Embodiment 1

[0023] Add 10kg of guar gum endosperm sheets after winnowing into the stirring device, add 9kg of water, and the temperature is 40 0 C. Stir for 75 minutes; add the swollen guar gum endosperm slices to a twin-screw extruder for extrusion, the screw speed is 120rpm, the length-to-diameter ratio (L / D) is 13:1, and three sets of extrusion are set on the twin-screw Wedge module, twin-screw extruder jacket through cooling water, control temperature at 80 0 Below C, snowflake-like thin film is obtained; air-drying, about 20% water content of guar gum dry film; use JCBM-760 type pulverizer to powder, control the water content below 10% by adjusting the air volume, and adjust the powder connection rate to 85%. More than 99% of the crushing fineness passed through a 180-mesh sieve to obtain 8.8 kg of high-quality guar gum powder.

Embodiment 2

[0025] Add 10kg of guar gum endosperm sheets after winnowing into the stirring device, add 8kg of water, and the temperature is 50 0 C. Stir for 60 minutes; add the swollen guar gum endosperm slices to the twin-screw extruder for extrusion, the screw speed is 200rpm, the length-to-diameter ratio (L / D) is 15:1, and three sets of extrusion are set on the twin-screw Wedge module, twin-screw extrusion equipment jacket through cooling water, control temperature at 80 0 Below C, snowflake-like thin film is obtained; air-drying, guar gum dry film with a moisture content of about 10% is obtained; use JCBM-760 type pulverizer to powder, control the moisture below 10% by adjusting the air volume, and adjust the powder collection rate to 80%. More than 99% of the crushing fineness passed through a 180-mesh sieve to obtain 8.9 kg of high-quality guar gum powder.

Embodiment 3

[0027] Add 10kg of guar gum endosperm slices after winnowing into the stirring device, add 12kg of water, and the temperature is 30 0 C, stirring for 90 minutes; add the swollen guar gum endosperm slices to a twin-screw extruder for extrusion, the screw speed is 300rpm, the length-to-diameter ratio (L / D) is 16:1, and three sets of extrusion are set on the twin-screw Wedge module, twin-screw extrusion equipment jacket through cooling water, control temperature at 80 0 Below C, snowflake-like thin film is obtained; air-drying, about 30% water content of guar gum drying film; use JCBM-760 type pulverizer to powder, control the water content below 10% by adjusting the air volume, and adjust the powder collection rate to 90%. More than 99% of the crushing fineness passed through a 180-mesh sieve to obtain 8.7 kg of high-quality guar gum powder.

Abstract

The invention discloses a preparing technology of high-quality guar gum powder. The preparing technology comprises the following steps of conducting hydration, wherein 10 parts of guar gum endosperm splits are added into 8-12 parts of warm water with the temperature being 30-500 C, and then the guar gum endosperm splits are stirred for 60-90 minutes for use; breaking walls, wherein the guar gum endosperm splits which are subjected to hydration are added into double-screw texture extruding equipment to be extruded, so that thin gum sheets or gum threads are obtained; conducting drying, wherein the extruded thin gum sheets or gum threads are dried by hot air flow, and the moisture is controlled to be 10%-30%; conducting powdering, wherein the dried gum sheets are smashed and powdered to obtain the product. Compared with a traditional technology in which powdering is directly conducted, power dissipation in the new technology is almost equal to that in the traditional technology, while the product production cost is hardly ever increased; the intracellular gum releasing rate reaches 85% or above; a pure physical method is adopted to produce the high-quality guar gum powder, no chemical agent is added, compared with guar gum first-grade gum powder home and broad, 1% gum liquor viscosity can be increased to 50% or above, and the water insoluble matter can be lowered to 20% or above.

Description

technical field [0001] The invention belongs to the field of food additive processing, and in particular relates to a preparation process of high-quality guar gum powder. Background technique [0002] Guarcan gum is a kind of galactomannan gum. Its structure and properties have been studied a lot. Big. The production of guar gum is mainly concentrated in India and Pakistan, and the quality of its products is uneven. Viscosity is an important index to evaluate the quality of galactomannan gum. The greater the viscosity of the glue, the less consumption of polysaccharide gum for the application industry with the same rheological requirements. Water insoluble matter is another important factor affecting product quality. At present, there are few reports on the research and production of high-quality guar gum, and there is no report on the research on the insoluble components of polysaccharide glue. Therefore, it is of great significance for the food processing industry to i...
