Abstract
The present invention provides an organic rice storage technology which includes the following steps: step 1, conducting a mechanical oven-drying and water reducing on fresh harvested organic rice with water content controlled at 10-14%; step 2, putting the water content controlled organic rice into a storage warehouse at a temperature of 20-25 DEG C; step 3, sealing the storage warehouse and exhausting air in the storage warehouse; step 4, aerating carbon dioxide into the storage warehouse using a gas cylinder; and step 5, conducting a sealing operation on the storage warehouse. The organic rice storage technology keeps fresh color and luster of the organic rice without getting moldy or generating vermin, and has better storage results.
Description
Technical field
The present invention relates to a kind of rice storage process, particularly relate to a kind of storage process of organic rice.
Background technology
Rice is due to outside endosperm is directly exposed to, and be subject to the impact of the extraneous environmental condition such as damp and hot, easy moisture absorption, causing heating rotten.Simultaneously rice can not suddenly cold and hot, and not easily hyperthermia drying or sunlight exposure, otherwise cause a large amount of quick-fried waist, produce more cracking rice, reduce rice quality.Therefore rice should select rational storage method, can save food like this, avoids waste.
Through the retrieval to existing document, the one that patent discloses of application number 201310015707.5 is put in storage, and moistening paddy is loaded warehouse; Precipitation, the mode of being ventilated by warehouse by the water content control of paddy at 15-16%; Low-temperature storage, is down to 18-25 DEG C by MW temperature, carries out low-temperature storage; And low temperature and high relative humidity processing.The technique of this invention stores water content and the temperature of paddy by controlled working, and low temperature and high relative humidity processing is carried out under this water content and temperature, not only fatty acid oxidation degree is lower, and it is slower in making rice process, to soak absorption speed at use paddy of the present invention.Application number 201410361630.1 also discloses a kind of storage method of rice, and it comprises the steps: the harvesting of a) paddy, carries out the plantation of paddy, and gather according to normal procedure after maturation according to the normal implantation methods of paddy; B) dry, first carry out the airing of outdoor sunshine under normal temperature to gathering in the paddy that comes up or carry out mechanical drying, reduce moisture content in paddy to moisture content below 12%; C) rice huller paddy, shells paddy in hulling machine; D) store in a warehouse, rice after shelling is loaded in woven bag, then one bag of bag superposition is in a row, be stacked on bracket by arranging woven bag more, airspace is formed between the woven bag that every two rows are stacked, but above storage method all only controls water content and the temperature of rice, the air regime stored accurately is not controlled.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of organic rice storage process, a kind of storage process of organic rice, described organic rice storage process is:
Step one, carries out mechanical drying precipitation by the fresh organic rice of harvesting, controls moisture at 10-14%;
Step 2, put into storage silo by controlling the organic rice of moisture well, control store storehouse temperature is at 20-25 DEG C;
Step 3, seals storage silo, is bled by the air in storage silo;
Step 4, uses dioxide bottle to pass into carbon dioxide in storage box;
Step 5, carries out seal operation by storage silo.
Pressure after bleeding in described step 3 is 0.5-0.8 atmospheric pressure.
After passing into carbon dioxide in described step 4, the concentration of carbon dioxide is 10-15%.
After passing into carbon dioxide in described step 4, oxygen content is 5-10%.
The material that in described step 5, seal operation uses is polyvinyl chloride film.
The present invention adopts above method, has following beneficial effect.Rice storage process prepared by the present invention can keep organic rice color and luster fresh, not mouldy, insect-free, has good result of use.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.The element described in one embodiment of the invention and feature can combine with the element shown in one or more other embodiment and feature.It should be noted that for purposes of clarity, in explanation, eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process.
