Analisis Temperatur Pada Proses Extruding Pelet Apung

Abstract

Bahan baku pelet didorong dan ditekan keluar pada mesin pencetak melalui suatu lubang terbatas (cetakan/die) pada ujung ulir. Pemanas memberikan panas pada bahan yang diekstrusi yang disebut ekstrusi panas. Pisau potong digunakan untuk meratakan ukuran potongan hasil ekstrusi, dan ciri utama proses ekstrusi adalah sifatnya yang kontinyu. Alat ekstruder dioperasikan dalam kondisi kesetimbangan dinamis, yaitu input setara dengan output, bahan yang masuk setara dengan produk. Akibat panas saat proses produksi pelet, menjadikan kadar air pada bahan menguap hasil pelet bisa terapung di air. The raw pellets material was pushed and pressed out on the molding machine through a limited hole (die) at the threaded ends. The heater gave heat to the extruded material called hot extrusion. Then, the knife was used to flatten the extruded cut size, and the main characteristic of the extrusion process was its continuous nature. The extruder was operated in conditions of dynamic equilibrium that was, the input was equivalent to the output, and the incoming material was equivalent to the product. Due to the heat during the pellets production process, it made the water content in the material evaporates, the pellets could float in the water.
