Sorbitol, also known as sorbitol. The molecular formula is C6H14O6 and the molecular weight is 182.17. It is white hygroscopic powder or crystalline powder, flakes or granules, odorless. Depending on the crystallization conditions, the melting point changes in the range of 88~102℃, and the relative density is about 1.49. Easily soluble in water (1g dissolves in about 0.45mL water), slightly soluble in ethanol and acetic acid. It has a refreshing sweetness, the sweetness is about half that of sucrose, and its caloric value is similar to that of sucrose.
1. Follow below to understand the correct storage method of sorbitol:
(1) When choosing product packaging, try to use packaging specifications that are consistent with the unit usage or have a smaller production usage.
(2) The packaging of the product is moisture-proof.
(3) Store in a dry and ventilated place. After taking it out for use, be sure to seal the bag. The product has good hygroscopicity, but caking problems may occur when the temperature difference is large. Therefore, it is not recommended to store it in a cold storage.
(4) Do not pile it too high to prevent the products at the bottom from being squeezed and agglomerated due to the stress of accumulation.
(5) Strengthen the dryness of the storage room. Measures such as putting some sawdust or lime on the ground can be taken to reduce local humidity. When conditions permit, machines such as dehumidifiers can also be used for treatment.
2. Opinions on preventing agglomeration during the production and storage of sugar alcohols (for reference only):
(1) Since the partial pressure of water vapor in the air at the storage temperature is less than the partial pressure of water vapor in the air when packaging pure materials, water will condense on the crystal surface. A solution is formed on the surface of the crystal. When the air humidity decreases, the water on the surface evaporates, causing crystal bridges to form at the contact points of the crystal grains and bond them together. Therefore, try to lower the packaging temperature as much as possible. Prevent the formation of condensation water when the temperature is lower than 30°C during storage and transportation; when the temperature is higher than the condensation temperature, the water evaporates. This causes clumping.
(2) Strengthen screening to minimize the bridge formation of fine grains, causing agglomeration.
(3) Because the wind entering the cold wind section is saturated with water vapor at this temperature. When the material layer is blown into the material layer, the temperature of the material layer is lowered. At the same time, the air temperature increases, the humidity increases, and the moisture is taken away. Although the temperature of the frozen air after dividing the water can enhance the evaporation of the material moisture. However, during packaging, saturated steam partial pressure at a higher temperature between the material grains will still be formed. Therefore, it is recommended to strengthen water separation measures after freezing. After the air is dehydrated, it no longer heats up.
(4) Establish a regular return stacking system. Prevent capillary adsorption between particles under long-term stacking pressure, causing water vapor diffusion.
