menghitung besarnya fluks deposit partikel di dinding ruang spray dryer, mengetahui kualitas produk yang dihasilkan, dan mendapatkan bubuk maltodekstrin yang sesuai dengan baku mutu. Penelitian ini diawali dengan membuat larutan maltodekstrin dengan konsentrasi 10%-b/b, 20%-b/b, dan 30%-b/b, kemudian melakukan pengeringan larutan maltodekstrin dengan spray dryer pada kondisi operasi laju alir umpan (0,01 L/menit; 0,02 L/menit; 0,03 L/menit), suhu dinding pengering 120oC, waktu pengeringan (30, 40, 50 menit) dan laju udara pengering 199,403 m3 /h serta suhu udara pengering 60oC. Kadar air produk serbuk maltodekstrin yang dihasilkan diuji dengan metode oven Hasil fluks deposit partikel rata-rata terendah didapatkan sebesar 1,067 g/h.m2 ketika laju alir umpan 0,01 L/menit dengan konsentrasi 10%- b/b sedangkan fluks deposit partikel rata-rata tertinggi sebesar 21,26 g/h.m2 pada kondisi laju alir umpan 0,02 L/.menit dan konsentrasi maltodekstrin 30% b/b Hasil uji kadar air bubuk maltodekstrin rata-rata melebihi SNI 7599-2010 yaitu sebesar 5,44%.
