Description

Temperature control system of extruder multistage screw rod with additional distributing and converging functions

Technical field

The present invention relates to a kind of multi-stage screw temperature control system, particularly a kind of temperature control system of extruder multistage screw rod with additional distributing and converging functions.

Background technology

Along with increase day by day to the requirement of the nutrition of food, the bread basket and the production method thereof of various composite nutrients are also developing by leaps and bounds, from the pre-steaming method technology of early stage acid, directly soak technologies such as suction method and coating method, develop into nowadays more complete:, obtain the technological process of multi-nutrient fortification composite cereal at last from cereal pulverizing → preliminary treatment → mix with nutrient → push → excision forming → drying → screening → join rice in proportion.

And the step of extruding-excision forming wherein is the important step in the production process, single screw rod or the twin (double) screw extruder generally taked, the hydrate of cereal powder is pushed the back by certain shape mould, obtain the cereals of needed shape, size through cutting, and on corresponding conveyer belt, carry, until check and packaging step.

Simultaneously, because the techniqueflow of extrusion modling process can be processed into cereal the product with certain puffed degree and mellowness, be applicable to products such as various food, nourishing additive agent, animal feed.

International open text WO01/72151 discloses a kind of incorporate composite cereal mixing, extruding, former.Comprise raw material blending device, twin (double) screw extruder, extrusion device, excision forming equipment.Raw material blending device wherein and twin (double) screw extruder link to each other by the vertical transport pipeline that is communicated with, and be provided with control valve in pipelines, to adjust speed and the product efficiency that the premix raw material enters extruder.Be arranged in parallel in the twin (double) screw extruder screw rod of two mutual interlocks of screw thread rotates in opposite directions, makes the material of from top to bottom carrying can carry out compacting fully and conveying.End at extruder has extrusion dish, offer a plurality of extrusion cavities on the extrusion dish, be close to the extrusion cavities place and be provided with cutter sweep, the strip-shaped materials that squeezes out can be cut into needed strip, granular or sheet products, to meet the needs of various cereal joint products.

U.S. Pat 5350585 discloses a kind of double-screw structure of extruder.Described double-screw structure is divided into multistage, and its thread density is all inconsistent, to cooperate the needs in each stage in the extrusion process.Simultaneously, also offer the cavity in the screw rod, so that material fully mixes in screw extruder.

Yet traditional screw rod extruding excision forming machine still has some shortcomings:

1, the product that obtains of traditional extruding cutting equipment directly carries out the heating, drying step, yet but tends in baking step and since the product that contains moisture suddenly dehydration cause product surface to break or pulverize, cause the yield rate reduction.

2, the output of traditional extrusion formation equipment and productive rate are difficult to be greatly improved.

3, the screw rod of traditional screw extruder directly is positioned in the cavity of ellipse or circular cross-section, and in extruding and the course of conveying, material is easy to pile up in some position generation, thereby squeezing effect is reduced again.

4, packing phenomenon is often arranged in the screw rod cavity, and these deposits of failing for a long time fully to be pushed can condense into piece after after a while, thereby influence the uniformity coefficient of integral product output efficiency and product, need often cleaning.Yet the screw rod of traditional twin (double) screw extruder is changed the process difficulty, and after shutting down, screw rod still can produce mechanical rotation because of the structure of mutual interlock, causes the accident easily.

5, last, in the process of preparation reconstituted rice, gelatine can take place in the material that water and ground rice mix under heating condition, existing conventional extruder not only can't produce suitable gelatine degree also can't solve the problem that material viscosity that gelatine brings increases, yet the control heating-up temperature that existing extruder can't be good, control gelatine degree.
