Abstract

The invention relates to a Chinese pennisetum drying method which is characterized in that a Chinese pennisetum drying device is provided. The Chinese pennisetum drying method includes steps of (1) mowing: Chinese pennisetum plants are mowed when Chinese pennisetum grows to be 1.5-2.5m high; (2) pulping: Chinese pennisetum is made to be grass pulp through a pulping machine without water; (3) flat laying: the grass pulp is flat laid on all layers of drying beds of drying bed frames, and the weight of the grass pulp on each drying bed frame is preferentially 5kg / m<2>-15kg / m<2>; (4) ventilating: upper layer hot air in a greenhouse is blown into grass pulp stacks for ventilating for 20-40 min by opening an air blower at the interval of 0.5-1.5 h; (5) turning: the grass pulp stacks are plowed and harrowed for one to three times every day; and (6) drying: the grass pulp stacks are dried for 3-7 days until the grass pulp is dried to be grass powder with 10-15% of water content, and then the grass powder can be stored or used. The Chinese pennisetum drying method has the advantages of being simple in process, high in drying efficiency, short in drying period and low in cost, being favorable for storing Chinese pennisetum nutrient substances and the like.

Description

technical field [0001] The invention relates to a method for drying pennisetum. Background technique [0002] Pennisetum has the characteristics of high yield and high quality, and is a high-quality pasture widely planted in the south. The stems of Pennisetum grass are strong and have high water content, and the proportion of stems generally accounts for more than 50% to 60%. Therefore, if the traditional pasture drying methods are adopted: such as cutting the whole plant to dry in the sun or heating and drying, there are problems such as difficult drying of grass stems, long drying cycle, nutrient loss or high drying cost. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a kind of simple process, high drying efficiency, short drying cycle, which is beneficial to preserve the nutrients of Pennisetum chinen...
