Description

Technical Field

[0001] This utility model belongs to the field of wheat germ processing technology, and in particular relates to a device system for automated production of wheat germ. Background Technology

[0002] Wheat germ is a byproduct of wheat milling, comprising 1-2% of wheat grains. It is rich in protein, has high nutritional value, and possesses certain health benefits. Suitable for all population groups, wheat germ is not only rich in protein with a balanced amino acid profile but is also easily absorbed by the body, making it an excellent source of high-quality, complete protein. Used as a functional ingredient in food production, it can improve the structure and taste of certain foods. With a high market price, it is a popular gift and health supplement. Overall, this wheat germ product demonstrates excellent taste and promising market prospects.

[0003] Currently, wheat germ processing methods include small-batch processing using manually operated steamers or ovens. However, as market demand for this wheat germ product continues to increase, current production methods are gradually revealing significant limitations. Using electric ovens not only results in a very limited production capacity, making it difficult to meet the company's own needs and market sales requirements, but also incurs high labor costs, which to some extent restricts the large-scale development of the product.

[0004] In conclusion, in order to improve the production efficiency of wheat germ products, reduce labor costs, and increase product added value to meet the ever-growing needs of the company and the market, it is particularly necessary to develop a device system for automated production of wheat germ.

[0123] Application examples

[0124] The automated wheat production method using the apparatus system provided in the above embodiments and comparative examples includes the following steps:

[0125] (1) The wheat germ mixture is fed to the first screening device through the feeding device. After the first screening, it is dried by microwave sterilization and drying device under 15KW power until the moisture content is not higher than 5%. After cooling to 27℃, it is screened by the second screening device to obtain large germ flakes with an average particle size of 6mm and small germ flakes with an average particle size of 3mm.

[0126] (2) The small germ slices obtained in step (1) are pulverized using an ultra-fine pulverizing device, and then sieved three times using a third sieve device and magnetically separated to obtain germ powder.

[0127] A comprehensive analysis of the large germ slices and germ powder obtained using the apparatus systems provided in the above embodiments and comparative examples reveals the following points:

[0128] (1) Comprehensive analysis of Examples 1-3 shows that the device system provided by this utility model can simultaneously obtain large germ slices and germ powder, which can meet the application of wheat germ in different application scenarios; and can improve the production yield and efficiency of wheat germ, and reduce energy consumption costs.

[0129] (2) A comprehensive analysis of Examples 1, 4-6 and Comparative Example 1 shows that the first screening device is used for impurity removal;

[0130] If the first screening device is adjusted to a screen with progressively smaller aperture, the number of screen layers in the first screening device is reduced, or the first screening device is omitted, impurities in the wheat germ mixture cannot be effectively removed, thereby affecting the quality of the obtained germ powder or large germ flakes.

[0131] (3) Comprehensive analysis of Examples 1 and 7 shows that, compared with the vacuum drying oven, the microwave sterilization device used in this utility model has a sterilization function, further ensuring that the obtained products meet the national food safety standards and improving product quality;

[0132] (4) A comprehensive analysis of Examples 1 and 8 shows that omitting the ultrafine pulverizing device makes it impossible to obtain both large germ slices and germ powder at the same time, which makes the device system unable to meet the application needs of different application scenarios and reduces production efficiency.

[0133] In summary, the automated production device provided by this utility model can simultaneously produce large and small germ slices, meeting the application needs of wheat germ in different application scenarios; and can further improve the production yield and efficiency of wheat germ while reducing energy consumption costs.
