Abstract

The present invention discloses a degrease method using pine saw dust as the edible mushroom train element characterized in that: the big metal barrel with the diameter over a meter having a vent cap going through from outside, a curtain inside the big metal barrel on the vent cap spread with glass fiber bags, spreading pipe wood saw dust with 60% moisture evenly on the glass fiber bag 4-7 cm in thickness, transmitting vapor to the barrel through vent cap. When the pine wood saw dust steams, spread again till the barrel is full and seal it with an exhaust hole with the pine oil volatilizing and dissolving with vapor through the exhaust hole after 6 hours. The degrease method using pine saw dust as the edible mushroom train element is a good degreasing method with quick pine oil dissolving and volatilizing, complete degreasing and simple process.

Description

A kind of pine tree sawdust degreasing method as culture medium of edible fungus

Technical field: the present invention relates to a kind of technology, specifically a kind of pine tree sawdust degreasing method as culture medium of edible fungus.

Background technology: at present, pine tree sawdust generally has water-boiling method, method of piling and alkali bubble method as the degreasing method of culture medium of edible fungus.Water-boiling method is pine tree sawdust to be added water be placed in the pot and boil, and this method water is many, takes fuel, technology is loaded down with trivial details, degreasing is not thorough; Method of piling is to be deposited in together pine tree sawdust at one's discretion that wind rain shines, and makes its inner fermentation carry out the nature degreasing, and this degreasing method was about 6-12 month, and the time is long, and wind saws foam and exist everywhere, and not only raw material reduces to some extent, and contaminated environment; With the alkali bubble method that the limewash of 3-5% soaks sawdust, degreasing difficulty.

Summary of the invention: the objective of the invention is to, work out a kind of steam penetration power strong, decompose that the volatilization pine tar is fast, technology simple, degreasing is completely as the pine tree sawdust degreasing method of culture medium of edible fungus.Its technology contents is, a kind of pine tree sawdust degreasing method as culture medium of edible fungus, it is characterized in that, utilize one more than the one meter in diameter, the bottom is provided with one from leading to outward the big metal bucket of internal ventilation pipe, in big metal bucket, on the breather pipe, lay a curtain, on the curtain, be covered with one deck glass fiber bag, will contain the pine tree sawdust of 60% moisture content, be sprinkled upon thick 4-7 centimetre on the glass fiber bag equably, then, by breather pipe delivering vapor in the bucket, when pine tree sawdust begins to emit hot gas, seeing that the vapour place spreads pine tree sawdust again, repeat this process after barreled is expired, with the bung sealing, only stay an exhaust hole, after 6 hours again, pine tar in the pine tree sawdust is along with steam decomposes volatilization and discharges from exhaust hole.The present invention compares its advanced part and is with prior art, a kind of pine tree sawdust degreasing method as culture medium of edible fungus, have easy and simple to handle, technology simple, decompose that the volatilization pine tar is fast, degreasing characteristics completely, thereby existing water-boiling method, method of piling and alkali bubble method have been overcome in the pine tree sawdust skimming processes, existing some shortcomings part.

The specific embodiment: utilize one more than the one meter in diameter, the bottom is provided with one from leading to outward the big metal bucket of internal ventilation pipe, in big metal bucket, on the breather pipe, lay a curtain, on the curtain, be covered with one deck glass fiber bag, the pine tree sawdust that will contain 60% moisture content, be sprinkled upon thick 4-7 centimetre on the glass fiber bag equably, then, by a delivering vapor in the past bucket of breather pipe, when pine tree sawdust begins to emit hot gas, seeing that the vapour place spreads pine tree sawdust again, repeating this process after barreled is full, again bung is being sealed, only stay an exhaust hole, after 6 hours, the pine tar in the pine tree sawdust is along with steam decomposes volatilization and discharges from exhaust hole, at this moment, pine tree sawdust is finished degreasing, promptly can be used as the compost of edible mushroom, more than just constitute the present invention.

Claims

1. pine tree sawdust degreasing method as culture medium of edible fungus, it is characterized in that, utilize one more than the one meter in diameter, the bottom is provided with one from leading to outward the big metal bucket of internal ventilation pipe, in big metal bucket, on the breather pipe, lay a curtain, on the curtain, be covered with one deck glass fiber bag, the pine tree sawdust that will contain 60% moisture content, be sprinkled upon thick 4-7 centimetre on the glass fiber bag equably, then, by a delivering vapor in the past bucket of breather pipe, when pine tree sawdust begins to emit hot gas, seeing that the vapour place spreads pine tree sawdust again, repeating this process after barreled is full, again bung is being sealed, only stay an exhaust hole, after 6 hours, the pine tar in the pine tree sawdust is along with steam decomposes volatilization and discharges from exhaust hole.
