How to Dry Green Beans?

With the arrival of the summer vegetable harvest season, green beans, a common ingredient on the table, are perishable, making their preservation a key concern for many families. In recent years, drying green beans, a traditional preservation method, has seen a resurgence thanks to modern technology. Jinlu Machinery takes an in-depth look and reveals the secrets to scientifically and efficiently drying green beans.

1.The Collision of Tradition and Modernity

Green bean drying is not new. In the past, people typically relied on natural sunlight to dry green beans, but this method was highly susceptible to weather and susceptible to dust, insects, and ants. Today, with the widespread adoption of home food dryers and low-temperature air drying technology, more families are opting for more controlled and hygienic drying methods.

2.Scientific Steps: From Cleaning to Storage

Selection and Cleaning: Choose fresh, tender green green beans and remove any that have insect holes or rot. Rinse thoroughly with clean water and drain thoroughly.

Pre-treatment: Cut beans into even sections (approximately 5 cm long) and blanch in hot water for 2-3 minutes (add a small amount of salt to preserve color). Remove from heat and quickly rinse with cold water. Drain.

Drying Methods:

① Sun Drying: Spread beans flat on a bamboo sieve or air-permeable mesh rack in a sunny, well-ventilated area, away from the ground. Leave to dry for 2-3 days, removing them at night to prevent dew.

② Dryer Operation: Spread beans evenly on a drying tray, set the temperature to 50-60°C, and dry for 6-10 hours, until crisp and easy to break.

Storage: Store thoroughly dried beans in a sealed bag or glass jar with a desiccant in a room temperature container for over six months.

Home Use: Efficiency and Convenience

Ms. Zhang shared, “I use my home dryer to process 5 kilograms of beans at once. The finished product is very convenient for stewing meat or making soup. Compared to freezing, drying beans takes up less space and has a richer flavor.”

Market Trend: Small Appliances Are Popular

With the rise of healthy eating awareness, sales of home food dryers have grown significantly in recent years. Drying functions for vegetables like beans and mushrooms are particularly popular.
