100-stage cleaning laminar flow inoculation under barotropic atmosphere during edible fungus industrial cultivation

Abstract

100-stage cleaning laminar flow inoculation under barotropic atmosphere during edible fungus industrial cultivation belongs to edible fungus production technology. The invention aims to solve the following problems: the existing open inoculation is inadvisable to be adopted under the conditions of plum rain seasons and high temperature and high humidity climate; poisonous residual quantity emerges when spatial standard sterilization is carried out in the inoculation environment; and the success rate of inoculation generally fluctuates from 97% to 99%. The invention is characterized in that fresh air enters into the top of the workshop under the pressure higher than the normal atmosphere pressure and is exhausted downwards after being efficiently filtered and purified by a 100-stage cleaning laminar flow cover; the inoculators, the inoculation machines and the fungus flask transfer cars are all arranged in 100-stage cleaning laminar flow from top to bottom; and the barotropic atmosphere of the 100-stage cleaning laminar flow from top to bottom is at least higher than 30Pa, the gas pressure in the cooling workshop and the corridor of the fungus culturing workshop. The invention preliminarily shows the following beneficial effects: inoculation can be carried out in due time at all seasons according to the production requirements; the problem of poisonous residual quantity emerging after standard sterilization is prevented; and the success rate of inoculation is stably as high as 99.7-99.9%.

Description

technical field [0001] The invention belongs to the production technology of edible fungi, in particular to a laminar flow inoculation method of positive pressure 100-level purification in the industrial cultivation of edible fungi. Background technique [0002] The open inoculation in the existing edible fungus cultivation, just as described in the 31-32 page in the first edition of China Agricultural Press "The Hundred Questions and Answers of Flammulina velutipes Production Key Technology" in January, 2006: the open inoculation in a narrow sense is Refers to the direct operation of inoculation in a relatively sterile and small environmental space (such as a sterile room). This inoculation method is used for shiitake mushrooms, enoki mushrooms and various rare edible fungi. Open inoculation mainly relies on the selection and judgment of the cleanliness of the environment and the control of skilled operating technical procedures to achieve a high success rate of inoculation...

AI Technical Summary

Problems solved by technology

(2) The cultivation bag must pass through the second buffer room before entering the inoculation room

Formaldehyde gas fumigation or the residual amount of Lysol solution after spraying will pose a hazard to the personnel who enter the sterilized inoculation environment and the edible fungi that enter the sterilized inoculation environment immediately
