The grinding process of fruits and vegetables in the preparation of juice with pulp, usually carried out by means juicers, blenders or grinders with a relatively slowly rotating blades and stationary gratings with a continuous flow of raw materials. Intensification of processes of division of the products of the conversion will asunder allow sharply duration and raise the uniformity of the processing cheese that will say on quality ready drink as a whole. The interaction of the blade and material is characterized effort of the cutting moreover the general power, acting on blade on the part of material, is not found in planes of the cutting in consequence of which on blade of the knife, alongside with vertical, acts and horizontal forming power. Horizontal form to deform (change) sidebar cut-ting edge of the knife in consequence of which in general event provision to necessary acerbity in flat material requires increase of his(its) thickness and using the additional relationships (the jumper). It is installed that values of magnitude of deformation and speed of its extending are connected among themselves through the parameters characterizing pressure and plasticity of medium of installation of machining. Hence, speed depends on properties of a body in which the pulse is passed round. In the majority of materials speed of extending of a pulse appears an order of 5 103 km/s. Accounting of received data in the determination of rational cutting speeds for different materials with elastoplastic properties (approximation cutting speed for the propagation velocity of deformation) will allow to reduce pre-separation deformation and, respectively, spent on her work, localization stress under cutting edge, and, as consequence will lead to higher product yield and improve the purity of the slices. Improving the quality cutting may be associated with an increase of inertia of the structural elements of the material (fibers) by increasing the speed of the process.
