Product Introduction

Whole freeze dryer For blueberry

Blueberry has a short fruit period and needs to be preserved at low temperature. It has a typical problem of difficult preservation and transportation as well as inconvenient use. The current problem can be solved by fruit lyophilizer technology. Fruit freeze-drying machine is a mature application of vacuum freeze-drying machine in fruit freeze-drying processing technology.In modern life, food safety requires more standardization, health and nutrition. Fruit freeze-drying machine is widely used in the production and processing of freeze-dried apples, freeze-dried strawberries, freeze-dried durian, freeze-dried lemon and so on. Among them, blueberry is rich in anthocyanins and other nutrients, which has very high health value. The freeze dryer For blueberry processing technology of the whole blueberry is discussed below.

Most of the freeze-dried whole blueberries in the market can not meet the requirements, because in addition to the lack of blueberry freeze-drying technology, there is no high configuration freeze-drying machine, and the selected freeze-drying machine can not meet the process and technical requirements of the whole blueberry freeze-drying. The whole blueberry freeze-drying processing technology requires that the whole blueberry basically does not deform and change color after freeze-drying. The nutrients are basically maintained, and the rehydration is good.

The whole blueberry freeze-drying process is first pre frozen in a low-temperature freeze dryer. The pre freezing temperature is set to - 45 ~ - 50 ℃, and the pre freezing time is about 5 hours.Then the vacuum stage, primary drying stage and analytical drying stage are carried out. These three stages are the key to control. The vacuum of the freeze dryer needs to be fine tuned between 10 ~ 20Pa. At the same time, the partition of the freeze dryer carries out segmented slope temperature control, and the temperature control uniformity is ± 1 ℃. The slope data control is set according to the requirements of the engineer of FZG freeze dryer.Therefore, the whole blueberry freeze-drying processing technology needs to select the freeze-drying machine equipment that meets the process technology. If the whole blueberry is to be processed for freeze-drying, it is also necessary to have the whole blueberry freeze-drying process technology to ensure that the freeze-dried whole blueberry basically does not deform or change color, the nutrients are basically preserved, and the rehydration is good. Specific solutions can be provided by FZG lyophilizer engineers.
