Pear slice drying case

Shanxi Zhangzong is a company specializing in deep processing of fruits, hoping to develop a high-quality dried pear slice product for retail and food raw material supply. However, due to the significant impact of weather on traditional air drying methods and uneven drying, the products are prone to oxidation, discoloration, and poor taste. Therefore, they need to find efficient and stable pear slice dryers to improve product quality and extend shelf life through scientific drying process solutions.

1. Customer demand analysis:

① Improve drying efficiency: shorten drying time and reduce energy consumption.

② Maintain color and taste: Avoid oxidation and blackening of pear slices to ensure crispy and sweet texture.

③Extend shelf life: Ensure that the product is not easily affected by moisture or mold during storage.

④ Adapt to large-scale production: The process needs to be stable and suitable for batch processing.

2.Solution: Customized pear slice drying process

①Preprocessing optimization

Accurate cutting: Using an automatic slicer to ensure uniform thickness of pear slices (3-5mm) and improve drying consistency.

Antioxidant treatment: Soak in citric acid solution (1:4 ratio) to effectively prevent browning and keep pear slices golden and translucent.

②Intelligent drying solution

Equipment selection: It is recommended to use Jinlu Machinery multi-layer heat pump dryer, with precise temperature control at 60-70 ℃, which is energy-saving and efficient.

Drying process:

Phase 1 (60 ℃, 2 hours): Low temperature slow drying to remove surface moisture.

Second stage (65 ℃, 4-6 hours): Accelerate water evaporation, regularly flip to ensure uniform heating.

Phase 3 (70 ℃, 1 hour): High temperature short-term sterilization to improve product shelf life.

③Packaging and Storage Suggestions

After drying, cool to room temperature and use vacuum packaging and deoxidizer to prevent moisture regain.

Storage environment: cool and dry place, with a shelf life of up to 12 months.
