At present, the common bird's nest products on the market are in various forms: freshly soaked bird's nest, freshly stewed bird's nest, ready-to-cook bird's nest, and bird's nest drinks. Among them, bird's nest gel food is relatively rare, and bird's nest gel food in aerogel state with a high specific surface area is even rarer.

During the general implementation, a supercritical fluid (such as carbon dioxide supercritical fluid) is filled into the upper part of the drying kettle to a set air pressure, and the kettle body is maintained at a set temperature. The bird's nest gel is dried using the supercritical fluid to obtain a bird's nest gel food with a high specific surface area. However, in the prior art, the movement state of the supercritical fluid in the drying kettle is stable, which will lead to low drying efficiency and deviation in drying effect. In addition, in the prior art, the drying kettle also has the problem of incomplete discharge of the supercritical fluid containing waste liquid.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] As attached Figure 1 and 2 As shown, this embodiment provides a technical solution: a supercritical drying kettle for bird's nest gel, comprising a kettle body 1, a discharge port 4 is provided at the bottom of the kettle body 1, a valve is provided on the discharge port 4, an inlet port 5 is provided on one side of the top of the kettle body 1, and a sealing cover plate 6 is provided on the top of the kettle body 1 (in the specific example, the sealing degree is ensured by a gasket, and the fastening connection is achieved by bolts), a bird's nest placement frame is installed in the kettle body 1, and a circulating pump 13 and a nitrogen tank 17 are adjacent to the outside of the kettle body 1, the air inlet end of the circulating pump 13 is connected to the lower part of the inner cavity of the kettle body 1 through a first pipeline 15, and the air outlet of the circulating pump 13 is connected to the upper part of the inner cavity of the kettle body 1 through a second pipeline 16, and the wall of the first pipeline 15 is connected to the output port of the nitrogen tank 17 through a branching third pipeline 18, and valves are provided on the first pipeline 15 and the third pipeline 18.

[0024] In the drying step, the supercritical gas enters the kettle body 1 and maintains a certain gas pressure, and the kettle body 1 is kept at a certain temperature. At this time, the circulation pump 13 is started to pump the fluid from bottom to top to achieve the circulation of the supercritical fluid. In this process, the first pipeline 15 is opened and the third pipeline 18 is closed;

[0025] In the step of discharging the supercritical fluid, the discharge port 4 is opened. Under the action of the air pressure difference, the waste liquid is quickly discharged along with the supercritical fluid. As the air pressure difference decreases, the discharge speed slows down. At this time, the third pipeline 18 is opened, the first pipeline 15 is closed, the circulation pump 13 is started, and nitrogen is filled into the upper part of the kettle body 1 to promote the discharge of the supercritical fluid.

[0026] In a specific design, an electric heater 20 is provided inside the kettle body 1 , and a first thermometer 19 is installed on the sealing cover plate 6 , and the temperature inside the kettle body 1 is maintained by the cooperation of the two.

[0027] See attached Figure 1As an exemplary structural design, the bird's nest placement frame includes a vertical rod 10, the top of the vertical rod 10 is provided with an X-shaped frame 9, the distal end of the X-shaped frame 9 is a plug-in portion, the upper inner wall of the kettle body 1 is provided with a vertical slide 8 for installing the plug-in portion, the vertical slide 8 has four groups, and the rod body of the vertical rod 10 is provided with a plurality of bird's nest grid frames 11 from top to bottom; preferably, there are five groups of bird's nest grid frames 11, and the height difference between adjacent bird's nest grid frames 11 is not less than 10cm. In addition, in order to facilitate the extraction of the bird's nest placement frame, a handle 12 can also be provided on the X-shaped frame 9, which is connected to the frame arm opposite to the front and rear.

[0028] See attached Figure 1 As an exemplary structural design, it also includes a support plate 2 and support plate legs 3 for supporting the kettle body 1. The bottom of the kettle body 1 passes through the bottom surface of the support plate 2. This structural design is mainly used to support the kettle body 1.

[0029] In a specific design, a pressure gauge 7 is installed on the sealing cover plate 6 , and the external supercritical fluid is pumped into the kettle body 1 , and the air pressure in the kettle body 1 can be observed through the pressure gauge 7 . Example

[0030] See attached Figure 1 and 4 This embodiment is improved on the basis of the first embodiment as follows: it further comprises a tube heater 14 , and the second pipeline 16 is connected to the kettle body 1 through the tube heater 14 .

[0031] In the exemplary structural design, the tube heater 14 includes a cylinder 141, in which a heat-conducting liquid, which may be an aqueous solution, is filled, and a heating rod 142 is installed in the cylinder 141. The cylinder 141 includes a spiral tube 145, and the lower port of the spiral tube 145 passes through the bottom wall of the cylinder 141 and is connected to the upper port of the second pipe 16, and the upper port of the spiral tube 145 passes through the top wall of the cylinder 141 and is connected to the kettle body 1.

[0032] Preferably, the spiral tube 145 is a copper tube, which has extremely high thermal conductivity and is conducive to rapid heating.

[0033] In a specific design, the tube heater 14 further includes a second thermometer 144 and a temperature controller 143 , and the temperature controller 143 can be adjusted to control the working power of the heating rod 142 .

[0034] In implementation 1, since the second pipe 16 is outside the kettle body 1, it is easy to cause the supercritical temperature to drop, thereby affecting the drying effect. In order to avoid temperature loss during fluid circulation, implementation 2 is designed to solve the above problem by adding a pipe heater 14.

[0035] In some other embodiments, the design may be as follows: on the basis of the first embodiment, the electric heater 20 inside the kettle body is removed, and a tube heater 14 is added (this drying kettle structure is not shown in the figure), and the temperature inside the entire kettle body 1 is maintained by the tube heater 14 (of course, this requires the kettle body 1 to have a higher thermal insulation function).

[0036] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
