Fiber Filter
|
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. 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. * US Patent 6,117,321

Manure Series KP Screw Presses
|
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.

Pulp Fluidizer
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:
- Basic T-304 stainless steel construction.
- All gaskets of food grade material.
- Contact teeth are made of specially hardened T-410 stainless steel.
- Guard door, product hood, and feed tray are #3 finish.
- Clean-out door and flanged discharge port.
- Housing is glass bead and 2-B finish.
- 7-1/2 hp TEFC chemical duty motor.
- Hardened teeth sprockets.
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
|
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. 0.5-1

Series KP Screw Presses
|
The Series KP Screw Press is a machine 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 fibrous materials has proven successful over a wide range of applications. Waste from produce, canneries, plastic recyclers, breweries, poultry processors, and even some paper mill applications, will dewater with excellent results. Pressing is controlled by a discharge cone that provides easy adjustment of moisture content. 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. The rotating cone feature eliminates purging conditions. Screen sleeve inserts of 3/32" and 0.033" perforation are standard; 0.015" slotted screens are optional.

Shredder
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.

Standard General Service Screw Presses
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.

Twin Screw Press
|
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.
