## 4 Technological Line for Separating Seeds and Pressing Oil  
To solve the technological problem, this paper outlines an idea of the technological line allowing the separation of apple seeds from the dried mass of apple pomace on an industrial scale and obtaining edible oil from apple seeds by cold pressing [32]. Cold-pressed oils contain health-promoting substances, such as tocopherols, polyphenol compounds, and carotenoids, which have strong antioxidant properties and help protect against the activity of free radicals in the human body [24; 34]. Therefore, these oils have found recognition in the functional food market [34; 35].  
The essence of the proposed technological line for obtaining apple seed oil is the use of two sections for separating seeds from dried apple pomace (Figure 1). The first separation section (A) contains a drum-sieve separator (1), rotary beaters (3), a dried pomace dosing unit (2), and containers for small fractions such as fragments of skins, seed cores, and tails (4). At the outlet, the drum-sieve separator (1) couples with a blower section (B, 5) equipped with a fan (6), an outlet for light waste fractions (6\({}^{\prime}\)), and a cyclone filter collecting light fractions (7). The section is paired with a tank of pre-cleaned seeds (8). The tank (8) is a dispenser for the second separation section (C), equipped with a linear vibrating screen (9), sieve belt conveyors moved on rollers with two mesh diameters, larger and smaller than the size of the seeds (10, 11), and outlets for the separated two fractions of waste (12). At the output, the linear vibrating screener couples with a blower section (D, 13) that includes a fan (14), an outlet for light waste fractions (14\({}^{\prime}\)), and a cyclone filter (15). The section connects to the separated seed tank (16) through a connection node. This tank (16) is also a dispenser for the pressing section (E) equipped with a screw press (17), in which the cold oil pressing process is carried out. The press couples with a container for the expeller (18) and a container for raw oil (19). The container is connected to the filtration section (F) equipped with a filter press or other oil filtration system (20), which is then connected to the bottling section (G) equipped with an oil filler for bottles (21). The description of the line is illustrative, and its performance depends on the scale of the components used.
