[0002] With the development of science and technology and the progress of the times, L-arabinose, also known as arabinose and pectinose, is a pentose with a chemical formula of C5H 10 O5. In nature, L-arabinose rarely exists in the form of monosaccharides. It usually combines with other monosaccharides and exists in the form of heteropolysaccharides in gum, hemicellulose, pectin acid, bacterial polysaccharides and certain glycosides. It is highly stable to heat and acid, and needs to be produced and fermented by fermentation equipment.

[0003] The existing L-arabinose production and fermentation device needs to provide an aerobic environment during use. Therefore, after the oxygen supply operation is completed, air may easily enter the oxygen supply pipe due to airflow exchange problems, affecting the purity of the oxygen supply mechanism's next oxygen supply. Utility Model Content

[0007] A fermentation barrel body, wherein a movable plate is connected to the upper inner side of the fermentation barrel body, and a strain delivery box is plugged into the upper inner side of one side of the inner wall of the fermentation barrel body, an oxygen supply cylinder is installed on the upper outer side of one side of the fermentation barrel body, and a baffle is arranged at one end of the oxygen supply cylinder, a movable disk is connected to the inner side of the oxygen supply cylinder, and a movable sheet is movably connected to the front of the movable disk, a first reserved hole is provided on the front of the movable sheet, a second reserved hole is provided on the front of the movable disk, the top and bottom of the movable disk are slidably connected to tracks, and the tracks are connected to the inner wall of the oxygen supply cylinder, and a heating column is plugged into the inner bottom of the fermentation barrel body.

[0008] Preferably, a feed port is connected to the top of the fermentation barrel body, and a discharge port is installed below one side of the outer wall of the fermentation barrel body, an air outlet is fixed above one side of the outer wall of the fermentation barrel body, and a valve is installed on the inner side of the air outlet.

[0009] Preferably, the baffle is connected to the strain delivery box via a connecting shaft.

[0010] Preferably, the top of the baffle is movably connected to the bottom plate, and the bottom plate is slidably connected to the strain delivery box.

[0011] Preferably, one side of the track is in an inclined structure.

[0012] Preferably, the bottom plate forms a movable structure through a shaft and a baffle.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the utility model, by setting the oxygen supply cylinder, the movable disk, the movable sheet and the baffle, after the oxygen supply mechanism is started, oxygen is transported to the oxygen supply cylinder through the oxygen supply pipe. After the setting work of the aerobic environment for L-arabinose is completed, the movable sheet is reset under the action of the elastic member, and the first reserved hole and the second reserved hole are staggered, and the air inside the isolation device enters the oxygen supply pipe, and only remains in the oxygen supply cylinder, which will not affect the oxygen supply pipe and the oxygen supply mechanism.

[0021] Reference Figure 1-3 , a production and fermentation device of L-arabinose, comprising a fermentation barrel body 1, a movable plate 3 is connected to the upper inner side of the fermentation barrel body 1, and a strain delivery box 6 is inserted above one side of the inner wall of the fermentation barrel body 1, the movable plate 3 is connected to the inner wall of the fermentation barrel body 1 by an elastic member, the elastic member can reset the movable plate 3, and when there is an external force pushing the surface of the movable plate 3, an opening can be formed between the relatively distributed movable plates 3, an oxygen supply cylinder 8 is installed above one side of the outer wall of the fermentation barrel body 1, and a baffle 7 is arranged at one end of the oxygen supply cylinder 8, a movable disk 11 is connected to one side of the inner side of the oxygen supply cylinder 8, and a movable sheet 14 is movably connected to the front of the movable disk 11, a first reserved hole 15 is opened on the front of the movable sheet 14, and a second reserved hole 15 is opened on the front of the movable disk 11 The reserved hole 16, the top and bottom of the movable disk 11 are slidably connected with the track 12, and the track 12 is connected to the inner wall of the oxygen delivery cylinder 8, one side of the track 12 is an inclined structure, the movable disk 11 can move along the track 12, and one side of the track 12 is inclined, which can abut the movable sheet 14, so that the movable sheet 14 moves downward relative to the movable disk 11, then the first reserved hole 15 and the second reserved hole 16 intersect, forming an opening, which is convenient for oxygen output, and the inner bottom of the fermentation barrel body 1 is plugged with a heating column 9, and the electric heating wire inside the heating column 9 is started, so that it boils the liquid after the reaction inside the fermentation barrel body 1, so the ethanol produced after the reaction can volatilize, so that the concentration of L-arabinose produced by fermentation is purer;

[0022] The top of the fermentation barrel body 1 is connected with a feed inlet 2, and a discharge port 10 is installed at the lower side of the outer wall of the fermentation barrel body 1. An air outlet 4 is fixed on the upper side of the outer wall of the fermentation barrel body 1, and a valve 5 is installed on the inner side of the air outlet 4. When the valve 5 is opened, the ethanol to be volatilized can be discharged along the inner side of the air outlet 4. The baffle 7 is connected to the strain delivery box 6 through the connecting shaft 13. The baffle 7 is an L-shaped structure, which can block one end of the oxygen supply cylinder 8 and can block the bottom of the strain delivery box 6. The top of the baffle 7 is movably connected with a bottom plate 17, and the bottom plate 17 and the strain delivery box 6 are slidably connected. The bottom plate 17 and the baffle 7 form a movable structure through the shaft body. After the upper part of the baffle 7 rotates with the connecting shaft 13, it can drive the bottom plate 17 close to the end of the connecting shaft 13 to move up. Therefore, a V-shaped structure is formed between the bottom plate 17 and the upper surface of the baffle 7, which is convenient for the strains on the bottom plate 17 to slide down to the inside of the fermentation barrel body 1.

[0023] Working principle: When in use, the staff first feeds the grading liquid through the feed port 2, and the gravity of the grading liquid presses down the movable plate 3 and enters the interior of the fermentation barrel 1. Then, the oxygen supply mechanism is started, so that the oxygen enters the oxygen delivery cylinder 8 along the oxygen supply pipe. The baffle 7 is opened under the push of oxygen, so that the bottom plate 17 is driven by the upper part of the baffle 7, and the end of the bottom plate 17 near the connecting shaft 13 moves up, forming a V-shaped structure with the upper surface of the baffle 7. Then, the bacteria placed on the surface of the bottom plate 17 moves out of the bacteria delivery box 6. At the same time, the device is in an aerobic environment, which is convenient for the device to ferment L-arabinose through the bacteria, and the heating is started. The electric heating wire inside the column 9 boils the liquid after the reaction inside the fermentation barrel 1, so the ethanol produced after the reaction can volatilize, making the concentration of the fermented L-arabinose purer, and the valve 5 is opened, so that the ethanol to be volatilized can be discharged along the inner side of the air outlet 4. Finally, after completing the setting of the aerobic environment for L-arabinose, the movable sheet 14 is reset under the action of the elastic member, and the first reserved hole 15 and the second reserved hole 16 are staggered, isolating the air inside the device from entering the oxygen supply pipe, and only remaining in the oxygen delivery cylinder 8, which will not affect the oxygen supply pipe and the oxygen supply mechanism, so that the oxygen purity of the oxygen supply pipe and the oxygen supply mechanism remains unchanged when supplying oxygen next time.
