Abstract

The utility model relates to the category of feed bulking machinery, in particular to a cotton seed bulking machine, which is mainly composed of an inlet magazine (7), an outlet spout (6), a shell (3), an extruding screw (2), and an extrusion head (5). The utility model is characterized in that the inner wall of the shell (3) is processed with spiral grooves (8), wherein the spiral directions of the spiral grooves are opposite to that of the extruding screw (2), and the spiral grooves (8) are in different depths which gradually decrease from the inner to the outer. The diameter of the feed-outlet spout is 2-2.5 times of the conventional similar bulking machine with dry processing. The utility model has the advantages that the bulking machine is not only capable of bulking cotton seeds successfully, but also bulking oil materials such as soy beans and the like, the squeezing temperature can reach 145 DEG C, thereby flaming and charring of cotton seed fuzz. The utility model is simple in structure, low in costs, high in efficiency, and great in product quality.

Description

Cottonseed sweller

Technical field

The utility model relates to the feed extruder class, particularly relates to a kind of cottonseed sweller.

Background technology

Use the feed extruder of the expanded material of dry method generally all to adopt extruding and puffing technology in the market, its structure mainly is made up of cylindrical shell, extruding screw, extrusion head, feed hopper, discharging spout etc.In mandatory feeding procedure, material will advance in cylindrical shell, the frictional force that needs material and cylindrical shell is greater than the frictional force between material and the screw rod, therefore normally have straight trough,, play and strengthen shearing and the effect that helps extruding to increase the frictional force between material and cylinder inboard wall at the inwall of cylindrical shell, again because the extrusion of material requires certain temperature and pressure, so it is less that the discharging spout of bulking machine designs usually, is generally φ 4-8mm, to increase choked flow effect and cylinder internal pressure.When stating the expanded cottonseed of the bulking machine of structure in the use, because the discharging spout causes discharging speed slow for a short time, burning carbonate very easily under the HTHP of skin suede in cylindrical shell of cottonseed, stop up inner chamber, avoid the skin suede burning carbonate of cottonseed, then discharging speed need be accelerated, the diameter of discharging spout will be increased.But to only increase the size of discharging spout, then can reduce choked flow effect and cylinder internal pressure, can't reach the desired pressure of extrusion, temperature, influence expansion effect.Therefore use the dry production can't expanded cottonseed with the bulking machine of this structure.

Summary of the invention

The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of cottonseed sweller that is used for dry production is provided, this machine can expanded cottonseed, again can expanded soybean etc. lipid material, this machine has improved extrusion shearing power and crowded thrust greatly, has increased the discharging nozzle diameter simultaneously, and discharging speed is very fast, solved the technical barrier that stops up inner chamber, and expanded cottonseed effect is fine.

The utility model purpose realizes being finished by following technical scheme:

The utility model mainly is made up of feed hopper (7), discharging spout (6), cylindrical shell (3), extruding screw (2), extrusion head (5), it is characterized in that on the inwall of cylindrical shell (3), being processed with helicla flute (8), this spiral fluted rotation direction is opposite with the rotation direction of extruding screw (2), and the degree of depth of helicla flute (8) differs, and the degree of depth reduces from inside to outside gradually.The diameter of discharging spout is 2-2.4 a times of existing dry method bulking machine of the same type.

The utility model has the advantages that, can the success expanded cottonseed, extrusion temperature can reach more than 145 ℃, can avoid the skin suede burning carbonate of cottonseed, simple in structure, cost is low, efficient height, the good product quality of being produced.

The expanded cottonseed product that uses the utility model to produce, after testing: the cotton seed puffing detoxification efficiency reaches more than 50%; Rise to 21% after cottonseed 12.2% degradable albumen is expanded; Crude protein rises to 25% from 20%.

But the utility model is a tractor serves several purposes also, the full-fat extruded soybean that uses the utility model to produce, and its uremic enzymatic activity is at 0.01-0.02, and crude protein is more than 40%.And the expanded soybean that present commercially available bulking machine is produced, its uremic enzymatic activity is at 0.05-0.2.As seen it greatly reduces the content of ANFs, has improved the quality of full-fat bean.

Summary of drawings

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model cylindrical shell cutaway view;

Concrete technical scheme

The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:

As shown in Figure 1, 2, label 1-11 represents respectively: the feeding section (10) of turning cylinder (1), extruding screw (2), cylindrical shell (3), cover plate (4), extrusion head (5), discharging nozzle (6), feed hopper (7), helicla flute (8), feed screw (9), helicla flute (8), the extruded segment (11) of helicla flute (8).

The utility model mainly is made up of feed hopper (7), discharging spout (6), cylindrical shell (3), extruding screw (2), extrusion head (5), it is characterized in that on the inwall of cylindrical shell (3), being processed with two spiral shell head helicla flutes (8), this spiral fluted rotation direction is opposite with the rotation direction of extruding screw (2), and the degree of depth of helicla flute (8) differs, and the degree of depth reduces from inside to outside gradually.The feeding section (10) of helicla flute (8) is the single head spiral, and extruded segment (11) is a twin-feed spiral.The diameter of discharging spout is 2 times of existing dry method bulking machine of the same type.

The utility model in use, after material flows into automatically from feed hopper (7), under the promotion of feed screw (8), enter between the helicla flute (8) that the degree of depth is gradually little on extruding screw (2) and the cylindrical shell, be subjected to abundant and high-intensity shearing, kneading, extruding, along with material continues to advance, the friction self-heating constantly raises temperature, pressure continues to increase to expanded required pressure and temp, and at this moment material is in the moment that the discharging spout is discharged, pressure release suddenly and expanded rapidly.

Though below design and embodiment according to the utility model purpose are described in detail with reference to accompanying drawing, but those of ordinary skills can recognize, under the precondition that does not break away from the claim limited range, still can make various improvement and conversion to the utility model.
