Description

Technical Field

[0001] The invention relates to the field of digesters, in particular to a steam heat flow circulation digester. Background Art

[0002] A steamer is a device that uses a certain heat source to generate heat to heat and cook the food inside. The steamer has the characteristics of large heating area, high thermal efficiency, uniform heating, short liquid boiling time, and easy control of heating temperature.

[0003] Traditional steamers heat food in two ways: 1. The steamer contains water, and the heat generated by the electric heating plate is absorbed by the water, and then passes through the water to the food in the basin, which is commonly known as "water stewing"; 2. The steamer contains water, and the heat generated by the electric heating plate is absorbed by the water to produce a large amount of hot water vapor, which heats the food on the top shelf inside the steamer.

[0004] The above method has the following problems: the temperature is uncontrollable. The heat energy transfer of stewing in water depends entirely on water. The temperature of the water after boiling is constant at around 100°C, and the temperature cannot be controlled; the heat energy transfer is slow. The heat energy of the traditional steamer is first transferred to the water, and then directly or indirectly transferred to the food container through the water, which takes a long time.

[0005] The purpose of this invention is to design a steam heat flow circulation digester to solve the above problems in the prior art. Summary of the Invention

[0006] In view of the problems existing in the above-mentioned prior art, the present invention provides a steam heat flow circulation cooker, which can effectively solve the problems existing in the above-mentioned prior art.

[0007] The technical solution of the present invention is:

[0008] A steam heat flow circulation digester comprises a shell and a base, wherein a heating plate is provided on the bottom surface of the base, and further comprises:

[0009] A holding cavity, consisting of the shell and a corresponding cover, wherein a cup body is placed in the holding cavity;

[0010] A water tank is provided inside the base, the water tank is filled with water, and the water is used to receive the heat emitted by the heating plate and generate water vapor;

[0011] a communicating cavity, for connecting the containing cavity and the base, wherein the containing cavity, the base, and the communicating cavity are connected to form a closed steam circulation chamber; and

[0012] a steam circulation pipe, comprising a steam input pipe and a steam return pipe passing through the communication cavity, wherein the top ends of the steam input pipe and the steam return pipe are respectively arranged above the cup body, one on the left and one on the right, and the bottom ends of the steam input pipe and the steam return pipe are connected to the base; and

[0013] a graphene heat recovery sheet, disposed above the steam input pipe and the steam return pipe, for absorbing the steam heat transferred from the steam input pipe and radiating far infrared rays downward to heat the food in the cup;

[0014] A control system and a temperature sensor, wherein the control system is used to obtain temperature information from the temperature sensor and control the start or stop of the heating plate.

[0015] Furthermore, the top end of the steam return pipe is bent and extended downward, and the upper opening of the steam return pipe is lower than the upper opening of the steam input pipe.

[0016] Furthermore, the heating plate is a graphene heating plate.

[0017] Furthermore, the base is provided with a water inlet, and the water inlet is connected to the water tank.

[0018] Furthermore, the water inlet is provided with a sealing cover.

[0019] Furthermore, the temperature sensor is arranged at the lower end of the cup body to obtain the temperature of the cup body.

[0020] Furthermore, the lower opening of the steam reflux pipe is lower than the lower opening of the steam input pipe.

[0021] Furthermore, the bottom end of the steam input pipe is connected to the upper side of the water tank.

[0022] Furthermore, the bottom end of the steam reflux pipe is connected to the bottom end of the water tank.

[0023] Therefore, the present invention provides the following effects and / or advantages:

[0024] This invention changes the traditional steamer's method of heating food through water-based heat transfer. The base, connecting chamber, steam circulation pipe, and graphene regenerative plate are strategically positioned and sealed to generate internal steam pressure. A graphene regenerative plate is installed on the side of the steam inlet pipe. The heat of vaporization (540 calories per gram) generated by the graphene regenerative plate in contact with the water in the water tank heats the plate. The plate absorbs this heat and converts it into far-infrared radiation with a wavelength of 8-12 microns. This far-infrared radiation propagates downward and toward the interior of the cup, effectively directing the far-infrared radiation directly to the food within the cup, providing penetrating heating. This not only rapidly heats the food but also prevents the partial breakdown of the protein structure in the food caused by the heat transfer, preserving maximum nutrients and effectively maintaining the food's appearance.

[0025] By connecting and sealing the container, connecting chamber, and water tank to form a steam circulation chamber, heat loss is effectively prevented, improving heat utilization. This also generates a certain amount of steam pressure on the food inside the cup, which increases its moisture content during heating. This is particularly useful for bird's nests, preserving their original shape while increasing their moisture content. The steam pressure also allows the nest to absorb water and expand in volume, making it more palatable. This principle also applies to other high-protein foods.

[0026] The present invention arranges the top ends of the steam input pipe and the steam return pipe on the left and right sides respectively above the cup body, and the top end of the steam return pipe bends and extends downward, and the upper opening of the steam return pipe is lower than the upper opening of the steam input pipe. This can effectively ensure that the steam is in full contact with the graphene heat recovery plate on the steam circulation path, so that the graphene heat recovery plate can fully absorb heat energy and release far infrared rays.

[0027] The lower opening of the steam return pipe of the present invention is lower than the lower opening of the steam input pipe, the bottom end of the steam input pipe is connected to the upper side of the water tank, and the bottom end of the steam return pipe is connected to the bottom end of the water tank, so that steam can be transmitted only from the steam input pipe and return to the water tank from the steam return pipe, preventing steam backflow.

[0028] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS
