TH13003EX - Processes for extraction of feed and equipment for operations - Google Patents

Abstract

Let the extractor, which is preferable to a sodium hydroxide solution with 0.2 to 0.7% NaCH, flows from the bottom to the top through Layer of mashed peat And taken to the top through the floor Of mashed feeds And removed from the floor At a speed at Causing the outflow to be smooth And extracts that were without Solid particles of the extracted feed, if appropriate, the extractor should be added and allowed to flow through the layer again. The process equipment has at least one hopper for extractor (NaOH), at least one extraction tank (E), and at least one recirculation tank (Z) for the body. Extraction nourished with extracts The feed pipe with the pump (P) placed and the hopper (NaOH) and from the recirculation tank (Z) to the side pipe. The bottom is coming from each extraction tank (E), while each extraction tube (E) coming from the top is connected to the respective recirculation tank (Z).

Claims (2)

1.Process for feed extraction With the characteristics that the extractor is allowed to flow through a fine layer of feed, it should be sifted to a particle size of approximately 8 to approximately 30 mm from bottom to top at the A flow that makes the flow smooth. And the extracted There are feed particles to be extracted in it. Ideally, it should be at a speed of 1 to 10, preferably 4 to about 7 cm / min. 2. The process according to claim 1 looks at whether the extractor There is a feed component removed above the feed layer and, if appropriate Should instead of some new extractors, let them flow through the floor at least one more time.
