Abstract: A dough depositing machine adapted for use in the manufacture of non-traditional baked goods and methods related thereto. Non-traditional dough (e.g., gluten-free, wheat-free, dairy-free, egg-free, vegetarian, or vegan dough) may have properties that are more difficult to accommodate during manufacturing than the properties of traditional dough. Accordingly, various components of the dough depositing machine may be adapted to operate with non-traditional dough. For example, at least one of a dough delivery mechanism, a forming portion, a cutting assembly and a controller of the dough depositing machine may be adapted for use with non-traditional dough. These components of a dough depositing mechanism may be provided as originally manufactured equipment or may be retrofit to an existing dough depositing machine designed for use with traditional dough.

Abstract: Powdered starting material utilized for molding (e.g., rotational molding, injection molding, blow molding), extrusion, and the like can be preheated to reduce the time required to complete the processing of the material. After being preheated to a temperature below a melting temperature of the powder, the powder is transferred to a processing station.

After obtaining a desired distribution of the material over the walls of the mold, the temperature of the mold is decreased as rotation of the mold continues. When the article is sufficiently cooled, the article is removed from the mold.

Abstract: Concrete elements, such as blocks or bricks, are molded or cast by forming in a primary mold cavity a secondary mold made of a portion of a thermoplastic film which has been contacted with a flat heater surface to assure a uniformly heated film portion which is then sucked into the primary mold cavity without wrinkles and filled with concrete mix. The secondary mold with the concrete mix in it is withdrawn, for example, sucked out of the primary mold cavity well before any effective hardening of the concrete mix, so that curing and hardening takes place in the secondary mold outside the primary mold cavity. This early withdrawing is important because it avoids expansion of the curing mix in the primary mold, whereby removal from the primary mold is facilitated. Additionally, the early removal with the aid of the secondary mold assures a more efficient use of the primary molds which are used again while the hardening is still going on in the secondary mold.

The system utilizes only enough molding pressure to assure distribution of the plastic to all parts of the mold cavity and shaping of the molded product to the geometric design of the mold. The system includes a transfer means for the molds which returns the emptied molds for recycling through the molding process.
