Pasteurization substrate in the classical way .

After filling the substrate racks or the containers with the substrate in the chamber pasteurization room cleaned of particulate substrate, wash the floor and to control temperature set remote thermometers . The enclosure doors closed and the heating system, the steam and air handling unit at full recyclingair . When the automatic control system of microclimate parameters Connect only temperature sensors, humidity sensor to prevent it from damage for a period of pasteurization in the chamber is not set .

After the supply of steam into the chamber temperature rises to 55 - 56 ° C for 2 - 3 h . In this case, the chamber should not be formed with different temperature zones, which ensures a sufficiently strong airflow usingventilation unit .

It is important that during the pasteurization temperature was no difference in the substratedifferent camera locations, particularly between the upper and lower tiers of shelves or containers . For this purpose, ensure constant air circulation in sufficient pasteurization chamber. The need for supplying fresh air for ventilation, is usually absent. However, if there is a risk of sharp raising the temperature of the substrate, thenit is advisable to carry out periodic venting chamber to reduce the temperature and eliminate hot spots. Short-term rise in temperature of the substrate to 62 - 63 ° C (within 1 h) is acceptable and does not cause negative consequences .

When the substrate temperature decreases to 55 - 56 ° C pasteurization process ends and begins the second stage of the thermal treatment of the substrate - the period C .
