Abstract:
A conveyor belt for transporting a product, includes a plurality of transport assemblies, each one of the plurality of transport assemblies comprising a side link assembly; a support assembly connected to the side link assembly; a product support member supported on the support assembly and adapted for displaceable movement with respect to the side link assembly and the support assembly; and an actuation member supporting the product support member with respect to the side link assembly and the support assembly, the actuation member coacting with the side link assembly for moving the product support member between a first position wherein the product support member is in a first plane of travel with respect to the side link assembly for conveying the product, and a second position wherein the product support member transitions to a second plane of travel with respect to the side link assembly different from the first plane of travel for providing a space between the product support member of each one of the plurality of transport assemblies.

Abstract:
A product support surface for a conveyor belt includes a pair of side links spaced apart by a rod connected therebetween; and a longitudinal member attached to the rod between the pair of side links, the longitudinal member having a surface to support a product thereon during a conveying mode and to be pivoted with respect to the pair of side links during a cleaning mode.
Abstract:
A heat exchanger and related method for a thermoacoustic refrigeration system are provided, which includes a warm end of the heat exchanger, a cryogen passing through the warm end to remove heat generated by a thermoacoustic wave generator, and a cool end through which a cooling medium passes to be cooled by the heat transfer at the warm end, wherein cryogenic gas is exhausted from the warm end, and a cooling gas is exhausted from the cool end at a lower temperature than a temperature of the warm end.
Abstract:
An apparatus and method for processing products by chilling or freezing includes a conveyor for conveying the products along a plane of travel; lifting means disposed for intermittent contact with the conveyor during processing; cam means rotatable for contacting and displacing the lifting means to contact and displace the conveyor from the plane of travel, thereby displacing the products on the conveyor to prevent the products from adhering to the conveyor and other of the products; and drive means operatively associated with the cam means to impart rotational movement to the cam means for intermittently contacting and displacing the lifting means.

Abstract:
A refrigeration system includes a cooler or freezer enclosure; a heat exchanger within the enclosure; a bulk storage tank in fluid communication with the heat exchanger; a sound generator in fluid communication with the heat exchanger; a thermoacoustic refrigerator in acoustic communication with the sound generator; and an indirect heat exchange loop in heat transfer contact with the thermoacoustic refrigerator. The heat exchanger is adapted to receive pressurized fluid from the bulk storage tank, and to provide pressurized gas to the sound generator.
Abstract:
An apparatus and method for providing treatment by impingement to a continuous supply of food product includes a treatment zone at an ambient pressure, a fluid delivery zone at an elevated pressure, and a circulation assembly. Impingement plates containing apertures separate the zones. When treatment fluid is drawn through the impingement apertures, jets of treatment fluid are produced and impinge upon food product traveling through the treatment zone. The apparatus can employ a conveyor mechanism to accommodate food product from a continuous supply, as opposed to batches.
Abstract:
An apparatus for the chilling or freezing of items, particularly food items includes an entrance module, an exit module and may include one or more intermediate modules. Each module includes a portion of a belt for conveying items and a motor driven impeller for circulating a stream of cryogenic gas around the items. The velocity of the stream of cryogenic gas is increased through the use of one or more impingers creating impingement jets above and below the belt. The impinger may be a plate having a series of holes or it may be a series of channels. The impinger effects the rate of heat transfer from the cryogen to the items. A sprayer for spraying liquid cryogen into the impingement jets provides an immediate freezing of the surface of an item. A pneumatically actuated ball valve is used to vibrate the impingers to remove snow and ice on the impingers.
Abstract:
A freezer for a product includes a housing having a space therein, and an inlet and an outlet in communication with the space; a conveyor having a first side for conveying the product through the space, and a second side opposite to the first side; an agitating apparatus disposed proximate the conveyor for contacting the conveyor at select intervals to agitate the conveyor and displace the product at the first side; a first longitudinal member disposed proximate the first side of the conveyor and having at least one hole extending therethrough; and at least one circulation device disposed in the space proximate the longitudinal member for directing a cryogenic substance through the at least one hole onto the product.
