Stainless Steel Sinking Grates
These stainless steel grates are used to keep must/cap submerged during active fermentation. CO2 easily escapes through the perforations. The grates can often reduce the number of punch-downs needed as they prevent the cap from drying out between pump-overs and punch-downs.
Once punch-down is complete and the grapes are softened, the grate is lowered onto the cap, pushed down until submerged and kept in place by inflating the pneumatic gasket using a simple hand pump.
Inflatable (pneumatic) gaskets (8/160) and pumps are available from HD Process Ltd for $89.35 and $68.25 respectively, excluding GST. The grates are raised and lowered using a chainblock attached to a stainless steel strop. The strop prices can vary depending on required length and are available from Chain and Rigging Ltd.
Dimensions: 1605mm diameter x 90mm high x 3mm perforation.
Price: $495+GST each.
