Following field tests during the last six months, Vincent is introducing the Twin Screws Press. Designated the Series TSP, five models are being offered.

These presses have very positive feeding characteristics, making them well suited for slippery materials. The strong pressing action of overlapping screws, plus the use of seven stages of compression, result in the best dewatering action we have ever seen in a Vincent screw press.

The Twin Screw Press is well suited to many traditional markets: citrus peel, fruit and vegetable juicing, fish waste, spent brewers' grain, shrimp shells, and alfalfa. We do not anticipate application in the pulp and paper industry, but we think that sugar beet pulp should work well.

There are three principal advantages to the Vincent design:
Automatic Control. The use of an air cylinder operated discharge cone allows the press to work well with changing feed material conditions and throughput capacities. The press has above average turn-down characteristics.

Low Horsepower. To improve dewatering, material is sliced in the press. This is a characteristic of the interrupted screw with fixed resistor teeth that can be seen in the brochure photo. The press requires less horsepower than a continuous screw press where the action is more like mashing than slicing. Also, the result of this particle size reduction is that, if the press cake goes to a dryer, better dryer performance is achieved.

OEM Gearbox. We have carefully selected major OEM gearboxes for use with our press. A choice of Sumitomo and Foote- Jones/Illinois Gear drives are available.

Overall, Vincent is delighted with the Twin Screw Press. It marks a significant advance in screw press design because the pressing performance is equal to or better than anything achieved in the past. In financial terms, it is possible to guarantee a machine with double the capacity of a single screw press, but at less cost than two single screw presses of the same diameter.
