Prickly Pear Powder Freeze Dryer

The freeze-drying machine manufacturers are here to sort out the production process of the prickly pear powder freeze dryer machine for deep processing of the prickly pear freeze-dried powder: raw materials → cleaning and impurity removal → juice extraction → centrifugal filtration → freeze-drying → crushing → packaging. The specific operation points are as follows:

1. Raw material pretreatment: including cleaning, impurity removal, juicing, centrifugation, filtration and other steps.

Choose the fresh fruit of about eight mature prickly pears that are free of pests, damage, and mildew, wash with tap water, remove the dust and debris, and repeatedly squeeze it with a juicer 3 times, and the last two times are in the squeezed prickly pear residue. Add an appropriate amount of water to mix, in order to facilitate the separation of the active ingredients in the prickly pear by juicing as much as possible. Collect the thorn pear juice squeezed 3 times for filtration and centrifugation to remove dust, prickly pear seeds, pomace, and other foreign matter. According to different product requirements, it is decided whether to carry out ultrafiltration to separate small molecules such as vitamin C. Finally, the processed prickly pear juice is transferred to a freeze dryer for pre-freezing.

2. Lyophilization: including pre-freezing, sublimation drying, desorption drying

2.1. Pre-freezing: The pre-freezing temperature is set at -30℃. After the material has reached below -30℃, keep it for a period of time (generally more than 1h) to ensure that all the moisture in the material is frozen.

2.2. Sublimation drying: also known as primary drying. After the material is pre-frozen, the heating plate starts to heat up. During the heating process, the temperature of the material is always kept below but close to the eutectic point, so as to facilitate heat transfer and sublimation.

2.3. Desorption drying: also known as secondary drying. Although there is no frozen ice in the product at this stage, there is still about 10% moisture in the product. In order to make the product reach a qualified moisture content, the product must be further dried. That is desorption drying (two dryings). At this stage, the temperature of the plating layer can be rapidly increased to the maximum allowable temperature of the product and maintained until the end of freeze-drying.

3. Post-processing: including crushing, packaging, and storage.

The dried prickly pear freeze-dried powder is lumpy and must be properly crushed before packaging. Since the prickly pear freeze-dried powder has a strong ability to absorb moisture, the pulverization must be carried out in an environment with humidity lower than 40%.
