Abstract
A method for sterilizing the edible fungus includes such steps as loading the culture medium of edible fungus in bottles or bags, putting them in sterilizing pot, vacuumizing, filling high-temp steam to raise the temp to 121-126 deg.C for 50-70 min, vacuumizing for exhausting hot steam, filling clean air, and cooling. Its advantages are high effect, short time, and less consumption of steam.
Description
Technical field:
The present invention relates to the technical field of edible fungi sterilization, specifically the sterilizing methods of a kind of edible mushroom.
Background technology:
Edible fungi sterilization generally adopts autoclaving and normal-pressure sterilization at present.Autoclaving is directly to feed steam in autoclave, utilize steam that cold air in the pot is driven out of, this process need 2 hours, continue pressurization then and be warming up to 121 ℃, and kept 1.5～2 hours, carry out nature again and cool, the temperature in the autoclave is reduced to below 100 ℃, this temperature-fall period needs 0.5～1 hour again, accumulative total from heat up, insulation, cooling total run time 4～5 hours.During normal-pressure sterilization, sterilising temp reaches 100 ℃ in 2 hours, and keeps 8 hours～10 hours, carries out the nature cooling again, and its total run time is 12～16 hours.These two kinds of sterilizing methods, the too time-consuming expense material that all seems, and sterilization effect is general.
Summary of the invention:
The object of the present invention is to provide a kind of improved edible fungi sterilization method, it can overcome overlong time in the prior art, time-consuming expense material, some shortcomings that sterilization effect is general.
To achieve these goals, technical scheme of the present invention is: the sterilizing methods of a kind of edible mushroom, its feature comprise the steps: a, with culture medium of edible fungus pack into the bottle or the bag in, push in the autoclave then; B, unlatching vavuum pump vacuumize autoclave inside, when the force value in the autoclave reaches the setting value of pressure controller, close vavuum pump; C, start steam valve, an input vapours in the pot makes kettle temperature rise to 121-126 ℃, and keeps after 50-70 minute the steam off valve; D, startup vavuum pump are extracted vapours in the pot out discharge by force, close vavuum pump then, import pure air again in autoclave; E, unlatching autoclave are pulled out culture medium of edible fungus, and push the chilling room cooling, finish sterilization process.
Sterilization process of the present invention is as follows: open vavuum pump earlier, cold air in the autoclave is forced to extract out eliminating, close vavuum pump again, feed steam simultaneously, heat pressurization, make kettle temperature rise to 121 ℃～126 ℃, and kept 50～60 minutes, close steam, open vavuum pump again and extract vapours in the pot out eliminating by force, feed clean cold air, quicken to cool, when treating that kettle temperature is reduced to below 100 ℃, open autoclave, the cultivation strain bottle of having sterilized is pulled out, and push the chilling room cooling, finish the sterilization overall process.Its accumulative total sterilization time 2.5 hours～3 hours.This sterilizing methods has improved sterilizing efficiency, has reduced running time.Autoclaving was reduced to 2.5～3 hours from conventional 4～5 hours, and the steam use amount reduces 30%～40%, has saved the energy, has improved sterilization effect simultaneously.
The specific embodiment:
The invention will be further described below in conjunction with embodiment.
The sterilizing methods of a kind of edible mushroom of the present invention, its difference with the prior art is: described edible fungi sterilization method comprise the steps: a, with culture medium of edible fungus pack into the bottle or the bag in, push in the autoclave then; B, open vavuum pump, autoclave inside is vacuumized, when the force value in the autoclave reached the setting value of pressure controller, setting value was generally-0.02～-0.08Mpa, close vavuum pump; C, start steam valve, an input vapours in the pot makes kettle temperature rise to 121-126 ℃, and pressure remains on 0.1-0.15Mpa, and keeps after 50-70 minute the steam off valve; D, startup vavuum pump are extracted vapours in the pot out discharge by force, close vavuum pump then, with external pressure equate until the autoclave internal pressure that toward the interior input of autoclave pure air temperature is lower than 100 ℃ again; E, unlatching autoclave are pulled out culture medium of edible fungus, and push the chilling room cooling, finish sterilization process.
In force,, place in the corresponding basket, overlay in the go-cart, push in the lump in the autoclave, after equipment inspection is errorless, shut the autoclave door, start run switch, enter duty together with go-cart with culture medium of edible fungus pack into plastic bottle or polybag.Open vavuum pump then, begin autoclave inside is vacuumized.When the autoclave internal pressure reaches the setting value of pressure controller-0.055Mpa, close vavuum pump, stop to bleed.Simultaneously, start cap relief valve, in pot, import vapours.Begin the stroke of sterilizing, set the sterilising temp predetermined value: 121 ℃, treat that pressurized, heated to kettle temperature reaches 121 ℃ of predetermined values, when pressure is 0.15Mpa, begins to carry out sterilization process, utilize self-clocking, according to the size of autoclave and the product quantity of sterilization, make the temperature in the pot keep 121 ℃ of predetermined values, pressure 0.15Mpa, continue 50～60 minutes, after stop heating, finish sterilization, enter instroke.Start vavuum pump during exhaust, vapours in the pot discharged by force, treat that pot inner pressure reaches expectant control device setting value after, close vavuum pump.Simultaneously, an input pure air in the pot equates that with external pressure temperature is lower than 100 ℃ to the autoclave internal pressure again.Open the autoclave door, the car of filling cultigen bacterium bottle is pulled out, be pushed into chilling room, finish sterilization process.
