Description

All-weather UV oven

technical field

The invention relates to a drying device, in particular to an all-weather ultraviolet drying oven which can make full use of sunlight, timely supplement ultraviolet light, supplement heat, ventilate and dehumidify, and control temperature throughout the process.

Background technique

The drying method is a method of preserving items for a long time by reducing the moisture content of the items. Drying methods include sun exposure method, heating drying method, infrared drying method, microwave drying method, freeze drying method, moisture absorption drying method, etc. Among them, the simplest and most feasible are the sun exposure method and the heating and drying method.

The sun exposure method uses the ultraviolet rays in the sun to sterilize and sterilize; uses the light energy of the sun to convert it into heat energy, increases the temperature of the dried items, and promotes the evaporation of water; uses natural ventilation to remove moisture to achieve the purpose of drying. Its advantages are simple operation and free energy. Its disadvantages are: affected by natural factors such as night, rain, wind, humidity, air pollution, etc., it is difficult to achieve all-weather exposure; the light intensity received at different times during the exposure process is not constant, and the temperature of the exposed items cannot be controlled; During the interval between several sunny days, there is no ultraviolet disinfection and sterilization, so it is easy to breed fungi and bacteria, causing rot and deterioration; when the atmosphere is polluted, the air humidity is high, and the anti-insect measures are not in place, the product quality will be directly affected.

The heating and drying method heats the object to be dried through heat transfer methods such as heat radiation, heat conduction, and hot air convection to promote water evaporation; at the same time, it uses temperature difference or blast to make air convection remove moisture, so as to achieve the purpose of drying. Its advantage is that it is not affected by natural factors such as day and night, weather, climate, air quality, etc., and can be dried at a constant temperature without interruption. Its disadvantages are: due to the absence of ultraviolet light for sterilization, there is a period of time during the drying process that happens to be at the optimum temperature and humidity for bacteria and fungi to multiply easily, and the product is prone to mildew; without utilizing the free natural resource of sunlight, Energy costs are too high.

In the above two drying methods, the sterilization of the drying process is a difficult point. Ultraviolet rays are the general term for radiation with wavelengths from 10nm to 400nm in the electromagnetic spectrum, among which the bactericidal power is the strongest in the range of 250-270nm. When the ultraviolet rays of this band irradiate the bacteria body, the nucleoprotein and ribonucleic acid of the cell strongly absorb the energy of this band, and the chains between them are opened and broken, thus causing the bacteria to die. The ultraviolet disinfection lamp can produce 253.7nm ultraviolet rays, which can concentrate high-intensity ultraviolet rays to sterilize in a short time. It is widely used in the disinfection and sterilization of air, various material surfaces, water or other liquids.

At present, there is no all-weather drying equipment that combines ultraviolet sterilization, drying and drying, and is low in cost.

Contents of the invention

The purpose of the present invention is to design an all-weather ultraviolet drying oven that can make full use of sunlight, supplement ultraviolet light in time, supplement heat, ventilate and dehumidify, and control temperature throughout the process.

The purpose of the present invention is achieved in the following manner:

An all-weather ultraviolet drying box, consisting of box body, box door, lighting glass, ultraviolet lamp, ultraviolet sensor probe, ultraviolet sensor control panel, heating pipe, temperature controller probe, temperature controller control panel, ventilation fan, blackout curtain, Components such as shelves. The lighting glass is on the sunny side of the box; the ultraviolet lamp, heating pipe, shelf, etc. are all in the box; the ventilation fan is connected to the inside and outside of the box, and the dry air outside the box is sent into the box, and the humid air in the box is simultaneously Discharge; temperature controller probe and ultraviolet sensor probe are inside the box; temperature controller control panel and ultraviolet sensor control panel are outside the box, which is convenient for operation and control; the shading curtain is outside the lighting glass of the box body, and the lighting glass is exposed when the shading curtain is closed When the sun shines into the box through the lighting glass, the ultraviolet light and the heat inside the box cannot leak out when the blackout curtain is spread to cover the daylighting glass; The cabinet, the cabinet door, the lighting glass and the shelf together constitute the cabinet system. Daylighting glass, ultraviolet lamp, ultraviolet sensor probe and ultraviolet sensor control panel together constitute the ultraviolet disinfection control system. Daylighting glass, heating pipe, temperature controller probe, temperature controller control panel, ventilation fan, and blackout curtains together constitute a temperature control system. The cabinet door, ventilation fan and temperature control panel together constitute a ventilation and dehumidification system.

Description of drawings

Below in conjunction with accompanying drawing, the present invention will be further described:

Figure 1 is a schematic diagram of an all-weather ultraviolet drying oven. In Figure 1, 1 is the cabinet, 2 is the shelf, 3 is the temperature controller control panel, 4 is the UV sensor control panel, 5 is the blackout curtain, 6 is the lighting glass, 7 is the ultraviolet lamp, and 8 is the cabinet Door, 9 is an ultraviolet sensor probe, 10 is a temperature controller probe, 11 is a heating pipe, and 12 is a ventilation fan.

Detailed ways

The present invention will be further described below in conjunction with embodiment.

According to the texture, size, quantity, water content, drying requirements and other factors of the items to be dried, the drying plan is designed, that is, the indicators such as temperature, ultraviolet intensity, air exchange rate, air exchange frequency, and drying time. Open the cabinet door, put the items to be dried on the shelf, and close the cabinet door. When the sun is sufficient during the day, put away the blackout curtains to allow sunlight to shine into the box through the lighting glass; at night or when the sun is not enough in rainy days, use the heating tube to increase the temperature inside the box, and use the ultraviolet lamp to increase the intensity of ultraviolet radiation; when the temperature inside the box is too high , stop heating the heating pipe, and cool down through the ventilation fan. When the sun is too strong in the daytime, you can properly spread the shading curtain to reduce sunlight radiation; When the humidity is too high, turn on the ventilation fan to ventilate and dehumidify. In short, the temperature control system ensures a constant temperature in the box; the ultraviolet disinfection control system ensures that the ultraviolet radiation intensity is sufficient, and the whole process is disinfected and sterilized; the ventilation and dehumidification system is used to remove moisture and ventilate and dry. After the dry items reach the drying time, ventilate and cool down to room temperature under ultraviolet light. Open the door of the cabinet, take out the items to be dried, and complete the drying process.

Due to the guarantee of temperature control system, ultraviolet disinfection control system, and ventilation and dehumidification system, it is not affected by weather conditions, day and night, and air quality. In a dehumidified environment, the dried items are sterilized and dried around the clock to prevent the dried items from rotting and deteriorating during the drying process.

This is a low-cost all-weather drying equipment that combines ultraviolet sterilization, drying and drying, and is suitable for drying various agricultural products, aquatic products, and Chinese medicinal materials derived from animals, plants, and fungi.
