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 method and device for multi-stage recovery and treatment of discarded mushroom sticks; the method comprises: pretreatment of sterilizing, cleaning, drying and pulverizing waste mushroom sticks; fermenting and centrifuging to obtain primary residue and concentrated liquid ; The primary residual material is leached and filtered through an ultrafiltration membrane to obtain a treatment solution; the concentrated solution and the treatment solution are alcohol-analyzed and centrifuged to obtain a precipitate that is spray-dried to obtain lentinan; the device includes sterilization equipment cleaning / drying equipment Fermentation equipment, centrifuge equipment, extraction equipment, reaction kettle, ultrafiltration equipment, spray drying equipment; the present invention adopts the combined method of alcohol extraction after fermentation to extract polysaccharides from discarded mushroom sticks, effectively solving the problem of complex components of mushroom sticks. For difficult-to-extract problems, it can effectively guarantee a high and stable extraction rate.

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...
