US 5,628,280 A · Oyster cleansing/purification array

Abstract

An oyster and other molluscan cleansing system suitable for purifying, or promoting the growout of, for example, oysters, clams, mussels, or the like. The preferred embodiment of the present invention teaches a system wherein there is provided a central platform/support structure from which uniformly emanates a plurality of stacked rack-support structures, that in turn have therein generally horizontally-situated, vertically-stacked tiers of molluscan support racks. The present invention as implemented teaches a system particularly suitable for use in open water, as the structure is configured to be implemented in a variety of underwater environments, including salt, brackish, and fresh water, as desired, depending upon the species utilized therewith. In addition to flexibility from an environmental standpoint, the present system is configured to allow quality-control monitoring of the species during the cleansing or growout process, having the capability to monitor access to the system and determining the tampering thereof. The present system contemplates a ballastable, generally vertical support column, which is of adequate volume to provide variable buoyancy to the system as needed for raising or lowering the system during deployment and retrieval operations, respectively. The multi-tiered, arrayed system is configured in such a manner as to provide maximum efficiency for supporting the shellfish trays, allowing for full and free circulation of water flow to aid in the cleansing/purification, or growout process, while providing a system that is relatively compact and manageable.

An molluscan sustaining system for supporting a plurality of molluscans on trays in a clean body of water, comprising:

first and second tray rack components, each of said tray rack components each comprising a plurality of generally vertically and horizontally-aligned tray supports, each of said tray rack components having an open face, wherein there is formed open access to a tray placed upon said tray supports, said tray rack components further comprising first and second side wails, and a rear wall, said first and second side walls and rear wall configured to block the passage of trays therethrough;
a platform support structure, comprising a generally horizontally-disposed support pad having an upper side having a medial area and a support area, said platform support structure further comprising:
a generally vertically-situated support column anchored to said support pad, said support column having first and second side walls each having at least one engagement member configured to removeably engage said open face of said first and second tray rack components, respectfully, retaining said open face of said first and second tray rack components in generally closed relationship against said respective side walls of said support column.

The method of sustaining a plurality of molluscans on trays utilizing a clean body of water, comprising the steps of:

a) providing at least one tray rack component comprising a plurality of generally vertically- and horizontally-aligned tray supports, said at least one tray rack component having an open face area, wherein there is open access to a tray placed upon said tray supports, said at least one tray rack component further comprising first and second side walls, and a rear wall, said first and second side walls and rear wall configured to block the passage of trays therethrough;
b) providing a platform support structure, comprising a generally horizontally- disposed support pad having an upper side having a medial area and a support area, said platform support constructed of a relatively dense material, said platform support structure further comprising:
a generally vertically-situated support column anchored to said support pad, said support column having side wall having an engagement member configured to removeably engage said open face of said at least one tray rack component, retaining said open face of said at least one tray rack component in a generally closed relationship against said side wall of said support column;
c) placing a plurality of molluscans on a tray;
d) placing said tray with molluscans thereon through said open face area on said at least one tray rack component, onto said tray supports;
e) placing said open face area of said at least one tray rack component in a face-to-face engagement with said side wall of said support column;
f) engaging said engagement member of said side wall of said support column, removeably engaging said open face of said at least one tray rack component, retaining said open face of said at least one tray rack component in generally closed relationship against said side wall of said support column;
g) placing said platform support structure with molluscans loaded on trays therein in a clean body of water;
h) resting said support pad of said platform support structure on the bottom of said body of water;
i) allowing said platform support structure to remain in said body of water for a period of time;
j) allowing said molluscans to utilize said clean body of water;
k) removing said platform support structure from said body of water;
l) disengaging said engagement member of said side wall of said support column, disengaging said open face of said at least one tray rack component, releasing said open face of said at least one tray rack component from said side wall of said support column;
m) moving said open face area of said at least one tray rack component from face-to-face engagement with said side wall of said support column;
n) removing said tray with molluscans thereon through said open face area from said tray supports of said at least one tray rack component;
and
o) removing the molluscans from said tray.
