Embodiment Construction

[0025] This process can effectively process the flaxseed on a laboratory scale or on a commercial scale, and separate various useful components extracted from the flaxseed.

[0026]This article describes a continuous dehulling process that separates the husk and kernel of flaxseeds. Useful products can then be extracted from various flaxseed ingredients, including a product with a high lignan content. In addition, this process can also separate the various components of the linseed hull, so as to obtain the hull part rich in lignans.

[0027] The invention provides a continuous processing method that can separate the linseed hulls and kernels. First, the linseed is dried to reduce the moisture content to about 0.5% to 3.0%; then, the dried linseed is continuously sent to a separation bin equipped with a coarse grinding spinner. In the separation chamber, the dried flaxseed passes through the coarse grinding rotator at an appropriate speed, so that the flaxseed can be dehulled by s...

Abstract

A continuous process for separating components of flaxseed is described. Flaxseed is dried to a moisture content of from about 0.5% to about 3.0%, after which is introduced into a separation chamber having an abrasive rotator therein. As the flaxseed passes over the abrasive rotator, contact with rotator separates the flaxseed components into hulls and kernels. Hulls and kernels are separated and may be used in this form or processed further. Hulls may be further processed by extraction with water and with hexane to remove flaxseed gum and oil, respectively. These two extractions may be done in any order. The process results in a lignan-rich component of flaxseed, a gum extract and oil. These separate components of flaxseed may be used in products such as feed, personal care products or nutraceuticals.

Description

[0001] According to the U.S. Patent Application No. 10 / 013,494 filed on December 13, 2001, this application enjoys U.S. patent priority. It is hereby declared that the entire content of this patent application is quoted here. Technical field [0002] The invention relates to the field of flaxseed processing technology, in particular to continuous dehulling, separating dehulled products, extracting and producing useful products that can be used as ingredients of medicinal nutrition, health food, feed and other edible and non-edible products. Background technique [0003] Flaxseed is one of the main crops in western Canada, northern America, South America and some European countries. Traditionally, flaxseed is generally used for oil extraction, and its meal can be used as animal feed. In recent years, the importance of flaxseed in the Western diet has increased because it contains a variety of nutrients that are very beneficial to human health, including linseed oil (42-46%) rich in...
