Lychee Food Freeze Dryer

Lychee Food Freeze Dryer

Lychees have high economic value, but fresh lychees are prone to spoilage due to their short shelf life. Dried lychees greatly extend the shelf life and add value to the product. The traditional lychee drying method is sun-drying and hot-air drying. The drying quality is difficult to guarantee, the processing time is long, and the loss of nutrients is large. Therefore, it is urgent to develop new lychee drying processes and new equipment.

The application of freeze-drying technology in agricultural and sideline products to process freeze-dried products can keep the original nutrients of agricultural products to the greatest extent, and the shape, color, smell, and taste are basically unchanged, and freeze-dried products can be stored in room temperature. The water is easy, and the lyophilized product after rehydration is very close to the fresh product.

Precautions for the use of lychee food freeze dryer machine: Because the lychee fruit film has a strong inhibitory force on the migration of water from the pulp and the core, and the cost of freeze-drying processing is high, lychee is not suitable for freeze-drying of the whole fruit, and needs to be peeled and dried. The pits and fruit membranes were removed and freeze-dried under a vacuum.
