PASTEURIZATION MONITOR PM-4
The Ecklund-Harrison Pasteurization Monitor 4 (PM-4) is the next generation beer and beverage pasteurization monitoring computer. The unit needs no field calibration or charging of the battery. The PM-4 offers the utmost in ease of use and reliability today.
The PM-4 is housed in a waterproof NEMA rated enclosure. The window in the housing cover allows for the display of operational data, this gives the user immediate results of the product run without having to interface to a computer. A water tight electrical connector allows for the attachment of an interchangeable precision RTD temperature probe. The PM-4 communicates with a computer using an infra red reader attached to a serial or USB port.
The PM-4 utilizes extremely low power components and operates with a very high amperage hour rated internal battery. The unit will operate hundreds of hours before battery replacement is needed and travels with the product through the tunnel pasteurizer. A product container (can or bottle) is placed in the sample basket and the temperature of the cold spot is monitored with a precision RTD temperature probe attached to the PM-4. A second precision RTD temperature probe monitors the ambient spray temperature. Product temperature, as a function of time, is measured and used to calculate pasteurization units (PUs). Spray and product temperature, maximum cold spot temperature, and elapsed time are all recorded and saved in memory.
To store a permanent record of the product run, the PM-4 may be interfaced to a Windows based computer using the optional IR reader. The Windows compatible software provides the capability to store data, produce screen displays, print graphs, recall the graphs and detailed summaries for analysis and printing.
*A PU derived from the Lethal Rate Curve, is logarithmically a function of time and temperature. One PU will be delivered if 140 degrees F (60 Degrees C) is maintained for one minute. PU’s change with temperature by an order of magnitude (x10) for each 12.5 Degree F (6.9 Degree C) change in temperature and increase with increasing temperature.
PM-4 FEATURES:
- Automatic internal self calibration eliminates manual calibration errors.
- Run data is stored in database format enabling a user familiar with Microsoft Access to produce custom reports.
- The Z factor is software changeable.
- Probes from earlier pasteurization monitors may be used with the PM-4.
- Communication with a PC is accomplished by IR (Infra Red).
- Internal battery never needs recharging (annual replacement required).
- Real time clock.
- Date and time stamp on printouts.
- Fahrenheit or Celsius temperature measurement is software changeable.
- LED light blinks during sampling to assure operator the unit is in RUN mode.
- TAT (time above temperature) threshold is software changeable.
- PM-4 interface software is compatible with all Microsoft Windows platforms.
On-board liquid crystal display permits the operator to immediately view:
- Starting product and spray temperatures.
- Maximum product and spray temperatures.
- Total run time.
- Total pasteurization units accumulated.
- TAT (time above temperature).
- Final process temperature.
