“…Thus, these four factors are selected as the variables of the orthogonal test of numerical simulations. According to cane sugar engineering practices (Rein, ), Tube d takes value in the range of 100–120 mm, Tube l takes in the range of 900–1,500 mm, Downtake d should be 0.4 times the crystallizer diameter, and Level h should be in 1.2–1.6 m. In this study, we scale down them due to our experiment equipment limitation (Meng et al, ; Meng, Wei, Wei, Chen, & Cui, ). Each variable divided into four levels.…”

“…The anemometer probe was installed on the midpoint of downtake and 27 cm from the bottom of the crystallizer. Tests were performed through the sugar evaporative crystallization system based on our laboratory platform (Meng, Wei, et al, ; Meng, Zhang, et al, ), and in order to reduce the experimental error, each test was repeated three times. Sugar with a brix of 91 was used for test.…”

This article describes an optimization design of a sugar evaporative crystallizer using numerical simulation experiments. Computational fluid dynamics (CFD) is used to simulate the circulation flow of sugar juice in the crystallizer, and the numerical experiments are designed according to orthogonal experiment matrix. First, based on the specific working characteristics of sugar evaporative crystallizer, major factors influencing the cane sugar evaporative crystallization process were identified. Then CFD software was utilized to establish various three‐dimensional CFD models of the sugar evaporative crystallization with different factors and levels. Statistics software (IBM SPSS) is used to analyze the CFD simulation results. In order to measure circulation velocity under different conditions, physical experiments were conducted in the experiment platform in our laboratory. The circulation velocity measured under the optimal condition was increased by 128%, and the crystallization efficiency could be guaranteed. Practical Applications Computation fluid dynamics (CFD) enables studying the details within the crystallizer, making the invisible become visible. The orthogonal test replaces all tests with partial tests. The orthogonal test coupled CFD technique can hugely decrease the cost of optimization design. The application of this method will benefit the optimization design of food engineering.

“…(1) e roller and the spiral blade are welded together, while the cutters and the spiral blade are bolted. In the simplified model, parts such as bolts and nuts are ignored and the material of the loading cutter roller is taken to be isotropic and linear elastic to reduce the simulation time [35][36][37]. (2) It is assumed that throughout the cutting of the silage material, the rotational speed and the vertical forward speed of the loading cutter roller are constant, and the distance between the roller shaft and the silage material is defined in the same plane; that is, the cutting depth of the silage material is taken to be constant.…”

Simulation analysis and parameter optimization are performed for the loading and mixing devices of a self-propelled total mixed ration mixer. To reveal the three-dimensional movement of silage material under the action of the loading cutter roller, the latter is modeled using SolidWorks software. ANSYS/LS-DYNA software is used to simulate the process of silage cutting, which is modeled using smoothed particle hydrodynamics coupled with the finite element method. e cutting force and power consumption are simulated, and the behavior of the equivalent strain of the silage is determined. e results showed that silage was broken up mainly by extrusion and shear force due to the loading cutter roller. e power consumption according to the simulation is consistent with the value from an empirical formula, confirming the validity of the proposed modeling method. To study the mixing performance and obtain the optimum parameters of the mixing device, the Hertz-Mindlin model is used for the interaction between material particles and mixing device. A three-factor, five-level method is used to optimize the mixing performance. Material-mixing time, loading rate, and auger speed are chosen as experimental factors and mixed uniformity as an evaluation index. It is found that auger speed and material mixing time have significant effects on mixing uniformity. ese results provide reference values allowing the analysis of the crushing of silage and selection of the optimum parameters for mixing performance.

To increase the cutting efficiency for castor stem, the castor harvester cutting device was developed. The structure of the disc cutting device was designed. Cutting blade angle, sufficient working and minor cutting edge lengths were determined, which were 20°, 73 mm and 19.8 mm, respectively. The finite element model of disc cutter for castor stem was established. The incision volume was selected as the cutting performance evaluation index. The cutting process of the cutter was simulated. The results show that the cutting performance of the trapezoidal cutter is preferable to that of the rectangular and the curved cutters. When cutting blade cuts the stem, the volume of the incision decreases first and then increases, and the size of the incision increases with the increase of cutting edge angle. When the blade angle is 10°, the cutter has the ideal cutting quality. Considering the blade angle, the slip angle, and the angle of the cutter head as factors, the virtual test of the cutter was made with the incision volume as the index. The response surface analysis was used to obtain the cutter structure parameters when the incision volume was the least. The result for the blade, slip and cutter head inclination angles are 14.06°, 19.93°, and 10.54°, respectively. The cutting efficiency evaluation index (one-time cutting) was established to optimize the cutter running parameters. The results show that when the cutter moving speed was 1.011 m/s and the cutter rotation speed was 282.0 r/min, the maximum cutting efficiency is 2.25 castor stems/s.
