Differential pressing roller type peony seed unshelling and cleaning device

Abstract

The invention relates to the technical field of processing machinery of agricultural products and discloses a differential pressing roller type peony seed unshelling and cleaning device. The differential pressing roller type peony seed unshelling and cleaning device comprises an enclosure, wherein a feeding hopper is arranged above the enclosure; the enclosure is internally provided with a shell crushing system, a separation system and a winnowing system; the shell crushing system comprises two pressing rollers of which the roller surfaces have different linear speeds; the separation system comprises a rotary drum, a plurality of scraping plates which are arranged on the circumference of the rotary drum and are arranged along the axial direction of the rotary drum, and an impacting baffle which is arranged on an inner wall of the enclosure and is used for blocking materials and thrashing seeds and shells; the winnowing system comprises a packing auger which is arranged at one side below the rotary drum and a draught fan arranged at the other side below the rotary drum; the packing auger is parallel to the rotary drum; a discharging hole is formed in a part, located at a conveying terminal of the packing auger, on the enclosure; the direction of an air outlet of the draught fan is set to be inclined upwards and tangent to the upper part of the packing auger; an impurity discharging hole is formed in a position, opposite to the air outlet of the draught fan, on the enclosure. According to the differential pressing roller type peony seed unshelling and cleaning device, the peony seeds and shells are completely separated through a two-step method and a plurality of times of winnowing.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing machinery, in particular to a differential pressure roller type peony seed shelling and cleaning device. Background technique [0002] Peony flowers are gorgeous in color, fragrant with jade smiles, elegant and magnificent, known as the "king of flowers". They are not only ornamental, but also can be made into peony tea, peony cakes and other delicacies for people to enjoy. The crystallization of the essence of peony plants not only inherits all the characteristics of peony itself, but also has its own unique medicinal and nutritional components. Heze, the origin of peony, has successively cooperated with Beijing Forestry University, Peking University, Chinese Academy of Sciences and other famous universities and research institutes. , launched the world's first batch of peony seed oil in 2009, and obtained the provincial achievement appraisal of Shandong Province.

AI Technical Summary

Problems solved by technology

Because the shell of peony seeds is very hard, it is difficult to remove the shell. At present, there are few equipment specially used for shelling and cleaning peony seeds in the market. The two processes of shelling and post-cleaning can be pressed to make oil, which increases labor costs and affects output efficiency

The shelling equipment in the prior art adopts the impact type, so that the peony seeds gain a certain amount of kinetic energy and then impact on a hard object. The impact force is difficult to adjust. If the force is too small, it is not easy to remove the shells. damage, easy to deteriorate, affecting degreasing quality
