Sugar unloading flow for blowing scraper of sugar making separator

Abstract

The invention relates to a sugar unloading flow for a blowing scraper of a sugar making separator. The flow comprises the following steps of: (1) preparing an oil-free compressed air system when the sugar making separator works; (2) after the sugar unloading flow begins, reducing the rotational speed of a rotary basket of the sugar making separator to 2 to 6 revolutions per minute from 1,150 to 1,250 revolutions per minute, and delivering oil-free compressed air to the blowing scraper; (3) making the blowing scraper close to the inner wall of the rotary basket, and beginning unloading sugar; (4) making the blowing scraper move from the top to the bottom along the inner wall of the rotary basket, and gradually unloading the sugar layer on the wall of the rotary basket from the top to the bottom till the blowing scraper moves to the lower end of the rotary basket; and (5) when the blowing scraper stops moving after moving to the lower end of the rotary basket, closing a valve of the oil-free compressed air system, meanwhile, returning the blowing scraper to a stop position, thus, finishing the sugar unloading flow, and preparing a next separation cycle. The flow can remove the residue phenomenon of a sugar particle finished product from the surface of the rotary basket during unloading the sugar, and can shorten the sugar unloading time at the same time.

Description

technical field [0001] The invention relates to a sugar unloading process in a sucrose production process, in particular to an air-blowing scraper unloading process of a sugar separator. Background technique [0002] White granulated sugar has various specifications such as coarse granulated sugar, fine granulated sugar, fine fine sand, etc., but it is all sucrose crystals, which are extracted from the stems of sugarcane or the roots of sugar beets through a complicated process. Its general process includes pressing, juice extraction, treatment, steaming, crystallization, separation, drying and sieving, packaging and other processes. The closer to the back of the process, the more labor in the previous process is included in the product. Therefore, reducing defective products and reducing the return and repeated circulation of finished products is an important aspect of improving production efficiency. The process and equipment of each link are worthwhile. Careful study. ...

AI Technical Summary

Problems solved by technology

The inner diameter of the rotating basket of the separator is 0.8 meters and the height is 1.05 meters. There is always a gap between the scraper and the rotating basket when unloading the sugar. Calculated by 0.5 mm, the residual sugar after each unloading is about 0.4 liters; however, every 3 minutes unloading One time of sugar, after 150 days of one cropping season, the total residual sugar of each separator will reach 30 cubic meters, with a combined weight of more than 40 tons.
