Abstract

Abstrak. Metode pendinginan kopi yang telah selesai disangrai masih banyak dilakukan secara manual dengan cara meletakan biji kopi ke wadah penampungan dengan begitu saja.  Hal ini tentu sangat berpengaruh terhadap kulitas dan cita rasa  kopi tersebut ditambah akan memperlambat proses tahapan produksi kopi selanjutnya. Penelitian ini bertujuan untuk mengetahui kinerja mesin sangrai dilengkapi dengan alat pendingin biji kopi sangrai. Penelitian diawali dengan menimbang 5 kg biji kopi robusta. Kemudian dilanjutkan dengan pemanasan mesin sangrai sampai mencapai suhu 205℃, setelah mecapai suhu tersebut biji kopi di masukkan dan disangrai sampai tingkat kematangan dark roast. Pengambilan sampel dilakukan setiap 6 menit penyangraian, kemudian di catat dan menganalisis data penelitian dari awal proses sangrai sampai akhir proses pendinginan. Hasil Penelitian diperoleh bahwa penyangraian memerlukan waktu selama 4 jam 54 menit untuk mencapai tingkat kematangan dark dan  menghasilkan rata-rata kadar air biji kopi adalah  1,41%, Kemudian dilakukan 2 metode pendinginan yaitu secara alami dan yang memakai alat pendingin biji kopi sangrai. Pendinginan alami membutuhkan waktu selama 2 jam untuk biji kopi menjadi dingin dengan kadar air biji kopi akhir yaitu 0,24%, sedangkan pendinginan menggunakaan alat pendingin biji kopi hanya membutuhkan waktu Selama 8 menit dengan kadar air biji kopi akhir yaitu 0,97 %. Total kebutuhan energi listrik mesin  penyangrai dan alat pendingin adalah sebesar 14,51 kWh.Performance Analysis of Roasting Machines Equipped With Coffee Bean Cooling EquipmentAbstract. The method for cooling coffee that has been roasted is still mostly done manually by simply placing the coffee beans in a holding container. This of course has a big impact on the quality and taste of the coffee, plus it will slow down the process of the next stages of coffee production. This research aims to determine the performance of roasting machines equipped with coffee bean cooling equipment.The research began with weighing 5 kg of robusta coffee bean material. Then proceed with heating the roasting machine until it reaches a temperature of 205℃, after reaching this temperature the coffee beans are added and roasted until the level of dark roast maturity. Samples were taken every 6 minutes of roasting, then recorded and analyzed research data from the beginning of the roasting process to the end of the cooling process. The research results showed that roasting took 4 hours 54 minutes to reach the level of dark maturity and produced an average coffee bean moisture content of 1.41%, Then 2 cooling methods are carried out, namely natural and using a roasted coffee bean cooler. Natural cooling takes 2 hours for the coffee beans to cool with a final coffee bean moisture content of 0.24%, while cooling using a coffee bean cooler only takes 8 minutes with a final coffee bean moisture content of 0.97%. The total electrical energy requirement for roasting machines and cooling equipment is 14.51 kWh.
