Description
Technical field
The utility model relates to a kind of food, expanded feed machinery, particularly a kind of anti-wearing liner of bulking machine.
Background technology
Along with the development of food industry and feed industry and the raising of people's living standard, bulking machine has been widely used in producing various luxury foods and high-grade livestock and poultry material, it is strong that the food of process expanding processing or feed have mouthfeel, be easy to human body or livestock and poultry digest and assimilate, be easy to remarkable advantages such as storage, especially for the raw material puffed processing of content of starch 40 %, general requirement is high slaking product through the raw material after the expanding processing, by the raw material of high slaking is added in food or the feed as main formula components, perhaps directly the raw material of this high slaking is used as food or feed, such food or feed just are conducive to improve nutritional labeling and the final absorptivity that improves, and improve its edible mouthfeel.Expanding processing is by pressurizeing, add gentle humidification modifier treatment with preliminary treatment such as process impurity elimination, pulverizing, and promote material by Builking cavity inner screw spiral and form axial flow machinery and extrude nib, make it unexpected step-down and produce a kind of processing method of volumetric expansion.Screw rod is in the process that main axis rotation promotes, because the mechanical friction of screw rod and material, material and lining and material inside, material is pushed consumingly, stirs, shears, and makes material by further refinement, even.Along with the increasing gradually of pressure, the corresponding rising of temperature, under high temperature, high pressure, shear conditions, the rerum natura of material changes, become pasty state by powdery, starch gelatinization, albuminous degeneration, cellulosic are partly degraded, refinement, pathogenic bacteria are killed, and sanitary index improves, the toxic substance inactivation.When the moment of pasty material from nib ejection, under powerful pressure differential effect, material is by expanded, dehydration, cooling, the dilated product short texture, porous, crisp, and palatability and local flavor are preferably arranged, identical material is different at the curing degree that extrusion adds man-hour, pressure in curing degree and the expanded extrusion chamber, indexs such as temperature are relevant, so, there is crucial effects in the screw rod of bulking machine and the gap of lining to the quality of material puffing quality, and at present the Internal and external cycle of lining is smooth on the market, make the gap of this kind lining and screw rod at material from feed end to discharge end this process, the equipment running resistance is big, and lining is short service life.Therefore, above defective becomes the technical barrier of the industry.
Summary of the invention
The purpose of this utility model namely is to provide a kind of and can overcomes the deficiency that prior art exists, bulking machine anti-wearing liner simple in structure.
To achieve these goals, bulking machine anti-wearing liner of the present utility model comprises outer ring and inner ring, is characterized in: the shape of described lining inner ring is cylindrical or conical; Described cylindrical or conical inner ring is smooth or is distributed with some the grooves that can slow down discharge end pressure at circumference.
The above groove be shaped as rectangle or arc.
The groove of above-described rectangle or arc is 5～20.
Compared with prior art, the beneficial effect of this bulking machine anti-wearing liner is:
The utility model is reasonable in design, simple in structure, extruding efficient height, and equipment operates steadily, the durability height of lining, production cost is low, and production effect is remarkable.This anti-wearing liner is the expanded principle according to material, and the shape of lining inner ring is cylindrical or conical; Circumference at cylindrical or conical lining inner ring is distributed with some rectangles or arc groove, enter in the process that the inner chamber of screw rod and lining advances at material, intensified pressure gradually under the mechanism of propulsive force and frictional force, make expanded material in advancing, be subjected to extruding between lining and the screw rod fully, thereby generation high temperature, high pressure, the numerical value of high shear force slowly increases, when material enters the last discharging section of screw rod, the groove that has on the conical inner ring of lining or the columniform inner ring has played the effect that slows down discharge end pressure, this lining and the screw rod long service life that cooperates with it.

The specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is described.
As attached illustrated in figures 1 and 2, bulking machine anti-wearing liner of the present utility model comprises outer ring 1 and inner ring 2, and the shape of described lining inner ring 2 is conical, and described conical inner ring 2 is smooth.
As accompanying drawing 3 and shown in Figure 4, bulking machine anti-wearing liner of the present utility model comprises outer ring 1 and inner ring 2, and the shape of described lining inner ring 2 is cylindrical; Be distributed with the groove 3 of some rectangles at the circumference of cylindrical inner ring 2.
As shown in Figure 7, bulking machine anti-wearing liner of the present utility model comprises outer ring 1 and inner ring 2, and the shape of described lining inner ring 2 is cylindrical; Be distributed with the groove 3 of some arcs on the circumference of described cylindrical inner ring 2.
The groove 3 of above-described rectangle or arc is 5～20.
As accompanying drawing 5 and shown in Figure 6, be that the lining inner ring 2 of prior art is smooth form.
The course of work of bulking machine:
Material enters feeder from feed bin, under VFC, enter quality-adjusting device, in quality-adjusting device, steam enters material by multi-point injection, and under the double-shaft paddle stirring action, in quality-adjusting device, move back and forth, fully contact with material and damp and hot exchange takes place, promote temperature of charge and moisture, make the softening and precuring of material, material after modified enters extrusion mechanism by the gravity effect, with machine tube inner wall and augering screw fricting shearing, material extruding force in the process that advances is constantly strengthened, the gas of material is discharged from, and filled by material rapidly, material is subjected to the shearing force effect and produces backflow, pressure in the machine thorax is increased, continuous variation along with spiral and machine thorax gap, the size of friction is also little by little strengthening, material is fully mixed, extruding, heating, glue together final gelatinization and produce the tissue variation, original structure is damaged, mechanical energy is converted into heat energy by the friction effect of material in Builking cavity simultaneously, material is become have the gelatinized of flowing property, when material enters the last discharge end of screw rod, because to have adopted inner ring 2 are conical anti-wearing liners to the utility model or adopted the anti-wearing liner that has the groove 3 of some rectangles or arc at the circumference of inner ring 2, the anti-wearing liner that this inner ring changes has played the effect that slows down discharging opening pressure, make material be extruded to when outlet pressure and become normal pressure by high pressure moment, become normal temperature by high temperature moment.
