2/19/2024 0 Comments Calculate pasteurization units![]() Some DSFT spreadsheets also calculate the concentration of chemical compounds produced as a result of high temperature processing known as thermal process indicators or TTI. Spores of this variant have a Z-value of 10 ℃, and a Tref of 121.1 ℃. The non-proteolytic variant that grows at low temperatures produces spores of relatively low resistance to heat whereas the variant concerned with canning low acid food such as meats and vegetables, produces much more heat resistant spores. Clostridium botulinum has two variants that must be considered differently in heat treatment processes. The organism is designated by its Z-value and its reference temperature, Tref. This is usually a bacterium or spore, selected because it is a pathogen or spoilage organism. Note I am not providing a guide to using spreadsheets but basic information that a competent Excel user should be able to use to make their own thermal processing spreadsheet.ĭownload Excel Thermal Processing Spreadsheets.Īll thermal process calculations start with a target microorganism. Here we provide an overview of the background, including a summary of the underlying mathematics, required to produce an Excel spreadsheet for performing basic thermal processing calculations. This section provides the context to using Excel to calculate the cumulative lethal effects (at all stages during processing) of heat on microorganisms and provides an explanation of how the Excel spreadsheets and On Line calculators available for download from the Dairy Science and Food Technology (DSFT) work. This is why in the food and beverage industries, it’s essential to use equipment specifically designed for the product you’re treating.MICROSOFT EXCEL LETHAL RATE CALCULATORS AND TEMPERATURE TIME INTEGRATORS FOR THERMAL PROCESSES Introduction Energy transmissions typically occur through continuous water spray, steam, or hot water baths.įlavor deterioration is one of the biggest problems with pasteurization. It’s critical that the equipment remains hygienic, safe, easy to maintain, and has a legitimate warranty. Food products can be heated either directly or indirectly by internal or external heat exchangers. With so many options, there’s sure to be tunnel pasteurization equipment that can fit your exact needs.ĭimensions and technical design depend entirely on the product, container, and required output. They are available in various sizes, dimensions, and technical specifications. Request A Tunnel Pasteurizer Quote Today CUSTOMIZED AND EASY TO OPERATEĪ tunnel pasteurizer is a great solution to providing a simple yet reliable alternative to flash pasteurization units. They are typically sprayed with cold water that returns them to the desired temperature.Īt SMT, we’re a tunnel pasteurizer manufacturer that provides commercial-grade equipment for improved hygiene levels and competitive production rates. The products then enter a cooling chamber before exiting the machine. Products enter the pasteurizing chamber on a conveyor belt system and are heated with water or steam to kill pathogenic bacteria and inhibit enzymes. Tunnel pasteurizers are a large part of the manufacturing process for food and beverage items. Request A Tunnel Pasteurizer Quote Today COMMERCIAL-GRADE EQUIPMENT Preserves freshness & enhances shelf life.Efficient & effective process of keeping products safe for consumption.Halts the growth of yeast & reduces the spread of diseases.Kills microorganisms & pathogenic bacteria such as Salmonella, E.Our machines are durable, reliable, and adhere to the highest hygiene standards. We can manufacture our equipment in any size or dimension with technical specifications that fit the exact needs of your production line and products. A tunnel pasteurizer consists of large chambers or cabinets constructed out of food-grade stainless steel and other high-quality parts.īusinesses that package consumable products in glass jars, bottles, or cans use tunnel pasteurization to increase product safety and prolong shelf life. Smart Machine Technologies custom-builds food and beverage tunnel pasteurizers for improved flavor, safety, and easy integration into your manufacturing process.
