油辣椒制品流场数值分析

为研究油辣椒制品的均匀灌装技术,以油辣椒制品的均匀搅拌为研究内容,以油辣椒固液二相流混合物为对象,分析平直桨叶倾角分别为0°、30°、45°、60°时的搅拌效果。以Fluent软件为计算平台,对运算结果进行分析得到,桨叶倾角30°时搅拌效果较理想,但底部仍存在局部搅拌死角。减小桨叶与搅拌槽底部距离后重建模型,结果表明,混合物流动情况进一步改善,固相在混合物中分布均匀,与预期效果相符。可将此方法作为油辣椒制品自动化灌装技术的研究数值计算方法。

Analysis of numerical simulation of flow field of fried capsicum sauce

In order to research the even filling technology of fried capsicum sauce products, taking uniformly stirring of fried capsicum sauce products as the research content, solid-liquid mixture of fried capsicum sauce as the research object, the stirring effect was analyzed with the flat blade angle as 0°, 30°, 45° and 60°. Fluent software was calculation platform and the results of calculation was analyzed, which was that the ideal stirring effect was when the blade angle was 30°. But there were still dead angle on the bottom of the groove. After reducing the distance between the blade and the bottom and renew the model, the calculated results shown that the mixture flow situation was further improved, the solid phase was well-distributed in the mixture, which was consistent with the expected effect. The method can be a numerical calculation method to study the automatic filling technology of fried capsicum sauce.
