This type of concentrator has the advantage of using a liquid conduction ring and an ultrasonic transmitter to increase the ability to evaporate water and break up sugar crystallization in honey, contributing to improving the quality of honey products during the concentration process. Applying the multi-factor experimental research method to study the simultaneous influence of concentration temperature, liquid conduction ring height, and ultrasonic emission time on the total score of honey quality. The experimental research results have determined the optimal value of the input factors when the optimal value of the total score of honey quality reaches its extreme. The above research results are an important basis for completing the design and manufacturing of concentrator sizes with different capacities suitable for the scale of each production facility. 05 05 2026 05 05 2026 408 33 https://creativecommons.org/licenses/by/4.0/deed.en_US 10.37394/232015.2026.22.33 https://wseas.com/journals/ead/2026/a665115-011(2026).pdf Mudiyanselage, Sarasie, Apan, Armando, Maraseni, Tek, and Altarez, Richard Dein D, Decoding the impacts of space and time on honey bees: GIS based fuzzy AHP and fuzzy overlay to assess land suitability for apiary sites in Queensland, Australia, Applied Geography, 2023. doi.org/10.1016/j.apgeog.2023.102951.
