Embodiment 1

[0042] Take the waste tobacco stems produced by the threshing and redrying factory, the raw material particle size is about 0.3-5.0cm, and the moisture content is 11.3%; send the waste tobacco stems into the steam dampening drum, adjust the moisture content to 16%, and then send them into the grinder Crush it to a powder with a particle size of about 0.5-3.0mm, and dry it with hot air until the water content is 12-15%, that is, the tobacco stem feed is obtained, and it is set aside. After analysis, the nutrient content of the feed is: 20.5% of water-soluble total sugar, 9.2% of protein, 7.8% of pectin, 7.6% of organic acid, 2.5% of potassium, 2.0% of chlorine, 29.0% of tobacco stem fiber, 9.1% of ash, pH 5.5; The appearance is light brown, with a slight sweet tobacco and hay aroma.

[0043] Adopt the prepared tobacco stem feed to raise Tenebrio molitor, including the following two stages:

[0044] (1) Domestication and cultivation of seed insects: the first time to use tobacc...

Embodiment 2

[0061] Take 1500kg of waste tobacco stems produced by the threshing and re-baking factory, the raw material particle size is about 0.3-5.0cm, and the moisture content is 11.3%; mix it with 1000kg of water and 5kg of active yeast liquid, and wait until the tobacco stems fully absorb the water. Heap and ferment at 20-40°C for 6 days, then send it to a pulverizer and crush it into crumbs with a particle size of about 1.0-5.0mm, and dry it with hot air until the moisture content is 12-15%. After analysis, the nutrient content of the feed is: 15.2% of water-soluble total sugar, 15.7% of protein, 3.8% of pectin, 8.2% of organic acid, 2.7% of potassium, 2.2% of chlorine, 27.0% of tobacco stem fiber, pH 5.0; the appearance is brown , with a slight tobacco sweet aroma and fermentation aroma; then adopt the method of Example 1 to breed Tenebrio molitor.

Embodiment 3

[0063] Take 1,000kg of waste tobacco stems produced by the threshing and redrying plant, add 10,000kg of water, extract at room temperature for 24 hours, then drain the material, squeeze or centrifuge for solid-liquid separation, and obtain the extraction liquid and solid-phase tobacco stem waste. Stems; solid-phase tobacco stems are stacked and fermented at 20-40°C for 3 days, then sent to a pulverizer, kneading machine or defibrillator to make fluffy fibers or crumbs, and then dried to a moisture content of 10-25% Tobacco stem feed, ready for use; the tobacco stem extract is added to yeast, fermented at 25-30°C for 2 days to produce yeast cell protein, and the cell protein is separated by precipitation, press-filtered and dried, and blended into tobacco stem In the feed; Then the barley worm is cultivated with reference to the method of embodiment one.

Abstract

The invention provides a biological utilization method of waste tobacco stems. In the biological utilization method, the waste tobacco stems produced in the tobacco threshing and redrying process are used as a main raw material for preparing insect feed by a comminution or fermentation method, and the insect feed is mixed with conventional feed for breeding yellow mealworms, barley insects, dark mealworms, woodlouses, crickets, earthworms and other economic insects. The biological utilization method comprises the main steps: preparing tobacco stem feed; mixing the feed; breeding the insects; and utilizing the insects. Polypides of the produced insects are applicable to the breeding industry, and fecula is applicable to organic agricultural tobacco production. Through the food-taking process of the insects and the very strong decomposing and digesting capability of the insects, the waste tobacco stems are biologically transformed into of insect polypides with multiple purposes and products thereof and are organically connected with the livestock and poultry breeding industry and other industrial chains, so that the waste tobacco stem biomasses can be sustainably recycled, with high efficiency, no pollution and no discharge and good economic, environmental and social benefits are produced.

Description

technical field [0001] The invention relates to the technical field of utilization of biomass waste, in particular to the technical field of biological utilization of tobacco waste and insect feeding methods. Background technique [0002] my country is a large tobacco producing country. In recent years, due to the comprehensive promotion of tobacco threshing and redrying process, a special kind of tobacco stem by-products are produced in large quantities. These tobacco stem resources are concentrated, and the particle size (generally between 0.3 and 5.0cm) is uniform. Tobacco stems are rich in protein, sugar, lignin, cellulose, organic acids, pectin, etc., and the content of nitrogen, phosphorus, and potassium is significantly higher than that of grain crop straw, especially the total nitrogen is 1.5-3%, and the total sugar Up to 10-20%, total potassium up to 2-5%, is a valuable biological resource. Hundreds of thousands of tons of by-products of tobacco stalks are produced...
