Problems solved by technology

The disadvantages of the above-mentioned method are: one, the linseed is also used for depressing oil after leaching and extracting gum, and this re-drying process will inevitably consume a large amount of energy, which is not desirable in industrialized production and economically; two, the above-mentioned methods are all It is a laboratory test and has not been produced in industry. From the perspective of its process, it is difficult to automate production, and it is mostly operated by a single machine or manually; 3. Its dry-in-dry method may cause gel denaturation; 4. The added sulfurous acid is harmful to practical products. , especially as a "green" food is unfavorable, because it brings in undue sulfite

preparation example Construction

[0006] The preparation of flax gum in the present invention is realized through the following technical scheme: first, the flaxseed is subjected to initial cleaning and screening, selective screening, stone removal and iron removal, and seed hull separation to obtain the flaxseed hull, and then the flaxseed hull is placed in the reaction kettle Heating water dipping in the dipping tank, using a scraper type dynamic separator to separate the glue from the linseed husk and kernel slag, the preparation method of the flax glue also includes the following steps: a step of concentrating, a step of heating the material liquid, and atomizing step, a drying step, collecting the product through cyclone separation to obtain flax gum.

[0007] The concentration is concentrated until the solid content of the feed liquid is 2-5%, the feed liquid is heated to 85-95°C, the instant drying temperature is 180-210°C, and the product yield is above 99%. .

Embodiment 1

[0009] The linseed is used as the raw material for primary screening, selection, stone removal and iron removal, and then the linseed husk and linseed kernel are separated by a seed husk separator. Add water to the soaking tank of the reaction kettle to naturally soak the gum in the linseed husk; use a scraper type dynamic separator to separate the glue from the linseed husk residue; The concentration accounts for 5%, and the concentrated glue solution is transported to the electric high-speed centrifugal atomizing nozzle in the top of the drying tower by the feeding pump, and the slurry is thrown out and atomized by the high-speed rotating centrifugal atomizing nozzle, and the atomized material liquid Move from top to bottom in the drying tower; the filtered cold air is sent to the air filter by the blower, heated by an electric heater, and then enters the hot air distributor at the top of the drying tower along the hot air flue, and is distributed through the hot air distribu...

Abstract

The invention discloses a method to extract flax glue from flax seed shell, which comprises the following steps: (1) cleaning raw material; de-stoning; (2) separating seed peel; (3) proceeding shell gumming; (4) separating the glue and peel shell slag; (5) condensing; (6) sprayed-drying. This invention can keep the getting ratio and quality of the flax seed, which possesses advanced craft, low cost and high quality.

Description

1. Technical field [0001] The invention relates to a production method of food gum. The method separates linseed husks from kernels, extracts linseed gum from the linseed husks, and sprays and dries to prepare the linseed gum. 2. Background technology [0002] Flax glue is a natural vegetable glue widely used in biology, food, pharmaceutical and other industries. Chinese patent CN1072184A discloses a method of directly extracting linseed with water (50°C-95°C) and adding sulfurous acid and citric acid as leaching aids to extract the colloid. The disadvantages of the above-mentioned method are: one, the linseed is also used for depressing oil after leaching and extracting gum, and this re-drying process will inevitably consume a large amount of energy, which is not desirable in industrialized production and economically; two, the above-mentioned methods are all It is a laboratory test and has not been produced in industry. From the perspective of its process, it is difficult...
