New Hydrolyzed Feather Press This new single-screw, medium-pressure screw press is ideal for dewatering hydrolyzed feathers. It features a uniquely tapered shaft with constant diameter, variable pitch flighting. The final two pitches are equipped with hardened wear shoes that are replaceable for quick, easy maintenance. The shaft is supported at both ends with heavy-duty roller bearings, plus an additional roller thrust bearing at the feed end.
Basic wetted construction is 304 stainless steel; the inner screen is 1/8” thick with 1/16” diameter holes, the outer backup screens have 3/4” diameter holes and are 3/8” thick in the discharge section and 1/4” thick in the intermediate sections. The Hydrolyzed Feather Press also features a heavy-duty motor and a gear reducer direct coupled to the press shaft.

Dupps Pressor® high pressure screw presses are available in a wide range of sizes and configurations to meet every rendering application—from the largest, with a 13" shaft that increases throughput and improves feed capability on soft, difficult-to-press materials, to a compact and efficient 7" model ideal for smaller plants requiring only 1,500 pounds of pressed cake per hour.
Designed to produce lower fat cakes from a variety of materials, Pressors are available with horsepower ratings between 30 to 300 HP and a choice of shaft configurations. All Pressor models offer proven reliability, rugged construction and feature a single motor to drive all mechanical parts. Click here for complete specifications.
New shaft designs tailor your Pressor for optimum performance!
High volume screw presses are your best choice for high volumes of shear sensitive materials, including slurries and hydrolyzed products such as feathers and hog hair. A Dupps horizontal press features adjustable clearance between screen and shaft flighting, a pneumatic choke with a torque-limiting device for lock-up protection and a heavy-duty gearbox with a variable speed drive to compensate for material feed changes.

Dupps Tuff-Cast™ screw shaft flights can increase screw press shaft life well beyond any other flight on the market. Tuff-Cast’s unique design provides shorter break-in time, greater strength and wear resistance . . . and costs no more than ordinary flights. Dupps’ patented process for manufacturing bi-metallic hard surfaced flights casts a hard, wear-resistant surface over a softer core with a high-integrity, uniform bond. Tuff-Cast flights are virtually free of porosity and inclusions, resulting in a more durable, longer-lasting hardfacing layer. More . . .
