What Is Sous Vide Immersion Circulator- Step by Step Guides

Sous vide immersion circulators are electrical devices that are partially submerged in water baths to heat and circulate it, ensuring that the water remains at an exact and constant temperature throughout the process.

The Sous Vide Cooker circulates heated water inside the cooking vessel while also heating and circulating air to keep precise temperatures uniform. As an alternative to expensive sous vide machines, immersion circulators provide a simple and low-cost choice.

This article contains information on what a sous vide immersion circulator is and how it works. You will also find information on where it is commonly used. In addition, you will also find answers to some of the frequently asked questions. Go through the article keenly for a better understanding.

Steps on setting up sous vide immersion circulator when cooking

what is a sous vide immersion circulator

Step 1; Choosing a cooking container that is appropriate for the number and size of the food you are preparing is essential for success. This can be anything from a saucepan to a Dutch oven to a stockpot to a plastic tub.

Step 2; Sub-zero cookers are often mounted on a pot or plastic container’s side and clamped in place. While the Joule is a different sort of pot, it does not require a magnetic foundation and instead rests at the bottom of the pot and balances upright. To ensure that yours is properly positioned, it is recommended that you consult the handbook.

Step 3; completely immerse the sous vide cooker in a saucepan or container of warm water. Almost all sous vide cookers include a fill line that allows you to see how much fluid you need to use, so keep an eye out for that.

Step 4; Check to see that the immersed circulator is connected and that it is set to the proper cooking temperature (which can vary based on what you’re baking or roasting).

Step 5; As soon as the water reaches the correct temperature, remove the bagged food from the refrigerator and immerse it in the water (if you’re using a Ziploc bag, make sure to remove all of the air from it first). For added security, you can either attach the bag to the pot’s edge or use a weight to keep the bag heavier to ensure that it remains submerged during the process.

Step 6; Once the timer goes off, take your bag(s) from the pot, and you’re ready to serve and enjoy your properly prepared meal.

Components of a standard immersion circulator

Components of a standard immersion circulator

i. A thermometer is used to measure the temperature of the water

ii. Circulator motor or pump which keeps the water at a consistent temperature by moving it around

iii. A heating element usually heats the water up by going in it.

iv. An interface is used to set and view the temperature and the timer

v. Control circuitry in which it compares the water temperature to the temperature that you have selected for the gadget to heat to and powers the heat source as necessary to achieve the appropriate temperature

When using immersion circulators, the most important thing to remember is that they ensure that the water they’re immersed in is at the same temperature throughout the container. This is what makes immersion circulators so incredible.

It is for this reason that they are employed in sous vide cooking. Meat or veggies are placed in a vacuum-sealed bag, Ziploc, or even a canning jar, submerged in a water bath held by a separate pot, and cooked at a temperature regulated by the sous vide immersion circulator over an extended period.

Benefits of using a sous vide

Benefits of using a sous vide
  • Consistency

The fact that you cook the food at an exact temperature for a particular length of time means that the outcomes will be quite consistent.

  • Taste

Food cooks by absorbing its juices. This guarantees that the meal remains moist, juicy, and tender throughout the cooking process.

  • Flexibility

Traditional cooking can be time-consuming and necessitate your continual attention. Precision cooking is the process of bringing food to a precise temperature and keeping it there. There is no need to be concerned about overcooking.

  • Waste reduction

Food prepared traditionally dries out and spoils, resulting in waste. According to the USDA, traditionally cooked beef loses up to 40percent of its volume owing to drying out on average. Precision-cooked steak retains all of its volumes and retains its flavor.

Packaging of sous vide

Packaging of sous vide

Water evaporation is prevented, and the most effective transfer of energy from water to food is achieved by sealing foods. Put the seasoned meal in a plastic bag and squeeze out the air using the water immersion, a straw, or the vacuum sealing method.

To cook sous vide, you do not require a vacuum sealer. There are numerous alternatives; here are a few of the most effective types of sous vide packaging;

  • Sealable jars

Reseal-able bags are extremely adaptable, and they can be used in conjunction with the water evaporation technique to eliminate air from a bag without damaging it. For freezer bags, we recommend heavy-duty bags free of BPA, such as Ziploc’s freezer bags.

  • Reusable bags (silicon)

They make it simple to achieve the same high-quality results night after night.

  • Vacuum sealing bags

Although you are not required to purchase them, they are quite useful for batch cooking projects. Among the many excellent options are Food saver and Oliso, both of which are reasonably priced.

  • Canning jars

Glass canning jars can also be used to prepare a variety of various dishes. Beans and grains, and desserts such as biscuits and custards are also excellent for storing in jars of some sort.

Frequently Asked Question:

  • Why is an immersion circulator needed for sous vide?

Answer; cooking at a specific temperature for an extended time is made possible by immersion circulators, which heat and circulate water in a water bath to keep the water flowing continuously. This helps keep food soft and moist while almost eliminating the danger of accidentally overcooking or undercooking it.


Among sous vide machinery, the sous vide immersion circulator is distinctive in that it is a self-contained unit that both warms and circulates water to prepare food for sous vide. Additionally, it has the added benefit of being quite simple to use at home, making it an excellent choice for home cooking.

In conclusion, always be keen when purchasing sous vide. It is always advisable to purchase from a widely known shop and one that sells quality appliances. If you cannot identify some features in sous vide, seek help from a knowledgeable person.
