[0002] In the production process of goat milk powder, the preservation of fresh milk is crucial. Fresh goat milk needs to be stored at a suitable temperature to ensure its quality and nutrient content are not destroyed, and to avoid microbial growth leading to deterioration.

[0003] Traditional fresh milk preservation devices have many shortcomings in terms of insulation performance. Common single-layer insulation materials such as ordinary foam or simple heat insulation cotton have limited insulation effect, making it difficult to effectively block external heat or internal cold loss.

In heating storage mode, single-layer insulation materials cannot maintain a warm environment in the tank, and heat is easily lost, requiring the heating system to run at high load, resulting in energy waste and difficulty in precise temperature control. To solve the above problems, a fresh milk preservation device capable of switching cold and hot storage is proposed. CONTENT OF THE INVENTION

The heat insulation material layer 201 serves as the inner layer, which first hinders heat conduction by virtue of its low thermal conductivity, whether it is external heat trying to enter the storage tank or internal cold or heat emitting outward, and encounters the first barrier here. The reflective heat insulation layer 202 is located in the middle, which reflects a small amount of radiant heat that passes through the heat insulation material layer 201 back to reduce heat exchange. The outermost protective structure layer 203 protects the internal two-layer structure from external damage and environmental erosion, maintains the overall performance of the heat preservation assembly 2, effectively solves the problem of poor heat insulation effect and easy heat loss of traditional single-layer heat preservation material, creates a stable temperature environment for the storage tank, reduces the working load of the refrigeration and heating system, and reduces energy consumption.
