Improvements in electronic control system for producing soft ice cream machines microprocessed Italian type

摘要

"Improvements in electronic control system for producing soft ice cream machines microprocessed Italian type".This patent improvements in electronic control system with microprocessor for machines producing ice cream Italian type or "mass ice cream cone".This system enables the monitoring, control and optimization of all stages of the production process, ensuring the high quality of ice cream produced by reducing the cycle time of production.And increasing the productivity of the machine.The novelty consists of a system of control and monitoring that provides for employment of a three-phase motor (5),Powered and controlled by a frequency inverter vector (12) which receives power single-phase or three-phase electrical network.This is inverter controlled by a microprocessor (13) existing in the electronic circuit control, said microprocessor controlling the entire machine.Said circuit is electrically connected to the sensors (14) level of syrup positioned in the two tanks (2) and valves (10) and (11) of the output of the mass,The circuit of the automatic actuation of the solenoid valve (15) controlling the passage of refrigerant gas by the coils (6) and (7),The inverter (12) which feeds the electric motor (5) for activation of Scouts (4),The motor (9) that drives the compressor (8) of the temperature sensors (21) arranged in the cylinder (3) and in the VATS (2) and a solenoid valve (22) positioned at a station (23) of the circuiTo put the refrigeration compressor (8) "by pass".The programming and control of the circuit made by means of a control panel (16) that has an alphanumeric display (17).A button "on / off" (18) and two function keys (19) and (20) identified by the symbols "+" and "-".Or any other characters that allow easy differentiation between both keys, press the "+" (19) allowing switching between the functions of "production", and "conservation".As well as the programming of the desired consistency for the mass.While the key "-" (20) serving to initiate the washing cycle (s) of the cylinder (s) (3) or indicate the quantity of ice cream extracted.
