“…Compared with results captured by the high-speed camera, it was confirmed that the simulation model could predict the cutting depth of corn stalk under jet action. Besides, computational fluid dynamics (CFD) models could be used to simulate water jet diffusion inside or around the jet nozzle, and the discrete element method (EDM) could establish the corn stem model [76,77]. Compared with pure water jet cutting, Perotti et al [78] found that a number of garnet abrasives (3 kg/h) could improve the jet-cutting ability of wheat stems and reduce the maximum hydraulic power required by laboratory experiments.…”

Cutting is a significant part of agricultural material processing, and the cutting technology determines the quality of agricultural products. Water jet cutting technology is a non-contact and cold cutting technology suitable for cutting agricultural materials. It can realize an environmentally friendly cutting process avoiding such problems as heat generation, sharpening and cleaning blades, and microbial cross-contamination. This paper reviews the current status of water jet cutting of six kinds of agricultural materials, including vegetables, fruits, meats, woods, stems, and soils. By analyzing how to complete different cutting operations, improve cutting ability, or control post-cutting influences, the problems and solutions of water jet cutting of each material are summarized. Then, combined with the application requirements, some suggestions are put forward for developing water jet cutting technology. The results would help researchers determine key information required by cutting agricultural materials and provide a reference for further research on water jet cutting technology in agricultural engineering.

“…Although performance of waterjet on cutting maize stalks involves a large number of variables that may somehow affect the results, only major variables were concerned in this study. Based on the previous studies [12][13][14][15] , three key parameters were selected as water pressure, traverse speed and standoff distance, and a full factorial experimental design was applied. Each parameter was assigned different levels, 10, 5 and 4 levels for water pressure, traverse speed and standoff distance, respectively.…”

Large amounts of crop stalks left in the field as a result of conservation agriculture cause blockage during no-till planting. To solve this issue, pure waterjet was used to cut off the maize stalks so that the rear furrow opener could pass through without blockage. In this investigation, an experimental study on depth of cut, which was the main performance indicator of pure waterjet on cutting maize stalks, was presented. A full factorial design with 200 tests was implemented with respect to three operation parameters, that is traverse speed, waterjet pressure, and standoff distance were considered as variables. An analysis of variance (ANOVA) was carried out in order to determine the statistical significance of individual operation parameters. Using multilinear stepwise regression analysis, a model to predict the cut of depth from the predicted pure waterjet operation to cut maize stalks was then developed. All three operation parameters significantly influenced the cutting performance. Moreover, the results indicated that depth of cut increased with the increase of waterjet pressure, the decrease of traverse speed, and decrease in standoff distance. Waterjet pressure provided major contribution to depth of cut, followed by traverse speed, then standoff distance, which was demonstrated by both ANOVA and regression analysis. The experimental results showed that when the standoff distance was closer than 10 mm and waterjet pressure was 280 MPa, all maize stalks specimen could be cutoff thoroughly. With the consideration of field operating conditions, waterjet pressure of 280 MPa or higher and 10 mm to 15 mm standoff distance were recommended for maize stalks cutting. This analysis provided a realistic approach for the optimization of the ultra-high pressure pure waterjet parameters in maize stalks cutting, which could be used to relieve the occurrence of straw blockage in no-till planting.
