Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solution of the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled person without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a material crushing and screening apparatus according to an embodiment of the present invention.

As shown in fig. 1, the utility model provides a material crushing and screening device, the device includes: a first crusher 1, a first vibrating screen 31, a second vibrating screen 32 and a second crusher 2. First rubbing crusher 1 and second rubbing crusher 2 all are used for smashing the material, and the shale shaker is used for the screening to smash the back and has the not unidimensional material.

For convenience of explanation, the material in the embodiment of the present invention is dried gardenia. The dried gardenia fruit comprises peel and nutlet, and the utility model mainly aims to select the fruit grains with high nutlet content and low peel content. Of course, in other embodiments, the material includes any lumps that are separated by different precision mills and different mesh size shakers.

Generally, the fruit peels of the gardenia dried fruits wrap the nuts, the total content of the fruit peels is lower than that of the nuts, and the density of the fruit peels is far lower than that of the nuts, so that the quality of the fruit peels under the same size is lower than that of the nuts, and the fruit peels, the nuts and the fruit particles (the nuts with the fruit peels) can be separated through different physical or chemical properties of the fruit peels, the nuts and the fruit particles. For example, the peel and the kernel can be blown apart by a fan, but a centrifuge can be used to separate the peel, the kernel and the fruit particles with different densities. For example, because the peel is coarser than the kernels and grains, the peel, kernels and grains can be initially separated by gluing and rolling.

A pulverizer is a machine that pulverizes a large-sized solid raw material to a desired size. The pulverizer may be classified into a coarse pulverizer, a pulverizer, and an ultra-fine pulverizer according to the size of the pulverized or crushed material. For convenience of explanation, the pulverizer of the embodiment of the present invention includes only the coarse crusher and the pulverizer. Of course, in other embodiments, different precision mills may be used to grind different materials.

The external force applied to the solid in the crushing process comprises four kinds of shearing, impacting, rolling and grinding. The shearing is mainly used for coarse crushing (crushing) and crushing operation, and is suitable for crushing or crushing operation of tough or fibrous materials and large materials; the impact is mainly used in the crushing operation and is suitable for crushing the brittle materials; the rolling is mainly used in high-fineness grinding (ultramicro grinding) operation and is suitable for ultramicro grinding operation of most of materials; the grinding is mainly used for ultramicro grinding or ultra-large grinding equipment and is suitable for further grinding operation after grinding operation. The utility model provides a crushing process mainly relates to cut, strike and roll. Of course, if the hardness of the material is too high, grinding can also be used to crush the material.

Preferably, the fruit peel wraps the kernels, so that for large-size dried fruits, the large-size dried fruits can be screened by adopting vibrating screens with different sizes, each dried fruit falls into the cutting groove, the two ends of each dried fruit are cut off, the skins of the dried fruits are integrally cut off by the circular or square ring cutter, the dried fruits are separated into the fruit peel with the kernels and the square kernels, and the fruit peel is blown open by the fan. At this point, the square kernels may be crushed by a crusher, and the peel may be conveyed to a first crusher 1 for further separation of the peel and kernels.
