Fig. 2 is a top view of the utility model.

【Detailed ways】

The utility model is described in detail below in conjunction with accompanying drawing:

Under the suction of the internal fan of the dryer, the fresh cold air outside directly passes through the air inlet to exchange heat with the heater and then becomes dry hot air, and then exchanges heat with the objects to be dried in the working area and is discharged out of the body , and the drying objects in the working area are gradually evaporated and dried under the action of dry hot air. Since the evaporation of water in the dried object needs to absorb and consume heat energy, the main problem is that the heat dissipation of the heater and the casing are wasteful, and the fluctuation of steam pressure has a great impact on energy consumption. The utility model uses heat insulation in a closed space, Avoid heat loss and save energy.

As shown in Figure 1, a dryer includes a box body 1, a dryer body 2 for dehumidification and heating, and a baking chamber 3 for heat and moisture exchange with the object to be baked. The baking chamber 3 is made of multi-layer heat-insulating material to avoid heat loss and energy consumption. The outside of the baking chamber 3 is provided with a closed door 31, which is also made of multi-layer heat-insulating material. Or take out the article, the airtight door 31 has the function of temperature insulation and airtightness, avoiding the internal heat from scatter, saving energy. The air flow is transported back to the air outlet duct 4 of the baking chamber 3, and the return air duct 5 is sent back to the air flow after the heat and moisture exchange. One side wall of the baking chamber 3 is connected with the air outlet duct 4, and the A plurality of evenly arranged connection holes are provided, and the opposite side wall surface of the baking chamber 3 is connected with the return air duct 5, and a plurality of evenly arranged connection holes are also arranged on the wall surface, and the box body 1 is also provided with a The main body 2 of the dryer cooperates with the balancing machine 6 for auxiliary temperature control and dehumidification. The balancing machine 6 and the main body 2 of the dryer work independently of each other and are connected in parallel to the circulation channel of the air flow. They are only opened and used when needed. Only the main body 2 of the dryer works, and the balance machine 6 assists in heating up in the initial stage of drying. At this time, the balance machine heats up; , control the main body 2 of the dryer and the balancing machine 6 to adjust the heat and moisture exchange process and also set a control template, which can comprehensively control the temperature and humidity of the baking chamber 3 .

The baking chamber 3 is provided with a forced fan 7 for enhancing heat and moisture exchange, and the air circulation is accelerated during operation.

The return air duct 5 is provided with a fresh air outlet 51 for discharging hot and humid air and introducing fresh air, where heat and moisture can be exchanged with the outside world, assisting the work of the dryer main body 2 and the balancing machine 6 .

The balancing machine 6 includes a balancing machine inner unit 61 arranged inside the cabinet 1 for heat and moisture exchange and a balancing machine outer unit 62 arranged outside the cabinet 1 for air exchange with the outside world. The balancing machine inner unit 61 transfers moisture to The external unit 62 of the balancing machine is discharged to the outside, and the dry air flow from the outside can also enter the inside of the box body 1 from the external unit 62 of the balancing machine.

The main body 2 of the dryer and the inner unit 61 of the balancing machine are arranged in the rear box of the baking chamber 3, and the rear wall of the baking chamber 3 is provided with a maintenance door 8 for easy maintenance, which can be accessed through the maintenance door 8. Go to the rear space of the cabinet to repair the main body 2 of the dryer and the balancer 6.

The main body 2 of the dryer is connected with a drainpipe 9 for discharging the moisture formed after the heat and moisture exchange, and discharges the moisture to the outside.

The air outlet duct 4 is provided with an anti-backflow baffle 10 to prevent backflow of the airflow, and the airflow can only circulate in one direction.

When working, open the airtight door 31, put the items to be dried such as food, medicinal materials, etc. into the baking chamber 3, close the baking chamber 3, seal the indoor space, adjust the control template, and the main body of the dryer 2 starts to operate For heating and dehumidification, the balance machine 6 also starts to assist the heating and dehumidification. At the same time, the temperature rises faster and the dehumidification effect is better. After setting the baking time and temperature, the air flows through the dryer host 2 for dehumidification and heating, and then passes through the air outlet 4 Send it to the working area in the baking chamber 3, and perform heat and moisture exchange with the object to be baked in the work area, that is, the temperature rise and moisture vaporization of the object to be dried are taken away, and returned to the oven through the return air duct 5. The main body of the dryer is dehumidified and heated at 2 places, and the cycle is repeated to achieve the purpose of drying the material. When the temperature of the drying room reaches the set temperature, the balance machine is cooled to avoid the temperature of the drying room being too high, and dehumidification at the same time. The fan assists air supply to avoid dead air supply angles, and the air circulation in the baking chamber 3 is faster and the flow area is larger.
