Problems solved by technology

The drying process largely determines the toughness, storage time and weaving quality of the stalks. The existing method is usually a rough exposure treatment, which is prone to uneven strength, easy cracking, and low flexibility of the treated cattail grass. Poor, long processing time and other problems, the loss rate of cattail grass due to improper drying treatment method is more than 10%, which reduces the utilization rate of materials

Embodiment 1

[0026] A drying method for cattail grass, comprising the steps of:

[0027] (1) The first stage of drying:

[0028] a. Wash the harvested fresh cattail grass and control the water for later use;

[0029] b. Take the following materials by weight: 7 parts of plant ash, 3 parts of isoamyl acetate, 2 parts of dihydroactinolactone, 2 parts of fatty acid glycerides, 3 parts of propylene glycol fatty acid esters, 120 parts of water;

[0030] c. Mix the ingredients described in operation b together, and then stir evenly at a speed of 830 rpm to prepare a primary treatment solution for later use;

[0031] d. Put the cattail grass treated in operation a into the drying room, keep the vacuum degree in the drying room at 0.07MPa, and the temperature at 46°C, and spray the primary treatment solution prepared in operation c on the surface of the cattail grass every 12 minutes, each time per kilogram of cattail grass The amount of spraying is 0.2kg until the water content of cattail g...

Abstract

The invention discloses a drying method for Typha angustifolia. The drying method comprises the following steps: (1) first-stage drying; (2) second-stage drying; and (3) third-stage drying. Each stage of the method is carried out on the basis of the characteristics of drying of Typha angustifolia; through the steps, the drying time for Typha angustifolia in the invention is shortened by 30% or more compared with conventional methods, the loss rate of Typha angustifolia is reduced by about 3%, the mechanical properties like flexibility and strength of Typha angustifolia are excellent and stable, and dried Typha angustifolia has a uniform and consistent color as a whole and is not prone to mildew or color changing after long-term storage; and high-quality and detailed technical support is provided for drying of Typha angustifolia, and the method has good promotion value.

Description

technical field [0001] The invention relates to a processing technology of cattail grass, in particular to a drying method of cattail catkins. Background technique [0002] Cattail grass, whose scientific name is Typha orientalis Presl, mostly grows by itself in watersides or ponds, and is widely distributed in East China and South China. Because of its good properties, rush grass is used as an important material for weaving straw mats, straw sandals, straw hats and other traditional utensils. [0003] Cattail grass needs to be dried before weaving. Generally, the water content of cattail grass just after harvesting is relatively high, about 65%, so it needs to be dried before storage, weaving and other operations. Usually, its water content needs to be reduced to below 20%. . The drying process largely determines the toughness, storage time and weaving quality of the stalks. The existing method is usually a rough exposure treatment, which is prone to uneven strength, easy...
