Problems solved by technology

Incomplete sterilization in industrial production of edible fungi leads to low yield, high production cost and high pressure on enterprises
It makes the production cost of the enterprise uncontrollable, unable to achieve annual stable production, difficult to meet the competitiveness of the enterprise in the market, and even one of the main reasons for the failure of industrialized production of edible fungi

Embodiment 1

[0022] In summer (June 1-September 1), start the autoclave and vacuumize twice in a row. When the pressure in the autoclave reaches -0.055Mpa for the first time, stop, and when the pressure returns to 0.010Mpa, start the second Vacuum for the first time to make the pressure reach -0.055Mpa; stop for sterilization at 100°C for 30 minutes, then raise the temperature to 122°C and stop for 60 minutes for sterilization; drainage: start from the end of the second vacuuming and the pressure returns to positive pressure, Until the end of the sterilization process; suffocation: close the drain valve and suffocate for 20 minutes; exhaust to reduce the pressure in the sterilizer to 0; the cooling chamber exits the autoclave. See image 3 .

Embodiment 2

[0023] Example 2: In winter (November 1-March 1), preheat to 30°C, let the cold air in the autoclave be exhausted, so as not to form too much condensed water due to the overcooling in the autoclave; Start the sterilizer; vacuumize twice in a row, stop when the pressure reaches -0.055Mpa for the first time, and when the pressure returns to 0.010Mpa, start vacuuming for the second time to make the pressure reach -0.055Mpa; directly raise the temperature to 122 Sterilize at ℃ for 90 minutes; drainage: from the end of the second vacuum pumping, the pressure returns to positive pressure, to the end of the sterilization process; suffocation: close the drain valve and suffocate for 20 minutes; exhaust to reduce the pressure in the sterilizer Reduced to 0; cooling chamber out of the kettle.

Embodiment 3

[0025] Example 3: In spring and autumn (March 1-June 1; September 1-November 1), preheat to 30°C, let the cold air in the autoclave be exhausted, so as not to cause damage to the autoclave Excessive condensed water is formed due to internal supercooling; start the autoclave; vacuumize twice in a row, stop when the pressure reaches -0.055Mpa for the first time, and start the second vacuumize when the pressure returns to 0.010Mpa, Make the pressure reach -0.055Mpa; heat up, stay at 100°C for 30 minutes for sterilization, then raise the temperature to 122°C and stay for 60 minutes; Drainage: from the end of the second vacuuming, the pressure returns to positive pressure, and the end of the sterilization process; Suffocation: close the drain valve, and suffocate for 20 minutes; exhaust to reduce the pressure in the autoclave to 0; exit the autoclave from the cooling chamber. See Figure 5 .

[0026] The following is the output table of bottled Flammulina velutipes industria...

Abstract

The invention relates to a sterilization process method for bottle-planted needle mushroom factory production applied to the technical field of edible mushroom factory production processes. In the bottle-planted needle mushroom factory production, after composts are adopted to be bottled, operation is carried out in a special sterilization device according to a special sterilization process flow. The method comprises the following steps: preheating: preheating a sterilization kettle in winter in advance, and discharging cold air in the sterilization kettle to avoid the inner part of the sterilization kettle being undercooled to cause excessive condensed water formation; starting the sterilization kettle; continuously vacuumizing for two times; heating sterilization: after heating to 100 DEG C, stopping to sterilize for 30 minutes, and then after heating to 122 DEG C again, stopping to sterilize for 60 minutes; dewatering: beginning from the second time of vacuumizing being finished and pressure being recovered to positive pressure, and ending until a sterilization schedule being over; sealed manufacturing: closing a drain valve for sealed manufacturing; exhausting: dropping the pressure in the sterilization kettle to zero; and cooling the sterilization kettle in a cooling chamber. The method is scientific in concept and simple in technique, can better meet the requirement of sterilization on the bottle-planted needle mushroom factory production, and improves the product yield.

Description

technical field [0001] The invention relates to an industrial production and sterilization process of bottle-grown Flammulina velutipes in the technical field of industrial production of edible fungi. Background technique [0002] The industrial production of edible fungi in my country started relatively late, and the cultivation technology of Flammulina velutipes is relatively mature for edible fungus varieties. The industrial production of Flammulina velutipes mainly has two production modes: bottle planting and bag planting, and factory production enterprises with a high degree of mechanization adopt the bottle planting system. Standardized production process of vase cultivation: ingredients - mixing - bottling - sterilization - cooling - inoculation - germination culture - fungus - budding - suppression - growth - harvesting - bottle digging. Sterilization is an important link in the industrial production of edible fungi. The purpose of sterilization is to use high tem...
