Problems solved by technology

However, the components in the spent bacteria sticks are complicated, and there may be more impurities in the hot water extract, and the extract needs to be further purified; and the extraction by water extraction and alcohol precipitation is affected by the amount of ethanol, extraction time and temperature. Influenced by three factors, it is difficult to guarantee a high and stable extraction rate in actual extraction

Embodiment 1

[0034] Embodiment 1: a kind of multi-stage recovery processing method of discarded mushroom stick, comprises the following steps:

[0035] Step 1: Pretreatment of waste mushroom sticks

[0036] Collect the discarded shiitake mushroom sticks and remove the external culture belt, then put them into the sterilization equipment 1 for sterilization, and then wash and dry the sterilized discarded shiitake mushroom sticks in the cleaning / drying equipment 2 Pulverize to obtain the end of the bacterium stick;

[0037] Step 2: Primary processing

[0038] Put the crushed bacterium sticks in the fermentation equipment 3 for fermentation and then filter to separate the fermentation liquid from the fermentation residue. The specific fermentation steps are: put the crushed bacterium sticks in the fermentation equipment 3 for fermentation and then add and Cellulase with a volume ratio of 0.05% of the fermented product and pectinase with a volume ratio of 0.03% of the fermented product were ...

Abstract

The invention discloses a multi-stage recovery treatment method and device for waste shiitake mushroom sticks. The method comprises the following steps: sterilizing, cleaning, drying and crushing thewaste shiitake mushroom sticks; performing fermentation and centrifugation to obtain a primary residual material and a concentrated solution; extracting the primary residual material, and then performing filtration through an ultrafiltration membrane to obtain a treatment solution; carrying out alcohol precipitation on the concentrated solution and the treatment solution, centrifuging to obtain aprecipitate, and carrying out spray drying to obtain lentinan. The device comprises sterilization equipment, cleaning/drying equipment, fermentation equipment, centrifugal equipment, extraction equipment, a reaction kettle, ultrafiltration equipment and spray drying equipment. The waste shiitake mushroom sticks are subjected to polysaccharide extraction in a mode combining alcohol extraction afterfermentation, the problem that the shiitake mushroom sticks are complex in component and difficult to extract is effectively solved, and the high and stable extraction rate can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of recycling shiitake mushroom sticks, in particular to a method and device for multi-stage recovery and treatment of discarded shiitake mushroom sticks. Background technique [0002] Abandoned shiitake mushroom sticks are discarded mushroom sticks after harvesting of shiitake mushrooms. The use of mushroom sticks is huge. According to statistics, the number of waste mushroom sticks produced in the country is as high as 60 billion sticks every year, and the annual consumption of mushroom sticks in some major mushroom cultivation areas reaches 600 million sticks. Improper handling of shiitake mushroom sticks will not only cause a serious waste of resources, but also increase environmental pollution; in recent years, the reuse of shiitake mushroom sticks is mainly concentrated in livestock and poultry feed, fertilizer and regeneration medium for edible fungi, etc. However, there are few reports on the extract...
