Description

Technical Field

[0001] The utility model belongs to the technical field of sugar beet processing and sugar making, and specifically relates to a sugar beet sugar making exudation heat treatment device. Background Art

[0002] Sugar beet is one of the main raw materials for the sugar industry, and its root contains a relatively high sugar content. Sugar beets in China are mainly planted north of 40° north latitude, including three major production areas in the northwest, north China and northeast China. Among them, the northwest production area has the characteristics of long sunshine hours, and the yield per unit area and sugar content of sugar beets are both relatively high. During the production process of sugar beet sugar factories, a large amount of water is required for the flow and washing of sugar beets, the exudation of sugar, the dilution of materials, the cooling of equipment, the generation and condensation of steam, etc. At present, due to the introduction of advanced technologies and equipment, the production water consumption has been greatly reduced, but sugar beet sugar factories are still large water consumers. In the process of sugar exudation (juice extraction) in sugar beet sugar making, an exudation heat treatment device is needed to fully break the cells of sugar beet shreds, and then make them fully contact and mix with high-temperature water or thin sugar juice. Under given conditions, the sucrose in sugar beets is extracted as much as possible, and the non-sugars are left in the waste sugar beet shreds as much as possible to obtain high-purity leaching juice. A large amount of exudation water is consumed in this process, resulting in an increase in production costs. Therefore, it is necessary to design a sugar beet sugar making exudation heat treatment device that can save exudation water consumption. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a sugar beet sugar making exudation heat treatment device that can save exudation water consumption.

[0009] Compared with the prior art, the utility model has the following advantages:

The liquid outlet 2 is communicated with a filter 9 through a first liquid pump 8. The output end of the filter 9 is connected to the water supply pipeline 11 through the circulation pipeline 10. The output end of the water supply pipeline 11 is connected to the input end of a second liquid pump 12. The output end of the second liquid pump 12 is connected to the heat blancher 13. A concentration sensor 14, a tee joint, and a first solenoid valve 15 are sequentially installed on the circulation pipeline 10. The other branch of the tee joint is fixedly connected to a delivery pipeline 18. A second solenoid valve 16 is installed on the delivery pipeline 18. A third solenoid valve 17 is installed at the output end of the water supply pipeline 11. The concentration sensor 14 is in communication connection with the controller. The first solenoid valve 15, the second solenoid valve 16, and the third solenoid valve 17 are all controlled by the controller.

[0015] It should be noted that, in this embodiment, the elevator 7 adopts a chain plate elevator, the filter 9 adopts a mechanical filter commonly used in this industry, and the scalder 13 adopts a liquid circulation heater. The above equipment are all existing devices and will not be described in detail in this article.

[0016] In order to convey the beet shreds into the device of this embodiment, the feeding mechanism includes a shaftless screw conveyor 19 and a feeding hopper 20. The lower end of the feeding hopper 20 is fixedly connected to the input end of the shaftless screw conveyor 19, the lower end of the shaftless screw conveyor 19 is fixedly connected to the upper end of the seepage box 1, the output end of the shaftless screw conveyor 19 is connected to the top of the seepage box 1, and the shaftless screw conveyor 19 is driven by its own motor.

[0017] In order to clean the shredded vegetable residue that has been subjected to the seepage and blanching treatment in the seepage box 1 out of the seepage box, the residue unloading mechanism includes a hydraulic telescopic cylinder 21 and a push plate 22. The hydraulic telescopic cylinder 21 is fixedly connected to the inner wall of the seepage box 1, and the output end of the hydraulic telescopic cylinder 21 is fixedly connected to the push plate 22. The lower end of the push plate 22 is in contact with the upper end of the filter screen plate 4, and the movement direction of the output end of the hydraulic telescopic cylinder 21 is parallel to the upper end surface of the filter screen plate 4.

[0018] In order to allow the liquid containing sugar in the residue storage tank 6 to flow back into the seepage box 1, the lower end of the residue storage tank 6 is connected to the bottom of the seepage box 1 through a through hole, and a filter net 23 is fixedly connected in the through hole. The filter net 23 can block the vegetable residue outside the seepage box 1.

[0019] In order to disperse the beet shreds entering the seepage box 1 to various places on the filter screen plate 4 and prevent the beet shreds from being piled up, a material distribution baffle 24 is fixedly connected to the seepage box 1 below the output end of the feeding mechanism.

[0020] The specific working process of the utility model is as follows:

[0021] Add the shredded beets to the feed hopper 20, start the shaftless screw conveyor 19, and convey the shredded beets to the diffuser box 1. The shredded beets are dispersed and dropped onto the filter screen plate 4 under the action of the distribution baffle 24. The diffusing water heated by the heat exchanger 13 is sprayed onto the shredded beets through the spray disc 3 to dissolve and carry away the sugar in the beets. The diffused liquid enters the liquid outlet 2 through the filter screen plate 4, and after being conveyed by the first liquid pump 8, the crushed residues mixed in the diffused liquid are removed through the filter 9, and then enter the circulation pipeline 10. The concentration sensor 14 on the circulation pipeline 10 real-time detects the sugar content of the diffused liquid in the circulation pipeline 10 and transmits the signal to the controller. When the sugar content is not lower than the set value of the controller, the controller controls the first solenoid valve 15 to close and the second solenoid valve 16 and the third solenoid valve 17 to open. At this time, the diffused liquid is conveyed to the next process for treatment through the conveying pipeline 18. When the sugar content is lower than the set value of the controller, the controller controls the first solenoid valve 15 to open and the second solenoid valve 16 and the third solenoid valve 17 to close. At this time, the diffused liquid flows into the circulation pipeline 10, enters the heat exchanger 13 through the second liquid pump 12 for heating, and then enters the spray disc 3 to spray the shredded beets in the diffuser box 1, replacing the diffusing water in the water supply pipeline 11 to heat and diffuse the shredded beets until the sugar concentration of the diffused liquid is not lower than the set value of the controller. After heating and diffusing for a certain time, the sugar in the shredded beets in the diffuser box 1 is completely diffused and becomes beet pulp residue. At this time, open the discharge box door 5 and start the hydraulic telescopic cylinder 21. The output end of the hydraulic telescopic cylinder 21 extends to drive the baffle 22 to push the beet pulp residue on the filter screen plate 4 towards the discharge box door 5 on the other side, and finally discharge the beet pulp residue out of the diffuser box 1 and fall into the slag storage tank 6, and is conveyed to the pulp residue storage place through the elevator 7.
