Daniel Ghadiri, ProexFood LLC:
“Our new peelers use very little water”
ProexFood LLC is developing complete solutions, from the arrival of fruit and vegetables at a processing plant all the way to final packaging. The lines are available for many different products, including potatoes, carrots, onions, sweet corn, mushrooms, berries, apples and many more. The company is constantly working on improving their solutions to make them even more efficient, says Daniel Ghadiri, the CTO of ProexFood.
ProexFood offers clients different machines for processing fresh foods, IQF-products, vacuum packaged produce and canned foods. “We are active globally – from Australia to the west coast of the United States. Everything is from the one hand with us – if we can’t build or develop the machines ourselves, we rely on our trusted partners.
The company has three different technologies for peeling: a knife peeler, u-bed peeler/scrubber, and a rotary cage waterless peeler. Ghadiri explains how the Knife Peeler works: “This machine is ideal to peel potatoes and other root crops, such as beets or turnips. In a processing line, the peeler is located after pre-washing and de-stoning the products. A rotating drum with built-in knife modules represents the working unit.” A product is tipped into the loading chute using a step conveyor belt. From there it falls into the drum cavity where it is advanced by means of the worm-shaft. “The speed of the peeling process is controlled by the rotation of this shaft. The continuous rotation of the drum causes the rotation of the product against the set of knives. On contact with sharp knife-edges the surface of the product peels-off.” Peeled vegetables are fed-out using an outlet chute, while the peels are collected underneath the drum either in a container or removed by means of a distinct conveyor belt.
The u-bed peeler / scrubber and rotary cage waterless peeler use abrasive shafts or brushes to remove the outer layer of the product. The units are suited to peel and/or scrub a wide variety of products as well. “Peeling with abrasive materials and brushes leaves a much more smooth finish than the knife peeler. Scrubbing vegetables is made easy with the units: potatoes and beets after steam, tomatoes with pre-treatment or corn for chips and tortillas. The peeler improves yields by brushing the peel away instead of cutting. After the process there is also a lower cooked starch carry-over in rinse water.” The benefits of the rotary cage waterless peeler include: lower moisture and higher solids content and significantly reduced water usage and further treatment costs. “In addition, all ProEx peelers are built to require minimal maintenance with easily accessible parts.” The brushes can be exchanged quickly and easily, explains the expert.
“Peelers and scrubbers sold by ProEx provide finished products the processors are proud to sell,” says Ghadiri. “The product finish is either natural looking by the knife peeler or smooth and finished as provided by the u-bed and rotary cage waterless peeler.” He names some more benefits of the system: “The all-stainless steel construction throughout ensures long life. Cleanout doors are positioned to allow easy access for maintenance, quick change of the rolls for easy maintenance and minimal downtime. Continuous welds eliminate cracks and crevices and make easy sanitation possible.”
