Description

Technical Field

[0001] This utility model relates to the field of pastry food processing technology, specifically to a proofing chamber with uniform temperature and humidity. Background Technology

[0002] Proofing is an important step in the processing of pasta products. It needs to be carried out in an environment of 35℃-40℃ and relative humidity of 80%-90% to allow the dough to expand to twice its original volume.

[0003] Currently, pastry manufacturers typically place pastries in a proofing chamber and then use ductwork to send steam into the chamber for humidification and heating to proof the pastries. However, during humidification, the steam tends to condense inside the ductwork, which reduces humidification efficiency and may cause equipment corrosion. Furthermore, due to the high steam temperature, the humidified steam leads to a high temperature at the air outlet, which, if blown directly onto the pastries, can cause localized overheating and affect the proofing quality. Therefore, the existing technology still has its shortcomings and deficiencies. Utility Model Content

[0004] This invention provides a proofing chamber with uniform temperature and humidity to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a proofing room with uniform temperature and humidity, including a room body, an insulated door on the side wall of the room body, and several sets of regulating mechanisms for adjusting air temperature and humidity installed on both sides of the room body. The regulating mechanism includes a horizontal air duct installed on the top surface of the room body, a return air vent at one end of the horizontal air duct near the middle of the room body, a circulating fan and a heat exchanger installed inside the horizontal air duct, the circulating fan being located near the return air vent, and a vertical air duct connected to the end of the horizontal air duct away from the return air vent. The vertical air duct is installed on the side wall of the room body, and the bottom end of the vertical air duct extends to the lower part of the room body. The bottom end of the vertical air duct is an air outlet, and a vertical partition is installed at the air outlet. The top end of the vertical partition extends into the vertical air duct, and the vertical partition divides the air outlet into a direct blowing area and a humidification area. A humidification pipe is provided inside the vertical partition, and several air jet holes are opened at the bottom of the humidification pipe; a temperature and humidity sensor is installed at one of the return air vents.

[0006] Preferably, a first air guide plate is provided on the outer side of the air outlet, and a second air guide plate is provided on the bottom section of the vertical partition.

[0007] Preferably, a first steam pipe is provided outside the chamber, and a first control valve and a first shut-off valve are installed on the first steam pipe. One end of the first steam pipe extends into the chamber and is connected to the heat exchanger. The outlets of the heat exchanger are connected to a common drain pipe. The end of the drain pipe away from the heat exchanger extends out of the chamber and is equipped with a drain valve.

[0008] Preferably, a second steam pipe is provided outside the chamber, and a second control valve and a second shut-off valve are installed on the second steam pipe. One end of the second steam pipe extends into the chamber and is connected to the humidification pipe.

[0010] Preferably, the roof of the building has several exhaust branch pipes connected to each other, and the exhaust branch pipes are connected to a main exhaust pipe, on which an exhaust fan is installed.

[0011] The beneficial effects of this utility model are as follows: (1) By setting a vertical partition to separate the direct blowing area and the humidification area, the airflow in the humidification area is blown downward to the bottom of the room under the obstruction of the vertical partition and then diffuses and rises to participate in the circulation, avoiding the direct blowing of steam to the surface and ensuring the uniformity of the fermentation.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] like Figure 1-7 As shown, this utility model provides a proofing room with uniform temperature and humidity, including a chamber body 1. A PLC programmable control system 2 is installed on the outer wall of the chamber body 1. An insulated door 3 is installed on the side wall of the chamber body 1. Several sets of regulating mechanisms 4 for adjusting air temperature and humidity are installed on both sides inside the chamber body 1. Each regulating mechanism 4 includes a horizontal air duct 41 installed on the inner ceiling of the chamber body 1. A return air inlet 42 is located at one end of the horizontal air duct 41 near the middle of the chamber body 1. A circulating fan 43 and a heat exchanger 44 are installed inside the horizontal air duct 41. The circulating fan 43 is located near the return air inlet 42. A vertical air duct 45 is connected to the end of the horizontal air duct 41 away from the return air inlet 42. Installed on the side wall of the room 1, the bottom end of the vertical air duct 45 extends to the lower part of the room 1. The bottom end of the vertical air duct 45 is the air outlet 46. A vertical partition 47 is installed at the air outlet 46. The top end of the vertical partition 47 extends into the vertical air duct 45. The vertical partition 47 is fixedly connected to the inner side wall of the vertical air duct 45. The vertical partition 47 divides the air outlet 46 into a direct blowing area 48 and a humidification area 49. A humidification pipe 410 is provided inside the vertical partition 47. Several air jet holes 411 are opened at the bottom of the humidification pipe 410. A temperature and humidity sensor 412 is installed at one of the return air inlets 42. The temperature and humidity sensor 412, the circulating fan 43 and the control system 2 are electrically connected.

[0022] Specifically, during use, the control system 2 activates the circulating fan 43, which drives the air to circulate. The air inside the horizontal duct 41 is heated by the heat exchanger 44 and then blown out from the air outlet 46. Figure 6 As shown, the airflow in the direct blowing zone 48 blows into the space inside the room 1, circulates through the space inside the room 1, and returns through the return air vent 42, forming a cycle, as shown. Figure 7As shown, the jet nozzle 411 sprays steam into the humidification zone 49, increasing the temperature and humidity of the airflow in the humidification zone 49. The airflow in the humidification zone 49, blocked by the vertical baffle 47, blows downwards to the bottom surface of the chamber 1, diffuses, and then rises again to participate in the circulation, avoiding direct blowing onto the surface. Furthermore, when the chamber 1 is large, such as... Figure 1 As shown, the regulating mechanism 4 is set in multiple groups. When the heat preservation door 3 is opened, part of the air blown out by the air outlet 46 of each group of regulating mechanisms 4 in the room 1 will circulate to the return air outlet 42 of other regulating mechanisms 4, so as to mix the air in the room 1 evenly and ensure that the temperature and humidity distribution in the room 1 is uniform.

[0023] This invention separates the direct blowing zone 48 and the humidification zone 49 by setting a vertical partition 47, which prevents the humidifying steam from blowing directly onto the surface and ensures uniform proofing. Secondly, by setting the humidification pipe 410 at the air outlet 46, the path of steam in the air duct is shortened, thereby reducing the risk of condensation on the inner wall of the air duct and improving humidification efficiency.

[0024] In some embodiments, a first steam pipe 5 is provided outside the chamber 1. A first control valve 6 and a first shut-off valve 7 are installed on the first steam pipe 5. The first control valve 6 is electrically connected to the control system 2. One end of the first steam pipe 5 extends into the chamber 1 and is connected to the heat exchanger 44. A drain pipe 8 is connected between the outlets of the heat exchanger 44. The end of the drain pipe 8 away from the heat exchanger 44 extends outside the chamber 1 and is equipped with a drain valve 9. Specifically, the steam pipeline of the steam generator or boiler room is connected to the inlet of the first steam pipe 5. When the temperature and humidity sensor 412 detects that the temperature is lower than the set value, the control system 2 opens the first control valve 6, and the steam enters the heat exchanger 44 through the first steam pipe 5. The steam exchanges heat with the air in the horizontal air duct 41 through the heat exchanger 44, thereby raising the temperature of the air in the horizontal air duct 41. After the heat exchange, the steam cools down and condenses into condensate. The condensate is discharged into the drain pipe 8 network after passing through the drain pipe 8 and the steam trap 9 in sequence. In addition, when the heat exchanger 44 is heating, the worker can control the flow rate of the steam in the first steam pipe 5 through the first shut-off valve 7. The larger the steam flow rate, the faster the heating rate of the heat exchanger 44, so as to adjust the heating rate of the air in the evaporation room according to the site conditions.

[0025] In some embodiments, a second steam pipe 10 is provided outside the chamber 1. A second control valve 11 and a second shut-off valve 12 are installed on the second steam pipe 10. The second control valve 11 is electrically connected to the control system 2. One end of the second steam pipe 10 extends into the chamber 1 and is connected to the humidification pipe 410. Specifically, the steam generator or the steam pipe of the boiler room is connected to the inlet of the second steam pipe 10. When the temperature and humidity sensor 412 detects that the humidity is lower than the set value, the control system 2 opens the second control valve 11. Steam passes through the second steam pipe 10 and the humidification pipe 410 in sequence and is then ejected from the jet hole 411, thereby humidifying the air in the humidification zone 49. In addition, when the jet hole 411 is humidifying, the worker can control the flow rate of the steam in the second steam pipe 10 through the second shut-off valve 12. The greater the steam flow rate, the more steam is ejected from the jet hole 411, thereby adjusting the humidification speed of the air in the humidification room according to the site conditions.

[0026] In some embodiments, the horizontal duct 41 and the vertical duct 45 are connected by an arc-shaped air guide duct 413. The arc-shaped air guide duct 413 can ensure that the airflow turns smoothly, thereby reducing the temperature and humidity fluctuations caused by local wind speed differences.

[0027] In some embodiments, a first air guide plate 414 is provided on the outer side of the air outlet 46, and a second air guide plate 415 is provided on the bottom section of the vertical partition 47. Specifically, the first air guide plate 414 and the second air guide plate 415 play a guiding role, guiding the airflow in the direct blowing zone 48 to diffuse horizontally, so as to heat the space inside the room 1. At the same time, the second air guide plate 415 can also guide the airflow direction in the humidification zone 49, ensuring that the airflow in the humidification zone 49 blows downward toward the bottom surface of the room 1.

[0028] In some embodiments, a plurality of exhaust branch pipes 13 are connected to the top surface of the room 1, and a main exhaust pipe 14 is connected between the plurality of exhaust branch pipes 13. An exhaust fan 15 is installed on the main exhaust pipe 14, and the exhaust fan 15 is electrically connected to the control system 2. Specifically, when the temperature and humidity inside the room 1 exceed the set value, the control system 2 starts the exhaust fan 15. Under the action of the exhaust fan 15, the air inside the room 1 is discharged sequentially through the exhaust port, the exhaust pipe and the main exhaust pipe 14, while an air inlet is provided to replenish fresh air, thereby dehumidifying and de-temperature-reducing the room 1.

[0029] The specific usage process of this utility model is as follows: First, place the dough to be proofed into the chamber 1, close the insulation door 3, and set the target temperature and humidity through the control system 2. The control system 2 then starts the circulating fan 43. Air enters the horizontal air duct 41 from the return air inlet 42, passes through the heat exchanger 44, and then smoothly turns through the arc-shaped air guide duct 413 into the vertical air duct 45, finally being blown out from the air outlet 46, forming a circulating airflow. Next, the temperature and humidity sensor 412 monitors the air temperature and humidity at the return air inlet 42 in real time. If the temperature is lower than the set value, the control system 2 opens the first control valve 6, and steam enters the heat exchanger 44 through the first steam pipe 5, circulating with the air. After the air is heated, the condensate is discharged through the drain pipe 8, which heats the air in the horizontal air duct 41. Then, if the humidity is lower than the set value, the control system 2 opens the second control valve 11, and the steam is delivered to the humidification pipe 410 through the second steam pipe 10. It is then sprayed into the humidification area 49 through the jet hole 411. The steam diffuses downward to the bottom of the room 1 under the guidance of the second air guide plate 415, and then rises to participate in the circulation, avoiding direct blowing to the surface. Finally, when the temperature and humidity exceed the set threshold, the control system 2 starts the exhaust fan 15. The hot air and moisture are discharged through the exhaust branch pipe 13 and the exhaust main pipe 14, while the air inlet replenishes fresh air to maintain the air pressure balance in the room 1.

[0030] In the above embodiments, the connection methods between the control system 2 and the temperature and humidity sensor 412, the circulating fan 43, the first control valve 6, the second control valve 11, and the exhaust fan 15 are existing technologies and will not be described in detail here.

[0031] The above embodiments can be combined with each other.

[0032] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
