Abstract
In a continuous process for extracting sugar cane juices from sugar cane bagasse, the bagasse is conveyed through an extraction zone, sugar solutions of different concentration are delivered on to different sections of the surface of the bagasse within the extraction zone, the sugar solutions of different concentration being delivered to contiguous sections of the surface of that quantity of bagasse which at any one instant is present in the extraction zone in order of decreasing concentration with respect to the direction of movement of the bagasse through the extraction zone, the temperature of each of the sugar solutions is such as will render and/or maintain the tissues of the bagasse permeable and maintain the latter at a temperature not less than 65 DEG C. during its passage through the zone, the sugar solutions are allowed to percolate through the bagasse thereby making each of them more concentrated as a result of the extraction of sugar cane juices from the bagasse by diffusion and/or by lixivation and the more concentrated sugar solutions are collected, and the sugar solution delivered to any one of the sections of the surface of the bagasse is the solution collected as a result of the percolation through the bagasse of the next less concentrated sugar solution which was delivered to the adjoining section of the bagasse. The temperature of each of the sugar solutions preferably is such that the temperature of the bagasse is maintained in the range of from 65-75 DEG C. The pH of the sugar solutions should be between 6.2 and 6.5, and the retention time of the bagasse within the extraction zone from 20 to 30 minutes. Bagasse is fed in weighed quantities from a classifier into an extraction zone bounded by a metallic endless conveyer 7 moving over a fixed screen 9, longitudinal side walls 10, a clockwise-rotating (as viewed in the figure) adjustable height-limiting <PICT:1024428/C6-C7/1> drum 13 and an anti-clockwise rotating discharging drum 11. The sugar solution delivered to any one of the spray distributers, excluding f and g for fresh and sweet water, respectively, is that solution collected as a result of the percolation through the bagasse of the next less concentrated sugar solution which was delivered to the adjoining section of the bagasse. The saturation solution collected in tank 5e is passed through heaters 20 before delivery to the spray distributer e; the juice product is collected in tank 6f. The delivery, temperature and pH of the sugar solutions are regulated from a control panel 19. It is stated that the contents of any two of the collecting tanks 1a-6f may be mixed. The Specification discloses a method of calculating the relationship between the dimensions of the apparatus and its capacity.
