Figure 8 is Figure 7 A schematic diagram of the structure from another perspective.

[0087] Please refer to Figures 5 to 8 As shown, in some embodiments, the cooking device may include a vacuum frying system. The vacuum frying system can be used for vacuum low-temperature frying of food ingredients. Compared with conventional frying, the oil temperature during vacuum low-temperature frying is usually controlled between 80°C and 100°C, far lower than 160°C to 230°C in conventional frying. Such low-temperature treatment can effectively reduce the damage to heat-sensitive nutrients in food, such as vitamins and antioxidants, thus better retaining the nutritional value of food.

[0088] It should be noted that in a vacuum environment, the boiling point of water in food decreases and can evaporate rapidly, greatly shortening the drying time. It can not only improve production efficiency, but also reduce the possible adverse changes in food due to long-term high-temperature treatment, and the taste is crispy and delicious.

[0089] Since frying is carried out in a vacuum state, the water in food can be directly converted into steam and escape, rather than absorbing a large amount of oil. Therefore, the oil content of vacuum-fried food can be significantly lower than that of traditional fried food, generally between 10% - 20%, which helps to provide a healthier diet option.

[0090] Low-temperature treatment and rapid dehydration help to maintain the original color and flavor of food. The flavor components in food are not easily lost in a vacuum state, but will be concentrated due to the reduction of water, making the product taste more crispy and flavorful.

[0091] During the vacuum frying process, due to the extremely low water content and being 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.

[0092] 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 meats, and can produce leisure foods with unique tastes and rich nutrition.

[0093] Please refer to Figures 2 to 8 As shown, in some embodiments, the vacuum frying system can be disposed inside the drawer 21. It should be noted that in other embodiments, the vacuum frying system can also be disposed inside the box body 1, and the vacuum frying system can be disposed in other areas outside the inner liner 11.

[0094] Please refer to Figures 5 to 8As shown, in some embodiments, the vacuum frying system may include a frying barrel 3. A frying cavity 30 may be formed inside the frying barrel 3. The frying cavity 30 can be used to place oil, and after the oil is heated, the ingredients in the frying cavity 30 can be fried.

[0095] In some embodiments, the vacuum frying system may include a vacuum pumping module 4. The vacuum pumping module 4 can communicate with the frying cavity 30 inside the frying barrel 3. The vacuum pumping module 4 is used to pump the air out of the frying cavity 30. Therefore, vacuum low-temperature frying of the ingredients can be performed in the frying cavity 30.

[0096] In some embodiments, a vacuum joint 313 communicating with the frying cavity 30 may be provided on the outer wall of the frying barrel 3. The vacuum pumping module 4 can communicate with the vacuum joint 313. The vacuum pumping module 4 can extract the air in the frying cavity 30 through the vacuum joint 313, thereby realizing pumping the air out of the frying cavity 30.

[0097] Figure 9 is Figure 5 a schematic exploded view of. Figure 10 is Figure 9 a schematic structural view of the frying barrel 3 and the driving module 5 in. Figure 11 is Figure 10 a schematic exploded structural view of.

[0098] Please refer to Figures 9 to 11 As shown, in some embodiments, the frying barrel 3 may include a barrel body 31. The frying cavity 30 may be formed inside the barrel body 31. An opening communicating with the frying cavity 30 may be provided at the top of the barrel body 31.

[0099] In some embodiments, the vacuum joint 313 may protrude from the outer wall of the barrel body 31. The vacuum joint 313 may be provided in the top region of the outer wall of the barrel body 31. The vacuum joint 313 may be arranged close to the top opening of the barrel body 31.

[0100] Please refer to Figures 9 to 11 As shown, in some embodiments, the frying barrel 3 may include a barrel cover 32. The barrel cover 32 may be movably covered on the top surface of the barrel body 31. The barrel cover 32 can be used for the top opening of the barrel body 31, and thus for opening and closing the frying cavity 30.

[0101] In some embodiments, the barrel cover 32 may be rotatably covered on the top surface of the barrel body 31. The barrel cover 32 can rotate relative to the barrel body 31, thereby opening or closing the frying cavity 30.

[0102] It should be noted that in other embodiments, the barrel cover 32 may also be detachably covered at the top opening of the barrel body 31.
