Description

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a technical field of food processing, and more particularly to a bun machine.

2. Description of Related Arts

The conventional bun machine is only able to filling a single layer of fermented dough with fillings for producing a bun. The bun may be fried or steamed. However, disadvantages of the bun produced by the conventional bun machine are as follows. Firstly, the fermented dough is soft. As a result, during producing or cooking, the bun is likely to be broken, which lowers quality and appearance of the bun. Secondly, the fermented dough has a lot of holes which absorb juice of the fillings. Therefore, taste of the bun is badly affected.

SUMMARY OF THE PRESENT INVENTION

An object of the present invention is to provide a bun machine for producing a bun with a fermented dough outer layer and an unfermented dough inner layer.

Another object of the present invention is to provide a bun machine for producing a bun which is not easy to be broken and is able to keep juice of fillings inside the bun for a long time.

Accordingly, in order to accomplish the above objects, the present invention provides a bun machine, comprising:

• • a pressing device, comprising: a first tank for storing and inputting a fermented dough into the pressing device; a second tank for storing and inputting an unfermented dough into the pressing device; a first presser pressing the fermented dough inputted through the first tank for forming a first layer; a second presser pressing the unfermented dough inputted through the second tank for forming a second layer; a first outlet for outputting the first layer; and a second outlet for outputting the inner layer;
  • an overlaying device, comprising: a first transporter for transporting the first layer outputted from the first outlet; and a second transporter for transporting the second layer outputted from the second outlet; wherein a first end of the first transporter is connected to the first outlet, a first end of the second transporter is connected to the second outlet; a first transporting speed of the first transporter equals to a second transporting speed of the second transporter, and a second end of the second transporter is above the first transporter, in such a manner that the second layer drops to and overlays the first layer for forming a bun crust; a second end of the first transporter outputs the bun crust;
  • a main transporter, wherein a first end of the main transporter is connected to the overlaying device for transporting the bun crust;
  • a feeding device provided aside the main transporter, comprising: a filling tank for storing and inputting fillings into the feeding device; and a feeding unit feeding the fillings onto the bun crust;
  • a wrapping device provided above the main transporter, wherein the wrapping device wraps the fillings with the bun crust for forming a filled roll; said wrapping device forms an opening with said main transporter, in such a manner that said filled roller is still transported by said main transporter; and
  • a separating device connected to a second end of the main transporter, wherein the separating device squeezes the filled roll for separating and sealing the filled roll, so as to produce buns.

With the foregoing structure, the bun machine is able to produce a bun with two dough layers. An inner layer of the bun is made of the unfermented dough, and an outer layer of the bun is made of the fermented dough. Therefore, compared with a bun produced by a conventional bun machine, the bun produced by the bun machine according to the present invention is not easy to be broken and is able to keep juice of fillings inside the bun for a long time.
