     The invention relates to a fat and oil industry, in particular to methods of extraction from sunflower seed.
    The purpose of the invention is to simplify the process.
    The invention provides a method for the extraction of the solid-liquid system B from lipids and polyphenols from rolled sunflower seed, which includes the use of a solvent mixture consisting of a hydrocarbon solvent, ethanol and water as an extraction solvent.
    The method is carried out as follows.
    The solid-liquid extraction process involves the supply of a fresh solvent or solvent mixture to one of the extraction vessels connected in series.
    each of these vessels contains a solid material and is provided with a hole for the solvent inlet, solvent outlet, mixing means and filtering element to prevent solid material with a particle size exceeding a certain level from escaping through the solvent outlet, and the filtering element is located in the vessel near from the mixing devices, as a result of which the mixing of the solvent or mixture of solvents with the help of mixing means reduces the clogging of the filtering lementa solid material passing solvent of increased extracted substances from this extraction vessel sequentially through the other extraction vessels. After extraction has taken place

    substances from the solid material in this nominal extraction vessel; stop the supply of fresh solvent or solvent mixture to the next extraction vessel in the flow direction; the solid material is removed from the specified extraction vessel and a new batch of fresh solid material is loaded into it; -, - the cancer vessel is connected in series with the extraction vessel located at the bottom of the flow. Such a process makes it possible to extract several components with a solvent or a mixture of two or more solvents in a whole series of successively installed vessels, and the liquid content of these vessels is maintained in a mixed state during the entire extraction cycle.
    The solvent (or solvents) is directed (or removed) into several vessels with a flow rate (unitary), which is chosen in a certain interval - within 2-15 m / h / / m, and the flow through successive vessels moves continuously.
    After each vessel is loaded with a suitably crushed solid material, each vessel is filled with a solvent and stirring begins.
    Then a fresh solvent is fed to the first vessel, as a result of which the solvent already contained in it is diluted and the extraction process becomes very effective.
    The solvent is then removed from the first vessel and sent to the next extraction vessel, in which the described process is repeated, and then the process is repeated sequentially in all of the extraction vessels.
    As you measure, the solid material, i.e. extracting the extractable substances contained in the first extraction vessel, it is discharged and a fresh solvent is introduced into the vessel, and this vessel is mixed to the last place in the sequential row of vessels. From the first extraction vessel, the fresh solvent is started to flow into the next vessel, etc.

    (the finest fractions) transition. In the solvent flow, in addition to a number of sequentially installed extraction vessels, you must use a filter that allows you to separate the solid material captured by the solvent flow from the liquid phase and complete the extraction treatment.
    The main parameter is the specific (unitary) value of the flow rate of the solvent, which is directed to and removed from each extraction vessel (it must be in the interval 2-15).
    Other parameters, in particular, the ratio between the height and diameter of the vessel, the geometric characteristics of the filter element, the size of the holes of the filter element, the material from which the filter element is made, the thickness of the filter element, the kinematic viscosity of the suspension, and the intensity of mixing which is maintained in the vessel.
    At the end of the simultaneous extraction of more than one undesirable component from sunflower seed, a mixture can be used which includes three solvents distributed in different phases.
    The use of such a mixture makes it possible to achieve a high yield of the product during the extraction process, if it is used in the course of the said extraction procedure.
    The method of extracting a solid with a liquid is carried out in a temperature range of 20-50 ° C for a period of time from 30 minutes to 6 hours, and the ratio between the weight of the flattened seed and the volume of the solvent mixture is in the range of 1: 1-1: 10 (i.e. from 1 kg to 1 l to 1 kg to 10 l).
    Analytical methods for determining the chemical characteristics of sunflower seed and products derived from it
    The moisture content, ash content and the amount of Crude Fiber were determined according to standard procedures.
    The protein content was expressed in terms of the Kjeldahl micro-nitrogen content, multiplied by
    5.70. The total lipid content was determined in accordance with the method of determination with petroleum ether. Determination of polyphenolic compounds was carried out according to Bittoni’s colorimetric method. The total content of sugars was determined according to the method of M. Dubois et al. Modified in that the implementation of the individual sucrose was omitted during its implementation and only the total sugar content that was present in the product was taken into account.
    The protein dispersion index (AIR), used to determine the amount of nitrogen that can be dispersed in water at natural pH, is consistent with the method described by OOHA.
    Example 1. Sunflower seed, whose composition is given in Table 1, is subjected to full peeling in a hydromechanical peeling machine and the obtained peeled c, which is further subjected to flattening to a thickness of 0.25 mm in the Diefenbach mill 12/30/30, thus obtained the product is treated with a mixture of the following composition, vol,% n hexane 60; ethanol 35; water 5.
