The invention relates to the automatic control of the production of vegetable oils and can be used in the construction of effective management systems for preparatory branches of oil extraction plants.

The aim of the invention is to increase productivity and improve the quality of processed products.

The drawing shows a diagram of the device that implements the proposed method.

The method of automatic control of the process of collapsing-separation

when processing sunflower seeds, they measure: - The specific surface of the rushanka and the core, compare the measured values with the set values and adjust, depending on the result of the comparison, the size of the gap between the drum and the seed bar, respectively, and the angle of inclination of the seed blinds. In addition, the proposed method provides for the stabilization of the seed consumption for processing, and the specified seed flow rate is adjusted depending on the measured values of the specific surface of the Ruschanka and the core. Moreover, with

Specific surface of the Ruskin SMJ, and

consequently, it is necessary to increase the gap U between the drum and the seed of the seed, and, conversely, a decrease in Sng requires a decrease in o.

An increase in the muzziness of the core leads to an increase in its specific surface area of the Sun, and, consequently, to a decrease in the angle of inclination of the lamellar louvre, and, conversely, a decrease in SMQ requires an increase in N. If, despite the change in about, 5cd becomes less than a predetermined value, then increase the flow of seeds of Gc to the seed, and if Sun becomes greater than 5, | T, then Cc should be reduced.

Similarly, if, despite the change in pC, the Sun becomes smaller

The device contains a seed germ 1, a seed flow sensor 2, a seed supply adjustment device 3 for a complex wake, a rushanka rapid analysis system 4, a device for adjusting the gap between the drum and the hatch deck, a seed analysis system 6, a core analysis system 7 , a device 8 for adjusting the angle of inclination of the eye louvre and the logic unit 9.

The seeds are fed to the seed of 1 through the device 3 regulating the supply and the seed flow sensor. The signal on the current flow rate of the seeds from the sensor 2 is fed to the feed control device 3, where it is compared with the target flow value. If the values do not match, a control signal is generated to the actuator that controls the change in the seed supply (a gate in the path of the seed flow). Feed change occurs until

The signal about the current value of the specific surface of the rushanka from the system 4 is fed to the device 5 for controlling the size of the gap between the drum and the seed deck, where it is compared with the specified value of the specific surface. When the values mismatch, a control signal is generated to the actuator to change the gap between the drum and the deck deck.

The signal about the current value of the specific surface of the core from the system 7 is fed to the device 8 for adjusting the angle of inclination of the seed louvre, where it is compared with the specified value of the specific surface. When there is a mismatch of values, a control signal is generated to the actuator 8 for adjusting the angle of inclination of the louvre.

In parallel, signals about the current values of the specific surface of the rushanka and the core from the systems 4 and 7 of the express analysis are sent to logic block 9, where they are compared with the specified limit values of the specific surface of the rushanka and the core. When the current values exceed the specified limits, the logic unit 9 generates a signal for a change (correction) of the specified value of the seed flow for the complex of the small stream - wake. This signal from block 9 is fed to a feed control device (flow rate) 3, which changes the seed feed to the complex.

The use of the proposed method of automatic control of the breaking-separation process during the processing of sunflower seeds allows to increase the productivity of the complex rushka-wake and the quality of the processed products.
