Universal drying equipment and method for extracting concentrates

Abstract

The invention provides a universal drying equipment and method for extracting concentrates of various animals and plants and relates to the technical field of food and medicine drying. The drying equipment is composed of an interlayer compartment body, a drying storehouse, a heat exchanging shelf, a heating and cooling system, a vacuum system, a test probe and a control system. The drying method comprises the four steps that 1, the concentrates are extracted, loaded into a disc and conveyed into the storehouse; 2, an expansion body is formed and shaped; 3, the expansion body is dried; and 4, the dried object is cooled and conveyed out of the storehouse. The universal drying equipment and method for extracting the concentrates dry the expansion body (a porous expansion structural body) formed by the extracted concentrates instead of directly drying the extracted concentrates, so that the purpose of quick drying at the low temperature can be achieved, and meanwhile the color, fragrance, property and flavor of original concentrates can be maintained. The universal drying equipment and method are suitable for drying the extracted concentrates of the various animals and plants, and the problems that a lot of concentrates are difficult to dry, or cannot be dried or is low in drying efficiency, or the property of the dried object is changed in the common drying process are solved.

Description

technical field [0001] The invention relates to the technical field of food and medicine drying, in particular to a general equipment and drying method for drying animal or plant extract concentrates. Background technique [0002] For the convenience of carrying and eating, it is necessary to extract, separate, concentrate, dry and package the nutritional components and / or medicinal components of animals or plants. Because the extract concentrate usually also contains viscous components such as oil, mucus, polysaccharides, resins, gums, etc., these viscous components have large thixotropy and poor air permeability, and they need to be dried at high temperature for a long time to achieve the purpose of evaporating and removing the solvent, and even cannot be dried. It can be made into liquid drink or oral solution. However, high-temperature and long-time drying, especially in the later stage of the drying process, will gradually increase the content of nutrients or medicinal...

Problems solved by technology

Although freeze drying has wide applicability, it has long drying time, high equipment price, high energy consumption, and low efficiency; although spray drying is fast, it has high temperature, easy to agglomerate and stick to the wall of the device, uneven drying, and large product loss. , not suitable for drying of heat-sensitive and viscous concentrates; traditional hot air drying, vacuum heating drying and radiation drying, although the price of the equipment is low or moderate, and the applicability is wide, but the temperature is high, the temperature difference fluctuates greatly, and the drying time Long, low efficiency, not suitable for drying heat-sensitive and viscous concentrates
