2025-12-03T17:39:53+07:00

Efficient transport routing is a critical strategy for minimizing logistics costs. This study compares the performance of three routing methods: current practice (experience–based), Nearest Neighbor Heuristic, and VRP Spreadsheet Solver, for distributing fresh eggs to 56 customers. Empirical results indicate that the VRP Spreadsheet Solver yields the optimal outcome, reducing average distance from 55.49 to 42.15 km/time. This corresponds to a 24.04% reduction in fuel costs (saving 40,664 THB/year), significantly outperforming the heuristic method (5.15% reduction). These findings validate the potential of quantitative decision–making tools in enhancing the competitiveness of the agricultural supply chain.

Value–Added Particleboard Development Using Waste and Recycled Materials for Sustainable Utilization

2025-12-13T09:26:05+07:00

This research aimed to develop value–added particleboard from waste and recycled materials in order to enhance the value of waste resources, promote efficient resource utilization, and support sustainable development. Engineering–based processing methods were applied to transform waste materials into new products with potential commercial applications. The primary raw materials used in this study were durian peels and areca nut husks, which were processed into particle sizes of 4 and 20 mm. Spent coffee grounds and recycled plastic pellets were employed as reinforcing materials, while isocyanate adhesive was added at proportions of 6%, 9%, and 12% by weight of the raw materials. The mixed materials were blended using a mechanical mixer with adhesive injection, weighed, and formed into boards using a mold with dimensions of 400 × 600 mm. Hot pressing was conducted under a hydraulic pressure of 30 MPa at approximately 160 °C for 10 minutes. The results indicated that particleboard produced from 20 mm durian peel particles with 12% isocyanate adhesive and reinforced with recycled plastic pellets exhibited the most favorable properties. The board demonstrated an average density of 780.02 kg/m³, an average moisture content of 4.36%, an average thickness swelling of 8.24%, and an average internal bond strength of 6.93 MPa. When compared with the Thai Industrial Standard TIS 876–2547, the physical and mechanical properties of the developed particleboard met the required specifications. These findings confirm the feasibility of utilizing waste and recycled materials for the production of sustainable and value–added particleboard.

2025-12-09T13:02:28+07:00

The development of the solar and infrared dryer with ventilation comprised installing a solar module and battery for electricity storage and supply. There were assemblages of infrared lamps and reflectors, a 60–degree tilt, to the dryer for supporting low solar radiation. The experiment was Chinda chili drying by the ventilated solar dryer with the infrared heaters 650 and 1,150 W. The initial moisture contents of chili peppers were 320.08–285.47 %db., and final moisture contents were 19.99–14.41 %db. Assessing dryer performance and energy consumption, dried Chinda chili from the solar dryer with the ventilation fan could decrease the moisture in the drying chamber. The drying time by solar was longer than by infrared. As a result of drying with infrared heaters 650 and 1,150 W, the higher infrared power showed decreased drying time, increased thermal efficiency, and lowered specific energy consumption.

Design and Construction of Semi Automatic packing machine for Rolled Rice Noodles

2025-12-09T13:02:41+07:00

The project team conducted a study of the rice noodle production process at Sinthawee Roi Et Limited Partnership and found that there were issues with the current production method. The existing process relied on manual labor for filling and sealing the bags, which caused production delays, resulting in products that lacked the desired quality and efficiency, and were insufficient to meet customer demand. Therefore, the team proposed the design and construction of a semi–automatic noodle packaging machine to assist in the packaging process, aiming to increase production to meet market needs. The results showed that the evaluation of the seal quality from the developed machine revealed that 98% of the seals were of good quality, and 96% were of proper size. The machine also showed improved performance: while the standard time for the original manual process was 44.44 seconds per bag equivalent to 650 bags per day. the new machine reduced the packaging time to 31.15 seconds per bag, allowing for 880 bags per day. The number of process steps was reduced by five, a reduction of 55.56%. The production rate increased by 230 bags per day. Therefore, compared to the original method, the production rate increased by 35.38%.
