Secondary fermenting tunnel device for edible pleurotus cornucopiae compost

Abstract

The invention discloses a secondary fermenting tunnel device for an edible pleurotus cornucopiae compost. The secondary fermenting tunnel device is characterized in that a top plate of a fermenting tunnel sequentially consists of a first concrete layer, first polystyrene plate heat insulation layers, first furnace slag bedding layers and waterproof layers from the middle layer to the two side outer layers; a wall body of the fermenting tunnel sequentially consists of a second concrete layer, second polystyrene plate heat insulation layers and brick masonry layers from the middle layer to the two side outer layers; a high-pressure air spray pipeline system sequentially consists of a third concrete layer, a heat insulation layer and a second furnace slag bedding layer from top to bottom; andhigh-pressure air spray nozzles and an air ventilating pipe are arranged in the third concrete layer. According to the secondary fermenting tunnel device disclosed by the invention, heat produced byfermenting temperature in a fermenting process of the mushroom compost is fully utilized, protected and stored in the fermenting tunnel; a secondary fermenting tunnel for pasteurization without steamis designed and constructed; and the overall temperature of the mushroom compost secondary fermenting tunnel is increased, so that the technical problem due to the introduction of the steam into the fermenting tunnel according to a universal adopted method in the industry is solved, and the good technical effects are realized.

Description

technical field [0001] The invention relates to the technical field of edible fungus production, in particular to a secondary fermentation tunnel device for edible fungus Pleurotus ostreatus compost. Background technique [0002] The medium for oyster mushroom cultivation needs to be fermented before it can be inoculated and cultivated. At present, the mushroom compost secondary fermentation tunnel has two functions in the actual mushroom compost secondary fermentation process: one is to eliminate all the sources of mushroom diseases and pests in the mushroom compost that affect the growth of mushrooms; The air is conditioned, and the mesophilic controlled fermentation is further carried out on the mushroom culture. Through the two-stage process of secondary fermentation, the mushroom compost is transformed into a mushroom compost that is highly selective for mushroom growth, that is, it is only suitable for the growth of mushrooms and not suitable for the growth and breedi...

Problems solved by technology

There are three disadvantages of this method: First, it needs to build a larger boiler, consume a lot of energy, release smoke and dust, pollute the environment, and support corresponding personnel, and increase labor costs; Humidity, especially in winter, especially for northern regions, where a large amount of condensed water will accumulate in the fermentation material; third, uneven steaming in a short period of time will kill beneficial fermentation microorganisms in a short period of time

This method is time-consuming and labor-intensive, polluting the environment
