Chain bakery stores specialize in freshly baked bread, premium cakes, Western pastries and cream desserts. These delicate products impose extremely high requirements on temperature and humidity control for raw material storage, semi-finished product standing and finished product preservation. Adopting the operation mode of centralized stock preparation and daily on-site baking, chain bakeries demand high-capacity, high-stability and low-consumption professional refrigeration equipment. Traditional household-grade refrigerators feature unstable temperature fluctuation, insufficient capacity, frequent frosting and substandard hygiene conditions. These shortcomings easily cause inconsistent dough fermentation, dessert drying and deterioration, and high raw material wastage, failing to meet the standardized quality control requirements of chain bakery brands.
