TECHNICAL FIELD
[0001] The present application relates to the technical field of testing or analyzing materials by optical means, i.e., by infrared light, visible light, or ultraviolet light, and in particular to a device for predicting the moisture and protein content of whiting surimi. BACKGROUND
[0002] After production, the internal moisture and protein of whiting surimi need to be analyzed and detected, and the prediction device utilizes the characteristic absorption of near-infrared light and molecular functional groups to realize rapid and non-destructive detection of the moisture and protein content of whiting surimi by establishing a quantitative model of spectral data and chemical analysis values. The prediction device can complete spectral collection, data processing, and result output for samples, and the technical inspiration for the prediction device is as follows: The following problems are found in the research on the prediction device: The prediction device places the processed whiting surimi in a sample box and then collects the spectrum of the whiting surimi in the sample box by near-infrared light to form non-destructive detection. However, the processed whiting surimi is prone to stratification, and there are problems of uneven distribution of fiber structure and moisture, which can cause spectrum collection deviation. Therefore, the prediction device cannot utilize the buoyancy of the internal moisture of the whiting surimi sample to form secondary mixing of the whiting surimi sample during the detection process, and electronic components are avoided during mixing to avoid the volatilization of moisture due to temperature rise during homogenization. Currently, the prior art with the publication number CN102353644A discloses a near-infrared spectroscopy method for rapidly and simultaneously detecting the moisture and protein content of ribbonfish surimi. The detection process only takes about 1 minute, while the direct drying method or the Kjeldahl method needs to be continued for more than 4 hours. This method can be applied in fish surimi production factories. The invention is suitable for whiting surimi with a moisture content of 73.97% to 80.05% and a protein content of 10.39% to 17.14%, which is consistent with the common moisture and protein content range of whiting surimi on the market.

[0020] Beneficial effects: 1. The sealing cover is movably nested with the sample box, and the stirring frame is in the interior of the sample box. Since the outer blades are arranged on the upper and lower sides of the clamping ring, a weight difference is generated between the two sides of the clamping ring. When the outer blades enter the interior of the sample box, the weight difference between the two sides of the clamping ring and the buoyancy of the sample water in the interior of the sample box can assist the outer blades in rotating in a vertical direction in the interior of the sample box. The outer blades can drive the lower end of the sample box to move upwards, so as to avoid the stratification of the saithe surimi in the interior of the sample box, and to avoid the deviation of the probe in collecting the spectrum by using infrared light due to the uneven distribution of the moisture and protein of the saithe surimi. 2. When the outer blade rotates in a vertical direction, the upper end of the outer side of the inner ring is movably connected with the outer blade in a vertical direction, so that the outer blade forms vertical extrusion on the outer side of the upper end of the inner ring. The inner ring moves in a vertical direction through the elastic sheet, and the inner ring can move back in a vertical direction by using the elastic force of the elastic sheet. During the repeated movement of the inner ring in a vertical direction, the inner ring can drive the moisture and protein of the saithe surimi in the interior of the sample box to flow in a vertical direction. 3.The inner ring can form a return extrusion on the outer side of the outer blade during the repeated movement in the vertical direction, thereby assisting the rotation of the outer blade again, and through the matching use of the inner ring and the outer blade, after the sample box is placed in the groove of the detector, the inner ring in the sample box can be matched with the stirring frame at the lower end of the sealing cover, thereby assisting the full mixing of the water and protein on the outer side of the sample box, and without the need for electronic equipment to mix the water and protein of the pollack surimi, the situation of water evaporation caused by the temperature rise in the sample box during homogenization can be avoided; 4.When the bearing is moved in the vertical direction by the inner ring, the inner blade and the bent ring use the buoyancy of the sample water in the sample box, the bent ring is rotated in the vertical direction by the sleeve ring II, and the inner blade is rotated outside the bearing by the sleeve ring I, so that the inner blade can mix the sample in the inner ring, and the inner ring and the stirring frame are matched to fully mix the sample in the sample box, thereby facilitating the probe to collect multiple position spectra of the sample box inside by infrared light, and increasing the data accuracy during probe collection; 5.Meanwhile, the inner blade generates an upward force during rotation, and since the bearing is vertically inclined, the sleeve ring I is vertically inclined and slides upward outside the bearing, when the inner blade slides to one side of the bent ring due to the driving of the sleeve ring I, the bent ring is arc-shaped and has an arc angle of 45-90°, and the bent ring can extrude to one side of the inner blade during rotation to assist the upward return sliding of the inner blade, so that the inner blade can slide and mix in the vertical inclined direction outside the bearing during rotation, thereby forming full mixing at multiple angles.

DETAILED DESCRIPTION
[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0033] Embodiment: As shown in the accompanying Figure 1 to the accompanying Figure 10 illustrations: Embodiment 1: A device for predicting the moisture content and protein content of pollock surimi, comprising an analyzer 1, the top of the analyzer 1 is hingedly connected with a top cover 101 through a hinge, the inner wall of the top cover 101 is provided with a probe 102, the inside of the analyzer 1 is provided with a detector 103, the upper end of the detector 103 is movably nested with a sample box 2; The sample box 2 is correspondingly arranged in a vertical direction with the probe 102, the upper end of the detector 103 is provided with a groove, and the sample box 2 is movably nested in the groove; The probe 102 is internally provided with a tungsten halogen lamp, which serves to provide stable near-infrared light; The front of the analyzer 1 is provided with a display screen, and the display screen and the probe 102 are both connected with the detector 103 through an electric wire in a loop, and the detector 103 is used for converting the near-infrared light signal carrying sample information into an electric signal, and then converting it into a digital form through an A-D converter for output; The analyzer 1 is a near-infrared spectrum analyzer; The upper end of the sample box 2 is movably nested with a sealing cover 201, and the sealing cover 201 is made of acrylic material; Wherein: Pollock surimi is mixed with water, and the pollock surimi is processed into a gel sample and placed inside the sample box 2. The top cover 101 is manually closed. Then, the probe 102 collects the spectrum of the pollock surimi sample inside the sample box 2 with infrared light under the same instrument parameters as the calibration model. The detector 103 inputs the spectrum to be measured into the validated PLS model, and the instrument automatically outputs the moisture and protein content. Example 2: The upper end of the sealing cover 201 is provided with a stirring rack 202, and the outer side of the stirring rack 202 is provided with partitions 203. The side of the stirring rack 202 near the partitions 203 is surrounded by retaining rings 3, and the two sides of the retaining rings 3 are provided with outer blades 301. The stirring rack 202 is spring-shaped, the partitions 203 are arranged vertically, and there are 4-6 partitions 203. The number of retaining rings 3 is matched with the number of partitions 203. When the sealing cap 201 is nested and docked with the sample box 2, the stirring rack 202 is inside the sample box 2. The stirring rack 202 is spring-shaped, which can increase the contact area between the stirring rack 202 and the sample inside the sample box 2. The partitions 203 are arranged vertically, and there are 4-6 partitions 203. By setting the partitions 203, the retaining rings 3 on the outside of the mixing rack 202 can be separated, so as to prevent the retaining rings 3 from accumulating at the lower end of the mixing rack 202 due to their own weight. The retaining ring 3 is arranged in a circular shape, with outer blades 301 located on the upper and lower sides of the retaining ring 3 respectively. The sides of the outer blades 301 are arc-shaped, and the overall arc is "W"-shaped. Please refer to the instruction manual for details. Figure 7 As shown; Since the outer blades 301 are located on the upper and lower sides of the retaining ring 3 respectively, the weight of the outer blades 301 on the retaining ring 3 on both sides of the retaining ring 3 is different, resulting in a weight difference on both sides of the retaining ring 3. When the outer blades 301 and the retaining ring 3 enter the sample box 2, the weight difference on both sides of the retaining ring 3 and the buoyancy of the sample moisture inside the sample box 2 can be used to assist the outer blades 301 to rotate vertically inside the sample box 2. Wherein: the sealing cap 201 is nested and connected with the sample box 2. At this time, the stirring rack 202 is inside the sample box 2. Since the outer blades 301 are located on the upper and lower sides of the retaining ring 3 respectively, a weight difference is generated on both sides of the retaining ring 3. When the outer blades 301 and the retaining ring 3 enter the sample box 2, the weight difference on both sides of the retaining ring 3 and the buoyancy of the sample water inside the sample box 2 can be used to assist the outer blades 301 to rotate vertically inside the sample box 2. The outer blades 301 are arc-shaped on the side, and the arc is "W" shaped. The outer blades 301 can drive the sedimented sample at the lower end of the sample box 2 to move upward, avoiding the situation that the pollock paste is easy to separate into layers inside the sample box 2. This avoids the situation that the probe 102 will deviate when collecting the spectrum using infrared light due to the uneven distribution of water and protein in the pollock paste. In the embodiment 3, the lower end of the sample box 2 is provided with the base 4, the upper end of the base 4 is elastically connected with the elastic sheet 401, the end of the elastic sheet 401 is elastically connected with the inner ring 402, the inner side of the inner ring 402 is distributed with the sleeve 5, and the side of the sleeve 5 away from the inner ring 402 is rotationally connected with the bearing 501; The elastic sheet 401 is arranged in the vertical direction, every two elastic sheets 401 form a group, the elastic sheet 401 is provided with 4-5 groups, and the inner ring 402 is elastically moved in the vertical direction through the elastic sheet 401.
