PADC Unité Didactique de Pasteurisation, Contrôlée par Ordinateur (PC)

COMPUTER CONTROLLED TEACHING AUTONOMOUS PASTEURIZATION UNIT - PADC

SYSTEMES INNOVANTS

The Computer Controlled Teaching Autonomous Pasteurization Unit "PADC" receives cold milk from a refrigeration tank (not included). The milk is impelled with a milk pump (computer controlled). It is heated in the heat exchanger, by counter-current flow, with hot water coming from a circuit formed by a water tank with a heating element (computer controlled), a water pump (computer controlled), a manometer, a security valve, an expansion vessel, a purge valve and a pressure regulator, until reaching the established pasteurization temperature.

Description Générale

The Computer Controlled Teaching Autonomous Pasteurization Unit "PADC" receives cold milk from a refrigeration tank (not included). The milk is impelled with a milk pump (computer controlled). It is heated in the heat exchanger, by counter-current flow, with hot water coming from a circuit formed by a water tank with a heating element (computer controlled), a water pump (computer controlled), a manometer, a security valve, an expansion vessel, a purge valve and a pressure regulator, until reaching the established pasteurization temperature.

Milk is kept in a retention tank at the pasteurization temperature during a certain time. The temperature sensor situated at the retention tank outlet registers the temperature of the milk.

Then, instead of directing the pasteurised milk to the outlet, it flows in counter-current direction with the inlet milk. So, an effect is produced: energy saving when the inlet milk is heated.

A temperature sensor measures the milk temperature at the pneumatic valve (computer controlled) inlet. When the milk researches the pasteurization temperature, the pneumatic valve will open to extract the pasteurized milk.

A flow sensor is used to measure the milk flow at the milk pump outlet.

The process control is done from the computer using EDIBON control software. This software will allow an automatic control (PID) of the pneumatic valve with the pasteurized milk temperature.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
