Description

Technical Field

[0001] The utility model belongs to the technical field of donkey-hide gelatin processing, and specifically relates to a freezing device for preparing fresh stewed donkey-hide gelatin. Background Art

[0002] As a traditional tonic, the stewing method of donkey-hide gelatin has an important impact on its quality. The preparation process of fresh stewed donkey-hide gelatin is to melt rice wine and stew it multiple times. Fresh stewed donkey-hide gelatin can reduce the dryness of donkey-hide gelatin, while achieving the effects of adjusting the taste and preserving freshness.

[0003] Patent application number CN2024112355747 discloses a preparation process for fresh stewed donkey-hide gelatin, comprising the following steps: crushing the donkey-hide gelatin and mixing it with rice wine, stewing it for 0.5-1.5 hours on high heat to soften the gelatin; stewing it for 20-40 minutes on low heat; stewing it for 20-40 minutes on low heat to melt the gelatin for the first time, and freezing it; mixing the frozen donkey-hide gelatin with rice wine, thawing it, and stewing it for the fourth time on high heat. The process is to add cloves and black plums to the water and simmer for 20-40 minutes over low heat for the fifth stew. The process is followed by a sixth stew, simmering for 20-40 minutes to achieve a second melting. Add rock sugar or erythritol to the gelatin and simmer for 20-40 minutes over low heat, stirring, until the sugar is completely dissolved. The process is followed by an eighth stew, simmering for 5-15 minutes over low heat, stirring, and finally a ninth stew, simmering until the paste is formed. Steps one through nine are all double-boiled. Freezing is a crucial step in the preparation of fresh-braised gelatin, as it can affect its taste, quality, and shelf life.

[0004] However, the existing refrigeration device has some shortcomings in the preparation of fresh stewed donkey-hide gelatin. During the repeated use of the refrigeration equipment, it is easy to produce poor sealing between the tank body and the cover plate. The cold air inside the tank body is easy to leak through the gap between the tank body and the cover plate, making it impossible to always maintain a low temperature inside the tank body, which not only increases the load of the refrigeration system, but also reduces the freezing efficiency. When the cold air is lost, a large amount of moisture will be taken away, making the fresh stewed donkey-hide gelatin dry, affecting its quality. In view of this, the present utility model is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention. Example 1

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 A freezing device for preparing fresh stewed donkey-hide gelatin includes a freezing tank 1, and also includes: a cover plate 101 detachably connected to the freezing tank 1; a sealing plug 3 fixedly connected to the cover plate 101; a sealing gasket 301 arranged on the outer wall of the sealing plug 3 and in contact with the inner wall of the freezing tank 1; an air bag 4 arranged around the freezing tank 1, wherein a sealing groove 401 for cooperating with the air bag 4 is opened on the cover plate 101, and an air inlet pipe 402 connected to the air bag 4 is provided on the freezing tank 1.

[0023] The container further comprises a receiving tray 6 which is connected in a lifting manner in the freezing tank 1 .

[0024] A sleeve 5 is fixedly connected to the freezing tank 1, and a piston disk 501 is slidably connected inside the sleeve 5. A push rod 503 is fixedly connected to the piston disk 501. One end of the push rod 503 passes through the freezing tank 1 and is fixedly connected to the receiving plate 6. A spring 502 is fixedly connected between the piston disk 501 and the inner wall of the sleeve 5. A pressing rod 505 is fixedly connected to the cover plate 101, and the pressing rod 505 is against the receiving plate 6.

[0025] A conduit 504 is fixedly connected to the sleeve 5, and the air bag 4 is connected to the sleeve 5 through the air inlet pipe 402. The freezing tank 1 is provided with an air outlet pipe 403 connected to the air bag 4. The air outlet pipe 403 and the air inlet pipe 402 are both provided with solenoid valves, and the conduit 504 and the air inlet pipe 402 are both provided with one-way valves.

[0026] When in use, first remove the cover plate 101 installed on the freezing tank 1. At this time, the compressed spring 502 generates a thrust to push the piston plate 501 to slide upward in the sleeve 5, and absorb external air into the sleeve 5 through the conduit 504. At the same time, when the piston plate 501 slides upward, the push rod 503 can push the receiving plate 6 to move upward synchronously, so that the receiving plate 6 is pushed out of the freezing tank 1, thereby helping the staff to place the fresh stewed donkey-hide gelatin semi-finished product to be frozen on the receiving plate 6. After placing the fresh stewed donkey-hide gelatin First, the cover 101 is installed on the freezing tank 1, and then the freezing tank 1 is closed. During the closing process, the cover 101 can push the receiving tray 6 downward by pressing the rod 505, so that the receiving tray 6 is pushed into the freezing tank 1, thereby freezing and cooling the fresh stewed donkey-hide gelatin semi-finished product. At this time, the sealing plug 3 inserted in the freezing tank 1 squeezes the sealing gasket 301 and fits tightly with the inner wall of the freezing tank 1, thereby increasing the sealing performance of the connection between the cover 101 and the freezing tank 1, and preventing the cold air in the freezing tank 1 from passing through the cover 1 01 and the freezing tank 1 have leakage. At the same time, when the holding plate 6 moves downward, the push rod 503 can push the piston plate 501 to slide downward in the sleeve 5 and compress the spring 502. It should be noted that since the gas can be compressed, the gas temporarily stored in the sleeve 5 will not interfere with the downward movement of the piston plate 501. Then the solenoid valve on the air inlet pipe 402 is opened. At this time, the compressed gas in the sleeve 5 can be quickly filled into the air bag 4 through the air inlet pipe 402, thereby expanding the air bag 4. At the same time, the expanded air bag 4 fits tightly with the sealing groove 401, further increasing the sealing performance of the connection between the cover plate 101 and the freezing tank 1, thereby effectively preventing the loss of cold air inside the freezing tank 1, thereby keeping the temperature inside the tank at a lower level at all times, which not only reduces the load on the refrigeration system and reduces energy consumption, but also improves the freezing efficiency. At the same time, reducing the loss of cold air can reduce the humidity change of the air in the tank, effectively preventing water loss, thereby maintaining the fresh taste and rich nutritional components of the product.

[0027] When the fresh stewed donkey-hide gelatin semi-finished product needs to be taken out of the freezing tank 1, the solenoid valve on the air outlet pipe 403 is first opened to allow the gas to be discharged from the air bag 4 through the air outlet pipe 403, and then the cover 101 installed on the freezing tank 1 is removed. At this time, the compressed spring 502 generates thrust, pushing the piston disc 501 to slide upward in the sleeve 5. When the piston disc 501 slides upward, it can push the receiving plate 6 to move upward synchronously through the push rod 503, so that it pushes the receiving plate 6 out of the freezing tank 1, thereby helping the staff to take the frozen fresh stewed donkey-hide gelatin semi-finished product. Example 2

Furthermore, a semiconductor refrigeration sheet 2 is fixedly connected to the inner wall of the freezing tank 1, and a temperature controller 201 and a temperature sensor 202 are provided on the cover plate 101. The sensing end of the temperature sensor 202 passes through the freezing tank 1, and the temperature sensor 202 and the semiconductor refrigeration sheet 2 are electrically connected to the temperature controller 201.

[0029] Refrigeration mode of freezing tank 1:

[0030] The donkey-hide gelatin placed in the freezing tank 1 can be frozen and cooled by the semiconductor refrigeration chip 2. When the temperature in the freezing tank 1 reaches the value set by the temperature controller 201, the semiconductor refrigeration chip 2 can stop working. At the same time, the temperature inside the freezing tank 1 can be monitored in real time through the temperature sensor 202. When the temperature sensor 202 senses that the temperature inside the freezing tank 1 is higher than the standard value set by the temperature controller 201, the semiconductor refrigeration chip 2 can be turned on by the temperature controller 201 to continue freezing and cooling the donkey-hide gelatin in the freezing tank 1, so as to avoid long-term continuous freezing that may cause damage to the nutritional components of the freshly stewed donkey-hide gelatin. Example 3
