[0013]2. Most of the existing seed germination techniques are based on experience or test results, and the seeds are germinated by soaking in water for a long time, which is easier for the growth of microorganisms in the seeds to produce Rancid, stinky and other peculiar smells are not conducive to large-scale and large-scale production

Embodiment 1

[0031] In this embodiment, the germination of brown rice is taken as an example.

[0032] 1. Preliminary preparation of plant seeds and determination of germination temperature

[0033] To ensure that each grain of brown rice can germinate, you should buy whole brown rice. Intact brown rice should contain rice bran layer, germ, and endosperm, and the smooth and translucent bran layer is intact brown rice. In addition, the rice used for processing brown rice should confirm that it has not been subjected to high temperature treatment during the drying process to avoid inactivation.

[0034] Determination of brown rice germination temperature: According to the variety of brown rice, germination time, quality of germinated rice, etc., germination is carried out under experimental conditions. The method is as follows: using a constant temperature water bath, the amount of brown rice put in is less than 50g / l of water, continuously soaking and germinating at different temperatures...

Embodiment 2

[0045] In this embodiment, wheat germination is taken as an example, the main steps are the same as in Example 1, and the specific parameter steps are as follows.

[0046] 1. Cleaning and soaking

[0047] Filling the selected wheat into the sprouter, washing and soaking with water, the water temperature during soaking is 17-19°C, so that the moisture content of the washed and soaked wheat is 40%-45%.

[0048] 2. Germination

[0049] The germination temperature is controlled at 15-19°C, the water content is 40%-45%, water is injected every 4 hours, the water injection temperature is 10-24°C, and vacuuming and vacuuming are performed every 4 hours until germination The vacuum can be released when a pressure of ≤-0.05Mpa (gauge pressure) is generated in the container.

Embodiment 3

[0051] In this embodiment, soybean germination is taken as an example. The main steps are the same as in Example 1, and the specific parameters are as follows.

[0052] 1. Cleaning and soaking

[0053] Fill the selected soybeans into the germination device, wash and soak them with water, and the soaking temperature is about 25°C, so that the moisture content of soybeans reaches about 65%, and the germination temperature of soybeans is 25-30°C.

[0054] 2. Germination

[0055] The germination temperature is controlled at 25-30°C, and the water content is controlled at more than 65%. Water is injected every 4 hours, and the water injection temperature is 20-35°C. At the same time, vacuuming and vacuuming are performed every 4 hours, and the vacuum is pumped to the germination container. The vacuum can be released when a pressure of ≤-0.05Mpa (gauge pressure) is generated inside.

Abstract

The inventing relates to a germination technology of plant seed, in particular to an industrialized germination production technology of crop seeds, such as rice sprout, malt and the like, and a germination technology before sowing plant seed. A wet breathing germination technology is performed by adopting water injection and drainage, a dry breathing germination technology and a double breathinggermination technology are performed by adopting vacuum pumping, by adopting the properties of water, such as high thermal capacity, shapelessness, low viscosity and easy flowing, water injection anddrainage and vacuum pumping operation processes are performed to plant seeds in a container through water temperature controlling, to enable the plant seeds to obtain moisture, temperature and fresh air required by germination, to exhaust the waste gas released by the seeds during the germination process, and to rapidly and efficiently accomplish the seed germination process. The technology has the advantages that the germination cycle is short, the operation is simple, the production costs of dry and wet breathing methods are extremely low, the germination percentage can be larger than 95 percent under the conditions that no germinator and nutrient solution are added, and the technology is suitable for the large-scale industrialized production.

Description

Technical field: [0001] The present invention relates to a germination process of plant seeds, in particular to an industrial germination process of crop seeds such as grain buds, rice germs, and malt, and relates to agricultural production (seed germination before plant sowing), rice processing (brown rice germination), beer Technical areas such as production and food processing. Background technique: [0002] The germination of plant seeds is originally a natural phenomenon in nature. Most of the plant seeds can germinate naturally under suitable conditions such as temperature, moisture, and air. The quality, time, and speed of germination depend entirely on temperature, moisture, etc. , air and other natural conditions. Moisture is an absolute must for seeds to germinate. With water, enzymes can be active, nutrients stored in seeds can be hydrolyzed to produce effects, and cells can expand and elongate. Generally, the water absorption required for seed germination exce...
