The production process of Shandong dextrin is mainly completed in a central baking device, which has the function of uniformly adding flavor and quickly removing volatiles. The ideal baking equipment is a fluidized bed device. The powder will float in the high-temperature airflow. Therefore, it will be heated quickly and evenly and acid added and volatiles removed, the reaction is uniform,Pharmaceutical dextrinquality is easy to control, therefore, this is a reaction device with excellent performance.

Pharmaceutical dextrinThe entire production process can be divided into the following five processes:

1. Acidification: Acidic substances are added to the powder in the form of gas or mist-like liquid.

2. Pre-drying: Usually, the acidified starch is dried before heating. In order to minimize the hydrolysis reaction during the dehydration process, the pharmaceutical dextrin operation should be carried out at a relatively low temperature, otherwise a higher reducing sugar value will be produced, i.e., dextrin. The product quality is usually determined by this process, meaning that the content of reducing sugar in this process directly affects the hygroscopicity, binding property, color, and fluidity of the product.

3. Cooking: Several cooking methods can be used: one is an open cooker, which has a relatively simple structure, and the other is a vacuum cooker. The structure is similar to the open cooker, but it works under negative pressure, which is conducive to drainage and facilitates material flow.

4. Cooling:Pharmaceutical dextrinwill be transferred to the cooler for cooling to stop the reaction.

5. Re-humidification: After the reaction, the moisture content of the product is 0.5% to 0.3%. Usually, the product is humidified before bagging, which makes the Shandong dextrin product more stable during storage.

Shandong dextrin is widely used in food such as candy, malt extract, fruit tea, milk powder, ice cream, beverages, canned food, etc., and it is a filler and yellow dextrin regulator for various foods.
