Problems solved by technology

At present, the treatment of filter cloth water mainly adopts aeration or oxidation pond treatment, cinder clarification and other methods, but these methods require a wide site, large investment, and high operating costs
[0006] CN104341236A discloses the preparation method and use of using bagasse as the cultivation substrate of oyster mushrooms. However, at present, there is no preparation method for the above four sugar-making by-products to be used for the preparation of edible fungus culture medium, especially for solids and organic matter. It is of high practical significance to develop a comprehensive utilization of by-products of sugar cane sugar production and convert them into edible fungus culture medium for the washing filter cloth water of sugar factories with high content, partial acidity, easy to be corrupted and polluted, and difficult to handle.
In addition, because bagasse contains a small amount of sugar, the bagasse accompanied by sugar-making wastewater is easily contaminated with bacteria, and the fibers are slender, and the added molasses has a high viscosity. The mixing process with existing equipment is likely to cause machine jams, and the efficiency is relatively low. Low, which brings a lot of trouble to the preparation of bagasse edible fungus culture medium

Abstract

The invention discloses a method for continuously and efficiently producing an edible fungus culture medium from sugarcane sugar refining byproducts. According to the method, a special dosing device for continuously producing the edible fungus culture medium is arranged on a bagasse discharging device in a sugarcane squeezing production line for dosing the sugarcane sugar refining byproducts (bagasse, molasses, filter mud and filter cloth washing water) according to a certain proportion so as to achieve automatic, continuous and efficient production of the edible fungus culture medium, and the culture medium is sterilized through evaporative sugar boiling afterheat, so that integration of sugar refining and the production of the edible fungus culture medium is achieved and a novel thought is provided for a sugarcane industry mode; the edible fungus culture medium produced by the method provided by the invention is reasonable in nutrition ratio, can meet nutrient elements needed in the growth stages of edible mushrooms, can increase the mushroom fruiting speed and shorten the cultivation cycle, and is high in bioconversion rate.

Description

technical field [0001] The invention belongs to the field of resource utilization of waste, and more specifically relates to a method for continuously and efficiently producing edible fungus culture medium by utilizing by-products of sugar cane sugar production. Background technique [0002] Edible mushrooms are rich in nutrition and delicious in taste, and have become a new favorite on people's tables. Today, the edible fungus industry has become the fifth largest planting industry after grain, oilseeds, fruits and vegetables, and it is also showing an increasing trend in terms of scale, output, quality, safety, processing and benefits. Bacteria factory production and processing technology put forward higher requirements. [0003] At present, the commonly used raw materials for edible fungus culture medium mainly include wood chips, crop straw, corn flour, soybean meal, distiller's grains, etc. However, the prices of some major cultivation raw materials continue to rise. ...
