VINCENT PRODUCT LINE OVERVIEW

Having evolved from a builder of turn-key citrus feedmills, Vincent today has become the leading designer and manufacturer of screw presses.

We offer four Series of Screw Press designs, each with half a dozen different screw diameters. 

We also build machines which may be required for use in conjunction with screw presses.  These machines are primarily pre-thickening screens, shredders, the Fiber Filter, as well as lime dosers. 

In addition we keep available rental equipment such as pumps, tanks, agitators, and rotary drum screens.  These machines are available for pilot testing involving screw presses.

The Series VP Screw Presses were introduced in 1952.  Today they are larger, high torque machines, with relatively long screens.  They are commonly used in pulp & paper, corn wet milling, and spent coffee applications, where the press cake requires maximum dewatering.  They feature foot mounted gearboxes; screw diameters start at 16".  The Model VP-16 is popular, so several are built at a time.

The Series CP Screw Presses are also high torque machines.  They feature hollow shaft gearboxes, resulting in a compact machine.  Presses with screw sizes of 4", 6", 10", and 12" are kept in stock.  The Model CP-4, frequently used for laboratory trials, is always available.

The Series KP Presses are our most popular, probably because of relatively low cost.  They are best suited for applications like produce waste, which requires less torque than offered by the VP and CP Presses.  The KP's with screws up to 16" diameter use hollow bore gearboxes, while units larger than that use foot mounted gearboxes.  The screens are not quite as long.  Units 16" and smaller use one air cylinder instead of two to actuate the discharge cone, and they include the rotating cone feature.

The Series TSP Presses have two overlapping screws.  They are available with 6" and larger screw diameters.  They are best suited for applications involving very slippery material, those materials which require internal shredding, or installations requiring extraordinarily high throughput capacity.  Because of their cost and complexity, they are not used where a single screw press can do the job.

Vincent Shredders which mount over the inlet of screw presses are available where performance is improved by breaking up the material entering a press.

Similarly, static (sidehill or parabolic) screens are manufactured.  These are mounted over the inlet of a screw press when pre-thickening of the inbound flow is needed in order to optimize performance of the press.  Two designs are offered, with long and short screens.  They are available in widths from 18" to 72".  Wedgewire screens with various slot widths are used.

The Vincent Fiber Filter is a small footprint filter machine with strong non-blinding characteristics.  It achieves fine filtration by using filter sleeves made of woven fabric.  It was originally developed for filtering press liquor ahead of an evaporator.  In recent years its chief application has become filtration of wastewater.

Lime Dosers are used where adding hydrated lime (calcium hydroxide) causes a chemical reaction which releases water which can be separated by a screw press.  Orange peel, potato peel, and tomato waste are typical examples.

All of this equipment is available in the Vincent Rental Fleet.

Vincent started in 1931 by building a Drum Dryer.  These were discontinued in 2007.

Twin Screw Presses

 

 


The Twin Screw Press is a machine in which two screws of progressively reducing pitch rotate inside a screen surface. Material entering the hopper is subjected to gradually increasing pressure as it moves toward the exit end of the press, forcing the liquid phase to extrude through the screen. High capacity continuous dewatering is possible with slippery materials such as spent grain, fruits and vegetables, citrus waste, fish, sugar beet pulp, and shrimp waste.

Dewatering of chitin and chitosan has proven to be an excellent application because of the positive feeding characteristic of the press.

With corn silage (husk and cob) from a sweet corn cannery, the shredder (chopper) is no longer necessary.

All Twin Screw Presses require a variable speed drive (VFD), because the capacity of these presses is very sensitive to changes in speed.

Outstanding Characteristics of the Twin Screw Press include very positive feeding, low horsepower, and automatic adjustment for changes in feed rate to the press. Seven stages of compression in overlapping screws result in very strong dewatering and feeding action. A discharge cone actuated by air cylinders allows consistent performance over a wide range of flow rates and consistencies. Slicing action of the interrupted flight screws results in reduced power consumption. See US Patent 6,550,376 on our web site.

Fiber Filters

 

 

Featuring fine filtration of high gpm throughputs, the Fiber Filter is a unique machine. It operates continuously with a fabric filter that is vibrated clean by the process flow, requiring only occasional back-flush cycles.

Liquid flows with fiber contents ranging from 0.3% to 1.5% are thickened to a range of 4% to 14% solids with the Fiber Filter. The filtrate liquid is remarkably clear. The Fiber Filter can replace equipment ranging from pre-thickening screens to centrifuges. Fiber Filters can be used both to thicken flow ahead of a screw press and to remove fiber from press liquor.

COMMON APPLICATIONS

  • Cannery Wastewater
  • Canola & Soybean Protein Concentrate
  • Juice Finishing
  • Nutraceuticals
  • Pumpkin
  • Starchy Vegetable Wastewater

For more detail regarding applications see Fiber Filter II.

Mechanically the Fiber Filter has a rotating paddle impeller that whirls and pulses the incoming fluid against the inside of a cylindrical filter screen. The filter sleeve, held taught in a frame, is made of a woven polymer fabric. The fabric is available in meshes ranging from 25 microns (0.001") to 200 microns (0.008"). Fabric tension is adjusted from outside the machine, improving sanitation and facilitating operation.*

Back-flusing may be required to maintain peak throughput capacity. A wash nozzle manifold for use with water or filtrate is included with all machines, along with a booster pump and control panel.

Shredders

Frequently a screw press performs better if material is shredded before being admitted into the press. For that purpose Vincent Corporation offers a line of shredders. These are sized to bolt directly onto the inlet of Vincent screw presses.

The Vincent shredder is a horizontal machine with a 180 degree discharge area on the underside. It is ideally suited to bulky materials, such as citrus peel, whole fruit, and produce waste.

The blades rotate about a horizontal shaft. They are fixed; they do not swivel. The blades are made of hardened 410 stainless, and they are keyed to the rotor. The blades are sharpened at a 45 degree angle when slicing, as opposed to mashing, is required.

The material being shredded is forced through the discharge of the machine. The material can be thrown through a screen, a comb, or a free opening, depending on the machine configuration. The VS models have a screen mounted in the discharge, while the VCS models have a comb (or grille) in the discharge. A tooth from the comb fits between each pair of rotor blades.

The VCS models are very susceptible to serious damage if rigid tramp material, such as tools or rocks, fall into shredder. Also they are susceptible to jamming on start-up if material is left in the machine. For this reason they are commonly used without the comb in service.

A variety of screen sizes are available for those models which use screens. Typically these are in the range of 3/4" to 2", generally in the form of square-round holes. Screens are made of either 304 stainless or carbon steel.

Large shredders are typically fed with a screw conveyor. Since the shredder throws material upward as well as downward, it is important to have a cover over the screw conveyor trough at the shredder.

8" and 12" shredders are frequently used for laboratory and pilot operations. Where these machines are batch fed, a dogleg inlet chute should be used to prevent throw-back material from making a mess or causing injury.

Shredder housings can be either split or hinged, so as to allow ease of clearing jams, changing rotors, or replacing screens. In operation the upper part of the housing fits folded around the inlet chute, or it is bolted to the bottom flange of an inlet chute.

Vincent shredders are powered by premium efficiency electric motors. These are direct coupled to the rotor shaft. Some models, with two bearings, use Dodge Para-Flex couplings. Other models, with one outboard bearing, use rigid couplings.

Vincent shredders use 304 stainless for parts that are in contact with the material being shredded. Base frames are made of mild steel.

Pulp Fluidizers

SPECIAL DESIGN:   Low speed, double drum type, pulp fluidizer.

 

The Pulp Fluidizer was developed to enable pumping frozen blocks or chubs of fruit pulp while maintaining the highest level of flavor characteristics. The machine has found acceptance in fluidizing frozen pulp and pomace from both deciduous and tropical fruits. It is also used, as convenient, to liquify frozen juices in blending and not- from-concentrate operations.

The unit is a premium machine in that blocks are fluidized with a very minimum of damage to cell and fiber structure. It is a double drum type fluidizer that turns at a relatively low speed (520 rpm). These two features assure minimum disturbance to the materials being fluidized. In the machine, product is reduced to a fluid state by mechanical means. No heat is added, and, with the addition of some water (or heat from another source), the product becomes pumpable.

Specifications include:

Option: 3" Tri-Clamp sprayball connection and sprayball for CIP service.

Capacity is 30 to 40 frozen blocks of approximately 5 gallons each, per hour.

 

 

Pulp and Paper Screw Presses (older brochure)

 

 

The Vincent Screw Press is a continuous dewatering press that has proven successful in both virgin fiber and recycle mills. It has a graduated pitch, interrupted flight screw. Final pressing is controlled by a discharge cone, actuated by an air cylinder, providing easy adjustment of moisture content. Profile bar (wedgewire) screens and hardsurfaced wear areas are standard. Excellent service is obtained on screen rejects, shives, knots, and primary clarifier underflow. Inbound consistencies of 2% to 20% solids are accepted (without adjustment to the press). Press cake moisture is controllable in the range of 25% to 55% solids.

The Series VP presses use a foot mounted gearbox, while the Series CP's use a hollow-shaft gearbox. All gearboxes are rated for Class II service.

Dilute materials can be pumped directly into the screw press. Sometimes pre-thickening is required, typically with a sidehill screen.

Because the screw design, with interrupted flights, improves performance, these presses typically operate at constant speed. No variable speed drive (VFD) is required.

Laboratory and pilot plant models are popular.

Vincent maintains a very large fleet of rental presses. These are available for on-site testing and demonstration. Samples are run at our Tampa Works at no charge.

Manure Series KP Screw Presses (older brochure)

  

 

The Model KP Screw Presses are machines in which a screw of progressively reducing pitch rotates inside a cylindrical perforated screen. Material entering the hopper is subjected to gradually increasing pressure as it moves toward the exit end of the press, forcing the liquid phase to extrude through the screen. Dewatering of manure has proven successful over a wide range of applications: scrape, flush, digester, paunch; cow, hog, horse; mixed beddings. Final pressing is controlled by a discharge cone that provides easy adjustment of moisture content. The rotating cone feature eliminates purging conditions. All stainless steel construction and NEMA motors are standard. The graduated pitch and interrupted flight screw design prevents jamming, while Class II gearbox selection assures long life. Screen sleeve inserts of 3/32" and 0.033" perforation are standard; 0.015" slotted screens are optional.

Standard General Service Screw Presses (older brochure)

Twin Screw Press

The Vincent Screw Press is a continuous dewatering press, semi-custom engineered for your application. It has a graduated pitch, interrupted flight screw. The screw rotates inside a screen, forcing liquid through this screen. The Vincent Press handles materials often considered unpressable, has low operating and maintenance costs, and is easy to clean. Press cake moisture is controlled by a discharge cone, actuated by an air cylinder. This provides easy adjustment of the dewatering. Options include both perforated and profile bar (slotted) screens, a rotating cone, hard surfacing on the screw, and screen in the inlet hopper and on the face of the cone. Standard construction is stainless steel, with a carbon steel bed frame on the larger machines.

 

The Series VP presses use a foot mounted gearbox, while the Series CP's use a hollow-shaft gearbox. All gearboxes are rated for Class II service.

Dilute materials can be pumped directly into the screw press. Sometimes pre-thickening improves performance, typically with a static screen.

Because of the screw design, with interrupted flights, these presses typically operate at constant speed. No variable speed drive (VFD) is required.

Many applications for these presses involve waste dewatering. They are used on pulp & paper mill rejects, citrus peel, fiberglass insulation, cooker crumb (French fries and McNuggets), tobacco, and spent coffee grounds.

Food-grade juicing applications include pineapple, cranberries, coconut, apples, grapes, alfalfa, and many nutraceuticals.

Vapor-tight presses are a specialty. These are used in the production of SPC (soybean protein concentrate), citrus and apple pectin, Xanthan gum, and bioresin.

Laboratory and pilot plant models are popular.

Vincent maintains a very large fleet of rental presses. These are available for on-site testing and demonstration. Samples are run at our Tampa Works at no charge.
