Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to a slow-cooking container. Background Technology
[0002] Braised beef in a clay pot, one of the "Three Wonders of Qishilin," remains a signature dish that is a must-order at every table after a century. It is served in a covered earthenware pot. Currently, the earthenware pots used are traditional, and their heat retention is not ideal. As the dining time increases, the temperature inside the pot gradually decreases, weakening the original aroma and flavor of the dish. This causes the beef to become tough and dry, and the broth to gradually solidify, preventing the dish from reaching its optimal texture. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a slow cooking container.
[0004] The technical solution adopted in this utility model is:
[0005] A type of stewing container, the main body of which is a stewing pot with a large belly and a narrow mouth. The stewing pot has a double-layer structure. The outer layer has a round hole at the lower edge of the large belly. The bottom of the outer layer of the stewing pot is hollow or hollowed out. The outer periphery of the bottom has an open skirt-shaped edge. The interior is used to set floating wax to ensure that the food is kept at a constant temperature during the meal.
[0006] The aforementioned slow-cooking container features a double-layer insulation design, with the inner layer providing insulation while the outer layer remains cool, thus preventing burns from high temperatures and maintaining the final product temperature. The entire container is manufactured using a single-piece molding and high-temperature firing process, combining technology, aesthetics, and practicality.
[0007] Preferably, in the above-mentioned stewing container, the round holes are evenly distributed at the lower edge of the outer belly of the stewing pot, with a quantity of 5-10.
[0008] Preferably, the above-mentioned stewing container has symmetrical handles on both sides of the stewing pot, making it convenient for service personnel and customers to pick up.
[0009] Preferably, in the above-mentioned stewing container, the height of the open skirt-shaped edge is not less than 32mm.
[0010] Preferably, in the above-mentioned slow cooking container, the bottom of the inner layer of the slow cooking pot is provided with a honeycomb-shaped heat-conducting texture.
[0011] Preferably, the above-mentioned stewing container also includes a soup warming base, which is placed below the open, skirt-shaped edge. The stewing pot and the soup warming base are used together, and the floating wax is lit during the meal. This not only makes the overall shape more beautiful and complete, but also maintains the temperature of the product throughout the meal. The floating wax is not only safely placed inside the container, providing great safety and aesthetics and ensuring the safety of diners, but it can also maintain a long-lasting burn, increasing its practicality.
[0012] Preferably, in the above-mentioned stewing container, the warm soup base is made of copper.
[0013] The beneficial effects of this utility model are:
[0014] The aforementioned slow-cooking container features a simple yet ingenious design. Its wide belly not only retains heat and aroma but also allows the fragrances of various ingredients to blend and interact within the container. The round perforations provide air circulation, ensuring proper burning of the wax and allowing for real-time monitoring of the flame, while also offering a subtly aesthetically pleasing effect. The textured honeycomb pattern ensures even heating of the bottom of the container during cooking, improving thermal efficiency and allowing the food to absorb more flavor. When used in conjunction with a copper warming base, the slow-cooking container provides continuous heating throughout the meal, ensuring a consistent serving temperature. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] like Figure 1-6As shown, the braising container is a large-bellied, narrow-mouthed braising pot 1. The bottom of the pot is equipped with a warming base 2. The pot has a double-layer structure, designed to keep the inner side warm while preventing the outer side from getting hot, thus avoiding burns and maintaining the serving temperature. The entire pot is integrally molded and fired at high temperature, combining technology, aesthetics, and practicality. The lower edge of the outer layer of the double-layer structure has five round holes 3. The bottom of the outer layer is hollow or perforated, with an open, skirt-shaped edge 4 approximately 33mm high around its perimeter. This edge is used to hold floating wax, ensuring a constant temperature for the food during dining. The bottom of the inner layer of the double-layer structure has a honeycomb-like heat-conducting texture (image omitted) to ensure even heating of the bottom of the pot during the braising process, improving thermal efficiency. Symmetrical handles 5 on both sides of the pot facilitate handling by service personnel and customers. The soup warmer base is made of copper and is placed below the open, skirt-shaped edge. The hot pot is used together with the soup warmer base, and the floating wax is lit during the meal. This not only makes the overall shape more beautiful and complete, but also maintains the temperature of the product throughout the meal. The floating wax is not only safely placed inside the container, providing great safety and aesthetics, ensuring the safety of diners, but it also burns continuously, increasing its practicality.
[0025] When cooking the traditional delicacy, braised beef in a clay pot, the beef is kept at a constant temperature within the pot until fully cooked, resulting in increasingly flavorful meat. The double-layered structure, round holes, and honeycomb-like heat-conducting texture work together to allow the broth to penetrate the ingredients more effectively. Throughout the meal, the food maintains a highly consistent temperature, making the beef incredibly tender and flavorful, and the broth thick and rich, ensuring the optimal taste is maintained.
[0026] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
