Description

  The present invention relates to a high-temperature liquid high-speed evaporator, and more particularly to a high-temperature steaming apparatus.

  In conventional techniques, food is usually simmered by placing water in the container, placing the food in water, heating the water in the container with a heating element (electric heating tube, electromagnetic induction coil or burner), and the amount of heat by the water. Is transferred to the food to complete the cooking process. The main methods are as follows.

  FIG. 1 shows a conventional heating wire heating stew. As shown in FIG. 1, the conventional heating wire cooker puts food 14 in a container 11, heats water in the container with an electric heating tube 12 (or an electric hot tray 13), and heats the food 14 with water. To complete the cooking of food.

  FIG. 2 shows a conventional electromagnetic induction heating stew. As shown in FIG. 2, the conventional electromagnetic induction heating stewer puts food 23 in a container 21, heats the wall of the container 21 with an electromagnetic induction coil 22, and converts the heat of the wall of the container 21 into the water in the container 21. And the amount of heat is transmitted to the food 23 with water to complete the cooking process of the food.

  FIG. 3 shows a conventional fuel gas heating stew. As shown in FIG. 3, the conventional fuel gas heating stewer puts the food 33 in the container 31, heats the wall of the container 31 with the burner 32, and transfers the heat amount of the wall of the container 31 to the water in the container 31. Then, the amount of heat is transmitted to the food 33 with water to complete the food boiling operation.

  The above stewers can stew food, but generally have the disadvantage that the stew temperature is low and the high temperature heat source during stew is far from the food, some commercial stewers, stew high desired temperature, or special The following disadvantages exist for stewed food in the environment (eg, high altitude locations).

  1. All of the heating methods used in conventional stewers increase the water temperature by transferring the amount of heat from a high-temperature heat source (eg, the outer surface of an electric heating tube, the outer wall of a container for electromagnetic heating or fuel gas heating) to water. It is to transfer heat to food. From a microscopic angle, the heating process first heats the water on the surface of the high-temperature heat source, and when this part of the water is heated, the density decreases, rapidly floats away from the high-temperature heat source, and accordingly the density is relative. High water sinks, reaches a high temperature heat source, is heated and then floats away rapidly, circulates in this way, and achieves the purpose of heating the water in the container by heat conduction of water If the container is not completely sealed, the water temperature in the container can only reach the saturation temperature corresponding to the atmospheric pressure of the local environment, and the saturation temperature value that can be reached also decreases as the altitude increases. If it is too high, the water temperature will be too low, and the cooking time will be too long. In serious cases, it will be difficult to cook food.

  2. For commercial stewers, the size of the container is set according to the maximum amount of food sold within a unit time, but the actual sales amount always changes, and a small amount of food is boiled. In general, food can be boiled only by heating the whole water in the container to the boil temperature, and the heat supply amount cannot be set rationally according to the boiled amount, resulting in waste of energy. There is.

  In order to eliminate the disadvantages existing in the prior art, the present invention provides a continuous heating by partitioning a small amount of water from the container by a shield case and restricting this portion of water to the vicinity of the high-temperature heat source of the heat conductor. The problem is that vaporization and overheating are completed quickly, and the food is heated directly with the generated high-temperature steam, thus increasing the boiling temperature of the food, and in high altitude areas, it is difficult to boil the food unless a pressure vessel is used. It is an object to provide a high-temperature steaming apparatus that not only solves the problem, but also rationally sets the supply of heat according to the amount of food boiled to achieve the purpose of saving energy and reducing consumption.

Discharged and heats food in the material basket 172.

  FIG. 34 is a schematic view of the heating structure of the electric heating tube of Example 4 of the high-temperature steaming apparatus according to the present invention. As shown in FIG. 34, the electric heating element 185 is provided in the heat conductor 184 to constitute the electric heating tube. Then, the electric heating tube is attached to the side wall of the container 181. The shield case 183 has a tubular shape, encloses the heat conductor 184 therein, a water inlet is provided at the bottom of the shield case 183, a high-temperature fluid discharge port is provided at the top, and the electric heating element 185 heats the heat conductor 184 In this case, after the water between the shield case 183 and the heat conductor 184 is heated, the generated high-temperature fluid is discharged from the high-temperature fluid discharge port on the upper surface of the shield case 183, and the food in the material basket 182 is heated.

  The high-temperature steaming apparatus according to the present invention partitions a small amount of water from a container by a shield case, restricts the water in this portion to the vicinity of the high-temperature surface of the heat conductor, and places it in the high-temperature heating region of the heat conductor for a long time. If the water is continuously heated and the water in the container is located near the boiling point of the water, supply a small amount of energy to the heat conductor, and only a small amount of water separated from the shield case is heated centrally to vaporize and overheat. The generated high-temperature steam can be applied to the food in the material basket to increase the cooking temperature of the food, reduce heat transfer loss, and save a large amount of energy. In particular, the simple structure of the present invention can solve the difficult problem that the cooking temperature is low and the food is difficult to cook at the atmospheric pressure in the highland area.

  For those skilled in the art, the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. The present invention has been described in detail with reference to the above-described embodiment. Should still be understood that the technical solutions described in the preceding embodiments can be modified or some technical features thereof can be equally replaced. Any changes, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
