Problems solved by technology

Since the aluminum content of wheat is mainly concentrated in the cortex of the wheat, and the existing flour processing methods cannot thoroughly clean the cortex of the wheat, the aluminum content of the processed flour is still relatively high
The current flour processing method produces flour with a high rate of aluminum content greater than 10mg / kg, which cannot meet the requirements for export to the EU

Embodiment 1

[0015] The aluminum content of the hairy wheat is 400PPM, the aluminum content of the flour produced by the existing processing method is 27PPM, and the aluminum content of the flour produced by the processing method of the present invention is 4.2PPM.

Embodiment 2

[0017] The aluminum content of the hair wheat is 220PPM, the aluminum content of the flour produced by the existing processing method is 14PPM, and the aluminum content of the flour produced by the processing method of the present invention is 3.0PPM.

Embodiment 3

[0019] The aluminum content of the hair wheat is 76PPM, the aluminum content of the flour produced by the existing processing method is 7PPM, and the aluminum content of the flour produced by the processing method of the present invention is 2.2PPM.

[0020] At present, the flour produced by the processing method of the present invention has been inspected by Xiamen Entry-Exit Inspection and Quarantine Bureau in multiple batches, and the aluminum content is the highest at 4.5PPM and the lowest at 1.2PPM, completely exceeding the EU standard.

Abstract

The invention relates to a flour processing method, and in particular to a method for processing flour with low aluminum content. The method comprises the following steps: removing big impurities from crude wheat by using a grain cleaning machine; removing relatively big sands and stones by using a specific gravity stone remover; removing iron impurities by using a permanent magnetic roller; removing grass seeds by using a seed separator; threshing the wheat by using a horizontal wheat threshing machine; screening out impurities by using a vibrating screen; removing relatively small sands and stones by using the specific gravity stone remover; threshing the wheat by using the horizontal wheat threshing machine; screening out the impurities by using the vibrating screen; washing the wheat by using a strong wheat washer; watering for the first time (moistening the wheat); watering for the second time; rubbing the wheat by using a strong wheat rubbing machine; removing fine impurities by using a planar rotary screen to obtain pure wheat; and milling the wheat by using a milling machine to obtain the flour. The process of washing the wheat by using the strong wheat washer is added before the process of watering for the first time (moistening the wheat), and the process of threshing the wheat by using the horizontal wheat threshing machine after the process of watering for the second time is changed into the process of rubbing the wheat by using the strong wheat rubbing machine, so that the husk of the wheat can be removed relatively completely, the aluminum content of the flour can be effectively controlled, and relevant export standards can be met completely.

Description

technical field [0001] The invention relates to a flour processing method, in particular to a processing method of wheat flour with low aluminum content. Background technique [0002] Flour products are traditional bulk foods exported to the EU from Fujian Province, among which the export of flour products from Xiamen Port to Europe accounts for more than 90% of the province. At the end of 2009, the European Union began to implement "strengthening management measures" for Chinese flour products, stipulating that the specific sampling frequency is between 10% and 50%, and at the same time stipulating that the aluminum content in flour products should not exceed 10ppm (10mg / kg). Some EU countries such as the Czech Republic The limit standard even reaches 8.5ppm (8.5mg / kg). The flour products exported from Fujian were frequently notified by the European Union due to excessive aluminum content, resulting in a large drop in export volume, facing the crisis of being forced to wit...
