The invention provides methods and devices for heating or cooling viscous materials such as meat emulsions useful for producing food and other products. The devices include a heat exchanger comprising a first plate, a second plate attached to the first plate, and a first spacer and a second spacer arranged between the first plate and the second plate. The first plate, the second plate, the first spacer, and the second spacer define at least one temperature controlled passage for a product to pass through the heat exchanger.

A method for processing or manufacturing a meat product is disclosed. Frozen meat is provided into a meat grinder having a grinder plate having a first surface and a second surface defining apertures of different sizes and shapes extending between the first surface and the second surface. The meat is urged through the apertures by a coolant and chopped or broken into frozen pieces by a blade rotating a spaced distance from the second surface of the plate. The frozen pieces are then provided into and conveyed by an auger conveyor as more coolant is provided into the conveyor to further cool the meat pieces. The meat pieces are then sifted to more optimally obtain desired pieces sizes or range of sizes and/or sublimate the coolant.

A fire searing process for meat comprises cooking meat in an oven and then at least crust-freezing the meat in a freezer. The oven has a temperature of at least 1500° F., and the meat is cooked in the oven for approximately 10 seconds to 3 minutes. The meat is cooked to a depth of approximately 0.25 to 25% of the meat extending into an inner surface of the meat from an outer surface of the meat to form a crust-like portion proximate the outer surface of the meat. The meat is then at least crust-frozen in a freezer having a temperature of approximately −35 to 0° F. for approximately 1 to 6 minutes. The freezer prevents the meat from being further cooked to preserve the crust-like portion proximate the outer surface of the meat.

A delivery apparatus and method for delivering liquid cryogen to a chilling application includes a liquid cryogen feed tank; a liquid cryogen conduit in fluid communication between the feed tank and the chilling application; a weight measurement device for controlling the weight of liquid cryogen to be delivered to the chilling application through the conduit; a flow controller for controlling the speed of delivery of the liquid cryogen to the chilling application; wherein the chilling application uses the liquid cryogen to produce an exhaust gas; a device for measuring the temperature of the exhaust gas, the device in operative communication with the flow controller; wherein the flow controller is configured to vary the speed of delivery of liquid cryogen in response to the temperature of the exhaust gas.

A temperature controlled storage apparatus 8(10), comprising; a plurality of lockable storage spaces, each of the plurality of lockable storage spaces comprising one or more compartments; in which the temperature of each of the one or more compartments is independently controllable to provide either one of: chilled temperature; or frozen temperature; and wherein access to the storage space is remotely programmable.

A method for extending the use of water during the production of products for human consumption in food production facilities for an extended period of time of at least two production days and up to seven production days by delivering an initial chemical charge at the beginning of each production day to return the process water to the desired antimicrobial solution concentration to provide acceptable antimicrobial control of the process water over the extended period of time. The method providing acceptable antimicrobial control in the processing of any protein or non-protein based food products that require batch or continuous chilling as part of the production process. The length of time that the water may be used in a processing tank may be dramatically and safely increased before the processing tank is emptied for cleaning, sanitizing and refilling.
