Description
Technical field
The utility model is related to a kind of feed production equipment more particularly to a kind of expanded feed equipment pressure-regulating devices.
Background technology
Feed extruder is widely used to field of food and field of feed processing.Puffing is to adjust material humidification, heating
Matter processing, and squeeze out die hole or spray pressure vessel suddenly, the technological operation of enlarged volume is made because being depressured suddenly.Extrusion
Technology is widely used to field of food and field of feed processing.In the prior art, various rule of high gelatinization degree in order to obtain
The Extrusion Products of lattice size, different densities allow material to be carried out using water and steam by quality-adjusting device quenched first, and material exists
Infiltration is adequately contacted with water, steam in quality-adjusting device, by the regular hour, material obtains certain pre-gelatinized, after pre-gelatinized
Material enter back into screw extruder and squeezed.When extruder works, by the material of certain precuring by that can revolve
The screw rod turned is moved to discharging die hole direction, and in material in from feed inlet to discharging this section of distance of die hole, material is in extruder
By being acted on by powerful mechanical energy when rotatable screw rod, temperature, the pressure of material are gradually promoted, and are discharged when material reaches
Before die hole, the gelatinization degree of material reaches highest state, and subsequent material is squeezed out from discharging die hole, then obtains height by cutting
The extruding grain products of gelatinization degree.Make material physical property that the variation of matter occur using puffing technique, greatly improves feed product product
Matter has expanded feed resource, improves the digestibility of feeding feed stuff, and puffing technique is effectively preventing animal alimentary canal diseases
And there is unique advantage in terms of feed safety.Under high temperature, high pressure conditions through strong extruding, shearing, friction, mixing, squeeze
It sends as an envoy to starch gelatinization in feed, albuminous degeneration, each component between material generates strong physics and physicochemical change, object
Material all produces the big variation of tool on macro-and micro-structure.Feed has through high temperature, high pressure in extruding reaction device high simultaneously
Moisture enables the activity of various anti-nutritional factors to obtain more effectively being passivated, harmful levels of pathogens is compared with can thoroughly inactivate.To make to squeeze
Press the finished product of bulking machine has good water resistance and stability, easy to digest, absorption efficiency is high, bacteria containing rate is low, safety is good etc.
Feature.But bulking machine, in carrying out puffing process, material can be moved with the rotation of screw rod in screw sleeve, due to spiral shell
The variation of the depth of thread on bar, can be such that the pressure suffered by material is constantly increasing, and in this process, screw sleeve easily goes out
Now block and puffing set in the excessively high problem of temperature；Moreover, the quality of puffing quality, it is important to the pressure in machine barrel and temperature
Degree, different types of material need the expansion effect that different pressure can be only achieved, and the size of pressure is mainly by machine barrel and spiral shell
Gap between bar determines.The bulking machine pressurizing unit of the prior art, is primarily present following disadvantage：It can not be according to the kind of material
Class adjusts the pressure in machine barrel, influences expansion effect.Especially in puffing straw feed, due to the main chemistry of straw feed
Ingredient is the cellulose of lignifying and non-woodization, hemicellulose, and pressure is more difficult to control, and is blocked in puffing machine barrel or stifled
Fill in mold.
Utility model content
The utility model is to be directed to deficiency of the prior art, and provide a kind of simple structure and reasonable design, real
The quantitative adjusting to the in-house maximum pressure of screw extrusion is showed, when pressure is excessive, can expand aperture prevents from blocking
With release stress；Again aperture can be reduced so that a kind of guaranteed expanded feed of the puffing quality of feed when pressure is reduced
Equipment pressure-regulating device.
To achieve the goals above, the utility model provides the disk body with die hole, and corresponding die hole is provided with aperture
Pressure sensitive regulating device, so as to according to pressure adjust aperture size, so that excessive pressure is comparatively fast discharged, but pressure not
When sufficient, aperture is reduced so that the puffing quality of feed is guaranteed.The pressure of aperture pressure sensitive regulating device adjust mainly by
The aperture adjusting block that spring and spring push is completed, since spring is with the directly proportional characteristic of deformation and pressure, thus in pressure
When bigger, aperture is bigger；When pressure is reduced, aperture reduces, to can not only put into practice the qualitative adjustment of aperture and pressure, and
The quantitative adjusting relationship between pressure and aperture may be implemented completely.
