A kind of preparation method of mushroom stick

Abstract

The invention relates to a method for preparing mushroom sticks. The method comprises the following steps of culture compost preparing, culture compost sterilizing, cooling, inoculating and bagging, stick spawn running culture, stick coloring management and mushroom bud pressing fruiting, harvesting and flushing management. According to the method for preparing the mushroom sticks, bags are not prone to being damaged, sterilization is achieved thoroughly, the sterilizing and cooling time is short, strains are distributed evenly, and the fruiting period is short.

Description

Technical field [0001] The invention relates to the technical field of production of edible fungi, in particular to a method for preparing mushroom sticks. Background technique [0002] The traditional production process of shiitake mushrooms is: using polyethylene plastic film to prepare cultivation bags→preparation→culture material preparation→bagging→normal pressure sterilization to make material rods→cooling→perforating inoculation with bacteria→mycelium cultivation→ Fruiting management→harvesting. The texture of the uncured culture material is hard and easy to fry the culture bag, and the loss is serious, and the uncured culture material produces mushrooms more slowly, usually 5-6 months, and the time is longer; the traditional sterilization method is 100℃ Normal pressure sterilization, the sterilization time is 30 hours, the time is longer, the sterilization is not complete, and the bag expansion rate of 3%-15% is often seen; the traditional cooling process is natural cool...

AI Technical Summary

Problems solved by technology

The texture of the unripe compost is hard and easy to damage the culture bag, resulting in serious loss, and the fruiting of the unripe compost is slow, generally 5-6 months, which takes a long time; the traditional sterilization method is 100°C Atmospheric pressure sterilization, the sterilization time is 30 hours, the time is long, the sterilization is not complete, and the bag expansion rate of 3%-15% often occurs; the traditional cooling process is natural cooling, and the cooling time is as long as 20-30 Hours, affecting production efficiency; and inoculation in the later stage of inoculation, resulting in uneven distribution of bacteria, and for the later bacteria cultivation process, it enters the air again, causing secondary pollution, and the bacteria cultivation takes a long time Up to 3-4 months, the necrosis rate is as high as 10-20%, which greatly reduces the output of shiitake mushrooms

[0003] The Chinese patent application number 201410179537.9 discloses a summer high temperature shiitake mushroom cultivation method with good cooling and moisturizing effects, high mushroom quality and saving a lot of manpower and water and electricity resources, but this shiitake mushroom cultivation method cannot solve the problem of mushroom stick cultivation management process The sterilization time in the process is long, the puncture in the sterilizing process is labor-intensive, and the process is complicated. After the puncture, the heat generated by the bacterium stick itself will easily lead to a high risk of burning bacteria, the sterilizing cycle is long, and it is easy to sterilize the material stick. Problems such as bag expansion will affect the output and quality in the slightest, and lead to bad rods and failure in the severe case.
