ABSTRAK
Umbi porang (Amorphopallus campanulatus) merupakan tanaman hutan yang mulai dikembangkan di Indonesia pada tahun 2003. Umbi porang termasuk tanaman lokal yang memiliki kandungan glucomannan 15-64%, selain itu juga umbi porang mengandung karbohidrat, pati, polilosa, dan serat kasar itu kira – kira 14% dan 8% masing – masing. Tepung porang yang berwarna cokelat diduga karena masih banyaknya komponen pengotor pada permukaan granula glukomanan secara fisik dan reaksi pencokelatan secara enzimatis dan non enzimatis secara kimiawi. Di Indonesia, metode Porang merupakan salah satu jenis tumbuhan umbi-umbian, berupa semak (herbal) yang dapat dijumpai tumbuh di daerah tropis dan sub-tropis. Belum banyak dibudidayakan dan ditemukan tumbuh liar di dalam hutan, di bawah rumpun bambu, di tepi sungai dan di lereng gunung pada tempat yang lembab. Mesin penumbuk porang akan digerakkan oleh system rotary sebagai penyalur tenaga dari motor menuju alu penumbuk.Sehingga proses penumbukkan terjadi secara kontinyu dan cepat.Pada mesin penumbuk ini mempunyai prisnsip kerja dari gerakkan melingkar menjadi gerakan lurus atau linier. Kapasitas proses penumbukkan adalah ditentukan 80 kg/jam dengan diamter umbi porang 5 cm dengan berat 100 gram. rotary akan digerakkan oleh poros yang terhubung langsung dengan motor bagian ujungnya. Penggerak bagian tengah akan kontak langsung dengan gigi rack yang mengubah gerak melingkar menjadi gerak maju mundur menumbuk.
ABSTRACT
Porang tuber (Amorphopallus campanulatus) is a forest plant that began to be developed in Indonesia in 2003. Porang tuber is a local plant which contains 15-64% glucomannan, besides that porang tuber also contains carbohydrates, starch, polylose, and crude fiber which is approx. approximately 14% and 8% respectively. The brown color of porang flour is thought to be due to the presence of many impurities on the surface of the glucomannan granules physically and chemically enzymatic and non-enzymatic browning reactions. In Indonesia, the Porang method is a type of tuber plant, in the form of a bush (herb) which can be found growing in tropical and sub-tropical regions. It has not been widely cultivated and is found growing wild in forests, under bamboo clumps, on river banks and on mountain slopes in damp places. The porang crusher will be driven by a rotary system to distribute power from the motor to the pounder pestle. So that the pounding process occurs continuously and quickly. This pounder has a working principle from circular motion to straight or linear motion. The capacity of the crushing process is determined to be 80 kg/hour with a porang tuber diameter of 5 cm and a weight of 100 grams. rotary will be driven by a shaft that is connected directly to the end of the motor. The center drive will be in direct contact with the rack teeth which converts circular motion into back and forth pounding motion.
