Problems solved by technology

[0004] During the drying process of the material, the moisture precipitated from the drying of the material is filled in the box, and the vacuum pump takes away the water while sucking the air. However, in order to improve the drying effect and efficiency, the box is basically in a state of extreme vacuum, and the vacuum pump cannot pump air, which means Unable to take away the moisture, resulting in too much moisture left in the box and high humidity, which affects the drying effect and efficiency of the material

Embodiment 1

[0057] refer to figure 1 , an air supply drying type temperature-humidity-pressure integrated vacuum dryer disclosed in the present invention, comprising a box body 1 and a box door 2, the box door 2 is hinged on the box body 1, so that a closed space is formed in the box body 1; the box body 1 is connected with a vacuum pump 11 for extracting the air in the box body 1, and a pressure gauge 115 is arranged above the box body 1 for detecting the pressure in the box body 1; a heating assembly 14 and a drying assembly are also arranged in the box body 1 13. The heating component 14 is used to provide heat to the drying component 13, and the drying component 13 is used to heat the material to achieve drying. One side of the box body 1 is also provided with an air replenishing device 3, which is used to replenish air in the box body 1 in good time, so that the vacuum pump 11 can continue to work, and remove the moisture precipitated by drying.

[0058] refer to Figure 4 and Fi...

Embodiment 2

[0070] see Figure 10 , a material drying detection method of a vacuum dryer, comprising the steps of:

[0071] Step 1: Detect the temperature of the material in each material box through multiple sensor heads, and judge whether the temperature of the material in each material box reaches the temperature preset value, if not, continue to heat the material;

[0072] Step 2: Use the probe to detect the humidity in the cabinet to determine whether the humidity in the cabinet has reached the preset value. If not, the air supply device will replenish the gas in the cabinet, and the vacuum pump will simultaneously extract the gas and moisture in the cabinet until the humidity in the cabinet reaches The humidity in the body reaches the humidity preset value;

[0073] Step 3: Detect the air pressure in the box with a pressure gauge, and judge whether the air pressure in the box reaches the limit value of vacuum degree. If not, the vacuum pump continues to pump the gas in the box unti...

Abstract

The invention relates to an air supplementing and drying type temperature, humidity and pressure integrated vacuum dryer and a material drying detection method, and relates to the technical field of vacuum dryers. The integrated vacuum dryer comprises a box body and a box door, wherein the box door is hinged to the box body, the box body is communicated with a vacuum pump, and an air supplementingdevice is arranged on one side of the box body; and the air supplementing device comprises an air source and an air supplementing pipe, and two ends of the air supplementing pipe are communicated with the air source and the box body respectively. The integrated vacuum dryer has the effects that the humidity in the box body is reduced, the drying effect and efficiency of materials are improved, the humidity and temperature of the materials in the box body are monitored in real time, the door is closed reliably, and the sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of vacuum dryers, in particular to an air supply drying type vacuum dryer integrated with temperature, humidity and pressure and a material drying detection method. Background technique [0002] The vacuum dryer is specially designed for drying easily decomposed and easily oxidized substances, especially some items with complex components can also be dried quickly, which can be used for high value-added and heat-sensitive agricultural and sideline products, health products, food, medicinal materials, fruits and vegetables, Dehydration and drying of chemical raw materials and other materials, it can also be used for low-temperature concentration of chemical products, removal of crystal water, drying of enzyme preparations, and vacuum extraction of Chinese herbal medicines. [0003] A single-door self-sealing vacuum dryer disclosed in the Chinese patent with the notification number CN208223005U, including a bo...
