Description

Technical Field

[0001] This invention belongs to the field of camellia oil processing technology, and particularly relates to a peeling device and method for camellia seed husks. Background Technology

[0002] Camellia oleifera Abel is an oil-producing species in the Camellia genus of the Theaceae family with high seed oil content and high production value. It is an important woody oil-producing economic tree species in southern my country. Also known as the oil tea tree or tea seed tree, it is known as one of the world's four major woody oil-producing tree species, along with olive, oil palm and coconut.

[0003] The seeds inside the camellia fruit are the raw material for extracting camellia seed oil. Because the seeds are encased in a hard pericarp, they must be removed after harvesting. Generally, the seed-to-permabrasion ratio of camellia fruit is about 1:4. The traditional method of removing the pericarp from camellia fruit involves piling the harvested fruit in indoor or outdoor drying yards for several days, then spreading them out on a sunny day to dry in the sun for several more days. The fruit will crack open on its own, and most of the seeds will come out naturally. The remaining seeds are then peeled off by hand to obtain the camellia seeds used for oil extraction. This method is inefficient.

[0004] In existing technologies, there are also methods that use camellia fruit peeling devices to peel the fruit. Most existing camellia fruit peeling devices use pressure rollers to squeeze the fruit, but the fruit can easily be crushed between the pressure rollers, which affects the peeling quality. Summary of the Invention

[0005] The present invention aims to solve at least one of the above-mentioned technical problems by providing a peeling device and method for camellia seed skin. The device cuts the outer skin of the camellia seed with a ring-shaped cutting blade and a peeling cutting blade, and separates the camellia seed from the outer skin by rotating and squeezing the ring-shaped cutting blade and the peeling cutting blade, thus avoiding the crushing of the camellia fruit and achieving a good peeling effect.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figures 1 to 3 As shown, this embodiment of the invention provides a peeling device for camellia seeds, including a main body. The main body includes an outer casing, an outer cylinder 10 fixedly or integrally disposed within the outer casing, and an inner rotating cylinder 20 disposed within the outer cylinder 10 and rotatable relative to the outer cylinder 10. An inlet 101 is provided at the top of the outer casing. A peeling channel 102 is formed between the outer cylinder 10 and the inner rotating cylinder 20. Multiple peeling cutting blades 110 that can pop outwards from the inner side of the outer cylinder 10 are provided on the inner side of the outer cylinder 10. An elastic element 120 is provided between the peeling cutting blades 110 and the mounting groove of the outer cylinder 10. The peeling cutting blades 110 are obliquely arranged from the upper end to the lower end of the outer cylinder 10 or arranged spirally. Multiple annular cutting... Blade 210: When the camellia fruit enters the peeling channel 102, the inner rotating cylinder 20 rotates relative to the outer cylinder 10, that is, the inner rotating cylinder 20 rotates circumferentially in the horizontal direction. The peeling cutting blade 110 is set obliquely or spirally. Through the relative movement of the annular cutting blade 210 and the peeling cutting blade 110, the camellia seeds in the peeling channel 102 rotate and the outer skin is cut into multiple circumferential slits. Through the rotational squeezing action of the annular cutting blade 210 and the peeling cutting blade 110, the camellia seeds are easily separated from the outer skin. The elastic element 120 gives the peeling cutting blade 110 a certain elastic force in the direction of the inner rotating cylinder 20, so as to be suitable for camellia fruits of different diameters. For camellia fruits with larger diameters, the peeling cutting blade 110 can appropriately compress the elastic element 120 to avoid the large-diameter camellia fruits being over-cut, and the peeling effect of the camellia seed skin is good.

[0023] Specifically, the inner side of the outer cylinder 10 is provided with an installation groove, the root of the peeling cutting blade 110 is floatingly disposed in the installation groove, the elastic element 120 is a spring disposed inside the installation groove, one end of the spring abuts against the bottom of the installation groove, and the other end of the spring abuts against the bottom of the peeling cutting blade 110. Multiple sets of springs can be provided, and the elasticity of the peeling cutting blade 110 is balanced.

[0024] Specifically, the mounting groove is a T-shaped groove, and the root of the peeling cutting blade 110 corresponds to a T-shaped block. The outer cylinder 10 can adopt a mating structure, that is, a structure in which the left and right half-cylinders are mated, which is convenient for processing and assembly. The peeling cutting blade 110 adopts a replaceable structure, which helps to reduce maintenance costs.

[0025] Specifically, the height of the peeling cutting blade 110 at the middle of the outer cylinder 10 is greater than the height of the peeling cutting blades 110 at both ends of the outer cylinder 10, and the inlet size of the peeling channel 102 is large, allowing camellia fruits of different diameters to be rotated and cut at different positions in the peeling channel 102. The inner rotating cylinder 20 can also be configured as a drum-shaped structure that is thicker in the middle and relatively thinner at both ends.

[0026] Specifically, a grinding device 300 is provided inside the outer casing. The grinding device 300 is located below the outer cylinder 10 and the inner rotating cylinder 20 to separate the camellia seed skin inside the cut camellia fruit.

[0027] Specifically, the grinding device 300 includes an upper grinding wheel 310 and a lower grinding wheel 320. The upper grinding wheel 310 and the lower grinding wheel 320 can be respectively connected to a drive motor. The upper grinding wheel 310 and the lower grinding wheel 320 can rotate in opposite directions or at different speeds. In this embodiment, the upper grinding wheel 310 and the lower grinding wheel 320 are arranged opposite each other and can rotate relative to each other. The facing sides of the upper grinding wheel 310 and the lower grinding wheel 320 have a wavy or toothed undulating structure. A drive motor can be installed at the bottom of the inner rotating cylinder 20 to drive the inner rotating cylinder 20 to rotate. The drive motor is connected to a controller, which can control the rotational speed, direction of rotation, and output torque of the inner rotating cylinder 20. When the inner rotating cylinder 20 is stuck, it can be rotated in the opposite direction a set number of times.

[0028] Specifically, a discharge pipe 410 may be provided below the grinding device 300, which can transport the camellia fruit with separated skins to a screening device outside the outer cylinder 10. The screening device can remove the chopped camellia fruit skins by means of blowing air or rinsing, thereby obtaining camellia seeds.

[0029] Specifically, the discharge pipe 410 may be connected to a hot air pipe, which is beneficial for removing the peel of the camellia fruit.

[0030] This invention also provides a method for peeling camellia seed husks, using the aforementioned camellia seed husk peeling device, comprising the following steps:

[0031] Camellia seeds are fed into the outer casing through the feed inlet 101. The inner rotating drum 20 rotates and cuts the outer skin of the camellia seeds through the annular cutting blade 210 and the peeling cutting blade 110. The camellia seeds are separated from the outer skin by the rotation and extrusion of the annular cutting blade 210 and the peeling cutting blade 110. When the camellia fruit enters the peeling channel 102, the inner rotating cylinder 20 rotates relative to the outer cylinder 10, that is, the inner rotating cylinder 20 rotates circumferentially in the horizontal direction. The peeling cutting blade 110 is set obliquely or spirally. Through the relative movement of the annular cutting blade 210 and the peeling cutting blade 110, the camellia seeds in the peeling channel 102 rotate and the outer skin is cut into multiple circumferential slits. Through the rotational squeezing action of the annular cutting blade 210 and the peeling cutting blade 110, the camellia seeds are easily separated from the outer skin. The elastic element 120 gives the peeling cutting blade 110 a certain elastic force in the direction of the inner rotating cylinder 20, so as to be suitable for camellia fruits of different diameters. For camellia fruits with larger diameters, the peeling cutting blade 110 can appropriately compress the elastic element 120 to avoid the large-diameter camellia fruits being over-cut, and the peeling effect of the camellia seed skin is good.

[0032] This invention provides a peeling device and method for camellia seeds. The camellia fruit enters a peeling channel 102. When the inner rotating cylinder 20 rotates relative to the outer cylinder 10 (i.e., the inner rotating cylinder 20 rotates circumferentially in the horizontal direction), the peeling cutting blade 110 is arranged obliquely or spirally. Through the relative movement of the annular cutting blade 210 and the peeling cutting blade 110, the camellia seeds rotate within the peeling channel 102, and the outer skin is cut into multiple circumferential slits. The rotational squeezing action of the annular cutting blade 210 and the peeling cutting blade 110 facilitates the separation of the camellia seeds from the outer skin. An elastic element 120 provides a certain elastic force to the peeling cutting blade 110 in the direction of the inner rotating cylinder 20, adapting to camellia fruits of different diameters. For larger-diameter camellia fruits, the peeling cutting blade 110 can appropriately compress the elastic element 120, preventing over-cutting of the large-diameter camellia fruits and resulting in a better peeling effect.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
