DISC PULPERS: Disc Pulpers are used in wet processing plants to pulp ripe coffee fruit to parchment. The coffee is fed from large fruit tanks and the wet parchment is discharged into fermentation and washing tanks. The fruit skin is discharged into a pit for water recovery and recirculation.

The pulping operation takes place between the rubbing action of the bulbs on the disc and the lateral pulping bars called chop rails. The gap between the surface of the bulb and the chop rail can be adjusted to allow for any clearance that may be required according to the variety and size of coffee fruit processed. The hopper is fitted with a feed mechanism which ensures even feeding of the fruit to the disc surface.

AAGAARD SYSTEM: Aagaard Wet Processing System has been designed to produce a uniform quality of First Parchment and for total pulping of the intake fruits. The system consists of the following equipments:

Rotary Cherry Feeder to ensure even feeding of the cherry to the various disc surfaces for pulping. Cherry Feeders consist of a device to intake fruit from the fruit tank, a device to destone the fruit and to evenly spread the fruits. This feeding system is not dependent on water and hence less water is needed in the pulping process. 

A Primary Disc Pulper can be Two, Three or Four Disc type depending on the capacities required. These Pulpers are fitted with small type hoppers. The flexible Chop Rail option ensures that a wider range of fruit sizes is pulped with reduced nip damage. Sixteen nylon fingers, backed by a flat piece of rubber with a tension adjusting screw, ensure this flexibility.

A regulating door ensures that the feed can be varied from 800 kgs. to 4000 kgs. per hour.

COFFEE PRECLEANERS:  Coffee Precleaners are designed to clean and screen coffee, prior to feeding on to the next processing stage. The machine effectively removes iron particles, stones, sand, rubble, leaves, twigs and other unwanted matter. Separation is achieved by a series of screens, the first screen removing large impurities and the bottom screen removing fine materials such as sand and dust. The middle screen separates the coffee and delivers it clean. To increase the efficiency of cleaning, an Air Sifter is used after the precleaning

The machine requires minimum maintenance and has individual rubber ball cleaning mechanisms to ensure that the screens have maximum screening area at all times. The screen inclination, throw angle and amplitude can be varied, depending on the input product for ideal results. Vibratory motion of the screen is effected by means of two low power vibratory motors.

SMOUT PEELER POLISHER: Smout Peeler Polishers are specially designed for treatment of dry parchment coffee. When fitted with phosphor bronze cone and liners, they provide a fine polish and color to the coffee. The machines can be used for peeling and polishing or for only polishing to remove the silver skin. Since the Smout performs both peeling and polishing operations simultaneously, there is no necessity for passing the parchment through a huller prior to polishing. This saves considerable energy and also from damage to the coffee.

DRY DESTONERS: Dry Destoners are used for removing stones from green coffee, dry parchment or dry cherry. The Destoner is designed to take advantage of the difference in specific weights between the stones and the coffee. The incoming coffee is fed into an inclined sifting frame fitted with a special screen, which is exposed to a controllable air exhaust. The lighter fraction, consisting of good coffee, forms a fluid layer above the sieve and flows over to the outlet while the heavier stones contacting the screens move upslope by the frame vibration. The sieve frame is vibrated through the use of a vibratory motor.

                                                                The machine has an input feed regulation device and an aspiration throat for connection to a central aspiration line or to an individual aspiration line with fan, cyclone, airlocks and piping. The vacuum above the sieve can be adjusted by a butterfly control valve and read on a water gauge tube. Depending upon the input material characteristics, the feed, aspiration intensity, screen inclination, throw angle setting and vibration amplitude can be adjusted for optimum results.

MINI DRY PROCESSING PLANT: Mini Dry Processing Plant has been designed to cater to small processors who process up to 2000kgs. of green coffee output per day. It is capable of cleaning, hulling and grading dry cherry, dry parchment or green coffee. The plant is mounted on steel frame and can be made into a mobile unit. Catadors are used after Hullers and Smout Peeler Polishers to remove husk and light coffee. They are also used after grading for secondary catadoring of light beans and triage.

The coffee is fed into an air current where separation is carried out by density differences and the light matter is carried up and exited via the lights outlet. The heavy beans fall on a wire screen and exit through the front of the machine. The machine is equipped with an electric motor platform and a shaft extension to suit Electric motor drive or can be supplied to suit a Diesel Engine drive.
