[0002] With the public's attention to health and sustainable development, plant-based foods have risen in recent years. In particular, oat-based plant-based beverages not only have a smooth and full taste and balanced nutrition, but oats are also rich in unsaturated fatty acids and β-glucan and contain no cholesterol, making them ideal foods for people who pay attention to healthy eating.

[0003] At present, the production method of oat pulp mainly includes: baking and ripening oat grains, crushing the ripened oat grains to obtain oat flour, then enzymolyzing and inactivating the oat flour in sequence, and then centrifuging and removing the inactivated pulp to obtain oat pulp. This method has a high production cost, and in order to ensure the taste of the oat pulp, the oat pulp needs to be centrifuged and removed, and the centrifugal removal will remove a large amount of nutrients (such as protein, dietary fiber, etc.), so the nutrients of this method will be greatly reduced.

[0004] The inventor directly processes raw oat grains, and realizes online continuous production of oat pulp from raw oat grains through washing, steaming, grinding, enzymolysis / enzyme inactivation, and microfluidization treatment. There is no need to bake and mature the raw oat grains or grind them into oat flour to produce oat pulp, and there is no need for centrifugal deslagging treatment. The original flavor of oats can be better maintained and the original nutrients in oats can be completely retained. To this end, the inventor designed a new oat pulp production device, namely the continuous production device of oat pulp of the present application. Utility Model Content

The temporary storage tank circulation branch pipe control valve 471 and the temporary storage tank discharge branch pipe control valve 461 have an open state and a closed state. When the particle size of the material in the temporary storage tank 42 reaches the set value, the temporary storage tank circulation branch pipe control valve 471 is in a closed state and the temporary storage tank discharge branch pipe control valve 461 is in an open state; when the particle size of the material in the temporary storage tank 42 does not reach the set value, the temporary storage tank circulation branch pipe control valve 471 is in an open state and the temporary storage tank discharge branch pipe control valve 461 is in a closed state, so that the material enters the refining pump 41 for re-refining, thereby ensuring that the slurry particle size reaches the set value, which is conducive to the stable progress of subsequent processes.

[0051] A weighing sensor 424 is installed at the bottom of the temporary storage tank 42, and a washer 421, a temporary storage tank hot water control valve 422 and a temporary storage tank cleaning liquid control valve 423 are installed on the upper part.

Along the flow direction of the slurry, the heat exchange mechanism 45 is located at the front end of the refining pump 41. The refining temperature is controlled to be between 55 and 65°C by a heat exchanger with both heating and cooling functions. First, it prevents the high-temperature gelatinization of the refining material, or the low-temperature viscosity is too high to be convenient for transportation, and second, it is convenient to meet the subsequent enzymatic hydrolysis-related temperature requirements. The cooling and heating of the heat exchanger can be achieved by introducing a refrigerant and a heat medium.

[0053] The cooked oat grains enter the refining pump 41 through the regulating valve 351 of the discharge pipe of the cooking equipment for online refining, and enter the temporary storage tank 42, and the materials in the temporary storage tank 42 are refined online with the refining pump 41 through the circulation pump 44, and the online temperature is controlled through the heat exchange mechanism 45. Preferably, after all the materials in the cooking equipment 31 enter the refining equipment, the online refining is continued for 20 to 30 minutes.

[0055] The micro-jet unit 7 comprises a low-pressure micro-jet unit (micro-jet homogenizer) having a low-pressure micro-jet cavity 71 and a high-pressure micro-jet unit (micro-jet homogenizer) having a high-pressure micro-jet cavity 72 which are sequentially arranged along the flow direction of the material.

[0056] The secondary cooling unit 8 can refer to the prior art.

[0057] The temporary storage unit 9 should be equipped with a cooling jacket and a heat preservation jacket to facilitate the control of the material temperature to be maintained at ≤6°C to ensure that the material will not deteriorate during the temporary storage process.

[0058] The above-mentioned oat pulp production device directly uses raw oat grains for processing, which can not only well preserve the original oat flavor, but also greatly reduce the production cost. Compared with the traditional roasted cooked oat grains, it can save about 1.5 to 2 yuan / kg; compared with the traditional use of oat flour to produce oat pulp, it can save about 2.0 to 2.5 yuan / kg. In addition, the device can not only realize the continuous production of oat pulp, but also produce oat pulp with better particle size and taste, and completely retain the nutrients contained in the oats themselves.
