Abstract

It is noted that the materials for contact with the product must meet a number of requirements, namely: be inert to the product in operating conditions, including changes in temperature and pressure, be corrosion resistant, non-toxic, mechanically stable, smooth, easy to clean, and the conditions are not affected on the surface of use. It is believed that the main operations of the processing and food industries are cleaning, sorting, drying, grinding, heat treatment of products. Physical, mechanical, frictional, aero- and hydrodynamic, electrical and optical properties of materials play an important role in the contact of equipment with grains, fruits and vegetables. It is stated that most often in the process of designing and manufacturing equipment for the food industry, stainless steel is used due to corrosion resistance and durability of the material.A comprehensive study was conducted, including analysis of physical properties of fruits and vegetables (size, shape, weight, color, density), accounting for properties, application of modern technical means in the design of equipment for sorting fruit and vegetable raw materials, which provides efficient and high-quality sorting fruit and vegetable raw materials. The generalized structure of the system of visual control of the flow of apples on the conveyor belt with the use of a video camera is considered. The results of the study were interpreted, namely the calculated distance between the lens of the installed video camera to the surface of fruit and vegetable raw materials on the conveyor belt 3000 mm, the total size of the controlled section of apple flow on the conveyor is 1112,03 × 843,25 mm, the area corresponding to one pixel, is 1,07 × 0,82 mm. The size of the point of the controlled area is sufficient in this case. At the same time, it is expedient to increase the size of the section of the apple stream due to the location of the video camera so that its optical axis is located at an acute angle to the plane of the conveyor belt. The specified location of the video camera allows you to increase the size of the controlled area of the flow of apples (1400–1800 mm) × 1700 mm.
