Abstract

The invention relates to the cotton-cleaning industry, more specifically, to a method for delintering cotton seeds, in particular chemical seed exposure, mainly aerosol. The purpose of the invention is to increase productivity by imparting the necessary corrosion protection to the details without increasing the moisture content of the seeds above acceptable standards. For this, it is necessary, after applying an aerosol of 32% hydrochloric acid to the lowered seeds in the chemical reactor, to bring the seeds into an auxiliary device, give them a time delay, and then treat them with a 20% potassium alkali composition. When an alkaline aerosol is combined with a residual hydrochloric acid content of 2.5-2.6%, potassium chloride is released during the reaction, which does not have a high corrosive effect on metal parts, and water. The method includes the following operations: chemical treatment of HCL, holding, transporting, mixing, neutralizing KOH, drying the seeds with a stream of hot air and sucking exhaust air followed by feeding to the operation of mechanical fiber separation. Seeding after hydrochloric acid aerosol is 120-125 seconds. Neutralization of seeds is carried out for 2-3 seconds, drying time of seeds depending on relative humidity of air 165-175 seconds at a temperature of thermal agent 50-65 ° C, 2 hp f-crystals, 1 tab., 2 ill.

Description

Seed aging after hydrochloric acid aerosol has been applied to pubescent seeds is carried out with a seed transplant from the reactor in an additional device with a time interval of 120-125 seconds. During this time, the attachment of the delint is weakened.

to the seed.

i Neutralization of seeds from the residual content of hydrochloric acid is carried out after they are carried out in the same transport device with an alkali of KOH, following the chemical reaction;

HC1. + KOH KCl +

and

20

After neutralization, the seeds are dried and mixed in the device at the same time. Drying is carried out by exposure to hot air for 160-165 seconds.

The process of mixing seeds is carried out in the device during their transportation with a change in the step of entry of the auger feathers by flexible vane working bodies,

Exhaust air is extracted at the end of the process by a suction system by means of a pneumatic duct, a fan and purifiers.

Fig, 1 shows the scheme of technology. the process; in fig. 2 is a section A-A in FIG. 1,

The pubescent seeds after exposure to hydrochloric acid 35 from the reactor; 1 along an inclined tray 2 comes into the device - a vinistast auger 3; Seeds after aging, neutralization, drying and mixing - through tray 4 go into the lower, parallel distribution auger 5, from where it goes to the loading of this filling machines 6,

Neutralization is carried out by aerosol spraying with 20% KOH alkaline at the rate of 40 liters per 1 ton of seeds at point C. The presence of residual hydrochloric acid before neutralization in the mass of continuously transporting seeds is 2.6 - 3%, and after - 0.05 - 0.1%, the neutralization time of seeds is 2-3 s.

After neutralization, the CD section is mixed simultaneously and the seeds are dried with a stream of hot air at a critical temperature of 55 - 60 ° C, the seed drying time is 165 s, exhaust air is sucked from the inclined shaft and DE section. To obtain comparative data, the residual hydrochloric acid content of the descended seeds is determined when their ampoules are transported. the reactor through the transport auger before entering the seeds into the seed raspberry NAD. Residual content of hydrochloric acid on seeds is 3%. The data are tabulated.

The content of the KS1 salt on the pubescent seeds after the reaction does not adversely affect the corrosion resistance of the components and parts of the machines. At the same time, the potassium chloride seed sown seed is a component of the fertilizer when sown.

As can be seen from the table, the exhaust air treatment is carried out at high relative humidity by means of an air outlet 7,

They do not cause a significant increase in the humidity of the seeds and bring them to acceptable standards.

When using the proposed method, it is possible to

fan 8 and is injected into cyclones 9 and 10 for double cleaning.

Seed mixing is carried out using vinyl blades 11 (Fig 2).

At the ends of the blades, the rubber-50 is fixed to the trimming of the pubescent seeds from the base pads of 12. test content of the salt salt.
