Abstract

Reducing the cost of electricity consumed when cutting frozen raw materials in the meat processing industry can significantly improve profitability and other economic indicators. The possibility of energy saving in the innovative technology of one-stage fine grinding of food raw materials was studied. The selected frozen meat blocks (beef and pork) and collagen-containing raw materials (meat cuttings and tripe) were ground to the required degree usingan experimental IBF-1 grinder. At the same time, the active three-phase power consumed by the electric motor of the cutting mechanism drive was measured and recorded. The study results showed that the IBF-1 grinder (milling method) could replace three machines (frozen meat cutter, meat comminutor, and micro cutter) with sequential grinding in three stages according to the standard grinding technology. The calculations carried out on the power costs per ton of products confirm that grinding requires 2.6 times less than the total installed capacity of meatcutting machines of the standard technological chain.

Highlights

The researchobjective was to study the fundamental possibility of creating an energy-saving technology for one-stage fine grinding of food raw materials frozen in the form of blocks
As a result of reducing the standard process chain, usually used in the meat processing industry when cutting frozen raw materials, it is possible to achieve significant savings in the energy consumed for this process
Experimental studies have proved the possibility of one-stage fine grinding of blocks of frozen food raw materials to produce chips with dimensions that do not exceed 1 mm

Summary

Introduction

The researchobjective was to study the fundamental possibility of creating an energy-saving technology for one-stage fine grinding of food raw materials frozen in the form of blocks. As a result of reducing the standard process chain, usually used in the meat processing industry when cutting frozen raw materials, it is possible to achieve significant savings in the energy consumed for this process. This increases the economic performance of meat production. Reducing the equipment stock of meat-cutting machines (instead of three machines, one machine is used for fine grinding of frozen raw materials) will allow meatprocessing plants to direct the released funds to develop their production. The proposed technology can be used for grinding various frozen raw materials processed in the food industry
