Embodiment 1

[0020] Such as figure 1 Shown, a kind of mushroom wood powder rapid sterilization device comprises a sterilizing kettle and a cooling and lowering device; The feed inlet 3 at the upper end of the sterilization kettle body 1, the discharge outlet 4 arranged at the lower end of the sterilization kettle body 1, and the stirring 5 arranged in the sterilization kettle body 1, the upper end of the sterilization kettle body 1 is provided with an air outlet A pipeline 11, the other end of the outlet pipeline 11 communicates with the cooling device, the outlet valve 12 is arranged on the outlet pipeline 11, and the steam inlet 2 communicates with an external steam pipeline.

[0021] The sterilizer body 1 is provided with a pressure gauge 6 and a thermometer 7; the cooling device includes a condenser 8, a vacuum unit 9 and a cooling tower 10; the vacuum unit 9 and the cooling tower 10 communicate with the condenser 8 ; The sterilizing kettle body 1 is provided with a sterile air inlet...

Embodiment 2

[0024] A kind of rapid sterilization device of mushroom wood powder is the same as embodiment 1, the difference lies in the sterilization method of the rapid sterilization device of mushroom wood powder. During the sterilization of shiitake mushroom wood powder, first close the outlet valve 12, the inlet valve 18 and the discharge valve 20, and open the condenser 8, the vacuum unit 9, the cooling tower 10. Send the mushroom wood powder into the sterilizing kettle body 1 from the feed port 3, close the feed port 3, start the stirring 5, the stirring speed is 20 rpm, and input the steam in the steam pipeline from the steam inlet 2, Observe the pressure gauge 6 and the thermometer 7, keep the pressure at 0.1-0.5MPa, and sterilize at 121-127°C for 3 hours. After the sterilization is finished, stop feeding the steam, open the outlet valve 12 and the inlet valve 18, the vacuum is 0.1-0.3MPa, the temperature in the sterilizing kettle body 1 drops to 17°C, stop cooling, and the coolin...

Embodiment 3

[0026] A kind of rapid sterilization device of mushroom wood powder is the same as embodiment 1, the difference lies in the sterilization method of the rapid sterilization device of mushroom wood powder. During the sterilization of shiitake mushroom wood powder, first close the outlet valve 12, the inlet valve 18 and the discharge valve 20, and open the condenser 8, the vacuum unit 9, the cooling tower 10. Send the mushroom wood powder into the sterilizing kettle body 1 from the feed port 3, close the feed port 3, start the stirring 5, the stirring speed is 40 rpm, and input the steam in the steam pipeline from the steam inlet 2, Observe the pressure gauge 6 and the thermometer 7, the pressure is 0.3-0.8MPa, and the temperature is 136-140°C for 2 hours of sterilization. After the sterilization is finished, stop feeding the steam, open the outlet valve 12 and the inlet valve 18, the vacuum is 0.2-0.4MPa, the temperature in the sterilizing kettle body 1 drops to 25°C, stop cooli...

Abstract

The invention relates to a mushroom wood powder fast sterilization device and sterilization method. The mushroom wood powder fast sterilization device comprises a sterilization kettle and a cooling temperature reducing device, wherein the sterilization kettle comprises a sterilization kettle body, a steam air inlet formed in the sterilization kettle body, a feeding opening formed in the upper end of the sterilization kettle body, a discharging opening formed in the lower end of the sterilization kettle body and a stirrer arranged in the sterilization kettle body; an air outlet pipeline is arranged on the sterilization kettle body; the other end of the air outlet pipeline is communicated with the cooling temperature reducing device; an air outlet valve is arranged on the air outlet pipeline; the steam air inlet is communicated with an outside steam pipeline. The mushroom wood powder fast sterilization device has the advantages that the structure is simple; the sterilization kettle body is pressurized through steam; the mushroom wood powder is directly heated by steam; the temperature and the pressure are high; the effect of fast and thorough sterilization is achieved. The sterilization method is simple, can be easily understood, and can be easily mastered, the technical requirements are low, the sterilization speed is high, the temperature reducing time is short, and the sterilization effect is good.

Description

technical field [0001] The invention relates to the technical field of shiitake mushroom production, in particular to a rapid sterilization device and a sterilization method for shiitake mushroom wood powder. Background technique [0002] The current compost for shiitake mushrooms generally goes through a high-temperature sterilization step before inoculation, and after the compost is sterilized, it must be cooled to normal temperature before inoculation. Chinese patent 201410179537.9 discloses a method for cultivating shiitake mushrooms at high temperature in summer. The step of sterilizing the compost is to stack the loaded edible mushroom bags vertically up and down in an atmospheric pressure sterilization stove for sterilization, and the normal pressure sterilizing There are air passages in the middle and around the bacterial focus; when the temperature in the atmospheric pressure sterilization focus reaches 95-100°C, maintain the sterilization for 20-24 hours; the cooli...
