Description

Technical Field

[0001] The utility model relates to the technical field of food cooking utensils, in particular to a vacuum low-temperature slow cooking device. Background Art

[0002] Sous vide is a cooking technique that involves cooking food at a low temperature for a long period of time.

[0003] Constant low temperature can reduce the damage to the protein and other nutrients in the food. Vacuum sealing allows water to transfer heat to the food, but at the same time prevents water from directly contacting the food. It not only eliminates the risk of re-contamination and odor caused by oxidation, but also prevents the evaporation of food flavor and water during cooking. During operation, put the food into a sealed bag that can withstand high temperatures, and after exhausting the air in the sealed bag to make it vacuum, put the sealed bag containing the food into constant temperature hot water for soaking, so that the food is gradually "cooked" in the hot water, which can minimize the loss of water.

[0004] The existing vacuum slow cookers on the market often do not have a vacuum function, and require an additional vacuum machine to vacuum-seal the food, which takes up more space and costs, and the machine is also larger in size. Utility Model Content

[0031] The air extraction port 10 is provided with a silicone joint 8. The silicone joint 8 is aligned with the air extraction hole of the sealing bag, and a vacuum negative pressure is applied to the sealing bag through a vacuum pump 11, so that the gas in the sealing bag is extracted to form a vacuum state, and the vacuum pump 11 will discharge the sucked gas from the air outlet 9.

[0032] A start button 15 is provided on the side wall of the housing 2, and the start button 15 is electrically connected to the vacuum pump 11. The start button 15 controls the working state of the vacuum pump 11 to extract the gas in the sealed bag, which is easy to operate.
