[0002] Donkey-hide gelatin promotes hematopoiesis, increases red blood cell counts, white blood cell counts, and platelet counts, and improves symptoms of blood deficiency, such as sallow complexion, dizziness, and palpitations. It can also treat coughs and dry throats caused by lung yin deficiency or damage to lung yin caused by pathogenic dryness. It also acts as a coagulator and stops bleeding, making it effective for treating various bleeding symptoms, including hematemesis, hematuria, hematochezia, and metrorrhagia.

The enzymatic hydrolysis equipment for donkey-hide gelatin products according to claim 4, characterized in that: A mounting block (628) is fixedly connected to the upper side of the cover plate (601), and a spring (627) is fixedly connected between the mounting block (628) and the first guide block (625).

6. The enzymatic hydrolysis equipment for donkey-hide gelatin products according to claim 3, characterized in that: The limiting plate (646) is arranged in an arc-shaped structure.

7. The enzymatic hydrolysis equipment for donkey-hide gelatin products according to claim 1, characterized in that: A fixing cover (602) is fixedly connected to the upper side of the cover plate (601), and a connection hole (603) is provided on the front side of the fixing cover (602).

8. The enzymatic hydrolysis equipment for donkey-hide gelatin products according to claim 1, characterized in that: The movable ring (615) is slidably connected to the feed pipe (5).

9. A method for using the enzymatic hydrolysis device for donkey-hide gelatin products according to any one of claims 1 to 8, characterized in that: The specific steps include: S1. First, donkey-hide gelatin and enzyme are put into the enzymolysis tank (1) through the feeding pipe (5), and water is added to the heating chamber (4), and the electric heating rod (7) is started to heat the material in the tank. When the enzymolysis is carried out, the handle (619) is turned to control the rotation of the screw (617). Under the action of the moving ring (615), the control plate (613), the control block 1 (611), the turntable (610) and the rotating rod (609), the multiple blocks (607) are controlled to rotate, so that the blocks (607) and the card slots (606) are used in conjunction with each other, so that the upper side of the cover plate (601) is pressed down to limit the position, thereby preventing external air from entering the tank, and providing an oxygen-free environment for the enzymolysis; S2. When the moving ring (615) rises at the same time, under the action of the side block (620), the stop plate (621) and the pulley (636), the seesaw (634) is controlled to rotate. Under the action of the rotating block 2 (633), the linkage plate (632), the moving block (630), the connecting rod (629), the guide block 1 (625) and the moving plate (626), the tooth plate (648) is controlled to move backward, so that the tooth plate (648) drives the gear (623) to rotate. Under the action of the connecting plate (622), the rotating shaft (637), the control plate (638), the control block 2 (639), the connecting plate (640) and the fixed plate (643), the limit plates (646) on the left and right sides are controlled to approach the sealing ring (605), so that the inner side of the cover plate (601) is limited to prevent external air from easily entering the enzymatic hydrolysis tank (1).
