Embodiment 1

[0025] The paddy is cleaned and husked to obtain high-quality brown rice, and the brown rice is put into a soaking tank whose soaking water temperature is 50° C. for 5 hours. After soaking, the brown rice is steamed in a steaming tank under normal pressure for 30 minutes at a steam temperature of 100°C; then dried quickly at a drying temperature of 55°C and a drying time of 75 minutes, and then dried for 50 minutes after the rapid drying is completed Slow drying, and then slow drying. The temperature of slow drying is 55°C, and the drying time is 50 minutes. Then cool to room temperature and enter the clean roughing warehouse. It can be packaged directly according to needs, and can also be vacuum-packed to obtain the finished parboiled rice after being processed in the rice milling section.

Embodiment 2

[0027] After the rice is cleaned and hulled, high-quality brown rice is obtained, and the brown rice is put into a soaking tank whose soaking water temperature is 55° C. for 4 hours. After soaking, the brown rice is steamed in a steaming tank under normal pressure for 25 minutes at a steam temperature of 100°C; then dried quickly at a drying temperature of 70°C and a drying time of 60 minutes, and then dried for 40 minutes after the rapid drying is completed Slow drying, and then slow drying, the slow drying temperature is 65°C, the drying time is 40min, and then cooled to room temperature into the clean rough room. It can be packaged directly according to needs, and can also be vacuum-packed to obtain the finished parboiled rice after being processed in the rice milling section.

Embodiment 3

[0029] The paddy is cleaned and hulled to obtain high-quality brown rice, and the brown rice is put into a soaking tank with a soaking water temperature of 60° C. for 3 hours. After soaking, the brown rice is steamed in a steaming tank under normal pressure for 20 minutes, and the steam temperature is 100°C; then it is dried, and the drying temperature is 85°C, and the drying time is 45 minutes. Slow drying, and then slow drying, the temperature of slow drying is 75°C, and the drying time is 30 minutes, then cool to room temperature and enter the clean roughing warehouse. It can be packaged directly according to needs, and can also be vacuum-packed to obtain the finished parboiled rice after being processed in the rice milling section.

[0030] In combination with Examples 1 to 3, the present invention uses brown rice instead of paddy to increase the nutritional content of parboiled rice. Here is a comparison of nutrients:

[0031] (1) Ordinary rice:

[0032] Protein conten...

Abstract

The invention discloses a novel environmentally-friendly preboiled rice preparation method which produces preboiled rice by carrying out hydrothermal treatment on brown rice. The novel environmentally-friendly preboiled rice preparation method is characterized by comprising the following preparation steps: cleaning and rice hulling; soaking; steaming; drying, cooling and grinding. The novel environmentally-friendly preboiled rice preparation method has the purposes that according to the method for carrying out hydrothermal treatment on the brown rice serving as a raw material, unhusked rice is replaced for production of the preboiled rice; by the use of the preparation method for producing the preboiled rice, effective use of energy in production can be increased, the production technological process and technological conditions can be simplified, and the processing period is short; furthermore, the nutritional quality of the preboiled rice is improved, the color and the smell of the preboiled rice are improved, and the use quality of the preboiled rice is improved.

Description

technical field [0001] The invention relates to the technical field of parboiled rice processing, in particular to a novel and environmentally friendly method for preparing parboiled rice. Background technique [0002] With the improvement of people's living standards, people's awareness of health and nutritional needs continue to increase. Daily consumption is no longer limited to ordinary rice, but to pursue more nutritious nutritionally fortified rice. Parboiled rice is a healthy food with high nutritional value, which meets people's pursuit of nutrition and health with the improvement of living standards. [0003] Parboiled rice refers to the cleaned rice that undergoes hydrothermal treatment such as soaking, steaming, drying and cooling, and then is finally processed into finished products through husking, rice milling and other processes. Through hydrothermal treatment, the water-soluble nutrients in the cortex and embryo are transferred to the endosperm to achieve th...
