Hot Water Treatment or Hot Water Immersion or Dipped Hot Water Treatment, hereinafter referred to as hot water treatment, is a physical plant quarantine treatment using hot water to increase the temperature of the commodity to a certain level to be maintained for a certain time which effectively results in death (mortality) at all stages. Target pests. Preheating treatment bath: Preheating is done by activating the heat source so that the water temperature in the treatment bath can gradually increase. The water temperature is set 1 ° C higher than the treatment temperature level. • Putting commodities in the treatment bath: When the water temperature has exceeded 1 ° C from the desired treatment temperature level, the commodities that have been in the treatment container are put in the treatment bath. All commodities must be ensured that they are immersed in the hot water treatment bath and must not touch the walls or bottom of the treatment tub. Calculation of Temperature and Treatment Time (treatment Schedule): • Calculation of T0 starts when the thermocouple installed in the heating bath shows the desired treatment temperature level. • The expiration of the treatment time (TA) is the time that the treatment ends according to the desired time. • During the treatment time (from T0 to TA), the water temperature must be maintained constantly and should not experience a decrease. Hydrocooling: After the treatment is complete, the commodity must be immediately removed from the treatment bath to be placed in cold water. The purpose of cooling is to slowly reduce the temperature of the commodity until it is close to the normal temperature of the commodity before treatment.
