Product Description
The production process of freeze-dried fruits and vegetables is mainly divided into raw material treatment, pre-cooling, freezing, freeze-drying, packaging and other links. Among them, raw material treatment is the first step in the production of freeze-dried fruits and vegetables, which must ensure that the raw materials are fresh, clean and pollution-free.
Precooling means that the raw material is first treated at low temperature during processing, so that its temperature is reduced to below 0℃. This process can effectively reduce the amount of condensing water during freezing and reduce the damage to raw materials during freezing.
Freezing is to freeze the raw materials in the cold storage below 0 ° C, so that the raw materials are quickly frozen, and the water is frozen inside the raw materials.
Freeze-drying is the heating of frozen raw materials, so that the water in it is directly converted from ice to gas, so as to achieve the purpose of drying. This process not only ensures the nutritional content, but also ensures the taste and quality of the raw materials.
Packaging is the packaging of freeze-dried fruits and vegetables, usually using composite film packaging to ensure the sealing and appearance quality of the product.
