System for processing primary food product waste into secondary food product

摘要

A system for producing secondary food product from primary food product waste is disclosed that comprises several modular subsections: a staging subsystem, a processing subsystem, a drying subsystem, and a pelletization subsystem. Each subsystem, and the connections between subsystems, are sealed such that the food product being processed is isolated from the general environment. Product is dried by the dryer in such a way that it emerges from the dryer at a desired moisture content level and at ambient temperature. A moisture sensor may provide control data to a controller that in turn controls product throughput to obtain a desired moisture content level. High nutritional content and long lifespan of the processed product can be maintained, while reducing the weight of the final product. One or more of the subsystems may be portable and configured for convenient connection and disconnection to mating subsystems, and to facilitate permitting for portable operation.

1. A system for producing a secondary food product from a primary food product waste, comprising:
a primary food product waste staging subsystem; a primary food product waste processing subsystem, said processing subsystem comprising;
a pre-processing subsystem, coupled to said staging subsystem in a sealed fashion, for receipt of primary food product waste therefrom, configured for removal of inorganic material from the primary food product waste;a mill subsystem, coupled to said pre-processing subsystem in a sealed fashion, for receipt of primary food product waste therefrom, configured to mill the primary food product waste to a selected constituent size;a press subsystem, coupled to said mill subsystem in a sealed fashion, configured to separate the milled or shredded primary food product liquid constituents, foreign solid constituents and residue, and target material constituents;a transfer subsystem for transferring said separated liquid constituents, foreign solid constituents and residue, and target material constituents to respective storage containers in a sealed fashion; a dryer subsystem comprising:
a first screw auger transfer and working element having an auger heating element disposed therein and substantially along the length thereof;a housing having an input port and an output port, said housing enclosing said first screw auger transfer and working element, said housing configured to provide and sustain a vacuum therein such that said screw auger transfer and working element may transfer and work product within said housing under a vacuum pressure;a heating element extending substantially the length of said screw auger transfer and working element, disposed and configured to impart thermal energy to said housing and in turn to product being transferred and worked with said housing;a motor coupled to said screw auger transfer and working element for rotating said screw auger transfer and working element;a controller, coupled to said motor, for controlling the speed of said motor, and for ultimately controlling rotational speed of said screw auger transfer and working elements, wherein rotation speed of said motor is controlled to complete production of secondary food product from said primary food product waste by obtaining secondary food product from said screw auger transfer and working elements having a desired moisture content; and a delivery subsystem for receiving said secondary food product having a desired moisture content from said screw auger transfer and working element in a sealed fashion, and retaining said product for further processing or distribution.
