Amino acid granules for animal feed are typically produced by fermentation, evaporation and fluidized bed granulation with drying processes. Evaporation is one of the most energy-efficient processes to remove water. However, a fluidized bed granulation process with drying is a relatively energyinefficient process to remove water. Improving solubility of amino acid is good strategy to increase the maximum achievable concentration in the evaporation process. An increase in the maximum achievable concentration can lead to energy saving by increasing the contribution of water removal by evaporation. In this study, a manufacturing method of neutral amino acid granule for feed additive using calcium hydroxide addition was developed. Since solubility of neutral amino acid is increased with increasing amount of calcium hydroxide, adding calcium hydroxide is a useful method to improve energy efficiency of the evaporation process. It was found that adding calcium hydroxide reduced steam consumption levels of tryptophan, threonine, valine and isoleucine by 8.0%, 28.0%, 26.3% and 15.6%, respectively.

Advanced Powder Technology

ADVANCED POWDER TECHNOLOGY 的目标是满足对整合粉末和颗粒材料科学技术研究各个方面的国际期刊的需求。该杂志通过发表原创研究论文、快速交流、评论和全球著名研究人员的翻译文章来实现这一目的。ADVANCED POWDER TECHNOLOGY 的编辑工作，该杂志的前身是日本粉末技术学会国际期刊，现在是由杰出的董事会成员共享，他们在一个独特的框架内运作，旨在应对全球对粉末和颗粒以及由它们生产的各种材料的文章日益增长的需求。先进粉末技术涵盖各个领域，但讨论粉末并且在文章中需要粒子。主题包括：在气体和液体中生产粉末和颗粒材料（纳米颗粒、精细陶瓷、药物、新型功能材料等）；气溶胶和胶体处理；粉末和颗粒表征；动力学和现象；计算与模拟（CFD、DEM、蒙特卡洛法、人口平衡等）；粉末过程的测量和控制；粒子修饰；粉碎;粉末处理和操作（储存、运输、造粒、分离、流化等）

The goal of "Advanced Powder Technology" is to meet the international journal's demand for research in all aspects of powder and particle materials science and technology. The journal achieves this by publishing original research papers, rapid communications, reviews, and translated articles from globally renowned researchers. The editorial team of "Advanced Powder Technology" consists of distinguished board members who operate within a unique framework aimed at addressing the growing global demand for articles on powders, particles, and the various materials produced from them. The journal covers a wide range of fields, focusing on powders and requiring the inclusion of particles in the articles. Topics include: the production of powder and particle materials in gases and liquids (such as nanoparticles, fine ceramics, pharmaceuticals, and novel functional materials); aerosol and colloid processing; characterization of powders and particles; kinetics and phenomena; computational and simulation methods (such as CFD, DEM, Monte Carlo methods, population balance, etc.); measurement and control of powder processes; particle modification; milling; and the handling and operation of powders (such as storage, transportation, granulation, separation, fluidization, etc.).
