Abstract

With a method as well as a system for processing of sunflower extraction grist, particularly for obtaining proteins, wherein the particles from shell kernel parts and adhering proteins of the extraction grist are separated from one another by means of screening, a solution is to be created for processing the extraction grist of sunflowers, which occurs in the production of sunflower oil, in such a manner that it can be utilized in many different ways and, in particular, in practical manner.

This is achieved, in terms of method, by means of the following steps:

comminuting the grist by means of breaking it in beater impact mills (3) and/or corrugated rollers (16), screening the mixture of coarse and fine particles produced, separating the plant shells (fibers) and proteins by using water (5, 18), drying (6) the components, and pressing (8) the woody components into pellets as fuel for energy production.

Claims

1. Method for processing of sunflower extraction grist, particularly for obtaining proteins, wherein the particles from shell kernel parts and adhering proteins of the extraction grist are separated from one another by means of screening,

comprising the following method steps:

comminuting the grist by means of breaking it in beater impact mills and/or corrugated rollers, screening the mixture of coarse and fine particles produced, separating the plant shells (fibers) and proteins by using water, drying the components, and pressing the woody components into pellets as fuel for energy production.

2. Method according to claim 1, comprising

at least two comminution steps in a beater impact mill and/or corrugated roller, with subsequent screening, before the water separation.

3. Method according to claim 1, using a beater impact mill,

wherein

the mixture, in each instance, is subjected to an impact period of 5 to 30 seconds.

4. Method according to claim 1,

wherein

separation of the plant shells (fibers) and proteins is undertaken by means of introduction into a water separator or the like, and removal of the floating parts and the parts that settle.

5. Method according to claim 1,

wherein

after at least one comminution step and screening step, the remaining coarse components are sprinkled, and, after a dwell period that serves for swelling of the proteins, the proteins are separated from the woody components by means of squeeze-screening and/or squeeze-rolling.

6. Method according to claim 1,

comprising

a drying step of the fraction of plant parts and proteins produced.

7. Method according to claim 1,

comprising

a separation step by means of air separators

8. System for implementation of the method according to claim 1,

comprising

at least two impact mills (3) and/or corrugated roller grinding units (16), a water separation system (5), such as a water separator, drying devices, silos (2, 10) for the extraction grist and the products obtained, as well as corresponding conveying devices between the system elements.

9. System according to claim 8,

comprising

a device (8) for the production of pellets.

10. System according to claim 8,

wherein

the water separation system is formed by a conveyor belt (17) having a sprinkling device (18), as well as a subsequent squeezing device (19, 21).
