Description

A kind of double-colored or extra quality bulking machine

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of food processing machinery, particularly a kind of bulking machine that carries out extra quality or double-colored food processing.

Background technology

Bulking machine belongs to a kind of equipment of processing dilated food, such as the rice in processing daily life, corn, soybean, wheat etc., its main operation principle is exactly that mechanical energy is transformed into heat energy, the heat producing in the time of by machine turns is ripe by food extrusion, through the expanded the most obvious feature of food, is exactly that volume becomes greatly.The process of single serew bulker is: need the raw material of expanding processing to send in Builking cavity by import, the raw material that contains a certain amount of moisture content under the impetus of screw rod with extruder member in screw rod, expanded cavity produce the effects such as friction, shearing, and in Builking cavity, form HTHP, the discharging nib that raw material is forced to template is extruded, due to the pressure reduction inside and outside chamber, thereby raw material is sharply expanded, occur expanded.According to the difference of process principle, bulking machine can be divided into cereal expanding machine, flour bulking machine and soybean puffing machine etc., and they all can only realize single expanding processing of planting raw material.

Along with the raising of people's living standard, people are also more and more higher to the requirement of dilated food.People not only have requirement to the mouthfeel of dilated food now, and the color and style for dilated food has pursuit too, therefore the dilated food of monochrome or single port taste or thin material can not meet people's requirement, designs a kind of double-colored or extra quality bulking machine is just very necessary.Chinese patent [authorizing publication No.: CN102389155A] discloses a kind of twin-screw extruder that carries out double-colored dilated food production, and it comprises termination, and termination comprises die head, machine barrel and two screw rods; Two screw rods are engaged with each other and are arranged in machine barrel; The diameter of screw rod tail end reduces gradually, makes screw rod tail end be coniform; Die head is arranged on the end of machine barrel, has nib on die head; In two out-of-gear regions of screw rod, the side of machine barrel is provided with two colors and adds mouth.This utility model can be produced desirable double-colored decorative pattern dilated food by adding pigment, processing when but this utility model but cannot realize two kinds of raw materials of different nature, and the dilated food that this utility model is produced is owing to stirring and pushing in same chamber, pigment tends to interpenetrate and causes appearance not good.

Summary of the invention

The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of double-colored or extra quality bulking machine, and it can be processed and make it two kinds of different colours or raw material of different nature and combine, thereby processes double-colored dilated food.

The purpose of this utility model can realize by following technical proposal: a kind of double-colored or extra quality bulking machine, comprise frame, be arranged on the motor in frame, main body, feeding mechanism and discharging mechanism, it is characterized in that, in described main body, there is two horizontally sets separate Builking cavity, in described Builking cavity, be respectively equipped with an extruding screw, described extruding screw is driven by motor, described feeding mechanism comprises two separate feed hoppers, two feed hoppers are connected with two Builking cavities respectively, described discharging mechanism is arranged on the front end of main body, described discharging mechanism has two imports and while and above-mentioned two discharging openings that import is connected, described two imports are connected with two Builking cavities respectively.

During the utility model work, feeding mechanism can be poured into the raw material of two kinds of colors or two kinds of character respectively in two separate Builking cavities by two feed hoppers, and by extruding screw, undertaken by a discharging opening, extruding after expanding treatment respectively, thereby make the dilated food of extruding can present two kinds of colors, visual effect is better, and appearance is better; Or two kinds of raw materials of different nature are mixed, and taste is better.

In above-mentioned double-colored or extra quality bulking machine, described discharging mechanism comprises and is arranged on main body front end mutual stacked gather materials plate and template, described two imports are made as that being arranged on gathers materials runs through type through hole on plate rear end face, on the front end face of the described plate that gathers materials, there are two grooves that are connected with two imports respectively, in described template, be embedded with a material discharging module, described discharging opening is arranged on material discharging module and can be connected with two grooves simultaneously.Plate and the template of gathering materials stacks together by bolt assembly one is closely connected, discharging opening is located on the center of template, the discharging opening position of two Builking cavities is positioned at the edge of the plate that gathers materials, two imports are connected with two Builking cavities or sleeve respectively, two grooves are arranged in the radial position of the front edge of board face that gathers materials and are positioned on same diameter, the center of the plate that gathers materials that the raw material of being drawn by two Builking cavities can be led with prestissimo, and extrude by discharging opening, avoid cooling too fast and affect expansion effect.

In above-mentioned double-colored or extra quality bulking machine, the rear end face of described material discharging module has a circular-shaped, concave cavity that can be connected with two grooves simultaneously, described discharging opening is for several through-hole structure that circumference uniform distribution is arranged on material discharging module and laterally runs through material discharging module, and described discharging opening is connected with cavity.Two hole raw materials out that gather materials by the plate that gathers materials are joined in cavity, and extrude by through hole, because two groups of bulked structures of this bulking machine are all identical, the raw material mutual nonaggression of two kinds of colors or two kinds of character in cavity, but each through hole that is freely positioned at its corresponding side is extruded, and be finally gathered together the dilated food that forms two kinds of colors.

In above-mentioned double-colored or extra quality bulking machine, the front end face center of described material discharging module has a protruding cylindrical mould post forward, the outer wall of described mould post has two symmetrically arranged excessive platforms, and described two excessive platforms are separately positioned on top and the bottom of mould post.The mould post that the center of material discharging module has can be so that the food of being extruded by discharging opening becomes circular tube shaped, but the materials variances due to two kinds of colors or two kinds of character raw materials, the joint portion of two kinds of raw materials is often relatively thin, easily ftracture, the utility model arranges the excessive platform radially perpendicular with mould post on the position corresponding to two kinds of raw material joint portions, two excessive platforms are with respect to whole mould post edge indent, because two excessive platforms are separately positioned on the place that converges of two kinds of colors being positioned on mould column top and bottom or two kinds of character raw materials, the raw material converging on transition bench can be locational more compared with other, thereby can guarantee the better of two kinds of colors or the combination of two kinds of character raw materials, avoid because nature difference causes joint portion problem easy to crack.
