1. A dry food dispensing device for controlling the flow of dry food when dispensed, said device comprising: a storage receptacle for containing dry food, wherein said receptacle is seated over a base providing a housing for a dispensing mechanism, said dispensing mechanism comprising;a turnable free flow valve having wings, said valve wings normally level and blocking free flow of said stored dry food from said storage receptacle, said valve being rotatable to a valve opening angle allowing free flow of said stored dry food, means for limiting said valve rotation to a predetermined position of said wings at said valve opening angle offset from said normal position; and a depressible handle for controlling said free flow valve angle rotation via said limiting means comprising a fixed handle position stop enclosing a rotatable handle position stop, wherein said fixed handle position stop comprises a first ring having an internal truncated rim forming an inner edge, and said rotatable handle position stop comprises a second ring rotatable within said first ring and having a circumferential shoulder of a predetermined length, such that when said shoulder hits said inner edge during rotation, a fixed valve opening angle is determined at said predetermined position,wherein when said handle is depressed and said valve is rotated to said predetermined position at said valve opening angle, said dispensing mechanism releases a portion of said stored dry food, said portion being determined by a user as a function of time said turnable free flow valve is held at said valve opening angle. 2. The dispensing device of claim 1 wherein said storage receptacle is removably seated over said base. 3. The dispensing device of claim 1 wherein said second ring is interchangeable within said first ring to enable adjustment of said valve opening angle as desired. 4. The dispensing device of claim 1 wherein an increase in said circumferential shoulder length over said predetermined length causes a corresponding decrease in said second ring rotation, thereby decreasing said fixed valve opening angle. 5. The dispensing device of claim 1 wherein a decrease in said circumferential shoulder length over said predetermined length causes a corresponding increase in said second ring rotation, thereby increasing said fixed valve opening angle. 6. The dispensing device of claim 1 wherein said means for limiting comprises a spring acting to restore said turnable free flow valve to said normal position once said depressible handle is released from said valve opening angle at said predetermined position. 7. The dispensing device of claim 1 wherein said turnable free flow valve comprises a pair of wings extending on either side of a rotatable shaft for blocking free flow of said stored dry food from said storage receptacle by sealing against inner walls of said storage receptacle, wherein said turnable free flow valve further comprises a third wing extending at an angle from said shaft and below an individual one of said pair of wings, having a length extending beyond said individual wing, to seal against said inner walls and prevent leakage of said stored dry food. 8. The dispensing device of claim 1 wherein said stored dry food may be provided in fine or coarse granular form, flakes or chunky-type food pieces, including toppings, powders and the like. 9. The dispensing device of claim 1 wherein said wings are formed of flexible material which minimizes mechanical interference with said stored dry food so as not to alter its shape or consistency. 10. A method of dispensing dry food by controlling the flow thereof, said method comprising: providing a storage receptacle for containing dry food, wherein said receptacle is seated over a base providing a housing for a dispensing mechanism, said dispensing mechanism comprising; a turnable free flow valve having wings, said valve wings normally level and blocking free flow of said stored dry food from said storage receptacle, said valve being rotatable to a valve opening angle allowing free flow of said stored dry food, and means for limiting said valve rotation to a predetermined position of said wings at said valve opening angle offset from said normal position; and a depressible handle for controlling said free flow valve angle rotation via said limiting means, and depressing said handle so as to rotate said valve to said predetermined position at said valve opening angle, wherein said predetermined position and said valve opening angle are adjustable as desired, wherein said adjustment is provided by said dispensing mechanism comprising a fixed handle position stop enclosing a rotatable handle position stop, wherein said fixed handle position stop comprises a first ring having an internal truncated rim forming an inner edge, and said rotatable handle position stop comprises a second ring rotatable within said first ring and having a circumferential shoulder of a predetermined length, such that when said shoulder hits said inner edge during rotation, a fixed valve opening angle is determined at said predetermined position, such that said dispensing mechanism releases a portion of said stored dry food, said portion being determined by a user as a function of time said turnable free flow valve is held at said valve opening angle. 11. The method of claim 10 wherein said adjustment is provided by interchanging said second ring within said first ring to change said valve opening angle. 12. The method of claim 10 wherein said valve opening angle determines a dispensing rate of said stored dry food flow. 13. The method of claim 12 wherein an increased valve opening angle establishes an increased stored dry food flow dispensing rate. 14. The method of claim 13 wherein a quantity of said stored dry food may be obtained by adjusting at least one of said dispensing rate and said time said turnable free flow valve is held at said valve opening angle. 15. The method of claim 10 wherein said dispensing mechanism is adapted for use by a pet depressing said handle. 16. The method of claim 10 wherein said dispensing mechanism is adapted for use by an automatic system depressing said handle.
