Embodiment 1

[0027] Remove the leaves from the harvested banana trees to obtain the banana stem and peel off the outer layer, and cut into 0.3m sections, then cut into 0.5mm thick slices on a slicer, heat the stem slices in hot water at 100°C After scalding for 10 minutes, take it out and beat it with a beater for 10 minutes, use a colloid mill to homogenize the obtained slurry, control the cycle at 5 times, and control the solid content at 5%, then pour the slurry into a filter bag for centrifugal dehydration, Divide the dehydrated filter cake into small pieces and then dry it with hot air. The drying temperature is 60°C, the drying time is 12 hours, and the moisture content is controlled within 5%. The dried material is crushed and sieved by a traditional Chinese medicine grinder to obtain banana stems. dry powder.

Embodiment 2

[0029] Remove the leaves from the harvested banana tree to obtain the banana stem and peel off the outer layer, and cut into 0.5m sections, then cut into 0.8mm thick slices on a slicer, heat the stem slices in 100°C hot water After scalding for 10 minutes, take it out and beat it with a beater for 10 minutes, use a colloid mill to homogenize the obtained slurry, control the cycle at 5 times, and control the solid content at 3%, then pour the slurry into a filter bag for centrifugal dehydration, Divide the dehydrated filter cake into small pieces and then dry it with hot air. The drying temperature is 70°C, the drying time is 10 hours, and the moisture content is controlled within 5%. The dried material is crushed and sieved by a traditional Chinese medicine grinder to obtain banana stems. dry powder.

Embodiment 3

[0031] Remove the leaves from the harvested banana tree to obtain the banana stem and peel off the outer layer, cut into 0.5m sections, then cut into 1mm thick slices on a slicer, and blanch the stem slices in hot water at 100°C 10min, after pulling out, beating with a beater for 10min, homogenizing the obtained slurry with a colloid mill, controlling the cycle at 8 times, and controlling the solid content at 3%, then pouring the slurry into a filter bag for centrifugal dehydration, and The dehydrated filter cake is divided into small pieces and then dried with hot air. The drying temperature is 80°C, the time is 10 hours, and the moisture content is controlled within 5%. The dried materials are crushed and sieved by a traditional Chinese medicine grinder to obtain banana stems. powder.

[0032] The banana stem powder obtained by the preparation method of the invention is light green and has the natural smell of the fragrant banana stem, and can be used as a raw material of di...

Abstract

The invention provides a preparation method of banana stem powder. The preparation method comprises the following steps of removing leaves from harvested banana trees so as to obtain banana stems, stripping outer layers, cutting the banana stems without the outer layers into segments, and cutting the segments into slices with a slicing machine; blanching the stem slices in hot water, fishing out the blanched stem slices out of the hot water, pulping the stem slices fished out of the hot water into serosity with a pulping machine, and then performing homogenizing treatment on the obtained serosity with a colloid mill; then pouring the serosity after homogenizing treatment into a filter bag for centrifugal dewatering so as to obtain a filter cake; and dividing the dehydrated filter cake into small blocks, performing hot air drying on the small blocks, crushing the dried materials with a crusher, and screening the crushed materials so as to obtain banana stem powder.

Description

technical field [0001] The invention relates to the field of agricultural waste reuse, in particular to a method for preparing dried banana stem powder. Background technique [0002] my country is a big banana planting country, which produces a large amount of banana tree waste resources every year. As a tropical herbaceous crop, banana has the characteristics of fast growth and high biological yield. During the banana harvest season, a large number of banana trees are cut down, and the banana trees are piled up as waste. High content, the rate of decay is very slow. Sun-drenched, necrotic banana stems are easy to nourish pathogens after fermentation. In 2011, only Hainan Province had a planting area of ​​750,000 mu. According to preliminary estimates, 120 banana trees are planted per mu, and each plant can produce 500g of waste (dry basis). It is conservatively estimated that 40,000 to 50,000 tons of banana trees are discarded every year in Hainan alone. The abandonment ...
