CFU: 
CFU subdivision: Lectures: 4
Basic aims:  To know the basic technologies underlying the mechanized agricultural processes. To analyze and quantify the main parameters of agricultural processes at farm scale.
To provide the basic methodology and the interpretation key for the application of the advanced information technogies in the production contexts of the agri-environmental enterprises; this even underlying the related interactions with the farm machinery set.
Acquired skills:  To identify and describe the principles behind the technologies used in mechanized agricultural processes. To assess, analyze and quantify the characteristic parameters of plants and machinery for the agricultural processes in function of specific needs. To set and solve simple numerical logistics problems at farm scale.
To evaluate technical performances of the different components of an information system to be used within an agricultural context. Practical skillness in the integrated use of GIS and GPS technologies for farm management purposes. Acquisition of a information-oriented competence to design and manage an information system.
Course contents:  Functions, working principles and architecture of
machines and plants used in agricultural processes
Energy forms and technologies used
Fundamental farm processes
Elements of logistics for the farm
Program:  Function of machines and equipment in agricultural
processes: manage and use energy for production,
handling, storage and primary processing of
agricultural products

Froms of energy and technologies underlying the
mechanized agricultural processes:
-Mechanical Energy: overview of mechanical
parameters and main equations
Basic technologies: review of internal combustion
engine, transmissions of motion, efficiency
-Hydraulic Energy: overview of hydraulic parameters
and main equations
Basic technologies: pumps, blowers and compressors,
valves, actuators, yields, in the hydraulic circuit
machines and installations
-Electricity: Overview of electrical parameters and
main equations
Basic technologies: the electric motor, the electrical
business, design and security, returns
Thermal-Energy: overview of thermal parameters and
main equations
Basic technologies: fuels, boilers and heat exchangers,
heat transport

Basic agricultural processes:
-Handling of liquids (water, milk, manure), self-
propelled irrigation systems, spraying of liquids
-Handling of solids (grain, etc.), mechanical actions on
the solid products (grinding, cutting)
-Heating and cooling of the fluids and solids,
pasteurization
-Drying

Elements of logistics for the farm:
-Optimization of chains of mechanization
-Transportation chains of harvested produce
- Farm capacity storage
-Indicators of overall efficiency of the farm system
Prerequisites:  Fundamentals of agricultural processes
