Description

Technical Field

[0001] The utility model relates to the technical field of tea oil processing, in particular to an oil seed screening device used for tea oil processing. Background Art

[0002] Tea oil processing, that is, the extraction process of camellia oil, is a traditional and complex process. Its raw materials mainly come from wild tea seeds in the mountains. After these tea seeds are carefully selected, they must first be dried and stir-fried and dried to remove excess moisture and retain the aroma. Then, the tea seeds are crushed into powder and further steamed to make them cooked. Next, the steamed tea seed powder is pressed into tea oil cakes. This step requires delicate operation to ensure the firmness of the tea cakes. Finally, the oil in the tea oil cakes is slowly squeezed out using traditional extrusion methods to form precious camellia oil. The entire processing process does not add any chemical materials, retaining the natural nutrients of camellia oil, such as tea polyphenols and camellia glycosides, which have significant cholesterol-lowering and anti-cancer effects. The use of oilseed screening equipment can improve screening efficiency and provide high-quality raw materials for subsequent oilseed processing.

[0003] The existing Chinese patent with announcement number CN216460021U discloses a raw material screening device for tea seed oil processing, including a screening shell, a sound insulation cover and a square frame. The front and back of the screening shell are provided with strip grooves, and the two strip grooves are movably connected to the two sides of the square frame respectively. A screening net is installed inside the square frame, and the top of the square frame is fixedly connected to the sound insulation cover. One side of the top of the sound insulation cover is fixedly connected to a slag discharge channel, one end of the slag discharge channel is fixedly connected to a filter cartridge, and the other side of the top of the sound insulation cover is fixedly connected to a feed channel. Dust covers are installed on the front and back of the screening shell.

[0004] Although the above scheme improves work efficiency, reduces labor intensity and is easy to use, the device only performs a single screening, resulting in insufficient screening effect. At the same time, the device lacks an effective reminder function when discharging oil seeds, resulting in the operator being unable to determine whether discharge is required. Therefore, it does not meet existing needs. In this regard, we propose an oil seed screening device for tea oil processing. Utility Model Content

The first screening plate 14 can be driven to reciprocate synchronously through the connection of the connecting rod 13. The first screening plate 14 will drive the slider 16 to slide synchronously on the second guide rod 15, thereby ensuring the stability of the reciprocating motion, and then the first screening of the oil seeds can be achieved, and the larger oil seeds can be screened out. The first screening plate 14 can be cleaned through the front end flap, and the oil seeds passing through the first screening plate 14 will fall into the lower end of the screening chamber 4. The first rotating shaft 9 will drive the second rotating shaft 18 through the transmission belt 17 The screw conveying rod 19 rotates synchronously, so the second rotating shaft 18 will rotate the screw conveying rod 19, which can realize the screw conveying of the oil seeds and avoid blockage during discharging. When the oil seeds are screw conveyed, they will be screened for the second time through the second screening plate 24, and the smaller oil seeds can fall into the second collecting chamber 11. The operator only needs to clean the second collecting chamber 11 regularly. The qualified oil seeds will be conveyed to the first collecting chamber 5 and fall into the collecting box 20. The weighing sensor 21 will weigh the weight of the collecting box 20 and transmit the weighing data to the PLC controller 2. The operator can set the standard value in advance. The PLC controller 2 will compare the weighing data with the preset value. When it meets the standard, the sound and light alarm 22 will be activated. The sound and light alarm 22 will emit a sound and light alarm, thereby attracting nearby operators to perform the discharging operation, and the PLC controller 2 will stop the motor 7 to avoid affecting the normal discharging.
