The Republic of Uzbekistan is one of the leading regions for the production of gourds - especially the most valuable varieties of melons. The nutritional value is primarily due to the high sugar content, and the taste value is due to the sucrose content. Summer grades with a sugar content of 12 … 19% are considered the most sugary. The sucrose content is 60 … 80%, but these varieties for long-distance transportation are practically unsuitable, so they are used in growing areas. It has been established that in non-waste processing from 1 ton of melon fruit it is possible to obtain: melon jam - 155…165 kg or concentrated melon juice (“honey”) – 65 … 70 kg or dried (dried) melon – 70…75 kg; vegetable oil from seeds – 2.5…3 kg; protein flour from the peel – 20…23 kg. The article presents the results of a study of the physicomechanical properties of melon fruits as an object of technical processing of peel, pulp, and seeds. To conduct studies of the physicomechanical properties of melon fruits, a methodology for experimental research has been developed.

In the paper provided efficiency analysis different types of feed processing with purpose decreasing energy use in cutting stalk crops and creating appropriate cutting units, also study results in assescment energy use in cutting with a rectangular knife and received formulation cutting strength change, the results of a change of knife for case in cutting of prebend stalk of various sizes. Results of theoretical research of catting work, the tensile stress of the upper fiber, stresses on the blade of the knife which is necessary for the destruction of the fiber. The use of pre-bending during the cutting of cutter material reduces the cutting work in comparison with the cutting work is 201.12 N cm this is compared to the chopping 290 N cm reduces cutting performance by 35.05 percent.

The paper presents the results of a study in the kinematics and dynamics of a multi-blade disc cutting device. In the advanced hardware scheme, the clipping process is performed as punches. We have a straight blade edge rotated 200 degrees back from the radial direction. As a result, the sliding motion process is reduced and the trunk is easily cut. For this reason, it is advisable to reduce the sliding process when cutting a hard stem, and it is preferable that the blade be made in the form of a hyperbolic spiral, and not an Archimedes spiral, the curvature of which is directed towards the stem, and not in a straight line. Kinematic and dynamic studies performed on a multi-knife disk shearing device accelerate the technological process of the device, increase the pressure of the blade on the trunk, and make it possible to cut it intensively.

The paper presents the results of the analysis of the process of cutting the stem with a disk-shaped knife, taking into account the physical and mechanical properties of stalk feed. The shell of corn stalks grown in the hot climate of our country is thicker and harder, and its coefficient of friction is somewhat lower. The smaller the angle of friction, the more difficult it is to clamp such a rigid piece of rod between the active and fixed blades. To avoid this condition, the stem must be pinched and sheared between the active blade and the passive blade. On the basis of kinematic studies, the conditions for ensuring the sliding of the rod along the blade of the grinding knife are determined in the work. Based on the physical and mechanical properties of corn stalks, the conditions for ensuring the sliding movement of the stalk along the chopper knife blade are considered.
