Description

Technical Field

[0001] The invention relates to the technical field of L-valine fermentation, in particular to a high-density fermentation production device for L-valine and a process thereof. Background Art

[0002] L-valine is a natural essential amino acid for the human body. It is an essential amino acid. The requirement of adult males is 10 mg / (kg·d). The physiological effect of L-type is twice that of D-type. Lack of L-valine can cause neurological disorders, stagnation of development, weight loss, anemia, etc. As a nutritional supplement, it can be used together with other essential amino acids to prepare amino acid infusions and comprehensive amino acid preparations. It can be used as a nutritional supplement as the main component of amino acid infusions and comprehensive amino acid preparations.

[0028] The present invention provides a high-density fermentation production device for L-valine and a process thereof. Compared with the prior art, it has the following beneficial effects:

[0029] (1) The L-valine high-density fermentation production equipment and process thereof, when the fermentation of L-valine is completed, the driving motor drives the cleaning soft brush to rotate through the transmission shaft and the stirring blades, so as to rotate the mixture of L-valine and fermentation liquid, and the fermentation liquid is thrown out through the through hole by centrifugal force to purify the L-valine while cleaning the inside of the through hole, thereby avoiding clogging of the through hole and affecting the separation efficiency of the equipment.

[0030] (2) The L-valine high-density fermentation production equipment and process thereof, after the fermentation liquid is separated, enters the storage bin through the discharge pipe, and the fermentation liquid drips onto the purification filter plate by gravity, so that the used fermentation liquid can be stored and purified and filtered at the same time, avoiding the used fermentation liquid from flowing into the outside and contaminating the ring, thereby improving the practicality of the device.

[0031] (3) The L-valine high-density fermentation production equipment and process thereof, when the L-valine liquid is separated, it enters the storage bin through the discharge pipe for storage. When the L-valine on the sliding plate is heavy enough, the sliding plate is driven downward until the rotating block enters the slot. The servo motor drives the stirring plate to rotate to stir and break up the L-valine. This can evenly store the L-valine in the storage bin and prevent the L-valine from accumulating and condensing for a long time, which makes it impossible for the extraction pipe to discharge the L-valine.

[0063] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0064] When working, the first solenoid valve 43 and the second solenoid valve 45 are opened, and the staff inputs the fermentation raw materials into the blocking bin 40 through the feed pipe 44, and then inputs the fermentation liquid into the fermentation bin 2 through the liquid inlet pipe 42 to ferment the fermentation raw materials.

The driving motor 50 drives the fermented liquid and the L-valine mixture to rotate through the transmission shaft 51 and the stirring blade 52. The fermented liquid in the mixture is separated by centrifugal force and discharged through the through hole 41 to complete the purification of L-valine, so as to avoid the fermented liquid being mixed with L-valine for storage and affecting the storage time of L-valine. At the same time, the stirring blade 52 drives the first solenoid valve 43 to rotate to clean the inside of the through hole 41 to avoid clogging of the inside of the through hole 41. The fermented liquid falls into the purification filter plate 61 by gravity to purify and filter the fermented liquid, so as to avoid the used fermented liquid from polluting the annular ring.

[0066] When the fermentation liquid inside the L-valine is completely thrown out, the third solenoid valve 47 is opened, and the L-valine enters the storage bin 60 through the discharge pipe 46 for storage, and the drying ring 62 is started to dry the L-valine, so that the L-valine is always kept dry and the storage time is extended. When the L-valine falls on the top of the sliding plate 63, the sliding plate 63 is driven to be pressed down, and the sliding plate 63 drives the return spring 65 to be pressed down until the rotating block 67 enters the slot 68, and the servo motor 66 is started. The servo motor 66 rotates the rotating block 67, the slot 68, the sliding plate 63 and the stirring plate 64 to rotate the L-valine, so that the L-valine can be evenly stored in the storage bin 60.
