Abstract
Abstract Currently, frozen meat blocks are widely used in meat processing for production of sausages and other meat products. Efficient grinding of frozen raw meat is an urgent task for meat industry professionals. The V.M. Gorbatov All-Russian Meat Research Institute has developed energy- and resource-saving process for grinding of frozen meat blocks by milling. Determination of energy consumption for grinding of raw materials by multiple edge tools (milling tools) is the most important step in the creating of new type mincing machine.
Highlights
The process of raw material grinding is one of the most energy intensive processes in meat industry
Further details of power measurements will be regarded as a single statistical data sampling. This is due to the fact that the statistical analysis of power consumption should be performed for all cases of experimental grinding using the milling tool of the same type
On the basis of the central limit theorem [7, 8], the calculation results suggest that stochastic factors have equal influence on the energy consumption in the process of frozen meat blocks grinding by milling. As it can be seen from the results of statistical analysis of the experimental distribution of active power consumed by IBF-1 cutting mechanism drive motor in the process of grinding, there is a significant variance of values near the mean estimates for power
Summary
The process of raw material grinding is one of the most energy intensive processes in meat industry. The main area of research was the study of different design milling tools as a working element of mincing machine for frozen meat blocks. To justify such choice, the following factors may be used: 1) when grinding the raw material by milling tools the contact area of cutting edges with meat is minimal compared to the area of side surfaces of cutter knives, reduced power consumption may be achieved by friction and adhesion reduction; 2) when changing the parameters of raw material grinding process by milling and applying removable milling tools of different design and geometry, we can influence the formation of particle sizes of ground meat providing predetermined degree of raw materials grinding and increasing the quality of finished meat products; 3) when processing the frozen meat blocks of industrial sizes by one-stage milling, it is possible to shorten the traditional workflow of meat blocks processing (block cutting machine - mincing machine cutter), which will ensure resource-saving and reduction of energy consumption per one ton of product.
