Steam table temperature

Steam tables vary widely in their settings. Some have words like low-medium-high, some have ranges of 1 Low to 10 High while others may be 1 to 7. Still others have the actual temperatures.

The key question is not what setting you are using for your table, but what is the temperature of the food you are holding? Typically, hot food needs to be held above degrees Fahrenheit exact temperatures may vary by municipality.

The key is to use a good thermometer to frequently take the temperature of the hot held food and adjust the steam table accordingly. In addition, you need to stir frequently to distribute the heat and take readings at the top edge of the held food, rather than the bottom, which is closest to the heat source. If the extra moisture would not affect quality, using a lid on the steam table can help with even safe temperatures. Holding above the minimum temperature is fine as well but then you have to consider product quality issues.

Some foods like broth-based soups hold well on the maximum setting. These emerging chains are the growth vehicles to watch—the ones poised to be major industry players in the coming years.

Concepts to Watch New restaurants and soon-to-open concepts worth monitoring.Steam Table Tips for Restaurants A steam table is a wonderful appliance for a restaurant. It allows the chef to keep food warm and to serve large numbers of guests at any given time.

A few precautions will ensure that clients have the best experience possible. Cold food, food that has been sitting out too long and messy steam tables can chase customers away. Steam tables need water in order to do their job.

Always fill the compartments beneath the pans with the required amount of water. Check the water frequently as long as food is on the table.

It will evaporate over time. There should always be water in the compartment when the table is turned on. The temperature setting needs to be appropriate for the food items being served. If you set the temperature too high, the food will dry out.

Too low a setting could cause food related illnesses in the patrons. Any spills should be wiped off immediately to prevent food from sticking to the surface.

How to use Steam Table - Easiest Way

This will make clean-up easier after the steamer is ready to shut down. Make sure the unit is in good shape, dust free, and that all parts are secure. Always use caution when setting pans of food in the steamer. The food-holding pans can get very hot. Use hot pads or thick towels to protect your hands when moving pans out of the steam table.

After a pan is removed, hot steam will escape from beneath it. Make sure you and any patrons stay clear of the steam during this time. Small children should be closely supervised during the use of a steam table. The surfaces can also get very hot. When using a steam table at a public event, take care to secure all cords.

The cords can be a tripping hazard. They can be taped or placed under rugs. Renee Winship is a published author and has worked in the family restaurant and catering business and has also worked in a medical lab facility. She's an adoptive parent and has worked in daycare.

About the Author.Restaurant professionals know that bacteria responsible for food-borne illness can multiply by the thousands in very short period of time. They also know that you cannot tell always tell that this has happened by the smell or the appearance of the food.

Fresh chicken that was purchased in the morning and improperly stored can cause illness in the evening. This means that food that is hot or already cooked, needs to remain hot, and food that is cold, whether it is raw chicken or food that is eaten chilled, needs to stay cold.

Most pathogens that cause food-poisoning reproduce the fastest and thrive within a certain range.

How to Read a Steam Table

Even if they are not killed, they will, again, not reproduce. They will begin reproducing at an astonishing rate. Once present in high numbers, it is too late, the food is considered adulterated and not fit to serve. The image below, provided by the USDA, gives a graphic representation of the safe temperature zones for holding foods, as well as some minimal cooking temperatures for meats, poultry, and other foods.

Generally, cut-off time for foods in the danger zone, after which they are considered hopelessly adulterated and cannot be used, is four hours. This period is cumulative, however. This means that each time period during which food enters the danger zone is added to any other time period where the food is in the danger zone.

Most well-run kitchens do not flirt with the temps like this, if at all possible. Although certain foods like chicken, meat, fish, and dairy are especially hospitable environments for dangerous pathogens, all foods must be kept at proper temperatures.

It is easy for a busy kitchen to make mistakes in this area. For example, soups might be transferred from a large pot to a steam-table to keep warm. What if a cook allows the soup to cool down in the pot, dipping into the danger zone, and then pours lukewarm soup into a hotel pan on a steam table?

Steam tables are meant to keep warm food warm, not to heat cold foods up. The result, then, could be soup that inadvertently stays below even though it was judiciously placed in a steam table. So, foods should be properly heated up before being transferred. It would stand to reason that the same kind of thing goes for cold foods.

It's typically used to determine saturated steam temperature from steam pressure, or the opposite: pressure from saturated steam temperature. In addition to pressure and temperature, these tables usually include other related values such as specific enthalpy h and specific volume v.

The data found in a saturated steam table always refers to steam at a particular saturation point, also known as the boiling point. This is the point where water liquid and steam gas can coexist at the same temperature and pressure. Because H 2 O can be either liquid or gas at its saturation point, two sets of data are required: data for saturated water liquidwhich is typically marked with an "f" in subscript, and data for saturated steam gaswhich is typically marked using a "g" in subscript.

Heating processes using steam generally use the latent heat of evaporation H fg to heat the product. As seen in the table, this latent heat of evaporation is greatest at lower pressures. As saturated steam pressure rises, the latent heat of evaporation gradually decreases until it reaches 0 at supercritical pressure, i. Since saturated steam pressure and saturated steam temperature are directly related to one another, saturated steam tables are generally available in two different formats: based on pressure and based on temperature.

Both types contain the same data that is simply sorted differently. Saturated steam tables can also use two different types of pressure: absolute pressure and gauge pressure. Gauge pressure was created because it is often easier to reference measured pressure against the pressure we normally experience.

Steam tables based on gauge pressure indicate atmospheric pressure as 0, while steam tables based on absolute pressure indicate it as Also, to distinguish gauge pressure from absolute pressure, a "g" is typically added to the end of the pressure unit, for example kPaG or psig.

Values related to superheated steam cannot be obtained through a regular saturated steam table, but rather require the use of a Superheated Steam Table. This is because the temperature of superheated steam, unlike saturated steam, can vary considerably for a same pressure. In fact, the number of possible temperature-pressure combinations is so great that it would be virtually impossible to gather them all in a single table.

As a result, a large number of superheated steam tables use representative pressure-temperature values to form a summary table. Products Browse Products by Category.

Product Solutions.While most of our focus on steam table temperature is about keeping the product over the required minimum, too hot can definitely be a problem for product quality, especially for delicate foods like lean proteins fish, chicken breast, eggssauces that include dairy, which can break, and vegetables which can overcook. It is the temperature of the food that is important both for public health and for product quality.

Maintain temperature logs of hot held food frequently and stir to make sure product is evenly distributed. Beyond that, use foil risers to elevate the back of the hotel pan to allow some steam to escape or add cooler water in a pinch. But ultimately, if your steam table is consistently out of control, it is time to have it professionally repaired or invest in some new equipment.

Technical Documents.At atmospheric pressure - 0 bar gauge or absolute Therefore, at 0 bar gauge absolute Another kJ of energy is required to evaporate the 1 kg of water at o C to steam at o C. The total specific enthalpy of the steam or heat required to evaporate water to steam at atmospheric pressure and o C can be summarized as:.

Steam at atmospheric pressure is of limited practical use since it can not be conveyed by its own pressure along a steam pipe to the points of consumption. More heat energy is required to raise the temperature to the saturation point at 7 bar gauge than needed for water at atmospheric pressure.

From the table a value of The heat energy enthalpy of evaporation needed at 7 bar gauge to evaporate the water to steam is actually less than the heat energy required at atmospheric pressure. The specific enthalpy of evaporation decrease with steam pressure increase. Because the specific volume of steam decreases with increasing pressure, the amount of heat energy transferred in the same volume actually increases with steam pressure.

In other words the same pipe may transfer more energy with high pressure steam than with low pressure steam.
