Applications for Steam in the Food and Beverage Industry

1 Applications for Steam in the We work well under pressure. food and Beverage Industry Steam AS A MEANS OF generator, the number of BTUs per DELIVERING HEAT hour directly equates to the number of kilowatts consumed. This in turn Dry saturated Steam , generated by an directly equates to the boiler electric Steam generator, contains no horsepower . As an example, a 10kw boiler additives and provides a clean Steam generator is rated at or and effective way of delivering heat to boiler horsepower. It is rated to surfaces it contacts. In contrast to hot produce lbs. per hr. of Steam water which gives up its heat by which equates to 33,500 BTUs per absorption, an inherently slow process, hour.

2 The water consumption Steam delivers heat through the very necessary to produce this amount of rapid process of condensation. With Steam is only hr. (Note: sufficient time and temperature, and boilers and Steam generators are rated the moisture derived from the on the basis of using 212 F feed 16400 Swash Steam Generator condensation process, heat destroys water. Lower feed water temperatures the proteins which form the cells of reduce the Steam output accordingly. ABOUT ARS/PRESSURE the microbes and can result in It is not recommended that feed water WASHER COMPANY sterilization of the surfaces in contact be greater than 140 F unless the feed with the Steam or, in the case of water pump is designed for hot water porous materials, the material itself.)

3 Use.) These calculations are directly ARS was established in 1971 to proportional, so a 20kw Steam provide sterilizing and washing generator puts out exactly twice the The heat required to cause a volume equipment and field amount of Steam and heat as a 10kw of water to be converted into Steam at maintenance and repair services unit and consumes exactly twice the the same temperature is call the latent to food and Beverage firms, gallons of water per hour. heat of vaporization. When Steam hospitals, laboratories and Furthermore, at a given voltage, the comes into contact with a surface pharmaceutical or medical amperage draw of a 20kw Steam having a lower temperature, it virtually device manufacturers.

4 Our generator is exactly double that of a instantly condenses and all the latent equipment and service have 10kw unit. heat is absorbed into the material it earned us an outstanding touches. As a result, a surface can be reputation among our Electric Steam generators are heated far more efficiently with 212 F. customers who have come to extremely efficient and safe. Steam than with 212 F water. The rely on ARS. Approximately 98% of the energy pressurized chamber of an electric Steam generator efficiently produces from the heating elements is Our philosophy is to provide converted to Steam with very little dependable equipment 97% dry saturated Steam and delivers significantly greater amounts of heat heat loss into the room.

5 Heat up time incorporating high quality is typically not more than 10 minutes. components. The ARS team is than can be achieved with hot water heaters in far less time and with These units are completely safe for dedicated to the highest indoor use because there is no open standards of workmanship. Our significantly lower water consumption. flame, no fumes, no combustible fuel pride rests on your satisfaction and no fuel storage as is the case with The amount of heat delivered by a with the products and service natural gas or diesel fired boilers or Steam generator is expressed as BTUs we provide. We believe that with pressure washers. Various in thousands per hour which is ARS you can achieve many years configurations are available for fixed, directly derived from the number of of reliable performance and an centralized installations or with wheels pounds of dry saturated Steam overall low cost of ownership.

BOTTLING LINE STERILIZATION that the process be continued for at residual wine in the pores of the wood WITH Steam least 15 minutes after achieving is extracted. The flow of residual wine approximately 212 F. If the bottling from the pores of the wood into the Steam is the most effective means of line is to be used immediately, it is inner space of the barrel is thought to achieving sterilization of a bottling recommended that it be cooled with help pull or loosen the tartrate crystals line. Taking advantage of the latent clean tap water.

7 From the surface of the wood. In the heat of vaporization, Steam , because it event there is a leak in the barrel, this is a gas, distributes heat everywhere in USE OF Steam WITH vacuum will not form. By removing the the bottling line. As it contacts the OAK BARRELS bung after a few minutes, it is easy to colder surfaces, it condenses and gives determine if a vacuum is present or up its heat. When sufficient heat is Tartrates which deposit on the inside not. As a result, cleaning a barrel with delivered, sterilization can be surface of wine barrels are typically Steam provides a built-in, convenient accomplished. In addition to the much removed by melting and rinsing. When leak test. Since this leak test is greater efficiency in delivering heat hot water is used, the typical conducted with a gas versus a liquid, it compared to hot water, Steam can temperature delivered to the barrel is is more effective in detecting leaks.

8 Effectively deliver heat into nooks and rarely above 180 F. In comparison, Critics of Steam in barrels often say crannies where it is difficult to get when Steam is utilized, the that the heat will volatilize certain liquid water, ozonated or not, to go. temperature inside the barrel reaches compounds in the oak which impart Most in-line filters are also rated for 212 F. As a result, substantially more flavor to the wine. In an unpublished Steam sterilization. (Check with the heat is available to melt the tartrates. study conducted at ARS/Pressure supplier.) As a result, the entire In addition, the latent heat of Washer Company, thermocouples bottling line from filter to filler spout, vaporization delivers additional heat were embedded at varying depths in can be sterilized with Steam .

9 Making the process even more the staves and at locations around the effective. When sterilizing a bottling line, barrel. A thermocouple was also especially with in-line filters, it is very placed in the Steam wand and one important to lower the output was suspended in the barrel. The pressure of the Steam generator to not temperature inside the Steam wand more than 25 psi. An FDA and NSF- was slightly higher than 212 F due to approved Steam hose rated at 100 psi back pressure in the wand. In the open and 300 F is recommended with space of the barrel, the temperature suitable fittings to attach one end to was the expected 212 F of the Steam generator and the other to atmospheric Steam .

10 However, oak is the sanitary input of the filter housing such an effective insulator that at a or bottling line. All the filler spouts depth of only 1/8 into the wood from should be open. It is recommended Bordeaux Style Wine Barrel Steam Wand the inside of the barrel, after 20. that the Steam output valve be minutes of steaming, the temperature opened part way until it is evident Because Steam is a gas, it can also was only 90 F. At this temperature or from dripping condensate, that Steam penetrate the pores of the wood more less, it is unlikely that flavor enhancing has passed through the filters. Once effectively than water. In the process compounds would be volatilized. flow has been established, the valve of penetrating the wood, it is When steaming barrels, it is critically can be opened all the way.
