Flaxseed Wheat Processing Line

Shijiazhuang Xinlu Technology Co., Ltd. – Technical Overview of Flaxseed Wheat Processing Line

The processing of flaxseed wheat, which involves handling both flaxseeds and wheat grains, often simultaneously or in parallel lines, requires a system designed to manage two distinct seed types with different physical properties and end-use requirements. Shijiazhuang Xinlu Technology Co., Ltd. designs integrated processing lines that can be configured to handle these seeds separately or to process blended products, focusing on achieving high purity, preserving oil content in flax, and ensuring the milling quality of wheat.

The initial stage for both materials is receiving and pre-cleaning. Raw flaxseed and wheat are typically received and stored separately. Each is passed through initial cleaning equipment, such as scalpers and pre-cleaners, to remove coarse impurities like straw, stalks, and large foreign materials. This step protects the more sensitive downstream equipment from damage and reduces the load for finer cleaning.

The core of the line splits into two parallel or sequential cleaning streams due to the significant difference in seed size, shape, and density. For wheat processing, the stream focuses on achieving grain suitable for milling or seed. This involves air-screen cleaners to remove chaff and dust, destoners to separate heavier stones, and gravity separators to remove lightweight, immature kernels. Indented cylinder separators may be used to remove other grains or weed seeds of similar size but different length.

For the flaxseed stream, the cleaning process is tailored to its small, flat, and oily nature. Dedicated fine air-screen cleaners with appropriately sized screens are used. Aspiration is critical to remove light debris and dust, which can be abundant. Specific gravity separators are highly effective for flaxseed, efficiently upgrading the lot by removing shriveled seeds, sand, and other density-based impurities. Given the high value of flaxseed for oil, gentle handling throughout is paramount to prevent cracking.

Conditioning is a key stage, especially if the line is designed for oil extraction. For flaxseed, conditioning involves adjusting the moisture and temperature to optimize oil yield and quality for subsequent pressing. For wheat destined for milling, conditioning (tempering) is essential to toughen the bran and mellow the endosperm for optimal flour extraction. These conditioning systems are precisely controlled.

The final stages involve finishing and packaging. Cleaned and conditioned flaxseed may be directly packaged for sale, sent to an oil pressing plant, or further processed into ground meal. The processed wheat is either bagged as clean seed or conveyed to a milling section for flour production. The entire integrated line from Shijiazhuang Xinlu Technology Co., Ltd. is controlled via a central system, allowing for flexible operation and clear separation of the two product streams to prevent cross-contamination, ensuring that both the flaxseed and wheat meet their respective quality standards.
