How to operate a chili dryer safely, and what conditions must be met?

In recent years, chili drying equipment has become a mainstream product. This is mainly because people no longer rely on traditional drying methods for agricultural products, but instead use new chili drying equipment. This not only saves time and labor, but is also energy-efficient and environmentally friendly, resulting in higher profits.

There are two types of new chili drying equipment: one is an air-source heat pump drying room for small-scale production, designed for family farms; the other is a chili mesh belt dryer for larger-scale processing plants and cooperatives. Below is an introduction to these two types of drying machinery to help you choose the right chili drying equipment for your needs.

The working principle of an air-source heat pump chili drying room is that refrigerant is compressed by a compressor into a high-temperature, high-pressure gas, which then enters a condenser to release heat. The released heat is then sent into the drying room by a circulating fan to dry the chilies, gradually evaporating the moisture. A dehumidification system then removes the moisture, achieving the desired drying effect. Air-source heat pump drying rooms use three-phase electricity and have advantages such as high efficiency and energy saving, environmental friendliness and zero pollution, and simple assembly. Because it requires no auxiliary combustion or boilers for heat supply and only needs a small amount of electricity to operate, the drying process is very safe and reliable. Furthermore, the intelligent control system significantly enhances the automation level of the equipment, making it ideal for family farms and farmers with small production volumes. Many users also favor this type of drying equipment for drying chilies, purchasing multiple sets for parallel use to handle large-scale chili drying.

Another type of chili dryer is a batch, continuous production drying device. The main heating methods can include electric heating, steam heating, coal heating, liquefied petroleum gas, natural gas, and biomass pellets. This type of chili dryer simply places the wet chilies to be processed directly into the feeding conveyor. The conveyor's equalizing mechanism distributes them evenly on the conveyor belt, feeding them into the upper mesh belt layer of the dryer, and then they move downwards layer by layer. Each time they enter the next layer, the chilies are automatically turned over, ensuring more even drying. In addition, by using Guoxin's dedicated heat exchange system, the hot air entering the dryer is large in volume and clean and pollution-free, not only improving drying efficiency but also ensuring the quality of the dried chilies. After entering the drying unit, hot air flows upwards through the chili pepper layer on the mesh belt, removing internal moisture and achieving the drying purpose. This chili mesh belt drying equipment is specifically designed for high-volume chili production and processing, boasting advantages such as high processing capacity, rapid dehumidification, uniform drying, and high-quality drying. Therefore, it is highly favored by large-scale chili drying plants and cooperative processing companies.

We are a pioneering enterprise in converting traditional energy dryers to new energy chili dryers. Our edible new energy chili drying production line mainly consists of an intelligent centralized control system, a high-efficiency new energy heat pump unit, a two-way convection circulation air supply system, a heat recovery system, a low-loss dehumidification system, a mesh belt conveyor system, a low-heat insulation drying chamber, and a single-power two-way multi-layer drive system. The entire production line features one-button start-up and a logistics network monitoring system, enabling near-intelligent control and operation.

Utilizing advanced technology, it offers stable performance, high efficiency and energy saving, low consumption and environmental friendliness, truly achieving zero pollution and zero emissions, eliminating safety hazards. It is a superior piece of equipment for converting traditional energy dryers to new energy and environmentally friendly chili dryers. Currently, there are only about 20 new energy chili drying equipment units nationwide, and our company accounts for more than half of them. They are distributed in provinces such as Guizhou, Chongqing, Sichuan, Shaanxi, Xinjiang, Gansu, Henan, and Hubei. The operating cost has been reduced by 60%, and the drying time has been reduced from more than 30 hours to 9 hours. At present, our drying capacity is leading the country.
