[0002] In the production of starch sugar, saccharification of starch raw materials is one of the pre-processing steps. When saccharifying the raw materials, the starch raw materials (such as whole wheat flour, corn flakes, cassava), enzyme solution and water need to be transported to the saccharification tank, and the sugar in the raw materials is extracted by heating and stirring to form a saccharification liquid.

[0003] However, during the saccharification reaction of raw materials, insufficient stirring in the saccharification tank is common, which not only increases the saccharification reaction time of the raw materials and reduces production efficiency, but also causes incomplete extraction of raw sugar, thereby causing waste of raw materials and increasing production costs.

Figure 2 It is a sectional view of a production tank for starch sugar of the present utility model. Figure 3 It is a schematic structural view of the stirring mechanism and the filter plate of a production tank for starch sugar of the present utility model. Figure 4 It is an exploded view of the stirring mechanism of a production tank for starch sugar of the present utility model, as Figures 1-4As shown in the figure, a production tank for starch sugar in a preferred embodiment is shown, including: a saccharification tank 1 and a stirring mechanism 2. The top of the saccharification tank 1 is provided with a feed hopper 11, and the bottom is provided with a discharge pipe 14. The stirring mechanism 2 is used to stir the raw materials for the saccharification reaction in the saccharification tank 1. The stirring mechanism 2 includes a rotating bracket 23, a number of rotating shafts 25, a number of connecting rods 26, a fixed gear 22 and a driving member. The rotating bracket 23 is rotatably arranged in the saccharification tank 1. A number of rotating shafts 25 are longitudinally distributed and are circumferentially rotatably installed on the rotating bracket 23. One end of each of the number of connecting rods 26 is connected to the bottom of the number of rotating shafts 25 respectively, and the other end is connected with a stirring shaft 27. The stirring shaft 27 is perpendicular to the connecting rod 26 and parallel to the rotating shaft 25. A number of stirring blades 28 are circumferentially distributed on the side wall of each stirring shaft 27. The fixed gear 22 is arranged above the rotating bracket 23 and is installed on the inner wall of the top of the saccharification tank 1. A transmission component 24 is provided between the fixed gear 22 and each rotating shaft 25. The driving member is in transmission connection with the rotating bracket 23 and is used to drive the rotating bracket 23 to rotate. When the rotating bracket 23 rotates, the fixed gear 22 drives the rotating shaft 25 to rotate through the transmission component 24.

[0037] During production and processing, raw materials, enzyme solution and water are transported into the saccharification tank 1 through the feed hopper 11. The raw materials in the saccharification tank 1 are heated and stirred by the stirring mechanism 2. When the stirring mechanism 2 stirs, the driving member drives the rotating bracket 23 to rotate, and synchronously drives a number of stirring shafts 27 to move circumferentially along the rotating bracket 23, and makes a number of stirring blades 28 on each stirring shaft 27 move circumferentially along the rotating bracket 23 and stir the raw materials. At the same time, the fixed gear 22 drives the rotating shaft 25 to rotate through the transmission component 24. The rotation drives the stirring shaft 27 to move circumferentially along the rotating shaft 25 through the connecting rod 26, and drives the stirring blades 28 on the stirring shaft 27 to move circumferentially along the rotating shaft 25 and stir the raw materials. The sugar in the raw materials is extracted under the action of the enzyme solution and water to produce a saccharified liquid.

[0038] In this embodiment, when the stirring mechanism 2 stirs, a number of stirring shafts 27 not only move circumferentially along the rotating bracket 23, and stir the raw materials through a number of stirring blades 28 on each stirring shaft 27, but also a number of rotating shafts 25 will rotate self - sufficiently, and make a number of stirring shafts 27 move circumferentially along a number of rotating shafts 25 respectively, and make a number of stirring blades 28 on each stirring shaft 27 stir the raw materials again. This not only greatly improves the stirring degree of raw materials, enzyme solution and water, improves the saccharification reaction efficiency, but also improves the extraction degree of sugar in the raw materials, reduces the waste degree of raw materials, and thus reduces the cost.

[0039] Further, as a preferred embodiment, the transmission assembly 24 includes a transmission shaft 241, a driven gear 242, and a transmission member 243. The transmission shaft 241 is rotatably mounted on the rotating bracket 23. The driven gear 242 is drivingly connected to the transmission shaft 241 and meshes with the fixed gear 22. The transmission member 243 is disposed between the transmission shaft 241 and the rotating shaft 25. When the transmission shaft 241 rotates, the transmission shaft 241 drives the rotating shaft 25 to rotate through the transmission member 243. When the rotating bracket 23 rotates, it drives the driven gear 242 to move circumferentially along the fixed gear 22. Since the driven gear 242 meshes with the fixed gear 22, the driven gear 242 rotates self-driven at this time and drives the transmission shaft 241 to rotate synchronously. The transmission shaft 241 drives the rotating shaft 25 to rotate through the transmission member 243.

[0040] Further, as a preferred embodiment, the transmission member 243 is a structure of a spur gear set.

[0041] Further, as a preferred embodiment, the transmission ratio of the transmission member 243 is equal to one.

[0042] Further, as a preferred embodiment, the driving member is a driving motor 21. The driving motor 21 is installed on the top of the saccharification tank 1, and the output end of the driving motor 21 extends into the saccharification tank 1 and is connected to the top of the rotating bracket 23.

[0043] Further, as a preferred embodiment, a filter screen 3 is further provided in the saccharification tank 1. The filter screen 3 is disposed below the stirring mechanism 2, and the filter screen 3 has a plurality of filter holes 31 for filtering the waste residue in the saccharification liquid and improving the quality of the saccharification liquid.

[0044] Further, as a preferred embodiment, the top end face of the filter screen 3 is an inclined surface. The filtered waste residue can be accumulated at the lowest point of the top end face of the filter screen 3 under the guidance of the inclined surface. On the one hand, it avoids the blockage of the filter screen 3 by the waste residue, and on the other hand, it is convenient for the removal of the waste residue after the extraction and discharge of the sugar in the raw material.

[0045] More preferably, an electric heating plate can be installed on the inner wall of the saccharification tank 1 to heat the internal raw materials to accelerate the saccharification reaction between the raw materials, enzyme solution, and water.

[0046] Further, as a preferred embodiment, in order to facilitate the removal of the waste residue accumulated on the filter screen 3, the side wall of the saccharification tank 1 has a slag discharge port 17. The slag discharge port 17 is located at the lowest point of the top end face of the filter screen 3, and a slag discharge door 16 is pivotally connected at the slag discharge port 17.

[0047] Further, as a preferred embodiment, the incoming hopper is communicated with the top of the saccharification tank 1 through the feed pipe 12, and a first solenoid valve 13 is provided on the feed pipe 12 to control the opening or closing of the feed pipe 12. A second solenoid valve 15 is provided on the discharge pipe 14 to control the opening or closing of the discharge pipe 14.

[0048] Further, as a preferred embodiment, a liquid level gauge (not shown in the figure) is further provided on the inner wall of the top of the saccharification tank 1 for detecting the liquid level in the saccharification tank 1.
