Problems solved by technology

With the development of edible fungi, there are more and more edible fungus residues, that is, the waste after cultivation of edible fungi. There are millions of tons of mushroom residues produced in my country every year, because most cultivators are not very aware of the nutritional value of mushroom residues. We understand that the residues of edible fungi are often discarded or burned anywhere. The residues still contain a large amount of mycelium and rich nutrients. Mold and pests are easy to multiply and proliferate in it. On the one hand, it has caused a huge resource waste Waste, on the other hand, due to the growth of mold and pests, is bound to increase the number of mold spores and pests in the air, causing air pollution

Abstract

The invention discloses a method for preparing machine-made charcoal from needle mushroom residues and relates to the technical field of machine-made charcoal preparation. The method comprises the following steps: (1) dissolving mushroom residues left after cultivated needle mushroom is mature into an acid liquid, carrying out ultrasonic stirring at 45-55 DEG C, after ultrasonic stirring treatment, cleaning with deionized water till a solution is neutral, further dissolving into a 8-10% sodium bicarbonate solution, carrying out ultrasonic stirring, and after stirring, cleaning with deionized water till the solution is neutral; (2) uniformly mixing the needle mushroom residues after acid liquid treatment with proteasem, amylase and cellulase to carry out a reaction; (3) carrying out carbonization treatment on the reacted product in a carbonization furnace, thereby obtaining the machine-made charcoal. The waste needle mushroom residues are turned into wealth, and not only is repeated useof resources achieved, but also the prepared machine-made charcoal product is high in yield, high in fixed carbon content and high in heat radiation.

Description

Technical field: [0001] The invention relates to the technical field of machine-made charcoal preparation, in particular to a method for preparing machine-made charcoal by utilizing mushroom residue of Flammulina velutipes. Background technique: [0002] Mechanism charcoal (machine-made charcoal), also known as machine-made charcoal, fuel sticks, artificial charcoal, regenerated charcoal, smokeless clean charcoal, stick charcoal raw materials from a wide range of sources, rice husk, peanut shells, cotton husks, corn cobs, corn stalks, sorghum Rods, etc. can be used as raw materials to produce stick charcoal, and sawdust, shavings, and bamboo chips are the best. Because the mechanism charcoal is smokeless, odorless and non-toxic, it has been widely used for home heating and barbecue food; in the industrial field, it can be used as industrial raw materials and further processed into activated carbon, etc. Due to its high density, high calorific value, smokeless, odorless, pol...
