摘要：对于家庭而言，酿酒始终是个复杂繁琐的过程，工艺流程的操控学习成本太高，所以一直以来工程厂区式的酿酒流程最为成熟，但随着人们对生活品质的逐步追求且食品行业的各种问题，一些家庭更倾向于自己烹饪，对于喜好酒的人来说，家用酿酒更是已经是自己生活的一部分，综于上述理由，家用酿酒的市场变得越来越大，家用酿酒器的设计及制造已经成为了一个新型产业，但现在种类还较少，可以进行进一步的优化与设计。70590

本文首先介绍了酿酒的工艺流程，依据酿酒的工艺流程，从而确定所设计的酿酒器的工艺要求，在本文中，需满足恒温、充分混合的工艺要求，为此，设计了恒温系统以及双螺带桨叶的选用，恒温系统能够保证发酵的成功率，双螺带能够使搅拌更充分。同时，为了验证搅拌的充分性，还进行了cfx的流场分析验证。

除了满足最基础的酿酒工艺，本文还设计了压滤机以及酒精浓度报警器，压滤机的使用以及酒精报警使酿酒器更方便，在达到了所需的酒精浓度能够报警并提醒用户，压滤机在出酒的时候能够充分过滤滤渣。

Design of domestic wine making device

Abstract：For the family, making wine is always a complex and cumbersome process and the process of learning is too high, so the engineering plant has been the most mature wine-making process. With the gradual pursuit of quality of life and the food industry's problems, some families intend to cook by themselves. For those who like wine, making wine in home is already part of their own lives. In summary, the domestic wine market has become increasingly large, home brewer design and manufacturing has become a new industry. But now the species is still less，which can be further optimized and designed.

This paper introduced the process of wine at first. According to the process of wine, we know the requirements of the brewing process. In this paper, the design of the thermostat system and the application of double helical ribbon impeller that satisfy the need of conserving constant temperature and the fully mixing process. Constant temperature system can guarantee the success rate of fermentation, double helical ribbon impeller can make the mixing more fully. At the same time, in order to verify the adequacy of the agitation, the flow field analysis was also carried out.

In addition to meet the most basic brewing process, this paper also designed a filter and alcohol concentration alarm. The use of the filter press and the alcohol alarm make the brewer more convenient, to reach the desired concentration of alcohol can alarm and remind the user, the filter press in the wine when the filter can be fully filtered.

key words：the flow field analysis，conserving constant temperature，helical ribbon impeller
