Method and device for preparing cheese by ohmic heat treatment
View Patent ↗An invention directed to a process and device for electrically heating and preparing pasta filata type cheeses. The ohmic heating process of this invention is introduced after separation of initial curd from whey, as heated stretching is initiated to create nascent pasta filata cheese fibers. An apparatus is devised to receive the newly formed curd mass and to provide contact of the mass with an electric coupler that channels electric current through the conductive cheese mass as it is concurrently stretched. The features of this device include an electrically charged element, a grounding element and a texturizing tool.
1. A device for preparing pasta filata cheese by ohmic heating comprising
a chamber for receiving, containing and heating nascent pasta filata cheese mass,
said chamber having a first open end for receiving said nascent pasta filata cheese mass and a second open end for releasing said pasta filata cheese mass,
one or more grounded electro-conductive heating element positionable within or proximate to said chamber,
each said grounded electro-conductive heating element of said one or more grounded electro-conductive heating element comprising any of each following electro-conductive plate, screw auger, probe, or combinations thereof,
wherein the device further comprising a counter rotating dual compression belt system for forming pasta filata cheese from heated past filata curd,
said counter rotating dual compression belt system comprising a first and second circular belt strap, each said circular belt strap having a flat surface,
said flat surface of said first circular belt strap oppositely facing said flat surface of said second circular belt strap,
said first and second circular belt strap each rotatable in counter-rotational direction of each other wherein heated pasta filata cheese curd is receivable, pullable and stretchable therethrough in compressed manner,
each said grounded electro-conductive heating element of said one or more grounded electro-conductive heating element comprising non-corrosive, non-flaking and non-precipitous material,
each said grounded electro-conducive heating element of said one or more grounded electro-conductive heating element directly contactable with said pasta filata cheese curd for direct conduction of electrical heat throughout said pasta filata cheese curd,
one or more thermocouple positionable at one or more locations within or proximate to said chamber and directly contactable with said pasta filata cheese curd for remote transmission of cheese curd temperature,
the electrical output of said one or more grounded electro-conductive heating element is remotely controllable by a remote controller in communication with said one or more thermocouple wherein the temperature of said pasta filata cheese curd is remotely registerable and said one or more electro-conductive heating element is remotely adjustable,
said pasta filata cheese curd is receivable by said chamber, is heatable by electro-conduction by direct contact with said one or more grounded electro-conductive heating element while being stretched and pulled therethrough and is releasable from said counter-rotating dual compression belt system as a nascent pasta filata cheese mass.
2. Said device for preparing pasta filata cheese by ohmic heating of claim 1 wherein said pasta filata cheese curd is heatable to a temperature between 120 Fahrenheit and 165 Fahrenheit by direct contact of said pasta filata cheese curd with said one or more grounded electro-conductive heating element.
3. Said device for preparing pasta filata cheese by ohmic heating of claim 1 wherein said grounded electro-conductive heating element comprising three-phase power in series or parallel form.
