Description

Technical Field

[0001] The invention relates to the technical field of cake production, in particular to a cake production line and a production process thereof. Background Art

[0002] Cakes are generally made in an oven, with eggs, sugar and wheat flour as the main raw materials; milk, juice, milk powder, spices, salad oil, water, shortening and baking powder as auxiliary materials; after stirring, mixing and baking, they are made into a sponge-like snack; the traditional cake production method usually involves a series of continuous steps such as mixing, shaping, baking and cooling the raw materials, and the whole process often needs to be completed on the same production line; but in the existing cake production line, during the baking process of the cake, the heat of the baking oven is transferred from the outside to the inside of the cake, and generally a long baking time is required, resulting in low production efficiency, too long production line and other problems; at the same time, the cake is located in the baking tray, and the bottom of the cake is in contact with the baking tray, which is easy to cause uneven heating and poor baking effect during the baking process; therefore, it is urgent to develop a cake production line and its production process that can split the cake for processing, greatly improve the production efficiency, shorten the baking time and the length of the production line. Summary of the invention

[0003] In order to overcome the shortcomings of the existing pastry production line, during the baking process of the pastry, the heat of the baking oven is transferred from the outside of the pastry to the inside of the pastry, and generally a long baking time is required, resulting in low production efficiency, too long production line and other problems; at the same time, the pastry is located in a baking tray, and the bottom of the pastry is in contact with the baking tray, which easily leads to uneven heating and poor baking effect during the baking process. The technical problem to be solved by the present invention is to provide a pastry production line and a production process thereof that can split the pastries for processing, greatly improves the production efficiency, and shortens the baking time and the length of the production line.

[0004] The present invention is achieved by the following specific technical means: A pastry production line comprises a baking oven, wherein a material inlet and a material outlet are respectively arranged at both ends of the baking oven; a material inlet conveyor belt is fixedly arranged at the material inlet of the baking oven; a material outlet conveyor belt is fixedly arranged at the material outlet of the baking oven; a rotary conveyor line is arranged in parallel at one side of the baking oven, one end of the rotary conveyor line is connected to the material inlet conveyor belt, and the other end is connected to the material outlet conveyor belt; a plurality of baking trays are arranged on the rotary conveyor line, and a plurality of grooves are evenly arranged at equal distances on the baking trays; A demoulding and unloading device for unloading the baked cakes in the baking tray is fixedly arranged at one end of the rotary conveyor line near the discharging conveyor belt; a unloading conveyor belt is also arranged on one side of the demoulding and unloading device; a cooling device is fixedly arranged on the unloading conveyor belt; a first grouting device is also fixedly arranged on the demoulding and unloading device on the rotary conveyor line near the feeding conveyor belt; a shaping oven is fixedly arranged on the first grouting device near the feeding conveyor belt; a second grouting device is fixedly arranged on the shaping oven near the feeding conveyor belt; a vibrating conveyor belt is fixedly arranged on the second grouting device near the static conveyor belt; a third grouting device is fixedly arranged on the vibrating conveyor belt near the feeding conveyor belt; a batter storage tank and a jam storage tank are also arranged on the side of the rotary conveyor line away from the baking oven; the batter storage tank is respectively connected to the first grouting device and the third grouting device through a first conveying pipe; and the jam storage tank is connected to the second grouting device through a second conveying pipe.

[0005] Furthermore, the shaping oven includes an oven main body, in which a first conveying line with both ends extending to the outside is fixedly arranged; a slide rail is also arranged above the first conveying line in the oven main body; a sliding plate is slidably arranged on the slide rail; a cylinder is fixedly arranged on the upper end of the sliding plate, and the cylinder telescopic rod passes through the sliding plate and extends to the bottom of the sliding plate; a pressing plate fixedly connected to the cylinder telescopic rod is arranged on the lower side of the sliding plate; and an electric heating plate is fixedly installed on the lower side of the pressing plate.

[0006] Furthermore, the vibration conveyor belt includes a fixed box body; a second conveyor belt is arranged above the fixed box body, and the second conveyor belt is connected to the fixed box body through a buffer connector; a vibration motor is also fixedly connected to one side of the second conveyor belt.

[0007] Furthermore, a sensor is fixedly installed on the upper end of the oven body close to the first grouting equipment; the sensor detects whether a baking tray enters the shaping oven, and cooperates with the hot pressing structure in the oven body to hot-press and bake the dough in the baking tray.

[0008] Furthermore, a protrusion matching the groove of the baking tray is arranged on the lower end surface of the electric heating plate; the dough in the groove of the baking tray is hot-pressed and baked by the arranged protrusion, thereby forming a pastry base with an open groove at the upper end.

[0009] A cake production process comprises the following steps: Step 1: one-time grouting: injecting a certain amount of batter into a plurality of grooves provided on the baking tray through a first grouting device; Step 2: hot pressing and baking; hot pressing and baking the batter in the groove of the baking tray in a shaping oven to form a pastry base with an open groove at the upper end; Step 3: injecting jam filling; injecting a certain amount of jam into the opening groove of the pastry base in the baking tray through the second injection device; Step 4: Vibration and flattening: The jam in the opening groove of the pastry base is vibrated and flattened by a vibrating conveyor belt; Step 5: Secondary grouting: inject a certain amount of batter into the groove of the baking tray through the third grouting device to cover the pastry base and the jam in the opening groove of the pastry base; Step 6: Baking and forming; baking the batter on the upper part of the baking tray groove in a baking oven to form a pastry upper bottom connected to the pastry base; Step 7: De-molding and cooling: Take out the cakes in the groove of the baking tray through the demoulding and unloading setting, and convey them to the cooling equipment for cooling through the unloading conveyor belt.

[0010] Furthermore, after the jam in the open groove of the cake base is vibrated and flattened, the top surface of the upper end of the jam is not higher than the top surface of the upper end of the cake base, preventing the jam from overflowing from the open groove of the cake base.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The invention can split and process the cakes, greatly improve the production efficiency, and shorten the baking time and the length of the production line.

[0012] The pastry is divided into a pastry base, a jam filling and a pastry bottom, which are processed separately; first, the pastry base is processed through a shaping oven, and the processed pastry base can be eaten directly without considering the subsequent baking and heating issues; then, the jam filling is injected into the pastry base, and the jam filling can be eaten directly without being baked or heated; finally, batter is injected onto the pastry base and the jam filling; the uppermost batter is baked through a baking oven to form a pastry bottom connected to the pastry base, without the need for long-term baking; thus, the baking efficiency is improved, the baking time is shortened, and the length of the production line is shortened.
