Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and more specifically to an oven for pastry production. Background Technology

[0002] Existing ovens for pastries generally have multiple support racks fixed inside. The baking tray containing the pastry ingredients needs to be placed on the support racks in the oven for baking. Since the support racks and other parts cannot be removed, it is very troublesome to clean them after a period of use.

[0003] Secondly, existing ovens need to dissipate heat after baking. However, due to the oven's airtight design, the door can only be opened for heat dissipation, which is ineffective. Opening the door can also affect the movement of people around the oven, and external objects can easily enter the oven, affecting the hygiene of the pastries inside.

[0004] Secondly, if pastries are left in the oven for an extended period of time without being removed, they may spoil and require low-temperature insulation. However, current ovens do not have this function. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an oven for pastry production that can quickly dissipate heat and cool down the oven after baking pastries, and can achieve low-temperature preservation to ensure that the pastries inside are not easily spoiled.

[0006] The solution of the present invention to the aforementioned technical problem is:

[0007] An oven for pastry production, wherein the process of processing pastries using the oven includes the following steps:

[0008] (1) Place the pastries to be baked on a baking tray, place the baking tray on a rack, and move the rack into the oven;

[0009] (2) The wheels of the grill extend out of the bottom of the slot on the bottom plate of the oven;

[0010] (3) Press down the pressing plate of the pressing mechanism at the top of the oven to make the bottom plate of the rack drop down and cover the slot below, and then close the oven door;

[0011] (4) Press the control switch of the oven controller to heat the electric heating rods on both sides and turn on the circulating fan to achieve circulating baking;

[0012] (5) After baking, the ventilation control device on the ventilation pipe at the top of the oven will be activated to allow ventilation. The pressing plate of the pressing mechanism will return to its original position so that the bottom plate of the rack does not cover the slot. The electric heating rod will be turned off. At the same time, the circulating fan will continue to run to allow the internal hot air to be discharged and achieve cooling.

[0013] (6) The temperature sensor senses the temperature inside the oven. When it drops to room temperature, the pressing plate of the pressing mechanism presses down, causing the bottom plate of the rack to drop down and cover the slot below. The ventilation control device is activated, causing the ventilation pipe to be closed. The cooling system at the rear of the oven is activated, keeping the temperature inside the oven in a low-temperature state.

[0014] It includes an oven, the bottom plate of which is formed with at least two rearwardly extending slots in the middle, the front ends of which penetrate the front wall of the bottom plate of the oven, and the bottom of the oven bottom plate is equipped with casters with brakes on the front and rear left and right sides.

[0015] The oven has a side partition extending from front to back on the left side, which divides the oven into a left control cavity and a right main cavity.

[0054] All electrical components in this embodiment are electrically connected to the controller via electrical connection lines. The corresponding actions are achieved by operating the controller, which will not be described in detail here, and some parts are omitted in the accompanying drawings.

[0055] The rapid heating and cooling method for an oven in this embodiment includes the following steps:

[0056] 1. Place the pastries to be baked on the baking tray, and place the baking tray in the baking rack 20. The left and right sides of the baking tray should be on the top surface of the corresponding two support beams 25. After all the baking trays are installed, move the baking rack 20 into the oven 10. This method allows you to place all the pastries to be baked on the corresponding baking trays, place the baking trays on the baking rack 20, and then move them into the oven 10. It is easy to load and unload, and after a certain period of time, the baking rack 20 can be removed and cleaned. It is very convenient.

[0057] 2. The rollers 211 of the baking rack 20 extend out of the bottom end of the slot 11 on the bottom plate of the oven 10;

[0058] 3. The pressing plate 31 is pressed down onto the upper horizontal fixed plate 26 by the push rod of the electric cylinder 32 of the pressing mechanism 30 at the top of the oven 10, causing the bottom plate of the baking rack 20 to drop, the buffer spring 214 to compress, and the high temperature resistant bottom elastic sealing plate 23 to press against the top surface of the bottom plate of the oven 10 and cover the slot 11 below. Then, the door of the oven 10 is closed.

[0059] 4. Press the control switch of the oven 10 controller (which extends out of the corresponding position of the front wall panel of the oven 10) to heat the electric heating rods 1 on both sides and turn on the circulating fan 15 to achieve circulating baking.

[0060] 5. After baking, when rapid heat dissipation is required, the electric heating rod 1 stops heating, and the ventilation control device on the ventilation pipe 7 at the top of the oven 10 is activated. The push rod of the second electric cylinder 8 pushes the lifting sleeve 81 down, so that the lifting sleeve 81 does not cover the side passage groove 71. At this time, the rear heat exchange circulation chamber is connected to the outside through the top through hole 82 to achieve ventilation. At the same time, the push rod of the electric cylinder 32 of the pressing mechanism 30 retracts, and the pressing plate 31 returns to its original position, so that the slot 11 is not covered. The circulating fan 15 continues to run, so that the internal hot air is discharged to achieve cooling.

[0061] 6. The temperature sensor 3 senses the temperature inside the oven 10. When the temperature drops to room temperature, the pressing plate 31 of the pressing mechanism 30 presses down, causing the bottom plate of the rack 20 to drop and cover the slot 11 below. The ventilation control device operates, causing the lifting sleeve 81 to rise and cover the side passage 71 of the ventilation pipe 7. Then, the cooling system at the rear of the oven 10 operates, allowing cold air to enter the oven 10 and keep the temperature inside at a low temperature.

[0062] The cooling system operates on the same principle as existing refrigeration systems, so it will not be described in detail here.

[0063] The first circulation connector 9 is connected to the top plate of the rear cooling housing 80, and the second circulation connector 91 is connected to the top plate of the front oven cavity. The top of the first circulation connector 9 is connected to the outlet end of the electric control valve 92, and the second circulation connector 91 is connected to the inlet end of the electric control valve 92 through a connecting pipe.

[0064] Its cooling system allows the cold air to circulate internally, increasing the shelf life of pastries placed inside and making them less prone to spoilage.

[0065] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
