Problems solved by technology

Some professional shelling machine manufacturers directly use the separation technology of shell and kernel of sunflower seeds after shelling to the separation of shell and kernel of milk thistle seeds. The difficulty they face is that it is difficult to separate and recover about 40% of the fragmented and detritus water. Thistle shells and kernels

Abstract

The invention discloses a milk thistle seed hulling and hull and kernel separating method. The milk thistle seed hulling and hull and kernel separating method comprises the steps of removing impurities mixed in milk thistle seeds, feeding the milk thistle seeds without impurities into a hulling machine, enabling damage cracks to be gradually accumulated in the seeds through multiple short-range centrifugal throwing and achieving low-smashing-rate hulling. Hulled materials are separated into kernels, hulls and seeds containing broken matter and a little amount of kernel mixtures by a gravity sieve. The mixture portions are respectively separated into the hulls, the kernels and a seed and kernel mixture by an efficient wind power separating machine. Separated hulls and kernels are respectively used for pharmaceuticals and pharmaceutical application, the separated seed and kernel mixture is separated into seeds and kernels containing a little amount of small-grain-size seeds by a bag pit type roller classificatory, the separated seeds return to the hulling machine to be subjected to hulling treatment, the separated kernels containing the little amount of small-grain-size seeds flow back to the gravity sieve to obtain kernels again, and accordingly hulling of the milk thistle seeds and complete separation and recovery of the hulls and the kernels are achieved.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural product processing, in particular to the technical field of pretreatment of oil crop seeds, especially the technical field of oil crop seed dehulling and shell kernel separation. Background technique [0003] Milk thistle ( Silybum maruianum L. Gaertn.), Asteraceae Silybum, a dicotyledonous herbaceous plant. Milk thistle seeds belong to achenes in botany. The peel (commonly known as the shell) contains important medicinal substances silymarin and silybin. The nuts do not contain silymarin and silybin[1], and the crude fat content is about 40 %, the protein content is about 50% [2]. The efficient and full utilization of milk thistle seeds requires the shelling of milk thistle seeds and the separate recovery and utilization of shells and kernels[3-4]. [0004] For the dehulling and shell kernel separation process of milk thistle seeds, the requirements for industrial application ar...
