Design and Construction of a Small Scale Sugarcane Juice Extractor

Abstract

The production of sugarcane is increasing in Nigeria nowadays. Juice extracted from sugarcane can be used extensively in manufacturing brown sugar, industrial sugar and bioethanol fuel through the process of fermentation; hence, the need to develop a machine that can extract juice from sugarcane effectively. This work involves the design, fabrication and performance evaluation of sugarcane juice extractor. The machine was designed to extract juice from sugarcane at small scale level suitable for small and medium scale sugarcane processors. The prototype machine was designed, fabricated and assembled in the Department of Agricultural and Bio-resources Engineering, Ahmadu Bello University, Zaria. The machine consists of rollers, gears, cane guide, juice collector, frame, and prime mover. The developed machine was evaluated using koma variety of cane and obtained an output capacity of 148.2 kg/h and extraction efficiency of 67.44%, respectively at a speed of 30 rpm. The production cost stood at N 90,000 which is affordable and therefore recommended for small scale processors.

Extraction and Characterization of Cellulosic Fiber from Banana, Sugarcane, and Napier Grass

“…Dew Extractor Machine. The developed dew extractor machine designed in this study was based on the system and calculations of [16] study about a small-scale sugarcane juice extractor. The machine is composed of four sections which are: feeding and crushing sections, power section, torque and speed reduction section, and frame section.…”

“…The density of the crushing roller material is equal to 7840 kg/m3, and the acceleration due to gravity is equal to 9.81 m/s2. The force and torque of the crushing roller were determined in reference [16]. Utilization, calculation, and analysis were considered with reference to [20] in order to obtain the necessary power and speed to operate the machine's entire system.…”

Rancang Bangun Mesin Pemeras Tebu 3 Roll dengan Penyajian Otomatis

“…Ukuran tebu yang relatif berbeda akan berpengaruh pada tekanan dan daya cengkram roll, sehingga perlu pengaturan mesin penggerak agar kecepatan roll stabil [6]. Pengaruh kecepatan roll terhadap kapasitas dan efisiensi hasil pemerasan juga telah ditunjukkan pada penelitian [7] dan [8], dimana jika terlalu cepat roll berputar waktu pemerasan lebih singkat namun efisiensi akan rendah. Begitu juga sebaliknya.…”

“…Efisiensi mengukur berapa persen berat air tebu yang dihasilkan dari berat tebu awal. Tingkat efisiensi pada beberapa mesin diantaranya pada [10] adalah 61%, sementara efisiensi terbaik pada [7] adalah 67,4%. Efisiensi pada [11] berkisar antara 72.53-83.9%.…”
