Embodiment 1
[0044] A kind of cultivation system (such as figure 1 shown), including: sprout cultivation room, central air conditioner, gas release system, detection system, control system, external circulation axial flow fan, internal circulation axial flow fan, and air supply duct. The gas release system includes ethylene gas cylinders, carbon dioxide gas cylinders, and nitrogen gas cylinders; the number of sprout cultivation rooms is 1 to N, and N≥2.
[0045] The first sprout cultivation room is connected to the ethylene gas cylinder through the first air supply pipeline and solenoid valve switch 1, connected to the carbon dioxide gas cylinder through the second air supply pipeline and solenoid valve switch 2, and connected to the carbon dioxide gas cylinder through the third air supply pipeline and solenoid valve switch 3 is connected to the nitrogen gas cylinder, connected to the central air conditioner through the fourth air supply pipe and solenoid valve switch 4, and connected to t...
Embodiment 2
[0055] A production process for precisely controlling ethylene mixed gas to cultivate pollution-free bean sprouts, comprising the following steps:
[0056] (1) Cleaning: Wash the soybean raw material with normal temperature water to remove dead beans and impurities in the soybean raw material;
[0057] (2) Sterilization: Soak and sterilize soybean raw materials with natural plant fungicides. The concentration of natural plant fungicides is 0.03g / mL, the sterilization time is 2 hours, and the sterilization temperature is 20°C; the natural plant fungicides are tea poly A mixture of phenol, propolis, and sesame flower extract, wherein the mass ratio of tea polyphenols, propolis, and sesame flower extract is 1:1:1.
[0058] The preparation method of the sesame flower extract: adopt the alcohol extraction method, weigh the dry sesame flower powder raw material by weight, add 5 to 10 times the volume concentration of ethanol with a volume concentration of 95% of the raw material wei...
Embodiment 3
[0067] A production process for precisely controlling ethylene mixed gas to cultivate pollution-free bean sprouts, comprising the following steps:
[0068] (1) Cleaning: Wash the soybean raw material with normal temperature water to remove dead beans and impurities in the soybean raw material;
[0069] (2) Sterilization: use natural plant fungicides to soak and sterilize soybean raw materials, wherein the concentration of natural plant fungicides is 0.04g / mL, the sterilization time is 2h, and the sterilization temperature is 20°C; the natural plant fungicides are Neem The mixture of ethanol extract, propolis and sesame flower extract, the mass ratio of neem ethanol extract, propolis and sesame flower extract is 3:1:1.
[0070] The preparation method of sesame flower extract and neem fruit ethanol extract is the same: take dry neem fruit coarse powder or dry sesame pollen raw material by weight, add 95% ethanol with volume concentration 5 to 10 times of raw material weight, Re...
