Description

Technical Field

[0001] The utility model relates to the technical field of donkey-hide gelatin production equipment, in particular to a sealed rolling extraction device for donkey-hide gelatin juice. Background Art

[0002] Sealed rolling extraction is a method for extracting donkey-hide gelatin juice from donkey skin. In this operation process, the processed donkey skin is placed in a clean container, sealed, and extracted with hot water by rolling. During sealed rolling extraction, the skin material is always in motion in the extraction container. It adopts the countercurrent movement of the skin material and the gelatin-extracting hot water, and mass transfer and heat transfer occur during the continuous and slow movement between the solid and liquid phases, causing the collagen in the skin material to be heated together with water, and the collagen is hydrolyzed. When a certain degree is reached, the gelatin juice is discharged, and the hair residue is removed, thus completing the entire gelatin-extracting process. The advantages of this method are as follows: First, it improves work efficiency. The new sealed extraction process reduces the cumbersome procedures such as repeated water inlet, heating, and juice discharge, shortens the extraction time, and improves work efficiency. It is more than 30 times more efficient than skin melting in an open pot. Second, it saves raw materials. Skin melting in an open pot takes dozens of hours and still cannot completely extract all the collagen components in the true skin layer, and collagen can be found in the residue. During the process of skin melting and gelatin extraction with the new sealed juice extraction process, the container is constantly rotating, making the skin material relatively loose in the extraction container, thus increasing the contact between the solid and liquid phases, facilitating the improvement of heat transfer and hydrolysis rate, and all the collagen components contained in the true skin layer can be converted into gelatin juice in a relatively short time, improving the yield of donkey-hide gelatin. The residue discharged from the container is all hair residue, broken epidermis, subcutaneous layer, and broken internal parts. Third, it improves working conditions. During the process of skin melting at normal pressure in an open pot, operations such as feeding, picking up the skin, grabbing the pot, pressing the hair, and discharging the residue are all strenuous physical labor, and the workshop is filled with steam, resulting in a poor production environment. After adopting the new sealed juice extraction process, except for the feeding operation that has not been mechanized yet, the rest of the work is completed by the rotation of the container, greatly reducing the labor intensity. At the same time, the workshop environment has also been greatly improved.

[0003] Sealed rolling extraction adopts an integrated sealed design. When discharging the residue after the extraction is completed, some high-temperature gelatin juice adsorbed in the residue gushes out rapidly along with the residue. At this time, the gushing hot liquid may splash onto the staff, causing harm to the staff. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a sealed rolling extraction device for donkey-hide gelatin juice that can overcome or at least partially solve the above problems.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] An apparatus for hermetically rolling extraction of donkey-hide gelatin juice, comprising: a rotating extraction drum, further comprising: a nozzle, fixedly arranged on one side of the extraction drum; a sealing ring, hermetically rotating on the nozzle; a plurality of filter holes, circumferentially formed on the nozzle, and the filter holes communicate with the sealing ring; a frame body, arranged under the extraction drum; a controller, fixedly arranged on the frame body; a drain pipe, fixedly arranged under the sealing ring; a solenoid valve, arranged in the drain pipe; a hose, arranged at the drain end of the drain pipe.

[0007] Preferably, two groups of support blocks are symmetrically and fixedly connected to the frame body. A rotating shaft is rotatably arranged on the support blocks. Two ends of the rotating shaft are symmetrically and fixedly connected with support columns, and the support columns are in contact with the extraction drum. A motor is fixedly connected to the frame body. An output end of the motor is fixedly connected with a gear. A toothed ring is fixedly connected to the extraction drum, and the toothed ring meshes with the gear. A limiting ring matching the extraction drum is fixedly connected to the frame body.

[0008] Preferably, a partition board is fixedly connected to one side of the extraction drum. A feed inlet is arranged on the partition board. A spiral blade is arranged on one side of the partition board close to the nozzle.

[0009] In order to facilitate guiding of donkey skin, further, a plurality of guiding blades matching the spiral blades are arranged in the extraction drum.

[0010] In order to facilitate large-amplitude tumbling of donkey skin, further, a plurality of groups of inclined blocks are fixedly connected in the extraction drum.

[0011] In order to facilitate improving the extraction effect of donkey skin, further, a connecting shaft is fixedly connected between the partition board and the extraction drum, and a plurality of convex blocks are fixedly connected to the connecting shaft.

[0012] Compared with the prior art, the present utility model provides an apparatus for hermetically rolling extraction of donkey-hide gelatin juice, having the following beneficial effects:

[0013] 1. The sealed rolling extraction device for donkey-hide gelatin juice controls the rotation of the extraction drum through a motor. The donkey hide enters the extraction drum along the spiral sheet through the feed inlet, and then hot water is added into the extraction drum through an external water addition mechanism. The rotation of the extraction drum causes the donkey hide to turn over inside the extraction drum, thereby effectively extracting the donkey hide. When it is necessary to discharge the residue of the donkey hide after extraction, an external collection frame is placed under the nozzle, and then the controller controls the motor to turn over. The motor drives the extraction drum to turn over through the gear and the toothed ring. At this time, the extraction residue inside the extraction drum moves towards the feed inlet along the plurality of guide sheets and is then discharged from one side of the spiral sheet. At the same time, the controller controls the solenoid valve to open, and the donkey-hide gelatin juice entering the nozzle is discharged into the sealing ring through the filter holes and finally discharged along the drain pipe and the hose, thereby effectively preventing the hot donkey-hide gelatin juice from splashing and causing harm to the staff.

[0014] 2. The sealed rolling extraction device for donkey-hide gelatin juice rotates the extraction drum to make the donkey hide inside tumble. At this time, the vertical side of the inclined block drives the donkey hide upward, and then the donkey hide drops again, so that it has a certain dropping space, thereby effectively improving the extraction effect of the donkey hide. At the same time, when part of the donkey hide drops and contacts the connecting shaft, the donkey hide is rubbed by the convex block, thereby effectively improving the extraction effect of the donkey hide.

[0015] Parts not involved in this device are the same as the prior art or can be implemented by using the prior art. The utility model effectively prevents the hot donkey-hide gelatin juice from splashing and causing harm to the staff, and effectively improves the extraction effect of the donkey hide.

Two ends of the rotating shaft 102 are symmetrically and fixedly connected with support columns 103, and the support columns 103 are in contact with the extraction drum 2. A motor 106 is fixedly connected to the frame 1. An output end of the motor 106 is fixedly connected with a gear 107. A toothed ring is fixedly connected to the extraction drum 2, and the toothed ring meshes with the gear 107. A limit ring 104 matching the extraction drum 2 is fixedly connected to the frame 1.

[0023] A partition 207 is fixedly connected to one side of the extraction drum 2. A feed inlet 208 is arranged on the partition 207. A spiral blade 209 is arranged on a side of the partition 207 close to the material nozzle 201.

[0024] A plurality of guide vanes 210 matching the spiral blade 209 are arranged in the extraction drum 2.

[0025] When pre-processing and extracting donkey skin, place the donkey skin at the nozzle 201. Control the extraction drum 2 to rotate through the motor 106. The donkey skin enters the extraction drum 2 along the spiral piece 209 through the feed inlet 208. Then, add hot water into the extraction drum 2 through an external water adding mechanism. Rotate the extraction drum 2 to make the donkey skin tumble inside the extraction drum 2, so as to effectively extract the donkey skin. When it is necessary to discharge the donkey skin residue after extraction, place an external collection box under the nozzle 201, and then control the motor 106 to turn over through the controller 105. The motor 106 drives the extraction drum 2 to turn over through the gear 107 and the tooth ring.

At the same time, when part of the donkey skin drops and contacts the connecting shaft 3, the donkey skin is rubbed by the convex blocks 301, thereby effectively improving the extraction effect of the donkey skin.
