Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a constant humidity and constant temperature proofing box. Background Art

[0002] In the production process of flour products, dough proofing is a very important step, which directly affects the quality and taste of the bread baked later. Dough proofing is generally carried out in a proofing box. The proofing box is a device designed according to the fermentation principle of bread. It uses electric heating tubes to heat the water in the water tank through a temperature control circuit, so that the proofing box creates an optimal fermentation environment with a relative humidity of 80-85% and a temperature of 35-40℃. This ensures good dough proofing and can significantly improve the quality of bread. In actual use, before each fermentation, sufficient water needs to be added to the water tank to ensure that the humidity in the box can always be maintained in the optimal range during the fermentation process. However, due to the many steps in bread making, the operator may forget to add water to the water tank, and the water level in the water tank may not be enough for the minimum amount of water required for one proofing, which will affect the dough proofing effect. Utility Model Content

[0003] The purpose of the present invention is to provide a constant humidity and constant temperature proofing box with a reasonable design and easy use in view of the defects and shortcomings of the existing technology, which can effectively solve the defects of the above-mentioned existing technology.

[0005] A heater is provided on the lower side of the water tank. A water pump is provided on one side of the water tank. The water outlet of the water pump is connected to the water tank through a pipe, and the water inlet of the water pump is connected to an external water source through a pipe.

[0006] A water level sensor is fixed on the inner wall of one side of the water tank and is connected to the water pump through a controller;

[0007] An air pump is embedded in and fixed to the lower side of one side wall of the box body, and an air inlet end of the air pump is connected to the top wall of the water tank through a pipe;

[0008] There are several diverter pipes, and they are equidistantly embedded in one side wall of the box from top to bottom. The several diverter pipes are connected by connecting pipes. The lowest diverter pipe is connected to the air pump through the connecting pipe. Several atomizing nozzles are equidistantly arranged on one side of the outer ring wall of the diverter pipe. The atomizing nozzles are inserted in the side wall of the box, and the atomizing nozzles are arranged in the same plane as the inner wall of the box;

[0009] Temperature and humidity sensors, there are several temperature and humidity sensors, and they are fixed equidistantly on the inner wall of the box away from the shunt pipe. The temperature and humidity sensors are connected to the vacuum pump and the heating rod in the support rod through the controller;

[0010] The limiting mechanism is multiple and is symmetrically arranged on multiple support rods in the same row in pairs.

[0011] Through the above technical solution, the dough to be proofed is placed on the support rod through a tray, and then the heating rod, vacuum pump and heater in the support rod are started. The heater heats the water in the water tank, and the water vapor generated after heating is pumped into the diversion pipe, and then sprayed into the box through the atomizing nozzle, thereby increasing the humidity inside the box. The heating rod inside the support rod heats the inside of the box. When the temperature and humidity reach the appropriate heights, the signal is transmitted to the corresponding controller through the temperature and humidity sensor. The controller turns off the vacuum pump and the heating rod in the support rod, thereby ensuring the temperature and humidity inside the box. When the water level in the water tank is low, the water level sensor starts the water pump through the controller, and the water pump pumps external water into the water tank, which will not affect the proofing of the dough.

[0012] As a further improvement of the present invention, the limiting mechanism includes:

[0013] A fixed rod, the fixed rod is set on the upper side of the support rod, and a movable rod is inserted into the interior of the fixed rod. The movable rod passes through the front end of the fixed rod and is suspended on the upper side of the support rod;

[0015] There are two fixing mechanisms, which are symmetrically arranged on the outer bottom wall of the fixing rod in front and back, and are connected to adjacent support rods;

[0016] Through the above technical solution, according to the width of the tray on the lower side of the dough that needs to be proofed, the fixed rod is fixed at the corresponding position through the fixing mechanism, and then the movable rod and the limit rod are pulled to the front side. At this time, the connecting spring is stretched, and the tray is placed between the fixed rods on both sides. The limit rod and the movable rod are loosened, and the movable rod moves toward the inside of the fixed rod under the elastic force of the connecting spring until the limit rod contacts the front side wall of the tray, thereby limiting the tray.

[0018] Through the above technical solution, the connecting spring can be supported by the guide rod, and the movable rod can be limited by the limit plate to prevent the movable rod from moving out of the fixed rod.

[0019] As a further improvement of the present invention, the fixing mechanism includes:

[0020] A fixing block, the fixing block being fixed to the bottom wall of the fixing rod, the fixing block being located between two adjacent support rods, and a plurality of fixing grooves being symmetrically arranged on the annular wall of the support rod;

When the connecting block moves to the corresponding fixing groove, the connecting block is inserted into the fixing groove under the push of the reset spring, thereby limiting the fixing rod.

[0024] As a further improvement of the present invention, limit sliders are fixed on the upper and lower side walls of the connecting block, and the limit sliders are slidably arranged in the slide grooves on the upper and lower inner walls of the fixed block;

[0025] With the above technical solution, the connecting block can be easily slid in the fixed block and the connecting block can be prevented from being removed from the fixed block.
