We have been designing optical sorters since 1947

Optical sorting is essential in any processing operation. It sorts grain, food and plastic, helping you meet food safety requirements and achieve a purer product quality.

Our sorting equipment uses a range of technologies including cameras, lighting and machine learning software. It removes product defects and foreign materials by color, shape and texture. 

We also have an extensive product range based on budget, capacity and the product quality you need to achieve.

Better seed germination and yields

Our optical sorters sort a wide range of seed varieties from field crops, herbage seeds to vegetable seeds. They detect unwanted colors, seed defects, diseased seeds and foreign materials – helping you achieve better germination and promote consistent seed growth.

Maximize the value of your product

Our range of optical sorters can fit anywhere in the coffee processing line – from initial handling of green coffee through to roasted beans. They remove imperfections such as color, beans damaged by insects and foreign materials, helping you to maintain a high product quality.

Meet food safety and quality standards

Our optical sorters can sort confectionery, including mints, pastilles, chocolates and gums. They remove foreign materials such as metal, stones, glass and unwanted color and product defects.

Maintain a consistent product quality

Our optical sorters sort a range of dehydrated foods such as dried onions, leeks, carrots and green beans. They detect color defects, odd lengths and unwanted stalks.

Maximize food safety

Our optical sorters sort frozen and fresh fruits including berries. They minimize product damage and remove contaminants such as sticks, plastic, cardboard and extraneous vegetable matter.

Maximize yields and product quality

Our optical sorters sort a range of grains, including oats, corn, wheat and rye. They remove unwanted colors and product defects with minimal yield loss. They can also detect foreign materials such as sticks and stones. They also offer a high level of food safety.

Achieve a better product value and yields

Our range of optical sorters are all designed to help you achieve a better quality of nuts with minimal yield loss and product damage. We use cameras and lighting to detect different defects from a variety of nuts, including peanuts, almonds, pistachios and walnuts.

Helping you reach high product quality and yields

Our optical sorters meet the most stringent requirements in food safety and quality. They remove color defects, unwanted seed varieties and foreign materials at minimal yield loss. Helping you meet food safety requirements while maintaining yields.

For consistent yields and quality

Our optical sorters are suitable for all types of pulses, including beans, lentils, grams and peas. They are designed to minimize product damage and efficiently target defects such as spots from as small as 0.5 mm in size. Helping you achieve better yields and quality.

Maximize the recovery of plastics and yields

Our range of sorters for plastics covers PET flakes, HDPE, uPVC window regrinds to WEE/ELV, ABS, PS and pellets. They can remove the same color PVC from PE or color groupings. 

Improve yields, quality and food safety

Our rice sorters sort all types of rice, including paddy, parboiled and steamed rice. They detect glass, stones and color defects, including very light and subtle color defects.

Preserve the product quality of spices

Our spice sorters remove damaged rice, foreign materials and color defects, including very light and subtle color defects. They are suitable for all types of spices, including whole or seed forms.

High product quality and yields

Our optical sorters are designed to maintain a consistent product quality and high food safety standards. They detect defects in seeds, nuts and grains. Our sorters can remove obvious to subtle color defects and foreign materials as small as 0.5 mm in size.

Improve pasta quality and yields

Our sorters for soup pasta can remove foreign materials and color defects. They include lighter pasta or stained pasta, for instance pasta stained by oil. 

High standards of tea

Our tea sorters are suitable for different varieties of tea, such as black and green flakes. They are equipped with the latest camera and lighting technologies to remove unwanted tea flakes and foreign materials at minimal loss.

Delivering safer food and higher yields

Our optical sorters sort a wide range of processed fresh and frozen vegetables. They remove large and subtle color defects, EVM such as pea pods, stalks, sticks and stems from green beans. They also remove foreign materials such as insects, stones, wood, cardboard and plastics.
