Problems solved by technology

[0003] In the actual production process, the rate of broken rice in rice obtained by rice processing technology accounts for 15-30%. Due to the following two reasons, the rate of broken rice will increase: the first is various treatments before rice processing, including rice The state of harvesting, during the process of threshing, tumbling, loading and unloading machine transportation, etc., the rice is crushed by mechanical impact; the second is the process performance of rice processing machinery and equipment and operation management level, etc.

Embodiment 1

[0020] Embodiment 1: rice processing technology, comprises the following steps:

[0021] Step 1. Impurity removal: Put the harvested rice into the impurity remover to remove impurities, such as straw fragments and other light and large pieces of impurities, and then spread the rice in the drying room;

[0022] Step 2. Dehumidification: Use hot air at 40°C to dry the rice spread in the drying room several times. The thickness of the spread is 1.2cm. After drying for 60 minutes, take it out and turn it, and then dry it after cooling for 10 minutes until the rice contains water. The rate is 12 to 14%, and the paddy is cooled to room temperature;

[0023] Step 3, one-time rice milling: put the rice cooled to room temperature into the rice mill to remove the chaff, so that the hulling rate is between 60% and 80%, and the semi-finished product is obtained;

[0024] Step 4. Wetting: Atomize the semi-finished product so that water mist adheres to the surface of the semi-finished prod...

Embodiment 2

[0029] Embodiment 2: rice processing technology, comprises the following steps:

[0030] Step 1. Impurity removal: Put the harvested rice into the impurity remover to remove impurities, such as straw fragments and other light and large pieces of impurities, and then spread the rice in the drying room;

[0031] Step 2. Dehumidification: Use hot air at 35°C to dry the rice spread in the drying room for several times. The thickness of the spread is 0.8cm. After drying for 50 minutes, take it out and turn it, and then dry it after cooling for 10 minutes until the rice contains water. The rate is 12 to 14%, and the paddy is cooled to room temperature;

[0032] Step 3, one-time rice milling: put the rice cooled to room temperature into the rice mill to remove the chaff, so that the hulling rate is between 60% and 80%, and the semi-finished product is obtained;

[0033] Step 4. Wetting: Atomize the semi-finished product so that water mist adheres to the surface of the semi-finished ...

Embodiment 3

[0038] Embodiment 3: rice processing technology, comprises the following steps:

[0039] Step 1. Impurity removal: Put the harvested rice into the impurity remover to remove impurities, such as straw fragments and other light and large pieces of impurities, and then spread the rice in the drying room;

[0040] Step 2. Dehumidification: Use hot air at 40°C to dry the rice spread in the drying room for several times. The thickness of the spread is 1.0cm. After drying for 55 minutes, take it out and turn it, and then dry it after cooling for 10 minutes until the rice contains water. The rate is 12 to 14%, and the paddy is cooled to room temperature;

[0041] Step 3, one-time rice milling: Put the rice cooled to room temperature into the rice mill to remove the chaff, so that the hulling rate is between 60% and 80%, and the semi-finished product is obtained;

[0042] Step 4. Wetting: Atomize the semi-finished product so that water mist adheres to the surface of the semi-finished ...

Abstract

The invention discloses a rice process in the technical field of rice processing. The rice process comprises the steps of: impurity removal; dehumidification: paddies are paved in a drying room for drying by a hot air drying method to reach the paddy water content of 12-14%, and the hot air temperature is 35-45 DEG C; primary rice milling: the unshelling rate reaches 60-80%; attachment of water mist on the surfaces of semi-finished products by an atomization method; drying of the semi-finished products by cold air to reach the semi-finished product water content of 12-14%; secondary rice milling; polishing; and color sorting and classification. The paddies are cooled before being suffered from a mechanical effect in each link; compared with traditional airing and direct once high-temperature drying, the dehumdification process alleviates the effect of taking away water in the paddies, and is uniform in heating; compared with a traditional process, the rice process combines wetting and drying procedures, adds the wetting and drying, after wetting, steps, and uses secondary rice milling for largely reducing the rice milling rate; and the same one batch of paddies machined by the method reaches the rice milling rate of below 8%.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice processing technology. Background technique [0002] Rice is one of the most commonly eaten staple foods. Rice processing in a broad sense refers to the comprehensive processing process from rice husking to polished rice products. The rice processing process basically includes impurity removal, rice milling, polishing, color sorting, grading and packaging. [0003] In the actual production process, the rate of broken rice in rice obtained by rice processing technology accounts for 15-30%. Due to the following two reasons, the rate of broken rice will increase: the first is various treatments before rice processing, including rice The state of harvesting, during the process of threshing, tumbling, loading and unloading machine transportation, the rice is crushed by mechanical impact; the second is the technical performance and operation management level of rice pr...
