[0022] The present invention will be further described below with reference to the drawings: As Figure 1 — Figure 5As shown in the figure, this embodiment provides a vacuum dehydration tank for soft sandwich syrup, which includes a dehydration tank body 1, a vacuum pumping system 2, a feeding system 3, a discharge pipe 4, a rotary dehydration system 5 and a water spraying and purification system 6. The vacuum pumping system 2 is connected to the inside of the dehydration tank body 1 to maintain a negative pressure inside the dehydration tank body 1. The rotary dehydration system 5 includes a rotary dehydration beam 53, a rotary dehydration frame 51 and a rotary dehydration disk 52. The rotary dehydration frame 51 is rotatably installed on the rotary dehydration beam 53, the rotary dehydration beam 53 is rotatably installed inside the dehydration tank body 1, the rotary dehydration disk 52 is installed on the rotary dehydration frame 51, and the rotation axis of the rotary dehydration disk 52 is inclined. The feeding system 3 has a discharge port, and the discharge port of the feeding system 3 points to the side of the rotary dehydration disk 52. The distance between the discharge port of the feeding system 3 and the rotation axis of the rotary dehydration disk 52 is less than the radius of the rotary dehydration disk 52. The discharge port of the feeding system 3 points to the rotary dehydration disk 52. Each rotary dehydration disk 52 is used to increase the dehydration area and improve the dehydration efficiency. The vacuum pumping system 2 is connected to the top of the dehydration tank body 1, the discharge pipe 4 is connected to the bottom of the dehydration tank body 1, and the water spraying and purification system 6 is installed on the rotary dehydration beam 53. The water spraying and purification system 6 has a tank side wall cleaning device 61 and a dehydration disk cleaning device 62. The tank side wall cleaning device 61 points to the inner side wall of the dehydration tank body 1, and the dehydration disk cleaning device 62 points to the rotary dehydration disk 52 to improve the cleaning efficiency.

[0023] During feeding, the liquid material flows out through the discharge port, and the material spills into the rotary dehydration disk 52. Under the gravity of the material, the rotary dehydration disk 52 spreads on the rotary dehydration disk 52 for dehydration. At the same time, the material drives the rotary dehydration disk 52 to rotate, making the spreading uniform. Due to the greatly increased dehydration surface area, rapid dehydration of the material is achieved. After the material dehydration is completed, 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 inside of the dehydration tank body 1. The dehydration disk cleaning device 62 sprays clean water onto the rotary dehydration disk 52, causing the rotary dehydration disk 52 to rotate, so that each position of the rotary dehydration disk 52 circulates close to the rotary dehydration disk 52, enabling the rotary dehydration disk 52 to be quickly cleaned. Both the tank side wall cleaning device 61 and the dehydration disk cleaning device 62 are externally 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 inside the dehydration tank body 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.

[0024] Specifically, the dehydration tank body 1 has a lowest point at a position far from the rotation axis of the rotary dehydration frame 51, and the discharge pipe 4 is located at the lowest point position, facilitating the discharge of the material.

[0025] Specifically, the vacuum pumping system 2 includes a vacuum pump, and the vacuum pump is connected to the top inside the dehydration tank body 1 to generate a negative pressure.

[0026] Specifically, the feeding system 3 includes a feed pipe 31, a pressure reducing valve 32 and a downstream pipe 33. The feed pipe 31 is installed on the side wall of the dehydration tank body 1, the pressure reducing valve 32 is installed on the feed pipe 31, and 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, facilitating the spreading of materials and thus improving the dehydration efficiency.

[0027] Specifically, the rotary dehydration rack 51 includes an upper thimble 512, a lower thimble 513 and a rotary dehydration rod 514. The upper thimble 512 and the lower thimble 513 are oppositely installed on the rotary dehydration beam 53.

When the upper thimble 512 and the lower thimble 513 respectively rotate in adaptation with the rotary dehydration rod 514, due to the syrup nature of the materials, the rotation is smooth.

[0028] Specifically, a number of radially arranged water separation plates 521 are provided on the rotary dehydration disk 52. A drain hole 522 is provided at a position close to the rotation axis between adjacent water separation plates 521. The drain hole 522 is used to continue draining the materials to the next layer of rotary dehydration disk 52, facilitating the simultaneous spreading of materials by multiple layers of rotary dehydration disks 52 and accelerating the dehydration efficiency. Specifically, a collector 7 is provided between adjacent rotary dehydration disks 52. The collector 7 is rotatably sleeved on the rotary dehydration rod 514. The collector 7 includes a material collecting trough 71 and a collecting pipe 72. The material collecting trough 71 is rotatably sleeved on the rotary dehydration rod 514. An aggregate channel 711 is formed on the material collecting trough 71. A scraping plate slidably matched with the rotary dehydration rod 514 is provided on the side of the aggregate channel 711, facilitating the concentration of the materials on the rotary dehydration rod 514 into the aggregate channel 711. The materials drained from the drain hole 522 are collected in the aggregate channel 711 for redistribution. The collecting pipe 72 is communicated with the aggregate channel 711. A gravity block 712 is provided on the material collecting trough 71. The gravity block 712 ensures the stability of the pointing direction of the collecting pipe 72, so that the collecting pipe 72 points to the corresponding rotary dehydration disk 52.

[0029] Specifically, the side wall cleaning device 61 of the tank body includes side wall water spray columns. The side wall water spray columns are installed on the rotary dehydration beam 53. A number of side wall water spray nozzles with a unified pointing direction are provided on the side wall water spray columns. The pointing directions of the side wall water spray nozzles are not in the same plane as the rotation axis of the rotary dehydration beam 53. Each side wall water spray nozzle points to the inner side wall of the dehydration tank body 1. After the side wall water spray nozzles spray water, the rotary dehydration beam 53 is driven to rotate, thereby cleaning the side wall of the dehydration tank body 1.

[0030] Specifically, the dehydrating disk cleaning device 62 includes a number of dehydrating disk cleaning pipes 621 installed on the rotary dehydrating rack 51. Each dehydrating disk cleaning pipe 621 points to the rotary dehydrating disk 52, thereby driving the rotary dehydrating disk 52 to rotate, and realizing the cleaning of the rotary dehydrating disk 52.

[0031] The dehydration process of the vacuum dehydration tank uses a sandwich soft syrup vacuum dehydration tank, and includes the following steps: S1: Start the feeding pump to pump the material into the dehydration tank body 1, and the vacuum pumping system 2 evacuates the dehydration tank body 1. S2: The rotary dehydrating disk 52 rotates to spread the material, increasing the dehydration area and improving the dehydration efficiency. S3: After dehydration, both the tank body side wall cleaning device 61 and the dehydrating disk cleaning device 62 are filled with water. The tank body side wall cleaning device 61 sprays water to drive the rotary dehydrating beam 53 to rotate, and the dehydrating disk cleaning device 62 sprays water to drive each rotary dehydrating disk 52 to rotate, cleaning the rotary dehydrating disk 52 and the inner side wall of the dehydration tank body 1. S4: After the solid concentration rises from 67% by mass concentration to 69% by mass concentration, it is discharged from the discharge pipe 4.

[0032] Please note that since the present application is provided with a number of layers of rotary dehydrating disks 52 for rapid dehydration of the material, on the premise of controlling the flow rate of the feeding system 3, when the material flows to the bottom of the dehydration tank body 1, the dehydration process has been completed, and dynamic feeding and discharging can be realized, without waiting until the dehydration tank body 1 is filled before performing vacuum dehydration. This lays the foundation for the continuous and uniform supply of materials for the continuous molding of the next-stage sandwich soft candy.
