Sunflower Seed Decorticating Machine

Sunflower seeds are a major source of protein for human consumption and are used in a variety of food products.sunflower seed decorticating machine They also serve as a source of oil for many commercial applications, including food, pharmaceuticals, and cosmetics. Sunflower seed hulls can be used to produce biodiesel, which is an alternative fuel that reduces pollution and greenhouse gas emissions. In addition, sunflower hulls can be used as an organic fertilizer.

Traditionally, both confectionery and oilseed sunflower are mechanically decorticated (separating a mixture of hulls and seed meats into two fractions) and hulled (separating the hulls from the seed meats).sunflower seed decorticating machine These processes typically use equipment that uses either percussion or friction. Both processes are capital intensive and can damage the seed meats. Moreover, they tend to produce a large percentage of broken or cracked seeds, which are difficult to separate from the other components.

A surprisingly simple, quick and effective method for decorticating and hulling sunflower was discovered.sunflower seed decorticating machine The process involves infusing the sunflower with a cryogenically cooled liquid gas and then heating the infused sunflower by contacting it with a medium that is at least 100deg F. warmer than the liquid gas. The resulting thermal stress causes the sunflower to self-separate into fit, hulled seed meats and a mixture of hulls and nondecorticated sunflower.

The resulting sunflower kernels can be used for snacking or as a protein rich meal, and the hulls can be sold for a variety of purposes, including fuel. In the past, conventional mechanical decortication and hulling methods have been limited by the size of the shells, which make them difficult to separate from the seed meats. The new method overcomes these limitations by using a combination of cold temperatures and mechanical separation.

An lndian institute engaged in mechanical engineering R&D has developed the technology for twin roll decorticating machine, which is capable of processing 6000 kg of sunflower per hour. The patented technology can remove husks from sunflower seeds while leaving the seed meats intact, thereby facilitating a faster and more economical production of sunflower kernels for consumption or as fuel.

Besides sunflower, the huller can also be used to hull other seeds such as buckwheat, pumpkin seed, mung bean (green bean), hemp seed, job tears, Silybum seed, Gordon Euryale Seed and Jatropha seed. According to the company, the huller can be used to improve the quality of these products by increasing hulling efficiency and minimizing breakage of the seed meats. It can also be used to remove the hulls from the edible oil seeds in the oil expelling or oil expression process. A portable moisture meter can help in determining the moisture content of the seeds prior to harvesting and hulling. This can help in avoiding loss of valuable seeds. It can also be used to evaluate the condition of the hulls, such as their size, density, and color. A low hull content is desirable, as it will facilitate the extraction of high-quality oil. The huller can be modified to accommodate the various sizes of seeds.
