Description

[0001] The present invention relates to a 3D food printer for producing a food product based on a cream,

The present invention relates to a 3D food printer and a 3D food printing method for producing foods containing cream as a main ingredient. And more particularly, to an ice cream production apparatus using a 3D printer.

The 3D printer is a device that produces a three-dimensional object by sequentially spraying a special material and accumulating a layer with a fine thickness. Recently, the 3D printer has been widely used in various fields.

Various 3D printers have been developed and used with the proliferation of such 3D printers, and they are classified into FDM (lamination method), SLS (powder sintering), SLA and DLP (liquid resin) do.

First of all, the FDM method is the most widely applied method, and the 3D printer stacks materials in a stacking manner. The 3D printer extrudes the material thinly as a thread and sequentially stacks the shapes one by one to output a product.

Typically, the material (filament) applied to the FDM-type 3D printer is a PLA (polylactic acid) material and an ABS (acrylonitrile poly-butadiene styrene) material.

In addition, there have been recent attempts to manufacture chocolate, ice cream, and latte art with such 3D printers.

In general, latte art means to draw a variety of paintings on coffee to satisfy consumers' needs at coffee shops and coffee shops.

Such latte art is not easy, and coffee drink makers are mainly engaged in it, and many people practice it. However, it is difficult to make a large amount due to time and manpower constraints, and it is difficult to make a precise shape.

Also, in general, ice cream is mainly produced in large quantities by ice cream makers, packed in units, and then sold to consumers. Since the ice cream maker must produce a large amount of ice cream, it is equipped with an ice cream automation manufacturing facility that mass-manufactures ice cream, and then mass-produces ice cream from the ice cream automation manufacturing facility.

Such an ice cream automation manufacturing facility takes a long time because it manufactures ice cream through various steps, and it requires a large-scale facility, so that it takes a lot of cost to equip the facility. In addition, there are limitations in producing various types of ice cream and ice cream of various sizes to meet the taste of consumers.

An instant ice cream maker is disclosed in Korean Patent No. 10-1066402 (registered on September 15, 2011) (hereinafter referred to as prior art). The prior art is capable of instantly manufacturing a variety of ice creams desired by the user to enjoy ice cream but rotating the hopper containing raw materials of ice cream or ice cream and supplying the liquid nitrogen to the hopper from the outside while rotating the agitator in the raw materials filled in the hopper The liquid nitrogen is not effectively supplied to the raw material filled in the hopper, so that the time for making the ice cream is delayed and the liquid nitrogen is consumed. Further, the configuration is complicated, making it inconvenient for the user to operate.

In addition, such existing ice cream makers have limitations in that users and consumers can not manufacture ice cream in a desired form.

Accordingly, there is an urgent need to develop a food print technology capable of satisfying an increasing consumer's desire and printing a desired image uniformly and clearly.
