[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, an improved adsorption dryer includes a heater 100, a first adsorption tower 200, a second adsorption tower 300, a cooler 1, a gas recovery module 400 and a steam-water separator 500. The heater 100 is connected to the output ends of the first adsorption tower 200 and the second adsorption tower 300, the cooler 1 is connected in series to the pipeline between the gas recovery module 400 and the steam-water separator 500, and the steam-water separator 500 is connected to the output ends of the first adsorption tower 200 and the second adsorption tower 300 respectively. During the implementation process, compressed air enters from the air inlet pipe, a portion of the compressed air enters the gas recovery module 400 through the regulating valve, and a portion of the compressed air (about 15% of the total gas, referred to as regenerated gas) enters the heater 100 and is heated to 120-180°C. The high-temperature regenerated gas then enters the second adsorption tower 300 through the sixth shut-off valve to heat, dry and dehydrate the adsorbent in the second adsorption tower 300. The regenerated gas then enters the gas recovery module 400 through the fourth shut-off valve, merges with the intake air, enters the cooler 1 for cooling, condenses water from the mixed gas, and then enters the gas-water separator 500 to separate gas and water (water is discharged from the gas-water separator 500). The compressed air then enters the first adsorption tower 200 through the seventh shut-off valve for drying and dehydration, and then enters the outlet pipe through the first shut-off valve for use at the back end.

[0023] The second stage, as attached Figure 3As shown, the second adsorption tower 300 adsorbs the first adsorption tower 200 for regeneration, and compressed air enters from the air inlet pipe 9. A portion of the compressed air enters the gas recovery module 400 through the regulating valve 3, and a portion of the compressed air (about 15% of the total gas, referred to as regenerated gas) enters the heater 100 and is heated to 120-180°C. Then the high-temperature regenerated gas enters the first adsorption tower 200 through the fifth stop valve, and the adsorbent in the first adsorption tower 200 is heated, dried and dehydrated. Then the gas is regenerated and enters the gas recovery module 400 through the third stop valve, merges with the intake air, enters the cooler 1 for cooling, and condenses water from the mixed gas. Then, the gas enters the gas-water separator 500 to separate gas and water (water is discharged from the gas-water separator 500). Then, the compressed air enters the second adsorption tower 300 through the eighth stop valve for drying and dehydration, and then enters the gas outlet pipe 10 through the second stop valve for use at the rear end.

[0024] Furthermore, a pre-cooling plate 5 arranged in a linear array is slidably provided in the cooler 1, a cavity 8 is provided in the pre-cooling plate 5, and a copper sheet 11 is symmetrically provided on the end surface of the pre-cooling plate 5, and a linear array of protrusions 12 is provided on the copper sheet 11;

[0025] It also includes a communication component, which at least includes a communication pipe 9 fixedly installed in the cavity 8 and connected to another adjacent cavity 8.

[0026] Specifically, by arranging a pre-cooling plate 5 in the cooler 1, the product that needs to be freeze-dried can be directly placed in the pre-cooling plate 5 for pre-cooling, avoiding contamination when placed outside for natural cooling. After the product is placed in the pre-cooling plate 5, cooling liquid is poured into the cavity 8 opened in the pre-cooling plate 5, so that the cooling liquid can cool the product placed in the pre-cooling plate 5, so that the product can be pre-cooled in the freeze dryer, and the multiple cavities 8 are kept connected by the installed connecting pipe 9, so that the cooling effect of the cooling liquid is faster, and the low temperature of the cooling liquid is quickly transferred to the product through the copper sheet 11 installed on the end surface of the pre-cooling plate 5, so that the pre-cooling effect of the product is faster, and when pre-cooling the emulsion product, the array of bumps 12 on the copper sheet 11 can transfer the temperature to the product more quickly, so that the emulsion product is cooled faster.

[0027] In the above embodiment, when the temperature of the product is too high and needs to be pre-cooled, the product is directly poured into the pre-cooling tray 5 so that the pre-cooling tray 5 can pre-cool the product. By injecting cooling liquid into the cavity 8, the cooling liquid cools the pre-cooling tray 5, so that the pre-cooling tray 5 can maintain a low temperature state to pre-cool the product. The multiple cavities 8 are connected by the connecting pipe 9, so that the multiple pre-cooling trays 5 can maintain uniform efficiency. The installed copper sheet 11 cooperates with the protrusion 12, so that the temperature of the cooling liquid can be quickly transferred to the emulsion product, thereby making the pre-cooling effect of the emulsion product faster, not only improving the pre-cooling efficiency of the product, but also avoiding product contamination, reducing the workers' operating steps, and improving the freeze-drying efficiency.

[0028] As an embodiment further provided by the present invention, a linear array of slide grooves 4 is provided in the cooler 1 , and a pre-cooling plate 5 is movably connected in the slide grooves 4 .

[0029] Specifically, by providing a plurality of chutes 4 in the cooler 1 , the pre-cooling tray 5 can be quickly installed into the cooler 1 through the chutes 4 , thereby making it convenient to install and remove the pre-cooling tray 5 .

[0030] As another embodiment further provided by the present invention, sealing blocks 6 are symmetrically provided on the side walls of the pre-cooling plate 5 , and the sealing blocks 6 are communicated with the cavity 8 .

[0031] Furthermore, the side wall of the cooler 1 is provided with a linear array of conduits 7 , one end of which is inserted into the sealing block 6 .

[0032] Specifically, the sealing block 6 installed on the pre-cooling plate 5 is connected to the cavity 8, so that when the conduit 7 installed on the cooler 1 is inserted into the interior of the sealing block 6, the conduit 7 can be connected to the cavity 8, so that the conduit 7 can inject the coolant into the cavity 8, and the conduit 7 is fixed and sealed by the sealing block 6, thereby avoiding leakage at the connection between the conduit 7 and the pre-cooling plate 5.

[0033] As another embodiment further provided by the present invention, a liquid storage tank 2 is fixedly mounted on the side wall of the cooler 1 , a liquid supply pipe 3 is symmetrically provided on the top of the liquid storage tank 2 , and a conduit 7 is fixedly connected to the side wall of the liquid supply pipe 3 .

[0034] Furthermore, a liquid supply pump 13 is fixedly installed in the liquid storage tank 2 .

[0035] Specifically, the coolant stored in the liquid storage tank 2 is pumped into the liquid supply pipe 3 through the liquid supply pump 13, so that the liquid supply pipe 3 can quickly transfer the coolant to the conduit 7, so that the conduit 7 can inject the coolant into the cavity 8 opened in the pre-cooling plate 5. When cooling is completed, the coolant can be withdrawn by providing suction through the liquid supply pump 13.

[0036] Working principle: When the temperature of the product is too high and needs to be pre-cooled, the high-temperature product is directly poured into the pre-cooling tray 5, and the coolant in the liquid storage tank 2 is pumped into the liquid supply pipe 3 by driving the liquid supply pump 13, so that the liquid supply pipe 3 transmits the coolant to the conduit 7, and the coolant is injected into the cavity 8 opened in the pre-cooling tray 5 through the conduit 7, so that the coolant can pre-cool the product in the pre-cooling tray 5, and the conduit 7 is sealed by the sealing block 6 to prevent the coolant from overflowing the cavity 8 during the infusion process. When the coolant infusion is completed, the multiple cavities 8 are connected through the connecting pipe 9 installed on the pre-cooling tray 5, so that the coolant in the multiple cavities 8 maintains the same heat dissipation efficiency. By installing a copper sheet 11 on the pre-cooling tray 5, the copper sheet 11 can transfer the cooling temperature to the emulsion product more quickly, and the array of bumps 12 on the copper sheet 11 can provide the efficiency of temperature transfer of the copper sheet 11, thereby making the heat dissipation effect of the emulsion product faster, which not only improves the pre-cooling effect of the product, but also allows the product to be freeze-dried quickly.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
