A kind of feeding device of the detachable chocolate 3D printer with function of temperature control
Technical field
This utility model is related to a kind of food processing field, more particularly to a kind of detachable chocolate with function of temperature control
The feeding device of 3D printer.
Background technology
3D printing increases material manufacturing technology follows the know-why of " multi-shell curing is added up layer by layer ", Aero-Space, automobile,
The field such as mould and biologic medical has broad application prospects.At the same time, by food service industry manufacture and 3D Intelligent printing skills
Art combines, and is beneficial to promote the new development of food industry, is conducive to lifting the technical merit and product water of food industry
It is flat.
One of food service industry represented with chocolate possesses nearly hundred billion market space in China.With the overall income of residents
Raising, people are for the demand more and more higher of the personalized chocolate food of any style.One of advantage of 3D printing is exactly
Be particularly good at personalized customization, can quickly manufacture personalized chocolate pattern, greatly reduce personalization, customized production and innovation
The traditional processing cost of design.
Can whether chocolate 3D printer be easy to clean and realize that effective temperature control becomes printing bottleneck problem,
Adopting syringe formula at present chocolate printer equipment, principle is to drive piston press to go out chalk by increasing pin overpressure more
Power solution, realizes chocolate in three-dimensional printing.But reload and be generally inconvenient to, every time can only syringe capacity size squeeze
Go out, print routine to be interrupted, cause operation inconvenience.And its heater is copper heating tube(Such as Chinese patent
ZL201420060258.6), using resistance heating rod heated chocolate syringe, temperature rising is too fast, and unstable, chocolate exists
Directly it is extruded in syringe, molding is bad, in addition using syringe formula chocolate extrusion way, chocolate is also easy to produce wriggling
Phenomenon, molding are unstable.And screw rod is applied in barrel using the 3D printing equipment of screw extruding head(Chinese patent
ZL201310606370.5), its inner chamber storage of raw materials need to will pass through screw rod therein and remove during cleaning barrel, and cleaning is inconvenient.
Further, since screw rod is applied in barrel, in heating process, electric motor driven screw heating can affect the temperature of chocolate in barrel
Degree, makes temperature control unstable.
Therefore, how a kind of feeding device of effective temperature control is provided, and material storage tube is easy to clean, is those skilled in the art
Problem anxious to be resolved at present.
