Abstract

The invention relates to a novel process for separating spina date seeds by using magnetic force and a magnetic separator matched with the novel process. The process comprises the following steps: gumming shells of the spina date seeds, coating iron powder and then crushing. The kernels of the crushed spina date seeds and the shells of the spina date seeds coated with the iron powder are fed into the magnetic separator of the spina date seeds, which is designed for using the novel process, and the magnetic separator of the spina date seeds can automatically and continuously separate the spina date seeds from the shells of the spina date seeds.

Description

Magnetic separating process of spina date seeds

Affiliated technical field:

The present invention relates to a kind of Chinese medicine---new technology that the sorting technology of spina date seed is complementary with it and the sorting unit that is complementary, the wild jujube kernel that especially can be after fragmentation and the mixture of nucleocapsid pick out spina date seed.(spina date seed is a kind of Chinese medicine of calming the nerves that is in great demand).

Background technology:

At present, the sorting of spina date seed all is to adopt methods such as artificial screening, selection by winnowing, flotation to roughly select, and then selects with the pure craft of manpower.Since after the jujube nucleus fragmentation its kernel and nucleocapsid granular size, shape facility, material proportion, etc. aspect the physical property all more roughly the same; So adopt methods such as screening, selection by winnowing, flotation to roughly select at last, finally still will select the spina date seed product that could form the clarity of approving on the market through the pure craft of manual work.(annotate: most jujube nucleus has only diameter 2mm to 6mm size; Kernel after the fragmentation, nucleocapsid are just littler; Will from the mixture of so little kernel, nucleocapsid, pick out kernel < annotate: its unit weight is about 1.15 tons for every cubic metre>but also be to become selecting of ton, its labour intensity is that very big, efficiency is that quality very low, product also can not be guaranteed).

In order to change the backward situation of existing main dependence hand picking spina date seed at present; Alleviate artificial labour intensity; Significantly raise labour productivity; The high-quality that guarantees product quality is stable, and the present invention provides a kind of novel technique of spina date seed sorting, and this technology and the screening installation that is complementary with it can not only reduce labor intensity and the efficiency of separation of spina date seed is improved greatly and can make the constant product quality high-quality.

The content of invention:

Plucking ripe wild jujube, the clean jujube nucleus that peeling, fleshing airing obtain later on.On the outer surface of clean jujube nucleus, dipping glue, (annotate: glue should use avirulence, glue pollution-free, that between 100 and normal temperature, can dissolve repeatedly and solidify.Like animal glue, gelatine etc.) behind the dipping glue; Slightly wait for a moment; When glue solidifies soon; Be coated with and attach iron powder (iron powder is good with 60 order to 80 orders, so not only be convenient to iron powder on the shell of jujube nucleus, be coated with attach all firmly even but also be convenient to reclaim iron powder), broken the jujube nucleus that is stained with iron powder firm on the shell then.The outer surface of the nucleocapsid in the mixture of the jujube nucleus Renhe nucleocapsid after the fragmentation has had the iron powder kernel and then has not been with iron powder; So just can be very easily with the method for magnetic separation nucleocapsid be sorted out from the mixture of kernel and nucleocapsid, remaining like this wild jujube kernel has been needed product.The core content of the invention of Take me as I am, also with good grounds this core content designs the spina date seed magnetic sorting machine of making.

Description of drawings:

According to summary of the invention and the structural principle that utilizes the spina date seed magnetic sorting machine that this invention designs shown in accompanying drawing:

1. magnetic roller (can be magneto or electromagnetic type);

2. conveyer belt (can be thin matter cotton cloth, chemical fiber fabric or thin matter plastic knitting cloth);

3. feed hopper (kernel of the jujube nucleus of input after the fragmentation and the mixture of nucleocapsid);

4. conveyer belt idler roller;

5. the outlet of wild jujube kernel (product);

6. the outlet of wild jujube nucleocapsid (nonmagnetic substance making).

Embodiment:

Embodiment below in conjunction with description of drawings the utility model.According to impregnation, be coated with and attach the broken then new technology of iron powder and be ready to treat after the material of sorting.Send into ready material at the charging aperture of separator; Be the kernel and the compound that has the nucleocapsid that adheres to iron powder of the jujube nucleus after the fragmentation; Such mixed material on conveyer belt to the magnetic roller direction motion (the magnetic roller is the inhour rotation) of < numbering 1 >; When mixed material moved near magnetic roller top, the wild jujube nucleocapsid that the magnetic force of magnetic roller will be stained with iron powder adsorbed, and the wild jujube kernel is not then adsorbed by the magnetic roller because of there being iron powder.When Far Left that mixed material moves to magnetic roller in the Figure of description is promptly near " A " some position; The spina date seed that is not adsorbed vertically falls under the effect of gravity; Get into the outlet of the wild jujube kernel of < numbering 5>in the Figure of description; And the wild jujube nucleocapsid that is stained with iron powder that is adsorbed moves with conveyer belt and the magnetic roller of < numbering 2 >, when pass through the magnetic roller shown in the Figure of description bottom the time, the wild jujube nucleocapsid that at this moment is adsorbed is transferred band and has been pulled away from the magnetic roller gradually; In the time of near " B " some position when the distance that is pulled away from reaches a certain size in Figure of description; The wild jujube nucleocapsid falls into the outlet of wild jujube nucleocapsid of < numbering 6>of Figure of description with breaking away from conveyer belt under the effect of gravity, the wild jujube kernel is exported from the different outlets of spina date seed magnetic sorting machine with nucleocapsid; The exit collects with different containers, has so just realized the mechanization sorting to the mixture of wild jujube kernel and nucleocapsid.Owing to be to work continuously and the rotating speed adjustable of magnetic roller, the quality of its product and output can obtain the assurance of the best.

The invention has the beneficial effects as follows:

Can make the work of letter sorting spina date seed realize mechanization, solved in the real spina date seed production because " bottleneck " problem of the whole process of production that hand picking forms, and the automatic and mechanical of the production formation overall process of impelling whole spina date seed of having ready conditions.And its production equipment is simple in structure, durable in use, and maintenance cost is few, and these two auxiliary material of glue in its technical process and iron powder are recyclable, makes its sorting cost be significantly less than the artificial separation cost.

Claims

1. the method that can use magnetic field force to carry out the spina date seed sorting, this method is: earlier at the outer surface impregnation of jujube nucleus and adhere to iron powder, and then broken jujube nucleus, the outer surface of the nucleocapsid after the fragmentation is stained with iron powder; Re-use the wild jujube nucleocapsid that magnet or magnetic sorting machine will be stained with iron powder and pick out, thereby obtain spina date seed as product.
