[0028] The following is combined with Figure 1-3 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0029] like Figure 1-3 As shown, the spice extraction device for spice processing provided by the present invention includes a cylinder body 101 and a power device 102, and also includes: a planetary gear system, a conical fixed grinding disc 107, a plurality of transmission shafts 105, a plurality of conical movable grinding discs 108 and a plurality of spoilers 109, wherein the ring gear 103 of the planetary gear system is connected to the cylinder body 101, and the sun gear 104 of the planetary gear system is connected to the power device 102; a plurality of transmission shafts 105 are vertically arranged, and each transmission shaft 105 is connected to a planetary gear 106 of the planetary gear system; the conical fixed grinding disc 107 is arranged at the bottom of the cylinder body 101; a plurality of conical movable grinding discs 108 are all abutted against the conical fixed grinding disc 107, and each conical movable grinding disc 108 is connected to a transmission shaft 105; a plurality of spoilers 109 are arranged in the cylinder body 101, and each spoiler 109 is connected to a conical movable grinding disc 108, and the spoiler 109 is used to stir the liquid in the cylinder body 101.
[0030] The working principle of the above embodiment is briefly described:
[0031] When the device is in use, the spice raw material is added into the cylinder 101, and then the extractant is poured into the cylinder 101. The power device 102 is turned on, and the power device 102 drives the sun gear 104 of the planetary gear system to rotate, thereby driving the multiple planetary gears 106 of the planetary gear system to revolve around the sun gear 104 and rotate on their own. Each planetary gear 106 drives the transmission shaft 105 connected thereto to revolve and rotate on its own, thereby driving the conical moving grinding disc 108 to rotate on its own and rotate around the conical fixed grinding disc 107. Since the conical moving grinding disc 108 abuts against the conical fixed grinding disc 107, the conical moving grinding disc 108 squeezes the conical fixed grinding disc 107, and at the same time, the conical moving grinding disc 108 is staggered with the conical fixed grinding disc 107, so the conical movable grinding disc 108 and the conical fixed grinding disc 107 squeeze and knead the raw materials between them, which can improve the grinding effect of the whole device on the raw materials, and then improve the wall breaking rate of the raw materials, and the conical movable grinding disc 108 can drive the spoiler 109 to rotate while rotating, so as to stir the liquid in the cylinder body 101, and can mix the raw materials at the bottom of the cylinder body 101 more evenly in the extractant, improve the uniformity of the raw materials in the extractant, and further improve the grinding effect of the raw materials.
[0032] The spice extraction device for spice processing of the present invention can squeeze and knead the raw materials, thereby fully breaking the walls of the raw materials, and fully stir the raw materials in the extractant, thereby improving the uniformity of the raw materials in the extractant, improving the extraction rate of the raw materials, and thus improving the utilization rate of the raw materials.
[0033] On the basis of the above embodiments, in order to further improve the grinding and kneading effect of the entire device on the raw materials, the utilization rate of the raw materials is further improved.

A cam groove 202 is provided on the inner wall of the cylinder body 101. A slider 203 is slidably connected in the cam groove 202, and a connecting frame 204 is connected to the slider 203. Each transmission shaft 105 is pivotally connected to the connecting frame 204, and the connecting frame 204 can apply a vertical force to the transmission shaft 105. When multiple transmission shafts 105 revolve around the sun gear 104, the multiple transmission shafts 105 drive the connecting frame 204 to rotate. Under the action of the cam groove 202, the slider 203 drives the multiple transmission shafts 105 to reciprocate in the vertical direction through the connecting frame 204.
[0035] When the multiple transmission shafts 105 revolve around the sun gear 104, the multiple transmission shafts 105 drive the connecting frame 204 to rotate, thereby driving the slider 203 to slide in the cam groove 202. Under the action of the cam groove 202, the slider 203 drives the connecting frame 204 to reciprocate in the vertical direction. Since the connecting frame 204 can apply a vertical force to the transmission shaft 105, the connecting frame 204 drives the multiple transmission shafts 105 to reciprocate in the vertical direction. The transmission shaft 105 drives the conical movable grinding disc 108 to reciprocate in the vertical direction, so that the distance between the conical movable grinding disc 108 and the conical fixed grinding disc 107 changes reciprocatingly, thereby not only stirring the liquid in the cylinder body 101, but also applying a reciprocating extrusion force to the raw materials mixed in the liquid, thereby further improving the grinding and kneading effect of the entire device on the raw materials, thereby further improving the utilization rate of the raw materials.

The transmission shaft 105 drives the conical movable grinding disc 108 to rotate through the first special-shaped hole, and the conical movable grinding disc 108 rotates on itself and rotates around the conical fixed grinding disc 107, thereby grinding the raw materials between the conical movable grinding disc 108 and the conical fixed grinding disc 107, and as the telescopic mechanism 201 drives multiple transmission shafts 105 to reciprocate in the vertical direction, the conical movable grinding disc 108 on each transmission shaft 105 slides in the vertical direction at the bottom end of the transmission shaft 105, and when the stopper 3 on the transmission shaft 105 contacts the conical movable grinding disc 108, the stopper 3 drives the conical movable grinding disc 108 to move upward, so that the conical movable grinding disc 108 can intermittently contact the conical fixed grinding disc 107, so that the raw materials are intermittently kneaded and diffused, thereby further improving the grinding and kneading effect of the entire device on the raw materials, thereby further improving the utilization rate of the raw materials.

Under the action of the elastic force of the spring 4, the bottom end of the conical moving grinding disc 108 abuts against the block 3 or the conical surface of the conical moving grinding disc 108 abuts against the conical surface of the conical fixed grinding disc 107. By providing the spring 4, when the multiple transmission shafts 105 reciprocate in the vertical direction, the spring 4 always applies a vertical downward elastic force to the conical moving grinding disc 108. Under the action of the elastic force of the spring 4, the conical moving grinding disc 108 slides in the vertical direction at the bottom end of the transmission shaft 105, and the compression amount of the spring 4 changes, so that the grinding force applied by the conical moving grinding disc 108 and the conical fixed grinding disc 107 to the raw material gradually changes, thereby further improving the grinding and kneading effect of the entire device on the raw material, thereby further improving the utilization rate of the raw material.
