Description

Field of the invention

[0001] The present invention relates to a plant for processing food raw materials and, in particular, to a plant for spray drying food raw materials at low temperature, which discloses an innovative structure. State of the art

[0002] The types of nutrients required by the human body are very diverse. However, due to the hectic lifestyle of modern society, most people often fail to maintain a balanced and varied diet, leading to a deficiency of necessary nutrients. For this reason, many people opt for dietary supplements processed from food raw materials (including natural and non-natural raw materials) to supplement insufficient nutrients and health-promoting ingredients such as vitamins, minerals, and proteins, thus maintaining metabolism and healthy body. Currently, many dietary supplements on the market are produced in powder form for the advantage of simplified use and improved absorption by the body.

[0003] However, the current production of many nutritional supplements requires mixing food raw materials (such as proteins, enzymes) with water and other solvents (such as nutrient media). Therefore, when processing nutritional supplements into powder, high-temperature drying equipment is generally used to separate the water and solvents. However, since most food raw materials are not heat-resistant, practical application has shown that this method will gradually cause the nutrients in food raw materials to lose their activity and be destroyed, significantly reducing absorption efficiency and seriously impacting the quality of nutritional supplements. Some changes and breakthroughs are necessary. Object of the invention

[0004] The main objective of the present invention is to provide a plant for spray-drying food raw materials at low temperatures. The technical problem to be solved is how to develop a novel, more optimal and practical structure for a plant for spray-drying food raw materials at low temperatures.

[0005] To achieve the above object, a plant for spray-drying food raw materials at low temperature is provided, comprising: a drying chamber in the form of a container and comprising an upper end, a lower end, and an operating space; a spray element consisting of a receiving container and at least one nozzle, arranged at a location in the drying chamber and continuously connected thereto, the nozzle being oriented to point into the operating space of the drying chamber; a raw material conveyor, continuously connected to the receiving container of the spray element, for introducing the food raw material solution into the receiving container;A low-temperature air compressor is continuously connected to the receiving tank of the spray element, for compressing low-temperature outside air and introducing it into the receiving tank, so that the food raw material solution is introduced into the operating space of the drying chamber through the nozzle as a high-pressure gas in the form of a spray; a low-temperature nitrogen supply device is arranged on one side of the drying chamber and continuously connected thereto, for introducing low-temperature nitrogen into the operating space and thus keeping the interior of the drying chamber in a dry state at a low temperature, thereby achieving a drying effect when the food raw material solution is sprayed into the operating space to remove the water liquid and form a powdery food raw material;a powder collecting device arranged on one side of the drying chamber and continuously connected thereto for collecting and receiving the powdered food raw material therein;

[0006] Compared with the conventional technology, with the innovative and unique design and technical features of the present invention, the food raw material solution can be processed into powder in a low-temperature drying environment, so as to avoid destruction of the nutrients and activity of a food raw material by high temperatures, thereby ensuring the industrial applicability of improved absorption efficiency of the body and improved product quality.
