One of the ways to shorten this time is to use sublimation dried pumpkin powder to cook directly, saving time and convenience, but the main values inherent in pumpkin do not have a great influence. .
Usually, when it comes to drying, many people think of using heat to dry products, but now apart from this popular method, there are more modern drying methods such as freeze dryer, sublimation drying… And in this article In this writing, SUNSAY would like to share with you the process of processing and making sublimation dried pumpkin powder.
About the principle of sublimation drying
As described in many articles as well as previous introduction, the principle of sublimation drying is to apply the sublimation phenomenon of ice to dry the product. The freezing temperature in the drying chamber must reach -30 degrees Celsius to ensure the requirements for sublimation drying, and the pressure must be as low as 15-50pa.
Pumpkin sublimation drying process consists of 2 main stages:
• Freezing process – this is the first stage of sublimation drying process
• Sublimation process – this is the stage of removing water to dry the ingredients.
Because of this special product drying process, pumpkins dried with a sublimation dryer will not be affected in terms of product color, natural structure as well as nutritional value.
Pumpkin sublimation drying process
Step 1: Clean and prepare the pumpkin, cut into short pieces and arrange them evenly on the drying tray.
Step 2: Carry out quick freezing of carrots at a temperature of -30 to -50 degrees Celsius
Step 3: Put into a vacuum chamber, so that the ice crystals inside the carrots will sublimate without going through the liquefaction stage. This is also the stage when about 90% of the moisture in the pumpkin has been drained.
Step 4: Conduct secondary drying to evaporate residual moisture, adjust temperature gradually up to 0 degrees Celsius, moisture in carrots remains 1-4%
Step 5: Take the pumpkin out and vacuum pack it, prevent moisture and prevent oxidation.
