Description

Low pressure vacuum steamer

The present invention relates to a low-pressure vacuum steamer, and more particularly, a low-pressure vacuum capable of improving the cooking efficiency of noodles and steamed dishes while evenly distributing steam (pressure, temperature) in the inner space of each multi-layered container. It's about the steamer.

The pressure vessel for cooking can be used as a normal vessel while the inside of the cooking chamber expands during boiling to discharge steam through a device that functions as a pressure valve. In addition, when it is cooled down after boiling, the inside of the cooking chamber shrinks to block the inflow of outside air through a device that functions as a pressure valve, and it performs a pumping function that continuously pulls the lid down while evacuating the inside to open the lid. It sticks to the container and does not fall off. If the contents are stored in such a vacuum state, the inconvenience of continuously boiling and storing the food can be eliminated by preventing the food from spoiling while the vacuum is maintained.

In other words, the function of the container that enables vacuum in the container currently manufactured by casting, die-casting, or bending with stainless steel is to expand by steam generated inside the container body when boiling by heating, and this expansion pressure is It is used as a cooking container while discharging steam to the outside through a pressure valve formed on the lid.

When cooled for storage for a while after boiling in this way, the internal pressure of the main body expanded inside the container body is gradually contracted, while the pressure valve mounted on the container lid blocks the inflow of external air into the container. As the lid is continuously pulled down, the packing mounted on the lid of the container is more closely attached to the rim of the support of the container body, thereby depressurizing the inside of the body, so that arbitrary separation is impossible while the container lid is covered with the container body. Therefore, if the food cooked as it is in such a reduced pressure state is stored, air from the outside does not flow into the food in the main body, thereby preventing the cooked food from spoiling.

Then, in order to release this decompression state inside the body, the lid is easily opened when the pressure valve is operated to allow external air to pass through the inside of the body. On the other hand, in general, cooking containers are cooked by heating an airtight container containing food (rice, noodles, steam, etc.) with a heating means of electricity or gas. , thereby performing high-quality cooking.

However, despite the fact that conventionally used cooking containers have different shapes of containers according to the types of dishes to be cooked and provide differentiated steam, they cannot always provide steam in a variety of ways according to the types of dishes because of the constant size of containers, Due to this, there was a point that high-quality cooking and various cooking were impossible, and when the lid of the container is removed from the container body and the cooked contents are taken out, the container lid contains steam at high temperature and it is inconvenient to find a suitable place to put it. There were several problems such as

The inner cylinder 212 is upwardly coupled to the first and second central holes 120h and 130h, respectively, and the outer cylinder 214 is downwardly coupled to the second and third central holes 130h and 160h, respectively, to the inner cylinder 212 and the outer cylinder. (214) is slidably fitted to each other and can be stretched. That is, even if the height (difference in depth) of the container part is different, the length is easily adjusted to correspond to the height (depth) of the container part. On the other hand, the first and second steam distribution units 110 and 120 form the steam hole B in an elliptical shape extending in the longitudinal direction at regular intervals so that even if the length of the outer cylinder 214 and the inner cylinder 212 varies, the steam hole ( B) overlaps each other and is not blocked.

As such, the present invention provides the second to third container parts 120 and 130, which are stacked in multiple stages on the first container part 110, ... of the first container part 120 located at the bottom of the nth container part. It is possible to solve the conventional problem that steam (steam) cannot be sequentially provided through the container portion of each layer. In addition, as the steam (temperature, pressure) inside the container is evenly distributed in the container part of each layer, it is suitable for cooking not only noodles and steamed dishes, but also various ingredients such as steamed bread, dumplings, sweet potatoes, corn, and frozen foods, and the cooking quality is improved. . In addition, since steam (pressure) uniformly distributed in the container can be automatically discharged, the airtightness can be maintained at low pressure even after cooking is completed, so that efficient low-pressure steamed cooking is possible and optimal steamed cooking can be provided.
