Temperature-indicating device Mercury-in-glass MIG thermometer or equivalent: Analyse Using our new visualization tools you can analyse your search results easily browse CABI data. Methodologies to study convective heat transfer to foods are explained. Manual for short course on recent trends in packaging of meat and meat products.
In the absence of a maintenance system, each retort should be tested every two years under the worst-case scenario. Diagrams of loading patterns and sensor placement are recommended. This misconception likely occurs because they see the weld bead widen out with more voltage and become narrow and ropey with less voltage as illustrated in Figure 8. Factors affecting calibration include: Thermocouples should be calibrated against a traceable calibration standard thermometer, RTD , thermistor.
Texture scores of in-pouch processed product were comparable to that of conventional kheer. It has a spelling or grammar mistake. This is an area where the knowledge and experience of the specialist supervising the study are of upmost importance. A detailed diagram identifying all equipment for which the use of steam is required including the numbering system used to identify each retort and the steam supply line arrangement should be made as prescribed in this section. F represents the time intercept from a thermal-death time curve log t gm vs T at T ' Tx. Browse and filtering tools You can browse through authors topics. Note however that every electrode diameter has a maximum current density before the welding arc becomes very unstable and erratic.
While F o value was obtained from the software used along with the data logger, the following formula was employed to calculate the sterilization time U defined as the equivalent, in minutes at retort temperature, of all lethal heat received during the process at Some products such as vegetables vacuum-packed in cans may have a minimum vacuum as a critical control point. The devices should be capable of simultaneous data generation within pre-established time intervals in order to permit determination of the slowest and fastest heating zones in the chamber. For example, the use of thermocouple wire from the same spool is recommended to make all thermocouple leads and extensions. Studies on methods of preparation and preservation of kheer. The kheer mix comprising of rice and sugar, subjected to thermal processing could be considered as essentially a liquid product and the mode of heating could be said to be convective.
