The basis of leguminous crops is peas, which have a food value for human nutrition. Peas are also used as concentrated and green feed, silage, hay, and hay flour. Pea seeds are susceptible to various diseases. One of the main reserves for increasing the production of pea grain is the use of seeds that are cleared of various impurities for sowing and pre-treatment with chemical preparations against pathogens. An effective method of protecting pea seeds from various diseases is wet treatment with bactericidal preparations with the simultaneous use of biologically active substances. To develop a device for processing seeds by wet method, research was conducted on the transport speed of immersion of spherical grains in liquid. When conducting practical experiments, we considered the movement in a liquid with a density of ρzh = 1000, 1090 and 1150 kg/m3 of individual pea grains of the Vita variety (spherical shape) with a moisture content of 14%. Sodium chloride salt (NaCl) was used to change the density ρzh of the liquid. To obtain more reliable information, the experiments were performed three times over. The temperature of the surrounding air and liquids of different densities was 20 °C. The data obtained were processed using one of the methods of variation statistics. It was found that in water (ρzh = 1000 kg/m3) the confidence interval of the transport speed of immersion of single grains with a reliability of, and in an aqueous solution of sodium chloride (NaCl) with a density of ρzh = 1090 and 1150 kg/m3, respectively, 0.10-0.28 m/s and 0.09-0.23 m/s. This approach to determining the transport speed of grain immersion in liquid can be used in the development of a machine for etching pea seeds using a wet method.
