Abstract
Description
Technical Field
[0001] This utility model relates to the field of peony deep processing technology, and in particular to a peony seed crushing and oil pressing equipment. Background Technology
[0002] After flowering, peonies produce pentagonal pods containing seeds about the size of corn kernels. Peony seed oil, extracted from peony seeds, is rich in nutrients such as protein, fat, minerals, and vitamins, as well as antioxidants such as anthocyanins and flavonoids, giving it high medicinal and health benefits.
[0003] For peony seed oil producers, the current problem is that existing oil presses lack a crushing function, and peony seeds are directly fed into the press, resulting in a low oil yield. Furthermore, most existing oil presses use screw pressing, which makes the screws difficult to clean and results in incomplete separation of oilseeds and residue. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model discloses a peony seed crushing and oil pressing device, the purpose of which is:
[0005] 1. Add crushing function to increase oil yield;
[0006] 2. To completely separate the slag from the oil.
[0007] Specifically, the present invention adopts the following technical solution:
[0008] A peony seed crushing and oil pressing device includes:
[0009] The crushing unit includes a crushing bucket, inside which a pair of toothed rollers for crushing peony seeds are provided;
[0010] The bagging unit includes a screw conveyor, and a cloth bag is provided at the output end of the screw conveyor. The screw conveyor is used to transport the crushed peony seeds into the cloth bag.
[0011] The oil pressing unit has a pair of pressing rollers for squeezing the cloth bag.
[0012] To further improve the technical solution, toothed cutters are arranged in a circumferential array on the roller surface of the toothed roller, and the inclination direction of the toothed cutters is consistent with the rotation direction of the toothed roller.
[0013] The technical solution was further improved so that the two toothed rollers rotate in the same direction.
[0014] In a further improved technical solution, the screw conveyor is horizontally positioned below the crushing hopper, and the feed inlet of the screw conveyor is connected to the discharge outlet of the crushing hopper.
[0015] To further improve the technical solution, the cloth bag is rolled up and fitted onto the output end of the screw conveyor, and a baffle is installed at the output end of the screw conveyor.
[0016] A further improved technical solution involves a pair of oil pressing rollers arranged vertically, with an oil receiving box located below the pair of oil pressing rollers.
[0017] After implementing the above technical solution, the beneficial effects of this utility model compared to the prior art are:
[0018] This peony seed crushing and oil pressing equipment has a crushing unit, which has the advantages of high crushing efficiency and small crushing particle size compared with the existing toothed roller crusher.
[0019] This peony seed crushing and oil pressing equipment also has a bagging unit. The bagging unit can put the crushed peony seeds into a cloth bag. During oil pressing, the residue remains in the cloth bag and the oil flows out of the cloth bag, which can completely separate the residue from the oil.
[0020] This peony seed crushing and oil pressing equipment can crush peony seeds before oil pressing, effectively improving the oil yield. Attached Figure Description

[0026] A peony seed crushing and oil pressing device includes a crushing unit, a bagging unit, and an oil pressing unit. Its structure and function are described in detail below.
[0027] See attached document Figure 1 and attached Figure 2 , attached Figure 1 This diagram shows the overall structure of the peony seed crushing and oil pressing equipment. Figure 2 The attached image shows the attached image. Figure 1 A partial schematic diagram along the P-direction. (Attached) Figure 1 and attached Figure 2 As can be seen, the crushing unit includes a crushing bucket 1, and a pair of toothed rollers 2 for crushing peony seeds are arranged inside the crushing bucket 1. The structure of the toothed rollers 2 is existing technology. On the roller surface of the toothed rollers 2, toothed cutters are arranged in a circumferential array, and the inclination direction of the toothed cutters is consistent with the rotation direction of the toothed rollers 2.
[0028] See attached document Figure 3 , attached Figure 3 The diagram shown is of an existing toothed roll crusher. (See attached diagram.) Figure 3 As can be seen, existing toothed roll crushers also have a pair of toothed rolls 2, but the rotation directions of the pair of toothed rolls 2 are opposite. Existing toothed roll crushers mainly compress materials and are primarily used for crushing brittle and hard materials, such as stones and ores.
[0029] This crushing unit reverses the right-side toothed roller 2 and changes its rotation direction. Due to the change in the rotation direction of the pair of toothed rollers 2 and the tilt direction of the toothed cutters, during operation, the toothed cutters on one toothed roller 2 move downwards within the crushing area, while the toothed cutters on the other toothed roller 2 move upwards, forming a shearing structure. Therefore, this crushing unit primarily shears materials and is mainly used for crushing materials with low hardness and high moisture content, such as plant seeds. Compared to existing toothed roller crushers, this crushing unit has higher crushing efficiency and smaller particle size.
[0030] The bagging unit includes a screw conveyor 3, which is horizontally positioned below the crushing hopper 1. The feed inlet of the screw conveyor 3 is connected to the discharge outlet of the crushing hopper 1. A cloth bag 4 is installed at the output end of the screw conveyor 3. The cloth bag 4 can be made of canvas or non-woven fabric. During operation, the screw conveyor 3 transports the crushed peony seeds into the cloth bag 4. Placing the crushed peony seeds in the cloth bag 4 ensures that the residue remains inside the bag during oil extraction, allowing for complete separation of the residue from the oil.
[0031] To accommodate the longer fabric bag 4, the fabric bag 4 is rolled up and fitted onto the output end of the screw conveyor 3. In addition, a baffle 5 is provided at the output end of the screw conveyor 3. The function of the baffle 5 is to block the rolled-up part of the fabric bag 4 and prevent the fabric bag 4 from falling off the screw conveyor 3.
[0032] The oil pressing unit includes a pair of vertically arranged oil pressing rollers 6, with an oil collecting box 7 located below them. During operation, one oil pressing roller 6 rotates clockwise, while the other rotates counter-clockwise. A cloth bag 4 containing crushed peony seeds passes between the rollers 6. By controlling the distance between the two rollers 6, the crushed peony seeds can be pressed to obtain peony seed oil. Because the rollers 6 are vertically arranged, the pressed peony seed oil drips along the rollers 6 into the oil collecting box 7. Furthermore, since the residue remains inside the cloth bag 4, it does not fall into the collecting box 7, thus improving the purity of the peony seed oil. After rinsing away the residue, the cloth bag 4 can be reused.
[0033] As described above, this peony seed crushing and oil pressing equipment has a crushing unit, which, compared to existing toothed roller crushers, has the advantages of high crushing efficiency and small particle size. This peony seed crushing and oil pressing equipment also has a bagging unit, which can pack the crushed peony seeds into a cloth bag 4. During oil pressing, the residue remains inside the cloth bag 4, while the oil flows out, allowing for complete separation of the residue and oil.
[0034] The parts not detailed herein are prior art. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of protection of which is defined by the appended claims and their equivalents.
