Water temperature parameters of plug kettle

Practical parameters of water temperature

High temperature steaming / boiling with hot water: 88 ℃ ~ 94 ℃, suitable for shallow to medium baking

Plug straight into the upper pot: boiling water temperature range, 88 ℃ ~ 94 ℃

The upper pot is inserted diagonally and then straight: boiling water temperature range, 90 ℃ ~ 95 ℃

If you boil the baked beans in high temperature, you can add some cold water in the pot so as not to be too bitter.

* the final extraction water temperature of high-temperature soaking should not exceed 94 ℃, which can restrain the bitterness.

Low temperature bubble boil / pot heated with raw cold water: 86 ℃ ~ 92 ℃, suitable for medium and deep baking to re-baking

Straight into the upper pot: the water temperature is 82 ℃ ~ 90 ℃.

After oblique insertion of the upper pot, the water temperature is 84 ℃ ~ 92 ℃.

* the final extraction water temperature of low temperature bubble cooking should not exceed 92 ℃.

Cold water is put into the pot to create a low temperature extraction environment.

Heating the pot with hot water helps to create a high temperature extraction environment with 70% boiling time above 90 ℃; if the pot is heated with unboiled cold water, it helps to create 50% low temperature extraction environment with boiling time less than 90 ℃.

In principle, deep-baked beans or beans with low density and easy to increase the extraction rate should be extracted at low temperature, that is, heating the pot with unboiled cold water, there will be a better taste spectrum. Beans baked in shallow medium or with high density, which are not easy to increase the extraction rate, should be extracted at high temperature, that is, the pot should be heated with hot water, and the taste spectrum is more charming.

Hot water is put into the pot to create a high temperature extraction environment.

If more than 90 ℃ of hot water into the next pot, fire heating, do not need more than 10 seconds, hot water will rise into the pot, it is best to adjust the firepower to medium-sized fire, this practice is easy to lock the extraction water temperature in 90 ℃ to 94 ℃, the water temperature is obviously higher than raw cold water heating, avoid using fire, lest the water temperature soars to 94 ℃, easy to extract high molecular weight bitter substances.

Basically, when the pot is heated with hot water and the firepower is properly controlled, the temperature of the final extraction water will be 2 ℃ ~ 5 ℃ higher than that of the pot heated with cold water.

Insert it directly to create a lower water temperature

Straight or oblique insertion of the pot will also affect the temperature of the extraction water. When the lower pot is heated, the upper pot is directly inserted, and the upper and lower pot is sealed first. The pressure of the lower pot rises sharply, which helps the hot water to rise into the upper pot earlier, so the temperature of the extraction water will be slightly lower. However, if the temperature continues to be heated by a medium fire, the temperature of the upper kettle will soon reach 95 ℃, and the direct insertion method will create a lower temperature, so the firepower control has to be careful.

Oblique insertion to create higher water temperature

If you use the upper pot to insert the pot obliquely to expose the gap for the hot gas to be discharged, keep heating until the spring beads bubble, that is, when the water temperature is a little higher, then straighten the upper pot and seal the upper and lower pot, at this time, the temperature of the extraction water pouring into the upper pot will be 2 ℃ ~ 5 ℃ higher than that of the direct insertion method, depending on the firepower.

Thermometer with firepower is the king.

Whether using direct or oblique insertion, cold water or hot water, when it comes to efficiency and accuracy, it is far less effective and effective than inserting a thermometer with firepower control. With the thermometer-assisted firepower control, we can sum up a set of wind warming curve and get twice the result with half the effort. Only with the assistance of scientific data can we enjoy the wonderful effect of getting twice the result with half the effort.
