Introduction

This course design describes the method of technological calculations of the test kneading machine, which include calculations confirming the operability of the designed design of the machine, as well as technoeconomic calculations confirming the feasibility of this improvement. Also presented is a modernized line with the possibility of producing rye bread, in the process of preparation of which the designed machine is involved.

6.1.3 Psychophysiological Factors

The main psychophysiological factor in the production of bread is the monotonicity of labor (stacker of finished products, mold lubricant).

Work performed: placing finished products on container trays, lubricating molds and gouging burnt loaves of bread.

Monotonous work, monotonous techniques in work (laying bread) lead to noticeable fatigue, violation of various functions of the body. The consequences of this are increased morbidity, injuries. Production gymnastics is an effective means of eliminating the consequences of monotonous movements.

In the future, it is worth thinking about the issue of mechanization and automation of these technological operations.

Conclusion

In this term paper the description of dough mixing cars of a design of I8HTA12 is given; The scope of its application in the flow line is indicated; correct installation and maintenance, design, operating principle and technical characteristics are considered.

The performance calculations are given. And also modernization of the dough mixing I8HTA12 unit - for more effective work the shnekovy pumps were replaced by rotor. Also on this unit there was an opportunity to produce rye bread.

As a result of the studies, it was found that the dough kneading machine used in food production is a highly efficient technological equipment that significantly increases labor productivity.
