Undulating shaker screen assembly

An undulating shaker screen assembly, comprising:

• a support frame that defines a frame opening, said support frame having a top frame surface and a bottom frame surface opposing said top frame surface;
• and
• an undulating screen subassembly attached to said support frame, said undulating screen subassembly, including:
• a planar panel having an upper panel surface, a lower panel surface opposing said upper panel surface, a panel peripheral sidewall connecting said upper panel surface and said lower panel surface together, and a plurality of panel perforations extending through said upper panel surface and said lower panel surface;
• and
• a mesh section attached to said planar panel and including at least one mesh layer, said mesh section having a top mesh section surface, a bottom mesh section surface opposing said top mesh section surface, a mesh section peripheral edge connecting said top mesh section surface and said bottom mesh section surface together, and a plurality of mesh section openings extending through said top mesh section surface and said bottom mesh section surface, wherein:
• said mesh section peripheral edge includes a first side and an opposing second side;
• said mesh section includes a series of elongated undulations extending from said first side of said mesh section peripheral edge to said second side of said mesh section peripheral edge, each of said elongated undulations including a planar base portion, a raised portion, a first undulation side and a second undulation side, wherein each of said undulation sides extends upwardly from said planar base portion, and wherein:
• said planar base portion includes a first end, a second end, and a planar base portion length, wherein said planar base portion length is at least 0.125 inch;
• said first undulation side extends upwardly from said planar base portion at a first angle with respect to said planar base portion and includes a bottom end attached to said first end of said planar base portion, a top end attached to a raised portion, and a first undulation side length, wherein said first undulation side length is at least 0.25 inch;
• and
• said second undulation side extends upwardly from said planar base portion at a second angle with respect to said planar base portion and includes a bottom end attached to said second end of said planar base portion, a top end attached to a raised portion, and a second undulation side length, wherein said second undulation side length is at least 0.5 inch, wherein said first angle and second angle are different such that said first angle is less than said second angle;
• wherein the ratio of said planar base portion length to the longer of said first undulation side length and said second undulation side length is in the range of from 1:4 to 5:3;
• and
• wherein said mesh section is attached to said planar panel such that said mesh section openings are positioned over said panel perforations and said planar base portions of said undulations are attached to said upper panel surface.
