Description

Technical Field

[0001] The invention relates to a method for controlling a donkey-hide gelatin foam extraction and pre-leaching process based on infrared thermal imaging temperature measurement, and belongs to the field of donkey-hide gelatin extraction. Background Art

[0002] Donkey hide gelatin is a traditional Chinese blood tonic. It is a solid gelatin made from donkey hides (equids) through a process of decoction and concentration. Its main components are proteins, their hydrolyzed products, peptides, and amino acids. Donkey hide gelatin has various health benefits, including promoting hematopoiesis, combating fatigue, and enhancing memory. Its production process involves 49 steps, including soaking, washing, shaving, cutting, blanching, softening, foaming (pre-rinsing), concentration, condensation, gelatin drying, and post-processing.

[0003] The properties of donkey-hide gelatin in the "Chinese Pharmacopoeia" are described as: "This product is in the form of rectangular blocks, square blocks or cubes. It is brown to dark brown and shiny. It is hard and brittle, with a shiny cross-section. The fragments appear brown and translucent when viewed in light. It has a faint odor and a slightly sweet taste." Consumers generally believe that the properties of high-quality donkey-hide gelatin are "black as lacquer, translucent as amber, hard and brittle, with a shiny cross-section."

[0004] Therefore, the transmittance, which indirectly reflects the impurity content in donkey-hide gelatin, can be used as a trait standard for judging the quality of donkey-hide gelatin, and the impurities in donkey-hide gelatin that cannot be effectively filtered out are mainly removed by the foaming (pre-leaching) process. Summary of the Invention

[0005] In order to overcome the defects of the prior art, the present invention provides a method for controlling the pre-rinsing process of donkey-hide gelatin foaming based on infrared thermal imaging temperature measurement. The technical solution of the present invention is:

[0006] A method for controlling the pre-rinsing process of donkey-hide gelatin foaming based on infrared thermal imaging temperature measurement comprises the following steps:

[0007] S1, after the separated glue liquid is pumped into the foaming machine, the steam heating valve is opened to steam heat the glue liquid in the foaming machine, and the temperature of the glue liquid in the foaming machine is monitored using an infrared thermal imaging thermometer;

[0008] S2. After the glue liquid in the foaming machine is heated to boiling by steam, the foaming machine alarm prompts that it is ready to proceed to the foaming step. At this time, the infrared thermal imaging thermometer performs the first temperature detection on the glue liquid;

[0009] S3. After normal temperature water with a flow rate of 1.5±1 m / s is pumped into the glue liquid in the foaming machine, the phase equilibrium between impurities and protein solution in the glue liquid is destroyed, causing water-insoluble impurities to precipitate and float on the surface of the glue liquid. When the impurities completely cover the surface of the glue liquid, foaming is performed. At this time, the infrared thermal imaging thermometer performs a second temperature measurement on the glue liquid.

[0010] S4, repeat step S3 several times. After the foaming is completed, manually adjust the steam heating valve according to the boiling state of the glue liquid to make the glue liquid enter the pre-rinsing stage of slight boiling. At this time, the infrared thermal imaging thermometer performs a third temperature detection on the glue liquid;

[0011] S5. The emulsion phase of the glue liquid that has entered the micro-boiling stage in the foam extractor is destroyed due to the boiling state, which further causes impurities to precipitate and float on the surface of the glue liquid. At this time, the infrared thermal imaging thermometer detects the temperature of the insoluble matter on the surface of the glue liquid;

[0012] S6. With the opening and closing of the steam valve of the foaming machine, the foaming machine is in the heating or stopping state. When the steam valve is opened, the temperature of the impurities floating on the surface of the glue liquid is detected by an infrared thermal imaging thermometer. The temperature will also change with the degree of heat. When the temperature of this part of the impurities is higher than 100℃, it means that the steam valve of the foaming machine is in the closed state. When the temperature of this part of the impurities is lower than 50℃, it means that the steam valve of the foaming machine is in the closed state.

[0013] In the step S2, when the first temperature detection is performed, the temperature of the glue solution is 90°C-100°C.

[0014] In the step S3, when the second temperature detection is performed, the temperature of the glue solution is reduced from 90°C-100°C to 60°C-70°C.

[0015] In the step S4, when the third temperature detection is performed, the temperature of the glue solution is 70°C-90°C.

[0016] In the step S5, the temperature of the insoluble matter on the surface of the glue solution is 60°C-70°C.

[0017] In step S4, step S3 is repeated 5-25 times.

[0018] The advantages of the present invention are: the process of foaming and pre-rinsing donkey-hide gelatin is controlled by infrared thermal imaging temperature measurement technology, and the temperature parameter is incorporated into the process of foaming and pre-rinsing donkey-hide gelatin for the first time, which is conducive to the uniformity and stability of the production process; the process of foaming and pre-rinsing is tracked by infrared thermal imaging temperature measurement technology, and the temperature can be digitized as an important process parameter of the process, laying the foundation for realizing digital and intelligent control of the process of foaming and pre-rinsing.
