Excessively dry seeds do not flake well therefore, a higher moisture content is required in oilseeds if they are to be formed into the thin, coherent flakes required for solvent extraction. Conditioners are usually used to add the proper amount of moisture. A conditioner can be either a vertical stacked kettle or a horizontal rotary cylinder. The units are steam jacketed and provision is made so that either steam and or water can be injected as a source of additional moisture (38). For solvent extraction, cracked soybeans are adjusted to a moisture content of 10-11% and flaked while still hot and slightly plastic that is, while at a temperature of 71-77°C (160-170°F) (36). Flaking hot minimizes fines production and also reduces power consumption (35). In the flaking rolls and transport equipment, the flakes will lose about one percentage point of moisture and enter the extractor at around 57-60°C (135-140°F).

Fig. 8.76a is a schematic cross section through an extruder with vacuum degassing. It shows first the end of the mixing/conditioning equipment (in this case an open pug mill but more commonly a closed paddle or screw mixer/ conditioner [see, for example, Fig. 8.70, Section 8.4.2]) in which the feed is prepared for extrusion. The mass is then densified in a pug sealer in which a compacted plug of material is formed that provides a dynamic seal against the vacuum that is created in the feed chamber of the extruder. While dropping into the extruder screw by gravity, gas is removed from the particulate mass. Alternatively, there is a vertical feeder/sealer (Fig. 8.76b) for smaller capacities which mounts directly to the vacuum chamber of the extruder and accomplishes a similar degassing effect.

Typically, the vertical pug mill conditioner (Fig. 6.10-21) was mounted close to the roller press and the plasticized coal/binder blend was metered into the rotating feed...
