PPM-DR : Portable pasteurization process monitor with digital recording (for immersion, shower, tunnel and steam pasteurizers)

The PPM-DR is a portable measuring device designed for recording temperature curves and for measuring the pasteurization effect (in pasteurizing units) during pasteurization of beer, cider, lemonades and soft drinks. The device can also be used as a recorder of any other temperatures in a defined time period, e.g. during mashing, main fermentation, post-fermentation, room temperatures in warehouses, etc.

It is possible to use the measuring device also for working calibration of immersion, shower, tunnel and steam pasteurizers to be used with different bottle/can formats and different drinks.

Delivery time : Usualy 6-9 weeks.

How the measuring takes place ?

The measuring device consists of two temperature probes and a measuring microcomputer. One temperature probe measures the temperature of the beer in a bottle or can. The second temperature probe controls the temperature of the shower water or water fog that heats the bottles.

The measuring microcomputer is located in a waterproof and temperature resist case. The length of the temperature probe is chosen so that the measurement point is at a height of approximately 10 mm to 30 mm from the bottom of the bottle or can, which is the place that heats up the slowest.

The pasteurization process monitor is equipped with an internal memory in which the measured temperatures are periodically stored. After the measurement, these measured temperatures are transferred via the RS232 or USB connection cable from the internal memory of the pasteurization monitor to the PC or the notebook, where the measured values ​​are processed and evaluated using the supplied evaluation software.

The pasteurization process monitor is powered by a 3.6 V lithium battery (size AA), which is easily replaceable. The measurement is switched on and off by placing a magnet on the case of the pasteurization monitor, or the pasteurization monitor can be switched on and off software-wise from the PC.
