When sourcing a pie machine, you must evaluate the production capacity (pieces per hour) to ensure it meets your output requirements. Key technical factors include mold customization options for different shapes and sizes, temperature control precision for consistent baking or forming, and material composition, where food-grade stainless steel (SUS304) is the industry standard for durability and hygiene. Additionally, check the automation level—fully automatic lines reduce labor costs, while semi-automatic machines offer more flexibility for artisanal products.
