Mat grass harvesting and drying process

Abstract

The invention discloses a mat grass harvesting and drying process. The process comprises the steps of bundling harvested and cleaned mat grass through an automatic mat grass bundling device to obtaingrass bundles, vertically placing the grass bundles, and draining; and after taking out a bundling cylinder of each grass bundle from a center shaft, vertically placing the grass bundles into a dryingoven preheated to 85 to 90 DEG C, firstly drying the grass bundles for 20 to 25min, then cooling the grass bundles to 60 to 70 DEG C, continuously conducting drying for 3h to 4h, naturally cooling the grass bundles to the room temperature, taking out the grass bundles, and accomplishing drying. According to the mat grass harvesting and drying process provided by the invention, the mat grass is bundled into the grass bundles through the special automatic mat grass bundling device, and mat grass bundling does not need to be conducted manually, so that the bundling speed is greatly increased, and the bundling efficiency is improved; two-section temperature control is adopted for drying, so that the original color of the mat grass is retained furthest; and the bundling cylinder used in the automatic mat grass bundling device is further applicable to the drying tank, so that a harvesting process and a drying process are smoothly connected.

Description

technical field [0001] The invention belongs to the technical field of mat grass processing, and in particular relates to a harvesting and drying process of mat grass. Background technique [0002] Mat grass, commonly known as stone grass, or Lin in ancient times, is a perennial swamp herb. The stems of mat grass are smooth and slender, uniform in thickness, thin in wall and sparse in core, moderate in hardness and softness, long in fiber, full of elasticity, good in tensile resistance, bright in color and rich in fragrance. It is one of the excellent natural green plant fibers, very suitable for weaving mats. [0003] Mat grass is generally harvested in June. The harvesting process is generally: first mow the grass with mud, wash the grass in time, and shake off the dead yellow grass; [0004] Due to the long stems of mat grass, the current growers mainly use natural drying, and seldom use mechanical equipment for drying. For example, the Chinese invention patent applica...

Problems solved by technology

However, the drying process still has the following disadvantages: when drying, directly put the grass handles with a diameter of 20 to 25 cm into the oven, because the diameter of the grass handles is relatively large and the structure is relatively compact, resulting in the drying of the grass handles during the drying process. The drying process inside and outside the straw is different, and the degree of drying is different; this leads to the need to take other protective measures for the mat grass on the outer layer of the straw handle in this process, such as immersing the straw handle in a specific gravity of 1.2 In the light gray-white clay magnet colloid, such as lowering the drying temperature and prolonging the drying time, etc.

Not only the entire drying process is very complicated, but also time-consuming, labor-intensive, and consumables
