Abstract
A preselected volume of a liquified cooking medium is supplied to a continuous-flow system serving a cooking chamber. In the course of heating the supplied cooking medium prior to the cooking cycle, an overflow device is operative to remove that volume of the thus expanded cooking medium in excess of the preselected volume. On commencement of the cooking cycle, the overflow device is rendered inoperative.
Claims13
A system for use in cooking food parts comprising:
- (a) a source containing cooking liquid;
- (b) a cooking chamber having an inlet, an outlet and an overflow port for issuing from said chamber cooking liquid in volume exceeding a preselected volume;
- (c) first conduit means connected between said chamber inlet and outlet and including means for pumping cooking liquid and first valve means having a first state providing flow of cooking liquid from said source to said chamber and settable to alternate second state for recirculating cooking liquid from said chamber outlet to said chamber inlet;
- (d) second conduit means including second valve means connected between said overflow port and said source, said second valve means having a first state providing flow of said cooking liquid therethrough and settable to alternate second state for discontinuing flow of cooking liquid therethrough, and sensor means operated upon flow of cooking liquid through said second valve means;
- and
- (e) control means for setting said first valve means in said second state thereof upon operation of said sensor means and including switch means connected to said second valve means for setting said second valve means in said second state thereof.

A system for use in cooking food parts comprising:
- (a) a source containing cooking liquid;
- (b) cooking chamber means for containing food parts and providing output indication on commencement of a cooking operation;
- (c) first means connected between said source and said chamber means and operable in first state for supplying cooking liquid from said source to said chamber means and in alternate second state for recirculating through said chamber means cooking liquid supplied thereto;
- (d) second means connected between said source and said chamber means and operable in first state for removing from said chamber means cooking liquid supplied thereto in volume exceeding a preselected volume and in alternate second state for discontinuing such removal of cooking liquid from said chamber means;
- (e) liquid flow sensor means for providing output indication of liquid flow through said second means;
- and
- (f) control means for operating said first and second means jointly in said first states thereof, and responsive to said output indication of said liquid flow sensor means for then operating said first means in said second state upon supply of cooking liquid to said chamber means in volume exceeding said preselected volume while continuing operation of said second means in said first state and for then operating said first and second means jointly in said second states upon said output indication by said chamber means.
