Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment, this embodiment provides a preparation process of freeze-dried roxburghii tea, comprising:

[0036] A. Raw material preparation: Select fresh, pest-free, and appropriately mature roxburghii as raw material, wash the roxburghii and remove dust and impurities on the surface;

[0037] B. Slicing and core removal are carried out simultaneously: after the washed roxburghii is thorned, a slicing and core removal machine is used as a processing equipment, the slicing and core removal machine has a conveyor and a slicing and core removal component, the conveyor conveys the roxburghii laterally, and the slicing and core removal component is reciprocated downwardly pressed to perform batch slicing and core removal, so as to facilitate subsequent drying treatment;

[0038] Slicing and core removal are carried out simultaneously, which on the one hand ensures that the hard core of the sea buckthorn is removed during the slicing process to improve the taste and quality of the product; on the other hand, it improves processing efficiency.

[0039] C. Pre-freezing treatment: Put the cut roxburghii slices into a freezing device for pre-freezing treatment;

[0040] Vacuum freeze drying: Place the pre-frozen sea buckthorn slices into a vacuum freeze dryer for vacuum freeze drying; during the drying process, the vacuum degree, temperature and drying time must be controlled to ensure that the moisture in the sea buckthorn slices is directly sublimated in the form of ice crystals, thereby retaining the nutrients and flavor of the sea buckthorn.

[0041] It should be noted that in the freeze-drying step, the degree of drying is controlled: after drying to eight points, the temperature is slowly raised to 30℃-40℃ under vacuum until the slices are completely dry.

[0042] D. Seasoning: According to taste requirements, add an appropriate amount of xylitol or other sweeteners to the dried roxburghii slices and rub them so that the sweeteners are evenly attached to the roxburghii slices; this can integrate the bitter taste of the roxburghii and improve the taste of the product;

[0043] The seasoned roxburghii slices are vacuum packed to extend the shelf life of the product and maintain the flavor of the product;

[0044] E. Quality inspection and storage: Conduct quality inspection on freeze-dried roxburghii tea, including appearance, taste, nutritional content and other indicators to ensure that product quality meets the standards;

[0045] Store the qualified freeze-dried sea buckthorn tea in a cool, dry, well-ventilated environment, avoiding direct sunlight, high temperature and humidity.

[0046] Meanwhile, the slicing and de-coring machine in the slicing and de-coring synchronous step includes a body 1, such as Figure 1 As shown, an inverted L-shaped support frame 11 is extended upward from the side of the machine body 1, and a slicing and core removal component is adjustable on the inner top wall of the inverted L-shaped support frame 11. The slicing and core removal component is built into the machine body 1. A conveying component is also provided on the machine body 1. The slicing and core removal component is located above the conveying component and can perform a reciprocating downward cutting action. The slicing and core removal component is used for core removal and slicing synchronously. In the process of preparing roxburghii tea, the method of slicing and core removal synchronously is adopted, which solves the problem of first core removal, repeated positioning and then slicing in the prior art, which consumes man-hours and affects the preparation efficiency.

[0047] Specifically as follows, first solve the problem of automatic transportation of roxburghii, such as Figure 1 and Figure 5 As shown, the transmission component has a plurality of transmission plates 21 hinged to each other to form a closed transmission chain plate and two I-shaped rollers 2 wound around the two ends of the inner side of the closed transmission chain plate. The machine body 1 is provided with a mounting notch for rotatably mounting the two I-shaped rollers 2, and a plurality of support rollers for rolling and supporting the transmission plate 21 are also rotatably arranged in the mounting notch. A mounting shell is arranged on the side of the end of the outer wall of the machine body 1, and a motor is built in the mounting shell. The output end of the motor passes through the side wall of the machine body 1 and is connected to the end of one of the I-shaped rollers 2 to provide rotational power for it. The other I-shaped roller 2 rotates in coordination, so that the entire closed transmission chain plate can be unidirectionally cyclically transmitted, so as to achieve the purpose of continuously and automatically transmitting the roxburghii laterally.

[0048] In order to prevent the roxburghii from falling or rolling during the transportation process, a plurality of positioning support blocks 3 are further provided on the upper end surface of the transmission plate 21, a hollow sleeve 31 is fixed on the upper end surface of the positioning support block 3, and a plurality of sharp spike heads 32 are fixed on the edge position of the upper end surface of the hollow sleeve 31. Figure 5As shown, the stalk of the sea buckthorn or the other end opposite to the stalk is placed on multiple sharp spikes 32 on the hollow sleeve 31. The sharp spikes 32 can penetrate into the sea buckthorn fruit to ensure that the sea buckthorn is stable on the hollow sleeve 31 and is not caused to roll or fall due to the lateral transmission of the transmission component, affecting the slicing and core removal operation.

[0049] It should be noted that if Figure 6 As shown, the multiple spike heads 32 are arranged at different heights. Under the premise of not affecting the positioning restriction of the sea buckthorn fruit, the outer wall of the sea buckthorn fruit is lowered and simultaneously contacts the multiple spike heads 32 to increase the insertion resistance.

[0050] In addition, if Figure 2 and Figure 3 As shown, the slicing and core removal component includes a plurality of core spiral slices 4, two core spiral slices 4 form a group, the two core spiral slices 4 are relatively distributed, the outer walls of the two core spiral slices 4 are fixed with L-shaped hanging frames 41, and a transmission disk 42 is fixed between the upper ends of the two L-shaped hanging frames 41, a transmission frame 6 is sleeved between the radial outer walls of the plurality of transmission disks 42, a tooth block 62 is provided on the inner side wall of the transmission frame 6, and an annular tooth groove is provided on the radial side wall of the transmission disk 42, and the tooth block 62 is meshed with the annular tooth groove, and a longitudinal sliding block 62 is provided on the longitudinal side wall of the inverted L-shaped support frame 11 The inverted L-shaped support frame 11 is provided with a cavity, and a motor 1 is provided in the cavity. The output end of the motor 1 rotates through the longitudinal slide groove and is fixedly connected to a transmission wheel 63. The transmission wheel 63 is tilted away from the axis direction of the output end. A linkage plate 61 is fixed to the outer wall of the transmission frame 6. The bottom wall of the linkage plate 61 is provided with a receiving notch for accommodating the transmission wheel 63. The transmission wheel 63 rotates with the output end of the motor 1 as the rotation center, and can push the linkage plate 61 to move back and forth horizontally in the receiving notch. The tooth block 62 pushes the transmission disk 42 to rotate forward and backward. At the same time, a hydraulic cylinder is fixed to the upper end surface of the inverted L-shaped support frame 11. The telescopic end of the hydraulic cylinder slides through the top wall of the inverted L-shaped support frame 11 and is horizontally fixed with a crossbeam 47. The upper end surface of the transmission disk 42 is rotatably provided with a connecting rod 46, and the connecting rod 46 is fixedly connected to the bottom wall of the crossbeam 47.

[0051] like Figure 2 and Figure 4 As shown, the slicing and core removal component also includes a cutter 5, which is provided with multiple pieces. A docking block 52 is fixed between the ends of two adjacent cutters 5, and a gap is provided between the two adjacent cutters 5; the cutter 5 located in the middle is provided with a disconnection port 51, and the side wall of the disconnection port 51 is fixedly welded to the outer wall of the nuclear rotating slice 4.

[0052] The same group of two core rotary slicers 4 rotate to form an annular rotary cutting space for accommodating the prickly pear core. When slicing and core removal are synchronously processed, the hydraulic cylinder is used to provide telescopic power, and all the transmission disks 42 are driven to descend synchronously through the crossbeam 47 and the plurality of connecting rods 46, so that the core rotary slicer 4 is lowered in height through the L-shaped hanging frame 41 to contact the prickly pear passing by. As the hydraulic cylinder is continuously stretched, the multi-piece cutter 5 first contacts the prickly pear, and the multi-piece cutter 5 can cut down to slice the prickly pear, and then the core rotary slicer 4 can penetrate into the fruit along the prickly pear stalk or the end opposite to the prickly pear stalk. At the same time, the motor 1 provides rotational power to drive the transmission wheel 63 to push the linkage plate 61 to move back and forth horizontally in the accommodating gap for adjustment, and then the tooth block 62 of the transmission frame 6 is used to push the transmission disk 42 to rotate forward and backward. The same group of two core rotary slicers 4 rotate to form an annular rotary cutting space, which can cut off the prickly pear core with rapid reciprocating rotation. During the rotation of the core slicer 4, not only the core of the roxburghii is removed, but also the sliced ​​fruit is separated and falls onto the transmission plate 21, and is laterally transmitted to the next process along the transmission plate 21.

[0053] It should be noted that, in order to ensure uninterrupted power, a vertically distributed connecting block is also slid through the longitudinal slot and fixed at one end of the crossbeam 47, and the connecting block is fixedly connected to the motor housing, so that the motor, the transmission frame 6, and the nuclear rotary slicer 4 are synchronously raised and lowered to achieve uninterrupted transmission. In this way, the rotary core removal and slicing processes are synchronously and effectively carried out.

[0054] In this embodiment, in order to avoid the residual prickly pear kernel between the two kernel slices 4 of the same group, a sliding sleeve 44 is slidably provided on the outer wall of the L-shaped hanging frame 41, a counterweight column 43 is fixed between the two sliding sleeves 44, and a top rod 45 capable of being inserted into the annular peeling space is provided on the bottom wall of the counterweight column 43. Figure 3 As shown, the core spiral slice 4 penetrates into the fruit and separates the core from the fruit after rotary cutting, and then the hydraulic cylinder contracts, raising the core spiral slice 4, which is easy to bring up the roxburghii core, which remains between the two core spiral slices 4, affecting the de-coring process again. Then during the de-coring process, when the core spiral slice 4 penetrates into the fruit, the counterweight column 43 will be pushed up, and when the core spiral slice 4 is raised, the counterweight column 43 falls under its own weight, and the roxburghii core is pushed out by the push rod 45, so as to perform the de-coring process again.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
