In the conditions of the global economy, food industry products have a good share in international trade. It is primarily ready-made food products that are ready for use. The basic problem that needs to be solved is the safety and quality of food products. Machine “Planetary mixer” is used for mixing and preparing dough. From the aspect of optimal fulfilment of the working function of the preparing dough “Planetary mixer” has to fulfil the following conditions: - the complete space in which the dough is located must be treated equally with the mixer; - noise and vibration reduction should be ensured and appropriate precision positioning of the machinery’s executive bodies; - a compact construction of the drive system is required with the optimum utilization of the available resources. In the paper is presented technical design solution of the drive system for machine based on the demands of regional medium size enterprise and therefore it is limited to the requirements of the investor. The final solution was achieved by using the modern methods of product development.

The sensitivity analysis could be defined as a study of how the variability of the output parameter of the considered model can be distributed to its sources, actually, on the variability of the various input model parameters. It helps to identify the most important design parameters of a particular structure and to focus on them during the design and optimization process. This paper is focused on the application of stochastic sensitivity analysis of maximum equivalent stress and maximum mid-span deflection of timber-concrete composite beam. All input parameters were considered to be random variables. Latin Hypercube Sampling numerical simulation method was employed. The estimation of the sensitivity was derived from Spearman rank-order correlation coefficient.
