The present invention relates to a method for treating blackstrap molasses. More specifically, the present invention relates to a method for efficiently and continuously separating calcium content, solid content, etc. in blackstrap molasses, and recovering sugar content in blackstrap molasses. In the sugar refining process in the sugar industry, lime is commonly used to clean the juice of cane or the like (to remove starch, wax, phosphates, etc.). Therefore, blackstrap molasses, a by-product, generally contains calcium. Most of the calcium content is in the form of calcium ions, and a part is in the solid state as poorly soluble salts such as calcium carbonate, usually 1-5% in blackstrap molasses. Therefore, if this blackstrap molasses is used as a raw material for fermentation, the solids mainly containing calcium may cause scale to occur during the refining process of fermented products, and calcium residue in the product may become a problem. There are many. Therefore, various methods for treating blackstrap molasses have been studied to remove the solids and calcium content from the blackstrap molasses and to effectively utilize the sugar content in the blackstrap molasses. Conventionally, the method for removing suspended solids mainly composed of calcium from blackstrap molasses is to dilute the blackstrap molasses with water, add sulfuric acid, phosphoric acid, etc. to it, then heat treat it, and then centrifuge it. A known method is to remove calcium as a sparingly soluble salt such as gypsum or lime phosphate. However, in the conventional method,
Continuous separation operations were often not possible for long periods of time due to scale, etc. adhering to the surface of centrifuge separation plates and piping. In addition, the separated suspended solid substance mainly composed of calcium salts contains a large amount of sugar. As a method for effectively recovering the sugar, for example, water is added to a suspended solid material mainly composed of calcium salts separated by the above method, and then centrifugation is performed to separate the solid material and a sugar-containing liquid. Attempts have been made to recover sugar. The method of continuously treating blackstrap molasses by recycling the recovered sugar-containing liquid has been partially realized by improving the heating method, but even in this improved treatment method, the type of blackstrap molasses, the lot size Scaling occurs due to such factors, and it is not yet a satisfactory continuous treatment method for blackstrap molasses. The present inventors have studied various methods for processing blackstrap molasses, and have found that (1) a step of diluting raw blackstrap molasses to 40-70°BX, (2) a step of adjusting the pH of the diluted liquid to 3.5-5.2,
(3) heating the solution after pH adjustment to 50°C or higher; (4) aging the heated liquid for 10 minutes or more; (5) separating solids mainly composed of calcium salts and sugar-containing liquid from the aged liquid. (6) the step of adding 0.5 times the volume or more of water to the solid material mainly composed of calcium salts separated in the main step; (7) the step of aging the water solution for 10 minutes or more; (8) Continuous production of blackstrap molasses using a cycle process in which the solids mainly containing calcium salts and the sugar-containing liquid are separated from the ripening liquor, and (9) the separated sugar-containing liquid is used to dilute the raw material blackstrap molasses in the main process. By establishing a unique processing method, we discovered a method to efficiently and continuously separate the calcium content, solid content, etc. in blackstrap molasses, and also to efficiently and continuously recover the sugar content in blackstrap molasses. Completed the invention. The present invention, which continuously processes blackstrap molasses, has made it possible to utilize the sugar in blackstrap molasses extremely effectively. The feature of the present invention is that both the main process and the cycle process are provided with an aging process, and furthermore, both processes are combined. The present invention will be explained in detail below. The steps of the blackstrap molasses treatment method of the present invention are shown below.
