Description

The present invention is the method and apparatus that plant stem-leaf is separated into plant and fiber.

Plant stem-leaf generally contains crude fibre more (20-40%), and crude fibre can consumed energy during by fowl poultry alimentary canal, and the final overwhelming majority will be discharged from ight soil, must take away a large number of nutrients during discharge, calculate according to result of the test, pig eats a kg of fibers can lose two kg body weight, moreover, the plant stem-leaf internal structure is loose, volume is big, although fills up the nutritional need that stomach also can't satisfy animal, so, plant stem-leaf is raised fowl poultry poor effect, excessive feeding may losing more than gain.Traditional green and rough feeds (referring generally to careless class and crop stalk class) processing method comprises methods such as pulverizing, boiling, fermentation, alkalization, only change the form and the structure of feed, do not change composition, fiber content does not subtract, therefore the palatability of feed can only be improved, its nutritive value can not be improved.The leaf protein processing method is an exception, and it is fresh and tender leaf to be broken into slurry extrude juice, leach the leaf protein grumeleuse through the after heat of heating, but this method only can reclaim dry 9%, and cost is very high, is unsuitable for generally adopting.

The method and apparatus that the purpose of this invention is to provide a kind of separating plant cauline leaf separates nutrients in the plant stem-leaf and fiber, makes nutrients give full play to trophism and avoids the influence of fiber negative interaction, and recycled fiber is applied to building industry, paper-making industry simultaneously.

The method of separating plant cauline leaf of the present invention is: at first raw material is prescinded or pulverizes, then material is floated on water, make silt and metal sundries the precipitation and remove, through fragmentation and clear assorted material as through pressure cooking, make interfibrous lignin plasticizing, it is cataclasm that the material deliquescing then helps to reduce fiber, and the nutritious cell of short circle separates completely with elongated fibrocyte.Send into and carry out defibrination in the fiberizer through pulverizing, assorted and softening clearly material.During defibrination, material is subjected to the repeatedly interrupted extruding of movable grinding disc and fixed millstone and friction and attenuates, fiber is discongested, brooming, aquation make to plant and lose bonding state between powder and fiber and form admixture, the slurry water of wearing into flushing, utilize screen cloth that elongated fiber and powder suspension are separated, suspension is again through precipitation, filtration or centrifugal action and dewater, or drying, pulverizing and must plant powder again.Plant powder add join a small amount of conventional feed can be directly edible for domestic animal, also can prepare dry feed.Make fiberboard after fiber partly can dry and break up or be used for building and plaster, meticulous as softening defibrination, and screen to remove the gred and then obtain qualified paper pulp.

The equipment of separating plant cauline leaf provided by the invention is made up of hopper, return pipe, fiberizer, jumping sieve, sedimentation basin, discharge pipe, condiment tube etc.
