[0085] See also Figures 5 to 8 As shown, in some embodiments, the cooking device may include a vacuum frying system. This system can be used to vacuum-fry food at low temperatures. Compared to conventional frying, the oil temperature during vacuum frying is typically controlled between 80°C and 100°C, significantly lower than the 160°C to 230°C of conventional frying. This low-temperature treatment effectively reduces the damage to heat-sensitive nutrients in food, such as vitamins and antioxidants, thereby better preserving the food's nutritional value.

[0086] It should be noted that in a vacuum environment, the boiling point of water in food is lowered, allowing it to evaporate quickly, significantly shortening the drying time. This not only improves production efficiency but also reduces the adverse changes that may occur in food due to prolonged high-temperature treatment, and ensures a crispy and delicious taste.

[0087] Because vacuum frying allows the moisture in food to escape directly as steam rather than absorbing large amounts of oil, the oil content of vacuum-fried foods can be significantly lower than that of traditional fried foods, typically between 10% and 20%, contributing to a healthier diet.

[0088] Low-temperature processing and rapid dehydration help preserve the original color and flavor of food. The aroma and flavor components in food are less likely to be lost in the vacuum state. Instead, they are concentrated due to the reduced water content, making the product crispier and more flavorful.

[0089] During the vacuum frying process, due to the extremely low moisture content and the fact that it is carried out in an oxygen-free environment, it can effectively inhibit the growth of microorganisms, extend the shelf life of food, and facilitate storage and transportation.

[0090] This technology is applicable to a variety of food raw materials, including but not limited to fruits, vegetables, dried fruits, aquatic products, and livestock and poultry meat, and can produce snack foods with unique taste and rich nutrition.

[0091] See also Figures 2 to 8 As shown, in some embodiments, the vacuum frying system can be provided inside the drawer 21. It should be noted that, in other embodiments, the vacuum frying system can also be provided inside the box 1, and the vacuum frying system can be provided in other areas outside the inner container 11.

[0092] See also Figures 5 to 8As shown, in some embodiments, the vacuum frying system may include a frying tub 3. A frying chamber 30 may be formed inside the frying tub 3. The frying chamber 30 may be used to hold oil, which may be heated to fry the food in the frying chamber 30.

[0093] In some embodiments, the vacuum frying system may include a vacuum module 4. The vacuum module 4 may be in communication with the frying chamber 30 within the frying tub 3. The vacuum module 4 is configured to evacuate the frying chamber 30. Thus, the food may be vacuum-fried at low temperatures within the frying chamber 30.

[0094] In some embodiments, a vacuum connection 313 may be provided on the outer wall of the frying tub 3, communicating with the frying chamber 30. The vacuum module 4 may be in communication with the vacuum connection 313. The vacuum module 4 may extract air from the frying chamber 30 through the vacuum connection 313, thereby achieving a vacuum in the frying chamber 30.

[0096] See also Figures 9 to 11 As shown, in some embodiments, the frying tub 3 may include a tub body 31. A frying cavity 30 may be formed inside the tub body 31. An opening communicating with the frying cavity 30 may be provided at the top of the tub body 31.

[0097] In some embodiments, the vacuum connector 313 may be protruding from the outer wall of the barrel body 31. The vacuum connector 313 may be disposed at a top area of the outer wall of the barrel body 31. The vacuum connector 313 may be disposed near the top opening of the barrel body 31.

[0098] See also Figures 9 to 11 As shown, in some embodiments, the frying tub 3 may include a tub cover 32. The tub cover 32 may be movably disposed on the top surface of the tub body 31. The tub cover 32 may be used to cover the top opening of the tub body 31, and further used to open and close the frying chamber 30.

[0099] In some embodiments, the barrel cover 32 can be rotatably covered on the top surface of the barrel body 31. The barrel cover 32 can rotate relative to the barrel body 31 to open or close the frying chamber 30.

[0100] It should be noted that, in other embodiments, the barrel cover 32 may also be detachably provided on the top opening of the barrel body 31 .

[0101] In some embodiments, when the drawer 21 is pulled out of the drawer box 2 , the barrel cover 32 can be exposed outside the drawer box 2 , so that the barrel cover 32 can be rotated to open or close the top opening of the barrel body 31 , thereby facilitating the opening and closing of the frying chamber 30 .

[0102] See also Figures 9 to 11 As shown, in some embodiments, the frying tub 3 may include a mesh cylinder 33. The mesh cylinder 33 may be disposed within the frying chamber 30. The mesh cylinder 33 may be used to hold food to be fried. The oil within the frying chamber 30 may flow into the mesh cylinder 33, thereby frying the food within the mesh cylinder 33.
