Description

Technical Field

[0001] This utility model relates to the field of hazelnut tea processing, and in particular to a stem tip sorting device for hazelnut tea processing. Background Technology

[0002] Hazelnut tea is a healthy beverage with hazelnuts as the main ingredient, commonly found in some health-promoting teas. The process of making hazelnut tea involves roasting or frying hazelnuts, grinding them into powder, and mixing them with tea leaves or other herbs to make a tea. Hazelnuts themselves are rich in nutrients, including high-quality protein, monounsaturated fatty acids, vitamin E, and minerals such as calcium and magnesium, which have powerful antioxidant effects. In addition, hazelnuts also contain a lot of dietary fiber, which can help promote digestion and enhance immunity.

[0003] Hazelnut tea has a rich, nutty flavor with a unique taste. Its mild texture makes it an ideal everyday beverage, especially suitable for autumn and winter. It has a warming effect on the stomach, helps relieve stress and improve mood, and can also help improve skin health because its rich antioxidants help fight the aging process.

[0004] In the processing of hazelnut tea, to improve the taste, the stem tips on the surface of the hazelnuts are removed during processing to make the hazelnuts cleaner and thus improve the quality rate of the finished product. However, the traditional method of removal is to peel them manually, which is time-consuming, labor-intensive and inefficient. To address this issue, a stem tip sorting device for hazelnut tea processing is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stem tip sorting device for hazelnut tea processing, which aims to improve the problem of the traditional method of removing stem tips by manually peeling them, which is time-consuming, labor-intensive and inefficient.

[0007] The screening assembly includes a protective shell, which is fixedly connected to the outside of the outer shell. A motor is fixedly connected to the inner wall of the protective shell. A turntable is fixedly connected to the output end of the motor. A sliding frame is slidably connected to the top of the turntable. A connecting rod is fixedly connected to the rear side of the sliding frame. A screen plate is fixedly connected to the rear end of the connecting rod. Two slide rails are slidably connected to the bottom of the screen plate.

[0008] As a further description of the above technical solution:

[0009] The collection assembly includes a collection frame, two fans, and a housing. The collection frame is slidably connected to the inner wall of the housing. The fans are fixedly connected to the inner wall of the housing. The housing is fixedly connected to the front side of the housing. A spring is fixedly connected to the inner wall of the housing. A slide plate is fixedly connected to the left end of the spring. A lever is fixedly connected to the front side of the slide plate. A rod is fixedly connected to the left side of the slide plate. A stop bar is slidably connected inside the housing. A lever is fixedly connected to the front side of the stop bar.

[0010] As a further description of the above technical solution:

[0011] The connecting rod is externally slidably connected inside the protective shell, and the connecting rod is externally slidably connected inside the outer shell.

[0012] As a further description of the above technical solution:

[0013] The slide rail is fixedly connected to the inner wall of the outer casing, and the front end of the pipe is fixedly connected to the inside of the protective casing.

[0014] As a further description of the above technical solution:

[0021] The outer side of the stop bar and the outer side of the insert bar abut against each other.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the turntable is driven by a motor, which moves the slide frame back and forth. At the same time, under the support and limit of the slide rail, the connecting rod drives the screen plate to move back and forth and generate vibration, which vibrates the hazelnuts and rubs against the screen plate, thereby realizing the automatic peeling of the stem tip from the hazelnuts, saving time and effort and making the operation convenient.

[0024] 2. In this utility model, the rotating disc generates suction in the pipe, which draws the screened impurities and debris into the collection frame. In conjunction with the paddle, the sliding plate compresses the spring, causing the insert rod to retract into the housing and detach from the collection frame. At the same time, the stop bar automatically falls down to block the outlet of the insert rod, thus enabling quick disassembly and assembly of the collection frame, which facilitates the cleaning of the debris collected inside the collection frame.

[0037] Working Principle: When using this device to sort stem tips, the motor 3 drives the turntable 4 to rotate, causing the sliding frame 5 to reciprocate along the connecting rod 6. Supported by the slide rail 9, the connecting rod 6 pushes and pulls the screen plate 7, causing it to vibrate. Hazelnuts are then fed into the outer shell 1 through the feed inlet at the top of the outer shell 1. The hazelnuts automatically fall onto the screen plate 7, and the vibration of the screen plate 7 causes them to rub against each other, thus peeling off the stem tips, which fall to the bottom of the outer shell 1. The hazelnuts are then discharged from the left side of the outer shell 1, completing the sorting process. During the sorting process, the stem tips that fall into the outer shell 1 are drawn into the collection frame 13 through the pipe 11 by the airflow from the blower 14. When all the hazelnuts are collected... After the sub-sorting is completed, by moving the lever 18, the slide plate 17 is driven to compress the spring 16, causing the insertion rod 8 to retract into the housing 15 and disengage from the collection frame 13. At the same time, the stop bar 12 will automatically fall down to block the outlet of the insertion rod 8. At this time, the collection frame 13 is unlocked. Then, the collection frame 13 is taken out from the protective housing 2, and the collected stem tips inside are removed. Then, the collection frame 13 is put back into the protective housing 2. Next, the lever 10 is pulled up to disengage the stop bar 12 from the insertion rod 8. At this time, the spring 16 will instantly push the slide plate 17 to reset, causing the insertion rod 8 to pop out and insert into the collection frame 13, fixing the collection frame 13 inside the protective housing 2, thus completing the cleaning. The operation is convenient and labor-saving.
