SPECTRUM Vacuum De-stoners are used for separating heavier impurities such as stones, glass, metal etc., from food grains and seeds such as wheat, corn, peas, paddy, sesame, coffee, peanuts etc. as well as any other dry granular material.

How it works ?

The principle used is the stratification of the product into heavier and lighter fractions by forcing air through the bed of material. This is achieved by means of a Suction fan connected to the machine or by connecting the machine to a Central Aspiration System.

The vibration of the deck is achieved by means of unbalanced vibratory motors mounted below the product discharge end of the machine. The Vibrating deck pushes the heavier material in contact with the deck upwards towards the stone discharge spout. The lighter good material flows down the inclined, vibrating deck and exits through the clean product spout.

The inclination of the vibrating deck and the stroke of eccentric motion can be finely adjusted to achieve the optimum degree of separation. The de-stoning efficiency is extremely high with consistent and trouble free performance.

SPECTRUM Pressure De-stoners are used for separating heavier impurities such as stones, glass, metal etc., from food grains and seeds such as Lentils, Legumes, Coffee, Peanuts etc. and other dry granular material.

How it works ?

The principle used is the stratification of the product into heavier and lighter fractions by forcing air through the bed of material. This is achieved by means of pressure fans located in the body of the machine, below the vibrating deck. The vibrating deck pushes the heavier material in contact with the deck upwards towards the stone discharge spout. The lighter material flows down the inclined, vibrating deck and exits through the clean product spout.

The inclination of the vibrating deck, speed of eccentric motion, feed rate and the air flow can be individually adjusted to achieve the optimum degree of separation. A wide variety of deck screens are available to suit specific applications.

All adjustments can be made with ease and minimum of operator training.

Features

• Can be connected to a Central Aspiration System.
• Provided with clean product and stone discharge spouts.
• Hood with windows provided for on-line product viewing.

Gravity Separators are used to separate products of the same size but with a difference in specific weight. They can be used effectively to remove partially eaten, immature and broken seeds to ensure maximum quality of the final product. They may be used to separate and standardize coffee, peanuts, corn, peas, rice, wheat, sesame, and other food grains.

How it works ?

These Gravity Separators have a rectangular deck so that the product travels a longer distance resulting in cleaner separation of light and heavy particles and the lowest percentage of middlings.

The product flows over the vibrating deck in which pressurized air is forced through causing the material to stratify according to its specific weight. The heavier particles travel to the higher level and the lighter particles travel to the lower level of the deck.

In order to obtain efficient separation by specific weight, the pressurized air supply needs to be accurately adjusted and this is accomplished by having individually adjustable air fans to control the volume of air distribution at different areas of the vibrating deck. The table inclination, speed of eccentric motion and the feed rate can be precisely adjusted with ease and minimum of operator training.

Features

• Can easily separate granular materials according to the weight of the product.
• Easy deck removal for cleaning.
• Multi-fan system for accurate control of air.
• Precise Control of air, feed rate and speed of deck motion.
• Easy adjustment of deck inclination in both longitudinal and transverse directions.

SPECTRUM Cross Beater type Coffee Hullers are extremely efficient in hulling both parchment and dry cherry coffee. Reduced friction between beans prevents generation of dust and results in minimum loss of good product due to breakage of the beans.

How it works ?

Coffee is fed through the hulling cylinder and forced through the perforated screen by the cross beaters. A powerful Aspirator then separates the husk and peels from the coffee beans.

An Oscillating screen, adjusted by a stepless adjustable drive separates hulled and unhulled coffee. In the oscillating screen, unhulled coffee moves towards the center of the screen and is collected through a duct whereas the hulled coffee beans move towards the outer rim of the screen and is discharged through an outlet duct.

Swing down doors allow quick and easy access to the hulling cylinders for cleaning or replacement of blades and perforated screen.
