Embodiment 1
[0024] A processing method for banana leaf sheaths, specifically comprising the steps of:
[0025] 1) Raw material processing: After the bananas are harvested, cut the banana trunk from the root, remove the leaves, place the banana stem flat on the ground, and cut it along the longitudinal surface of the banana stem with a knife to a depth of 1% of the banana stem. / 2, then split the banana tree stem with both hands along the slit, take out the core of the banana stem, and the banana leaf sheath will come off one by one to remove the rotten, deteriorated leaf sheath and other impurities;
[0026] 2) Remove water: Feed the banana leaf sheath inner membrane layer obtained in step 1 downwards, starting from the tail end, one by one into the press, and when the upper and lower rollers clamp the raw materials, straighten and feed the materials, and repeat the cycle. operation to remove moisture;
[0027] 3) modification treatment: to the banana leaf sheath surface that step 2) obt...

Abstract
The invention discloses a processing method for banana leaf sheaths. The method specifically includes the steps of: 1) raw material treatment: after banana harvesting, stripping banana leaf sheaths one by one, removing rotten and deteriorated leaf sheaths and other impurities; 2) water removal: remove water from the banana leaf sheaths obtained in step 1); 3) modification treatment: spraying a layer of modifier to the surfaces of the banana leaf sheaths obtained in step 2), with the modifier being a mixed water solution of urea formaldehyde resin and polyamide in a mass ratio of 1:1-2 and having a mass concentration of 0.1-0.5%, and performing standing; 4) drying: drying the banana leaf sheaths obtained in step 3); 5) bundling and warehousing: collecting the dry banana leaf sheath products obtained in step 4), stacking them neatly and bundling them together, concentrating the banana leaf sheaths, and then carrying out warehousing dry storage. The method provided by the invention employs the modifier composed of urea formaldehyde resin and polyamide to treat banana leaf sheaths and can increase the toughness and color of the banana leaf sheaths.
Description
technical field [0001] The invention relates to the technical field of agricultural products, in particular to a method for processing banana leaf sheaths. Background technique [0002] Banana is one of the four famous fruits in southern my country, with an annual planting area of about 200,000 hectares, mainly distributed in some southern provinces such as Guangdong, Guangxi, Fujian, Hainan, and Yunnan. After the bananas are harvested every year, a large number of banana pseudostems, also called banana leaf sheaths, that is, banana stems (leaves and leaf sheaths) are treated as waste, left in the fields, corners or piled up next to the ditch, and allowed to rot naturally. Pubei County, Qinzhou is one of the largest banana production base counties in the country. It is known as the "Hometown of Bananas" in China. The county has a planting area of about 10,000 hectares and an annual output of 375,000 tons of bananas. According to statistics, there are more than 160 milli...
