Problems solved by technology

The direct silage technology of fresh banana stems and leaves is easy to promote and industrialize. Although there are reports of direct silage, the quality of the silage is average and it is not suitable for long-term storage.
It is suitable for silage by reducing its moisture content by drying, but due to the limitation of weather and site, banana stems and leaves are very easy to rot and deteriorate during the drying process
If it is mixed with other raw materials with low moisture content (such as straw, dry cane tips, etc.), the cost of purchasing and transporting other raw materials and labor costs will be increased.
In addition, banana stems and leaves contain a lot of tannins, and the drying process is equivalent to concentrating tannins, which reduces the nutritional quality of banana stems and leaves silage and affects the palatability
Therefore be badly in need of a kind of method, can solve above-mentioned banana stem and leaf silage perishable, be difficult to store for a long time and the problem of high tannin content

Embodiment 1

[0020] A method for co-producing silage and vegetable tanning agent with full components of banana stems and leaves, comprising the following steps:

[0021] (1) Crushing and pressing: first crush the whole banana stems and leaves to 2~5cm, add 6% rice husks by weight of the banana stems and leaves after crushing, and then squeeze them to a moisture content of about 60% by a double screw press, respectively Collect the solid residue and liquid residue of banana stems and leaves;

[0022] (2) Treatment of solid residue: first brewing glutinous rice and filtering off the glutinous rice wine to prepare wet distiller's grains; mixing lactic acid bacteria, tanninase, wet distiller's grains and citric acid to prepare a compound silage agent. The process is as follows, dissolving 5g of lactic acid bacteria In 1 liter of sugar water, each liter of sugar water contains 150 g of molasses. After sealed fermentation for 24 hours, add 5 g of tannase, 30 g of wet distiller’s grains and 35 g of c...

Embodiment 2

[0025] A method for co-producing silage and vegetable tanning agent with full components of banana stems and leaves, comprising the following steps:

[0026] (1) Crushing and pressing: first crush the whole banana stems and leaves to 2~5cm, after crushing, add 5% rice husks by weight of the banana stems and leaves, and then squeeze them with a double screw press to a moisture content of about 70%, respectively Collect the solid residue and liquid residue of banana stems and leaves;

[0027] (2) Treatment of solid residue: firstly brew the glutinous rice and filter the glutinous rice wine to obtain wet distiller's grains; mix lactic acid bacteria, tanninase, wet distiller's grains and citric acid uniformly to prepare a compound silage agent. The process is as follows, dissolve 2g of lactic acid bacteria In 1 liter of sugar water, each liter of sugar water contains 160g of molasses. After sealed fermentation for 24 hours, add 15g of tannase, 20g of wet distiller’s grains and 25g of c...

Embodiment 3

[0030] A method for co-producing silage and vegetable tanning agent with full components of banana stems and leaves, comprising the following steps:

[0031] (1) Crushing and pressing: first crush the whole banana stems and leaves to 2~5cm, add rice husks of 4% by weight of banana stems and leaves after crushing, and then squeeze them to about 75% moisture content by double screw press, respectively Collect the solid residue and liquid residue of banana stems and leaves;

[0032] (2) Treatment of solid residue: firstly brew the glutinous rice and filter the glutinous rice wine to obtain wet distiller's grains; mix lactic acid bacteria, tanninase, wet distiller's grains and citric acid uniformly to prepare a compound silage agent. The process is as follows, dissolve 2g of lactic acid bacteria In 0.5 liter of sugar water, each liter of sugar water contains 140g of molasses. After sealed fermentation for 24 hours, add 5g of tannase, 20g of wet distiller’s grains and 25g of citric acid...

Abstract

The invention discloses a method for co-producing silage and a vegetable tanning agent by all components of banana stems and leaves. The method comprises the following steps: (1) crushing and squeezing; adding rice husks in a squeezing process and collecting solid residues and liquid residues of the banana stems and leaves respectively; (2) treating the solid residues: carrying out silage fermentation on the banana stems and leaves by utilizing a compound ensiling agent; adding the ensiling agent prepared by compounding 2g to 5g of lactic acid bacteria, 5g to 15g of tannase, 20g to 30g of wet vinasse and 25g to 35g of citric acid into each ton of the solid residues of the banana stems and leaves; (3) treating the liquid residues: filtering, vacuumizing and concentrating and spraying and drying the liquid residues of the banana stems and leaves to obtain the vegetable tanning agent. According to the method disclosed by the invention, the content of tannin in the silage is effectively reduced and the palatability of the silage is increased; the vegetable tanning agent is produced by utilizing the liquid residues containing a lot of the tannin so that all-component recycling utilization of the banana stems and leaves is realized.

Description

Technical field [0001] The invention relates to the technical field of resource utilization of agricultural wastes, in particular to a method for co-producing silage and vegetable tanning agent with full components of banana stems and leaves. Background technique [0002] Banana stems and leaves are huge agricultural wastes produced after banana fruit picking. Feeding is an effective way of high-value utilization. Banana stem and leaf silage is suitable for daily feeding of ruminants such as cattle and sheep, and has attracted more and more attention. The moisture content of fresh banana stems and leaves is usually 93-97%, and such a high moisture content is not suitable for direct use in silage. The direct silage of fresh banana stems and leaves is easy to promote and industrialize. Although there are reports of direct silage, the quality of silage is average and it is not suitable for long-term storage. The moisture content is reduced by drying to make it suitable for silage....
