Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figure 1-6 , the present utility model provides a technical solution:

[0025] A drying device for producing food-grade carbon dioxide includes a housing 1 for externally protecting internal components; the interior of the housing 1 is fixedly connected with a filter barrel 2, a heating barrel 3, a condensation barrel 4, and an adsorption barrel 5 respectively. An air filter element 6, a heating mechanism 7, a superconduction mechanism of quartz 8, and a water-absorbing filler 9 are respectively arranged inside the filter barrel 2, the heating barrel 3, the condensation barrel 4, and the adsorption barrel 5. The bottom of the filter barrel 2 is communicated with an intake pipe 10, the top of the filter barrel 2 is communicated with the top of the heating barrel 3, the bottom of the heating barrel 3 is communicated with the bottom of the condensation barrel 4, the top of the condensation barrel 4 is communicated with the top of the adsorption barrel 5, the bottom of the adsorption barrel 5 is communicated with a shunt pipe 11, and the bottom of the condensation barrel 4 is communicated with an outlet water pipe 12.

[0026] During use, the food-grade carbon dioxide to be dried is introduced into the filter barrel 2 from the air inlet pipe 10. The air filter element 6 in the filter barrel 2 filters the dust in the food-grade carbon dioxide. The filtered food-grade carbon dioxide enters the heating barrel 3 from the upper part of the filter barrel 2 (the filter barrel 2 is designed with a bottom-in and top-out air circulation, which is convenient for adding a vertical three-way joint at the bottom of the air inlet pipe for side inlet of carbon dioxide and bottom outlet of filtered dust, with a small risk of filter element blockage). Then, the heating mechanism 7 in the heating barrel 3 heats the food-grade carbon dioxide to ensure the vaporization state of the moisture in the food-grade carbon dioxide and dry part of the water vapor. After that, the heated food-grade carbon dioxide enters the condensation barrel 4 from the bottom of the heating barrel 3. The heat of the food-grade carbon dioxide is quickly adsorbed and exported by the superconduction mechanism 8 of the stone in the condensation barrel 4, thereby realizing the rapid condensation of the hot water vapor in the food-grade carbon dioxide to form water droplets, which are exported from the bottom water outlet pipe 12, thus realizing the dehydration and drying of the food-grade carbon dioxide, and the temperature of the discharged carbon dioxide can be close to normal temperature, with little safety hazard. Then, the food-grade carbon dioxide enters the adsorption barrel 5 from the top of the condensation barrel 4. The water-absorbing filler 9 in the adsorption barrel 5 further adsorbs the remaining water vapor, thereby ensuring the drying quality of the device. The dried food-grade carbon dioxide is exported from the shunt pipe 11, completing the efficient and rapid drying of the food-grade carbon dioxide.

[0027] In this embodiment, please refer to Figure 1 , a top cover 13 is fixedly connected to the top of the housing 1 for sealing the tops of the housing, the filter barrel, the heating barrel, the condensation barrel and the adsorption barrel; a feed pipe 14 is communicated on the surface of the top cover 13 and at a position corresponding to the adsorption barrel 5, which is convenient for connecting an external filler automatic feeding system to realize automatic replacement of the water-absorbing filler of the drying device and facilitate intelligent control.

[0028] In this embodiment, please refer to Figure 3 , heat-insulating materials 15 are filled on the outside of the filter barrel 2, the heating barrel 3, the condensation barrel 4 and the adsorption barrel 5 inside the housing 1 for heat insulation inside and outside the housing, which can avoid heat loss, has good energy-saving performance, and can also realize heat insulation between the barrels inside the housing to prevent heat from mixing randomly, ensuring the independent operation of each barrel; the outside of the condensation barrel 4 is closely attached to the inner wall of the housing 1 through a heat-conducting block 16, and heat-dissipating fins 17 are fixedly connected to the outside of the housing 1 at equal intervals for external heat dissipation in cooperation with the superconduction mechanism of the stone, realizing rapid condensation inside the condensation barrel.

[0029] In this embodiment, please refer to Figure 5 , the heating mechanism 7 includes a honeycomb ceramic body 71, which is convenient for the flow of food-grade carbon dioxide and improves the internal heat storage capacity; an electric heater 72 is fixedly connected inside the honeycomb ceramic body 71 for heating the honeycomb ceramic body.

[0030] In this embodiment, please refer to Figure 6, the superconducting guiding mechanism 8 is made by connecting multiple layers of concave porous superconducting quartz arc plates 81 through superconducting quartz struts 82, enabling gas to flow through. The multi-layer design has a good condensation effect. At the same time, the arc design facilitates the middle reflux of condensed water to fall into the lower drain pipe.

[0031] In this embodiment, please refer to Figure 2 , the shunt pipe 11 includes a vertically downward discharge pipe 111 and an air outlet pipe 112 perpendicular to the discharge pipe 111, realizing the side discharge of food-grade carbon dioxide and the bottom discharge of the replaced water-absorbing filler, meeting the design of automatic filler replacement.

[0032] In this embodiment, please refer to Figure 2 , the bottom of the housing 1 is fixedly connected with legs 18 at equal intervals for the overall fixed installation of the device.

[0033] When the single food-grade carbon dioxide production drying device is in use: directly connect the air outlet pipe of the food-grade carbon dioxide to the inlet pipe 10.

[0034] When the multi-food-grade carbon dioxide production drying device is in use: first perform multi-pipeline shunting on the air outlet pipe of the food-grade carbon dioxide, and then connect the outlets of each shunt pipeline separately to the inlet pipe 10 of a food-grade carbon dioxide production drying device.
