Peralatan industri 2
Seringkali dalam industri pengolahan hasil
pertanian diperlukan operasi pemisahan
komponen-komponen suatu campuran
menjadi fraksi-fraksinya. Fraksi-fraksi dari
suatu campuran dapat berbeda satu
dengan yang lainnya dalam ukuran partikel,
fasa atau komposisi kimia.
Peralatan industri 3
Teknik untuk pemisahan komponen-komponen
suatu campuran dapat dibagi menjadi :
1. Metode pemisahan mekanis, yang biasanya berguna
untuk pemisahan partikel padat atau bahan cair tetes :
2. Operasi-operasi difusinal, yang melibatkan perubahan
fasa atau pemindahan bahan dari suatu fasa ke fasa
lainnya.

As material is gravity-fed into the unit, rotating helical paddles continuously propel the material against the cylindrical screen, and accelerate them through the apertures. On-size material then drops through the first of two discharge spouts, into a storage vessel or processing equipment. The paddles, which do not contact the screen, also serve to break-up agglomerated materials. Oversized particles unable to pass through the apertures, exit through the end of the screen cylinder and fall through a second discharge spout for discarding or re-processing. Cylindrical screens are offered in woven nylon, monofilament, stainless steel, and stainless steel wedge wire, to accommodate a wide range of materials. Available to industrial, food, dairy and pharmaceutical standards including 3-A and BISSC.

60 to 80% Higher capacity than single stage screeners, at low cost
Two Stage High Capacity Screener
Peralatan industri 21
A new VIBROSCREEN® "Two-Stage RC" circular vibratory screener offers 60 to 80 percent higher capacities than conventional screeners of equal diameter. The two-stage design features an upper screen deck having a 360° annular gap at the screen's periphery. This deck is fed with more material than it can efficiently screen, with two results: 1) On-size material falling through the upper screen is funneled
through a hole in the center of the lower screen to the machine's discharge outlet and
2) The overflow of on-size material plus all oversize material cascade over the screen's periphery onto a second screen of equal mesh that scalps the balance of material in normal fashion. The machine boosts capacity without increasing floor space, and costs 20 to 30 percent less than conventional screeners having larger diameters and equivalent capacities. The two-stage screening hardware can be installed new or retrofit in diameters from 40 to 100" (1015 to 2540mm) to scalp up to 70 tons per hour. Available to 3-A, FDA, BISSC and other sanitary standards, the units can be disassembled rapidly for thorough wash down.

ULTRA-HIGH CAPACITY IN-LINE PNEUMATIC SCREENER ALLOWS RAPID CLEANING, SCREEN CHANGES
Peralatan industri 23
PRINCIPLE OF OPERATIONThe chambers above the top screen and below the bottom screen are connected by a central bypass chute, causing on-size material and air entering the central chamber to reach the bottom outlet via two pathways: upward through the top screen then downward through the chute; or downward hrough the bottom screen. Oversize material is ejected through a spout at the periphery of the lower screen. A tangential inlet along the horizontal centerline of the central chamber prevents material from impacting screens at 90° angles,minimizing screen damage and the breakdown of oversize foreign material into on-size contaminants.

Peralatan industri 32
he Simplicity four-bearing gyrating screen is the original
mechanically vibrated screen using a counter-balanced
eccentric shaft. The shaft is accurately machined to
provide an exact counter-balance for the weight of the
entire frame and deck structure, "building in" positive
action with perfect smoothness. Simplicity four-bearing
screens can be mounted by supporting the main frame
from below, or suspending it by rods or cables attached
to plant superstructure. With either type of mounting,
positive action of the screen's counter-balanced shaft will
maintain full effectiveness and minimize transfer of
vibration to the supporting structure.

Centrifugal ScreenersPRINCIPLE OF OPERATION
Material is fed by gravity or pneumatically into the feed inlet and redirected into the cylindrical sifting chamber by means of a feed screw. Rotating, helical paddles within the chamber continuously propel the material against the screen, while the resultant, centrifugal force on the particles accelerates them through the apertures. These rotating paddles, which never make contact with the screen, also serve to breakup soft agglomerates. Over-sized particles and trash are ejected via the oversize discharge spout. Sift, scalp, de-dust, de-lump and
de-water virtually any bulk solid or slurry

The Rotary Drum Filter
DescriptionThe Rotary Vacuum Drum Filter belongs to the bottom feed group and is one of the oldest filters applied to the chemical process industry.
Peralatan industri 57
The valve has three bridge blocks:
1. Vacuum and blow zones separating bridge: This bridge cuts off the vacuum so it is slightly wider than the internal pipe port. 2. Dead zone bridge: This bridge opens to vacuum once a compartment submerges. 3. Start-up assist bridge: At start-up the upper vacuum zone is open to atmosphere and a cake may be formed only when closing the valve that controls this zone.
Operational Sequence
Peralatan industri 59
In broad terms drum filters are suitable to the following process requirements:
Slurries with solids that do not tend to settle rapidly and will remain in a uniform suspension under gentle agitation.
Cakes which do not require long drying times to reach asymptotic moisture values.
Cakes when a single washing stage is sufficient to remove residual contaminants from the cake or yield maximum recovery of filtrate.
Filtrates that generally do not require a sharp separation between the mother and wash filtrates. Some complex valves, however, enable atmospheric purging of the sectors and internal piping to facilitate a sharp separation of filtrates.
Filtrates that are acceptable with a low quantity of fines that pass trough the filter cloth in the first few seconds of cake formation. Broadly, and depending on particle size and cloth permeability, the filtrate may contain 1000 to 5000 ppm insolubles.
