Description

Technical Field

[0001] The invention belongs to the field of oat grits production technology, in particular to a production technology of large oat seeds. Background Art

[0002] Oats, also known as wild oats, are an indispensable crop for regional agricultural production and for balancing the lives of urban and rural residents. Oats are nutritionally rich in protein, balanced in amino acids, and contain a comprehensive composition. They also contain soluble dietary fiber, unsaturated fatty acids, avenanthin, various vitamins, and minerals essential to the human body, making oat products possessing certain preventive and therapeutic benefits.

[0003] However, the traditional production process of oat grits involves manually sifting raw oat bran using winnowing baskets and bamboo sieves, washing the oats in a pool of water, and then steaming the bran-on oats in a pot over a wood fire using traditional methods. After drying in the sun, the cooked oats are ground to a constant weight using a steel mill, and the grits and bran are separated by hand. The fuzz is removed by hand through beating, and the process is repeated manually. This process is time-consuming and labor-intensive, and the separation of the grits and bran is not complete. This not only results in a large waste of raw materials, but also a grits yield of only about 57%, which is inefficient.

[0004] To address these issues, those skilled in the art have proposed a production process for large oat seeds to resolve the problems raised in the background art. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a production process for large oatmeal seeds to solve the problems of low production and processing efficiency of oatmeal grits in the prior art.

[0006] The production process of oat jelly includes the following steps:

[0007] Step 1: Raw material selection: high-quality, mold-free, and insect-free oats are selected as raw materials, and the oats are fed into an air sieve cleaner. After air separation, they are screened through a vibrating screen to remove large and light impurities, dust, unfilled, and broken oats. An electromagnet is installed at the outlet to remove small iron blocks and other impurities under the action of a strong magnet, obtaining the oats after the initial screening.

[0008] Step 2: Pretreatment: After air screening and vibration screening, the oats are sent to the blowing specific gravity stone remover through a conveyor. Under the action of wind and friction, impurities such as sand and side stones in the oats are removed to obtain the processed oats;

[0009] Step 3: Shelling the material: The pre-treated oats are conveyed to a fully automatic oat shelling machine through a conveyor for shelling to obtain naked oats;

[0010] Step 4: washing: The shelled oats are conveyed to a washing tank via a conveyor for washing to remove dust attached to the surface of the oats, as well as fine impurities and tiny sand particles, to obtain washed oats.

[0011] Step 5: steaming: the washed naked oats are transported to a grain steaming bed and steamed with high-temperature steam to obtain sterilized and matured naked oats;

[0012] Step six, drying treatment: the sterilized and matured naked oats are conveyed into a hot air drum dryer through a conveyor, and dried to a constant weight under the action of hot air to obtain dried naked oats;

[0013] Step 7, color sorting and sieving; the dried naked oats are fed into a color sorter through a conveyor to remove impurities such as grass seeds and hulled oats that have a different color from the naked oats, so as to obtain clean naked oats.

[0014] Step 8, delinting process: Clean naked oats are fed into a steel mill via a conveyor and ground. The oat delinting machine separates the fuzz attached to the outer layer of the naked oats, resulting in fuzz-free oat grits.

[0015] Step 9, Vibrating Screening: The fuzz-free oat grits are fed into a three-dimensional vibrating screen via a conveyor, where they are vibrated to separate uniform oat grits.

[0016] Step 10: Secondary air screening treatment: The oatmeal is sent to the air screening cleaner through a conveyor to further screen the oatmeal particles. At the same time, the oatmeal is removed by the air screening cleaner to obtain fine oatmeal with uniform particles and bright yellow color.

[0017] Step 11, making the finished product; the fine oatmeal without husk is divided into different specifications and packaged in different packaging methods to obtain the finished product.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention uses modern machinery for production and processing, which not only retains the natural food nutrients, but also effectively improves production efficiency, so that the various indicators of the finished oat grits meet the relevant standards, has the advantage of higher finished product quality, and forms an assembly line operation, which can save time and labor, and efficiently separate the seed skin, so that the grits production rate is as high as more than 95%.

[0020] 2. The present invention uses mechanical process impurity removal, high-temperature steaming and drying to not only efficiently remove husks, light impurities, etc. in oat grits, thereby improving the quality of the finished product, but also reduces the activity of oat enzymes, reduces enzymatic decomposition products, overcomes the generation of odor, and eliminates the waste of raw materials caused by manual processing, effectively reducing the time cost of production and improving production efficiency and quality.

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0023] Example:

[0024] As attached Figure 1 As shown:

[0025] The present invention provides a production process of large oat seeds, comprising the following steps:

[0026] Step 1: Raw material selection: select high-quality, mildew-free, and insect-free oats as raw materials to prevent inferior oats from causing a deterioration in the appearance and taste of the finished product. The oats are then fed into an air screen cleaner for air separation and then screened through a vibrating screen to remove large and light impurities, dust, unfilled, and broken oats. An electromagnet is installed at the outlet to remove small iron blocks and other impurities under the action of a strong magnet, obtaining the pre-screened oats to prevent excessive impurities from affecting the display of the finished product and to prevent impurities from affecting subsequent processes and the taste of the finished product.

[0027] Step 2: Pretreatment: After the wind screening and vibration screening, the oats are sent to the blowing specific gravity stone remover through a conveyor. Under the action of wind and friction, impurities such as sand and gravel in the oats are removed to obtain the processed oats. By using mechanical removal of sand and gravel, the efficiency of pretreatment screening can be improved, and the effect of removing impurities is better. The impurities are removed more cleanly. Compared with manual removal operations, it has the advantages of higher efficiency and better removal effect.

[0028] Step 3, material dehulling; the pre-treated oats are fed into a fully automatic oat dehulling machine via a conveyor to dehull, obtaining naked oats. By setting up a mechanized method to remove the outer shell of the oat material, the efficiency of oat dehulling can be improved.

[0029] Step 4, Washing: The hulled naked oats are conveyed into a washing tank for washing to remove dust, fine impurities, and tiny sand particles adhering to the surface of the naked oats. This washing process, combined with the pretreatment step, further removes impurities from the oats, improving the quality of oat production. It also removes the outer shell of the hulled naked oats, resulting in clean naked oats. The cleaned oats are then soaked in clean water for a period of time to soften them and facilitate subsequent processing. The soaking time can be determined based on the variety and quality of the oats.

[0030] Step 5, steaming treatment; the washed naked oats are conveyed to a steaming bed and steamed with high-temperature steam for 80 to 90 minutes to obtain sterilized and cooked naked oats. The cooked oats are then subjected to a steaming process to gelatinize the starch, increasing the viscosity and texture of the product. The steaming time and temperature can be adjusted according to the characteristics of the oats and the process requirements. The use of high-temperature steaming effectively shortens the cooking time, improves work efficiency, saves costs, and also has a sterilizing effect, reducing enzyme activity, reducing enzyme decomposition products, and overcoming the generation of off-flavors.

[0031] Step Six: Drying Process; The sterilized and cooked naked oats are conveyed into a hot air drum dryer and dried to constant weight under the action of hot air to obtain dried naked oats. Drying the cooked and gelatinized oats removes excess moisture, prevents product spoilage, and extends the shelf life of the finished oat product. At the same time, the mechanized drying process not only improves the drying efficiency of naked oats but also accurately ensures the quality of drying to constant weight, thereby improving the quality of the finished oat product.

[0032] Step 7: Color sorting and screening: The dried naked oats are conveyed to the color sorter through a conveyor to remove impurities such as grass seeds and hulled oats that have color differences from the naked oats, obtaining clean naked oats. The clean naked oats are then screened by the color sorter, which not only improves the screening efficiency, but also improves the screening accuracy and quality.

[0033] Step 8: Delinting: The clean naked oats are conveyed to a steel mill via a conveyor and ground into particles with a size of 1 to 3 mm. At the same time, the oats are passed through an oat delinting machine at a speed of 650 revolutions per minute to separate the fuzz attached to the outer layer of the naked oats, obtaining fuzz-free oat grits.

[0034] Step 9: Vibration screening: The fuzz-free oat grits are conveyed to a three-element vibrating screen via a conveyor, and the oat grits with a particle size of less than 1 mm and greater than 3 mm are separated by vibration, and the uniform oat grits with a particle size of about 2 to 3 mm are obtained, thereby ensuring the high quality of the finished product and having good aesthetics;

[0035] Step 10: Secondary air screening: uniform oat grits with a particle size of about 2 to 3 mm are conveyed to an air screening cleaner via a conveyor to further screen the oat grits to determine their particle size. At the same time, the air screening cleaner removes the husks and other impurities in the oat grits, resulting in fine oat grits with uniform particles and bright yellow color.

[0036] Step 11, making the finished product; the fine oatmeal without husk is divided into different specifications and packaged in different packaging methods to obtain the finished product.
