Ointment manufacturing and herbal product processing equipment are poised to become a significant trend in the food industry, driven by the growing demand for healthy and nutritious food options. Freeze-dried foods, known for their superior nutritional quality, are expected to emerge as a market hotspot in the coming years and could revolutionize the health and wellness sector.
The process involves freezing the water content in food into ice, followed by converting the ice into gas at a high temperature, effectively dehydrating and drying the food. This dehydration allows for long-term preservation, as microorganisms and enzymes cannot thrive without water. When rehydrated, the food restores its original state, retaining its appearance, color, fragrance, taste, and shape. The low-temperature and oxygen-poor drying conditions ensure minimal nutrient loss, making freeze-dried food as nutritious as its fresh counterpart. Additionally, with over 95% dehydration, freeze-dried food boasts an extended shelf life. Properly packaged, it can be stored at room temperature for over five years without preservatives, offering lightweight and convenient transportation.
For food processing, the advantages of this equipment are evident: it effectively controls moisture, inhibiting microbial growth and extending shelf life. During the sublimation process, the food's structure remains intact, ensuring excellent instant solubility and rapid rehydration. Nutrients like vitamin C are preserved, and the food maintains its original traits. The packaging, typically vacuum-sealed or nitrogen-filled, and stored in darkness, further enhances its shelf life and ease of preservation.
