Problems solved by technology

[0004] However, the traditional method of cultivating bean sprouts by releasing ethylene gas has the following problems: (1) the raw materials need to be placed in the room for a period of time before entering the cultivation room to wake up the seeds, and lime water is used to sterilize the soaking water
This kind of seed treatment process is complex, time-consuming and labor-intensive, and the lime water used for sterilization has not been purified and discharged randomly, which is not conducive to environmental protection; Inconsistencies in the cycle will affect the taste of food, and also affect the output and quality of the product, making it difficult to meet the requirements of large-scale production

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...

Abstract

The invention relates to a production process and a cultivation system for cultivating pollution-free bean sprouts by precisely controlling ethylene mixed gas. The production process comprises the following steps: washing raw materials with normal-temperature water; soaking and sterilizing the raw materials by using a natural plant bactericide; putting the sterilized raw materials into a mobile cultivation vehicle in a cultivation room, and preparing for cultivation; controlling the temperature and humidity of the cultivation room, and adjusting the concentration of oxygen, carbon dioxide and ethylene gas in the cultivation room; and forming products after 5-8 days of cultivation, and cleaning the products to finish the cultivation. The cultivation system comprises a bean sprout cultivation room, a central air conditioner, a gas release system, a detection system, a control system, an internal circulation axial flow fan, an external circulation axial flow fan and an air supply pipeline. The production process technology is mature, the working condition of the cultivation system is stable, the cultivation system is suitable for large-scale production, and the high-quality green pollution-free bean sprout products which are good in taste, good in appearance and stable in quality can be obtained through cultivation.

Description

technical field [0001] The invention relates to a production process and a cultivation system for precisely controlling ethylene mixed gas to cultivate pollution-free bean sprouts, belonging to the technical field of agricultural product processing. Background technique [0002] Sprouts grown from the seeds of soybeans, mung beans and other legumes, under suitable temperature conditions, using the nutrients stored in the seeds themselves, contain a large amount of high-quality protein, vitamin B, vitamin C, calcium, iron and other trace elements , rich in nutrition, crisp in taste, good in color and fragrance, it is an indispensable dish in the lives of residents. In order to ensure a sufficient supply of sprouts in the market, in the sprout cultivation process, including gibberellin, indole acetic acid, naphthyloxyacetic acid, paclobutrazol, 6-BA (6-benzyl adenine), KT-30 (chlorpyridine Plant growth regulators such as urea), amino acids, vitamins and citric acid, or combin...
