Control for pasteurization machines

The control for pasteurization processes allows for all the operations necessary for the pasteurization of dairy and similar products, being able to carry out a totally automatic or manual pasteurization process.

It is valid to work with different types of machines in accordance with the configuration stipulated by the manufacturer.

• Three temperature regulators/indicators are integrated in the control with the following functions:
• 1. A temperature regulator for the primary water circuit of the exchanger which can be configured to operate in:
  
  • A) A closed circuit which acts on the water heating resistors to achieve the programmed water temperature in the exchanger.
  • B) A closed circuit with water which comes from an industrial heater which acts on a servomotor which diverts part of the water flow to achieve the programmed water temperature in the exchanger.
• 2. A pasteurization temperature regulator which acts on a recirculation diverter valve.
• 3. An output temperature regulator which acts on a servomotor which diverts part of the flow of the cooling water to achieve the desired water temperature. in the case where this regulator is not used, the equipment will only indicate and inform of the exit 
• 4. It has a real time watch which will remain on time even if the power to the equipment is disconnected and will serve to print the reports with the time and date of the pasteurization result.
• 5. It has a rs232 communication to connect to either a printer or a computer to dump the pasteurization report data. in the case where it is connected to a computer, it can be controlled from that computer. for example to change instructions, start up, stop, etc.
• 6. It has a level logic input to electrodes or ptc to detect if the primary water circuit is not level and prevent break downs in case of overheating by electrical resistors when there is an insufficient level of water.
• 7. It has an input from a flow meter with a namur sensor to measure the flow and regulate it, acting on the regulator valve to control the retention time of the secondary milk circuit. to configure it, the input and the retention time control can be cancelled.
• 8. It has a 4/20 ma input for the same function as above.it can also be configured as a measurer and regulator of the milk circuit pressure. this input can be cancelled by configuration.
• 9. It has two 230 vac inputs. which come from the thermal circuit breakers of the milk pump and the thermal circuit breakers located in the resistors to detect break downs.
• 10. It has a buzzer and a relay to remotely activate a breakdown warning, in addition to a indicator light of anomalies in the system, in the case of signal anomalies, breakage of temperature probes, break downs in the printer or the thermal circuit breakers, etc... when an anomaly is detected it is also shown on the equipment display.
• 11. It has a button with a light to select the printing operations of the pasteurization report.
• 12. It has relay outputs to act on the valves for a totally automatic cleaning operation and the diversion of the milk. in the case of not using the outputs because a manual operation is desired, these outputs will not be operative and can be deactivated through the configuration.
• 13. It has three 2 wire pt100 inputs to control the temperature of the primary water circuit, the temperature of the secondary milk circuit and the temperature of the output cooling circuit. an optional printer can also be supplied.
