The pastry sealing machine is an automated/semi-automated device designed specifically for pastry packaging. Its core function is to preserve freshness, prevent dust and pollution, and extend shelf life by sealing the package while improving the appearance of the product. Its application scenarios cover the entire chain of pastry production, circulation, and sales.
Pastry manufacturers (such as bakeries, cake factories, and pastry factories) are the primary users of sealing machines, primarily for end-of-line batch packaging. These machines are suitable for standardized, industrialized production. Their specific application features are as follows:
Applicable Pastry Types: Various pre-packaged pastries, including but not limited to:
Baked Goods: Sliced bread, chiffon cake, Swiss rolls, egg yolk pastries, and wife cakes;
Chinese Pastries: Mooncakes, peach pastries, twisted dough sticks, and mung bean cakes;
Frozen/Refrigerated Pastries: Mousse cakes, snow meringues, and tiramisu (requires use with anti-fog film or low-temperature-compatible sealing technology).
Core Application Value:
Standardized Sealing: Through precise mechanical control of temperature, pressure, and sealing time, each package of pastries is ensured to have consistent seal strength (preventing leaks or incomplete seals), complying with food safety production standards (such as the sealing requirements for packaging in GB 7718, "General Rules for Prepackaged Food Labeling"). Extending Shelf Life: Vacuum packaging and nitrogen-filled packaging (supported by some high-end sealing machines) isolate oxygen and microorganisms, extending the shelf life of pastries from 1-2 days to 7-30 days (e.g., from 3 days to 15 days for room-temperature cakes), facilitating cross-regional transportation and inventory management.
Improving Production Efficiency: Continuous sealing machines (such as chain conveyor and rotary types) can seal 30-100 packages per minute, replacing manual sealing (which only operates at 5-10 packages per minute). This meets the production needs of companies with daily production capacity of thousands to tens of thousands of pieces.
