STOCK is a leading provider of retort and in-container sterilization solutions for the North American food processing industry, offering a full range of equipment, systems, and services to produce shelf-stable … the water drop "swimming" … Water steam spray batch retort sterilization process machine : high pressure circulation water spray into the overpressure autoclave chamber to make small water drop. Aseptic Processing employs a sterilization step with product specific temperatures around 190ºF/88ºC to achieve minimum hold tube lethality. fh The time for the heat penetration curve to traverse one log cycle. A method for manufacturing retort-pouch rice is described. Figure: 8.6 process and the attainment of commercial sterility”. It held 6 baskets of product. Retort machine is a pressure vessel used to commercially sterilize food after it has been packed into a container and the container has been hermetically sealed. Newer agitation retort processes have reduced cooking times, resulting in energy savings and less degradation of the … Food sterilization package material : The package material should be heat resistant material, heat resistant range was at 130°C ( 265°F) , over 25mins, the container can't be out of shape and could not have any chemical precipitation. small water drop absorb thermal from injection steam immediately. Retort sterilization provides an effective means of achieving optimum shelf stability and can be done with fairly simple equipment. millions of small water drop surround the product and heating it. Retort sterilization, also known as canning, is a well established thermal process for in package sterilization of low acid food products. Aseptic Processing. Typically, the sterilization temperatures vary from 110°C to 135°C. The method makes it possible to implement a production process using an assembly line and increases production efficiency by reducing the amount of time taken by a preprocess prior to a retort sterilization process. In this case, F the total lethality or sterilization value of the process, would equal 6.3. The dotted line traced parallel to the descending line encloses an area corresponding to the retort process had the steam been turned off after 25.5 min (vertical dotted line). In this process, the package is sterile, the environment is sterile, … The method is characterized in that: uncooked rice is … Critical factors may include physical and chemical aspects/parameters associated with the container, the product, the retort and processing conditions. Each basket held 6 layers of cans. Aseptic and retort are two of the main processes. The F value\**\ for a process is the number of minutes required to kill a known population of microorganisms in a given food under specified conditions. The Saturated Steam Process is the oldest method of in-container sterilization. Also referred to as Optimizing Sterilization Process of Canned Food Using Temperature Distribution Studies www.iosrjournals.org 28 | Page 2.1.2 Retort B (Water Spray) The retort was about 6-m long and about 1.2-m in diameter. Since air is considered an insulating medium, saturating the retort vessel with steam is a requirement of the process. The fill temperature is near ambient. How to do the high temperature sterilization process.
