The main purpose of powdered activated carbon used in the food industry is to remove pigments and adjust flavors, deodorize, remove colloids, remove substances that hinder crystallization and improve product stability.

Sugar decolorization is one of the ancient applications of activated carbon. Around the eighteenth century, bone charcoal and charcoal were used in the sugar industry for decolorization. activated carbon suppliers Since the 20th century, bone charcoal has been gradually replaced by activated carbon. Sugar liquid contains a variety of colored substances, such as melanoidin, caramel and iron polyphenol complexes, among which melanoidin has a great influence on the color value of sugar crystals.

Activated carbon has a well-developed pore structure and coexistence of macropores, mesopores and micropores, so that it can effectively remove various colored substances. It has an excellent desorption effect on melanoidin, so it is widely used. In addition to the decolorization effect of powdered activated carbon manufacturers, activated carbon can also remove the gum and surface active impurities in the sugar solution, thereby increasing the surface tension of the sugar solution, reducing the foam during evaporation, increasing the cleaning speed, and improving the sugar crystals and molasses. seperate effect.
The activated carbon used in the sugar industry is usually called sugar charcoal. It is characterized by relatively developed coarse micropores, mesopores and macropores, and has a greater affinity for impurities in sugar and colored substances. .

Both powdered activated carbon and granular activated carbon can be used for sugar decolorization. The powdered activated carbon has a large surface area per unit volume, which can be processed in a short time and is easy to adapt to changes in the properties of the solution. The operation is mostly intermittent and small in scale. The granular carbon can be packed in the adsorption column for continuous operation, and can be recycled through regeneration, which is suitable for large-scale production.

The granular activated carbon sugar decolorization device mainly has two types of fixed layer type and moving layer type. The fixed layer type is a method with many applications. The powdered activated carbon manufacturer is convenient to operate and easy to maintain. bulk activated carbon pellets It can improve efficiency through multi-tower operation. The moving layer type has two ways of moving up and down. The quality of the sugar solution processed by this method Even and can also reduce the cost of enterprise production.
