1/2/2014 · The validation procedure encompasses many aspects with the process vessel and product both needing detailed study. In both cases it is important to find the cold zone at which the slowest heat transfer will be applied.Three phases of tests should be considered:• Temperature distribution – temperature mapping within a fully loaded process vessel to investigate performance against a control ...
A heat distribution study was performed in an industrial‐scale 4‐basket water cascading rotary retort under fully loaded operating conditions. Detailed analysis of the temperature distribution basket‐by‐basket was followed by an evaluation of the temperature distribution throughout the retort (at 0, 4 and 7 rpm).
Static steam retorts were one of the first types of retort systems used to process low acid canned food, saturated steam being an excellent medium for heat transfer. It is important in the operation of steam static retorts to remove air before starting the process as air pockets can create “cold spots”, this process is referred to as venting.
ABSTRACTA heat distribution study was performed in an industrial-scale 4-basket water cascading rotary retort under fully loaded operating conditions.
Heat distribution studies are therefore of crucial importance to ensure effective heat treatment of the food product. A heat distribution study is performed to study the uniformity in lethality throughout the retort, especially to identify the position in the retort that potentially results in lowest lethality.
The aim of this study was to determine the heat-penetration characteristics using stationary and rotary retorts to manufacture Kimchi soup. Both heat-penetration tests and computer simulation based on mathematical modeling were performed. The sterility was measured at …

Temperature distribution analysis of a water cascading retort in rotary and static modes Article in International Journal of Food Science & Technology 36(5):551 - 562 · June 2001 with 124 Reads
A typical temperature distribution test can use as many as 50 loggers per run. Most heat penetration and temperature distribution tests employ a data collection rate of one reading every 15-45 seconds. The frequency of these types of tests in retorts is variable but a good general average is …

A method employing transient heating was developed to determine surface heat transfer coefficients associated with steam/air mixtures in batch retorts. The method was based on instantaneous introduction of a highly conductive brick‐shaped test block of uniform initial temperature into a heating medium which was prestabilized at the desired ...

AGITATING RETORTS • Some retorts agitate the cans during processing in order to increase the rate of heat penetration into the cans. Agitation may either be axial or end over end. Agitation is useful for products which are too viscous to heat or cool by natural convection. By using agitation, the process time may be reduced by up to 80%.
