Bolaike Completes Freeze-Drying Test for Organic Water Bamboo: Intact, Milky-White Appearance; Crisp and Tender After Rehydration

Water bamboo is a popular seasonal vegetable in the Jiangnan region, known for its high moisture content and tender texture. However, fresh water bamboo is difficult to store and has a short shelf life. Processing it into freeze-dried products can not only extend the shelf life but also maximize the retention of its shape and flavor. Recently, Jiangsu Bolaike Refrigeration Technology Development Co., Ltd. (hereinafter referred to as "Bolaike"), commissioned by a client, completed a freeze-drying process test for organic water bamboo using its industrial freeze-drying equipment. The client had high expectations for the freeze-dried appearance of this organic water bamboo.

On the day of the test, Bolaike's technical team received the organic water bamboo sent by the client. This type of water bamboo is full of moisture with tender flesh, placing high demands on the freshness-locking capability of the freeze-drying process. The team washed and sliced the water bamboo, spread the slices evenly on trays, and loaded them into the freeze-drying chamber.

The equipment used in this test was Bolaike's 1-square-meter silicone oil version freeze dryer. The equipment can reach a minimum temperature of -35°C and uses an industrial-grade silicone oil circulation system, which can rapidly freeze the water bamboo slices thoroughly, fully locking in their internal structure and fresh texture. During the drying stage, the equipment works in conjunction with Bolaike's multi-stage slow heating freeze-drying process to precisely control heat input, preventing the water bamboo from collapsing or deforming during dehydration.

The freeze-dried water bamboo slices after coming out of the chamber present a natural milky-white color and intact shape. They look clean and fresh, with a faint, pleasant aroma when brought close. Technicians conducted a rehydration test. After soaking the freeze-dried water bamboo slices in water for a few minutes, they quickly returned to a crisp and tender state close to that of fresh water bamboo, with a moist texture and the original flavor well-preserved.

As an internationally recognized industrial freeze-drying equipment manufacturer, Jiangsu Bolaike has accumulated more than 200 patents. It is a technology-leading enterprise in the domestic food freeze-drying equipment field and the only enterprise in the national freeze-drying equipment industry to have won the highest provincial science and technology awards in both Shandong and Jiangsu provinces. The company's technical accumulation can be traced back to 2003. Its products cover a full range of freeze dryers from 0.5 square meters to 200 square meters, widely used in the food, pharmaceutical, and biotechnology fields.
