核桃粉末油脂中试生产工艺实践

传统的粉末油脂生产工艺中水相配制时由配制罐中的搅拌器加速溶解，而壁材加入水中后漂浮于水面上，壁材溶解速度较慢、易结团、极易形成气泡导致乳化效果不佳。为此，以核桃油为试验材料，对核桃粉末油脂中试生产线进行工艺优化和实践，通过在配制罐底部设置胶体磨和循环管道，实现了壁材的快速溶解。所生产的核桃粉末油脂色泽为乳白色，含油率为22.15%，包埋率为92.87%，溶解度高达99.35%，可直接添加至速溶产品中应用。

Pilot production process practice of walnut oil powder

In the traditional oil powder production process, the wall material is accelerated dissolved in the water by the stirrer in the preparation tank, while the wall material floats on the water surface after being added to the water, and the wall material is slow to dissolve, easy to agglomerate, and easy to form bubbles, resulting in poor emulsification effect. Therefore, the walnut oil was used as the test material, and the process of pilot production line of walnut oil powder was optimized and put into practice. The rapid dissolution of the wall material was realized by setting up colloid mill and circulation pipeline at the bottom of the preparation tank. The walnut oil powder produced was opalescent in color, with an oil content of 22.15%, embedding rate of 92.87% and solubility of 99.35%, which could be directly added to the instant product.
