Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a flavor device and method for adding aromatherapy materials to pet freeze-dried food. Background Art

[0002] Pet freeze-dried flavoring device is a device used to make pet freeze-dried food. Its main function is to retain the original flavor and nutrients of the food through vacuum freeze-drying technology. This device usually includes a refrigeration system, a heating system, a vacuum system and a control system, which can effectively remove moisture from the food while maintaining its color, shape and taste.

[0003] The core of freeze-drying technology is to quickly freeze the food at low temperature, and then sublimate the water in a vacuum environment, so that it can directly change from solid to gas, thus avoiding the loss of nutrients that may occur in the traditional drying process. This technology can not only preserve the original flavor and nutrition of the food, but also significantly extend the shelf life of the food, allowing it to be stored at room temperature for several years without deterioration.

[0004] When the existing freeze-drying flavoring device is used, the target flavor is generally introduced into a negative pressure vacuum drying chamber through a pipeline, and the freeze-dried flavor is instantly atomized, resulting in low freeze-drying flavor efficiency and insufficient consumption of the target flavor medium.
