Problems solved by technology

However, in the process, the cooling effect of the vacuum cooling method that only uses the material itself to lose water is very limited, especially for food materials with less water content, dense texture or waxy skin. Freezing below the eutectic point, insufficient freezing will result in shrinkage and deformation of the material during the freeze-drying process, and the quality of freeze-drying cannot be guaranteed
Moreover, the above-mentioned process is not only very difficult to realize with the help of existing separate equipment, but also makes the above-mentioned problems more prominent

Abstract

The invention relates to an integrated radiation vacuum freeze-dry device and method, further relates to a corresponding method, and belongs to the technical field of food devices. The freeze-dry device is characterized in that a vertical side bracket is fixed in a vacuum warehouse body, the side bracket extends out of heating shelves, and the heating shelves and a heat carrying agent heater form a heat exchange cycle system; an accommodating interval of a hanging material vehicle is formed between the two heating shelves on both sides, the hanging material vehicle comprises a vertical suspension which extends out of level trays which are positioned between the two adjacent level hollow heating shelves; spraying nozzles are distributed in the vacuum warehouse body, and are connected to a high pressure water conveying system through a pipeline. Through the adoption of the freeze-dry device disclosed by the invention, the low cost food freezing is realized, and all of the technological processes namely freezing and drying are completed once in the same device, so that the technological processes are simplified, the efficiency is obviously improved, and the freeze-dry device is suitable for various food materials, such as food materials which contain less water, are compact in texture or have wax coat surfaces.

Description

technical field [0001] The invention relates to a food freeze-drying equipment, in particular to an integrated radiation vacuum freeze-drying equipment, and also relates to a corresponding method, which belongs to the technical field of food equipment. Background technique [0002] Vacuum freeze-drying is an internationally recognized processing method for the production of high-quality, high-value-added dehydrated food. Material drying is carried out under low temperature and vacuum conditions, which can better retain the color, aroma, taste, shape and nutritional components of fresh materials. Add any preservatives, and the product is easy to preserve and circulate, has good instant dissolving and rehydration properties, and fully complies with the current development trend of "green, convenient, nutritious and safe" food. [0003] Vacuum freeze-drying equipment (freeze-drying machine) is the core production equipment of freeze-dried food processing. It usually has two str...
