Description

Technical Field

[0001] The invention relates to the technical field of donkey-hide gelatin manufacturing, and in particular to a device and method for determining the degree of cleanliness of donkey hide, a raw material of donkey-hide gelatin, based on turbidity. Background Art

[0002] Donkey hide gelatin is a traditional blood tonic in my country. It is a solid gelatin made from donkey hide, an equine animal, through decoction and concentration. Its main components are protein and its hydrolyzate polypeptides, amino acids, etc. Donkey hide gelatin has many health benefits such as promoting hematopoiesis, resisting fatigue, and enhancing memory. Its production process requires 49 processes, mainly including soaking, blanching, scraping, cutting, blanching, melting, foaming, concentration, condensation, airing, and post-processing.

[0003] In the donkey skin, the raw material of donkey gelatin, donkey oil, donkey meat, donkey fascia and other substances will inevitably remain in the donkey skin during the donkey slaughter process, causing the donkey skin to rot and deteriorate during storage. Therefore, in the traditional process of donkey gelatin production, it is necessary to refer to the "blanching meat" method before the donkey skin is skinned. The production staff uses boiling water to "blanch the skin" based on their experience to blanch the insoluble substances in the donkey skin due to corrosion. The existing technology cannot completely prevent these substances from being brought into production, so it will cause the insoluble matter in donkey gelatin to be unstable, affecting the product quality. Summary of the invention

[0004] The present invention proposes a device and method for judging the degree of blanching of donkey hide, a raw material of donkey-hide gelatin, based on turbidity, which solves the problem that the existing technology in the related art cannot completely avoid bringing this part of matter into production, thus causing instability of the insoluble matter in donkey-hide gelatin water and affecting product quality.

[0059] S1. Put the cut and washed raw donkey skin into a steaming ball, and set the turbidity standard of the washed donkey skin to 60NTU;

[0060] S2, after adding water to the steaming and spheronizing machine 1, the equipment is turned on and the temperature is increased for blanching. After blanching, the machine is stopped, the first drain valve 5 and the first control valve 6 are opened, and the turbidity is automatically measured by the turbidity detection member 11, which is recorded as the first blanching. After the detection is completed, the third control valve 8 is opened to discharge the turbid liquid;

[0061] S3, then add an equal amount of water to the steaming ball steaming machine 1 for blanching, and drain the water, and measure the turbidity of the blanching water. The turbidity of the blanching water decreases from 3000±500NTU to less than 100NTU as the number of blanching increases;

[0062] S4. When the turbidity of the blanching water drops below 100 NTU, continue blanching for 2-3 times. At this time, the turbidity of the blanching water is less than the set turbidity standard value of 60 NTU and no longer changes. At this time, it is determined that the donkey hide in the steam spheronization machine 1 has been blanched clean.

[0063] Optionally, the steam spheronization machine 1 in S2 is heated to 50-80° C., and the blanching time is 5-10 min.

[0064] Optionally, the turbidity detection element 11 adopts a photometric 90° scattering method with a resolution of 0.1 NTU and a detection range of 0-4000 NTU.

[0065] Optionally, the algorithm of the turbidity detection element 11 is: turbidity = log10, where I0 is the incident light intensity, and I is the transmitted light intensity scattered by blanching water.

[0066] The device for determining the degree of blanching of donkey hide, a raw material of donkey-hide gelatin, of the present invention realizes accurate control and monitoring of the blanching process of donkey hide through key components such as a spheronizing machine 1, a turbidity detection device 2, a turbid liquid pipeline 3, and a water flow pipeline 4. The spheronizing machine 1 in the device is responsible for blanching the donkey hide, while the turbidity detection device 2 receives the turbid liquid after blanching and the supplemented clean water through the first water outlet and the second water outlet, respectively. The setting of the turbid liquid pipeline 3 and the water flow pipeline 4 ensures the continuity and controllability of the blanching process. The optional control valve and drain valve further enhance the flexibility of the device and the convenience of operation. The addition of the temperature detection component 10 and the turbidity detection component 11 enables the device to monitor the water temperature and turbidity in real time, and intuitively display them through the PLC display 12, thereby improving the accuracy and reliability of the operation. The setting of the heat exchanger 13 effectively adjusts the temperature of the blanching water and ensures the stability of the blanching effect. In addition, the equipment uses the photometric 90° scattering method for turbidity detection, with a resolution of up to 0.1NTU and a detection range of 0-4000NTU, ensuring the accuracy of the test results. Through the integration of these technologies, this equipment can effectively determine the degree of blanching of donkey hide, the raw material of donkey hide gelatin, and improve the quality and efficiency of donkey hide gelatin production. The turbidity detection equipment can be cleaned by opening the second control valve and the fourth control valve to avoid measurement errors caused by incomplete blanching last time.

[0067] The method for determining the degree of blanching of donkey hides, a raw material of donkey-hide gelatin, using the present device mainly comprises the following steps: First, in step S1, the cut and cleaned raw donkey hides are put into the steaming and spheronizing machine 1, and the standard of the turbidity of the donkey hides is set to 60NTU. Then, in step S2, an appropriate amount of water is added to the steaming and spheronizing machine 1, the equipment is turned on and the temperature is raised to 50-80°C, and the blanching treatment is performed, and the blanching time is 5-10 minutes. After the blanching is completed, the machine is stopped and the first drain valve 5 and the first control valve 6 are opened, and the turbidity of the blanched water is automatically measured by the turbidity detection element 11, and recorded as the first blanching. After the detection is completed, the third control valve 8 is opened to discharge the turbid liquid. In step S3, an equal amount of water is added to the steaming and spheronizing machine 1 for blanching, and the water is drained, and the turbidity of each blanching water is measured. As the number of blanching increases, the turbidity of the blanching water should be gradually reduced from 3000 ± 500NTU to less than 100NTU. Finally, in step S4, when the turbidity of the blanching water is reduced to less than 100NTU, continue to blanch for 2-3 times. At this time, if the turbidity of the blanching water is less than the set turbidity standard value of 60NTU and no longer changes, it is determined that the donkey skin has been blanched. During the whole process, the turbidity detection part 11 of the equipment adopts the photometric 90° scattering method to ensure the accuracy and reliability of the test results. Through this method, the degree of blanching of the donkey skin of the donkey-hide gelatin raw material can be effectively determined, and high-quality raw materials can be provided for the production of donkey-hide gelatin. The turbidity detection equipment can be cleaned by opening the second control valve and the fourth control valve to enter the clean water to avoid the impact of unclean cleaning on the detection accuracy.

[0068] Put the donkey hide that has been cut and washed into the blanching steaming ball, and set the standard of turbidity of the donkey hide to 60NTU; add water to the steaming ball, turn on the steaming ball and steam to blanch the hide, stop the machine after washing for the specified time, and open the drain valve of the steaming ball to automatically drain the water; at this time, the inlet valve of the blanching water turbidity detection device is interlocked with the drain valve of the steaming ball and opened, and the blanching water passes through the drainage pipe, passes through the heat exchanger 13 for cooling, and enters the detection tank through the inlet valve of the device. When the liquid level in the detection tank reaches 60cm (over the turbidity detection probe), the inlet valve of the device is closed, and the turbidity detection probe starts to detect that the turbidity of the blanching water in the detection tank is 2000NTU; after waiting for 3 minutes, the drain valve of the detection tank is automatically opened to empty the blanching water in the tank, and wait for the next blanching water detection. Add equal amounts of water to the steaming ball for blanching the donkey hides several times. The blanching water detection device automatically repeats the above steps of "water collection-detection-discharge", measures the turbidity of the blanching water and outputs the change curve of the turbidity of the blanching water; until the thirteenth blanching and rinsing, the turbidity of the blanching water is measured to be 55NTU, which is lower than the limit of 60NTU. It is considered that the donkey hides are blanched clean, and the steaming ball is used to dissolve the hides after rinsing again. The final quality inspection result shows that the water-insoluble matter of the donkey hide gelatin refined from this batch of donkey hides is 1.12%, which meets the standard.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
