Description

Technical Field

[0001] The invention relates to a method for rubbing the skin of Torreya grandis berries. Background Art

[0002] Torreya grandis is a beloved nut, but processing it is complex, particularly peeling the green husk. Currently, peeling is done manually, which is inefficient and costly. This is especially true when purchasing large quantities of nut. Manual peeling is too slow, leading to the nuts rotting and being discarded.

[0003] In order to improve the peeling efficiency of Torreya grandis, semi-automatic Torreya grandis peelers are available on the market. However, this type of peeler has defects: during the impact peeling process, the disordered impact force will damage the eyes of the Torreya grandis, causing the Torreya grandis kernels to be eroded by decay bacteria during the composting process, affecting the flavor and quality of the Torreya grandis, and even the toxic substances in it will affect human health.

[0004] The utility model patent application number 202220954104.6 discloses a "Chinese torreya peeling mechanism", which uses a pair of parallel peeling rollers to squeeze and peel the Chinese torreya fruit. The spacing between the peeling rollers is larger than the size of the kernel and smaller than the size of the Chinese torreya fruit. This structure of the Chinese torreya peeling mechanism still has the following defects: First, the spacing of its peeling rollers is not suitable for larger or smaller Chinese torreya fruit. The kernels of larger Chinese torreya fruit will be crushed by the peeling rollers, and the green skin of smaller Chinese torreya fruit cannot be peeled off by the peeling rollers; second, the peeling of the Chinese torreya fruit by squeezing the peeling rollers not only causes greater or lesser damage to the kernels, but also does not peel cleanly; third, it can only be used for Chinese torreya fruit whose skin is already ripe, and is not suitable for Chinese torreya fruit whose green skin is tightly adhered to the kernel. Summary of the Invention

[0005] The invention aims to provide a method for rubbing the skin of torreya nut, which is suitable for rubbing the skin of immature torreya nut, especially suitable for torreya nut with the skin and kernel tightly adhered to the torreya nut, and is also suitable for rubbing the skin of mature torreya nut. In particular, the torreya nut skin rubbing method of the invention can be used to rub the skin of torreya nut; the kernel of the torreya nut will not be broken, and the eyes at both ends of the torreya nut are beneficial to protecting the torreya nut, ensuring the integrity of the torreya nut kernel, and facilitating late fermentation; and continuous and fully automatic rubbing of the torreya nut is achieved.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A method for rubbing the skin of Torreya grandis berries comprises the following steps:

[0008] Step 1: Distribution of Torreya grandis

[0009] The torreya nuts to be rubbed enter the distributing device from the discharger at the bottom of the silo under the action of gravity. The distributing device sends the single upright torreya nuts into the torreya nuts clamping and rotating device. The torreya nuts clamping and rotating device vertically clamps the torreya nuts through the upper and lower pressure heads and drives the torreya nuts to rotate around the axis of the upper and lower pressure heads.

[0010] Step 2: Grind the middle part of the Torreya grandis

[0011] The flexible peeling device for gnawing green fruit moves toward the gnawing green fruit under the action of the feed drive assembly, and the rotating peeling device at the front end of the flexible peeling device for gnawing green fruit contacts with the rotating gnawing green fruit to complete the peeling of the middle section of the gnawing green fruit. After completing the peeling of the middle section, the flexible peeling device for gnawing green fruit retreats backward under the action of the feed drive assembly;

[0012] Step 3: Grind the lower part of the Torreya grandis

[0013] The centering lifting assembly moves downward, so that the flexible peeling device for gnawing green fruit is obliquely aligned with the lower section of gnawing green fruit. The flexible peeling device for gnawing green fruit moves toward the lower section of gnawing green fruit under the action of the feed drive assembly. The rotating peeling device contacts the rotating lower section of gnawing green fruit to complete the peeling of the lower section of gnawing green fruit. After completing the peeling of the lower section, the flexible peeling device 2 for gnawing green fruit retreats backward under the action of the feed drive assembly.

[0014] Step 4: Grate the skin of the upper part of the Torreya grandis

[0015] The centering lifting assembly moves upward, and at the same time, the rubbing wheel support seat rotates 180 degrees under the action of the rubbing reversing assembly. Subsequently, the flexible rubbing device for gnawing green fruit moves toward the upper section of the gnawing green fruit under the action of the feed drive assembly. The rotating rubbing device 201 contacts the rotating upper section of the gnawing green fruit, completing the rubbing of the upper section of the gnawing green fruit. The flexible rubbing device for gnawing green fruit that has completed the rubbing of the upper section moves backward under the action of the feed drive assembly.

[0016] Step 5: Remove the middle, lower and upper sections of the fruit after removing the torreya grandis.

[0017] The lifting cam drives the rotating disk upright rod to move upward to drive the upper pressure head to move upward. At the same time, the steering support shaft fixed on the rotating disk upright rod slides in the inclined groove of the base to rotate the upper pressure head rotating disk by a preset angle, so that the center of the upper pressure head and the center of the guide locator are separated. Then the guide locator rotates by a preset angle to make the Chinese torreya fruit slide out in an inclined state, and the guide locator returns to its original position, so that the next Chinese torreya fruit can enter smoothly in this state.

[0018] Step 6: Reset and adjust

[0019] The guide locator returns to its original position so that the next Torreya grandis fruit can enter smoothly in this state, and the above steps are repeated.

[0022] A leather scraper rotating sleeve is provided between the leather scraper and the leather scraper supporting shaft. The outer periphery of the leather scraper is provided with a plurality of friction knives, and the cutting edges of the friction knives are arc-shaped.

[0023] The leather scraper has a leather scraping reversing assembly, which includes: a leather scraper reversing driver, a sliding sleeve, a leather scraping wheel support seat, and a drive shaft base. The inner ring of the leather scraper reversing driver is connected to the leather scraping wheel support seat, the upper side of the sliding sleeve is connected to the drive shaft base, and the lower side of the sliding sleeve is connected to the outer ring of the leather scraper reversing driver, so that the upper side and the lower side of the sliding sleeve can absorb the displacement generated by the leather scraping wheel support seat and the drive shaft base during feed drive by sliding on the sliding positioning surface, and the sliding positioning surface serves as a rotation-stopping surface to prevent the outer ring of the leather scraper reversing driver and the drive shaft base from generating circumferential relative movement.

[0024] The leather scraper has the centering lifting assembly, which includes: a rack mounting frame, a centering lifting rack, a centering lifting drive gear, a drive shaft base, a connecting seat, a lifting drive, a lifting drive wheel, a right driving wheel, a left driving wheel, a right driving shaft, a left driving shaft, and the centering lifting rack is arc-shaped, and the curvature of the arc is the average curvature of the outer surface of multiple Torreya grandis fruits.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: due to the adoption of the above technical scheme, the Torreya grandis green fruit clamping and rotating device can keep the Torreya grandis green fruit upright and rotate in the initial state, and the rotating peel grater at the front end of the Torreya grandis green fruit flexible peel grating device contacts the rotating Torreya grandis green fruit, and can sequentially complete the peel grating of the middle, lower and upper sections of the Torreya grandis green fruit. This method utilizes rotary friction to scrape off the green peel of the Torreya grandis green fruit, avoiding the defect of crushing the Torreya grandis kernel. It is suitable for scraping the peel of immature Torreya grandis green fruit, especially for Torreya grandis green fruit whose green peel is tightly adhered to the kernel, and is also suitable for scraping the peel of mature Torreya grandis green fruit; since the upper and lower skins of the Torreya grandis green fruit are pressed by the upper and lower pressure heads respectively, the peel grater will not scrape off the upper and lower skins, which well protects the Xishi eyes at both ends of the Torreya grandis, ensures the integrity of the Torreya grandis kernel, and is beneficial to the later fermentation of Torreya grandis.

[0026] A further beneficial effect is that the method for rubbing the skin of the ginkgo nuts is equipped with a plurality of ginkgo nuts rubbing devices evenly distributed around the edge of the rotary disk, and the material dividing device can automatically and sequentially deliver the ginkgo nuts to be rubbed into each ginkgo nuts clamping and rotating device, thereby realizing continuous and fully automated rubbing of the ginkgo nuts.

[0027] A further beneficial effect is that the setting of the first and second double buffer pads can control the pressure applied to the gnaphalium nut by the peel grater to not be too great. When the pressure is too great, the first and second buffer pads can absorb the displacement caused by the retreat of the gnaphalium nut flexible peel grater through double deformation, thereby better protecting the gnaphalium nut kernel from being scratched by the peel grater.
