Embodiment Construction

[0040] Various embodiments of methods and systems for cooling (eg, blast freezing) items, such as perishable food, that have previously been packaged as groups of items onto shipping and storage pallets are described below. The systems and techniques discussed herein provide a simple and easily scalable blast chamber that prevents short circulation of air flow through items in the blast chamber. Each blower chamber may contain a plurality of suction channels providing independent fluid paths for directing air drawn from different rows in the blower chamber into the fans.

[0041] refer to figure 1 , the example plenum system 100 is configured to cool items loaded therein. Although the plenum system 100 is primarily described herein as a freezer, it should be understood that the plenum system 100 can be used with or without modification as a cooler. The blast chamber system 100 may include one or more blast chambers 102, each configured to receive items and operative to cool...

Abstract

The present invention provides a blast chamber system (100) having a simple and scalable design that prevents short circulation of air flow through any tray (92) in the blast chamber (102). The blast chamber (102) includes a plurality of suction channels (141) that provide independent fluid paths to direct air drawn from different rows (114) in the blast chamber (102) into a fan (130).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application 16 / 745,232, filed January 16, 2020, which is a continuation of U.S. Patent Application 16 / 453,834, filed June 26, 2019 , both of which are incorporated herein by reference in their entirety. technical field [0003] This specification relates to techniques for efficiently cooling physical items in a plenum. Background technique [0004] Convective air blast freezing is the process of facilitating the freezing of items such as food by mechanically passing very cold air over them. This air blast freezing is often used for very large quantities carried on pallets. Thousands of cubic feet per minute (CFM) of air flow are available for freezing. Forced air freezing is often used on perishable foodstuffs (eg, fruit and meat) geographically near the point of origin of the food processing. Such goods may then be stored in refrigerated warehouses for short or long...
