Patent number: 10098375Abstract: Method for pasteurizing almonds and other nuts with steam at atmospheric pressure. The amount of condensation on and the consequent water uptake of nuts is limited by pasteurizing the nuts in a heating chamber with a gaseous atmosphere including a steam mixture and forming a forced-convection path through the nuts. The limited water uptake maintains the quality of the nuts. A forced-convection steam cooker conveying food products on a foraminous conveyor belt forces the steam mixture through the nuts. A preheater preheats the nuts so that they can be pasteurized in the steam cooker at a temperature of between 85° C. and 99° C. to reduce the dwell time and increase throughput.Type: GrantFiled: January 10, 2017Date of Patent: October 16, 2018Assignee: Laitram, L.L.C.Inventors: Joseph F.

Patent number: 6012384Abstract: A mobile container adapted for transporting perishable goods includes a front wall, a rear wall, a pair of side walls extending therebetween so as to define an elongated enclosure having a longitudinal axis and adapted to receive a cargo load. An air recirculation plenum is defined in the enclosure adjacent to the front wall. A refrigeration system is in fluid communication with the air recirculation plenum and is adapted to induct air at a first temperature and to exhaust air at a second temperature. A pair of air delivery plenums extend from the bulkhead along the length of the enclosure parallel to the longitudinal axis. Each of the pair of air delivery plenums is defined by a corresponding one of the pair of side walls and a plenum wall disposed spaced from the corresponding side wall and extending from the upper margins of the enclosure such that the plenum wall is adapted to be co-extensive and in abutting contact with a portion of the cargo load.Type: GrantFiled: April 30, 1999Date of Patent: January 11, 2000Assignee: Trans Tech Holdings GroupInventors: Mark A. Badalament, Daniel S. Harmsen

Patent number: 5965185Abstract: A transportable and size-adjustable ripening apparatus for controlled ripening of produce includes a chamber defined by a ceiling, a floor, and walls connecting the ceiling and the floor. The chamber is configured to receive a row of boxed produce that defines an interstitial volume with one of the walls to create a low-pressure plenum. The ripening apparatus also includes an air flow control system for transferring air between a high pressure plenum and the low pressure plenum, and which controls the temperature of the transferred air. The plena are generally enclosed to inhibit airflow therebetween except for airflow through the air control system and through openings in the produce boxes. The air control system includes one system for controlling the flow of air through a refrigeration unit, and another system for circulating air without refrigeration. The invention is preferably constructed from an existing ISO (International Standards Organization) container.Type: GrantFiled: July 2, 1997Date of Patent: October 12, 1999Assignee: Cool Care, Ltd.Inventor: Michael Bianco

Patent number: 5958274Abstract: Apparatus to transfer heat to the surface of a product includes a product support, a duct having a duct entrance, a duct outlet and a longitudinal duct axis and a plenum for delivering temperature controlled fluid into the entrance of the duct such that fluid flows longitudinally of the duct toward the outlet. A perforated plate has at least one orifice, having an orifice axis extending generally toward a product support for forming a jet of fluid, having a jet axis, flowing in a predetermined direction. The longitudinal duct axis of the duct is rotated relative to the orifice axis for changing the direction of the jet axis relative to the orifice axis for moving the jet axis relative to the product support.Type: GrantFiled: March 5, 1997Date of Patent: September 28, 1999Inventors: Michael J. Dobie, Carl J. Dougherty, John R. Norris

Patent number: 5826496Abstract: The invention relates to a cooking oven for cooking food products. A modular cooking oven herein disclosed may include a plurality of modules arranged in end-to-end relationship, with partitions between adjacent modules. A continuously moving conveyor belt extends longitudinally through the oven from an inlet end to an outlet end. Hot cooking gas is continuously circulated in a closed path which is generally perpendicular to the longitudinal axis of the oven. A hot gas is circulated downwardly and then is directed through a plurality of axially spaced transversed slots, both above and below the conveyor, toward the conveyor belt and food cooking thereon. Spent gasses are then deflected away from the conveyor belt into a recirculation path, and are reheated in this return path prior to recirculation in a further cycle. Air and steam inlets are provided at various points, and are so arranged that an operator can provide either similar or different conditions of temperature and humidity in different modules.Type: GrantFiled: July 23, 1996Date of Patent: October 27, 1998Assignee: Stein, Inc.Inventor: Bruce C. Jara

Patent number: 5818014Abstract: A combination microwave and air impingement oven has two magnetrons and an air handling system that includes two or more reciprocating ducts through which air is dispensed into the oven. The rotating ducts are configured to stir microwave energy in the oven to prevent formation of hot spots and to sweep microwave radiation over the surface of the food product. A foraminous partition, configured to encircle a portion of the cooking chamber, has a central portion and extremities mounted to divide the interior of the cabinet into a cooking chamber and an air heating chamber. The partition extends around a major part of the periphery of the cooking chamber such that air is drawn along multiple paths toward side walls and toward the rear wall from the cooking chamber.Type: GrantFiled: June 5, 1995Date of Patent: October 6, 1998Assignee: Patentsmith Technology, Ltd.Inventors: Donald P. Smith, deceased, Michael J. Dobie, Alden B. Sparman, Sr., John R. Norris, Neal S. Cooper, Carl J. Dougherty
