Freeze Dryer For Strawberry Powder

Fruit and vegetable freeze dryer is a drying equipment for the application of vacuum freeze-drying technology in food processing. It uses the sublimation principle to process fruits and vegetables through a vacuum freeze dryer to obtain freeze-dried fruits and vegetables with basically unchanged shape, color and nutritional composition. It has the characteristics of rehydration, can be stored at room temperature for 1 ~ 3 years and convenient transportation. At present, freeze dryer for strawberry powder is widely used in food processing.

The strawberry lyophilized powder treated by the lyophilizer has various vitamins and nutrients of fresh strawberries, preserves the original flavor and color, and has the characteristics of strong rehydration. Good quality freeze-dried strawberry powder needs to master exquisite strawberry freeze-drying technology and freeze-drying machine equipment to meet the freeze-drying process.

1) Pre freezing process: after the strawberries are prepared into slurry through freeze-drying pretreatment, they are loaded into the tray. The thickness of the tray solution is 1 ~ 1.5cm. First, they enter the fruit and vegetable lyophilizer for low-temperature pre freezing. According to the eutectic point of the strawberry slurry - 15 ℃, the pre freezing temperature is - 35 ~ - 40 ℃, and the required low-temperature pre freezing time is 240Min. The pre freezing process directly affects the efficiency of drying and sublimation in the later stage.

2) Vacuum freeze-drying process: after pre freezing, start pre vacuumizing, reach the set value of fruit and vegetable freeze-dryer equipment of 30Pa, and enter the primary drying stage. According to the change of saturated steam pressure on the ice crystal surface at different temperatures, the set temperature range of primary drying is - 28 ~ 30 ℃, the vacuum adjustment value of freeze-dryer equipment is 30 ~ 50pA, and the set drying time is 10 ~ 13 hours. The drying requires that there are no bubbles on the material surface, No collapse, no discoloration, remove about 90% of the water. Analytical drying is carried out after the primary drying, because analytical drying is to remove about 10% of the bound water and needs to supply more energy. In the heating process, it is necessary to ensure the temperature of ice crystal dissolution and the temperature of active substances affecting strawberries. Therefore, the analytical drying temperature range is 30 ~ 60 ℃, and the vacuum value of fruit and vegetable vacuum freeze dryer is 20 ~ 30Pa, The drying time is 6 ~ 8 hours. The drying requires that the materials do not coking and decompose, collapse or change color. After drying, the strawberry lyophilized powder with water content of about 3% is obtained.

3) Equipment selection of fruit and vegetable lyophilizer: the material of box, diaphragm, condenser and material tray shall be 304 stainless steel to ensure that it meets the requirements of GMP food safety. The temperature control range of the diaphragm of the lyophilizer is: - 45 ~ 80 ℃, the temperature of the condenser is - 65 ~ 70 ℃, and the condensation capacity is strong to ensure the drying and water capture capacity. It is required that the vacuum freeze dryer has the ability of vacuum fine adjustment to improve the drying efficiency. PLC electric control of freeze-drying machine equipment has the functions of process setting, modification, data storage, freeze-drying curve query, slope temperature control, data tracing and management. At the same time, FZG fruit and vegetable freeze-drying machine has remote monitoring and operation functions to realize industrial management.

Good freeze-drying technology and high-quality fruit and vegetable freeze-drying machine equipment can freeze-drying process high-quality strawberry freeze-drying powder. FZG fruit and vegetable freeze-drying machine equipment factory is a fruit and vegetable freeze-drying machine processing enterprise, providing freeze-drying technology and complete sets of equipment integration solutions to help the development of fruit and vegetable deep processing.
