Embodiment 2

[0016] Embodiment 2, take 100kg of yellow garlic waste, add 100kg of water after cleaning, crush it, place it in the water distillation kettle for producing essential oil, directly pass into the steam heating in the kettle, after boiling, pass cooling water in the condensation pipe, control the cooling water The speed of the feed is such that the temperature of the outflowing liquid after condensation is 35-40 ° C. Collect the condensed liquid in a stainless steel container and let it stand for a period of time. A layer of yellow oily substance appears at the bottom of the condensed liquid. Separate and collect this part of the oily substance, that is It is garlic oil; the distillation time is 4 hours, and 100kg garlic yellow waste can be distilled to obtain 2kg garlic oil; release the material in the distillation kettle, transfer it to a 1000L hydrolysis tank, add water to make the volume of the material and moisture reach 500L, and wait for the Cool to 40-45°C, first add 100g...

Embodiment 3

[0017] Embodiment 3, get garlic yellow waste 100kg, after cleaning, crush, place in the water still of producing essential oil, feed steam heating directly in the still, after boiling, pass cooling water in the condensing pipe, control the feeding of cooling water Speed, so that the temperature of the outflowing liquid after condensation is 35-40 ° C, collect the condensed liquid in a stainless steel container, stand still for a period of time, a layer of yellow oily substance appears at the bottom of the condensed liquid, separate and collect this part of the oily substance, it is garlic oil Distillation time is 3 hours, and 100kg garlic yellow waste can be distilled and obtain 1kg garlic oil; Emit the material in the still, transfer in the hydrolysis tank of 1000L, add water and make the volume of material and moisture reach 300L, wait for the material temperature to cool down to 40-45°C, first add 50g of 1398 neutral protease, the specification of the enzyme is 30000IU / g, ke...

Abstract

The invention discloses a method for producing fuel alcohol by fermenting blanched garlic leaf wastes. The method is characterized by comprising the following process steps: treating blanched garlic leaf wastes; heating and condensing; standing for separation and distilling; hydrolyzing; and fermenting and distilling. The method has the following characteristics and progresses: not only can wastes be turned into wealth and environmental pollution be improved, but also the problem that grains are consumed for producing the fuel alcohol at present can be solved; and meanwhile, the factors inhibiting yeast growth are eliminated so as to ensure that fermentation can be carried out smoothly, and costly garlic essential oil is prepared, thus getting a double advantage.

Description

Technical field: [0001] The invention relates to the technical field of fuel production, in particular to a method for producing fuel alcohol by fermenting garlic yellow waste. Background technique: [0002] Garlic yellow is the seedling of garlic. Because it is cultivated in the greenhouse in winter to avoid sunlight, the garlic leaves are tender yellow and the texture is relatively tender. Good-quality garlic yellow is soft and tender, the plant is fat and strong, the leaves are waxy yellow, the tip of the leaf is slightly purple, the base is tender and white, the tip of the leaf is not rotten, not dry, full of fragrance, not strong spicy. It is a delicious edible vegetable. The development of garlic yellow industry in recent years has driven farmers around the production area to adjust the agricultural industry structure spontaneously, and absorbed a large number of migrant workers to solve the problem of labor transfer and employment. It is a good industry that promotes...
