Preprocessing

The pre-treatment methods vary depending on the source and application of raw materials. For example, the pretreatment of fruits is to select, clean and cut into pieces, the vegetables need to be blanched, and the instant Congee needs to be cooked and platted.

Pre freezing

After raw material pretreatment, it is generally necessary to perform excellent pre freezing. This is because when there is a lot of moisture inside the material, if vacuum treatment is directly carried out, the gas dissolved in the water will escape due to the decrease in external pressure, forming bubbles, resulting in voids inside and on the surface of the raw material, affecting sensory quality.

quick-freeze

In order to solidify the moisture inside the material, quick freezing is usually required. The shorter the freezing time, the faster the material freezes, the smaller the internal crystallization, and the less mechanical damage to the material cells. Therefore, it is necessary to choose an appropriate freezing speed based on actual production.

vacuum drying

Vacuum drying is usually divided into two stages: sublimation drying and desorption drying. Sublimation drying mainly targets free water in materials; Analytical drying mainly involves removing adsorbed water that is strongly bound to solids. The vacuum degree, temperature, and plating thickness during the drying process directly affect the drying process and product quality.
