Abstract
The production process of tea seed dregs fodder includes crushing tea seed dregs into fine grains, mixing tea seed dreg grain in 10-50 wt% and other fodder material, and feeding to a screw bolt puffing machine, shearing, extruding and rubbing in the cavity of the puffing machine at 150 deg.c temperature and 2 MPa pressure, extruding out and cutting into the puffed granular fodder. The present invention is suitable for production of tea seed dregs and treatment of pollution caused by tea seed dregs.
Description
Technical field:
The present invention relates to utilize the tea dregs of rice to be processed into the method for feed.
Background technology
The tea dregs of rice claim leached tea oil slag again, are that the fruit of plant of theaceae tea oil tree squeezes the dregs that are left behind the tea oil.In most of knob of China south seven provinces, the plantation of oil tea is with a long history, and cultivated area is very wide, the existing oil tea area 40000km in the whole nation
2, the annual about 650kt of tea seed that produces, the leached tea oil slag after the oil expression is more than 400kt.According to Primary Study, contain numerous nutritional labelings such as protein, fat, starch and mineral matter element in the tea dregs of rice, also contain 12% the crude protein of having an appointment in the grouts after the oil expression.But owing to contain noxious material Tea Saponin (also claiming the tea saponin) in the tea dregs of rice, at present, very few to its research both at home and abroad, the technology of detoxification and method are all imperfect, cause the utilization of the tea dregs of rice to be subjected to considerable restraint, except that a small amount of tea dregs of rice extracted Tea Saponin, the tea dregs of rice were not exploited basically, and most of tea dregs of rice go out of use and contaminated environment substantially.
If directly use tea dregs of rice nutrition purposes, especially for feeding animals, palatability is bad, is not suitable for doing livestock and poultry feed.The tea dregs of rice contain Tea Saponin, and to the cold-blooded animal toxigenicity, the tea dregs of rice of detoxification can not be used for feeding fish.Therefore, the detoxification of the tea dregs of rice is that tea dregs of rice feedization at first needs the problem that solves.In recent years, the method for processing tea dregs of rice detoxification has the hole to bury fermentation method, alkali disintoxication, water extraction, solvent method.Adopting the hole to bury the fermentation detoxification not only needs to dig pit, seal, and need reach the time of two weeks to month; The alkali disintoxication need add aqueous slkali, boils, filters, dry, and the alkali disintoxication also can destroy protein; Water extraction need add hot water, insulation, centrifugal elimination solution, lixiviate repeatedly, oven dry; Solvent method need also will be dried tea seed porphyrize, adding ethanol with a large amount of clear water lixiviates again; Existing method is not only loaded down with trivial details time-consuming but also effect is not good enough.Therefore, the tea dregs of rice will reach feedization also needs special processing.
Summary of the invention
The technical issues that need to address of the present invention provide and a kind of the discarded tea dregs of rice are become the method for feed, both can alleviate the feed deficiency, can eliminate tea dregs of rice problem of environment pollution caused again.
Technical scheme of the present invention is the tea dregs of rice to be gone to pulverize behind the straw earlier to mix with other feedstuff, sending into mixer after it is characterized in that adopting 10%～50% tea dregs of rice and other feedstuff and additive being optimized proportioning fully mixes, the draw ratio of sending into extruding screw again is 3: 1 a bulking machine, raw material process in the bulking machine chamber is sheared, is pushed and friction, temperature rises to 150 ℃, pressure and is raised to 2MPa, extrude expanded rapidly from the nib of die head, through cutting into graininess, the feed of expanded one-tenth particle can be packed then.
The present invention adopts evenly mixing with other feedstuff behind the coarse-grained tea dregs of rice raw material pulverizing beading shape, and the best proportioning of preferred and other feedstuff, the draw ratio that adopts extruding screw simultaneously is 3: 1 a specific bulking machine, can make raw material process in the bulking machine chamber shear, push and friction, temperature rises to 150 ℃, pressure rapidly and is raised to 2MPa and reaches best melting state, when material from the nib demoulding in a flash, the water acting of vaporizing in a large number is about to the tea dregs of rice and other feedstuff and becomes expanded pellet diet fully.Adopt this expansion method not need additionally to add other material, processing technology is simple, in process time in only several seconds, tea dregs of rice virus elimination rate is reached more than 99%, and have the technique effect that improves the feed palatability.
Description of drawings
What accompanying drawing 1 was represented is process flow diagram of the present invention;
Accompanying drawing 2 expression be the extruding screw schematic diagram of the bulking machine that adopts of the present invention;
Accompanying drawing 3 expression be the die head vertical section schematic diagram of the bulking machine that adopts of the present invention.
The specific embodiment
Implementing best way of the present invention is that the tea dregs of rice are gone to be ground into acinous behind the straw, optimize with 10%～50% tea dregs of rice and other feedstuff and additive and to send into mixer after the proportioning and fully mix, the draw ratio of sending into extruding screw again is 3: 1 a bulking machine, rotate in sleeve by extruding screw, the linear velocity of extruding screw is set in 2.0m/s compound is produced shearing, extruding and friction, temperature in the Builking cavity is raised to 150 ℃, pressure is raised to 2MPa, when material reaches expanded from moment of the nib demoulding, the nib of die head is established 1～3, die throat diameter is Φ 2mm～Φ 5mm, will extrude expanded material from the nib of die head then and cut into granular feed and pack.By the processing of this method enforcement to the tea dregs of rice, not only can make the tea dregs of rice become feed rapidly, also can avoid of the pollution of the tea dregs of rice to environment.
Claims (1)
- The processing method of tea dregs of rice feedization is that the tea dregs of rice are removed straw, mix with other feedstuff after being ground into acinous, fully mix after it is characterized in that adopting 10%～50% tea dregs of rice and other feedstuff and additive being optimized proportioning, the draw ratio of sending into extruding screw again is 3: 1 a bulking machine, raw material in the bulking machine chamber through shearing, extruding and friction, temperature rises to 150 ℃, pressure and is raised to 2MP a, extrude and through cutting into expanded pellet feed from the nib of die head.
