Description

Technical Field

[0001] The present invention relates to the technical field of donkey-hide gelatin detection, and in particular to a donkey-hide gelatin content detection device and a use method thereof. Background Art

[0002] Donkey hide gelatin is a food and medicine ingredient with the functions of nourishing yin and replenishing blood, and is a good tonic for autumn and winter. The main way to eat donkey hide gelatin is to boil it with rice wine, add black sesame seeds, walnut kernels, etc., and process it into donkey hide gelatin cake for consumption. However, when making donkey hide gelatin cake, if the donkey hide gelatin component is too little, it will also damage the rights and interests of consumers. After searching, the Chinese patent publication number CN118393010B discloses a donkey hide gelatin content detection device, including: a transmission mechanism, an equal amount of water release mechanism, a dissolving mechanism, a pushing mechanism, an adsorption mechanism, a weighing mechanism and a component detection mechanism. When quantitative donkey hide gelatin content detection of donkey hide gelatin cake is carried out, the donkey hide gelatin content detection device is used. The method for dissolving gelatin in water is as follows: a certain amount of donkey-hide gelatin cake is put into a dissolving mechanism, then a motor A is started to drive an equal amount of water discharge mechanism to discharge a certain amount of hot water into the dissolving mechanism for the first time, the mesh plate moves up and down to dissolve the donkey-hide gelatin cake, and walnuts and other impurities are filtered out, then the equal amount of water discharge mechanism discharges clean water into the second layer of the dissolving mechanism to wash the impurities, and ensure that the impurities no longer contain donkey-hide gelatin, then, an adsorption mechanism is used to adsorb the impurities, and it is again ensured that there is no donkey-hide gelatin on the impurities, then, a weighing mechanism is used to measure the donkey-hide gelatin, and finally, a component detection mechanism is used to detect the content of the main amino acid index components in the donkey-hide gelatin.

[0003] Although the above technical solution does not require human intervention, saves manpower and prevents human errors, the added donkey-hide gelatin cake cannot be weighed during use. It needs to be weighed with the help of external weighing equipment and the donkey-hide gelatin is dissolved by up and down vibration. The dissolution speed is slow, which reduces work efficiency. It is also necessary to use adsorption paper to absorb all the water on the impurities. The adsorption paper cannot fully contact the impurities, resulting in some water and donkey-hide gelatin residues, which will affect the detection accuracy. Moreover, the above technical solution is relatively cumbersome to operate, and it is necessary to enter dissolution, filtration, adsorption and weighing in sequence before calculation and detection can be performed, which further reduces work efficiency.

8. A method for using a donkey-hide gelatin content detection device, comprising the donkey-hide gelatin content detection device according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1. First, the donkey-hide gelatin cake to be tested is placed in the support cylinder (55) of the weighing and dissolving mechanism (5), and the weight of the donkey-hide gelatin cake can be automatically weighed by the first weighing sensor (52); S2, sequentially starting the dust-proof water-adding mechanism (7), the crushing mechanism (6), and the annular heating plate (56) in the weighing and dissolving mechanism (5); the crushing mechanism (6) can be operated to crush the donkey-hide gelatin cake; the dust-proof water-adding mechanism (7) can add water thereto and spray the debris and dust generated during the crushing to reduce dust so as not to affect the accuracy; the annular heating plate (56) can heat the inside, thereby increasing the dissolution speed of the donkey-hide gelatin cake and further increasing the work efficiency; and during the water-adding process, the water volume can be measured and monitored by the provided flow meter (711); S3, after the dissolution is completed, the sealing cover (854) is opened, and then the second motor (511) is started, so that the dispensing pipe (59) can be extended into the interior of the filter frame (85), and then the control valve (510) is opened to allow the dissolved donkey-hide gelatin solution to flow into the interior of the filter frame (85), and then the sealing cover (854) is closed; S4, starting the fifth motor (86) in the centrifugal filtering mechanism (8) to drive the filter frame (85) to rotate, thereby performing solid-liquid centrifugal separation on the donkey-hide gelatin solution, and the filtered liquid will fall into the collection frame (93) through the liquid outlet pipe (83), and the mass of the solution can be weighed by the second weighing sensor (91); S5.
