Description

Technical Field

[0001] The invention relates to the technical field of fermentation, in particular to a calcium propionate fermentation device. Background Art

[0002] Calcium propionate is a safe and reliable food and feed mildew inhibitor approved for use by the World Health Organization and the Food and Agriculture Organization of the United Nations. Like other fats, calcium propionate can be absorbed by humans and animals through metabolism and provide them with the necessary calcium. This advantage is unmatched by other mildew inhibitors.

[0003] Calcium propionate is produced by the fermentation reaction of propionic acid and a suspension of calcium hydroxide or calcium carbonate. Propionic acid is injected into the suspension of calcium hydroxide or calcium carbonate, and the raw materials in the fermentation tank should reduce contact with the outside world to avoid contamination of the tank. Therefore, when adding raw materials to the tank, it is necessary to be very careful to avoid incomplete fermentation of the raw materials or waste of raw materials. In addition, the injected raw materials are also easily adsorbed on the inner wall of the fermentation tank, affecting the reaction of propionic acid. At the same time, the existing propionic acid is injected once, and the injected propionic acid is too concentrated, which will cause the reaction to slow down. In addition, the fermentation tank as a whole needs to be cleaned after multiple uses, but it does not have a corresponding cleaning structure inside, so that the overall cleaning effect is not high during cleaning, and the inner wall of the tank is not easy to clean, affecting subsequent fermentation.

[0047] Working principle: A suspension of calcium hydroxide or calcium carbonate is injected into the fermentation tank body 10 through the injection hole 19, and then the rotating drum 20 on the first bearing is rotated stably by the rotating motor 17, the first pulley 26, the second pulley 24 and the transmission belt 25. The rotating stirring blades 21 on the lower periphery of the rotating drum 20 mix and stir the inside of the fermentation tank body 10. During the mixing and stirring process, propionic acid raw materials are injected into the feed rack 30. The rotating cam 23 on the top of the rotating drum 20 abuts against the arc block 42 during the rotation process and enters the arc groove 46. In the process, the piston rod 41 on the arc block 42 is pushed by the rotating cam 23, and the piston rod 41 drives the piston plate 44 to move, so that the raw materials in the conveying cylinder 40 are injected into the fermentation tank body 10 in a timely and quantitative manner, and the rotating cam 23 falls off the arc groove 46 in the arc block 42, and the piston plate 44 is reset by the telescopic spring 45.

[0048] When the fermentation and stirring are finished, the screw 22 under the rotating handle 27 on the top of the rotating cylinder 20 is operated to rotate. During the rotation of the screw 22, the lifting block 65 is driven to convert the rotational motion into linear motion in the fixed cylinder 60. During the lifting process, the lifting block 65 drives the half gear 64 on the rotating rod 63 to perform symmetrical rotational motion through the rotating plate 67 and the connecting plate 66. The half gear 64 meshes and drives the rack plate 62 on the limiting base 61 to push back and forth toward the two ends of the supporting cylinder 51. When the rack plate 62 pushes, it pushes the movable block 53 in the supporting cylinder 51, so that the movable rod 52 on the movable block 53 fits the arc cleaning rod 50 with the inner wall of the fermentation tank body 10, and the rotating arc cleaning rod 50 is used to scrape and clean the inner wall of the fermentation tank body 10. When the half gear 64 drives the movable block 53 to retract, the movable rod 52 drives the arc cleaning rod 50 to fall off the inner wall of the fermentation tank body 10, and at the same time, the rubber cleaning brush at the top of the supporting cylinder 51 scrapes and cleans the outer periphery of the movable rod 52.
