Jackfruit is a fruit that many people like because of its sweetness, but it is one of the important unused fruits. Extensive research has been done on the added value of jackfruit, but the machining of jackfruit for separating bulbs remains of great interest. Therefore, in order to facilitate the extraction of bulbs, we have developed a semi-machining machine for removing the core of jackfruit and dividing the fruit. The test was carried out by processing fruits of three different lengths, small (15-30 cm), medium (30-45 cm) and large (45 cm or more), at different cutting speeds of 600,700,800 rpm. When operated at a cutting speed of 800 rpm with the developed machine, the core removal rate was 96%, 89.5%, 71.3% and the fruit damage rate was 12.2% for small, medium and large size fruits. It was 8.6% and 4.1%. The total time required to cut and separate the bulbs using the developed machine was 7.10, 10.0 and 12.4 minutes for small, medium and large fruits, 13.25, 18.07, and 27.20 minutes. Less than manual processing by experts. The throughput capacity of the machine for small, medium and large fruits was 66 kg / h, 114 kg / h and 144 kg / h, respectively. The total cost of the developed tool was about 20,000 rubies ($ 295) and the total operating cost was about 52 rubies ($ 0.77) per hour. The developed machine can be operated by the average person with minimal labor and is ideal for small to large processors and entrepreneurs.
The purpose of this study was to evaluate alternatives to reduce energy consumption applied to soil clearing. To do this, we developed an experimental device and evaluated the operation of the vibration-induced parameters. System integrated components for on-site evaluation: Frame tool carrier with introduction of three-point hitch and depth control mechanism system: Introduction of three sensors to measure tillage force, torque and frequency of subsoiler vibration Met. The oscillating impact force was applied through the rod and crank mechanism in the subsoiler whose motion was provided by the hydraulic motor. The device evaluation was complemented by a signal regulator and data collection system that allowed the registration of variables of interest such as system traction, penetration, applied torque and vibration velocity. The sensor calibration results showed a system correlation of 95% or more. In the field system verification at different speeds, amplitudes and depths of tillage, the traction force was reduced by up to 50% by using vibration-induced tillage compared to the non-vibration tillage state. This study showed a significant 33% increase in traction and torque magnitude when the working depth increased from 0.30 to 0.40 m. The traction force increased by 21% when the vibration amplitude decreased from 0.0707 to 0.060 m. No significant difference was found when the tractor velocity increased from 1.5 to 2.5 kmh -1. For future research, the device developed makes it possible to determine how tilling amplitude and working depth and vibration frequency affect traction in tilling work.
