According to the design, the complete agitating shaft is characterized by comprising an excircle-changing spiral body (shown as a figure 6) consisting of two excircle-changing spiral strips, two scrapers (shown as a figure 5) with intermittent edges, and an eccentric shaft (shown as a figure 7) with a spiral blade, wherein the two scrapers are staggered with one edge in the 180-degree direction on the spiral periphery of the spiral body of the agitating shaft, so that the intermittent edges are staggered; and the spiral direction of the spiral blade is opposite to that of the spiral body. The design can meet the design requirements of the agitating shaft of the soft ice cream machine (especially a small soft ice cream machine) on efficient heat exchange, full agitation, stable running and powerful material pushing and feeding.
Description
Technical field:
The invention belongs to food machinery industry, relate to the design and manufacturing technology of the shaft of soft ice-cream machine in ice cream machinery.
Technical background:
Shaft (being also referred to as agitator or screw feeder in industry) is the critical component of ice cream equipment, ice-cream important quality index-----expansion rate, sophistication, anti-melting property (higher expansion rate and good sophistication can significantly improve ice-cream anti-melting property) all with the vital relation of being designed with of shaft.Especially for soft ice-cream machine, the speed of producing, every part of ice-cream continuity, all relevant with the design of shaft.Due to the discharging thrust of soft ice-cream machine come in shaft, therefore the shaft of soft ice-cream machine structurally all has the structure of helical feed.The design comparison maturation of the shaft of existing soft ice-cream machine have following two large classes:
1 nylon shaft (see figure 1), this technology is injection molded into shaft the conveyor screw of a nylon, and this conveyor screw plays the effect of stirring and pusher.
Advantage: simple in structure, cost is low.
Shortcoming: heat transfer effect is poor, expansion rate and sophistication are all poor, and the characteristic of the rising-heat contracting-cold of nylon easily causes mechanical breakdown.This technology is applied more in common soft ice-cream machine.
2 have eccentric shaft, and (effect of eccentric shaft is: eccentric shaft is fixing non-rotary by screw propulsion bar and in the middle of spiral bar, in spiral bar rotary course, increase mixing power) shaft, because main body is that stainless steel material is made, so be also referred to as metal shaft in industry.The design of metal shaft has following several types at present:
(1) metal shaft with scraper, this design has been installed a blade in the middle of a lead of screw of spiral bar, on longer shaft, can 180 degree misorientations be installed by second blade (see figure 2).
Advantage: scraper is that the barrel of being close to refrigeration cylinder is walked in shaft rotary course, and the effect of heat exchange is best, has the shaft of scraper can farthest improve expansion rate and the sophistication of ice-cream product.
Shortcoming: because scraper has certain width, the back of on-stream scraper can produce the vacuum band of a slurry, virtually can reduce the heat exchange area of refrigeration cylinder and slurry, in order not reduce the heat transfer effect of refrigeration, therefore on a periphery, generally design one blade, cause therefrom the operation of shaft not steady, when especially ice cream is really up to the mark, easily cause machine breakdown.Blade easily weares and teares, and the cost of manufacturing in addition spiral bar is higher.
(2) shaft of embedding nylon strip, the spiral bar that this is designed with two strip metals, is symmetric, and is embedded with special nylon filler rod in spiral bar outside, and this filler rod is close to the barrel of refrigeration cylinder, plays the effect (see figure 3) of scraper.
Advantage: have good effect of heat exchange, ice-cream expansion rate is high, and sophistication is good, smooth running.
Shortcoming: filler rod is gapped in the closely sealed middle meeting of spiral bar, this gap is unfavorable for cleaning, and causes health concerns; Filler rod after the wearing and tearing difficulty that changes the outfit is larger, needs professional to implement.
(3) shaft of pure spiral bar, this design is by two symmetrical metal spiral bars, and directly rotation in refrigeration cylinder, by controlling the spirochetal cylindrical of two spiral bar compositions and the precision of refrigeration cylinder inner circle, has also reached the effect of scraper to a certain extent.
Advantage: ice-cream expansion rate is high, sophistication is good, and smooth running does not have the problem of blade wears.Long service life.
Shortcoming: because not being is close to refrigeration barrel, shaft and refrigeration cylinder inwall have certain gap, form on cylinder inwall and have one deck ice-cream " thermal isolation film ", and heat transfer effect is general; Manufacture installation accuracy is had relatively high expectations, once revolute wearing and tearing all can cause large infringement to shaft and refrigeration cylinder.
The eccentric shaft design using in all existing metal shafts is direct-rod type and ring-like or the two combination (see figure 4).
Summary of the invention
The object of the invention is the design of the shaft in order to seek a kind of soft ice-cream machine, this design need to retain and expand existing soft ice-cream machine shaft advantage, abandons the shortcoming of existing shaft.Especially for small-sized soft ice-cream machine, the length of its refrigeration cylinder is short, and conveyor screw is also short, is just revealed as thrust inadequate after ice cream condenses.With the inadequate problem of thrust that solves small-sized soft ice-cream machine, solution of the present invention is in order to achieve the above object:
A kind of design of shaft of soft ice-cream machine
It is characterized in that: 1 one of the design scraper (see figure 5) of being interrupted sword, on shaft, blade of 180 degree direction dislocation installs two this scraper; 2 one of design become the spiral bar of cylindrical, and two are symmetrically formed a conveyor screw (see figure 6) that becomes cylindrical.Design an eccentric shaft (see figure 7) with helical blade.
Designing technique of the present invention has the following advantages:
The scraper of 1 two interruption swords can reduce the minimizing of scraper heat exchanging area to greatest extent, can solve again the stationarity problem of a slice scraper, the abundant stirring of slurry is had to castering action simultaneously.
Article 2 two, the conveyor screw that becomes the spiral bar composition of cylindrical has been created condition into installing two scraper, and the discharging thrust of shaft is maximized.In the situation that shaft length is definite, the helical pitch of the spiral bar high thrust that heals is less, become the design of cylindrical and make installing two scraper in the situation that, the helical pitch of spiral bar minimizes, and namely in actual use, thrust maximizes (this is particularly important to small-sized soft ice-cream machine).
3 eccentric shafts with blade be also for small-sized soft ice-cream machine custom-designed.Use spirochetal revolving force, the eccentric helical blade maintaining static had not only played to increase the effect of mixing power but also play has increased the thrust of ice cream material (hand of spiral of the helical blade of eccentric shaft is contrary with the spirochetal hand of spiral).
