Research On Dough Sheet Resting Technology And Development Of Resting Equipment

The homogenization of noodle industry in China is a serious competition phenomenon,and improving the quality and efficiency of products is the main countermeasures of enterprises at present.China has not paid enough attention to noodle processing technology for a long time,and there is also a lack of systematic research in theory.Further research and exploration are needed to accurately and quantitatively evaluate the processing technology of noodles and further improve the noodle quality by changing the technology.Therefore,this paper focuses on the research on the curing technology in noodle processing.Based on constructing the evaluation method of the curing process,the curing mode and parameters are further optimized.Meanwhile,the resting equipment is developed,providing an effective research method for the transformation from experience to intelligence of the surface making technology.The main contents and results of this study are as follows:In this study,the physical property measurement method,image processing and analysis technology were used to optimize the dough sheet property measurement method by measuring the texture properties of surface with different thickness.The texture characteristics of dough sheet were measured by testing different thickness of dough sheet.The method of making and analyzing the images made by different dyes,different slice thickness and different magnification were obtained.Experiments were carried out on the dough made of different resting time to verify the scientific evaluation method of resting process.At last,the maturing process evaluation method established in this study was used to test the reating process of dough with different maturing methods,different resting time and different resting temperature,and the optimized resting parameter of dough sheet was concluded that the best resting method is dough followed by dough sheet rest,the optimal resting temperature of dough sheet is 35℃,and the resting time is 30 minIn this study,3D drawing method and CFD numerical calculation were adopted in the development and research of dough sheet resting equipment.The structure of dough sheet resting equipment was designed by analyzing the technological requirements of dough sheet resting.The characteristics of different air distribution are analyzed to determine the air circulation form of resting chamber.The geometric model of the resting equipment was established to simulate and calculate the difference of temperature change in the resting room and the difference of temperature field,velocity field and humidity field distribution in the resting room when the inlet wind speed was 3.61m/s,7.22m/s and 10.83m/s respectively,so as to determine the optimal inlet wind speed as 7.22m/s.Finally,the research completes the development of the dough sheet resting equipment and the performance test of the prototype,and obtains the temperature field,humidity field and velocity field of the main section of the prototype.
