control unit disposed in the housing;

a control panel on the housing and in electronic communication with the control unit; and

at least one rotatable roller in the cradle section of the housing, and

an electric motor operatively connected to the rollers for causing rotation thereof;

said canister comprising a substantially cylindrical main body which is substantially translucent, and a cover comprising a valve, a handle for operating said valve, and a gear plate disposed between said handle and said valve,

said cover being sealably attachable to said main body,

wherein said valve comprises:

a valve body comprising a cylindrical sleeve with a hollow passageway formed therethrough, and a branch pine extending substantially transversely from a central portion of the sleeve;

a substantially cylindrical valve ball dimensioned to fit inside the passageway of the sleeve, said valve ball having a cylindrical bore formed centrally therethrough,

a pair of bushings disposed in said sleeve of said valve body, each of said bushings having a respective inwardly-facing concave sealing surface formed therein, and

a valve stem extending between and interconnecting said valve ball and said gear plate;

wherein pivotal movement of said handle causes corresponding pivotal movement of said valve ball to selectively open or block fluid flow through said valve.

12. The food treatment apparatus of claim 11 , wherein said housing comprises a storage section formed therein, and a hinged cover over said storage section.

13. The food treatment apparatus of claim 11 , wherein the cradle section of the housing has at least one arcuate cutout formed therein to allow a user to insert a hand below a portion of said canister as it rests on said cradle section.

14. The food treatment apparatus of claim 11 , wherein the main canister body has a plurality of grooves formed in a side thereof, said grooves being alignable with the rollers of said base unit.

15. The food treatment apparatus of claim 11 , further comprising a vacuum line with a built-in fluid trap for interconnecting said base unit to said canister, wherein said vacuum line comprises a connection fitting for inserting into an opening in said canister valve, wherein said connection fitting has at least two O-ring seals thereon.

16. The food treatment apparatus of claim 1 , wherein said base unit comprises four rollers, at least one of which is driven by said motor.

17. A food treatment apparatus, comprising a base unit and a canister for rotatable placement on the base unit;
