[0035] The present invention will be further described below in conjunction with the accompanying drawings:

[0036] like Figure 1 — Figure 5 As shown, this embodiment provides a vacuum dehydration tank for sandwich soft candy slurry, including a dehydration tank body 1, a vacuum system 2, a feeding system 3, a discharge pipe 4, a rotary dehydration system 5 and a water spray purification system 6. The vacuum system 2 is connected to the interior of the dehydration tank body 1 to maintain the negative pressure in the dehydration tank body 1. The rotary dehydration system 5 includes a rotary dehydration beam 53, a rotary dehydration rack 51 and a rotary dehydration tray 52. ​​The rotary dehydration rack 51 is rotatably installed on the rotary dehydration beam 53, and the rotary dehydration beam 53 is rotatably installed in the dehydration tank body 1. The rotary dehydration tray 52 is installed on the rotary dehydration rack 51, and the rotation axis of the rotary dehydration tray 52 is inclined. The feeding system 3 has an outlet. The material inlet and the discharge port of the feeding system 3 point to the side of the rotary dehydration tray 52. ​​The distance between the discharge port of the feeding system 3 and the rotation axis of the rotary dehydration tray 52 is less than the radius of the rotary dehydration tray 52. ​​Each rotary dehydration tray 52 is used to expand the dehydration area and improve the dehydration efficiency. The vacuum system 2 is connected to the top of the dehydration tank body 1, and the discharge pipe 4 is connected to the bottom of the dehydration tank body 1. The water spray purification system 6 is installed on the rotary dehydration beam 53. The water spray purification system 6 has a tank side wall cleaning device 61 and a dehydration tray cleaning device 62. The tank side wall cleaning device 61 points to the inner wall of the dehydration tank body 1, and the dehydration tray cleaning device 62 points to the rotary dehydration tray 52 to improve the cleaning efficiency.

[0037] During feeding, liquid material flows out through the discharge port and drains into the rotary dehydration tray 52. ​​The rotary dehydration tray 52 rotates under the weight of the material, and the material is spread on the rotary dehydration tray 52 for dehydration. The material also drives the rotary dehydration tray 52 to rotate, making the material spread evenly. Since the dehydration surface area is greatly increased, the material is quickly dehydrated. After the material is dehydrated, the tank side wall cleaning device 61 sprays water, driving the rotary dehydration beam 53 to rotate, so that the tank side wall cleaning device 61 evenly cleans the interior of the dehydration tank 1. The dehydration tray cleaning device 62 sprays clean water onto the rotary dehydration tray 52, causing the rotary dehydration tray 52 to rotate, so that each position of the rotary dehydration tray 52 circulates close to the rotary dehydration tray 52, allowing the rotary dehydration tray 52 to be quickly cleaned. The tank side wall cleaning device 61 and the dehydration tray cleaning device 62 are both connected to a cleaning water inlet pipe through a rotary joint. In order to fix the rotary dehydration beam 53 during dehydration, an electromagnet adapted to the rotary dehydration beam 53 is provided in the dehydration tank 1, thereby preventing the rotary dehydration beam 53 from rotating during dehydration. During cleaning, the electromagnet is powered off to facilitate the rotation of the rotary dehydration beam 53.

[0038] Specifically, the dehydration tank body 1 has a lowest point at a position far away from the rotation axis of the rotary dehydration frame 51, and the discharge pipe 4 is located at the lowest point of the dehydration tank body 1 to facilitate material discharge.

[0039] Specifically, the vacuum system 2 includes a vacuum pump, which is connected to the top of the inner side of the dehydration tank 1 to generate negative pressure.

[0040] Specifically, the feeding system 3 includes a feeding pipe 31, a pressure reducing valve 32 and a downstream pipe 33. The feeding pipe 31 is installed on the side wall of the dehydration tank body 1, and the pressure reducing valve 32 is installed on the feeding pipe 31. The downstream pipe 33 bends downward and points to the side of the rotary dehydration disk 52, so that the rotary dehydration disk 52 rotates, which facilitates the spreading of the material and improves the dehydration efficiency.

[0041] Specifically, the rotary dehydration frame 51 includes an upper ejector pin 512, a lower ejector pin 513 and a rotary dehydration rod 514. The upper ejector pin 512 and the lower ejector pin 513 are relatively installed on the rotary dehydration beam 53. The upper ejector pin 512 and the lower ejector pin 513 support and clamp the two ends of the rotary dehydration rod 514, so that the rotary dehydration rod 514 is rotatably installed between the upper ejector pin 512 and the lower ejector pin 513, which facilitates the rotation of the rotary dehydration rod 514 and makes the rotary dehydration tray 52 rotate to spread the material. When the upper ejector pin 512 and the lower ejector pin 513 respectively rotate with the rotary dehydration rod 514, the rotation is smooth because the material is syrupy.

[0042] Specifically, the rotary dehydration tray 52 is provided with a plurality of radially arranged water baffles 521, and adjacent water baffles 521 are provided with drain holes 522 near the rotary axis. The drain holes 522 are used to continue to drain the material to the next rotary dehydration tray 52, so that the multi-layer rotary dehydration trays 52 can spread the material at the same time and speed up the dehydration efficiency. Specifically, a collector 7 is provided between adjacent rotary dehydration trays 52, and the collector 7 is rotatably installed on the rotary dehydration rod 514. The collector 7 includes a material pocket trough 71 and a collecting pipe 72. The material pocket trough 71 is rotatable. It is sleeved and installed on the rotary dewatering rod 514, and a collection channel 711 is provided on the material pocket trough 71. A scraper plate that slides with the rotary dewatering rod 514 is provided on the side of the collection channel 711 to facilitate the collection of materials on the rotary dewatering rod 514 to the collection channel 711. The materials discharged from the discharge hole 522 are collected in the collection channel 711 for redistribution. The collecting pipe 72 is connected to the collection channel 711, and a center of gravity block 712 is provided on the material pocket trough 71. The center of gravity block 712 ensures the stability of the direction of the collecting pipe 72, so that the collecting pipe 72 points to the corresponding rotary dewatering disk 52.

[0043] Specifically, the tank side wall cleaning device 61 includes a side wall water spray column, which is installed on the rotating dehydration beam 53. The side wall water spray column is provided with a number of side wall water spray outlets with the same direction. The direction of each side wall water spray outlet is not in the same plane as the rotation axis of the rotating dehydration beam 53. Each side wall water spray outlet points to the inner wall of the dehydration tank body 1. After the side wall water spray outlet sprays water, it drives the rotating dehydration beam 53 to rotate, thereby cleaning the side wall of the dehydration tank body 1.

[0044] Specifically, the dehydration tray cleaning device 62 includes a plurality of dehydration tray cleaning pipes 621 installed on the rotary dehydration rack 51 , each of which points to the rotary dehydration tray 52 , thereby driving the rotary dehydration tray 52 to rotate and clean the rotary dehydration tray 52 .

[0045] The dehydration process of the vacuum dehydration tank, using a sandwich soft candy slurry vacuum dehydration tank, includes the following steps:

[0046] S1: Turn on the pump to pump the material into the dehydration tank 1, and the vacuum system 2 vacuums the dehydration tank 1;

[0047] S2: The rotary dehydration tray 52 rotates the paving material to increase the dehydration area and improve the dehydration efficiency;

[0048] S3: After dehydration, water is passed through the tank side wall cleaning device 61 and the dehydration tray cleaning device 62. The tank side wall cleaning device 61 sprays water to drive the rotary dehydration beam 53 to rotate, and the dehydration tray cleaning device 62 sprays water to drive each rotary dehydration tray 52 to rotate, cleaning the rotary dehydration tray 52 and the inner wall of the dehydration tank body 1;

[0049] S4: After the solid matter concentration increases from 67% by mass to 69% by mass, the material is discharged from the discharge pipe 4.

[0050] Please note that since this application employs several layers of rotating dehydrating trays 52 for rapid dehydration of the material, under the premise of controlling the flow rate of the feed system 3, the dehydration process is complete when the material flows to the bottom of the dehydration tank 1, thus enabling dynamic feeding and discharging of the material without having to wait until the dehydration tank 1 is full before vacuum dehydration. This lays the foundation for a continuous and uniform supply of material for the continuous molding of the next layer of jelly candies.
