Each method of drying products from fruits, vegetables, fish, meat, medicinal herbs, powder solutions… has a different principle or heat transfer method, each heat transfer method will have its advantages and disadvantages and appropriate applications. In this content, we will learn about heat transfer methods to products on freeze dryers, hot dryers and heat pum...
The current solvent cooling system /solvent heat transfer system/ is probably no longer strange to users of large freeze dryers, specifically 10kg or more. However, with small dryers of 3kg and 5kg, only MactechDryer are currently fully applied, the rest of the small machines on the market today are still indirect heat transfer with the...
The pressure on the freeze dryer is one of the important parameters that dryer users need to understand to be able to monitor, check and identify problems related to the vacuum system during the drying process. In this content, the author will analyze carefully so that readers can easily understand. The image above is drying...
The Pressure drying mode is one of two drying options for the sublimation dryer, Currently, we all choose this drying mode to ensure the optimal and fastest drying process. In this content we will learn more to clearly understand how the machine operates when using this drying mode. The freeze dryer is a device that...
You want to learn about freeze drying techniques, product drying techniques using freeze dryers, drying processes or freeze drying technology processes, or a similar name, then in this content the Mactech will analyze the steps of drying products with whole lotus-marinated tea for Readers to better understand. This will help you know the appropriate drying...
When it comes to freeze drying time of a certain product, we are also interested in this factor because it reflects productivity as well as power consumption. However, the most important factor when using a sublimation dryer (freeze drying machine) is the quality of the product, the value of the dried product is very high,...
Mactech has now updated the new generation freeze drying program to ensure faster drying time than before as well as making it easier to set parameters when first starting use. In this content, you will be guided to use and understand the advantages of the pressure-based drying controller. In the principle of freeze drying or...
If you are learning about pressure on the freeze dryer, the content or information will be different from what is analyzed in this content, because sublimation pressure is the value that creates the pressure threshold for the dryer to provide heat for the product on the drying tray, thereby determining the sublimation of ice in...
The freezing stage is extremely important in the freeze-drying process because it affects not only sublimation quickly or slowly of the ice in product, but also the proper operation of the related components. Therefore, we need to pay more attention to this first step to ensure the most effective drying process. Freeze drying is a...
