Embodiment Construction

[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but it is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be covered by the present invention. within the scope of protection.

[0016] The invention provides a method for producing wet corn whole meal, such as figure 1 As shown, the method includes the following steps:

[0017] (1) Corn pretreatment

[0018] Send corn kernels with moisture content ≤ 14% without mildew to the magnetic separator and stone remover through the bucket elevator to remove iron, stone and other sundries, and then pass through a 6-8 mesh fine vibrating screen and a 4-mesh coarse screen , sifting out sandy soil smaller than corn kernels and corn cob particles larger than corn kernels, etc., and the scre...

Abstract

The invention discloses a wet method for producing whole corn flour, comprising: step 1, puffing the corn through an airflow puffing technology after removing the impurities; step 2, partially crushing the puffed corn into big corn particles, mixing with the remaining puffed whole corn, and blanching with hot water; step 3, cooling the corn, adding with sodium percarbonate and soaking the corn; step 4: washing the corn with clean water to neutral, placing the corn in a fermentation tank, and adding with lactic acid bacteria to ferment; step 5: performing the solid and liquid separation after fermentation, washing the corn with water and grinding the corn into corn flour by wet method to obtain the whole corn flour after dehydrating and drying the slurry. The method can make all the components of the corn into flour without any by-products, the obtained corn flour retains all the nutrition of the corn and has good processing performance. The food processed with the corn flour has good taste, rich nutrition, and the method has simple production process and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of grain processing, and relates to a production method of corn flour, in particular to a method of using corn as a raw material, fermenting soaked corn with lactic acid bacteria, and wet grinding to produce whole corn flour. Background technique [0002] Corn is a widely grown crop that is not only high yielding but also rich in nutrients. A variety of products can be prepared by using different processing methods, which are applied in food, feed, brewing and other fields. The traditional method of processing corn into corn flour is to directly grind the corn kernels, or to grind the corn after peeling and degerming. Due to the low protein content in corn, corn flour is not easy to form dough. Therefore, the corn flour produced by these two processes has problems such as poor taste and poor processing performance. [0003] In response to the above problems, in order to improve the processing performance of corn flo...
