Description

A box structure of a drying chamber

【Technical field】

The invention relates to a box structure of a drying chamber.

【Background technique】

In daily life, some vegetables, fruits and medicinal materials often need to be air-dried for storage or transportation, or used to make some bagged foods, such as Luo Han Guo, etc., which are usually weathered naturally, which takes a very long time. The existing dryer mainly puts the electric heating tube under the dryer, and makes it pass an electric current to generate heat. The vegetables and fruits are placed on the top of the dryer, so that the placing plate is directly heated by the electric heating tube to be dried. After use, the following disadvantages are found: the drying time is too long, because the heat of the heating tube only produces drying effect near the heating tube, it is less easy to accept the heat for vegetables and fruits placed far away, resulting in drying The time is long, the drying is uneven, and it also wastes electric energy. In addition, the air inlet or return air outlet of the drying chamber is only set as a flow channel hole, the heat exchange area is small, the air flow is not sufficient, and the drying chamber adopts an airtight design, which is inconvenient for repair or maintenance.

The present invention is made under such background.

A drying chamber box structure as described above is characterized in that: the right wall surface 21 of the drying chamber 2 is provided with an air inlet 211 communicating with the air inlet duct 4, and the air inlet 211 is evenly distributed on the A plurality of through holes on the right side wall form a network structure.

A drying chamber box structure as described above is characterized in that: the left wall surface 22 of the drying chamber 2 is provided with an air outlet 221 communicating with the return air duct 5, and the air outlet 221 is evenly distributed A plurality of through holes on the left side wall of the main body 1 form a network structure.

The box structure of the drying chamber as described above is characterized in that: a sealing strip 71 for isolating water vapor is provided at the frame of the isolation door 7 .

The box structure of the drying chamber as described above is characterized in that: the interior of the drying chamber 2 is provided with a workbench 23 for placing items to be dried.

The beneficial effects of the present invention are: the air inlet and air outlet of the box structure of the drying chamber of the present invention adopt a mesh structure, which are evenly distributed on the entire wall surface, the heat and moisture exchange area is large, the air circulation speed is fast, and the internal heat and moisture exchange air circulation is fast , Good drying quality, high efficiency, high temperature drying airflow for drying, more uniform drying, sufficient heat and moisture exchange; there is an isolation door at the rear, which is convenient for maintenance or repair of the host on the rear side of the dryer cabinet.

【Detailed ways】

The present invention is described in detail below in conjunction with accompanying drawing:

As shown in Figure 1, it includes an outer box body 1, a drying chamber 2 and a machine room 3 are arranged in the outer box body 1, and an air inlet is provided between the drying room 2 and the machine room 3. 4 and return air duct 5, the front end of the outer box 1 is provided with an airtight door 6, and the machine room 3 is provided with a dryer host, from which items can be put in or taken out, and the airtight door 6 has a temperature-proof airtight function, to avoid internal heat dissipation and save energy. The front opening of the drying chamber 2 is connected to the airtight door 6, and the rear wall of the drying chamber 2 is provided with a drying oven that can communicate with the rear space of the outer box 1 to facilitate maintenance. The isolation door 7 of the dryer 8. The inside of the drying chamber 2 is provided with a workbench 23 for placing articles to be dried, and the right wall 21 of the drying chamber 2 is provided with an air inlet 211 communicating with the air inlet duct 4, and the left wall of the drying chamber 2 22 is provided with an air outlet 221 communicating with the return air duct 5 .

The air inlet 3 is connected to the air inlet duct of the dryer, and the incoming airflow is the dry high-temperature airflow after the heat and humidity treatment of the dryer. There are two through holes, forming a network structure, increasing the contact area with the heat and moisture exchange inside the drying chamber, and facilitating sufficient drying.

The air outlet 221 is connected to the return air duct 5 of the dryer, and the airflow after heat and moisture exchange with the article is sent back to the dryer for processing. The air outlet 221 is evenly distributed on the left side wall of the drying chamber 2 A plurality of through holes form a network structure, which increases the contact area with the heat and moisture exchange inside the drying chamber, and facilitates the rapid discharge of the exchanged wet air.

The frame of the isolation door 7 is provided with a sealing strip 71 for isolating water vapor. The host and control components of the dryer are arranged in the rear machine room 3 of the cabinet, and after opening the isolation door 7, one can enter the rear space of the cabinet for repair or maintenance.

When working, open the airtight door 6, put the items to be dried such as food and medicinal materials on the workbench 23 in the baking chamber 2, adjust the control template, set the baking time and temperature, and let the air flow through the main body of the dryer for dehumidification and heating. After warming, it is sent to the working area in the baking room through the air outlet 4 and then through the air inlet 211. In the working area, it exchanges heat and moisture with the object to be baked, that is, the temperature of the object to be dried is increased and the moisture is vaporized. Take it away, go back to the main machine of the dryer through the air outlet 221 through the return air duct 5, and then dehumidify and heat up, and the cycle goes back and forth to achieve the purpose of drying the material.
