Embodiment Construction

[0031] Embodiments of the present disclosure relate to an improved steam-water spray (SWS) distillation system that provides more uniform processing and faster cooling than prior art systems. In this regard, the improved SWS distillation system is configured to increase the total fluid flow through the still and thus reduce the temperature differential across the load during the cooling phase.

[0032] In general, embodiments of the improved SWS distillation system are achieved by separating the heat exchanger from the main recycle fluid loop and using a separate pump to circulate the process fluid through the heat exchanger. It will be understood from the following description that the advantages of the improved SWS distillation system include at least the following points: no increase in the height of the still; more flexibility in the selection of heat exchangers; the flow rate in the cooling stage can be compared with The flow is the same during the start-up phase and the ...

Abstract

A recirculation circuit for a processing vessel is configured to process a load with a process fluid. The recirculation circuit includes a first circuit portion configured to recirculate a first portion of the process fluid through the vessel. The first circuit portion includes a first pump having a first flow rate and a first output pressure and a heat exchanger in fluid communication with the first pump. A second circuit portion is configured to recirculate a second portion of the process fluid through the vessel. The second circuit portion includes a second pump having a second flow rate higher than the first flow rate and a second output pressure lower than the first output pressure.

Description

Background technique [0001] Overpressure retorts are used for in-container preservation of food products, such as for pasteurization or commercial sterilization treatments (hereinafter sometimes collectively referred to as "load treatment", "treatment load" or similar treatments). Typically, these machines use a combination of pressure and temperature according to a predetermined schedule to commercially sterilize packaged food. [0002] Additional overpressure for handling food containers can be achieved in jet stills where container water or another suitable process fluid (hereinafter "process fluid") is pumped from the top (and optionally also from the sides) of the container ) spray the load through the container. The water can be heated by external means, or alternatively, steam can be injected directly into the container. [0003] figure 1 A prior art steam-water spray (SWS) distillation system 10 is illustrated. Prior art SWS distillation systems 10 typically use di...
